Issued: 3 December 2018, London UK – LSE Announcement
GSK reaches agreement to acquire TESARO, an oncology focused biopharmaceutical company
GlaxoSmithKline plc (LSE/NYSE: GSK) and TESARO Inc (NASDAQ: TSRO) today announced that the Companies have entered into a definitive agreement pursuant to which GSK will acquire TESARO, an oncology-focused company based in Waltham, Massachusetts, for an aggregate cash consideration of approximately $5.1 billion (£4.0 billion). The proposed transaction will significantly strengthen GSK’s pharmaceutical business, accelerating the build of GSK’s pipeline and commercial capability in oncology.
TESARO is a commercial-stage biopharmaceutical company, with a major marketed product, Zejula (niraparib), an oral poly ADP ribose polymerase (PARP) inhibitor currently approved for use in ovarian cancer. PARP inhibitors are transforming the treatment of ovarian cancer, notably demonstrating marked clinical benefit in patients with and without germline mutations in aBRCA gene (gBRCA). Zejula is currently approved in the US and Europe as a treatment for adult patients with recurrent ovarian cancer who are in response to platinum-based chemotherapy, regardless ofBRCA mutation or biomarker status.
Clinical trials to assess the use of Zejula in“all-comers” patient populations, as a monotherapy and in combinations, for the significantly larger opportunity of first line maintenance treatment of ovarian cancer are also underway. These ongoing trials are evaluating the potential benefit of Zejula in patients who carry gBRCAmutations as well as the larger population of patients withoutgBRCA mutations whose tumours areHRD-positive andHRD-negative. Results from the first of these studies, PRIMA, are expected to be available in the second half of 2019.
GSK also believes PARP inhibitors offer significant opportunities for use in the treatment of multiple cancer types. In addition to ovarian cancer, Zejula is currently being investigated for use as a possible treatment in lung, breast and prostate cancer, both as a monotherapy and in combination with other medicines, including with TESARO’s ownanti-PD-1 antibody (dostarlimab, formerly known asTSR-042).
In addition to Zejula, TESARO has several oncology assets in its pipeline including antibodies directed againstPD-1,TIM-3 andLAG-3 targets.
Emma Walmsley, Chief Executive Officer, GSK, said:“The acquisition of TESARO will strengthen our pharmaceuticals business by accelerating the build of our oncology pipeline and commercial footprint, along with providing access to new scientific capabilities. This combination will support our aim to deliver long-term sustainable growth and is consistent with our capital allocation priorities. We look forward to working with TESARO’s talented team to bring valuable new medicines to patients.”
Hal Barron, Chief Scientific Officer and President, R&D, GSK, said: “Our strong belief is that PARP inhibitors are important medicines that have been under appreciated in terms of the impact they can have on cancer patients. We are optimistic that Zejula will demonstrate benefit in patients with ovarian cancer beyond those who are BRCA-positive as front-line treatment. We are also very excited that through this transaction, we will have the opportunity to work with an outstanding Boston-based oncology group with deep clinical development expertise and together we will explore Zejula’s efficacy beyond ovarian cancer into multiple tumour types to help many more patients.”
Lonnie Moulder, Chief Executive Officer, TESARO, said:“This transaction marks the beginning of a new global partnership that will accelerate our oncology business and allow our mission of delivering transformative products to individuals living with cancer to endure. Our Board and
PRESS RELEASE | |
Management team are very pleased to announce this transaction, and we are grateful to the management team at GSK for their tremendous vision and the opportunity to preserve and build upon the impact we have had in the cancer community to date.”
Mary Lynne Hedley, President and Chief Operating Officer, TESARO, said:“This partnership marks an evolution in the way we live out the TESARO mission and will allow us to more rapidly deliver on our commitment to patients. I am excited to be partnering with our new colleagues at GSK as together we advance innovative scientific and drug development strategies that ultimately enable us to provide more time for more patients.”
Financial highlights
The acquisition price of $75 per share in cash represents a 110% premium to TESARO’s 30 day Volume Weighted Average Price of $35.67 and an aggregate consideration of approximately $5.1 billion (£4.0 billion) including the assumption of TESARO’s net debt.
Zejula’s revenues in its current approved indication as second-line maintenance treatment for ovarian cancer were $166 million for the 9 months ended 30 September 2018.
GSK expects the acquisition of TESARO and associated R&D and commercial investments will impact Adjusted EPS for the first two years by mid to high single digit percentages, reducing thereafter with the acquisition expected to start to be accretive to Adjusted EPS by 2022.
GSK’s guidance for full-year 2018 Adjusted EPS growth remains unchanged at 8 to 10% at CER. GSK continues to expect to deliver on its previously published Group Outlooks to 2020, but following the acquisition of TESARO now expects Adjusted EPS growth at CER for the period 2016-2020 to be at the bottom end of the mid to high single digit percentage CAGR range.
Guidance and Group Outlooks are given on the bases set out on pages 37 and 38 of GSK’s Q3 2018 results, including definitions of CER growth and Adjusted results.
