"The three-year overall survival follow-up data from COMBI-v is remarkable because it is the second Phase III study this year to demonstrate a significant long-term survival benefit for BRAF mutation-positive melanoma patients treated with Tafinlar + Mekinist combination therapy compared to BRAF inhibitor monotherapy," said Caroline Robert, MD, PhD, Head of Dermatology, Institute Gustave-Roussy. "The results of this trial continue to reinforce Tafinlar + Mekinist as a standard of care and sets a new benchmark for treating patients with BRAF V600 mutation-positive advanced melanoma."

Results from the COMBI-v study found the estimated three-year survival rate to be 45% of patients receiving the combination of Tafinlar + Mekinist (95% CI, 39.1%-49.8%) compared with 31% of patients who received vemurafenib monotherapy (95% CI, 26.1%-36.4%)[1]. There were 34 patients who crossed over from the vemurafenib monotherapy arm to the combination arm after the combination demonstrated a significant OS benefit in a prior analysis[1]. Additionally, the estimated three-year progression-free survival rate was 24% (95% CI, 19.4%-28.8%) for the combination arm and 10% (95% CI, 5.9%-14.5%) for the vemurafenib monotherapy arm[1].

"We are pleased to see the continued benefit of Tafinlar + Mekinist targeted combination therapy beyond three-years in another study," said Alessandro Riva, MD, Global Head, Oncology Development & Medical Affairs. "As we’ve come to understand, this combination of targeted inhibitors has demonstrated an unprecedented ability to block the known resistance pathways and extend overall survival for BRAF mutation-positive patients. These results underscore our commitment to advancing the practice of precision oncology and extending patients’ lives through treatment options that target the root cause of their cancer."

At three years of follow up, the combination of Tafinlar + Mekinist continued to demonstrate a benefit on the measures of duration of response (DoR) and overall response rate (ORR), in line with results seen at the two-year follow up analysis[1].

The safety results were consistent with the profile observed to date for the combination and consistent with the profile observed for vemurafenib monotherapy; no new safety concerns were observed.

About the COMBI-v Study
COMBI-v is a two-arm, open-label, Phase III study comparing the combination of Tafinlar + Mekinist with vemurafenib monotherapy in patients with BRAF V600E/K mutation-positive unresectable or metastatic melanoma. The primary endpoint of this study was OS. The Independent Data Monitoring Committee (IDMC) stopped the trial early based on efficacy results observed in the Tafinlar + Mekinist study arm as part of a planned interim analysis[1].

About Melanoma
Advanced melanoma is the most serious and life-threatening type of skin cancer and is associated with low survival rates[2],[3]. Only about 20% of people will survive for at least five years following a diagnosis with late-stage disease[2]. There are about 200,000 new cases of melanoma diagnosed worldwide each year[4], approximately half of which have BRAF mutations, a key target in the treatment of metastatic melanoma[2],[5]. Gene tests can determine whether a tumor has a BRAF mutation[2],[6].

About Tafinlar + Mekinist Combination
Combination use of Tafinlar + Mekinist in patients with unresectable or metastatic melanoma who have a BRAF V600 mutation is approved in the US, EU, Australia, Canada and other countries.

Tafinlar and Mekinist target different kinases within the serine/threonine kinase family – BRAF and MEK1/2, respectively – in the RAS/RAF/MEK/ERK pathway, which is implicated in non-small cell lung cancer (NSCLC) and melanoma, among other cancers. When Tafinlar is used with Mekinist, the combination has been shown to slow tumor growth more than either drug alone. The combination of Tafinlar + Mekinist is currently being investigated in an ongoing clinical trial program across a range of tumor types conducted in study centers worldwide.

The safety and efficacy profile of the Tafinlar + Mekinist combination has not yet been established outside of the approved indication.

Tafinlar and Mekinist are also indicated in more than 40 countries worldwide, including the US and EU, as single agents to treat patients with unresectable or metastatic melanoma with a BRAF V600 mutation.

Tafinlar + Mekinist Combination Important Safety Information for Metastatic Melanoma
Tafinlar + Mekinist combination may cause serious side effects.

Tafinlar in combination with Mekinist should only be used to treat melanoma with a change (mutation) in the BRAF gene; therefore, doctors should test their patients before treatment, as patients without a BRAF mutation and with a RAS mutation can be at risk of increased cell proliferation in the presence of a BRAF inhibitor.

Doctors should also consider other treatment options for their patients if they had been previously treated with a BRAF inhibitor as single agent, as the limited data available have shown that the efficacy of Tafinlar + Mekinist is lower in these patients.

When Tafinlar is used in combination with Mekinist, or when Tafinlar is administered as monotherapy, it can cause new cancers (both skin cancer and non-skin cancer). Patients should be advised to contact their doctor immediately for any new lesions, changes to existing lesions on their skin, or signs and symptoms of other malignancies.

Tafinlar in combination with Mekinist, or Mekinist alone, can cause severe bleeding, and in some cases can lead to death. Patients should be advised to call their healthcare provider and get medical help right away if they have headaches, dizziness, or feel weak, cough up blood or blood clots, vomit blood or their vomit looks like "coffee grounds," have red or black stools that look like tar, or any unusual signs of bleeding.

