6.1 Clinical Trials Experience Because clinical trials are conducted under varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to those observed in the clinical trials of another drug and may not reflect the rates observed in practice.
The data described in the WARNINGS AND PRECAUTIONS reflect exposure to penpulimab-kcqx in 146 patients in Study AK105-304 [see Clinical Studies (14.1) ] .
Patients received 6 cycles every 3 weeks of intravenous penpulimab-kcqx 200 mg in combination with either cisplatin 80 mg/m 2 or carboplatin AUC 5 and gemcitabine 1000 mg/m 2 followed by single-agent penpulimab-kcqx 200 mg every 3 weeks until disease progression or a maximum of 24 months.
Among the 146 patients who received penpulimab-kcqx in combination with either cisplatin or carboplatin and gemcitabine, 71% were exposed for 6 months or longer and 38% were exposed for greater than one year.
In this safety population, the most common (≥ 20%) adverse reactions were nausea (58%), vomiting (55%), hypothyroidism (45%), constipation (41%), decreased appetite (36%), decreased weight (26%), cough (25%), COVID-19 infection (25%), fatigue (25%), rash (24%) and pyrexia (21%).
The most common Grade 3 to 4 laboratory abnormalities (≥ 2%) were decreased lymphocytes (70%), decreased neutrophils (61%), decreased white blood cells (58%), decreased hemoglobin (49%), decreased platelets (33%), decreased potassium (14%), increased lipase (11%), increased ALT (8%), decreased sodium (7%), increased AST (6%), increased triglycerides (4.3%), decreased magnesium (4.2%), decreased CPK (4.1%), increased amylase (2.9%), increased potassium (2.8%), increased cholesterol (2.2%), increased calcium (2.1%) and increased blood bilirubin (2.1%).
5 WARNINGS AND PRECAUTIONS Immune-Mediated Adverse Reactions ( 5.1 ) o Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, including the following: immune-mediated pneumonitis, immune-mediated colitis, immune-mediated hepatitis and hepatotoxicity, immune-mediated endocrinopathies, immune-mediated dermatologic adverse reactions, immune-mediated nephritis and renal dysfunction, immune-mediated dermatologic adverse reactions and solid organ transplant rejection.
o Monitor for early identification and management.
Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment.
o Withhold or permanently discontinue penpulimab-kcqx based on severity and type of reaction.
Infusion-Related Reactions: Interrupt, slow the rate of infusion, or permanently discontinue penpulimab-kcqx based on the severity of the reaction.
Like all medications, Penpulimab Kcqx can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
