ADVERSE REACTIONS

The following clinically significant adverse reactions are described elsewhere in the labeling.

Severe and Fatal Immune-Mediated Adverse Reactions [see Warnings and Precautions (5.1) ]
Complications of Allogeneic HSCT [see Warnings and Precautions (5.2) ]

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The data in WARNINGS AND PRECAUTIONS reflect exposure to OPDIVO QVANTIG as a single agent in 247 patients enrolled in CHECKMATE-67T, with additional data from intravenous nivolumab single-agent (1994 patients), and from intravenous nivolumab in combination with cabozantinib (320 patients) for select adverse reactions.

Advanced Renal Cell Carcinoma

CHECKMATE-67T was a multicenter, randomized, open-label study in adult patients with advanced or metastatic RCC. Patients received OPDIVO QVANTIG dose of 1,200 mg of nivolumab and 20,000 units of hyaluronidase subcutaneously every 4 weeks (n=247) or 3 mg/kg of nivolumab intravenously every 2 weeks (n=245). Among patients who received OPDIVO QVANTIG, 52% were exposed for 6 months or longer and 20% were exposed for greater than 1 year.

Serious adverse reactions occurred in 28% of patients who received OPDIVO QVANTIG. Serious adverse reactions in >1% of patients included pleural effusion (1.6%), pneumonitis (1.6%), hyperglycemia (1.2%), hyperkalemia (1.2%), hemorrhage (1.2%) and diarrhea (1.2%). Fatal adverse reactions occurred in 3 patients (1.2%) who received OPDIVO QVANTIG and included myocarditis, myositis, and colitis complications.

Permanent discontinuation of OPDIVO QVANTIG due to an adverse reaction occurred in 10% of patients. The most common adverse reaction which resulted in permanent discontinuation was pneumonitis (2%).

Dosage interruptions of OPDIVO QVANTIG due to an adverse reaction occurred in 34% of patients. Adverse reactions which required dosage interruption in >2% of patients included COVID-19 (4.5%), increased blood creatinine (2.8%), anemia, diarrhea, and fatigue (2.4% each).

The most common adverse reactions (≥10%) were musculoskeletal pain, fatigue, pruritus, rash, hypothyroidism, diarrhea, cough, and abdominal pain.

Tables 5 and 6 summarize adverse reactions and laboratory abnormalities, respectively, in CHECKMATE-67T.

Adverse Reactions in Patients Treated with Intravenous Nivolumab

The safety of OPDIVO QVANTIG for its approved indications [see Indications and Usage (1) ] has been established in adequate and well-controlled clinical studies of intravenous nivolumab. Below is a description of adverse reactions in these adequate and well-controlled clinical studies.

First-line Renal Cell Carcinoma

CHECKMATE-214

The safety of intravenous nivolumab with ipilimumab was evaluated in CHECKMATE-214, a randomized open-label trial in 1082 patients with previously untreated advanced RCC; patients received intravenous nivolumab 3 mg/kg over 60 minutes with ipilimumab 1 mg/kg intravenously every 3 weeks for 4 doses followed by intravenous nivolumab as a single agent at a dose of 3 mg/kg by intravenous infusion every 2 weeks (n=547) or sunitinib 50 mg orally daily for the first 4 weeks of a 6-week cycle (n=535) [see Clinical Studies (14.1) ] . The median duration of treatment was 7.9 months (range: 1 day to 21.4+ months) in intravenous nivolumab and ipilimumab-treated patients and 7.8 months (range: 1 day to 20.2+ months) in sunitinib-treated patients. In this trial, 57% of patients in the intravenous nivolumab and ipilimumab arm were exposed to treatment for >6 months and 38% of patients were exposed to treatment for >1 year.

Serious adverse reactions occurred in 59% of patients receiving intravenous nivolumab and ipilimumab. Study therapy was discontinued for adverse reactions in 31% of intravenous nivolumab and ipilimumab patients. Fifty-four percent (54%) of patients receiving intravenous nivolumab and ipilimumab had a dose interruption for an adverse reaction.

The most frequent serious adverse reactions reported in ≥2% of patients treated with intravenous nivolumab and ipilimumab were diarrhea, pyrexia, pneumonia, pneumonitis, hypophysitis, acute kidney injury, dyspnea, adrenal insufficiency, and colitis; in patients treated with sunitinib, they were pneumonia, pleural effusion, and dyspnea. The most common adverse reactions (reported in ≥20% of patients) were fatigue, rash, diarrhea, musculoskeletal pain, pruritus, nausea, cough, pyrexia, arthralgia, and decreased appetite. The most common laboratory abnormalities which have worsened compared to baseline in ≥30% of intravenous nivolumab and ipilimumab-treated patients include increased lipase, anemia, increased creatinine, increased ALT, increased AST, hyponatremia, increased amylase, and lymphopenia.

Tables 7 and 8 summarize adverse reactions and laboratory abnormalities, respectively, that occurred in >15% of intravenous nivolumab and ipilimumab‑treated patients in CHECKMATE-214.