Tafinlar in combination with Mekinist, or either drug alone, can cause severe eye problems that can lead to blindness. Patients should be advised to call their healthcare provider right away if they get these symptoms of eye problems: blurred vision, loss of vision, or other vision changes, seeing color dots, halo (seeing blurred outline around objects), eye pain, swelling, or redness.

Tafinlar in combination with Mekinist, or Tafinlar alone, can cause fever which may be serious. When taking Tafinlar in combination with Mekinist, fever may happen more often or may be more severe. In some cases, chills or shaking chills, too much fluid loss (dehydration), low blood pressure, dizziness, or kidney problems may happen with the fever. Patients should be advised to call their healthcare provider right away if they get a fever above 38.5oC (101.3oF) while taking Tafinlar.

Tafinlar in combination with Mekinist, or Mekinist alone, can affect how well the heart pumps blood. A patient’s heart function should be checked before and during treatment. Patients should be advised to call their healthcare provider right away if they have any of the following signs and symptoms of a heart problem: feeling like their heart is pounding or racing, shortness of breath, swelling of their ankles and feet, or feeling lightheaded.

Tafinlar in combination with Mekinist, or Tafinlar alone, can cause abnormal kidney function or inflammation of the kidney. Abnormal kidney function may happen more often for patients with fever or too much fluid loss. Patients should be advised to call their healthcare provider right away if they have a fever above 38.5oC (101.3oF), decreased urine, fatigue, loss of appetite or discomfort in lower abdomen or back. Tafinlar has not been studied in patients with renal insufficiency (defined as creatinine > 1.5 x ULN) therefore caution should be used in this setting.

Tafinlar in combination with Mekinist, or Mekinist alone, can cause abnormal liver function. A patient may feel tired, lose appetite, yellow skin, dark urine colour, or discomfort in abdomen. The liver function abnormality needs to be assessed by laboratory test of the blood. Patients should consult their healthcare provider if they have such experience. Administration of Tafinlar or Mekinist should be done with caution in patients with moderate to severe hepatic impairment.

Elevations in blood pressure have been reported in association with Mekinist in combination with Tafinlar, or with Mekinist alone, in patients with or without pre-existing hypertension. Patients should be advised to monitor blood pressure during treatment with Mekinist and control potential hypertension by standard therapy, as appropriate.

Tafinlar in combination with Mekinist, or Mekinist alone, can cause inflammation of the lung tissue. Patients should notify their doctor if they experience any new or worsening symptoms of lung or breathing problems, including shortness of breath or cough.

Rash is a common side effect of Tafinlar in combination with Mekinist, or with Mekinist alone. Tafinlar in combination with Mekinist, or Mekinist alone, can also cause other skin reactions which can be severe, and may need to be treated in a hospital. Patients should be advised to call their healthcare provider if they get any of the following symptoms: skin rash that bothers them or does not go away, acne, redness, swelling, peeling, or tenderness of hands or feet, skin redness.

Tafinlar in combination with Mekinist, or Mekinist alone, can cause muscle breakdown, a condition called Rhabdomyolysis. Patients experiencing muscle pain, tenderness, weakness or a swelling of their muscles should contact their healthcare provider immediately.

Tafinlar in combination with Mekinist, or Tafinlar alone, can uncommonly cause an inflammation of the pancreas (pancreatitis). Patients should be promptly investigated if they experience unexplained abdominal pain and closely monitored if they re-start Tafinlar after a prior episode of pancreatitis.

Tafinlar in combination with Mekinist, or Mekinist alone, can cause blood clots in the arms or legs, which can travel to the lungs and can lead to death. Patients should be advised to get medical help right away if they have the following symptoms: chest pain, sudden shortness of breath or trouble breathing, pain in their legs with or without swelling, swelling in their arms or legs, or a cool or pale arm or leg.

Mekinist, alone or in combination with Tafinlar, may increase the risk of developing holes in the stomach or intestine (gastrointestinal perforation). Treatment with Mekinist alone or in combination with Tafinlar should be used with caution in patients with risk factors for gastrointestinal perforation, including concomitant use of medications with a recognised risk of gastrointestinal perforation.

Tafinlar and Mekinist both can cause harm to an unborn baby when taken by a pregnant woman. Tafinlar can also render hormonal contraceptives ineffective.

The most common side effects of Tafinlar + Mekinist combination include fever, tiredness, nausea, headache, chills, diarrhea, rash, joint pain, high blood pressure, vomiting and cough. The incidence and severity of fever is increased when Mekinist is used in combination with Tafinlar. Patients should tell their doctor of any side effect that bothers them or does not go away. These are not all of the possible side effects of Tafinlar + Mekinist combination. For more information, patients should ask their doctor or pharmacist.

Patients should take Tafinlar + Mekinist combination exactly as their health care provider tells them. Patients should not change their dose or stop taking Tafinlar + Mekinist combination unless their health care provider advises them to. Mekinist should be taken only once daily (either in the morning or evening, at the same time as Tafinlar). The first and second doses of Tafinlar should be taken approximately 12 hours apart. Patients should take Tafinlar + Mekinist at least 1 hour before or 2 hours after a meal. Do not take a missed dose of Tafinlar within 6 hours of the next dose of Tafinlar. Do not open, crush, or break Tafinlar capsules. Do not take a missed dose of Mekinist within 12 hours of the next dose of Mekinist.

