Study of PF-06940434 in Patients With Advanced or Metastatic Solid Tumors.

Study summary

Open-label, multi-center, non-randomized, multiple dose, safety, tolerability, pharmacokinetic, and pharmacodynamics and clinical activity study of PF-06940434 (Integrin alpha-V/beta-8 Antagonist) in patients with SCCHN (Squamous Cell Carcinoma of the Head and Neck), renal cell carcinoma (RCC - clear cell and papillary), ovarian, gastric, esophageal, esophageal (adeno and squamous), lung squamous cell, pancreatic and biliary duct, endometrial, melanoma and urothelial tumors. This study contains two parts, single agent dose escalation (Part 1A), dose finding of PF 06940434 in combination with anti-PD-1 (Part 1B) and dose expansion (Part 2). Part 2 Dose Combination Expansion will enroll participants into 3 cohorts at doses determined from Part 1B in order to further evaluate the safety of PF-06940434 in combination with anti-PD-1.

Who may be able to participate

The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.

Requirements people may need to meetInclusion criteria
  • \- Histological or cytological diagnosis of SCCHN, RCC (clear cell and papillary cell), ovarian, gastric, esophageal (adeno and squamous), lung squamous cell, pancreatic and biliary duct, endometrial, melanoma, or urothelial cancer. Part 2:
  • Arm A SCCHN:
  • Primary tumor location of the oral cavity, oropharynx, hypopharynx or larynx.
  • PDL-1 expression positive and CPS ≥1. No prior systemic therapy administered in the recurrent or metastatic setting (except for systemic therapy given as part of a multimodal treatment for locally advanced disease).
  • Arm B RCC (clear cell):
  • 1 or 2 prior lines of therapy including PD-L1/PD-1 immunotherapy in combination or sequentially with antiangiogenic directed treatment
  • Adequate bone marrow, kidney and liver function.
  • Performance status of 0 or 1.
Reasons someone may not be able to joinExclusion criteria
  • Participant disease status is suitable for local therapy administered with curative intent.
  • Hypertension that cannot be controlled by medications.
  • Active or prior autoimmune disease
