Adverse Reactions
6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the label: Cytokine Release Syndrome [ see Boxed Warning , Warnings and Precautions (5.1) ] Skin Reactions [ see Warnings and Precautions (5.2) ] Elevated Liver Enzymes [ see Warnings and Precautions (5.3) ] The most common adverse reactions (occurring in ≥ 30%) are cytokine release syndrome, rash, pyrexia, pruritus, fatigue, nausea, chills, abdominal pain, edema, hypotension, dry skin, headache and vomiting ( 6.1 ).
The most common laboratory abnormalities (occurring in ≥50%) are decreased lymphocyte count, increased creatinine, increased glucose, increased aspartate aminotransferase, increased alanine aminotransferase, decreased hemoglobin, and decreased phosphate ( 6.1 ).

6.1 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.
First line metastatic uveal melanoma The safety of KIMMTRAK was evaluated in study IMCgp100-202, a randomized (2:1), open-label, active-controlled trial in patients who had not received prior systemic therapy for metastatic or advanced uveal melanoma [see Clinical Studies (14) ] .
Patients received either KIMMTRAK administered at 20 mcg intravenously on Day 1, 30 mcg intravenously on Day 8, 68 mcg intravenously on Day 15, and 68 mcg intravenously once every week thereafter (N=245) or investigator’s choice treatment (N=111).
The median duration of exposure was 5.3 months (range: 0.3 to 33 months) in patients treated with KIMMTRAK.
Serious adverse reactions occurred in 28% of patients who received KIMMTRAK.
Serious adverse reactions occurring in ≥ 2% of patients were cytokine release syndrome (10%), rashes (4.5%), pyrexia (2.4%), and hypotension (2%).
One patient (0.4%) experienced a fatal adverse reaction (pulmonary embolism).
Adverse reactions led to permanent discontinuation in 3.3% of patients who received KIMMTRAK.
Adverse reactions that led to permanent discontinuation of KIMMTRAK were anaphylactic reaction, brain edema, cytokine release syndrome, fatigue, hepatotoxicity, hypotension, and nausea (each 0.4%).
Adverse reactions resulting in dosage interruption occurred in 25% of patients who received KIMMTRAK.
Adverse reactions which required dosage interruption in ≥ 2% of patients included fatigue (3.7%), lipase increased (2.9%), pyrexia (2.4%), alanine aminotransferase increase (2%), and aspartate aminotransferase increase (2%).
Adverse reactions leading to dose reduction occurred in 5% of patients who received KIMMTRAK.
Adverse reactions which required dosage reduction in ≥ 2% of patients were cytokine release syndrome (2.4%), and rashes (2%).
The most common adverse reactions (≥30%) in patients who received KIMMTRAK were cytokine release syndrome, rash, pyrexia, pruritus, fatigue, nausea, chills, abdominal pain, edema, hypotension, dry skin, headache, and vomiting.
The most common (≥50%) laboratory abnormalities in patient who received KIMMTRAK were decreased lymphocyte count, increased creatinine, increased glucose, increased AST, increased ALT, decreased hemoglobin, and decreased phosphate.