In addition, among patients with TSH ≤ ULN at baseline, a lower proportion of patients experienced a treatment-emergent elevation of TSH > ULN in the intravenous nivolumab and ipilimumab group compared to the sunitinib group (31% and 61%, respectively).

CHECKMATE-9ER

The safety of intravenous nivolumab with cabozantinib was evaluated in CHECKMATE-9ER, a randomized, open-label study in patients with previously untreated advanced RCC. Patients received intravenous nivolumab 240 mg over 30 minutes every 2 weeks with cabozantinib 40 mg orally once daily (n=320) or sunitinib 50 mg daily, administered orally for 4 weeks on treatment followed by 2 weeks off (n=320) [see Clinical Studies (14.1) ] . Cabozantinib could be interrupted or reduced to 20 mg daily or 20 mg every other day. The median duration of treatment was 14 months (range: 0.2 to 27 months) in intravenous nivolumab and cabozantinib-treated patients. In this trial, 82% of patients in the intravenous nivolumab and cabozantinib arm were exposed to treatment for >6 months and 60% of patients were exposed to treatment for >1 year.

Serious adverse reactions occurred in 48% of patients receiving intravenous nivolumab and cabozantinib. The most frequent (≥2%) serious adverse reactions were diarrhea, pneumonia, pneumonitis, pulmonary embolism, urinary tract infection, and hyponatremia. Fatal intestinal perforations occurred in 3 (0.9%) patients.

Adverse reactions leading to discontinuation of either intravenous nivolumab or cabozantinib occurred in 20% of patients: 7% intravenous nivolumab only, 8% cabozantinib only, and 6% both drugs due to same adverse reaction at the same time. Adverse reaction leading to dose interruption or reduction of either intravenous nivolumab or cabozantinib occurred in 83% of patients: 3% intravenous nivolumab only, 46% cabozantinib only, and 21% both drugs due to same adverse reaction at the same time, and 6% both drugs sequentially.

The most common adverse reactions reported in ≥20% of patients treated with intravenous nivolumab and cabozantinib were diarrhea, fatigue, hepatotoxicity, palmar-plantar erythrodysesthesia syndrome, stomatitis, rash, hypertension, hypothyroidism, musculoskeletal pain, decreased appetite, nausea, dysgeusia, abdominal pain, cough, and upper respiratory tract infection.

CHECKMATE-025

The safety of intravenous nivolumab was evaluated in CHECKMATE-025, a randomized open-label trial in 803 patients with advanced RCC who had experienced disease progression during or after at least one anti-angiogenic treatment regimen received intravenous nivolumab 3 mg/kg over 60 minutes by intravenous infusion every 2 weeks (n=406) or everolimus 10 mg daily (n=397) [see Clinical Studies (14.1) ] . The median duration of treatment was 5.5 months (range: 1 day to 29.6+ months) in intravenous nivolumab-treated patients and 3.7 months (range: 6 days to 25.7+ months) in everolimus-treated patients.

Rate of death on treatment or within 30 days of the last dose was 4.7% on the intravenous nivolumab arm. Serious adverse reactions occurred in 47% of patients receiving intravenous nivolumab. Study therapy was discontinued for adverse reactions in 16% of intravenous nivolumab patients. Forty-four percent (44%) of patients receiving intravenous nivolumab had a dose interruption for an adverse reaction.

The most frequent serious adverse reactions in at least 2% of patients were: acute kidney injury, pleural effusion, pneumonia, diarrhea, and hypercalcemia. The most common adverse reactions (≥20%) were fatigue, cough, nausea, rash, dyspnea, diarrhea, constipation, decreased appetite, back pain, and arthralgia. The most common laboratory abnormalities which have worsened compared to baseline in ≥30% of patients include increased creatinine, lymphopenia, anemia, increased AST, increased alkaline phosphatase, hyponatremia, increased triglycerides, and hyperkalemia. In addition, among patients with TSH < ULN at baseline, a greater proportion of patients experienced a treatment-emergent elevation of TSH > ULN in the intravenous nivolumab group compared to the everolimus group (26% and 14%, respectively).

CHECKMATE-037

The safety of intravenous nivolumab was evaluated in CHECKMATE-037, a randomized, open-label trial in 370 patients with unresectable or metastatic melanoma [see Clinical Studies (14.2) ] . Patients had documented disease progression following treatment with ipilimumab and, if BRAF V600 mutation positive, a BRAF inhibitor. The trial excluded patients with autoimmune disease, prior ipilimumab-related Grade 4 adverse reactions (except for endocrinopathies) or Grade 3 ipilimumab-related adverse reactions that had not resolved or were inadequately controlled within 12 weeks of the initiating event, patients with a condition requiring chronic systemic treatment with corticosteroids (>10 mg daily prednisone equivalent) or other immunosuppressive medications, a positive test for hepatitis B or C, and a history of HIV. Patients received intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks (n=268) or investigator’s choice of chemotherapy (n=102): dacarbazine 1000 mg/m ²intravenously every 3 weeks or carboplatin AUC 6 mg/mL/min and paclitaxel 175 mg/m ²intravenously every 3 weeks. The median duration of exposure was 5.3 months (range: 1 day to 13.8+ months) in intravenous nivolumab‑treated patients and was 2 months (range: 1 day to 9.6+ months) in chemotherapy-treated patients. In this ongoing trial, 24% of patients received intravenous nivolumab for >6 months and 3% of patients received intravenous nivolumab for >1 year.

