What is being measured
The primary outcome is the main question the study is designed to answer.
Part A: Number of Participants With Dose-limiting Toxicities (DLTs)
DLT: any of following treatment-emergent adverse events (TEAEs) as per NCI CTCAE Grade V5.0 Criteria (Grades 1=mild, 2=moderate, 3=severe and 4 or 5= life-threatening/fatal outcomes) which are possibly, probably or definitely related to combination treatment and occurring in Cycle 1 (1 Cycle=28 days): Any Grade 4 or 5 hematologic toxicity, clinical or laboratory non-hematologic toxicity; febrile neutropenia any grade, Grade 3 thrombocytopenia if associated with bleeding or requiring platelet transfusion; Grade 2; Grade 3 and any other Grade 3 non-hematologic, treatment-related clinical toxicity lasting ≥3 days; delay of >2 weeks due to drug-related toxicity in initiating Cycle 2; unable to complete at least 70% of the scheduled treatment (>six Debio 1143 skipped doses in Cycle 1) due to treatment-related toxicity; required dose reduction in Cycle 1 or on Cycle 2 Day 1 or requirement for treatment withdrawal due to treatment-related toxicity (even if not meeting other DLT criteria).
Measured: Part A: Cycle 1 (28 days)
Part B: Confirmed Objective Response Rate (ORR)
ORR was determined per response evaluation criteria in solid tumors (RECIST) v1.1 and/or gynecologic cancer intergroup (GCIG) criteria (for Cohort 4). ORR was calculated as the percentage of participants with a confirmed objective response. A confirmed objective response is a confirmed best overall response of partial response (PR) or complete response (CR) recorded after the start of study treatment until disease progression/recurrence was documented, a new systemic anti-cancer therapy was started or analysis cut-off, whichever occurred first. CR is defined by the disappearance of all target lesions and reduction of any pathological lymph nodes in short axis to <10 millimeters (mm). PR is defined by at least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum diameter.
Measured: Part B: From the start of study treatment until disease progression/recurrence was documented, a new systemic anti-cancer therapy was started or analysis cut-off, whichever occurred first (up to approximately 2.05 years)

An adverse event (AE) is any untoward medical occurrence in a clinical trial participant administered a medicinal product that does not necessarily have a causal relationship with this treatment. A TEAE is any new, related or non-related, undesirable medical occurrence or change of an existing condition in a participant that occurs during the treatment-emergent period, starting or worsening on or after the first study drug administration and up to 5 months after last nivolumab infusion, or the earliest date of new anticancer therapy - 1 day, whichever occurs first. An SAE is defined as any untoward medical occurrence that at any dose results in death; is life-threatening (i.e., puts the participant at immediate risk of death); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect, or is otherwise medically significant.
Measured: From the first study drug administration and up to 5 months after last nivolumab infusion, or the earliest date of new anticancer therapy -1 day, whichever occurs first (up to approximately 2.08 years in Part A and 2.05 years in Part B)

Primary outcome
Part A: Number of Participants With Dose-limiting Toxicities (DLTs)
Time frame: Part A: Cycle 1 (28 days)
DLT: any of following treatment-emergent adverse events (TEAEs) as per NCI CTCAE Grade V5.0 Criteria (Grades 1=mild, 2=moderate, 3=severe and 4 or 5= life-threatening/fatal outcomes) which are possibly, probably or definitely related to combination treatment and occurring in Cycle 1 (1 Cycle=28 days): Any Grade 4 or 5 hematologic toxicity, clinical or laboratory non-hematologic toxicity; febrile neutropenia any grade, Grade 3 thrombocytopenia if associated with bleeding or requiring platelet transfusion; Grade 2; Grade 3 and any other Grade 3 non-hematologic, treatment-related clinical toxicity lasting ≥3 days; delay of >2 weeks due to drug-related toxicity in initiating Cycle 2; unable to complete at least 70% of the scheduled treatment (>six Debio 1143 skipped doses in Cycle 1) due to treatment-related toxicity; required dose reduction in Cycle 1 or on Cycle 2 Day 1 or requirement for treatment withdrawal due to treatment-related toxicity (even if not meeting other DLT criteria).
Part B: Confirmed Objective Response Rate (ORR)
Time frame: Part B: From the start of study treatment until disease progression/recurrence was documented, a new systemic anti-cancer therapy was started or analysis cut-off, whichever occurred first (up to approximately 2.05 years)
ORR was determined per response evaluation criteria in solid tumors (RECIST) v1.1 and/or gynecologic cancer intergroup (GCIG) criteria (for Cohort 4). ORR was calculated as the percentage of participants with a confirmed objective response. A confirmed objective response is a confirmed best overall response of partial response (PR) or complete response (CR) recorded after the start of study treatment until disease progression/recurrence was documented, a new systemic anti-cancer therapy was started or analysis cut-off, whichever occurred first. CR is defined by the disappearance of all target lesions and reduction of any pathological lymph nodes in short axis to <10 millimeters (mm). PR is defined by at least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum diameter.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 17 sites in United States, France, Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 12 Jun 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Part A: Number of Participants With Dose-limiting Toxicities (DLTs) (time frame: Part A: Cycle 1 (28 days)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2023; AzTrials last refreshed its copy on 7 Nov 2026.
