Pfizer Presents Overall Survival Data of XALKORI in Patients with ALK-Positive Advanced Non-Small Cell Lung Cancer

NEW YORK--(BUSINESS WIRE)--Pfizer Inc. (NYSE:PFE) today announced final overall survival (OS) data from the PROFILE 1014 trial examining XALKORI® (crizotinib) in previously untreated patients with ALK-positive advanced non-small cell lung cancer(NSCLC). After a median follow-up of 46 months, the median OS for patients randomized to XALKORI was not reached (95% CI: 45.8 months, not reached) and was 47.5 months for patients randomized to chemotherapy (95% CI: 32.2 months, not reached). Results indicated a numerical improvement in OS for patients treated with first-line XALKORI compared with chemotherapy, though this difference did not quite achieve statistical significance (HR=0.760 [95% CI: 0.548, 1.053]; p=0.0978). These data [Abstract #LBA50] were presented today at the 2017 European Society for Medical Oncology (ESMO) Congress in Madrid, Spain.

"If approved for this indication, tofacitinib could potentially be an important new oral treatment option for people living with UC."

NEW YORK--(BUSINESS WIRE)--Pfizer Inc. (NYSE:PFE) announced today that detailed results from the Phase 3 Oral Clinical Trials for tofAcitinib in ulceratiVE colitis (OCTAVE) clinical program were published in The New England Journal of Medicine (NEJM).

Data from all three pivotal Phase 3 studies – OCTAVE Induction 1, OCTAVE Induction 2 and OCTAVE Sustain – met their respective primary endpoints, demonstrating that tofacitinib citrate was more effective than placebo in inducing and maintaining remission in patients with moderate to severe ulcerative colitis (UC).1a,1b Remission was defined as a Mayo score* of 2 points or lower, with no individual subscore exceeding 1 point, and a rectal bleeding subscore of 0.1c

“The publication of results from the full Phase 3 OCTAVE clinical program is a significant milestone,” said William J. Sandborn, MD, Chief, Division of Gastroenterology, Professor of Medicine at the University of California San Diego School of Medicine and study investigator. “This robust data set provides evidence that tofacitinib, if approved, could be an important new oral treatment option with the potential to help patients with moderate to severe active ulcerative colitis achieve and maintain remission.”

__________

*Mayo score is a measurement index comprised of four categories (stool frequency, rectal bleeding, findings on endoscopy, physician global assessment) that are each rated from 0 (normal) to 3 (most severe) for a total score that ranges from 0-12.

OCTAVE Induction 1 & 2

OCTAVE Induction 1 and OCTAVE Induction 2 each evaluated induction of remission by oral tofacitinib 10 mg twice-daily (BID) compared to placebo in adult patients with moderate to severe UC.1d The studies enrolled 598 and 541 patients, respectively.1dEligible patients were randomly assigned to receive eight weeks of therapy with oral tofacitinib 10 mg BID (476 and 429 patients, respectively) or placebo (122 and 112 patients, respectively).1e,1f

In OCTAVE Induction 1, a statistically significant and greater proportion of patients receiving tofacitinib 10 mg BID (18.5%) were in remission at Week 8, compared to 8.2% receiving placebo (p=0.007).1g Similar results were observed in OCTAVE Induction 2, with 16.6% of patients receiving tofacitinib 10 mg BID achieving remission at Week 8, compared to 3.6% receiving placebo (p<0.001).1h

In addition, across each study, a statistically significant and greater proportion of patients receiving tofacitinib 10 mg BID achieved the key secondary endpoint of mucosal healing at Week 8, including 31.3% of patients compared to 15.6% receiving placebo in OCTAVE Induction 1, and 28.4% of patients compared to 11.6% receiving placebo in OCTAVE Induction 2 (p<0.001 across both studies).1i,1j