On October 8, 2016 AstraZeneca reported data from the Phase III FALCON trial demonstrating superior median progression-free survival (PFS) for Faslodex (fulvestrant) 500mg compared to Arimidex (anastrozole) 1mg in the 1st line treatment of postmenopausal women with locally-advanced or metastatic breast cancer (Press release, AstraZeneca, OCT 8, 2016, View Source [SID:SID1234515667]). The primary endpoint was PFS, and the FALCON trial enrolled 462 patients.1

The results, announced at the 2016 European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress, show that median PFS was 2.8 months longer with fulvestrant than anastrozole (Hazard ratio: 0.797; 95% confidence interval: 0.637-0.999; p=0.0486). The median PFS was 16.6 months in the fulvestrant arm compared, with 13.8 months in the anastrozole arm.1 Aromatase inhibitors, such as anastrozole, are the current standard of care in 1st line treatment for postmenopausal women with hormone-receptor positive (HR+) advanced breast cancer.2,3,4

Professor Matthew Ellis, Principal Investigator of the FALCON trial, said: "These data document a benefit for fulvestrant in delaying disease progression as a 1st line therapy, an important goal for women with metastatic breast cancer. The results are supported by a previous trial which also showed an advantage for fulvestrant over anastrozole. The results are clinically meaningful and suggest that fulvestrant could be a 1st line therapy for women with advanced breast cancer."

The safety and tolerability profile was in line with current experience with fulvestrant and anastrozole. The most commonly reported adverse events (AEs) in the fulvestrant and anastrozole arms were arthralgia (16.7% vs. 10.3%), hot flush (11.4% vs. 10.3%), and nausea (10.5% vs. 10.3%), respectively.

Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: "Fulvestrant has over 10 years of clinical evidence to support its use, and we are continuing to evaluate its full potential in advanced breast cancer, where we believe patient need is currently the greatest. AstraZeneca has a long, rich heritage in breast cancer research, and we remain committed to investigating innovative potential medicines for the treatment of women with all types of advanced disease."

About FALCON

The FALCON (Fulvestrant and AnastrozoLe COmpared in hormonal therapy Naïve advanced breast cancer) trial is a Phase III, randomised, double-blind, multicentre trial. It compared the antitumour effects and tolerability profile of a 500mg dose of fulvestrant plus placebo with a 1mg dose of anastrozole plus placebo, in postmenopausal women with HR+, locally-advanced or metastatic breast cancer who had not been treated previously with any hormonal therapy.

The FALCON trial was designed on the basis of positive results from the Phase II FIRST trial, which demonstrated a median overall survival nearly six months longer with fulvestrant compared to anastrozole.4

About Advanced Breast Cancer

Advanced/metastatic breast cancer refers to Stages III and IV breast cancer. Stage III disease may be referred to as locally-advanced breast cancer. Metastatic breast cancer is the most advanced stage of breast cancer (Stage IV), and occurs when cancer cells have spread beyond the initial tumour site to other parts of the body outside the breast. Since there is no cure for the disease, the goal of current treatment is to delay disease progression.5

About Fulvestrant

Fulvestrant is indicated for the treatment of postmenopausal women with oestrogen receptor-positive (ER+), locally-advanced or metastatic breast cancer for disease relapse on or after adjuvant anti-oestrogen therapy, or disease progression on therapy with an anti-oestrogen.2

In the US, fulvestrant is also approved, in combination with palbociclib, for the treatment of women with HR+, HER2- advanced or metastatic breast cancer, whose cancer has progressed after endocrine therapy.3 Fulvestrant represents a hormonal therapy approach that helps to slow tumour growth by blocking and degrading the oestrogen receptor – a key driver of disease progression.3,6

On October 8, 2016 Merck (NYSE:MRK), known as MSD outside the United States and Canada, reported positive findings from the phase 2 KEYNOTE-052 study investigating the use of KEYTRUDA (pembrolizumab), the company’s anti-PD-1 therapy, in previously untreated patients with unresectable (inoperable) or metastatic urothelial cancer who are ineligible for cisplatin-based therapy. Data presented at the ESMO (Free ESMO Whitepaper) 2016 Congress, the annual meeting of the European Society for Medical Oncology, showed an overall response rate (ORR) of 24 percent (n=24/100) (95% CI, 16-34) in the total study population, which included patients with and without PD-L1 expression.

"We have a growing body of evidence of KEYTRUDA’s activity in a range of cancers and treatment settings including the first-line treatment of patients with advanced urothelial cancer who will not tolerate cisplatin-based therapy," said Dr. Roger Dansey, senior vice president, oncology late-stage development, Merck Research Laboratories.

The KEYTRUDA clinical development program includes more than 30 tumor types in more than 350 clinical studies, including more than 100 trials that combine KEYTRUDA with other cancer treatments. Merck has the largest immuno-oncology clinical development program in bladder cancer with 27 trials involving KEYTRUDA, including four registration-enabling studies currently underway.

