FDA Approves Tablet Formulation of Lynparza (olaparib) for Maintenance Treatment of Ovarian Cancer

August 17, 2017 -- AstraZeneca and Merck & Co., Inc., (Merck: known as MSD outside the U.S. and Canada) today announced that the US Food and Drug Administration (FDA) has granted approval for the PARP inhibitor, Lynparza (olaparib), as follows:

  • New use of Lynparza tablets as a maintenance treatment of adult patients with recurrent, epithelial ovarian, fallopian tube or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy, regardless of BRCA status;1,2
  • New use of Lynparza tablets (2 tablets twice daily) as opposed to capsules (8 capsules twice daily);3
  • Lynparza tablets also now indicated (conversion from the current accelerated approval4) for the use in adult patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCA) advanced ovarian cancer, who have been treated with three or more prior lines of chemotherapy; patients for this indication are selected for therapy based on an FDA-approved companion diagnostic.1

Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer, AstraZeneca said: “Physicians have almost three years of clinical experience with Lynparza on the market and we are now pleased to bring this important medicine, in a new tablet formulation, to a broader group of women. Today’s approvals validate more than 10 years of dedicated research behind Lynparza, the world’s first PARP inhibitor, which now provides oncologists with the greater flexibility for use in terms of treatment settings. It builds on our recently-announced collaboration with Merck, which aims to further increase the number of treatment options available to patients.”

Richard Penson, MD, Clinical Director of Medical Gynecologic Oncology at Massachusetts General Hospital Cancer Center, Associate Professor of Medicine at Harvard Medical School, and the primary investigator in the SOLO-2 trial, said: “Today’s approval demonstrates that olaparib is an effective option for maintenance therapy for certain ovarian cancer patients, regardless of BRCA status. We welcome this news in the ovarian cancer community as more options are important to help us ensure that patients can find a treatment that is right for them.”

Roger M. Perlmutter, President of Merck Research Laboratories, said: “We congratulate AstraZeneca on the approval of these new indications and the new dosage form and schedule for Lynparza, an important therapeutic advance for many patients with ovarian cancer. This is a significant first regulatory event in our collaboration with AstraZeneca. We look forward to working with AstraZeneca in our global collaboration to bring this medicine with its new indications to patients.”

Two randomized trials supported the new approvals and the conversion of accelerated approval to full approval, which was originally based on a single-arm trial:1,3,4

  • SOLO-2 (n=295) confirmed the benefit of Lynparza in gBRCA-mutated patients, demonstrating a 70% reduced risk of disease progression or death (HR 0.30 [95% CI, 0.22-0.41], P<0.0001) and improved median progression-free survival (PFS) to 19.1 vs 5.5 months for placebo by investigator-assessed analysis.1
  • Study 19 (n=265) showed that Lynparza reduced the risk of disease progression or death by 65% and improved PFS compared with placebo in patients of any BRCA status (HR 0.35 [95% CI, 0.25-0.49], P<0.0001; median PFS of 8.4 months with Lynparza vs 4.8 months with placebo).1 Additionally, patients in Study 19, treated with Lynparza as a maintenance therapy, had a median overall survival (OS) of 29.8 months vs 27.8 months for placebo (HR 0.73 [95% CI, 0.55-0.95]).1

The most common adverse reactions (≥20%) in clinical trials were anemia, nausea, fatigue (including asthenia), vomiting, nasopharyngitis/upper respiratory tract infection/influenza, diarrhea, arthralgia/myalgia, dysgeusia, headache, dyspepsia, and decreased appetite, constipation. and stomatitis. Most common laboratory abnormalities (≥25%) were decrease in hemoglobin, increase in mean corpuscular volume, decrease in lymphocytes, decrease in leukocytes, decrease in absolute neutrophil count, increase in serum creatinine and decrease in platelets.1

The full data from the SOLO-2 trial can be found in the July 25, 2017 publication of The Lancet Oncology.5

