Clinical Trial Summary

The long-term goal of this research project is to demonstrate whether HRD negative (HPR) patients benefit when additional multimodal biological tumor information is incorporated into the molecular tumor board (mTB) treatment recommendation process.

Description:

Homologous recombination proficient (HRP) or HRD negative (HRDneg) Ovarain Cancer (OC) patients have a poor outcome equivalent to platinum-resistant patients (PFS 11.5 months;.Given standard of care chemotherapy is not ideal for 50% of EOC and this patient population urgently needs alternative treatment options tailored to their individual tumor profile. Treatment options for the heterogeneous HRDneg patient group are scarceand mainly focus on symptom control and palliation, delaying time to symptomatic progression, and improving QoL. Therefore, trials at initial diagnosis, when the patient can still be cured and is treatment naïve, are urgently needed. The intervention studied is a personalized treatment recommendation by a specialized molecular tumorboard. This recommendation is based on a Molecular summary report (MSR) which is created by multi-modal Tumor Profiling (TP) , i.e., molecular analysis of clinical specimens, obtained from the individual participant. TP, a technology platform of several precision-cancer profiling domains established by the TPC (= Tumor Profiler Center, Switzerland), It combines and rates the most efficient drugs/ experimental treatments for an individual ovarian cancer patient independent of standard of care (SOC). The usability in clinical practice of this recommendation will be tested. It should support the clinical decision of the treating oncologists and patients to choose the best possible therapy for the individual patient. Treatment recommendations on the most appropriate molecular-based treatment for the individual patient are formulated based on the expertise and experience of the mTB board members. Additionally, a MSR from validated TP technology platform can serve as further guidance in the tumorboard. However, the final decision on initial treatment remains at the discretion of the treating physician and the patient. OV Precision is a multicenter randomized (1:1) controlled trial comparing a personalized treatment recommendation at the discretion of the treating physician in agreement with the patient versus SOC without receiving a mTB recommendation. The study will be divided into two phases: an initial diagnostic phase, in which presumed eligible patients will be recruited into the study, HRD status will be determined, and tumor profiling will be performed in HRDneg patients with a confirmed diagnosis. Eligible patients will be randomized and treated according to their group allocation in the second phase (treatment phase). The study duration is planned for 3 years including analysis: Two years of recruitment (starting from 09/2024), final analysis of the focal endpoints and end of the study 10 weeks after inclusion of the last patient (12/2026). Study analysis and publication should be completed approximately one year later (12/2027).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Focal Outcome Measure (FOM) 1 of pilot study: Proportion of patients for whom the molecular Tumor Board (mTB) considers a different treatment option	Number (proportion) of cases in which the Tumor Profiling (TP) was able to generate a conclusive Molecular Summary Report (MSR); Number (proportion) of cases in which the mTB considers the MSR as useful support for making a treatment recommendation on a scale from zero (not useful at all) to five (very useful)	2-3 weeks
Primary	FOM 2 of pilot study: Investigation whether the treating oncologist feels better supported by the mTB recommendation considers the additional biological tumor information than by the standard of care where such information is not considered.	Number (proportion) of cases in which the treating physician considers the mTB recommendation as useful for making a final treatment decision on a scale from zero (not useful at all) to five (very useful).; Definition of molecular results from TP that cannot be used for clinical decision making.; Definition of an algorithm for the decision process from MSR to treatment recommendation.	2-3 weeks
Primary	FOM 3 of pilot study: Investigation of different treatment decisions by the patient and the treating oncologist.	Number of therapy adaptations in the exploratory arm based on the MSR.; Number (proportion) of cases with therapy adaptions with minor / major/ no change from SOC.; Number (proportion) of treatment recommendations by mTB which were followed by the doctor and patient in the window of opportunity.; Number (proportion) of treatment recommendations by mTB which were continued by the doctor and patient after the trial and after finishing SOC.; Number (proportion) of treatment recommendations by mTB which were not followed by the doctor and patient in the window of opportunity due to restrictions.; Differences in hypothetical treatment costs between SOC and exploratory arm.	4 weeks
Primary	FOM 4 of pilot study: Preliminary estimate of the actual patient benefit of the intervention in terms of a number of patient-relevant outcomes.	The difference in proportions of responders between the standard of care and experimental arm after interval debulking surgery or biopsy at second specimen collection time point (week 10). A patient is classified as a responder if at least one of the two conditions is met: The Chemotherapy Response Score (CRS) is larger than or equal to 2 or the CA125 KELIM score is larger than or equal to 1.; Note A : The three-tired CRS ranges from 1 (no or minimal tumor response) to 3 (total or near-total tumor response) .; Note B: The tumormarker CA125 level decline (= CA125 KELIM ) over at least 3 timepoints can give an indication of therapy response. A favourable KELIM score = 1.0,Unfavorable KELIM score < 1.; Symptoms measured by MOST- S26 questionnaire from V1 (baseline at diagnosis) until V9 (EOT), in both arms.; Qualitiy of Life (QoL): Questionnaires EORTC QLQ-C30, EORTC QLQ-OV28 from V1 (baseline at diagnosis) until V9 (EOT), in both arms.	10 weeks
