• Rucaparib now available in multiple countries across Europe

BOULDER, Colo.--(BUSINESS WIRE)-- Clovis Oncology, Inc. (NASDAQ: CLVS) today announced that Rubraca^® (rucaparib) is now available and reimbursed in France. Rubraca^® (rucaparib) is an option for monotherapy maintenance treatment for adults with relapsed, platinum-sensitive high-grade epithelial ovarian, fallopian tube or primary peritoneal cancer that has responded to platinum-based chemotherapy.² Rucaparib is indicated for eligible patients regardless of BRCA status, which means it can be prescribed for women who harbor a BRCA mutation or who are BRCA wild-type.²

“This is excellent news as this represents an important new option for patients with relapsed ovarian cancer who have responded to platinum-based chemotherapy,” said a spokesperson for IMAGYN, the only French network of patient associations involved in the fight against ovarian cancer and gynecological tumors. “For too long, ovarian cancer treatment options beyond chemotherapy, surgery and anti-angiogenic therapy have been limited, and today’s announcement means that eligible women with ovarian cancer have more choice in their treatment than ever before.”

Approximately 5,000 women are diagnosed with ovarian cancer in France every year, which equates to roughly 14 every day.³ Ovarian cancer is the eighth most common cancer in women and the fourth most fatal cancer in France.⁴ In addition, approximately 25 percent of ovarian cancer patients harbor a BRCA1/2 mutation in the tumor, correlating to improved outcomes to platinum and PARP inhibitors therapy.^5,6 The majority of women diagnosed with ovarian cancer are BRCA wild-type; these patients typically have a worse prognosis.^5,6 Of those treated with surgery and first line chemotherapy, approximately 70 percent of patients will relapse within the first three years.⁷

“The availability of rucaparib is good news, as ovarian cancer is a disease often diagnosed at an advanced stage and many women may have a poor prognosis,” said Professor Isabelle Ray-Coquard, President of the GINECO Group, which specializes in clinical and translational research in the field of women’s cancers, and sets up and coordinates clinical trials in France and abroad. “Patients with relapsed ovarian cancer may have many debilitating symptoms, and it is important that new treatments such as rucaparib are made available to the eligible patients that may benefit from them.”

The European Union (EU) authorization is based on data from the pivotal phase 3 ARIEL3 clinical trial, which found that rucaparib significantly improved PFS in all ovarian cancer patient populations studied.¹ ARIEL3 successfully achieved its primary endpoint of extending investigator-assessed PFS versus placebo in all patients treated (intention-to-treat, or ITT), population, regardless of BRCA status (median 10.8 months vs 5.4 months).^1,2 In this population, the risk of progression or death has been decreased by 64%.¹ In addition, it successfully achieved the key secondary endpoint of extending PFS by independent radiological review versus placebo in all patients treated (ITT), regardless of BRCA status (median 13.7 months vs 5.4 months).² The overall safety profile of rucaparib is based on data from 937 patients with ovarian cancer treated with rucaparib monotherapy in clinical trials.²

“The fact that rucaparib is now reimbursed and available in France means there is a new treatment for patients with platinum-sensitive relapsed ovarian cancer,” said Dr. Anne Floquet, President of the SFOG, the French Society for Gyneco-Oncology. “I am very proud to have been able to participate in the ARIEL3 study, which demonstrates the effectiveness of rucaparib in improving patients’ progression-free survival. I am also delighted to be able to prescribe this treatment as it may offer benefits for eligible patients.”

“We are working to make Rubraca available in multiple countries across Europe, and with the reimbursement and availability of Rubraca in France, it is now a treatment option for eligible patients in Germany, England, Italy, and in France,” said Patrick J. Mahaffy, President and CEO of Clovis Oncology. “Rubraca is effective across a broad population of women with relapsed ovarian cancer and is an important step in the ovarian cancer treatment pathway for eligible patients.”