GSK confirms no change to its current dividend policy and continues to expect to pay 80p in dividends for 2018.
GSK expects to fund the acquisition from cash resources and drawing under a new acquisition facility.
Structure and Terms of the Transaction
Under the terms of the merger agreement between GSK and TESARO, unanimously approved by TESARO’s Board of Directors, an indirect subsidiary of GSK will commence a tender offer within the next 10 business days to acquire all of the issued and outstanding shares of TESARO common stock for a price of $75 per share in cash upon completion of the offer. The transaction is expected to complete in the first quarter of 2019, subject to satisfaction of customary closing conditions, including the tender by TESARO stockholders of at least one share more than 50% of the issued and outstanding shares of TESARO and required regulatory approvals, including clearance by the US Federal Trade Commission. Following closing of the tender offer, GSK will acquire any shares of TESARO that are not tendered in the tender offer through a second-step merger under Delaware law at the tender offer price.
The value of the gross assets of TESARO to be acquired (as at 30 September 2018) is $711 million (£555 million at the rate of £1 = $1.28, being the 30 November spot rate). The net losses of the business were $466 million for the 9 months ended 30 September 2018 (£345 million, at the rate of £1 = $1.35, being the average rate for the 9 months ended 30 September 2018).
GSK is in discussions with several key executives of TESARO to ensure their continued employment with the company.

TESARO portfolio and pipeline
Zejula is an orally active and potent polyADP-ribose polymerase (PARP) inhibitor. PARP is a family of proteins involved in many functions in a cell, including DNA repair, gene expression, cell cycle control, intracellular trafficking and energy metabolism. PARP proteins play key roles in single strand break repair through the base excision repair pathway. PARP inhibitors have shown activity as a monotherapy against tumours with existing DNA repair defects, such asBRCA1 andBRCA2, and as a combination therapy when administered together with anti- cancer agents that induce DNA damage or activate the immune system.
TESARO’s development pipeline also has a number of novel oncology candidates that modulate the function of the immune system via different mechanisms. By blocking the interaction ofPD-1,TIM-3 andLAG-3 with their respective ligands, antibodies to these targets aim to restore immune anti-cancer function in patients across a variety of tumour types.

About Zejula (niraparib)
Zejula (niraparib) is a poly(ADP-ribose) polymerase (PARP) inhibitor indicated for the 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. In preclinical studies, Zejula concentrates in the tumour relative to plasma, delivering greater than 90% durable inhibition of PARP 1/2 and a persistent antitumour effect. Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML), including some fatal cases, was reported in patients treated with Zejula. Discontinue Zejula if MDS/AML is confirmed. Hematologic adverse reactions (thrombocytopenia, anemia and neutropenia), as well as cardiovascular effects (hypertension and hypertensive crisis) have been reported in patients treated with Zejula. Monitor complete blood counts to detect hematologic adverse reactions, as well as to detect cardiovascular disorders, during treatment. Zejula can cause fetal harm and females of reproductive potential should use effective contraception. Please see full prescribing information, including additional important safety information, available at www.zejula.com.
About Ovarian Cancer
Approximately 22,000 women are diagnosed with ovarian cancer each year in the US, and more than 65,000 women are diagnosed annually in Europe. Ovarian cancer is the fifth leading cause of cancer death among women. Despite high-response rates to platinum-based chemotherapy in the second-line advanced treatment setting, approximately 85% of patients with advanced ovarian cancer will experience recurrence. Once ovarian cancer recurs, it’s considered incurable. From there, with each recurrence, the time a woman may spend without her cancer progressing until the next recurrence gets shorter.
About PARPInhibitor/PARP-1 andPARP-2 Inhibitors
PARP, orpoly(ADP-ribose) polymerase, is a family of proteins that helps repair damaged DNA in cells. A PARP inhibitor like Zejula may prevent cancer cells from repairing their damaged DNA, which can cause cancer cells to die. This may slow the return or progress of cancer. Zejula can also impact other cells and tissues in the body
About BRCA / HRD
BRCA is a gene that is linked to increased risk for cancer. Mutations in this gene can prevent DNA repair. Mutations or aberrations in BRCA or other genes that prevent DNA repair result in a state of homologous recombination deficiency, or “HRD”. Cancer cells with HRD are especially sensitive to PARP inhibitors, which have been shown to shrink tumours in patients with HRD and increase the time in which patients are free from cancer progression. The genomic tests used to define HRD are evolving. To date, clinical studies of PARP inhibitors have primarily relied on tests for BRCA gene mutations to select patients for treatment with a PARP inhibitor. Other tests, such as MyChoice and FoundationOne have been used in clinical trials of ovarian cancer to identify patients whose tumors have HRD and are sensitive to PARP inhibitors. However, more sensitive tests involving such things as whole genome screening and functional genomic analyses are needed to identify additional patients with cancer who might benefit from treatment with PARP inhibitors.