OCTAVE Sustain

The OCTAVE Sustain study evaluated the efficacy of tofacitinib as maintenance therapy compared to placebo in adult patients with moderate to severe UC.1k It included patients who had completed one of the OCTAVE Induction studies and had achieved at least clinical response (≥3 points reduction and ≥30% decrease from baseline Mayo score plus a decrease in rectal bleeding subscore of ≥1 or absolute rectal bleeding subscore ≤1).1l A total of 593 participants were randomized to receive maintenance treatment with tofacitinib 5 mg BID (198 patients), tofacitinib 10 mg BID (197 patients) or placebo (198 patients) for 52 weeks.1m

In OCTAVE Sustain, 34.3% and 40.6% of patients achieved remission at Week 52 with tofacitinib 5 mg BID and tofacitinib 10 mg BID, respectively, compared to 11.1% taking placebo (p<0.001).1n In addition, both doses of tofacitinib met the key secondary endpoints of the study, mucosal healing and sustained steroid-free remission among baseline remitters.1o Across tofacitinib 5 mg BID, tofacitinib 10 mg BID and placebo arms, mucosal healing was achieved by 37.4%, 45.7% and 13.1% of patients (p<0.001), respectively, and sustained steroid-free remission was achieved by 35.4%, 47.3% and 5.1% (p<0.001), respectively.1o

“Ulcerative colitis is a debilitating disease that affects all aspects of patients’ lives. We are pleased to share the results of this promising clinical trial of tofacitinib as part of our efforts to improve the lives of patients through our research with Janus kinase inhibitors," said Michael Corbo, PhD, Chief Development Officer, Inflammation & Immunology, Global Product Development, Pfizer, Inc. "If approved for this indication, tofacitinib could potentially be an important new oral treatment option for people living with UC.”

During the OCTAVE Induction studies, overall infection and serious infection rates were higher with tofacitinib than placebo.1p In OCTAVE Induction 1, 23.3% and 1.3% of patients receiving tofacitinib 10 mg BID had infections and serious infections, respectively, compared to 15.6% and 0 receiving placebo.1p In OCTAVE Induction 2, 18.2% and 0.2% of patients receiving tofacitinib 10 mg BID had infections and serious infections, respectively, compared to 15.2% and 0 receiving placebo.1p

During OCTAVE Sustain, serious infection rates were similar across treatment groups (1.0%, 0.5% and 1.0% across tofacitinib 5 mg BID, 10 mg BID and placebo groups, respectively).1q Overall infection rates were higher with tofacitinib than placebo (35.9%, 39.8% and 24.2% across tofacitinib 5 mg BID, 10 mg BID and placebo groups, respectively). Cases of herpes zoster were more frequently observed with tofacitinib 10 mg BID compared to other treatment groups (1.5%, 5.1% and 0.5% across tofacitinib 5 mg BID, 10 mg BID and placebo groups, respectively).1q

Across all studies, five tofacitinib-treated patients had adjudicated non-melanoma skin cancer, five had adjudicated cardiovascular events and there were increases in lipids with tofacitinib.1r,1s,1t,1u There were two cases of malignancy in the control groups limited to one case of non-melanoma skin cancer and one case of invasive ductal breast carcinoma during OCTAVE Sustain.1t

The manuscript of full study results, which indicate that tofacitinib citrate was more effective than placebo in inducing and maintaining remission in patients with moderate to severe active UC, is available at http://www.nejm.org/doi/full/10.1056/NEJMoa1606910.

About Ulcerative Colitis

UC is a chronic, often debilitating inflammatory bowel disease that affects millions of people worldwide.2,3 While the exact cause of UC is unknown, it is believed that UC is the result of complex interactions between multiple factors that include genetic predisposition and an exaggerated immune response to a microbial trigger.4 It can cause chronic diarrhea with blood and mucus, abdominal pain and cramping, fever and weight loss.5 UC can have a significant effect on work, family and social activities.6 In up to one-third of patients with UC, treatment is not completely successful or complications may arise.7 Under these circumstances, surgery to remove the colon (colectomy) may be considered.7

XELJANZ/XELJANZ XR is used to treat adults with moderately to severely active rheumatoid arthritis in which methotrexate did not work well. XELJANZ/XELJANZ XR may be used as a single agent or in combination with methotrexate (MTX) or other non-biologic disease-modifying antirheumatic drugs (DMARDs). Use of XELJANZ/XELJANZ XR in combination with biologic DMARDs or potent immunosuppressants, such as azathioprine and cyclosporine, is not recommended.