About Rubraca^® (rucaparib)

Rubraca is an oral, small molecule inhibitor of PARP1, PARP2 and PARP3 that is being developed in multiple tumor types, including ovarian and metastatic castration-resistant prostate cancer (mCRPC), as monotherapy, and in combination with other anti-cancer agents. Exploratory studies in other tumor types are also underway.

Rubraca^® (rucaparib) European Union (EU) authorized use and Important Safety Information

Rubraca is indicated as monotherapy for the maintenance treatment of adult patients with platinum-sensitive relapsed high-grade epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in response (complete or partial) to platinum-based chemotherapy.

Rubraca is indicated as monotherapy treatment of adult patients with platinum sensitive, relapsed or progressive, BRCA mutated (germline and/or somatic), high-grade epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have been treated with ≥2 prior lines of platinum-based chemotherapy, and who are unable to tolerate further platinum-based chemotherapy.

Efficacy of Rubraca as treatment for relapsed or progressive EOC, FTC, or PPC has not been investigated in patients who have received prior treatment with a PARP inhibitor. Therefore, use in this patient population is not recommended.

Summary warnings and precautions:

Hematological toxicity

During treatment with Rubraca, events of myelosuppression (anemia, neutropenia, thrombocytopenia) may be observed and are typically first observed after 8–10 weeks of treatment with Rubraca. These reactions are manageable with routine medical treatment and/or dose adjustment for more severe cases. Complete blood count testing prior to starting treatment with Rubraca, and monthly thereafter, is advised. Patients should not start Rubraca treatment until they have recovered from hematological toxicities caused by previous chemotherapy (CTCAE grade ≥1).

Supportive care and institutional guidelines should be implemented for the management of low blood counts for the treatment of anemia and neutropenia. Rubraca should be interrupted or dose reduced according to Table 1 (see Posology and Method of Administration [4.2] of the Summary of Product Characteristics [SPC]) and blood counts monitored weekly until recovery. If the levels have not recovered to CTCAE grade 1 or better after 4 weeks, the patient should be referred to a hematologist for further investigations.

MDS/AML

MDS/AML, including cases with fatal outcome, have been reported in patients who received Rubraca. The duration of therapy with Rubraca in patients who developed MDS/AML varied from less than 1 month to approximately 28 months.

If MDS/AML is suspected, the patient should be referred to a hematologist for further investigations, including bone marrow analysis and blood sampling for cytogenetics. If, following investigation for prolonged hematological toxicity, MDS/AML is confirmed, Rubraca should be discontinued.

Photosensitivity

Photosensitivity has been observed in patients treated with Rubraca. Patients should avoid spending time in direct sunlight because they may burn more easily during Rubraca treatment; when outdoors, patients should wear a hat and protective clothing, and use sunscreen and lip balm with sun protection factor of 50 or greater.

Gastrointestinal toxicities

Gastrointestinal toxicities (nausea and vomiting) are frequently reported with Rubraca, and are generally low grade (CTCAE grade 1 or 2), and may be managed with dose reduction (refer to Posology and Method of Administration [4.2], Table 1 of the SPC) or interruption. Antiemetics, such as 5-HT3 antagonists, dexamethasone, aprepitant and fosaprepitant, can be used as treatment for nausea/vomiting and may also be considered for prophylactic (i.e. preventative) use prior to starting Rubraca. It is important to proactively manage these events to avoid prolonged or more severe events of nausea/vomiting which have the potential to lead to complications such as dehydration or hospitalization.

Embryofetal toxicity

Rubraca can cause fetal harm when administered to a pregnant woman based on its mechanism of action and findings from animal studies. In an animal reproduction study, administration of Rubraca to pregnant rats during the period of organogenesis resulted in embryo-fetal toxicity at exposures below those in patients receiving the recommended human dose of 600 mg twice daily (see Preclinical Safety Data [5.3] of the SPC).

Pregnancy/contraception

Pregnant women should be informed of the potential risk to a fetus. Women of reproductive potential should be advised to use effective contraception during treatment and for 6 months following the last dose of Rubraca (see section 4.6 of the SPC). A pregnancy test before initiating treatment is recommended in women of reproductive potential.
