Clovis Focuses on Rubraca Label Expansion, Competition Stiff

Read MoreHide Full Article

We issued an updated research report on Clovis Oncology, Inc. on Apr 17. Shares of the company have increased 15.8% so far this year compared with the industry’s rise of 8.3%.

The commercial portfolio of Clovis consists of a single drug, Rubraca, which is approved as a maintenance treatment in recurrent ovarian cancer patients in second-line setting. The drug is also approved for treating BRCA mutated ovarian cancer in third or later-line setting. The company had in-licensed Rubraca from Pfizer (PFE - Free Report) in 2011.

PARP inhibitor, Rubraca’s sales increased sequentially in seven of the last eight reported quarters. The company’s commercialization efforts including the awareness programs aided sales. Net revenues, entirely from Rubraca, were approximately $95.4 million for full-year 2018, representing year-over-year growth of 71.8%.

Other PARP inhibitors approved for similar indications include Glaxo’s (GSK - Free Report) Zejula and Astrazeneca/Merck’s (MRK - Free Report) Lynparza. Sales of these two drugs have been significantly higher than Rubraca in 2018. With strong balance sheet of these pharma bigwigs, competition is expected to rise as they can spend more on commercialization initiatives.

However, Clovis remains focused on label expansion of Rubraca and launch of the drug in newer countries to boost the prospect of the drug. The company has collaborated with Merck and Bristol-Myers to develop Rubraca in combination with their PD-1/ PDL1 inhibitors, Keytruda and Opdivo, respectively. Apart from ovarian cancer, Rubraca is also being evaluated as monotherapy or in combination for treating several cancer indications including prostate, breast and gastroesophageal cancers, among others.

Clovis is looking to file a regulatory application for label expansion in prostate cancer later this year. Please note that the expansion of Rubraca’s label to include other cancer indications may also face stiff competition. In 2018, two PARP inhibitors were approved for treating breast cancer namely Lynparza and Pfizer’s Talzenna. However, there are no approved PARP inhibitors for prostate cancer yet.

In April 2019, Clovis discontinued phase II ATLAS study evaluating Rubraca monotherapy for metastatic bladder cancer as preliminary data suggested that it was unlikely to provide a meaningful clinical benefit to patients. Such setbacks hurt the prospects of the company.

Apart from Rubraca, the company is developing another candidate, lucitanib, for treating breast and lung cancer.

We will have to wait and see if the sales recovery that started in the fourth quarter continues. Moreover, the rise in mergers and acquisitions so far this year may lead to a buyout offer from any large pharma companies looking to boost their oncology portfolio.