The population characteristics in the intravenous nivolumab group and the chemotherapy group were similar: 66% male, median age 59.5 years, 98% White, baseline Eastern Cooperative Oncology Group (ECOG) performance status 0 (59%) or 1 (41%), 74% with M1c stage disease, 73% with cutaneous melanoma, 11% with mucosal melanoma, 73% received two or more prior therapies for advanced or metastatic disease, and 18% had brain metastasis. There were more patients in the intravenous nivolumab group with elevated lactate dehydrogenase (LDH) at baseline (51% vs. 38%).

Serious adverse reactions occurred in 41% of patients receiving intravenous nivolumab. Intravenous nivolumab was discontinued for adverse reactions in 9% of patients. Twenty-six percent of patients receiving intravenous nivolumab had a dose interruption for an adverse reaction. Grade 3 and 4 adverse reactions occurred in 42% of patients receiving intravenous nivolumab. The most frequent Grade 3 and 4 adverse reactions reported in 2% to <5% of patients receiving intravenous nivolumab were abdominal pain, hyponatremia, increased aspartate aminotransferase, and increased lipase. The most common adverse reaction (reported in ≥20% of patients) was rash.

Tables 13 and 14 summarize the adverse reactions and laboratory abnormalities, respectively, in CHECKMATE-037.

CHECKMATE-066

The safety of intravenous nivolumab was also evaluated in CHECKMATE-066, a randomized, double-blind, active‑controlled trial in 411 previously untreated patients with BRAF V600 wild-type unresectable or metastatic melanoma [see Clinical Studies (14.2) ] . The trial excluded patients with autoimmune disease and patients requiring chronic systemic treatment with corticosteroids (>10 mg daily prednisone equivalent) or other immunosuppressive medications. Patients received intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks (n=206) or dacarbazine 1000 mg/m ²intravenously every 3 weeks (n=205). The median duration of exposure was 6.5 months (range: 1 day to 16.6 months) in intravenous nivolumab-treated patients. In this trial, 47% of patients received intravenous nivolumab for >6 months and 12% of patients received intravenous nivolumab for >1 year.

The trial population characteristics in the intravenous nivolumab group and dacarbazine group: 59% male, median age 65 years, 99.5% White, 61% with M1c stage disease, 74% with cutaneous melanoma, 11% with mucosal melanoma, 4% with brain metastasis, and 37% with elevated LDH at baseline. There were more patients in the intravenous nivolumab group with ECOG performance status 0 (71% vs. 59%).

Serious adverse reactions occurred in 36% of patients receiving intravenous nivolumab. Adverse reactions led to permanent discontinuation of intravenous nivolumab in 7% of patients and dose interruption in 26% of patients; no single type of adverse reaction accounted for the majority of intravenous nivolumab discontinuations. Grade 3 and 4 adverse reactions occurred in 41% of patients receiving intravenous nivolumab.

The most frequent Grade 3 and 4 adverse reactions reported in ≥2% of patients receiving intravenous nivolumab were increased gamma-glutamyl transferase (3.9%) and diarrhea (3.4%). The most common adverse reactions (reported in ≥20% of patients and at a higher incidence than in the dacarbazine arm) were fatigue, musculoskeletal pain, rash, and pruritus.

CHECKMATE-067

The safety of intravenous nivolumab, administered with ipilimumab or as a single agent, was evaluated in CHECKMATE-067, a randomized (1:1:1), double-blind trial in 937 patients with previously untreated, unresectable or metastatic melanoma [see Clinical Studies (14.2) ] . The trial excluded patients with autoimmune disease, a medical condition requiring systemic treatment with corticosteroids (more than 10 mg daily prednisone equivalent) or other immunosuppressive medication within 14 days of the start of study therapy, a positive test result for hepatitis B or C, or a history of HIV.

Patients were randomized to receive:

Intravenous nivolumab 1 mg/kg over 60 minutes with ipilimumab 3 mg/kg by intravenous infusion every 3 weeks for 4 doses followed by intravenous nivolumab as a single agent at a dose of 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks (nivolumab and ipilimumab arm; n=313), or
Intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks (nivolumab arm; n=313), or
Ipilimumab 3 mg/kg by intravenous infusion every 3 weeks for up to 4 doses (ipilimumab arm; n=311).

