What the trial was testing
The ARIEL4 enrolled 349 patients with ovarian cancer. The study was sponsored by pharmaand GmbH and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was a large trial designed to confirm whether the treatment works well enough for wider use. 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
Women on rucaparib went 7.4 months without cancer growth versus 5.7 months on chemotherapy.
The Lancet. Oncology · 2022 · NCT02855944
These findings — that time before cancer grew on rucaparib compared to chemotherapy — were published in the The Lancet. Oncology and represent the headline result of the study.
Researchers tracked outcomes across 349 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
Rucaparib is FDA-approved for ovarian cancer with BRCA mutations. If you have relapsed ovarian cancer and carry a BRCA1 or BRCA2 mutation, talk to your oncologist about whether rucaparib is right for you. It may offer more time before cancer progresses compared to chemotherapy.
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.

A Study of Hansoh (HS)-10502 in Patients With Advanced Solid Tumors
HS-10502 is a Poly(ADP-ribose) polymerase 1 (PARP1)-specific selective inhibitor. The purpose if this study is to assess the safety, tolerability, pharmacokinetics (PK), and efficacy of HS-10502 in subjects with homologous recombination repair (HRR) gene mutant or homologous recombination deficiency (HRD) positive advanced solid tumors.
A Study to Test the Safety, Tolerability and Effect of ZI-MA4-1 for Patients With Locally Advanced or Metastatic Solid Malignancies
This study will recruit patients with the following cancer indications: ovarian cancer, squamous non-small cell lung cancer, synovial sarcoma and head and neck cancer, with inoperable locally advanced or metastatic solid tumours. Currently, these patients have a poor prognosis and a relatively short overall survival. There is a lack of meaningful, effective therapies available that improve the outcome for these patients. The treatment being investigated in this study is ZIMA4-1, an allogeneic cell therapy product. This is the first time ZI-MA4-1 will be administered to humans. The study is planned to consist of two parts (A and B). Part A includes up to four dose escalation cohorts and aims to identify the maximum tolerated dose of ZI-MA4-1 and give insight into the recommended Phase 2 dose (RP2D). Part B consists of an expansion cohort and is designed to further evaluate the RP2D identified in Part A across one or more indications. The study procedures and eligibility criteria will be the same for participants in Parts A and B, except for the dose level of ZI-MA4-1.