"There have been very few advancements in the treatment of bladder cancer in the past several decades, and patients with urothelial cancer who are ineligible for cisplatin-based therapy are in significant need of new approaches to care," said Dr. Dean F. Bajorin, study investigator and medical oncologist at Memorial Sloan Kettering Cancer Center. "These data are exciting and demonstrate the potential for an anti-PD-1 therapy, such as pembrolizumab, to address the unmet treatment need that exists today for cisplatin-ineligible patients with this type of urothelial cancer."

Findings from KEYNOTE-052 are being presented at the ESMO (Free ESMO Whitepaper) 2016 Congress by Dr. Arjun V. Balar, medical oncologist and assistant professor of medicine at the Perlmutter Cancer Center at NYU Langone Medical Center, on Oct. 8 from 9:30 – 9:45 a.m. CEST (Abstract: # LBA32_PR) and are featured in the official ESMO (Free ESMO Whitepaper) press program.

Additional Findings from KEYNOTE-052

KEYNOTE-052 is an open-label, phase 2 study evaluating KEYTRUDA (pembrolizumab) (200 mg every three weeks) monotherapy as a first-line treatment in an estimated 350 patients with unresectable (inoperable) or metastatic urothelial cancer (a type of bladder cancer) who are ineligible for cisplatin-based therapy. The primary endpoints include ORR in all patients enrolled in the study (total study population) and in patients with PD-L1 positive tumors (expression of one percent or more). Secondary endpoints include duration of response, progression-free survival (PFS), and overall survival (OS). Tumor response was measured according to RECIST (Response Evaluation Criteria in Solid Tumors) v1.1 as assessed by blinded independent central review.

Findings presented at the ESMO (Free ESMO Whitepaper) 2016 Congress are from the planned interim analysis of the first 100 patients, which was intended to evaluate ORR and determine the PD-L1-high expression cut-point as examined by expression in tumor and immune cells. Forty-five percent of patients (n=45/100) had an ECOG (Eastern Cooperative Oncology Group) Performance Status (PS) score of two, 30 percent (n=30/100) had a PS score of one, and 24 percent (n=24/100) had a PS score of zero.

In the total study population, ORR was 24 percent (n=24/100) (95% CI, 16-34) with a complete response rate of six percent (n=6/100) (95% CI, 2-13). Review of the outcomes based on PD-L1 expression showed that in patients with PD-L1 expression of less than one percent, ORR was 18 percent (n=6/33) (95% CI, 7-36) with a complete response rate of three percent (n=1/33) (95% CI, 0.1-16); in patients with PD-L1 expression greater than or equal to one percent and less than 10 percent, ORR was 15 percent (n=5/33) (95% CI, 5-32) with no complete responses; and, in patients expressing PD-L1 at levels equal to or greater than 10 percent, ORR was 37 percent (n=11/30) (95% CI, 20-56) with a complete response rate of 13 percent (n=4/30) (95% CI, 4-31). Among the 24 percent of patients in the total study population who were responding to treatment, the median duration of response had not been reached (range 1.4+ to 9.8+ months), with 83 percent of patients (n=20/24) having responses of six months or longer.

The safety profile of KEYTRUDA (pembrolizumab) was consistent with that observed in previously reported KEYTRUDA studies. The treatment-related adverse events observed in this trial (any grade occurring in five percent or more of patients) were fatigue (n=14), pruritus (n=12), pyrexia (n=8), decreased appetite (n=7), diarrhea (n=7), rash (n=7), chills (n=6), hypothyroidism (n=6), and nausea (n=6). Grade 3-4 treatment-related adverse events observed (occurring in 2 or more patients) were fatigue (n=4), muscle spasms (n=2), decreased appetite (n=1), and diarrhea (n=1). Immune-mediated adverse events of Grade 3-4 were nephritis (n=1) and pneumonitis (n=2). Five patients discontinued due to a treatment-related adverse event; there were no treatment-related deaths.

On October 8, 2016 TESARO, Inc. (NASDAQ:TSRO), an oncology-focused biopharmaceutical company, and ENGOT, the European Network for Gynaecological Oncological Trial groups, reported the presentation of the niraparib Phase 3 ENGOT-OV16/NOVA clinical trial results at the ESMO (Free ESMO Whitepaper) 2016 Congress, the congress of the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper), by Dr. Mansoor Raza Mirza, M.D., Medical Director of the Nordic Society of Gynecologic Oncology (NSGO) and principal investigator on the ENGOT-OV16/NOVA trial (Press release, TESARO, OCT 8, 2016, View Source [SID:SID1234515655]). These data were discussed during the ESMO (Free ESMO Whitepaper) press briefing in Copenhagen as part of the congress, and were simultaneously published online in the New England Journal of Medicine.1 The results will also be presented by Dr. Mirza later today during Presidential Symposium 1 (Abstract #LBA3_PR) at ESMO (Free ESMO Whitepaper).

