Avelumab and Talazoparib in Untreated Advanced Ovarian Cancer (JAVELIN OVARIAN PARP 100)

Stopped early · Phase 3

Conditions studied: Ovarian Cancer

In brief

JAVELIN Ovarian PARP 100 (B9991030) is an open-label, randomized study designed to evaluate the efficacy and safety of avelumab in combination with chemotherapy followed by maintenance therapy of avelumab in combination with talazoparib versus an active comparator in treatment-naïve patients with locally advanced or metastatic ovarian cancer (Stage III or Stage IV). On March 19, 2019, Sponsors alliance announced the discontinuation of the ongoing Phase III study, and the decision was based on several factors, including previous announced interim results from JAVELIN Ovarian 100 study (B9991010). Patients who remain in B9991030 study will continue receiving their randomized treatment assigned and will be monitored for appropriate safety assessments until treatment discontinuation.

Who can join

Age: 18 and older. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• Histologically confirmed Stage III IV epithelial ovarian, fallopian tube, or primary peritoneal cancer including carcinosarcoma with high-grade serous component.
• Patients must be candidates for bevacizumab in combination with platinum based chemotherapy and previously untreated.
• Must have completed a primary surgical debulking procedure, or be candidates for neoadjuvant chemotherapy with planned interval debulking surgery.
• Patients who completed primary debulking must have had incompletely resected disease that is macroscopically/grossly visible and at least with lesions >1 mm and be randomized at a maximum of 8 weeks after surgery.
• For patients who are candidates for neoadjuvant chemotherapy, the diagnoses must have been confirmed by:
• Core tissue (not fine-needle aspiration) biopsy is required for diagnosis.
• Stage IIIC-IV documented via imaging or surgery (without attempt at cytoreduction).
• Serum CA-125/CEA ratio >25. If the serum CA-125/CEA ratio is <25, then workup should be negative for the presence of a primary gastrointestinal or breast malignancy (<6 weeks before start of neoadjuvant treatment).
• Randomization must occur within 8 weeks after diagnosis.
• Availability of an archival FFPE tumor tissue block or a minimum of 25 slides, together with an accompanying original H\&E slide. If archived FFPE tissue is not available, a de novo (ie, fresh) tumor sample must be obtained in accordance with local institutional practice for tumor biopsies. Tumor tissue must contain 40% or greater tumor nuclei per central laboratory assessment.
• ECOG performance status 0-1
• Age >=18 years (or >=20 years in Japan).
• Adequate bone marrow, hepatic, and renal function and blood coagulation

You may not qualify if…

• Non-epithelial tumors or ovarian tumors with low malignant potential (ie, borderline tumors) or mucinous tumors.
• Patients for whom intraperitoneal cytotoxic chemotherapy is planned.
• Prior exposure to immunotherapy with interleukin (IL)-2, interferon alpha (IFN-α), or an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-cytotoxic T-lymphocyte associated antigen 4 (anti-CTLA4) antibody (including ipilimumab), or any other antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways, excluding therapeutic anticancer vaccines.
• Prior treatment with a PARP inhibitor.
• Prior treatment with any anti-vascular endothelial growth factor (VEGF) drug, including bevacizumab.
• Major surgery (other than debulking or exploratory surgery for ovarian cancer) for any reason within 4 weeks prior to randomization and/or incomplete recovery from surgery.
• Prior radiotherapy to any portion of the abdominal cavity or pelvis. Prior radiation for localized cancer of the breast, head and neck, or skin is permitted, provided that it was completed more than three years prior to registration, and the patient remains free of recurrent or metastatic disease.
• Prior targeted therapy (including but not limited to vaccines, antibodies, tyrosine kinase inhibitors) or hormonal therapy for management of their ovarian, peritoneal primary or fallopian tube carcinoma.
• Prior organ transplantation including allogenic stem cell transplantation.
• Diagnosis of Myelodysplastic Syndrome (MDS).
• Known symptomatic brain metastases requiring steroids. Patients with previously diagnosed brain metastases are eligible if they have completed their treatment and have recovered from the acute effects of radiation therapy or surgery prior to study enrollment, have discontinued corticosteroid treatment for these metastases for at least 4 weeks and are neurologically stable.