Lynparza was first approved under the FDA’s Accelerated Approval program in December 2014, as a capsule formulation, making it the first poly ADP-ribose polymerase (PARP) inhibitor approved.3,6 Since then, more than 3,000 advanced ovarian cancer patients have been treated with Lynparza capsules.7 Lynparza capsules are not indicated for maintenance therapy.1

IMPORTANT SAFETY INFORMATION

DOSING AND ADMINISTRATION

To avoid substitution errors and overdose, do not substitute Lynparza tablets with Lynparza capsules on a milligram-to-milligram basis due to differences in the dosing and bioavailability of each formulation. Recommended tablet dose is 300 mg, taken orally twice daily, with or without food. Continue treatment until disease progression or unacceptable toxicity. For adverse reactions, consider dose interruption or dose reduction.

About SOLO-2

SOLO-2 was a Phase III, randomized, double-blind, multicenter trial designed to determine the efficacy of Lynparza tablets as a maintenance monotherapy compared with placebo, in patients with platinum-sensitive, relapsed or recurrent gBRCA-mutated ovarian, fallopian tube and primary peritoneal cancer.8 The trial, conducted in collaboration with the European Network for Gynaecological Oncological Trial Groups (ENGOT) and Groupe d’Investigateurs National pour l’Etude des Cancers de l’Ovaire et du sein (GINECO), randomized 295 patients with documented germline BRCA1 or BRCA2 mutations who had received at least two prior lines of platinum-based chemotherapy and were in complete or partial response.5,8 Eligible patients were randomized to receive either Lynparza tablets (300mg twice daily) or placebo twice daily.5

About Study 19

Study 19 was a Phase II, randomized, double-blind, placebo-controlled, multicenter trial, which evaluated the efficacy and safety of Lynparza capsules compared with placebo in relapsed, high-grade serous ovarian cancer patients, involving 82 sites across 16 countries. Patients received olaparib maintenance monotherapy, at a dose of 400mg per day or matching placebo. Treatment continued until disease progression provided that toxicities were manageable.2

About Lynparza (olaparib)

Lynparza was the first FDA-approved oral poly ADP-ribose polymerase (PARP) inhibitor that may exploit tumor DNA damage response (DDR) pathway deficiencies to potentially kill cancer cells.6,9,10 Specifically, in vitro studies have shown that olaparib-induced cytotoxicity may involve inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes, resulting in DNA damage and cancer cell death.1

Lynparza is the foundation of AstraZeneca’s industry-leading portfolio of compounds targeting DDR mechanisms in cancer cells.6,9,10

Lynparza tablets are currently being investigated in combinations in a range of tumor types, including breast, prostate, and pancreatic cancer.11-14

Lynparza capsules (400mg twice daily) will still be available through a limited specialty pharmacy network, for patients currently being treated for deleterious or suspected deleterious germline BRCA-mutated advanced ovarian cancer who have been treated with three or more prior lines of chemotherapy. Lynparza tablets and capsules are not the same.1

If you have been prescribed Lynparza tablets, do not take the capsules. If you have any questions about Lynparza, please talk with your physician or pharmacist.1

About the AstraZeneca and Merck Strategic Oncology Collaboration

On July 27, 2017, AstraZeneca and Merck & Co., Inc., announced a global strategic oncology collaboration to co-develop and co-commercialize AstraZeneca’s Lynparza, the world’s first and leading PARP inhibitor, and potential new medicine selumetinib, a MEK inhibitor, for multiple cancer types. The collaboration is based on increasing evidence that PARP and MEK inhibitors can be combined with PDL-1/PD-1 inhibitors for a range of tumor types and is aimed at maximizing the potential of Lynparza to become the preferred backbone of combination therapies. Working together, the companies will jointly develop Lynparza and selumetinib in combination with other potential new medicines and as a monotherapy. Independently, the companies will develop Lynparza and selumetinib in combination with their respective PD-L1 and PD-1 medicines.