ENGOT-OV16/NOVA is a double-blind, placebo-controlled, international Phase 3 trial of niraparib that enrolled 553 patients with recurrent ovarian cancer who were in response to their most recent platinum-based chemotherapy. This trial was designed to assess progression free survival (PFS) in a broad population of patients who were assigned to one of two cohorts based upon germline BRCA mutation status. The ENGOT-OV16/NOVA trial successfully achieved its primary endpoint in both cohorts, demonstrating that niraparib treatment significantly prolonged PFS compared to control in patients who were germline BRCA mutation (gBRCAmut) carriers and in patients who were not germline BRCA mutation (non-gBRCAmut) carriers. In addition, within the non-gBRCA cohort, niraparib treatment significantly prolonged PFS compared to control for the prospectively defined patient population with tumors deficient in homologous recombination (HRDpos) as determined by the Myriad myChoice HRD test. A high proportion of patients in both treatment groups in both cohorts had received three or more prior lines of chemotherapy.

"These landmark results are extremely encouraging for the ovarian cancer community," said Dr. Mirza. "The effectiveness of platinum-based chemotherapy diminishes over time, and PFS and platinum-free intervals generally become shorter after each round of platinum treatment. In addition, the incidence of infection and risk of neuropathy and hypersensitivity with certain chemotherapy agents rises with subsequent cycles. An oral maintenance treatment that could lengthen the PFS interval between rounds of platinum-based chemotherapy would be very meaningful for patients with ovarian cancer, who often live with a fear of recurrence after ending active treatment."

"We would like to thank the patients, their families and the caregivers that participated in the ENGOT-OV16/NOVA study, as well as our partners at ENGOT for their diligence in executing this trial," said Mary Lynne Hedley, Ph.D., President and COO of TESARO. "We believe the results of this Phase 3 study demonstrated a meaningful benefit for women with platinum sensitive, recurrent ovarian cancer."

Primary Endpoint Results:

Statistically Significant PFS Results in the gBRCAmut Cohort
Among patients who were germline BRCA mutation carriers, the niraparib arm successfully achieved statistical significance over the control arm for the primary endpoint of PFS, with a hazard ratio of 0.27 (95% CI, 0.173-0.410). The median PFS for patients treated with niraparib was 21.0 months, compared to 5.5 months for control (p<0.0001).

Statistically Significant PFS Results in the non-gBRCAmut Cohort
Niraparib showed statistical significance for patients in the non-germline BRCA mutant cohort. The niraparib arm successfully achieved statistical significance over the control arm for the primary endpoint of PFS, with a hazard ratio of 0.45 (95% CI, 0.338-0.607). The median PFS for patients treated with niraparib was 9.3 months, compared to 3.9 months for control (p<0.0001).

Statistically Significant PFS Results in non-gBRCAmut Cohort for Patients with HRD-Positive Tumors
For patients who were not germline BRCA mutation carriers but whose tumors were determined to be HRD positive using the Myriad myChoice HRD test, the niraparib arm successfully achieved statistical significance over the control arm for the primary endpoint of PFS, with a hazard ratio of 0.38 (95% CI, 0.243-0.586). The median PFS for patients with HRD-positive tumors who were treated with niraparib was 12.9 months, compared to 3.8 months for control (p<0.0001).

Secondary Endpoint Results:

Secondary endpoint analyses, including chemotherapy-free interval, time to first subsequent treatment, and PFS 2 were all statistically significant and favored niraparib over control for patients in both the gBRCAmut and non-gBRCAmut cohorts. Patient-reported outcome results from validated survey tools indicated that niraparib-treated patients reported no difference from control in measures associated with quality of life. Data for overall survival are immature (HR 0.73; 95% CI, 0.480 to 1.125; p=0.1545), as fewer than 20% of events had occurred at the time of analysis.

Safety Results:

The most common (≥10%) treatment-emergent grade 3/4 adverse events in the niraparib arm were thrombocytopenia (33.8%), anemia (25.3%), and neutropenia (19.6%) with treatment discontinuation for these events of 3.3%, 1.4% and 1.9%, respectively. Thrombocytopenia was not associated with grade 3/4 bleeding events. The majority of these hematological laboratory abnormalities occurred within the first three cycles; following dose modifications the incidence of these lab abnormalities decreased and thrombocytopenia and neutropenia were infrequent beyond cycle 3. The rates of MDS/AML in the niraparib (1.4%) and control (1.1%) arms were similar. There were no deaths among patients during study treatment.

"Despite diagnostic and treatment advances, ovarian cancer remains the deadliest gynecologic cancer, and the need for new therapeutic options that prolong response remains critical," said David Barley, CEO of the National Ovarian Cancer Coalition. "The results of the NOVA trial are encouraging, and could offer patients and their families a treatment option during the stressful period that follows platinum-based chemotherapy where the majority of patients receive no treatment."

