Rucaparib (AG 014699) is a PARP inhibitor being investigated as a potential anti-cancer agent.

Rucaparib inhibits “the contraction of isolated vascular smooth muscle, including that from the tumours of cancer patients. It also reduces the migration of some cancer and normal cells in culture.”[1]

It can be taken orally in tablet form.[2]

It has undergone phase I clinical trials for patients with advanced solid tumours.[3] It is in phase II clinical trials for metastatic breastand ovarian cancer with known BRCA1 or BRCA2 mutation.[4][2]

It is thought that 20% of women with ovarian cancer who are not BRCA positive might also benefit from PARP inhibitors. Clinical trials are beginning (as of April, 2014)

As of November 2012 four clinical trials of rucaparib were recruiting patients.[5]
Inhibition of poly(ADP ribose) polymerase, or PARP, is an exciting new mechanism for the treatment of cancer.(1) The PARP enzyme is responsible for repair of damaged DNA in both normal and tumor cells, and inhibition of this repair mechanism is expected to make the cell more likely to undergo apoptosis. Preclinical work has shown that PARP inhibitors coadministered with a standard chemotherapuetic agent are more effective than the standard treatment aloneRucaparib is a NAD+ ADP-ribosyltransferase inhibitor in phase II clinical development at Cancer Research UK for the treatment of patients with advanced ovarian cancer and in patients with locally advanced or metastatic breast cancer. Clovis Oncology is conducting early clinical evaluation of rucaparib for the treatment of triple negative breast cancer or ER/PR +, HER2 negative with known BRCA1/2 mutations p2 and for the treatment of gBRCA mutation breast cancer.. Pfizer discontinued development of rucaparibin 2011.In 2011, the compound was licensed to Clovis Oncology by Pfizer for the treatment of cancer. In 2012, orphan drug designation was assigned in the U.S. and the E.U. for the treatment of ovarian cancer.

PAPER

Org. Process Res. Dev., 2012, 16 (12), pp 1897–1904
DOI: 10.1021/op200238p

http://pubs.acs.org/doi/full/10.1021/op200238pAbstract ImageNovel PARP inhibitor 1 is a promising new candidate for treatment of breast and ovarian cancer. A modified synthetic route to 1 has been developed and demonstrated on 7 kg scale. In order to scale up the synthesis to multikilogram scale, several synthetic challenges needed to be overcome. The key issues included significant thermal hazards present in a Leimgruber–Batcho indole synthesis, a low-yielding side-chain installation, a nonrobust Suzuki coupling and hydrogen cyanide generation during a reductive amination. In addition to these issues, changing from intravenous to oral delivery required a new salt form and therefore a new crystallization procedure. This contribution describes development work to solve these issues and scaling up of the new process in the pilot plant.

Clovis Oncology receives Breakthrough Therapy designation for rucaparib for treatment of advanced ovarian cancer in patients with BRCA-mutated tumours

7 April 2015  •  Author: Victoria White

Clovis Oncology has announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation for the Company’s investigational agent rucaparib as monotherapy treatment of advanced ovarian cancer in patients who have received at least two lines of prior platinum-containing therapy, with BRCA-mutated tumours, inclusive of both germline BRCA (gBRCA) and somatic BRCA (sBRCA) mutations.

are a biopharmaceutical company focused on acquiring, developing and commercializing cancer treatments in the United States, Europe and other international markets. Our development programs are targeted at specific subsets of cancer, combining personalized medicine with companion diagnostics to direct therapeutics to those patients most likely to benefit from them.

We have three product candidates in clinical development: rociletinib (CO-1686), which is in Phase II development for the treatment of non-small cell lung cancer; rucaparib, which is in Phase II and Phase III clinical trials for the treatment of ovarian cancer; and lucitanib, which is in Phase II clinical trials for the treatment of breast and lung cancers. We have received Breakthrough Therapy designation from the FDA for rociletinib and rucaparib. We maintain global rights for rociletinib and rucaparib, and U.S. and Japanese rights to lucitanib.