The median duration of exposure to intravenous nivolumab was 2.8 months (range: 1 day to 36.4 months) for the intravenous nivolumab and ipilimumab arm and 6.6 months (range: 1 day to 36.0 months) for the intravenous nivolumab arm. In the intravenous nivolumab and ipilimumab arm, 39% were exposed to intravenous nivolumab for ≥6 months and 30% exposed for >1 year. In the intravenous nivolumab arm, 53% were exposed for ≥6 months and 40% for >1 year.

The population characteristics were: 65% male, median age 61 years, 97% White, baseline ECOG performance status 0 (73%) or 1 (27%), 93% with American Joint Committee on Cancer (AJCC) Stage IV disease, 58% with M1c stage disease; 36% with elevated LDH at baseline, 4% with a history of brain metastasis, and 22% had received adjuvant therapy.

Serious adverse reactions (74% and 44%), adverse reactions leading to permanent discontinuation (47% and 18%) or to dosing delays (58% and 36%), and Grade 3 or 4 adverse reactions (72% and 51%) all occurred more frequently in the intravenous nivolumab and ipilimumab arm relative to the intravenous nivolumab arm.

The most frequent (≥10%) serious adverse reactions in the intravenous nivolumab and ipilimumab arm and the intravenous nivolumab arm, respectively, were diarrhea (13% and 2.2%), colitis (10% and 1.9%), and pyrexia (10% and 1%). The most frequent adverse reactions leading to discontinuation of both drugs in the intravenous nivolumab and ipilimumab arm and of intravenous nivolumab in the intravenous nivolumab arm, respectively, were colitis (10% and 0.6%), diarrhea (8% and 2.2%), increased ALT (4.8% and 1%), increased AST (4.5% and 0.6%), and pneumonitis (1.9% and 0.3%).

The most common (≥20%) adverse reactions in the intravenous nivolumab and ipilimumab arm were fatigue, diarrhea, rash, nausea, pyrexia, pruritus, musculoskeletal pain, vomiting, decreased appetite, cough, headache, dyspnea, upper respiratory tract infection, arthralgia, and increased transaminases.

Neoadjuvant and Adjuvant Treatment of Resectable (Tumors ≥4 cm or Node Positive) Non-Small Cell Lung Cancer

CHECKMATE-77T

The safety of intravenous nivolumab in combination with neoadjuvant platinum-doublet chemotherapy followed by surgery and continued adjuvant treatment with intravenous nivolumab as a single agent after surgery was evaluated in CHECKMATE-77T, a randomized, double-blind, multicenter trial in patients with previously untreated resectable Stage IIA (>4 cm) to IIIB (T3N2 or T4N2) NSCLC (per the AJCC Cancer Staging Manual 8th Edition) [see Clinical Studies (14.5) ] . Patients with active autoimmune disease or a medical condition that required immunosuppression were ineligible. The median duration of exposure to intravenous nivolumab was 10.3 months (range: 1 day to 22.3 months).

The study population characteristics were: median age 66 years (range: 35 - 86); 71% male; 72% White, 25% Asian, 1.7% Black/African American, and 1.5% other race; and 6% Hispanic or Latino.

Adverse reactions occurring in patients with resectable NSCLC receiving intravenous nivolumab in combination with platinum-doublet chemotherapy, given as neoadjuvant treatment and followed as a single agent adjuvant treatment after surgery, were generally similar to those occurring in patients in other clinical trials across tumor types receiving intravenous nivolumab in combination with chemotherapy.

Neoadjuvant Phase of CHECKMATE-77T

A total of 228 patients received at least 1 dose of intravenous nivolumab in combination with platinum-doublet chemotherapy as neoadjuvant treatment and 230 patients received at least 1 dose of placebo in combination with platinum-doublet chemotherapy as neoadjuvant treatment.

Serious adverse reactions occurred in 21% of patients who received intravenous nivolumab in combination with platinum-doublet chemotherapy as neoadjuvant treatment; the most frequent (≥2%) serious adverse reactions was pneumonia. Fatal adverse reactions occurred in 2.2% of patients, due to cerebrovascular accident, COVID-19 infection, hemoptysis, pneumonia, and pneumonitis (0.4% each).

Permanent discontinuation of any study drug due to an adverse reaction occurred in 13% of patients who received intravenous nivolumab in combination with platinum-doublet chemotherapy as neoadjuvant treatment; the most frequent (≥1%) adverse reaction that led to permanent discontinuation of any study drug was peripheral sensory neuropathy (2.2%).

Of the 228 intravenous nivolumab-treated patients and 230 placebo-treated patients who received neoadjuvant treatment, 5.3% (n=12) and 3.5% (n=8), respectively, did not receive surgery due to adverse reactions. The adverse reactions that led to cancellation of surgery in intravenous nivolumab-treated patients were cerebrovascular accident, pneumonia, and colitis/diarrhea (2 patients each) and acute coronary syndrome, myocarditis, hemoptysis, pneumonitis, COVID-19, and myositis (1 patient each).

