Brief Summary:
CA-170 is a rationally designed and orally available, small molecule that directly targets the Programmed death-ligands 1 and 2 (PD-L1/PD-L2), and V-domain Ig suppressor of T cell activation (VISTA) immune checkpoints and results in activation of T cell proliferation and cytokine production. This is a multi-center, open-label, Phase 1 trial of orally administered CA-170 in adult patients with advanced solid tumors or lymphomas who have progressed or are non-responsive to available therapies and for which no standard therapy exists.

Condition or disease Intervention/treatment Phase
Advanced Solid Tumors or Lymphomas Drug: CA-170 Phase 1

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 300 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1, Open-Label, Dose Escalation and Dose Expansion Trial Evaluating the Safety, Pharmacokinetics, Pharmacodynamics, and Clinical Effects of Orally Administered CA-170 in Patients With Advanced Tumors and Lymphomas
Study Start Date : May 2016
Estimated Primary Completion Date : January 2019
Estimated Study Completion Date : January 2020

Arm Intervention/treatment
Experimental: CA-170
Taken orally in a once or twice daily schedule.
Drug: CA-170

Dose escalation stage (Phase 1a) accelerated titration and standard 3+3 dose escalation in patients with advanced solid tumor or lymphoma.

Dose expansion stage (Phase 1b) in patients with tumors that are shown to be responsive to anti-PD-1 or anti-PD-L1 checkpoint inhibitors and/or in tumor types known to express PD-L1 or VISTA, including but not limited to: mesothelioma, melanoma, non-small cell lung cancer, renal cell carcinoma, Hodgkin lymphoma, triple negative breast cancer, head and neck cancer, colorectal cancer, gastric cancer, bladder cancer, and ovarian cancer.

Primary Outcome Measures :
  1. The number of patients with a dose-limiting toxicity (DLT) in the first treatment cycle [ Time Frame: Approximately 24 months ]
  2. Maximum tolerated dose (MTD) of CA-170 [ Time Frame: Approximately 24 months ]
  3. Recommended Phase 2 Dose (RP2D) of CA-170 [ Time Frame: Approximately 24 months ]

Secondary Outcome Measures :
  1. Pharmacokinetic (PK) Profile of CA-170 [ Time Frame: From Day 1 of Cycle 1(each cycle is 21 days) ]
    Maximum Concentration (Cmax)

  2. Pharmacokinetic (PK) Profile of CA-170 [ Time Frame: From Day 1 of Cycle 1(each cycle is 21 days) ]
    Area Under the Curve (AUC)

  3. Preliminary Anti-tumor Activity of CA-170 based on RECIST and Immune Related Response Criterion (irRC) for Solid Tumors or Cheson for Lymphoma [ Time Frame: 36 months ]