About the Phase 3 ENGOT-OV16/NOVA Clinical Trial of Niraparib
NOVA is a double-blind, placebo-controlled, international Phase 3 trial of niraparib that enrolled 553 patients with recurrent ovarian cancer who were in a response to their most recent platinum-based chemotherapy. Patients were enrolled into one of two independent cohorts based on germline BRCA mutation status. One cohort enrolled patients who were germline BRCA mutation carriers (gBRCAmut), and the second cohort enrolled patients who were not germline BRCA mutation carriers (non-gBRCAmut) and included patients with HRD-positive and HRD-negative tumors. Within each cohort, patients were randomized 2:1 to receive niraparib or placebo and were treated continuously with placebo or 300 milligrams of niraparib, dosed as three 100 milligram tablets once per day, until progression. The primary endpoint of this study was progression-free survival (PFS). Secondary endpoints include patient-reported outcomes, chemotherapy-free interval length, PFS 2, overall survival, and other measures of safety and tolerability.

About Niraparib
Niraparib is an oral, once-daily PARP inhibitor that is currently being evaluated in four ongoing pivotal trials. TESARO is building a robust niraparib franchise by assessing activity across multiple tumor types and by evaluating several potential combinations of niraparib with other therapeutics. The ongoing development program for niraparib includes a Phase 3 trial in patients with platinum-sensitive, recurrent ovarian cancer (the NOVA trial); a Phase 3 trial in patients with first-line ovarian cancer (the PRIMA trial); a registrational Phase 2 treatment trial in patients with ovarian cancer (the QUADRA trial); and a Phase 3 trial for the treatment of patients with BRCA-mutant breast cancer (the BRAVO trial). Several combination studies are also underway, including trials of niraparib plus pembrolizumab and bevacizumab. Janssen Biotech has licensed rights to develop and commercialize niraparib specifically for patients with prostate cancer worldwide, except in Japan.

The U.S. Food and Drug Administration (FDA) has granted Fast Track designation to niraparib for the treatment of patients with recurrent platinum-sensitive ovarian, fallopian tube, or primary peritoneal cancer. TESARO has initiated a rolling submission of a New Drug Application (NDA) for niraparib to the FDA, and intends to complete this submission during the fourth quarter. The Marketing Authorization Application (MAA) for niraparib is planned for submission to the European Medicines Agency (EMA) in the fourth quarter.

Niraparib is an investigational agent and, as such, has not been approved by the U.S. FDA, the European Medicines Agency (EMA), or any other regulatory agencies.

About Ovarian Cancer
Approximately 22,000 women are diagnosed each year with ovarian cancer in the United States, and more than 65,000 women are diagnosed annually in Europe. Ovarian cancer is the fifth most frequent 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 will experience recurrence within two years. If approved, niraparib may address the difficult "watchful waiting" periods experienced by patients with recurrent ovarian cancer in between cycles of platinum-based chemotherapy.

On October 8, 2016 Bristol-Myers Squibb Company (NYSE:BMY) reported results from the CheckMate -275 trial, in which Opdivo had a confirmed objective response rate (ORR), the primary endpoint, of 19.6% (95% CI: 15.0 – 24.9) in platinum-refractory patients with metastatic urothelial carcinoma (Press release, Bristol-Myers Squibb, OCT 8, 2016, View Source [SID:SID1234515653]). Responses were observed in both PD-L1 expressors and non-expressors. The confirmed ORR in patients expressing PD-L1 ≥1% was 23.8% (95% CI: 16·5 – 32·3) and 16.1% (95% CI: 10.5 – 23.1) in patients expressing PD-L1 <1%. In patients expressing PD-L1 ≥5%, the confirmed ORR was 28.4% (95% CI: 18.9 – 39.5) and 15.8% (95% CI: 10.8 – 21.8) in patients expressing PD-L1 <5%. The median duration of response was not reached in the overall population with a minimum follow-up of six months, and responses were ongoing in 77% of patients. The safety profile of Opdivo in this study was consistent with the safety profile of Opdivo in other tumor types.

These data will be presented today, October 8, at the 2016 European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress during an oral proffered paper session from 9:15 – 9:30 a.m. CEST (Abstract #LBA31_PR).

"The prognosis for patients with metastatic urothelial carcinoma progressing despite platinum-based chemotherapy is poor, and treatment options have historically been quite limited," said Matthew Galsky, M.D., professor of medicine and director of Genitourinary Medical Oncology, The Tisch Cancer Institute at Icahn School of Medicine at Mount Sinai. "In the CheckMate -275 study, we observe that with Opdivo, patients who responded experienced rapid and durable responses, including patients with PD-L1 expressing and non-expressing tumors. These results are encouraging and provide new information to the scientific community on the potential of Opdivo as a treatment option for this type of advanced bladder cancer."

Urothelial carcinoma, a common type of bladder cancer, accounts for approximately 90% of cases. The majority of bladder cancers are diagnosed at an early stage, but approximately 78% of patients will experience a recurrence within five years.

Vicki Goodman, M.D., development lead, Melanoma and Genitourinary Cancers, Bristol-Myers Squibb, commented, "There is a significant unmet need for new treatment approaches for progressive metastatic urothelial carcinoma. The results from CheckMate -275 show treatment with Opdivo resulted in durable and clinically meaningful objective response of 19.6% in all-treated patients. Based on these findings, we believe Opdivo has the potential to become an important new treatment option for patients with platinum-refractory advanced bladder cancer."

