Summary

The RAINBO umbrella program consists of four clinical trials investigating new adjuvant therapies in endometrial cancer patients. Eligible patients will be assigned to one of the four RAINBO trials based on the molecular profile of their cancer:

* p53 abnormal endometrial cancer patients to the p53abn-RED trial
* mismatch repair deficient endometrial cancer patients to the MMRd-GREEN trial
* no specific molecular profile endometrial cancer patients to NSMP-ORANGE trial
* POLE mutant endometrial cancer patients to the POLEmut-BLUE trial

Conditions

Interventions

DRUG

Olaparib

300 mg twice daily for one year

RADIATION

Pelvic external beam radiotherapy

45.0-48.6 Gy; 1.8-2.0 Gy per fraction, 5 fractions a week

DRUG

Chemotherapy

Preferably concurrent and adjuvant according to the PORTEC-3 schedule: two cycles of intravenous cisplatin 50mg/m² in the first and fourth week of the pelvic external beam radiotherapy followed by four cycles of intravenous carboplatin AUC 5 and paclitaxel 175 mg/m² at 21-day intervals.

DRUG

Durvalumab

1500 mg intravenous once every 4 weeks for in total 1 year (13 cycles) starting within the first week of radiotherapy,

DRUG

Medroxyprogesterone Acetate

Oral medroxyprogesterone acetate for two years

DRUG

Megestrol Acetate

Oral medroxyprogesterone acetate for two years

RADIATION

Vaginal brachytherapy

Vaginal brachytherapy is to be considered in patients with documented cervical stromal involvement and/or substantial LVSI. Brachytherapy is given with a vaginal cylinder or vaginal ovoids or ring applicator, according to the center's standard technique. When using a cylinder, the active length will ideally be 2-3 cm, with the reference isodose covering the proximal 2.5-3 cm of the vagina. High-dose-rate (HDR) and pulse-dose-rate (PDR) schedules are permitted, which deliver an EQD2 equivalent dose of 10-14 Gy at 5 mm from the vaginal mucosa (to obtain a cumulative EDQ2 of 60 Gy at 5 mm).
