European Trial on Enhanced DNA Repair Inhibition in Ovarian Cancer

• Status: Active, not recruiting
• Trial end date: 2022-06-30
• Target enrollment: 0
• Participant gender: Female

Summary

This study will be performed in women with platinum-sensitive, high-grade serous, high-grade endometrioid, undifferentiated epithelial ovarian cancer, carcinosarcoma, fallopian tube or primary peritoneal cancer (proven by central histo-pathological review).

A total of 120 subjects will be randomized (1:1:1) to three different treatment arms: (A) Standard arm (arm A): Carboplatin (AUC5 d1, q3w i.v.) in combination with Paclitaxel (175 mg/m² d1, q3w i.v.) or Carboplatin (AUC4 d1, q3w i.v.) in combination with Gemcitabine (1000 mg/m² d1, d8, q3w i.v.) followed by maintenance therapy with Niraparib (200/ 300 mg oral daily, q4w) // (B) First experimental arm (arm B): Ganetespib (150 mg/m2, d1, q3w) in combination with Carboplatin (AUC5 d1, q3w i.v.) followed by maintenance treatment with Niraparib (200/ 300 mg oral daily, q4w) // (C) Second experimental arm (arm C): Ganetespib (150 mg/m² d1, q3w i.v.) plus Carboplatin (AUC5 d1, q3w i.v.) followed by Ganetespib (100 mg/m² d1, d8, d15, d22, q4w i.v.) and Niraparib (200 mg oral daily, q4w).

Chemotherapy treatment will be given for 6 cycles, maintenance treatment with Ganetespib will be given for a maximum of 9 months or until disease progression, maintenance treatment with Niraparib can continue until disease progression.

• SGOT/SGPT (AST/ALT) ≤ 2.5 x upper limit of normal unless liver metastases are present, in which case they must be ≤ 5 x ULN

• Urinanalysis or urine dipstick for proteinuria less than 2+. Patients with ≥ 2+ on dipstick should undergo 24-hour urine collection and must demonstrate < 1 g of protein/24 hours; except the proteinuria is clearly related to a catheter in the urinary system.

• Adequate coagulation parameter: aPTT ≤ 1.5 x ULN (patients on heparin treatment must have an aPTT between 1.5-2.5 x ULN), or INR ≤ 1.5. (In patients receiving anticoagulants (such as warfarin) INR must be between 2.0 and 3.0 in two consecutive measurements 1-4 days apart).

• Participant receiving corticosteroids (dose < 10 mg/day methylprednisolone equivalent), including inhaled steroids, may continue as long as their dose is stable for at least 4 weeks prior to initiating protocol therapy.

• Participants must agree to not donate blood during the study or for 90 days after the last dose of study treatment

• Female participant has a negative serum pregnancy test within 7 days prior to taking study treatment if of childbearing potential and agrees to abstain from activities that could result in pregnancy from screening through 180 days after the last dose of study treatment, or is of non-childbearing potential. Non-childbearing potential is defined as follows (by other than medical reasons):

• ≥ 45 years of age and has not had menses for >1 year

• Patients who have been amenorrhoeic for < 2 years without history of a hysterectomy and oophorectomy must have a follicle stimulating hormone value in the postmenopausal range upon screening evaluation

• Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by imaging. Tubal ligation must be confirmed with medical records of the actual procedure, otherwise the patient must be willing to use 2 adequate barrier methods throughout the study, starting with the screening visit through 180 days after the last dose of study treatment. See below for a list of acceptable birth control methods. Information must be captured appropriately within the site's source documents. Note: Abstinence is acceptable if this is the established and preferred contraception for the patient.

• Birth Control: Participants of childbearing potential who are sexually active and their partners must agree to the use of a highly effective form of contraception throughout their participation beginning with time of consent, during the study treatment and for 180 days after last dose of study treatment(s):

• Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation:

• Oral route

• Intravaginal route

• Transdermal route

• Oral

• Injectable

• Implantable

• Intrauterine device

• Intrauterine hormone-releasing system
