Phase 1 study aimed at defining the dosage of Debio 0123 as monotherapy in adult patients with advanced solid tumors, followed by an expansion phase to evaluate safety and preliminary antitumor activity
Résumé de l'étude
This is a phase 1 study in which both the physician and the patient will know the dosage used of the investigational drug. Various hospitals will be involved in the study, which consists of 2 parts: • Part 1: dose escalation of Debio 0123 administered orally in repeated doses to determine the maximum tolerated dose and/or the recommended dose for phase 2 in patients with advanced solid tumors that have recurred or progressed after prior therapy and/or for whom no standard therapy with demonstrated benefit is available. Patients will receive Debio 0123 once daily at an initial dose of 30 mg. • Part 2: will begin once the maximum tolerated dose and/or the recommended dose for phase 2 has been determined and will involve the treatment of different tumors. This part will enroll patients who have progressed or have had a recurrence of 1 of the types of tumors specified below after standard therapy or for whom, in the opinion of the investigator, no effective standard therapy is available: - Arm A: uterine cancer - Arm B: ovarian, fallopian tube, and peritoneal cancer - Arm C: renal cell carcinoma, pancreatic cancer, or breast cancer. Patients with other types of solid tumors may be eligible upon documented agreement between Debiopharm and the investigator. During the study, a treatment cycle corresponds to 21 days, and tumor assessments must be performed until disease progression. For patients who discontinue study treatment, efficacy checks will include tumor assessments until disease progression or the start of a new antitumor treatment.

Intervention étudiée
The main interventions being examined are:
During the dose escalation in Part 1
• Determine the maximum tolerated dose and/or the recommended dose for phase 2 of Debio 0123 when administered to patients with advanced solid tumors that have recurred or progressed after prior therapy and/or for whom no standard therapy with demonstrated benefit is available.
During the expansion in Part 2
• Study the safety and tolerability of Debio 0123 in each arm and overall when administered at the recommended dose for phase 2 determined during the dose escalation phase (Part 1) of the study.
• Evaluate the antitumor activity of Debio 0123 when administered to patients in each arm.

Maladie en cours d'investigation
Debiopharm International SA is studying new treatments for locally advanced or metastatic solid tumors that have recurred or progressed following prior treatments and/or for which no cure is available. The goal is also to understand whether the investigational drug is effective, tolerated, and safe for use. The cell cycle is a process that our body controls through a sophisticated system. When the body's cells divide, the genetic material (DNA) is also duplicated, and it is very important that the repair of damaged DNA occurs before cell division. For this to happen, our body has a series of checks that are activated through certain specific molecules called proteins. Cells commonly use these proteins to have time to repair DNA damage in tumor cells, avoiding entering division with too much DNA damage. The drug under investigation, Debio 0123, prevents tumor cells from repairing their damaged DNA. In this way, it is believed that it may help kill tumor cells and reduce tumor size.
(BASEC)
Only dose escalation in Part 1 • Histologically or cytologically confirmed locally advanced or metastatic solid tumors. • Measurable or non-measurable disease according to RECIST version 1.1 criteria. • Disease progression during or after standard therapy and/or disease for which no standard therapy with proven benefit is available. Only expansion in Part 2 • Measurable disease according to RECIST version 1.1 criteria for each arm • Patients (≥18 years) who have progressed or have had a recurrence of one of the types of tumors specified in the study arms after standard therapy according to RECIST version 1.1, or for whom, in the opinion of the investigator, no effective standard therapy is available: • Arm A: - Histologically or cytologically confirmed serous uterine carcinoma (USC) that has recurred or progressed after at least 1 prior line of platinum-based therapy for the management of advanced or metastatic disease. Chemotherapy administered only in combination with primary RT as a radiosensitizer should not be considered as a systemic regimen. There is no restriction on the number of prior lines of therapy a patient may have received previously. Patients with microsatellite instability-high/mismatch repair deficiency (MSI-H/MMR-D) should have received prior PD1/PDL1 therapy or be ineligible for such therapy. • Arm B: - Histologically or cytologically confirmed epithelial ovarian cancer (EOC), recurrent, high-grade (serous, endometrioid, or clear cell), primary peritoneal cancer, or fallopian tube cancer. - Patients must have progressed after at least 1 prior platinum-based therapy for advanced/metastatic disease. Therapy with a poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) inhibitor is allowed. Patients may be platinum-resistant (defined as progression within 6 months of completing their most recent platinum-based chemotherapy regimen) or platinum-sensitive (defined as progression > 6 months after the end of their platinum-based chemotherapy). Platinum-based therapy should not be the last treatment before entering the study. Note: Patients with platinum-refractory disease (progression during platinum-containing therapy) are not eligible for Arm B of Part 2. • Arm C: - Histologically or cytologically confirmed renal carcinoma, breast cancer, or pancreatic cancer, locally advanced or metastatic. Dose escalation in Part 1 and expansion in Part 2 • Tumor accessible for biopsy and patient willing to undergo a tumor biopsy, unless an archival tumor sample is available. • Availability and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures. • Life expectancy of at least 3 months, in the investigator's best judgment. • Adequate bone marrow, liver, kidney function, and blood coagulation status. • Willingness to use highly effective contraceptive methods.
