Brief Summary:
This study will evaluate the safety and tolerability of oral TP-1454 in patients with advanced metastatic or progressive solid tumors, alone and in combination with Ipilimumab and Nivolumab.

Condition or disease Intervention/treatment Phase
Advanced Solid Tumor Drug: TP-1454 monotherapy Drug: TP-1454 combination therapy Phase 1

Detailed Description:

Primary Objective:

  • To establish the MTD and/or Recommended Phase 2 Dose (RP2D) of orally administered TP-1454 monotherapy in patients with advanced metastatic solid tumors
  • To establish the MTD and/or RP2D of orally administered TP-1454 in combination with ipilimumab and nivolumab in patients with advanced/metastatic solid tumors whom the investigator deems appropriate for treatment with the defined regimen

Secondary Objectives:

  • To establish the pharmacokinetic (PK) profile of orally administered TP-1454 alone and in combination with ipilimumab and nivolumab
  • To observe patients for any evidence of antitumor activity of TP 1454 alone and in combination with ipilimumab and nivolumab by objective radiographic assessment
  • To study the safety of oral TP-1454 administered as monotherapy and in combination with ipilimumab and nivolumab in patients with advanced/metastatic solid tumors whom the investigator deems appropriate for treatment with the defined regimen

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 44 participants
Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Intervention Model Description: Open label
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I, First-in-human, Open-label, Dose Escalation, Safety, Pharmacokinetic, and Pharmacodynamic Study of Oral TP 1454 Alone and in Combination With Ipilimumab and Nivolumab
Actual Study Start Date : July 8, 2020
Estimated Primary Completion Date : November 2022
Estimated Study Completion Date : December 2022

Arm Intervention/treatment
Experimental: Monotherapy
Drug: TP-1454 monotherapy
Flat dose once or twice daily, alone

Experimental: Combination Therapy
TP-1454, ipilimumab and nivolumab
Drug: TP-1454 combination therapy
Flat dose once or twice daily, in combination with ipilimumab and nivolumab

Primary Outcome Measures :
  1. Incidence of dose-limiting toxicities (DLTs) [ Time Frame: 28 months ]
    A DLT is defined as a drug-related toxicity that is observed to occur within the first 21 or 28 days of treatment depending on which arm the patient is enrolled in (monotherapy 28 days; combination 21 days).

  2. Determine maximum tolerated dose (MTD) [ Time Frame: 28 months ]
    MTD will be determined based upon toxicity grades which are defined by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v 5.0.

  3. Recommended Ph 2 dose of TP-1454 [ Time Frame: 28 months ]
    To establish the recommended Ph 2 dose (RP2D) for future studies with TP-1454. MTD, PK and PD data to be reviewed.

Secondary Outcome Measures :
  1. Determine antitumor activity of TP-1454. [ Time Frame: 28 months ]
    Objective radiographic assessment to be performed to determine antitumor activity by Response Evaluation Criteria in Solid Tumors (RECIST criteria v 1.1.