Of the 178 intravenous nivolumab-treated patients who received surgery, 4.5% (n=8) experienced delay of surgery (surgery more than 6 weeks from last neoadjuvant treatment) due to adverse reactions. Of the 178 placebo-treated patients who received surgery, 3.9% (n=7) experienced delay of surgery due to adverse reactions.

Of the 178 intravenous nivolumab-treated patients who received surgery, 7% (n=13) did not receive adjuvant treatment due to adverse reactions. Of the 178 placebo-treated patients who received surgery, 2.8% (n=5) did not receive adjuvant treatment due to adverse reactions.

Adjuvant Phase of CHECKMATE-77T

A total of 142 patients in the intravenous nivolumab arm and 152 patients in the placebo arm received at least 1 dose of adjuvant treatment.

Of the patients who received single agent intravenous nivolumab as adjuvant treatment, 22% experienced serious adverse reactions; the most frequent serious adverse reaction was pneumonitis/ILD (2.8%). One fatal adverse reaction due to COVID-19 occurred. Permanent discontinuation of adjuvant intravenous nivolumab due to an adverse reaction occurred in 14% of patients; the most frequent (≥1%) adverse reactions that led to permanent discontinuation of adjuvant intravenous nivolumab were pneumonitis (4.2%) and diarrhea (1.4%).

Second-line Treatment of Metastatic NSCLC

CHECKMATE-017 and CHECKMATE-057

The safety of intravenous nivolumab was evaluated in CHECKMATE-017, a randomized open-label, multicenter trial in patients with metastatic squamous NSCLC and progression on or after one prior platinum doublet-based chemotherapy regimen and in CHECKMATE-057, a randomized, open-label, multicenter trial in patients with metastatic non-squamous NSCLC and progression on or after one prior platinum doublet-based chemotherapy regimen [see Clinical Studies (14.6) ] . These trials excluded patients with active autoimmune disease, medical conditions requiring systemic immunosuppression, or with symptomatic interstitial lung disease. Patients received intravenous nivolumab 3 mg/kg over 60 minutes by intravenous infusion every 2 weeks or docetaxel 75 mg/m ²intravenously every 3 weeks. The median duration of therapy in intravenous nivolumab-treated patients in CHECKMATE-017 was 3.3 months (range: 1 day to 21.7+ months) and in CHECKMATE-057 was 2.6 months (range: 0 to 24.0+ months). In CHECKMATE-017, 36% of patients received intravenous nivolumab for at least 6 months and 18% of patients received intravenous nivolumab for at least 1 year and in CHECKMATE-057, 30% of patients received intravenous nivolumab for >6 months and 20% of patients received intravenous nivolumab for >1 year.

Across both trials, the median age of intravenous nivolumab-treated patients was 61 years (range: 37 to 85); 38% were ≥65 years of age, 61% were male, and 91% were White. Ten percent of patients had brain metastases and ECOG performance status was 0 (26%) or 1 (74%).

In CHECKMATE-057, in the intravenous nivolumab arm, seven deaths were due to infection including one case of Pneumocystis jirovecii pneumonia, four were due to pulmonary embolism, and one death was due to limbic encephalitis. Serious adverse reactions occurred in 46% of patients receiving intravenous nivolumab. Intravenous nivolumab was discontinued in 11% of patients and was delayed in 28% of patients for an adverse reaction.

The most frequent serious adverse reactions reported in ≥2% of patients receiving intravenous nivolumab were pneumonia, pulmonary embolism, dyspnea, pyrexia, pleural effusion, pneumonitis, and respiratory failure. Across both trials, the most common adverse reactions (≥20%) were fatigue, musculoskeletal pain, cough, dyspnea, and decreased appetite.

Tables 25 and 26 summarize selected adverse reactions and laboratory abnormalities, respectively, in CHECKMATE-057.

Squamous Cell Carcinoma of the Head and Neck

CHECKMATE-141

The safety of intravenous nivolumab was evaluated in CHECKMATE-141, a randomized, active-controlled, open-label, multicenter trial in patients with recurrent or metastatic SCCHN with progression during or within 6 months of receiving prior platinum-based therapy [see Clinical Studies (14.7) ] . The trial excluded patients with active autoimmune disease, medical conditions requiring systemic immunosuppression, or recurrent or metastatic carcinoma of the nasopharynx, squamous cell carcinoma of unknown primary histology, salivary gland or non-squamous histologies (e.g., mucosal melanoma). Patients received intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks (n=236) or investigator’s choice of either cetuximab (400 mg/m ²initial dose intravenously followed by 250 mg/m ²weekly), or methotrexate (40 to 60 mg/m ²intravenously weekly), or docetaxel (30 to 40 mg/m ²intravenously weekly). The median duration of exposure to nivolumab was 1.9 months (range: 1 day to 16.1+ months) in intravenous nivolumab-treated patients. In this trial, 18% of patients received intravenous nivolumab for >6 months and 2.5% of patients received intravenous nivolumab for >1 year.