• It is not known if XELJANZ/XELJANZ XR is safe and effective in people with hepatitis B or C.
• XELJANZ/XELJANZ XR is not for people with severe liver problems.
• It is not known if XELJANZ/XELJANZ XR is safe and effective in children.

Important Safety Information

• XELJANZ/XELJANZ XR can lower the ability of the immune system to fight infections. Some people can have serious infections while taking XELJANZ/XELJANZ XR, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have died from these infections. Healthcare providers should test patients for TB before starting XELJANZ/XELJANZ XR, and monitor them closely for signs and symptoms of TB and other infections during treatment. People should not start taking XELJANZ/XELJANZ XR if they have any kind of infection unless their healthcare provider tells them it is okay.
• People may be at a higher risk of developing shingles.
• XELJANZ/XELJANZ XR may increase the risk of certain cancers by changing the way the immune system works. Lymphoma and other cancers, including skin cancers, can happen in patients taking XELJANZ/XELJANZ XR.
• The risks and benefits of treatment should be considered prior to initiating XELJANZ/XELJANZ XR in patients with chronic or recurrent infection; who have been exposed to tuberculosis; with a history of a serious or an opportunistic infection; who have resided or traveled in areas of endemic tuberculosis or endemic mycoses; or with underlying conditions that may predispose them to infection.
• Viral reactivation, including cases of herpes virus reactivation (e.g., herpes zoster), was observed in clinical studies with XELJANZ.
• Use of live vaccines should be avoided concurrently with XELJANZ/XELJANZ XR. Update immunizations in agreement with current immunization guidelines prior to initiating XELJANZ/XELJANZ XR therapy.
• Some people who have taken XELJANZ with certain other medicines to prevent kidney transplant rejection have had a problem with certain white blood cells growing out of control (Epstein Barr virus-associated post-transplant lymphoproliferative disorder).
• Some people taking XELJANZ/XELJANZ XR can get tears in their stomach or intestines. This happens most often in people who also take nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, or methotrexate.
• XELJANZ/XELJANZ XR should be used with caution in patients who may be at increased risk for gastrointestinal perforation (e.g., patients with a history of diverticulitis), or who have a narrowing within their digestive tract. Patients should tell their healthcare provider right away if they have fever and stomach-area pain that does not go away or a change in bowel habits.
• XELJANZ/XELJANZ XR can cause changes in certain lab test results including low blood cell counts, increases in certain liver tests, and increases in cholesterol levels. Healthcare providers should do blood tests before starting patients on XELJANZ/XELJANZ XR and while they are taking XELJANZ/XELJANZ XR, to check for these side effects. Normal cholesterol levels are important to good heart health. Healthcare providers may stop XELJANZ/XELJANZ XR treatment because of changes in blood cell counts or liver test results.
• Use of XELJANZ/XELJANZ XR in patients with severe hepatic impairment is not recommended.
• Patients should tell their healthcare providers if they plan to become pregnant or are pregnant.

"Forward-Looking Information and Factors That May Affect Future Results"

NEW YORK--(BUSINESS WIRE)--Pfizer Inc. announced today that the United States Food and Drug Administration (FDA) has accepted for review the supplemental New Drug Application (sNDA) for XELJANZ® (tofacitinib citrate) 5 mg twice daily (BID) for the treatment of adult patients with active psoriatic arthritis (PsA). A separate sNDA was also accepted for XELJANZ XR® (tofacitinib citrate) extended release 11 mg once daily use in PsA. The sNDA submission is based on data from the Phase 3 Oral Psoriatic Arthritis TriaLs (OPAL) clinical development program, which consisted of two pivotal trials and a long-term extension study, evaluating the safety and efficacy of XELJANZ in patients with active PsA who had failed prior PsA treatments. The FDA has provided an anticipated Prescription Drug User Fee Act (PDUFA) action date in December 2017 for the sNDAs.

