-Summary

This is a phase II/III randomized controlled trial to evaluate efficacy of platinum-based chemotherapy vs conventionally prescribed non-platinum monochemotherapy in patients with platinum-resistant ovarian cancer

+Detailed description

Recurrent ovarian cancer (ROC) is usually subdivided to platinum-sensitive (platinum-free interval \[PFI\] ≥6 mo.) and platinum-resistant ovarian cancer \[PROC\] (PFI <6 mo.) subtypes. Prognosis for the latter group is dismal and current guidelines recommend treating these patients with non-platinum based chemotherapy. However, the evidence behind this is quite unconvincing and according to recent data patients with non-platinum refractory platinum-resistant ovarian cancer could derive benefit from platinum rechallenge. This trial is designed for head-to-head comparison of platinum and non-platinum therapy efficacy in treatment of platinum-resistant ovarian cancer.

+Arms and interventions

ArmTypeInterventionsDescription
Platinum-based chemotherapyExperimentalDrug: Platinum-Based DrugThis is an experimental arm of this study. Allowed therapeutic options: 1. Paclitaxel 60-80 mg/m2 + carboplatin area under curve (AUC) 2-2.7 d 1, 8, 15 every 3 or 4 weeks (Q3W or Q4W); 2. Gemcitabine 1000 mg/m2 d 1, 8 + cisplatin 75 mg/m2 1 every 3 weeks; 3. Doxorubicin 40-50 mg/m2 d 1 + carboplatin AUC5 or cisplatin 60-75 mg/m2 d 1 every 3 weeks; 4. Topotecan 0.75 mg/m2 d 1-3 + cisplatin 60-75 mg/m2 or carboplatin AUC 4-5 d 1 every 3 weeks; 5. Etoposide 100 mg once daily orally d 1-7 + cisplatin 60-75 mg/m2 d1 every 3 weeks. Up to 6 cycles of chemotherapy will be administered to study participants allocated to this arm.
Non-platinum monochemotherapyActive comparatorDrug: Conventional chemotherapyThis is a control arm of this study. Allowed therapeutic options: 1. Paclitaxel 60-80 mg/m2 weekly (or day 1, 8, 15 every 4 weeks schedule); 2. Gemcitabine 1000 mg/m2 d 1, 8, 15 every 4 weeks; 3. Doxorubicin 50-60 mg/m2 d 1 every 3 weeks; 4. Topotecan 1,2-1,5 mg/m2 d 1-5 every 3 weeks; 5. Etoposide 100 mg once daily orally d 1-10 every 3 weeks. Up to 6 cycles of chemotherapy will be administered to study participants allocated to this arm.
  • Platinum-Based Drug (Drug): Reintroduction of platinum-based chemotherapy
  • Conventional chemotherapy (Drug): Conventional chemotherapy

+Outcome measures

Primary outcomes

  • Objective response rate (RR) according to RECIST 1.1 criteria [0-18 weeks]: Primary outcome for Phase II part: response rate to treatment according to RECIST1.1 criteria. For patients without measurable disease Rustin criteria is allowed.
  • Overall survival defined as time from randomization to death from any reason; [1 year]: Primary outcome for Phase III part: 2. Overall survival defined as time from randomization to death from any reason

Secondary outcomes

  • Progression-free survival [12 months]: Progression-free survival (PFS) defined as time from randomization to disease progression according to RECIST 1.1 criteria or death from any reason;
  • Overall survival [12 months]: Overall survival defined as time from randomization to death from any reason (for Phase II part only);
  • Progression-free survival 2 (PFS2) [24 months]: PFS2 defined as time from randomization to second disease progression event according to RECIST 1.1 criteria or death from any reason;
  • Objective response rate (RR) according to RECIST 1.1 criteria [12 months]: Response rate to treatment according to RECIST1.1 criteria. For patients without measurable disease Rustin criteria is allowed (only for Phase II part).

* Platinum-free interval ≤12 months;
* Eastern Cooperative Oncology Group (ECOG) performance status ≤2;
* Response to penultimate platinum-based chemotherapy defined as partial or complete response assessed by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria or ≥50% reduction in CA-125 concentration for patients without measurable lesions;
* Not refractory to penultimate platinum-based chemotherapy regimen (ie, the disease did not progress during platinum-based chemotherapy and within ≤3 months after its completion);
* Patients received ≤3 lines of prior chemotherapy;
* No central nervous system (CNS) metastatic involvement;
* No severe and uncontrolled concomitant diseases;
* Adequate organ function:

  * Bone marrow - hemoglobin ≥ 90 g/l; Neutrophils ≥1,5x109/l; Platelets ≥75x109/l);
  * Renal - estimated creatinine clearance ≥50 ml/min (determined by Cockcroft-Gault equation);
  * Hepatic - alanine aminotransferase (ALaT) \& aspartate transaminase (ASaT) ≤3 upper limit of normal (ULN), total bilirubin ≤ 25 umol/l;
* Known BRCA1/2 mutation status as it will be used for stratification;
* Life expectancy >3 months;
* Patient is willingly consent to participate in the trial and signed informed consent form

Exclusion Criteria:

* Platinum-refractory ovarian cancer defined as disease progression during penultimate platinum-based chemotherapy or ≤3 month after its completion;
* No response to penultimate platinum-based chemotherapy;
* Mucinous, clear-cell or low-grade serous/endometrioid histology;
* >3 lines of prior therapy lines for advanced ovarian cancer (prior maintenance endocrine therapy or poly ADP ribose polymerase (PARP) inhibitors is allowed);
* Prior therapy with PARP-inhibitors and endocrine therapy as a treatment for progressive ovarian cancer;
* Platinum-free interval >12 months;
* Symptoms of bowel obstruction of any etiology;
