What the trial was testing
The GOG 281/LOGS enrolled 260 patients with ovarian cancer. The study was sponsored by National Cancer Institute (NCI) and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was mid-stage testing (phase 2/3). Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
Patients taking trametinib went 13 months without cancer progression versus 7 months with standard treatments.
Lancet (London, England) · 2022 · NCT02101788
These findings — that time without cancer worsening nearly doubled with trametinib — were published in the Lancet (London, England) and represent the headline result of the study.
Researchers tracked outcomes across 260 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with ovarian cancer, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Trametinib is FDA-approved for this type of ovarian cancer and is now considered a standard treatment option. If you have low-grade serous ovarian cancer that has come back after prior treatment, ask your oncologist whether trametinib might be right for you.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

ORACLE: Observation of ResiduAl Cancer With Liquid Biopsy Evaluation
The purpose of ORACLE is to demonstrate the ability of a novel ctDNA assay developed by Guardant Health to detect recurrence in individuals treated for early-stage solid tumors. It is necessary that ctDNA test results are linked to clinical outcomes in order to demonstrate clinical validity for recurrence detection and explore its value in a healthcare environment subject to cost containment.
