OV Precision: Study Examining the Benefit of a Tumor- and Patient-specific Cancer Therapy

Официальное название

OV PRECISION: A Randomized Controlled Swiss Trial Examining the Benefit of a Tumor- and Patient-specific Cancer Therapy in Ovarian Cancer.

Обзор

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

Подробное описание

Homologous recombination proficient (HRP) or HRD negative (HRDneg) Ovarian Cancer (OC) patients have a poor outcome equivalent to platinum-resistant patients (PFS 11.5 month). 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 scarce and 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 a 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).