“Psoriatic arthritis is a complex disease involving joint inflammation and damage, psoriasis, and musculoskeletal inflammation, which may limit physical functioning for people living with the disease. Despite advances in the treatment of psoriatic arthritis in recent years, many people are still living with active disease and are in need of additional therapeutic options,” said Michael Corbo, Chief Development Officer, Inflammation & Immunology, Global Product Development. “We believe that XELJANZ has the potential to provide patients with psoriatic arthritis and their physicians a new treatment option that also offers oral administration. If approved, XELJANZ or once-daily XELJANZ XR would be the first and only Janus kinase inhibitor for the treatment of this chronic inflammatory disease.”

Two pivotal Phase 3 studies were included in the submission package. OPAL Broaden was conducted in conventional synthetic disease-modifying antirheumatic drug (csDMARD) inadequate response (IR) and tumor necrosis factor inhibitor (TNFi)-naïve patient populations. The study included an active control arm of adalimumab. However, the study was not designed for non-inferiority or superiority comparisons between adalimumab and XELJANZ. OPAL Beyond was conducted in TNFi-IR patients and was the first PsA study focused exclusively in this population. Both studies met their primary efficacy endpoints showing a statistically significant improvement with XELJANZ 5 mg and 10 mg BID compared to treatment with placebo at three months as measured by American College of Rheumatology 20 (ACR20) response and change from baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) score. In both studies adverse events were more frequent with XELJANZ 5 mg and 10 mg BID versus placebo. Overall safety findings were consistent with those observed in the broader rheumatology clinical development program for XELJANZ. Interim results from OPAL Balance, the long-term extension study of XELJANZ in patients with active PsA, were also included in the submission package.

About Psoriatic Arthritis

Psoriatic Arthritis (PsA) is a chronic inflammatory multisystem disease. PsA can cause joint pain and stiffness, skin and nail psoriasis, swollen toes and fingers, persistent painful tendonitis, and irreversible joint damage. There are an estimated three million people in the U.S. and Europe combined with active PsA. Real world disease prevalence may be even higher because it is often misdiagnosed or goes undiagnosed altogether.

About XELJANZ (tofacitinib citrate) and XELJANZ XR (tofacitinib citrate) extended-release

XELJANZ®/XELJANZ XR® (tofacitinib citrate) is a prescription medicine called a Janus kinase (JAK) inhibitor. XELJANZ is not currently approved for the treatment of PsA.

As the developer of XELJANZ/XELJANZ XR, Pfizer is a leader in JAK innovation. The XELJANZ RA development program includes more than eight years of safety data from the long-term extension studies representing over 21,100 patient-years of drug exposure to date.

XELJANZ is approved in more than 80 countries around the world for the treatment of moderately to severely active rheumatoid arthritis (RA). In the United States, Argentina, and Macau, XELJANZ XR is the first once-daily oral JAK inhibitor approved for the treatment of moderately to severely active RA.

Pfizer is committed to advancing the science of JAK inhibition and enhancing understanding of XELJANZ through robust clinical development programs in the treatment of immune-mediated inflammatory conditions.

"This important update to the IBRANCE label underscores the strength of the data we continue to generate for IBRANCE. We are proud of the impact this innovative medicine continues to have on patients’ lives."

NEW YORK--(BUSINESS WIRE)--Pfizer Inc. (NYSE:PFE) today announced that the U.S. Food and Drug Administration (FDA) has approved a supplemental New Drug Application (sNDA) for its first-in-class cyclin dependent kinase 4/6 (CDK 4/6) inhibitor, IBRANCE® (palbociclib), based on the results from the confirmatory Phase 3 trial PALOMA-2. The FDA action converts the accelerated approval of IBRANCE to regular approval and broadens the range of anti-hormonal therapy that may be administered with IBRANCE. IBRANCE now is indicated in combination with an aromatase inhibitor, expanding on its earlier indication in combination with letrozole, as initial endocrine based therapy in postmenopausal women with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced or metastatic breast cancer.