The median age of all randomized patients was 60 years (range: 28 to 83); 28% of patients in the intravenous nivolumab group were ≥65 years of age and 37% in the comparator group were ≥65 years of age, 83% were male and 83% were White, 12% were Asian, and 4% were Black. Baseline ECOG performance status was 0 (20%) or 1 (78%), 45% of patients received only one prior line of systemic therapy, the remaining 55% of patients had two or more prior lines of therapy, and 90% had prior radiation therapy.

Serious adverse reactions occurred in 49% of patients receiving intravenous nivolumab. Intravenous nivolumab was discontinued in 14% of patients and was delayed in 24% of patients for an adverse reaction. Adverse reactions and laboratory abnormalities occurring in patients with SCCHN were generally similar to those occurring in patients with melanoma and NSCLC.

The most frequent serious adverse reactions reported in ≥2% of patients receiving intravenous nivolumab were pneumonia, dyspnea, respiratory failure, respiratory tract infection, and sepsis. The most common adverse reactions occurring in ≥10% of intravenous nivolumab-treated patients and at a higher incidence than investigator’s choice were cough and dyspnea. The most common laboratory abnormalities occurring in ≥10% of intravenous nivolumab-treated patients and at a higher incidence than investigator’s choice were increased alkaline phosphatase, increased amylase, hypercalcemia, hyperkalemia, and increased TSH.

CHECKMATE-274

The safety of intravenous nivolumab was evaluated in CHECKMATE-274, a randomized, double‑blind, multicenter trial of adjuvant intravenous nivolumab versus placebo in adult patients who had undergone radical resection of UC originating in the bladder or upper urinary tract (renal pelvis or ureter) and were at high risk of recurrence [see Clinical Studies (14.8) ] . Patients received intravenous nivolumab 240 mg by intravenous infusion over 30 minutes every 2 weeks (n=351) or placebo (n=348) until recurrence or unacceptable toxicity for a maximum of 1 year. The median duration of intravenous nivolumab treatment was 8.8 months (range: 0 to 12.5).

Serious adverse reactions occurred in 30% of intravenous nivolumab patients. The most frequent serious adverse reaction reported in ≥2% of patients was urinary tract infection. Fatal adverse reactions occurred in 1% of patients; these included events of pneumonitis (0.6%). Intravenous nivolumab was discontinued for adverse reactions in 18% of patients. Intravenous nivolumab was delayed for adverse reaction in 33% of patients.

The most common adverse reactions (reported in ≥20% of patients) were rash, fatigue, diarrhea, pruritus, musculoskeletal pain, and urinary tract infection.

First-line Treatment of Unresectable or Metastatic UC

CHECKMATE-901

The safety of intravenous nivolumab was evaluated in CHECKMATE-901, a randomized, open-label trial in cisplatin-eligible patients with unresectable or metastatic UC [see Clinical Studies (14.8) ] . Patients received either intravenous nivolumab 360 mg with cisplatin and gemcitabine every 3 weeks for up to 6 cycles followed by single-agent intravenous nivolumab 480 mg every 4 weeks up to 2 years (n=304), or cisplatin and gemcitabine chemotherapy every 3 weeks for up to 6 cycles (n=288). Patients discontinuing cisplatin alone were permitted to switch to carboplatin.

Among patients who received intravenous nivolumab with chemotherapy, the median duration of intravenous nivolumab exposure was 7.4 months (range: 0.03 to 47.9 months). Serious adverse reactions occurred in 48% of patients receiving intravenous nivolumab in combination with chemotherapy. The most frequent serious adverse reactions reported in ≥2% of patients who received intravenous nivolumab with chemotherapy were urinary tract infection (4.9%), acute kidney injury (4.3%), anemia (3%), pulmonary embolism (2.6%), sepsis (2.3%), and platelet count decreased (2.3%). The most common adverse reactions (reported in ≥20% of patients) were nausea, fatigue, musculoskeletal pain, constipation, decreased appetite, rash, vomiting, and peripheral neuropathy.

Fatal adverse reactions occurred in 3.6% of patients who received intravenous nivolumab in combination with chemotherapy; these included sepsis (1%).

Intravenous nivolumab and/or chemotherapy were discontinued in 30% of patients and were delayed in 67% of patients for an adverse reaction.

Previously Treated Advanced or Metastatic UC

CHECKMATE-275

The safety of intravenous nivolumab was evaluated in CHECKMATE-275, a single arm trial in which 270 patients with locally advanced or metastatic UC had disease progression during or following platinum-containing chemotherapy or had disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy [see Clinical Studies (14.8) ] . Patients received intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks until disease progression or unacceptable toxicity. The median duration of treatment was 3.3 months (range: 0 to 13.4+). Forty-six percent (46%) of patients had a dose interruption for an adverse reaction.

