“Pfizer Oncology is committed to applying discoveries from cancer biology and genetics to the development of new drugs in a focused and rational way. This approach is being used to study crizotinib (PF-02341066), an ALK inhibitor, in lung cancer patients carrying the ALK fusion gene, and bosutinib, a dual Src and Bcr-Abl kinase inhibitor, in patients with chronic myelogenous leukemia who have progressed despite standard-dose imatinib,” said Dr. Mace Rothenberg, senior vice president of clinical development and medical affairs for Pfizer’s Oncology Business Unit. “We’re also working to apply this personalized approach to better understand how already approved agents, such as Sutent®, may work better in certain patient populations within approved indications.”
Advancing Research and Understanding in NSCLC
Pfizer Oncology has multiple compounds in development to treat the various forms of non-small cell lung cancer (NSCLC).
At ASCO, Pfizer will present updated data from an expansion cohort of a Phase 1/2 study evaluating crizotinib (PF-02341066) in patients with NSCLC carrying the ALK (anaplastic lymphoma kinase) fusion gene.(1) Alteration of the ALK gene is thought to be a key driver of lung tumorigenesis in a subset of NSCLC patients.(2),(3) Worldwide, it is estimated that approximately 45,000 newly diagnosed NSCLC patients per year are ALK positive.(4) These data will be featured in the ASCO Plenary Session on Sunday, June 6 (Abstract #3).
Crizotinib (PF02341066), a first-in-class, oral ALK inhibitor,(5) is currently being evaluated in an open-label randomized Phase 3 trial, known as PROFILE 1007, which compares crizotinib (PF-02341066) with standard of care chemotherapy in the treatment of ALK-positive recurrent NSCLC.(6) Crizotinib is also being studied in a Phase 2 trial, known as PROFILE 1005, in similar patients who have received more than one line of prior chemotherapy. Pfizer has partnered with Abbott Molecular to develop a diagnostic to screen patients with NSCLC for the presence of alterations in the ALK gene.
PF-00299804 is an investigational, oral, pan-HER (pan-human epidermal growth factor receptor) inhibitor. It is an irreversible small molecule inhibitor of HER-1 (EGFR - epidermal growth factor receptor), -2 and -4 tyrosine kinase. Data from a global, randomized Phase 2 trial evaluating the anti-tumor activity and safety of PF-00299804 compared to erlotinib, in patients with NSCLC following progression on treatment with one or more chemotherapy regimens, will be presented in a poster discussion session (Abstract #LBA7523, June 7).(7) PF-00299804 is currently being evaluated in BR.26, a Phase 3 double-blind, placebo-controlled, randomized study in patients with stage IIIB/IV NSCLC who have received standard chemotherapy and EGFR inhibitor therapy. This trial is being led by the National Cancer Institute of Canada (NCIC) - Clinical Trial Group (Kingston, Ontario).
Pfizer will present results from a Phase 3 trial (A4021016) of figitumumab (CP-751,871), a selective fully human IgG2 monoclonal antibody against the insulin like growth factor 1 receptor (IGF-1R) pathway, in combination with paclitaxel and carboplatin versus paclitaxel and carboplatin in patients with NSCLC (Abstract #7500, June 5).(8) This study was discontinued in December 2009 following the recommendation of an independent Data Safety Monitoring Committee who found that the addition of figitumumab to paclitaxel plus carboplatin would be unlikely to meet the primary endpoint of overall survival compared to paclitaxel plus carboplatin alone. Pfizer is continuing to analyze the clinical and biomarker data from this and other trials to identify a potential subset of NSCLC patients in whom further evaluation of figitumumab is warranted.
Additional Research in Identifying Molecular Targets
Bosutinib is an investigational oral dual Src and Bcr-Abl kinase inhibitor.(9) It is believed that bosutinib may inhibit activated Bcr-Abl in chronic myeloid leukemia (CML) cells that allow the cells to grow, survive and reproduce.(10)
- Phase 2 study of safety and efficacy of bosutinib in patients with Philadelphia chromosome positive chronic phase CML who are resistant to imatinib and other tyrosine kinases (Abstract #6502, June 7)(11)
Bosutinib is currently being evaluated in an ongoing, randomized, open-label, Phase 3 trial which compares bosutinib with standard dose imatinib in patients with previously untreated, chronic phase, Philadelphia chromosome (Ph+) CML.
As part of Pfizer Oncology’s commitment to advancing the science of renal cell carcinoma (RCC), Pfizer has partnered with Genomic Health, Inc. a molecular diagnostic company, on the development of a genomic test to estimate the risk of recurrence following surgery for patients with Stage 1-3 clear cell RCC.
