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

Condition(s) studied

Investigational drug(s) / intervention(s)

Treatment recommendation by molecular tumorboard (mTB) based on tumor profiling: The intervention studied is a treatment recommendation by a specialized molecular tumorboard (mTB). This recommendation is based on an MSR which is created by TP, i.e., molecular analysis of clinical specimens, obtained from the individual participant. TP, a technology platform of several precision-cancer profiling domains, combines and rates the most efficient drugs/ experimental treatments for an individual ovarian cancer patient independent of standard of care. 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.

Carboplatin / Paclitaxel Chemotherapy: 2 cycles of chemotherapy with carboplatin AUC5 3-weekly and paclitaxel 175 mg/m2 3-weekly or carboplatin AUC2 weekly and Paclitaxel 60-80mg/m2 weekly

Study summary

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.

Eligibility

Primary outcome measure(s)

• Focal Outcome Measure (FOM) 1 of pilot study: Proportion of patients for whom the molecular Tumor Board (mTB) considers a different treatment option — 2-3 weeks
  * 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)
• 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. — 2-3 weeks
  * 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.
• FOM 3 of pilot study: Investigation of different treatment decisions by the patient and the treating oncologist. — 4 weeks
  * 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.
• FOM 4 of pilot study: Preliminary estimate of the actual patient benefit of the intervention in terms of a number of patient-relevant outcomes. — 10 weeks
  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. * Quality of Life (QoL): Questionnaires EORTC QLQ-C30, EORTC QLQ-OV28 from V1 (baseline at diagnosis) until V9 (EOT), in both arms.
