RAD-18-003

A phase 2, randomised, open label, multicentre study of an intraperitoneal α-emitting radionuclide therapy (Radspherin®) in patients with primary advanced high-grade serous or high-grade endometrioid epithelial ovarian, fallopian tube, or primary peritoneal cancer, with peritoneal metastasis that are homologous recombination proficient and scheduled to undergo neoadjuvant chemotherapy and interval debulking surgery

Treatment

This study consists of two different treatment options:

  • Arm A: interval debulking + Radspherin
  • Arm B: interval debulking


The patient will be randomly allocated to one of the treatment groups on a 2:1 ratio.

Treatment duration

Radspherin is given 2 days after the interval debulking via intraperitoneal in-dwelling catheter placed during surgery. 

Eligibility

Main inclusion criteria:

  • Patients with primary advanced high-grade serous or high-grade endometrioid epithelial ovarian, fallopian tube, or primary peritoneal cancer (FIGO Stage IIIB/C or IV)
  • Peritoneal and other metastases eligible for IDS to no residual tumour
  • Confirmed HRD proficient by Myriad MyChoice CDx testing
  • Completed 3 or 4 cycles of NACT with regress or stable disease on diagnostic imaging and assessed to be operable to R0

Main exclusion criteria:

  • Known somatic or germline BRCA1 or BRCA2 mutations or confirmed HRD deficient.
  • Suspicion of peritoneal leak, shunt, or otherwise suspected atypical target compartment pharmacokinetics, based on investigator's judgement, patient history and diagnostic images
  • Epithelial borderline tumours, ovarian clear cell carcinoma, mucinous ovarian carcinoma, malignant Brenner tumours, non-epithelial ovarian malignancies, carcinosarcoma and neuroendocrine tumours or recurrent ovarian cancer
  • Disease progression during 3 to 4 cycles of NACT

Disclaimer: This is an overview of the main in- and exclusion criteria which can also be found on clinicaltrials.gov (NCT06504147). Criteria might change during the course of the study due to amendments. Inclusion in the trial remains the responsibility of the principal investigator of the trial and will depend on patient eligibility and slot availability.