- Identification of prognostic genomic markers in patients with localized clear cell RCC (Abstract #4501, June 5)(12)
Ongoing Evaluation of Sutent (sunitinib malate)
Sutent has played a significant role in advancing treatment for patients with advanced RCC or gastrointestinal stromal tumor (GIST) after disease progression on or intolerance to imatinib mesylate and remains a standard of care in these indications. Pfizer is continuing to study the potential role of Sutent in the treatment of various solid tumors including advanced NSCLC,(13) advanced castration-resistant prostate cancer,(14) and as adjuvant therapy for RCC, in Phase 3 trials.(15)
- Phase 3 patient-reported outcomes study in patients with pancreatic neuroendocrine tumors (NET) receiving sunitinib (Abstract #4003, June 5) (16)
- Updated efficacy and safety results of the Phase 3 trial of sunitinib versus placebo for the treatment of pancreatic NET (Abstract #4000, June 5) (17)
Analyses of efficacy and safety data from two Phase 3 trials of sunitinib in metastatic/advanced breast cancer will be presented. Earlier this year Pfizer announced that these studies did not meet their primary endpoints.
- Sunitinib in combination with docetaxel (D) vs D alone for the first-line treatment of advanced breast cancer (ABC) (Abstract #LBA1010, June 8)(18)
- Phase 3 Study of Sunitinib plus Capecitabine in Previously Treated ABC (Abstract # LBA1011, June 8)(19)
Additional Data Presentations
Pfizer will also present data from its development program, including:
- Interim data for ACT III - Phase 2 trial of PF-04948568 (CDX-110) [an investigational immuno-oncology vaccine targeting the tumor specific EGFR mutant EGFRvIII] in combination with temozolomide in patients with glioblastoma (Abstract #2014, June 5)(20)
- Final report of a phase 1 clinical pharmacokinetic and pharmacodynamic study of PD-00562271 targeting focal adhesion kinase (FAK) in advanced solid tumors (Abstract #3028, June 6)(21)
- Pharmacodynamically guided dose selection of PF-00337210, a VEGFR2 tyrosine kinase inhibitor in a phase 1 study (Abstract #3033, June 6)(22)
- First-in-human dose-escalation safety and PK trial of a novel intravenous humanized monoclonal CovX body inhibiting angiopoietin (Abstract #2524, June 5)(23)
Data on the following compounds and investigational agents will also be presented: axitinib (RCC),(24) Torisel (RCC),(25) Camptosar® (colorectal cancer),(26) and tremelimumab (melanoma, pancreatic).(27),(28)

About Sutent® (sunitinib malate)
Sutent is an oral multi-kinase inhibitor approved for the treatment of GIST after disease progression on or intolerance to imatinib mesylate and advanced / metastatic RCC.
Sutent works by blocking multiple molecular targets implicated in the growth, proliferation and spread of cancer. Two important Sutent targets, vascular endothelial growth factor receptor (VEGFR) and platelet-derived growth factor receptor (PDGFR), are expressed by many types of solid tumors and are thought to play a crucial role in angiogenesis, the process by which tumors acquire blood vessels, oxygen and nutrients needed for growth. Sutent also inhibits other targets important to tumor growth, including KIT, FLT3 and RET.
Important Sutent® (sunitinib malate) Safety Information
Hepatic failure was observed in <1% of solid tumor patients treated with Sutent, sometimes with a fatal outcome. Monitor liver function tests and if symptoms of hepatic failure are present, patients should have Sutent discontinued.
Women of childbearing age who are (or become) pregnant during therapy should be informed of the potential for fetal harm while on Sutent.
Decreases in left ventricular ejection fraction (LVEF) to below the lower limit of normal (LLN) have been observed. Patients with concomitant cardiac conditions should be carefully monitored for clinical signs and symptoms of congestive heart failure.
Patients should be monitored for hypertension and treated as needed with standard antihypertensive therapy. Complete blood counts (CBCs) with platelet count and serum chemistries should be performed at the beginning of each treatment cycle for patients receiving treatment with Sutent.
The most common adverse reactions in GIST and RCC clinical trials were fatigue, asthenia, diarrhea, nausea, mucositis/stomatitis, vomiting, dyspepsia, abdominal pain, constipation, hypertension, rash, hand-foot syndrome, skin discoloration, altered taste, anorexia and bleeding.

About Torisel® (temsirolimus)
Torisel is the only intravenous mammalian target of rapamycin (mTOR) inhibitor approved for the treatment of advanced renal cell carcinoma (RCC) in the first-line setting.
Based on preclinical studies, Torisel inhibits the activity of mTOR, an intracellular protein implicated in multiple growth-related cellular functions including proliferation, growth and survival. The inhibition of mTOR also reduces levels of certain growth factors, such as vascular endothelial growth factor (VEGF), which are overexpressed in solid tumors like kidney cancer and are thought to play a crucial role in angiogenesis, the process by which tumors acquire blood vessels, nutrients and oxygen needed for growth.
