Olaparib, marketed under the trade name Olanib among others, is a medication primarily used in the treatment of specific types of cancers. It is a potent oral poly (ADP-ribose) polymerase (PARP) inhibitor. PARP is an enzyme that plays a critical role in DNA repair, and by inhibiting this enzyme, Olaparib exploits the defective DNA repair pathways in cancer cells, leading to cell death. This makes Olaparib particularly effective in treating cancers with specific genetic mutations, such as BRCA1 and BRCA2 mutations.
Mechanism of Action
Olaparib works by blocking the PARP enzyme, which is Olanib (Olaparib) 150 mg involved in repairing damaged DNA. Cancer cells, particularly those with BRCA mutations, rely heavily on PARP due to their already compromised DNA repair mechanisms. When PARP is inhibited, these cancer cells accumulate DNA damage and eventually die. This targeted mechanism spares most normal cells, reducing the side effects compared to traditional chemotherapy.
Indications and Usage
Olaparib is primarily used for the treatment of:
Ovarian Cancer: For patients with BRCA-mutated ovarian cancer, either as a maintenance therapy after chemotherapy or for treating advanced cases.
Breast Cancer: Specifically, for patients with HER2-negative metastatic breast cancer with a germline BRCA mutation.
Pancreatic Cancer: For maintenance treatment of patients with germline BRCA-mutated metastatic pancreatic cancer.
Prostate Cancer: For treating patients with metastatic castration-resistant prostate cancer with certain homologous recombination repair (HRR) gene mutations, including BRCA.
Administration and Dosage
Olaparib is administered orally, typically in the form of 150 mg tablets. The usual recommended dose is 300 mg (two 150 mg tablets) taken twice daily. It is important that patients adhere to this regimen and take the medication with or without food. Dose adjustments might be necessary based on individual tolerance and side effects.
Efficacy
Clinical trials have demonstrated the efficacy of Olaparib in prolonging progression-free survival (PFS) in patients with BRCA-mutated cancers. For instance, in ovarian cancer, studies have shown a significant extension in PFS compared to placebo. Similar benefits have been observed in breast, pancreatic, and prostate cancers, highlighting Olaparib’s role as a vital component in the management of these cancers.
