Incidence of Dose Limiting Toxicities (DLTs) During Dose Escalation Phase Primary · First cycle of 21 days

The incidence of DLTs was assessed based on the number of participants who experienced at least one dose-limiting toxicity (DLT) during the Dose Escalation phase, which was used to estimate the maximum tolerated dose (MTD). A DLT was defined as any protocol-specified adverse event that was possibly, probably, or definitely related to study drug combination and occurred during the first cycle of neoadjuvant chemotherapy, unless the event was clearly unrelated to the study therapy. Adverse events were assessed and graded according to NCI CTCAE v5.0.

Incidence of Dose-limiting Toxicities (DLTs) During Dose Expansion Phase Primary · First cycle of 21 days

The incidence of DLTs was assessed based on the number of participants who experienced at least one DLT during the Dose Expansion phase. This assessment was used to evaluate the feasibility of the treatment regimen at the estimated MTD, specially dose level 1. A DLT was defined as any protocol-specified adverse effect that was possibly, probably, or definitely related to study drug combination and occurred during the first cycle of neoadjuvant chemotherapy, unless the event was clearly unrelated to study therapy. Adverse events were assessed and graded according to NCI CTCAE v.5.0.

Incidence of Grade 3 or Higher Adverse Events (AEs) Primary · During treatment period and up to 90 days after the last dose of ipatasertib. The median duration of study treatment was 68 days with a range from 1 day to 90 days.

The incidence of grade 3 or higher AEs was assessed based on the number of participants who experienced at least one grade 3 or higher adverse event. Adverse events were graded and categorized according to NCI CTCAE v5.0.

Tumor Response Secondary · At 3 weeks (+/- 7 days) post Cycle 3 of the study treatment and prior to IDS.

Tumor response was assessed by RECIST 1.1 at 3 weeks (+/- 7 days) post Cycle 3 of the study treatment and prior to interval debulking surgery (IDS), and it could be repeated any other time if clinically indicated based on symptoms or physical signs suggestive of new or progressive disease.

Sponsor's own description

This phase I/IB trial tests the safety, side effects, and best dose of ipatasertib in combination with paclitaxel and carboplatin in treating patients with stage III or IV epithelial ovarian cancer. Ipatasertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Paclitaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Giving ipatasertib in combination with paclitaxel and carboplatin may lower the chance of the tumor growing or spreading for longer than the paclitaxel and carboplatin alone.
