Description

Summary

This study is a Phase 1/2, open-label, dose-escalation study with a consecutive parallel-group efficacy expansion study, designed to determine the safety, tolerability, PK, pharmacodynamics, and preliminary anti-tumor activity of DF6002 as monotherapy and in combination with nivolumab.

Official Title

A Phase 1/2, First-In-Human, Multi-Part, Open-Label, Multiple-Ascending Dose Study to Investigate the Safety, Tolerability, Pharmacokinetics, Biological, and Clinical Activity of DF6002 as a Monotherapy and in Combination With Nivolumab in Patients With Locally Advanced or Metastatic Solid Tumors, and Expansion in Selected Indications

Details

This study is a Phase 1/2, open-label, dose-escalation study with a consecutive parallel-group efficacy expansion study, designed to determine the safety, tolerability, PK, pharmacodynamics, and preliminary anti-tumor activity of DF6002 as monotherapy and in combination with nivolumab. The study consists of 3 parts: Phase 1: Dose-escalation as a monotherapy using a 3+3 design, with Phase 1 Cohort Expansion. Phase 1b: Dose-escalation as a combination with nivolumab using a 3+3 design, with Phase 1b Cohort Expansion. Phase 2: Efficacy Expansion using a group sequential design. In Phase 2, DF6002 will be evaluated as a monotherapy in the following indications: Cohort 2A: Advanced (unresectable or metastatic) melanoma. Cohort 2B: Advanced (unresectable or metastatic) non-small cell lung cancer (NSCLC). In Phase 2, DF6002 will be evaluated in combination with nivolumab in the following indication: Cohort 2C: Advanced (unresectable or metastatic) melanoma. Cohort 2D: Advanced (unresectable or metastatic) NSCLC. In each study phase, patients will receive DF6002 on Day 1 every 4 weeks (Q4W). Patients will receive DF6002 until confirmed progressive disease (PD), unacceptable toxicity (ie, dose-limiting toxicity [DLT]), or any reason for withdrawal from the study or Investigational Medicinal Product (IMP) occurs.

Additional Phase 1 Monotherapy and Phase 1b Combination With Nivolumab Expansion Inclusion

Criteria:

  1. Has one of the following tumor types: melanoma, non-small cell lung cancer, or triple negative breast cancer

Expansion Inclusion Criteria specific to Melanoma:

  1. Histologically confirmed, unresectable Stage III or Stage IV melanoma, as specified in the American Joint Committee on Cancer staging system.
  2. Participants with ocular or uveal melanoma are ineligible.
  3. PD-L1 status must be documented if available.
  4. BRAF (V600) mutation status must be known. Both BRAF-mutated and wild type participants are permitted in this cohort.
  5. BRAF-mutated participants must have been treated with approved targeted therapies.
  6. Must have documented progressive or recurrent disease on or after discontinuation of anti-PD-(L)1 therapy (administered as monotherapy or as part of a combination) as per

RECIST 1.1 criteria:

  1. Participants who received anti-PD-(L)1 in the adjuvant setting must have documented progressive or recurrent disease on or within 6 months of discontinuation of anti-PD-(L)1 therapy (administered as monotherapy or as part of a combination) as per RECIST 1.1 criteria.

Expansion Inclusion Criteria specific to NSCLC:

  1. Histologically confirmed NSCLC meeting stage criteria for stage IIIB, stage IV, or recurrent disease.
  2. Participants must have recurrent or progressive disease during or after platinum doublet-based chemotherapy or at least two prior lines of systemic therapy for advanced or metastatic disease OR Must have recurrent or progressive disease within 6 months after completing platinum-based chemotherapy for local disease.
  3. Participants must have received and progressed on or after anti-PD-(L)1 therapy, if available.
  4. Status for actionable mutations (e.g., EGFR, ALK, ROS1, RET, etc.) must be known (when testing is available as per country/region standard of care practices); participants with actionable mutations must have received and progressed on, have been intolerant to, or not be a candidate for, standard tyrosine kinase inhibitors (as available per country/region standard of care practices).

Expansion Inclusion Criteria specific to TNBC:

  1. Histologically confirmed unresectable, locally advanced or metastatic triple negative breast cancer.PD-L1 status, HER2-negative, estrogen receptor-negative, and progesterone receptor-negative status must be evaluated by local institutions before enrolment per guidelines of the American Society of Clinical Oncology and the College of American Pathologists.