About CheckMate -275

CheckMate -275 is a Phase 2, single-arm clinical trial evaluating the safety and efficacy of Opdivo in 270 patients with metastatic or unresectable urothelial carcinoma who have progressed or recurred following treatment with a platinum-based agent in the metastatic setting or within one year after neoadjuvant/adjuvant platinum therapy. The trial enrolled patients regardless of PD-L1 expression. The primary endpoint was confirmed objective response rate (ORR) based on assessments by the blinded independent review committee in all treated patients and in patients with tumor PD-L1 expression ≥1% and ≥5%. Key secondary endpoints included progression-free survival (PFS), overall survival (OS), safety and quality of life. Patients received Opdivo 3 mg/kg administered intravenously every two weeks and were assessed for response beginning eight weeks from randomization and continuing every eight weeks for 48 weeks, then every 12 weeks until progression or discontinuation.

The confirmed ORR was 19.6% (95% CI: 15.0 – 24.9) for all treated patients. About half of the overall patient population (46%) had a PD-L1 expression of ≥1%, and approximately 30% had a PD-L1 expression of ≥5%. Higher responses observed among patients with PD-L1 expression ≥1% (23.8%; 95% CI: 16.5 – 32.3) and ≥5% (28.4%; 95% CI: 18.9 – 39.5). Responses to Opdivo were also observed in patients with PD-L1 <1% (16.1%; 95% CI: 10.5 – 23.1) and <5% (15.8%; 95% CI: 10.8 – 21.8).

Among the 52 patients who responded to treatment, the median time to a response was 1.9 months (1.6 – 5.9 months). Median duration of response was not reached, with an ongoing response among 77% of the responders at the time of the analysis.

The median PFS was 2.0 months in all treated patients (95% CI: 1.87 – 2.63), 1.87 months for patients with PD-L1 <1% (95% CI: 1.77 – 2.04), and 3.55 months in patients with PD-L1 ≥1% (95% CI: 1.94 – 3.71). The median OS was 8.74 months in all treated patients (95% CI: 6.05 – N.A.), 5.95 months in patients with PD-L1 <1% (95% CI: 4.30 – 8.08), and 11.3 months in patients with PD-L1 expression ≥1% (95% CI: 8.74 – N.A.). In addition, quality of life is maintained for patients remaining on study over 41 weeks on two quality of life measures – the EORTC (European Organisation for Research and Treatment of Cancer) QLQ-C30 and the EQ-5D Visual Analog Scale.

The safety profile of Opdivo in CheckMate -275 was consistent with the safety profile of Opdivo in other tumor types. Among the 270 patients who received Opdivo, 64.4% experienced a treatment-related adverse event (AE) of any grade, with grade 3 or 4 in 17.8%. The most frequently reported treatment-related AEs of any grade included fatigue (16.7%), pruritis (9.3%), diarrhea (8.9%), decreased appetite (8.1%), hypothyroidism (7.8%), nausea (7.0%), asthenia (5.9%), rash (5.9%) and pyrexia (5.6%). The most frequent treatment-related grade 3-4 AEs were fatigue (1.9%), diarrhea (1.9%), asthenia (1.5%) and rash (1.1%). Overall, 4.8% of patients discontinued therapy due to treatment-related AEs of any grade, and 3.0% discontinued therapy due to grade 3-4 treatment-related AEs.

Bristol-Myers Squibb: At the Forefront of Immuno-Oncology Science & Innovation

At Bristol-Myers Squibb, patients are at the center of everything we do. Our vision for the future of cancer care is focused on researching and developing transformational Immuno-Oncology (I-O) medicines that will raise survival expectations in hard-to-treat cancers and will change the way patients live with cancer.

We are leading the scientific understanding of I-O through our extensive portfolio of investigational and approved agents – including the first combination of two I-O agents in metastatic melanoma – and our differentiated clinical development program, which is studying broad patient populations across more than 20 types of cancers with 11 clinical-stage molecules designed to target different immune system pathways. Our deep expertise and innovative clinical trial designs uniquely position us to advance the science of combinations across multiple tumors and potentially deliver the next wave of I-O combination regimens with a sense of urgency. We also continue to pioneer research that will help facilitate a deeper understanding of the role of immune biomarkers and inform which patients will benefit most from I-O therapies.

We understand making the promise of I-O a reality for the many patients who may benefit from these therapies requires not only innovation on our part but also close collaboration with leading experts in the field. Our partnerships with academia, government, advocacy and biotech companies support our collective goal of providing new treatment options to advance the standards of clinical practice.

About Opdivo

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol-Myers Squibb’s scientific expertise in the field of Immuno-Oncology and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has enrolled more than 25,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 57 countries, including the United States, the European Union and Japan. In October 2015, the company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 47 countries, including the United States and the European Union.

IMPORTANT SAFETY INFORMATION

WARNING: IMMUNE-MEDIATED ADVERSE REACTIONS

YERVOY can result in severe and fatal immune-mediated adverse reactions. These immune- mediated reactions may involve any organ system; however, the most common severe immune- mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. The majority of these immune-mediated reactions initially manifested during treatment; however, a minority occurred weeks to months after discontinuation of YERVOY.

