Brief Summary:

This is a Phase 1, multicenter, open-label, multiple-dose, dose-escalation and dose-expansion study to evaluate the safety, tolerability, PK, and pharmacodynamics of TTX-080 monotherapy in subjects with advanced or metastatic solid tumors known to express HLA-G.

This first-in-human (FIH) study has been designed to evaluate the safety, tolerability, and preliminary antitumor activity of TTX-080 as monotherapy in adults with unresectable or metastatic solid tumors known to express HLA-G.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A First-in-human, Phase 1 Study to Evaluate the Safety of TTX-080, an HLA-G Antagonist, in Subjects With Advanced Solid Tumors
Actual Study Start Date : July 14, 2020
Estimated Primary Completion Date : August 30, 2021
Estimated Study Completion Date : February 1, 2022


Arm Intervention/treatment
Experimental: Monotherapy Dose Escalation Drug: TTX-080
Variable dose (Q3W)




Primary Outcome Measures :
  1. Recommended Phase 2 Dose (RP2D) [ Time Frame: 1 cycle (each cycle is 21 days) ]
    To assess safety and tolerability of increasing dose levels of TTX-080 in successive cohorts of subjects with advanced solid tumors to identify the maximum tolerated dose (MTD) or maximum administered dose and select the recommended Phase 2 dose (RP2D)/schedule


Secondary Outcome Measures :
  1. Pharmacokinetics (PK) [ Time Frame: Through study completion, an average of 1 year ]
    Serum concentrations of TTX-080 will be tabulated

  2. Immunogenicity [ Time Frame: Through study completion, an average of 1 year ]
    Serum levels of antidrug antibody (ADA) against TTX-080

  3. Objective tumor response [ Time Frame: Through study completion, an average of 1 year ]
    Measure the proportion of subjects with ORR, DoR, and PFS