IBRANCE is the first CDK 4/6 inhibitor approved by the FDA. IBRANCE was granted accelerated approval in combination with letrozole in February 2015 and regular approval in February 2016 for a second indication: the treatment of HR+, HER2- advanced or metastatic breast cancer in combination with fulvestrant in women with disease progression following endocrine therapy. Today, IBRANCE plus letrozole is the most prescribed FDA-approved oral combination treatment for HR+, HER2- metastatic breast cancer.

“In the two years since its initial approval, IBRANCE has been prescribed to more than 50,000 patients by more than 9,800 physicians in the U.S.,” said Liz Barrett, global president and general manager, Pfizer Oncology. “This important update to the IBRANCE label underscores the strength of the data we continue to generate for IBRANCE. We are proud of the impact this innovative medicine continues to have on patients’ lives.”

The updated label is based on data including results from the Phase 3 PALOMA-2 trial, which evaluated IBRANCE as first-line therapy in combination with letrozole for postmenopausal women with estrogen receptor-positive (ER+), HER2- metastatic breast cancer. These data were published in the November 17, 2016 issue of The New England Journal of Medicine. PALOMA-2 demonstrated that the combination of IBRANCE and letrozole significantly extended progression-free survival (PFS), or the amount of time before tumor growth, compared with letrozole plus placebo. The median PFS of the IBRANCE and letrozole combination exceeded two years – making it the first treatment for this population of women to do so in a Phase 3 study. The median PFS for women treated with IBRANCE plus letrozole exceeded the median PFS for placebo plus letrozole by more than 10 months (24.8 months [95% CI, 22.1, not estimable] vs. 14.5 months [95% CI, 12.9, 17.1] for women treated with letrozole plus placebo (HR=0.58 [95% CI, 0.46, 0.72], p<0.0001)), and represented a 42% reduction in the risk of disease progression.

The warnings and precautions of IBRANCE include neutropenia and embryo-fetal toxicity. Adverse reactions in PALOMA-2 were generally consistent with the known adverse reaction profile for IBRANCE and no major unexpected safety findings were observed. The most common grade 3/4 adverse reactions with IBRANCE plus letrozole versus placebo plus letrozole were neutropenia (66% vs 2%), leukopenia (25% vs 0%), infections (7% vs 3%) and anemia (5% vs 2%). Febrile neutropenia was reported in 2.5% of patients in the IBRANCE plus letrozole group and none of the patients in the placebo plus letrozole group.

Palbociclib (IBRANCE) is the only treatment for HR+, HER2- metastatic breast cancer with two category 1 recommendations from the National Comprehensive Care Network (NCCN). On March 13, the NCCN updated their recommendation for palbociclib plus letrozole as a first-line treatment for postmenopausal women with HR+, HER2- metastatic breast cancer to a category 1 recommendation.1 In addition, palbociclib plus fulvestrant is recommended (category 1) for postmenopausal women with HR+, HER2- metastatic breast cancer who have progressed on endocrine therapy or premenopausal women receiving a luteinizing hormone-releasing hormone (LHRH) agonist.1

The full prescribing information for IBRANCE can be found here.

IMPORTANT IBRANCE ® (palbociclib) SAFETY INFORMATION FROM THE U.S. PRESCRIBING INFORMATION

Neutropenia was the most frequently reported adverse reaction in PALOMA-2 (80%) and PALOMA-3 (83%). In PALOMA-2, Grade 3 (56%) or 4 (10%) decreased neutrophil counts were reported in patients receiving IBRANCE plus letrozole. In PALOMA-3, Grade 3 (55%) or Grade 4 (11%) decreased neutrophil counts were reported in patients receiving IBRANCE plus fulvestrant. Febrile neutropenia has been reported in 1.8% of patients exposed to IBRANCE across PALOMA-2 and PALOMA-3. One death due to neutropenic sepsis was observed in PALOMA-3. Inform patients to promptly report any fever.

Monitor complete blood count prior to starting IBRANCE, at the beginning of each cycle, on Day 15 of first 2 cycles and as clinically indicated. Dose interruption, dose reduction, or delay in starting treatment cycles is recommended for patients who develop Grade 3 or 4 neutropenia.

