Study Details

Study Description

Brief Summary

This study has two parts: Part 1 and Part 2. The purpose of this study in Part 1, Dose Escalation Part is to determine the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) of Debio 0123 as monotherapy with repeated dosing in adults with advanced solid tumors that recurred or progressed after prior therapy and/or for whom no standard therapy of proven benefit is available.

The purpose in Part 2, Expansion Part of this study, is to characterize the safety and tolerability of Debio 0123 when administered as monotherapy at the RP2D determined during the Dose Escalation Part 1 and to evaluate the preliminary anti-tumor activity of Debio 0123 when administered as monotherapy in participants with specific solid tumor types that recurred or progressed following prior lines of therapy.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Part 1: Dose Escalation

Participants will receive Debio 0123 orally in escalating dose cohorts during each 21-day treatment cycle until progression of disease, unacceptable toxicity, participant's withdrawal, or Investigator's decision, whichever occurs first.

Drug: Debio 0123
Debio 0123 orally during 21-day treatment cycles.

Experimental: Part 2: Expansion

Debio 0123 at the RP2D established in Part 1.

Drug: Debio 0123
Debio 0123 orally during 21-day treatment cycles.

Outcome Measures

Primary Outcome Measures

  1. Part 1: Maximum Tolerated Dose (MTD) as Determined by Percentage of Participants with Dose Limiting Toxicities (DLTs) [Cycle 1 (each cycle is 21 days)]

  2. Part 1: Recommended Phase 2 Dose (RP2D) as Determined by Percentage of Participants with DLTs and Cumulative Safety [Cycle 1 (each cycle is 21 days)]

  3. Part 2: Percentage of Participants with Serious Adverse Events (SAEs) [Up to 30 days after the last dose of study treatment (up to 13 months)]

  4. Part 2: Percentage of Participants with Treatment-Emergent Adverse Events (TEAEs) and Laboratory Abnormalities [Up to 30 days after the last dose of study treatment (up to 13 months)]

  5. Part 2: Percentage of Participants with Treatment Discontinuations and Treatment Modifications due to Adverse Events (AEs) and Laboratory Abnormalities [Up to end of study treatment (up to 12 months)]

  6. Part 2: Overall Response Rate (ORR) [From the start of study treatment until disease progression (up to 12 months)]

Secondary Outcome Measures

  1. Part 1: Percentage of Participants with SAEs [Up to 30 days after the last dose of study treatment (up to 13 months)]

  2. Part 1: Percentage of Participants with TEAEs and Laboratory Abnormalities [Up to 30 days after the last dose of study treatment (up to 13 months)]

  3. Part 1: Plasma Concentration of Debio 0123 [Pre-dose and at multiple time points up to 8 hours (h) on Day 1, Cycle 1 (each cycle is 21 days)]

    The pharmacokinetics (PK) of Debio-0123 will be evaluated in plasma.

  4. Parts 1 and 2: Anti-Tumor Activity as Assessed by Percentage of Participants with Tumor Response [Parts 1 and 2: Up to 12 months]
