Summary
The current standard of first-line chemotherapy in advanced ovarian cancer is the combination of carboplatin AUC 5mg/mL/min and paclitaxel 175 mg.m-². This combination is feasible in selected elderly patients such as those included in prospective trials. These trials, however, include a minority of the elderly population. In wider selection of patients >70 years old, the standard carboplatin-paclitaxel regimen has been shown to induce an excess of toxicity and premature treatment stopping. For elderly patients thought to be vulnerable and at high risk of toxicity with the standard 3-weekly carboplatin-paclitaxel regimen, other options are used in routine practice. One option is to delete paclitaxel and treat elderly patients with carboplatin as a single agent. An alternative is to use the carboplatin-paclitaxel regimen in a weekly schedule for both drugs such as reported by the MITO (Multicentre Italian Trial in Ovarian Cancer).

To date, there is no randomized trial which could give us some evidence of how to select patients who could benefit most of one or the other regimen described above. The 4th Ovarian Cancer Consensus Conference has indeed recognised the medical unmet need of adapted therapy for elderly patients with ovarian cancer and the necessity of additional research in this population.

Recently, GINECO has described a Geriatric Vulnerability Score (GVS) in a population of elderly patients with advanced ovarian cancer included in a specific multicenter phase II trial. The best proportional hazard model fitting for overall survival identified the following geriatric covariates score as being poor survival risk factors: ADL score <6, IADL score <25, HADS score >14, albuminemia <35g/L and , lymphopenia <1G/L. GVS is the sum of these risk factors for each patient. Using a cut off of 3, the GVS identified a group of patients at high risk of severe toxicity, early cessation of treatment, unplanned hospitalization and adverse outcomes.

This international multicentre randomized phase II trial will compare the success rate of delivering 6 courses of chemotherapy with evidence of efficacy and without premature termination for progression, death or unacceptable toxicity of three different chemotherapy regimens in a selected population of elderly patients with a GVS ≥ 3:

- Arm A: Paclitaxel 175mg/m²/3 hours, I.V. and carboplatin AUC 5, I.V. every 3 weeks

- Arm B: Carboplatin monotherapy AUC 5 or 6 every 3 weeks

- Arm C: Weekly paclitaxel 60 mg/m²/1 hour and weekly carboplatin AUC 2 (d1, d8, d15 every 4 weeks)

The total number of patients to be enrolled is 240, ie 22 in each arm (total = 66) at the first step, then 58 more by arm (total=174) after interim analysis.
