Abstract:
Rucaparib (Rubraca®) is a small molecule poly(ADP-ribose) polymerase (PARP) inhibitor with potent activity against PARP-1, -2 and -3. It is approved in the USA and the EU for the treatment of adult patients with BRCA-mutated ovarian cancer who have been treated with two or more lines of chemotherapy. Rucaparib is also approved in the USA and the EU for use as maintenance therapy in adult patients with recurrent or relapsed ovarian cancer who are in a complete or partial response to platinum-based chemotherapy. Based on an analysis of patients across two phase II clinical trials, rucaparib displayed clinical activity as third- (or later-) line treatment of BRCA-mutated ovarian cancer, with rucaparib-treated patients having a confirmed objective response rate of 54%. Furthermore, as demonstrated in the randomized, placebo-controlled, phase III ARIEL3 trial, rucaparib significantly improved progression-free survival when used as maintenance treatment in patients with platinum-sensitive ovarian cancer. Rucaparib had an acceptable tolerability profile in clinical trials in women with ovarian cancer. Common adverse events were generally manageable with dose modification and/or supportive care. Thus, currently available data indicate that rucaparib is a useful addition to the options available to clinicians for the treatment of advanced ovarian cancer, in both the treatment and maintenance therapy settings.
Insights
Rucaparib, a PARP inhibitor, shows significant efficacy in treating advanced ovarian cancer. It is effective as both a treatment and maintenance therapy for patients with BRCA mutations and platinum-sensitive disease.
Area of Science:
- Oncology
- Pharmacology
Background:
- Rucaparib is a poly(ADP-ribose) polymerase (PARP) inhibitor approved for BRCA-mutated ovarian cancer.
- It is used for treatment after chemotherapy and as maintenance therapy for recurrent or relapsed ovarian cancer.
Purpose of the Study:
- To evaluate the clinical activity and tolerability of rucaparib in advanced ovarian cancer.
- To assess rucaparib's efficacy as third-line treatment and maintenance therapy.
Main Methods:
- Analysis of patients from two Phase II clinical trials for third-line treatment.
- Evaluation of the randomized, placebo-controlled, Phase III ARIEL3 trial for maintenance therapy.
Main Results:
- Rucaparib demonstrated a 54% objective response rate in third-line treatment of BRCA-mutated ovarian cancer.
- The ARIEL3 trial showed significantly improved progression-free survival with rucaparib maintenance therapy in platinum-sensitive ovarian cancer.
- Rucaparib exhibited an acceptable and manageable tolerability profile.
Conclusions:
- Rucaparib is a valuable treatment option for advanced ovarian cancer.
- It offers clinical benefits in both treatment and maintenance settings for specific patient populations.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