Fourteen patients (5.2%) died from causes other than disease progression. This includes 4 patients (1.5%) who died from pneumonitis or cardiovascular failure which was attributed to treatment with intravenous nivolumab. Serious adverse reactions occurred in 54% of patients. Intravenous nivolumab was discontinued for adverse reactions in 17% of patients.

The most frequent serious adverse reactions reported in ≥2% of patients were urinary tract infection, sepsis, diarrhea, small intestine obstruction, and general physical health deterioration. The most common adverse reactions (reported in ≥20% of patients) were fatigue, musculoskeletal pain, nausea, and decreased appetite.

In CHECKMATE-142, 74 patients with mCRC received intravenous nivolumab 3 mg/kg by intravenous infusion over 60 minutes every 2 weeks until disease progression or until intolerable toxicity and 119 patients with mCRC received intravenous nivolumab 3 mg/kg and ipilimumab 1 mg/kg every 3 weeks for 4 doses, then intravenous nivolumab 3 mg/kg every 2 weeks until disease progression or until unacceptable toxicity.

In the intravenous nivolumab with ipilimumab cohort, serious adverse reactions occurred in 47% of patients. Treatment was discontinued in 13% of patients and delayed in 45% of patients for an adverse reaction. The most frequent serious adverse reactions reported in ≥2% of patients were colitis/diarrhea, hepatic events, abdominal pain, acute kidney injury, pyrexia, and dehydration. The most common adverse reactions (reported in ≥20% of patients) were fatigue, diarrhea, pyrexia, musculoskeletal pain, abdominal pain, pruritus, nausea, rash, decreased appetite, and vomiting.

Tables 35 and 36 summarize adverse reactions and laboratory abnormalities, respectively, in CHECKMATE-142. Based on the design of CHECKMATE-142, the data below cannot be used to identify statistically significant differences between the two cohorts summarized below for any adverse reaction.

CHECKMATE-040

The safety of intravenous nivolumab 1 mg/kg in combination with ipilimumab 3 mg/kg was evaluated in a subgroup comprising 49 patients with HCC and Child-Pugh Class A cirrhosis enrolled in Cohort 4 of CHECKMATE-040, a multicenter, multiple-cohort, open-label trial [see Clinical Studies (14.10) ] who progressed on or were intolerant to sorafenib. Intravenous nivolumab and ipilimumab were administered every 3 weeks for 4 doses, followed by single-agent intravenous nivolumab 240 mg every 2 weeks until disease progression or unacceptable toxicity. During the intravenous nivolumab and ipilimumab combination period, 33 of 49 (67%) patients received all 4 planned doses of intravenous nivolumab and ipilimumab. During the entire treatment period, the median duration of exposure to intravenous nivolumab was 5.1 months (range: 0 to 35+ months) and to ipilimumab was 2.1 months (range: 0 to 4.5 months). Forty-seven percent of patients were exposed to treatment for >6 months, and 35% of patients were exposed to treatment for >1 year. Serious adverse reactions occurred in 59% of patients. Treatment was discontinued in 29% of patients and delayed in 65% of patients for an adverse reaction.

The most frequent serious adverse reactions (reported in ≥4% of patients) were pyrexia, diarrhea, anemia, increased AST, adrenal insufficiency, ascites, esophageal varices hemorrhage, hyponatremia, increased blood bilirubin, and pneumonitis.

Esophageal Cancer

Adjuvant Treatment of Resected Esophageal or Gastroesophageal Junction Cancer

CHECKMATE-577

The safety of intravenous nivolumab was evaluated in CHECKMATE-577, a randomized, placebo-controlled, double-blinded, multicenter trial in 792 treated patients with completely resected (negative margins) esophageal or gastroesophageal junction cancer who had residual pathologic disease following chemoradiotherapy (CRT) [see Clinical Studies (14.11) ] . The trial excluded patients who did not receive concurrent CRT prior to surgery, had stage IV resectable disease, autoimmune disease, or any condition requiring systemic treatment with either corticosteroids (>10 mg daily prednisone or equivalent) or other immunosuppressive medications. Patients received either intravenous nivolumab 240 mg or placebo by intravenous infusion over 30 minutes every 2 weeks for 16 weeks followed by 480 mg or placebo by intravenous infusion over 30 minutes every 4 weeks beginning at week 17. Patients were treated until disease recurrence, unacceptable toxicity, or for up to 1‑year total duration. The median duration of exposure was 10.1 months (range: <0.1 to 14 months) in intravenous nivolumab-treated patients and 9 months (range: <0.1 to 15 months) in placebo-treated patients. Among patients who received intravenous nivolumab, 61% were exposed for >6 months and 54% were exposed for >9 months.

Serious adverse reactions occurred in 33% of patients receiving intravenous nivolumab. A serious adverse reaction reported in ≥2% of patients who received intravenous nivolumab was pneumonitis. A fatal adverse reaction of myocardial infarction occurred in one patient who received intravenous nivolumab.

Intravenous nivolumab was discontinued in 12% of patients and was delayed in 28% of patients for an adverse reaction.