Assess patients for signs and symptoms of enterocolitis, dermatitis, neuropathy, and endocrinopathy and evaluate clinical chemistries including liver function tests (LFTs), adrenocorticotropic hormone (ACTH) level, and thyroid function tests at baseline and before each dose.

Permanently discontinue YERVOY and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions.

In < 1.0% of patients receiving OPDIVO, the following clinically significant, immune-mediated adverse reactions occurred: uveitis, iritis, pancreatitis, facial and abducens nerve paresis, demyelination, polymyalgia rheumatica, autoimmune neuropathy, Guillain-Barré syndrome, hypopituitarism, systemic inflammatory response syndrome, gastritis, duodenitis, and sarcoidosis. Across clinical trials of OPDIVO as a single agent administered at doses of 3 mg/kg and 10 mg/kg, additional clinically significant, immune- mediated adverse reactions were identified: motor dysfunction, vasculitis, and myasthenic syndrome.

Infusion Reactions

Severe infusion reactions have been reported in <1.0% of patients in clinical trials of OPDIVO. Discontinue OPDIVO in patients with Grade 3 or 4 infusion reactions. Interrupt or slow the rate of infusion in patients with Grade 1 or 2. In CheckMate 069 and 067, infusion- related reactions occurred in 2.5% (10/407) of patients receiving OPDIVO with YERVOY: Grade 2 (n=6) and Grade 1 (n=4). In CheckMate 037, 066, and 067, Grade 2 infusion related reactions occurred in 2.7% (21/787) of patients receiving OPDIVO: Grade 3 (n=2), Grade 2 (n=8), and Grade 1 (n=11). In CheckMate 057, Grade 2 infusion reactions requiring corticosteroids occurred in 1.0% (3/287) of patients receiving OPDIVO. In CheckMate 025, hypersensitivity/infusion-related reactions occurred in 6% (25/406) of patients receiving OPDIVO and 1.0% (4/397) of patients receiving everolimus. In CheckMate 205 and 039, hypersensitivity/infusion- related reactions occurred in 16% (42/263) of patients receiving OPDIVO: Grade 3 (n=2), Grade 2 (n=24), and Grade 1 (n=16).

Complications of Allogeneic HSCT after OPDIVO

Complications, including fatal events, occurred in patients who received allogeneic HSCT after OPDIVO. Outcomes were evaluated in 17 patients from CheckMate 205 and 039, who underwent allogeneic HSCT after discontinuing OPDIVO (15 with reduced-intensity conditioning, 2 with myeloablative conditioning). Thirty-five percent (6/17) of patients died from complications of allogeneic HSCT after OPDIVO. Five deaths occurred in the setting of severe or refractory GVHD. Grade 3 or higher acute GVHD was reported in 29% (5/17) of patients. Hyperacute GVHD was reported in 20% (n=2) of patients. A steroid-requiring febrile syndrome, without an identified infectious cause, was reported in 35% (n=6) of patients. Two cases of encephalitis were reported: Grade 3 (n=1) lymphocytic encephalitis without an identified infectious cause, and Grade 3 (n=1) suspected viral encephalitis. Hepatic veno-occlusive disease (VOD) occurred in one patient, who received reduced-intensity conditioned allogeneic SCT and died of GVHD and multi-organ failure. Other cases of hepatic VOD after reduced-intensity conditioned allogeneic HSCT have also been reported in patients with lymphoma who received a PD-1 receptor blocking antibody before transplantation. Cases of fatal hyperacute GVHD have also been reported. These complications may occur despite intervening therapy between PD-1 blockade and allogeneic HSCT.

Follow patients closely for early evidence of transplant-related complications such as hyperacute GVHD, severe (Grade 3 to 4) acute GVHD, steroid-requiring febrile syndrome, hepatic VOD, and other immune- mediated adverse reactions, and intervene promptly.

Embryo-fetal Toxicity

Based on their mechanisms of action, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with an OPDIVO- or YERVOY- containing regimen and for at least 5 months after the last dose of OPDIVO.

Lactation

It is not known whether OPDIVO or YERVOY is present in human milk. Because many drugs, including antibodies, are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from an OPDIVO-containing regimen, advise women to discontinue breastfeeding during treatment. Advise women to discontinue nursing during treatment with YERVOY and for 3 months following the final dose.

Serious Adverse Reactions

In CheckMate 067, serious adverse reactions (73% and 37%), adverse reactions leading to permanent discontinuation (43% and 14%) or to dosing delays (55% and 28%), and Grade 3 or 4 adverse reactions (72% and 44%) all occurred more frequently in the OPDIVO plus YERVOY arm relative to the OPDIVO arm. The most frequent (≥10%) serious adverse reactions in the OPDIVO plus YERVOY arm and the OPDIVO arm, respectively, were diarrhea (13% and 2.6%), colitis (10% and 1.6%), and pyrexia (10% and 0.6%). In CheckMate 037, serious adverse reactions occurred in 41% of patients receiving OPDIVO. Grade 3 and 4 adverse reactions occurred in 42% of patients receiving OPDIVO. The most frequent Grade 3 and 4 adverse drug reactions reported in 2% to <5% of patients receiving OPDIVO were abdominal pain, hyponatremia, increased aspartate aminotransferase, and increased lipase.
