A Master Protocol for the Multi-Cohort, Open-Label, Phase 1/2 Study of DCC-3084 as Monotherapy and in Combination With Other Antitumor Agents in Participants With Advanced Malignancies Driven by the MAPK Pathway

Trial ID: NCT06287463

Interventional - Phase 1 - Terminated

This is a multicenter clinical trial to evaluate DCC-3084 alone or in combination with other cancer therapies in participants with advanced cancers. Module A will enroll participants with advanced/metastatic solid tumors. Additional modules exploring other cancers may be added to the master protocol at a later date. Each module will be conducted in 2 parts: Part 1 (Dose Escalation) and Part 2 (Dose Expansion).

Conditions

• Advanced Solid Tumor
• RAF Mutation
• RAS Mutation
• NF1 Mutation
• Non-Small Cell Lung Cancer
• Pancreatic Ductal Adenocarcinoma
• Melanoma
• BRAF Gene Mutation
• CRAF Gene Mutation
• Castration-Resistant Prostate Cancer (CRPC)

Interventions

• DCC-3084

• In addition to the general exclusion criteria, participants will also be excluded based on the cohort-specific exclusion criteria
• Exclusion Criteria: Module A Part 2 Cohort Specific:
• Has known co-occurring mutation of KRAS, HRAS, NRAS, NF1, epidermal growth factor receptor, Phosphoinositide-3-kinase, catalytic, alpha polypeptide (PI3KCA), or Phosphatase and TENsin homolog deleted on chromosome 10 (PTEN)