Previously-Treated Unresectable Advanced, Recurrent or Metastatic Esophageal Squamous Cell Carcinoma (ESCC)

ATTRACTION-3

The safety of intravenous nivolumab was evaluated in ATTRACTION-3, a randomized, active-controlled, open‑label, multicenter trial in 209 patients with unresectable advanced, recurrent or metastatic ESCC refractory or intolerant to at least one fluoropyrimidine- and platinum‑based chemotherapy [see Clinical Studies (14.11) ] . The trial excluded patients who were refractory or intolerant to taxane therapy, had brain metastases that were symptomatic or required treatment, had autoimmune disease, used systemic corticosteroids or immunosuppressants, had apparent tumor invasion of organs adjacent to the esophageal tumor or had stents in the esophagus or respiratory tract. Patients received intravenous nivolumab 240 mg by intravenous infusion over 30 minutes every 2 weeks (n=209) or investigator’s choice: docetaxel 75 mg/m ²intravenously every 3 weeks (n=65) or paclitaxel 100 mg/m ²intravenously once a week for 6 weeks followed by 1 week off (n=143). Patients were treated until disease progression or unacceptable toxicity. The median duration of exposure was 2.6 months (range: 0 to 29.2 months) in intravenous nivolumab-treated patients and 2.6 months (range: 0 to 21.4 months) in docetaxel- or paclitaxel-treated patients. Among patients who received intravenous nivolumab, 26% were exposed for >6 months and 10% were exposed for >1 year.

Serious adverse reactions occurred in 38% of patients receiving intravenous nivolumab. Serious adverse reactions reported in ≥2% of patients who received intravenous nivolumab were pneumonia, esophageal fistula, interstitial lung disease and pyrexia. The following fatal adverse reactions occurred in patients who received intravenous nivolumab: interstitial lung disease or pneumonitis (1.4%), pneumonia (1.0%), septic shock (0.5%), esophageal fistula (0.5%), gastrointestinal hemorrhage (0.5%), pulmonary embolism (0.5%), and sudden death (0.5%).

Intravenous nivolumab was discontinued in 13% of patients and was delayed in 27% of patients for an adverse reaction.

Tables 45 and 46 summarize the adverse reactions and laboratory abnormalities, respectively, in ATTRACTION-3.

Gastric Cancer, Gastroesophageal Junction Cancer, and Esophageal Adenocarcinoma

CHECKMATE-649

The safety of intravenous nivolumab in combination with chemotherapy was evaluated in CHECKMATE-649, a randomized, multicenter, open-label trial in patients with previously untreated advanced or metastatic gastric cancer, gastroesophageal junction cancer, and esophageal adenocarcinoma [see Clinical Studies (14.12) ] . The trial excluded patients who were known human epidermal growth factor receptor 2 (HER2) positive or had untreated central nervous system (CNS) metastases. Patients were randomized to receive intravenous nivolumab in combination with chemotherapy or chemotherapy. Patients received one of the following treatments:

intravenous nivolumab 240 mg in combination with mFOLFOX6 (fluorouracil, leucovorin and oxaliplatin) every 2 weeks or mFOLFOX6 every 2 weeks.
intravenous nivolumab 360 mg in combination with CapeOX (capecitabine and oxaliplatin) every 3 weeks or CapeOX every 3 weeks.

Patients were treated with intravenous nivolumab in combination with chemotherapy or chemotherapy until disease progression, unacceptable toxicity, or up to 2 years. The median duration of exposure was 6.8 months (range: 0 to 33.5 months) in intravenous nivolumab and chemotherapy-treated patients. Among patients who received intravenous nivolumab and chemotherapy, 54% were exposed for >6 months and 28% were exposed for >1 year.

Fatal adverse reactions occurred in 16 (2.0%) patients who were treated with intravenous nivolumab in combination with chemotherapy; these included pneumonitis (4 patients), febrile neutropenia (2 patients), stroke (2 patients), gastrointestinal toxicity, intestinal mucositis, septic shock, pneumonia, infection, gastrointestinal bleeding, mesenteric vessel thrombosis, and disseminated intravascular coagulation. Serious adverse reactions occurred in 52% of patients treated with intravenous nivolumab in combination with chemotherapy. Intravenous nivolumab and/or chemotherapy were discontinued in 44% of patients and at least one dose was withheld in 76% of patients due to an adverse reaction.

The most frequent serious adverse reactions reported in ≥2% of patients treated with intravenous nivolumab in combination with chemotherapy were vomiting (3.7%), pneumonia (3.6%), anemia (3.6%), pyrexia (2.8%), diarrhea (2.7%), febrile neutropenia (2.6%), and pneumonitis (2.4%). The most common adverse reactions reported in ≥20% of patients treated with intravenous nivolumab in combination with chemotherapy were peripheral neuropathy, nausea, fatigue, diarrhea, vomiting, decreased appetite, abdominal pain, constipation, and musculoskeletal pain.
