Pfizer Announces $3 Million Grants Program to Further Clinical Research in Advanced Breast Cancer
Pfizer Inc. today announced the launch of a competitive, peer-reviewed grants program to support clinical research projects investigating IBRANCE® (palbociclib) in advanced breast cancer.
Pfizer Inc. today announced the launch of a competitive, peer-reviewed grants program to support clinical research projects investigating IBRANCE® (palbociclib) in advanced breast cancer. The multi-year program, which will award a total of up to $3 million in grants to investigators in the United States, is an extension of Pfizer’s Advancing Science through Pfizer Investigator Research Exchange (ASPIRE) initiative. It is the first ASPIRE program to focus on breast cancer research.
IBRANCE received accelerated approval by the U.S. Food and Drug Administration in February 2015 for use in combination with letrozole for the treatment of postmenopausal women with estrogen receptor-positive, human epidermal growth factor receptor 2-negative (ER+/HER2-) advanced breast cancer as initial endocrine-based therapy for their metastatic disease.
“We believe the ASPIRE Breast Cancer Research Awards will contribute important information to our body of knowledge about the role IBRANCE plays in the treatment and clinical management of advanced breast cancer, and will complement the robust clinical development program we have ongoing,” said Dr. Julia Perkins Smith, senior medical director, U.S. Breast Cancer Lead, Pfizer Oncology. “Through these awards, we also look forward to supporting the mission of the ASPIRE program to further academic research and nurture the career development of emerging investigators in a disease area of high unmet medical need.”
“This is an exciting opportunity to gain a better understanding of the efficacy and tolerability of CDK inhibition in ER+ breast cancer,” said Dr. Ruth O’Regan, head of hematology and oncology in the Department of Medicine at the University of Wisconsin School of Medicine and Public Health.
Grantees will be selected through a competitive application process overseen by an independent review panel of breast cancer experts.
The review panel encourages investigators (with a special interest for emerging researchers at Assistant Professor level or equivalent) to submit applications for innovative research in several areas. Highlights of the research of interest include:
- Improving the medical knowledge of palbociclib in the treatment of advanced breast cancer
- Optimizing clinical management during palbociclib treatment that addresses or improves patient compliance and convenience and/or patient reported outcomes

. The application submission period ends September 8, 2015, and successful awardees will be notified in October. Pfizer anticipates providing up to six awards to investigators in the United States.
IBRANCE is an oral inhibitor of cyclin-dependent kinases (CDKs) 4 and 6.
CDKs 4 and 6 are key regulators of the cell cycle that trigger cellular progression.
IBRANCE is indicated in the U.S. for use in combination with letrozole for the treatment of postmenopausal women with estrogen receptor-positive, human epidermal growth factor receptor 2-negative (ER+/HER2-) advanced breast cancer as initial endocrine-based therapy for their metastatic disease. The effectiveness of IBRANCE in these patients is based on a study that measured progression-free survival. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

Important IBRANCE (palbociclib) Safety Information
Neutropenia: Neutropenia is frequently reported with IBRANCE therapy. In the randomized phase II study, Grade 3 (57%) or 4 (5%) decreased neutrophil counts were reported in patients receiving IBRANCE plus letrozole. Febrile neutropenia can occur. Monitor complete blood count prior to starting IBRANCE and at the beginning of each cycle, as well as Day 14 of the first two cycles, and as clinically indicated. For patients who experience Grade 3 neutropenia, consider repeating the complete blood count monitoring 1 week later. Dose interruption, dose reduction, or delay in starting treatment cycles is recommended for patients who develop Grade 3 or 4 neutropenia.
Infections: Infections have been reported at a higher rate in patients treated with IBRANCE plus letrozole (55%) compared with letrozole alone (34%). Grade 3 or 4 infections occurred in 5% of patients treated with IBRANCE plus letrozole vs no patients treated with letrozole alone. Monitor patients for signs and symptoms of infection and treat as medically appropriate.
Pulmonary embolism (PE): PE has been reported at a higher rate in patients treated with IBRANCE plus letrozole (5%) compared with no cases in patients treated with letrozole alone. Monitor patients for signs and symptoms of PE and treat as medically appropriate.
Pregnancy and lactation: Based on the mechanism of action, IBRANCE can cause fetal harm. Advise females with reproductive potential to use effective contraception during therapy with IBRANCE and for at least 2 weeks after the last dose. Advise females to contact their healthcare provider if they become pregnant or if pregnancy is suspected during treatment with IBRANCE. Advise women not to breastfeed while on IBRANCE therapy because of the potential for serious adverse reactions in nursing infants from IBRANCE.
Additional hematologic abnormalities: Decreases in hemoglobin (83% vs 40%), leukocytes (95% vs 26%), lymphocytes (81% vs 35%), and platelets (61% vs 16%) occurred at a higher rate in patients treated with IBRANCE plus letrozole vs letrozole alone.
Adverse reactions: The most common all causality adverse reactions (≥10%) of any grade reported in patients treated with IBRANCE plus letrozole vs letrozole alone in the phase II study included neutropenia (75% vs 5%), leukopenia (43% vs 3%), fatigue (41% vs 23%), anemia (35% vs 7%), upper respiratory infection (31% vs 18%), nausea (25% vs 13%), stomatitis (25% vs 7%), alopecia (22% vs 3%), diarrhea (21% vs 10%), thrombocytopenia (17% vs 1%), decreased appetite (16% vs 7%), vomiting (15% vs 4%), asthenia (13% vs 4%), peripheral neuropathy (13% vs 5%), and epistaxis (11% vs 1%).
Grade 3/4 adverse reactions reported (≥10%) occurring at a higher incidence in the IBRANCE plus letrozole vs letrozole alone group include neutropenia (54% vs 1%) and leukopenia (19% vs 0%). The most frequently reported serious adverse events in patients receiving IBRANCE were pulmonary embolism (4%) and diarrhea (2%).
General dosing information: The recommended dose of IBRANCE is 125 mg taken orally once daily for 21 days followed by 7 days off treatment in 28-day cycles. IBRANCE should be taken with food and in combination with letrozole 2.5 mg once daily continuously. Patients should be encouraged to take their dose at approximately the same time each day.
Capsules should be swallowed whole. No capsule should be ingested if it is broken, cracked, or otherwise not intact. If a patient vomits or misses a dose, an additional dose should not be taken that day. The next prescribed dose should be taken at the usual time.
Management of some adverse reactions may require temporary dose interruption/delay and/or dose reduction, or permanent discontinuation. Dose modification of IBRANCE is recommended based on individual safety and tolerability.
Drug interactions: 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 and moderate CYP3A inducers. The dose of the sensitive CYP3A substrates with a narrow therapeutic index may need to be reduced as IBRANCE may increase their exposure.
Hepatic and renal impairment: IBRANCE has not been studied in patients with moderate to severe hepatic impairment or in patients with severe renal impairment (CrCl <30 mL/min).