Important Torisel® (temsirolimus) Safety Information
Hypersensitivity reactions manifested by symptoms, including, but not limited to anaphylaxis, dyspnea, flushing, and chest pain have been observed with Torisel. Serum glucose, serum cholesterol, and triglycerides should be tested before and during treatment with Torisel. The use of Torisel is likely to result in hyperglycemia and hyperlipemia. This may result in the need for an increase in the dose of, or initiation of, insulin and/or oral hypoglycemic agent therapy and/or lipid-lowering agents, respectively.
The use of Torisel may result in immunosuppression. Patients should be carefully observed for the occurrence of infections, including opportunistic infections. Cases of interstitial lung disease, some resulting in death, have occurred. Some patients were asymptomatic and others presented with symptoms. Some patients required discontinuation of Torisel and/or treatment with corticosteroids and/or antibiotics. Cases of fatal bowel perforation occurred with Torisel. These patients presented with fever, abdominal pain, metabolic acidosis, bloody stools, diarrhea, and/or acute abdomen. Cases of rapidly progressive and sometimes fatal acute renal failure not clearly related to disease progression occurred in patients who received Torisel.
Due to abnormal wound healing, use Torisel with caution in the perioperative period. Patients with central nervous system tumors (primary CNS tumor or metastases) and/or receiving anticoagulation therapy may be at an increased risk of developing intracerebral bleeding (including fatal outcomes) while receiving Torisel. Live vaccinations and close contact with those who received live vaccines should be avoided. Patients and their partners should be advised to avoid pregnancy throughout treatment and for 3 months after Torisel therapy has stopped.
The most common (incidence greater than or equal to 30 percent) adverse reactions observed with Torisel are: rash (47 percent), asthenia (51 percent), mucositis (41 percent), nausea (37 percent), edema (35 percent), and anorexia (32 percent). The most common laboratory abnormalities (incidence greater than or equal to 30 percent) are anemia (94 percent), hyperglycemia (89 percent), hyperlipemia (87 percent, hypertriglyceridemia (83 percent), elevated alkaline phosphatase (68 percent), elevated serum creatinine (57 percent), lymphopenia (53 percent), hypophosphatemia (49 percent), thrombocytopenia (40 percent), elevated AST (38 percent), and leukopenia (32 percent). Most common grades 3/4 adverse events included asthenia (11 percent), dyspnea (9 percent), hemoglobin decreased (20 percent), lymphocytes decreased (16 percent), glucose increased (16 percent), phosphorus decreased (18 percent), and triglycerides increased (44 percent).
Strong inducers of CYP3A4/5 (e.g., dexamethasone, rifampin) and strong inhibitors of CYP3A4 (e.g., ketoconazole, atazanavir) may decrease and increase concentrations of the major metabolite of TORISEL, respectively. If alternatives cannot be used, dose modifications of Torisel are recommended. St. John’s Wort may decrease Torisel plasma concentrations, and grapefruit juice may increase plasma concentrations of the major metabolite of Torisel, and therefore both should be avoided. The combination of Torisel and sunitinib resulted in dose-limiting toxicity (Grade 3/4 erythematous maculopapular rash, and gout/cellulitis requiring hospitalization).
Please see TORISEL full Prescribing Information at http://www.Torisel.com.
About Camptosar® (irinotecan HCI injection)
Camptosar is indicated as a component of 1st line therapy in combination with 5-FU/LV for the treatment of metastatic colorectal cancer. Camptosar is also indicated for patients with mCRC whose disease has recurred or progressed following initial FU-based therapy.
Important Camptosar® (irinotecan HCI injection) Safety Information
With Camptosar, both early and late forms of diarrhea can occur and may be life threatening. Late diarrhea should be managed promptly with loperamide and supportive care including antibiotics as needed. Camptosar can induce severe myelosuppression. Depending on the severity of neutropenia, dose delay, dose reduction, or use of a colony-stimulating factor should be considered.
Particular caution should be exercised in monitoring the effects of Camptosar in the elderly (>65), in patients who have previously received pelvic/abdominal irradiation, in patients with performance status of 2 or higher, and in patients known to be homozygous for the UGT1A1*28 allele. Rare cases of ileus, complicated colitis, or renal impairment have been observed. It is recommended that patients receive premedication with antiemetic agents. Prophylactic or therapeutic administration of atropine should be considered in patients experiences cholingeric symptoms. Provided intolerable toxicity does not develop, treatment with additional courses may be continued indefinitely as long as patients continue to experience clinical benefits. Thromboembolic events have been observed but the specific cause has not been determined. Camptosar should not be used in patients with severe bone marrow failure. Vaccination with a live vaccine should be avoided in patients receiving irinotecan due to the potential for serious fatal infections. In addition, patients with hereditary fructose intolerance should not be given Camptosar, as this product contains sorbitol.
