Olaparib Maintenance in Patients With MCRPC After Docetaxel Treatment Reaching Partial or Stable Response (IMANOL) (IMANOL)
Phase II Trial Evaluating Olaparib Maintenance in Patients With MCRPC After Docetaxel Treatment Reaching Partial or Stable Response.
A number of important systemic therapies have been developed to treat mCRPC and have received regulatory approval and now comprise the current therapeutic landscape. Durable and complete response following first-line chemotherapy in patients with advanced PC are uncommon. Most patients will ultimately experience disease progression within 6-9 months after initial response. Optimal Second line therapy in mCRPC is not well established and several options are possible.
Olaparib has demonstrated anti-tumour activity in non-comparative studies in patients with germline BReast CAncer gene (gBRCA) mutated cancers including ovarian, breast, pancreas and prostate. Olaparib is indicated as monotherapy for the maintenance treatment of adult patients with platinum-sensitive relapsed Breast Cancer gene-mutated (germline and/or somatic) high grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in response (complete response or partial response) to platinum-based chemotherapy.
This phase II study is developed to assess the effect of maintenance treatment with olaparib on radiologic progression free survival (rPFS) in patients with mCRPC who have received at least 6 cycles of docetaxel and achieved partial or complete response or disease stabilization according RECIST 1.1 criteria and PCWG3.

Description
Inclusion Criteria:
- Provision of informed consent prior to any study specific procedures. For inclusion in the study patients must provide the informed consent also for genetic research. Genetic counselling for patients with germline mutation in any of the Homologous Recombination Repair genes should be performed.
- Male patients, who must be ≥18 years of age.
- Histologically confirmed prostate adenocarcinoma.
- Patients must have metastatic disease before starting treatment with docetaxel (metastatic disease documented by positive bone scan or metastatic lesions on CT, MRI).
- No prior exposure to platinum, cyclophosphamide, mitoxantrone or Polyadenosine 5'diphosphoribose polymerisation (PARP) inhibitors.
- No cancer progression on the basis of Prostate Cancer Working Group (PCWG3) criteria to docetaxel therapy.
- Completed at least six cycles and a maximum of ten cycles of chemotherapy containing docetaxel.
- Patients are allowed to have received treatment for mCRPC before docetaxel (abiraterone, enzalutamide, radium 223,etc.; patients that have received prior docetaxel in hormone-sensitive setting are also allowed).
- Documented germline/somatic mutation in any of the Homologous Recombination Repair genes, including among others, BRCA1 or BRCA2, ATM, Fanconi genes, CHEK2, mutL homolog 1 (MLH1), mutS homologue 2 (MSH2), mutS homolog 6 (MSH6), PMS2, PALB2, RAD51C, MRE11 that is predicted to be deleterious or suspected deleterious (known or predicted to be detrimental/lead to loss of function).
Patients must have normal organ and bone marrow function measured within 28 days prior to administration of study treatment as defined below:
- Haemoglobin ≥ 10.0 g/dL with no blood transfusion in the past 28 days.
- Absolute neutrophil count (ANC) ≥ 1.5 x 109/L.
- Platelet count ≥ 100 x 109/L.
- Total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN).
- Aspartate aminotransferase (AST) (Serum Glutamic Oxaloacetic Transaminase ((SGOT)) / Alanine aminotransferase (ALT) (Serum Glutamic Pyruvate Transaminase (SGPT)) ≤ 2.5 x institutional upper limit of normal unless liver metastases are present in which case they must be ≤ 5x ULN.
- Patients must have creatinine clearance estimated using the Cockcroft-Gault equation of ≥51 mL/min:
Estimated creatinine clearance = ((140-age [years]) x weight (kg) (x F)^a) / serum creatinine (mg/dL) x 72 F=1 for males.
- Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
- Patients must be able to take oral medication.
- Patients must have a life expectancy ≥ 16 weeks.
- Male patients and their partners, who are sexually active and of childbearing potential, must agree to the use of two highly effective forms of contraception in combination [see appendix A for acceptable methods], throughout the period of taking study treatment and for 3 months after last dose of study drug(s) to prevent pregnancy in a partner.
- Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations.
- Formalin fixed, paraffin embedded (FFPE) tumour sample from the primary cancer must be available for central testing. If there is not written confirmation of the availability of an archived tumour sample prior to enrolment the patient is not eligible for the study.
Exclusion Criteria:
- Involvement in the planning and/or conduct of the study (applies to AstraZeneca or sponsor staff and/or staff at the study site).
- Previous inclusion in the present study.
- Participation in another clinical study with an investigational product during the last month.
- Any previous treatment with PARP inhibitor, including olaparib.
- Patients who do not have deleterious or suspected deleterious Homologous Recombination Repair genes mutations and only have Homologous Recombination Repair genes mutations that are considered to be non-detrimental (e.g., "Variants of uncertain clinical significance" or "Variant of unknown significance" or "Variant, favour polymorphism" or "benign polymorphism" etc.).
