Study Details

Study Description

Brief Summary

The purpose of this study is to determine the maximum tolerated dose of Debio 0932 when administered orally, every-other-day or daily during the first 30 days, in patients with solid tumours or lymphoma.

Condition or Disease	Intervention/Treatment	Phase
Cancer Neoplasms Solid Tumors Lymphoma	Drug: Debio 0932	Phase 1

Detailed Description

This is an open-label, non-randomised, dose-escalation phase I, pharmacokinetic and pharmacodynamic study in patients with advanced and/or refractory malignancies (solid tumours or lymphoma), to determine the maximum tolerated doses (MTD) of Debio 0932 administered orally every-other-day (schedule A) or every day (schedule B) and to assess its safety profile, pharmakokinetic, antitumor activity and pharmacodynamic biomarkers.

Increments used in dose escalation will be determined according to the maximum grade of treatment-related adverse events observed during the first 30-day treatment period of each schedule in the previous in the preceding dose level Once reaching the recommended dose (RD) for each schedule, up to 40 additional patients will be enrolled and treated at the RD of the retained schedule, as part of an expansion phase.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: schedule A Debio 0932 will be administered orally to sequential escalating dose cohorts, as an every-other-day schedule. Each dose level (DL) for each schedule will be determined according to the maximum grade of treatment-related AEs observed during the first 30 days treatment period (DLT period) in the previous DL. Dose-escalation could be undertaken only after a minimum of 3 (or 6 in case of DLT) patients have been followed up and evaluated for at least 1 DLT period.	Drug: Debio 0932 Gelatin capsules of 2 dosage strengths (25 mg or 100 mg) The maximum dose will depend on the number of dose levels necessary to determine the MTD. In both schedules the study treatment will be continued, until one of the study treatment discontinuation criteria is met.
Experimental: schedule B Debio 0932 will be administered orally to sequential escalating dose cohorts, as a daily schedule. Each dose level (DL) for each schedule will be determined according to the maximum grade of treatment-related AEs observed during the first 30 days treatment period (DLT period) in the previous DL. Dose-escalation could be undertaken only after a minimum of 3 (or 6 in case of DLT) patients have been followed up and evaluated for at least 1 DLT period.	Drug: Debio 0932 Gelatin capsules of 2 dosage strengths (25 mg or 100 mg) The maximum dose will depend on the number of dose levels necessary to determine the MTD. In both schedules the study treatment will be continued, until one of the study treatment discontinuation criteria is met.

Intervention/Treatment

Experimental: schedule A

Debio 0932 will be administered orally to sequential escalating dose cohorts, as an every-other-day schedule. Each dose level (DL) for each schedule will be determined according to the maximum grade of treatment-related AEs observed during the first 30 days treatment period (DLT period) in the previous DL. Dose-escalation could be undertaken only after a minimum of 3 (or 6 in case of DLT) patients have been followed up and evaluated for at least 1 DLT period.

Drug: Debio 0932

Gelatin capsules of 2 dosage strengths (25 mg or 100 mg) The maximum dose will depend on the number of dose levels necessary to determine the MTD. In both schedules the study treatment will be continued, until one of the study treatment discontinuation criteria is met.

Experimental: schedule B

Debio 0932 will be administered orally to sequential escalating dose cohorts, as a daily schedule. Each dose level (DL) for each schedule will be determined according to the maximum grade of treatment-related AEs observed during the first 30 days treatment period (DLT period) in the previous DL. Dose-escalation could be undertaken only after a minimum of 3 (or 6 in case of DLT) patients have been followed up and evaluated for at least 1 DLT period.

Outcome Measures

Primary Outcome Measures

Occurence of DLTs for both schedules [30 days]
Occurrence of dose-limiting toxicities (DLTs) for both schedule A and schedule B

Secondary Outcome Measures

Incidence of AEs, change in safety and efficacy parameters [Duration of study]
Incidence of Adverse Events (AEs), Serious Adverse Events (SAEs), laboratory abnormalities, treatment discontinuations due to AEs for both schedules and expansion phase, change in 12-lead ECG (RR, PR, QRS, QT and QTcF intervals), rate of confirmed response, duration of response and disease control, pharmacodynamic biomarkers and drug pharmacokinetic parameters.
