Phase 1 Study Comparing RPH-030 and Vectibix4 for First-Line Treatment of Metastatic Colorectal Cancer With Wild-Type RAS Using FOLFIRI

What this Trial Is About

Researchers are evaluating the pharmacokinetics, safety, and immune response of two drugs, RPH-030 and Vectibix4, in patients with metastatic colorectal cancer mCRC who have wild-type RAS genes. The study aims to show that these treatments are equivalent in how the body processes them and to compare their safety and immune effects. Additionally, the study will explore how effective these drugs are when used as first-line therapy combined with FOLFIRI chemotherapy. Participants will receive either RPH-030 or Vectibix4 intravenously at 6 mgkg every two weeks along with FOLFIRI chemotherapy, which includes irinotecan, calcium folinate, and fluorouracil. Treatment starts with FOLFIRI for 8 cycles, then continues with a modified de Gramont regimen. The study includes several periods a screening phase, a main period lasting up to 6 months, a continued therapy period up to 1 year where all patients receive RPH-030, and a treatment extension period lasting up to 2 years for patients with stable disease or response. Follow-up visits occur after treatment ends to monitor survival and disease status. Participants will undergo regular tumor assessments approximately every 6 to 8 weeks, hospitalizations for drug administration at specific visits, and blood sampling for pharmacokinetic and safety evaluations. Researchers will monitor drug levels over time, adverse events, immune reactions, and tumor responses. Follow-up includes imaging or phone calls to track overall survival and disease progression. The total study participation can last up to about 2 years with additional follow-up to ensure thorough monitoring of outcomes and safety.