Based on the mechanism of action, IBRANCE can cause fetal harm. Advise females of reproductive potential to use effective contraception during IBRANCE treatment and for at least 3 weeks after the last dose. IBRANCE may impair fertility in males and has the potential to cause genotoxicity. Advise male patients with female partners of reproductive potential to use effective contraception during IBRANCE treatment and for 3 months after the last dose. Advise females to inform their healthcare provider of a known or suspected pregnancy. Advise women not to breastfeed during IBRANCE treatment and for 3 weeks after the last dose because of the potential for serious adverse reactions in nursing infants.

The most common adverse reactions (≥10%) of any grade reported in PALOMA-2 for IBRANCE plus letrozole vs placebo plus letrozole were neutropenia (80% vs 6%), infections (60% vs 42%), leukopenia (39% vs 2%), fatigue (37% vs 28%), nausea (35% vs 26%), alopecia (33% vs 16%), stomatitis (30% vs 14%), diarrhea (26% vs 19%), anemia (24% vs 9%), rash (18% vs 12%), asthenia (17% vs 12%), thrombocytopenia (16% vs 1%), vomiting (16% vs 17%), decreased appetite (15% vs 9%), dry skin (12% vs 6%), pyrexia (12% vs 9%), and dysgeusia (10% vs 5%).

The most frequently reported Grade ≥3 adverse reactions (≥5%) in PALOMA-2 for IBRANCE plus letrozole vs placebo plus letrozole were neutropenia (66% vs 2%), leukopenia (25% vs 0%), infections (7% vs 3%), and anemia (5% vs 2%).

Lab abnormalities of any grade occurring in PALOMA-2 for IBRANCE plus letrozole vs placebo plus letrozole were decreased WBC (97% vs 25%), decreased neutrophils (95% vs 20%), anemia (78% vs 42%), decreased platelets (63% vs 14%), increased aspartate aminotransferase (52% vs 34%), and increased alanine aminotransferase (43% vs 30%).

The most common adverse reactions (≥10%) of any grade reported in PALOMA-3 for IBRANCE plus fulvestrant vs placebo plus fulvestrant were neutropenia (83% vs 4%), leukopenia (53% vs 5%), infections (47% vs 31%), fatigue (41% vs 29%), nausea (34% vs 28%), anemia (30% vs 13%), stomatitis (28% vs 13%), diarrhea (24% vs 19%), thrombocytopenia (23% vs 0%), vomiting (19% vs 15%), alopecia (18% vs 6%), rash (17% vs 6%), decreased appetite (16% vs 8%), and pyrexia (13% vs 5%).

The most frequently reported Grade ≥3 adverse reactions (≥5%) in PALOMA-3 for IBRANCE plus fulvestrant vs placebo plus fulvestrant were neutropenia (66% vs 1%) and leukopenia (31% vs 2%).

Lab abnormalities of any grade occurring in PALOMA-3 for IBRANCE plus fulvestrant vs placebo plus fulvestrant were decreased WBC (99% vs 26%), decreased neutrophils (96% vs 14%), anemia (78% vs 40%), decreased platelets (62% vs 10%), increased aspartate aminotransferase (43% vs 48%), and increased alanine aminotransferase (36% vs 34%).

Avoid concurrent use of strong CYP3A inhibitors. If patients must be administered a strong CYP3A inhibitor, reduce the IBRANCE dose to 75 mg/day. If the strong inhibitor is discontinued, increase the IBRANCE dose (after 3-5 half-lives of the inhibitor) to the dose used prior to the initiation of the strong CYP3A inhibitor. Grapefruit or grapefruit juice may increase plasma concentrations of IBRANCE and should be avoided. Avoid concomitant use of strong CYP3A inducers. The dose of sensitive CYP3A substrates with a narrow therapeutic index may need to be reduced as IBRANCE may increase their exposure.

IBRANCE has not been studied in patients with moderate to severe hepatic impairment or in patients with severe renal impairment (CrCl <30 mL/min).
