Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved

Summary

This phase 3 trial tested a combination of two targeted drugs, alpelisib and olaparib, against standard chemotherapy in 358 women with a tough-to-treat type of ovarian cancer that had stopped responding to platinum-based chemotherapy. The study only included women without a BRCA gene mutation. Unfortunately, the trial was terminated early, so we don't have full results on whether the combination worked better than chemo.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
alpelisib and olaparib combination
What this could lead to
If successful, this could offer a new targeted therapy option for women with platinum-resistant ovarian cancer who do not have a BRCA mutation.
What could go wrong
The trial was terminated early, so results are limited. The combination may not prove better than standard chemotherapy, and side effects from the drugs could be significant.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Key Inclusion Criteria: * Participant has histologically confirmed diagnosis of high-grade serous or high-grade endometrioid ovarian cancer, fallopian tube cancer, or primary peritoneal cancer * Measurable disease, i.e., at least one measurable lesion per RECIST 1.1 criteria (a lesion at a previously irradiated site may only be counted as a target lesion if there is clear sign of progression since the irradiation) * If no measurable disease is present, the disease should be assessable by Gynecologic Cancer Intergroup criteria (GCIC) for CA-125 * Participant has no germline BRCA1/2 mutation as determined by an FDA-approved assay * Participant has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 * Participant has platinum-resistant (progression within one to six months after completing platinum-based therapy) or platinum refractory disease (progression during treatment or within 4 weeks after the last dose), where platinum-based therapy is not an option, according to the GCIG 5th Ovarian Cancer Consensus Conference definitions (Wilson et al 2016). The platinum-based chemotherapy regimen does not necessarily need to be the last regimen the participant received prior to study entry * Participant must have received at least one but no more than three prior systemic treatment regimens and for whom single-agent chemotherapy is appropriate as the next line of treatment * Participant has received prior bevacizumab or is not eligible to receive bevacizumab due to medical reasons. Key Exclusion Criteria: * Participant has received prior treatment with any PI3K, mTOR or AKT inhibitor * Participant is concurrently using other anti-cancer therapy * Participant is in a state of small or large bowel obstruction or has other impairment of gastrointestinal (GI) function or GI disease * Participant has had surgery within 14 days prior to starting study drug or has not recovered from major adverse effects * Participant has not recovered from all toxicities related to prior anticancer therapies to baseline or NCI CTCAE Version 4.03 Grade ≤1. Exception to this criterion: participants with any grade of alopecia are allowed to enter the study * Participant has an established diagnosis of diabetes mellitus type I or uncontrolled type II based on fasting plasma glucose and HbA1c * Participants with liver impairment and Child Pugh score B or C * Participant has received radiotherapy ≤ 4 weeks or limited field radiation for palliation ≤ 2 weeks prior to randomization, and who has not recovered to baseline, grade 1 or better from related adverse effects of such therapy (with the exception of alopecia) * Participant has a known hypersensitivity to any of the study drugs or excipients * Participant has a history of myelodysplastic syndrome or acute myeloid leukemia, or presents clinical and/ or laboratory features suggestive thereof. Other inclusion/exclusion criteria may apply
