6.1Clinical 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 pooled safety population described in Warnings and Precautions reflect exposure to the AVMAPKI FAKZYNJA CO-PACK (combination of AVMAPKI 3.2 mg twice weekly and FAKZYNJA 200 mg twice daily) for the first 3 weeks in a 4-week cycle until disease progression or unacceptable toxicity in 136 adult patients with recurrent LGSOC treated on RAMP-201 and FRAME (NCT03875820).
The median duration of treatment was 10 months (range 0 to 51 months). RAMP-201 The safety of AVMAPKI FAKZYNJA CO-PACK was evaluated in RAMP-201, a single-arm multicenter trial in 57 patients with KRAS- mutated recurrent LGSOC [see Clinical Studies (14) ] . Patients received AVMAPKI FAKZYNJA CO-PACK (AVMAPKI 3.2 mg twice weekly and FAKZYNJA 200 mg twice daily) for the first 3 weeks in a 4-week cycle until disease progression or unacceptable toxicity.
The median duration of treatment was 12 months (range 0.03-40). Serious adverse reactions occurred in 32% of patients who received AVMAPKI FAKZYNJA CO-PACK. The most common (≥2%) serious adverse reactions were sepsis (9%), intestinal obstruction (3.6%), pyelonephritis (3.6%), and hydronephrosis (3.6%). Fatal adverse reactions occurred in 3.6% of patients who received AVMAPKI FAKZYNJA CO-PACK, including intestinal obstruction (1.8%) and perforation (1.8%).
Permanent discontinuation of AVMAPKI FAKZYNJA CO-PACK due to an adverse reaction occurred in 14% of patients. The adverse reactions leading to permanent discontinuation included elevations in creatine phosphokinase, dyspnea, malaise, decreased glomerular filtration rate, hyperbilirubinemia, increased alanine aminotransferase, and abdominal pain (1.8% each). Dosage interruptions of AVMAPKI FAKZYNJA CO-PACK due to an adverse reaction occurred in 84% of patients.
Adverse reactions which required dosage interruptions in ≥ 5% of patients included elevations in creatine phosphokinase (25%), hyperbilirubinemia (25%), diarrhea (12%), edema (11%), fatigue (9%), vision blurred (9%), vitreoretinal disorders (7%), transaminitis (7%), paronychia (5%), nausea (5%), abdominal pain (5%), vomiting (5%), dyspnea (5%), sepsis (5%), and rash (5%). Dose reductions of AVMAPKI FAKZYNJA CO-PACK due to an adverse reaction occurred in 44% of patients.
Adverse reactions which required dose reductions in ≥ 5% of patients were elevations in creatine phosphokinase (9%), fatigue (5%), hyperbilirubinemia (5%), and dermatitis acneiform (5%). The most common (≥25%) adverse reactions, including laboratory abnormalities, were increased creatine phosphokinase, nausea, fatigue, increased aspartate aminotransferase, rash, diarrhea, musculoskeletal pain, edema, decreased hemoglobin, increased alanine aminotransferase, vomiting, increased blood bilirubin, increased triglycerides, decreased lymphocyte count, abdominal pain, dyspepsia, dermatitis acneiform, vitreoretinal disorders, increased alkaline phosphatase, stomatitis, pruritus, visual impairment, decreased platelet count, constipation, dry skin, dyspnea, cough, urinary tract infection, and decreased neutrophil count.
