PARP and prostate cancer

PROFOUND study

Reference NEJM: Olaparib mCRPC

Germline and somatic BRCA mutation, progressed on hormonal agent like abi or enza

Longer PFS by 3 months in PARP group( 7.4 versus 3.6 months)

Anemia is the most common AE. No AML or MDS reported.

Nausea also common


Key points

  1. ATM mutations do not respond to PARP inhibitors
  2. Can use PARP inhibitor even with monoallelic BRCA mutation
  3. DO not sequence another PARP after failure of one PARP
  4. Do germline testing in all metastatic prostate cancer patients. Somatic testing is also recommended.
