SOUTH SAN FRANCISCO, Calif., Aug. 13, 2012 (GLOBE NEWSWIRE) -- Talon Therapeutics, Inc., (OTCBB:TLON), today reported financial results for the three and six months ended June 30, 2012. "The FDA's decision to approve our NDA seeking accelerated approval of Marqibo (R) (vinCRIStine sulfate LIPOSOME injection) is a seminal event for Talon," stated Steven R. Deitcher, President, Chief Executive Officer and Board Member of Talon Therapeutics. "Our focus now turns to making Marqibo (R) available to patients in the United States. We are operating on parallel commercialization paths, including planning activities to launch Marqibo (R) ourselves, as well as consideration of strategic partnerships." Recent Corporate Highlights:
- FDA approves new drug application (NDA) seeking accelerated approval of Marqibo(R) for the treatment of adult patients with Philadelphia chromosome negative (Ph-) acute lymphoblastic leukemia (ALL) in second or greater relapse or whose disease has progressed following two or more anti-leukemia therapies.
- Enrollment and dosing of the first patient in the Phase 3 confirmatory study of Marqibo(R) in adults (60 years of age and older) with newly diagnosed Ph- ALL.
- Appointment of Thomas DeZao as Vice President of Commercial Operations and Planning and initiation of commercialization activities.
Total operating expenses for the three months ended June 30, 2012 were $3.7 million, compared with $4.8 million for the three months ended June 30, 2011. Research and development expenses were $2.2 million for the three months ended June 30, 2012, compared with $3.5 million for the corresponding period in the preceding year. The decrease of $1.3 million reflects a reduction in clinical and manufacturing activity following the submission of Talon's NDA for Marqibo (R), offset by a slight increase in personnel related expenses. General and administrative expenses were $1.5 million for the three months ended June 30, 2012, compared with $1.3 million for the corresponding period in the preceding year.As of June 30, 2012, the Company had cash and cash equivalents of $3.0 million. Cash used in operations was $3.8 million for the three months ended June 30, 2012. Six Months Ended June 30, 2012 Financial Results For the six months ended June 30, 2012, Talon reported a net loss of $91.3 million and deemed dividends attributable to preferred stock of $7.2 million, which when combined, resulted in a net loss applicable to common stockholders of $98.5 million, or $4.50 per share. This compares to a net loss of $16.5 million and deemed dividends of$1.9 million, which when combined, resulted in a net loss of $18.4 million, or $0.86 per share, for the six months ended June 30, 2011. The change in fair value of Talon's preferred stockholders' rights to purchase shares of preferred stock contributed to $80.2 million, or $3.67 per share, of the total net loss applicable to common stockholders for the six months ended June 30, 2012. The deemed dividends attributable to preferred stock contributed to $7.2 million, or $0.33 per share, of the total net loss applicable to common stockholders for the six months ended June 30, 2012.
Total operating expenses for the six months ended June 30, 2012 were $8.1 million, compared with $11.4 million for the six months ended June 30, 2011. Research and development expenses were $4.9 million for the six months ended June 30, 2012, compared with $8.7 million for the corresponding period in the preceding year. The decrease of $3.8 million reflects decreased activity following the submission of Talon's NDA for Marqibo (R) , offset by expenses related to the March 2012 Oncologic Drugs Advisory Committee (ODAC) meeting. General and administrative expenses were $3.2 million for the six months ended June 30, 2012, compared with $2.8 million for the corresponding period in the preceding year.Cash used in operations was $8.2 million for the six months ended June 30, 2012. About Marqibo(R) Marqibo is a novel, sphingomyelin/cholesterol liposome-encapsulated, formulation of vincristine sulfate. Vincristine, a microtubule inhibitor, is FDA-approved for ALL and Non-Hodgkin's Lymphoma (NHL) and is widely used in combination regimens for treatment for a variety of adult and pediatric hematologic and solid tumor malignancies. The Optisome(TM) nanoparticle encapsulation technology, utilized by Talon, has been shown to provide prolonged circulation of vincristine in the blood. Marqibo has received orphan drug designation for the treatment of ALL from the FDA and from the European Medicines Agency (EMA). Talon intends to submit a Marketing Authorization Application to the EMA in 2013. Please see important safety information below and the full prescribing information for Marqibo at www.marqibo.com. Indication and usage Marqibo is a liposomal vinca alkaloid indicated for the treatment of adult patients with Philadelphia chromosome-negative (Ph-) acute lymphoblastic leukemia (ALL) in second or greater relapse or whose disease has progresses following two or more anti-leukemia therapies. This indication is based on overall response rate. Clinical benefit such as improvement in overall survival has not been verified.
Important safety informationCONTRAINDICATIONS
- Marqibo is contraindicated in patients with demyelinating conditions including Charcot-Marie-Tooth syndrome
- Marqibo is contraindicated in patients with hypersensitivity to vincristine sulfate or any of the other components of Marqibo (vinCRIStine sulfate LIPOSOME injection
- Marqibo is contraindicated for intrathecal administration
- For Intravenous Use Only -- Fatal if Given by Other Routes
- Death has occurred with intrathecal use
- Marqibo (vinCRIStine sulfate LIPOSOME injection) has different dosage recommendations than vinCRIStine sulfate injection. Verify drug name and dose prior to preparation and administration to avoid overdosage.
Constipation and Bowel ObstructionIleus, bowel obstruction, and colonic pseudo-obstruction have occurred. Marqibo can cause constipation. Institute a prophylactic bowel regimen to mitigate potential constipation, bowel obstruction, and/or paralytic ileus, considering adequate dietary fiber intake, hydration, and routine use of stool softeners, such as docusate. Additional treatments, such as senna, bisacodyl, milk of magnesia, magnesium citrate, and lactulose may be considered. Fatigue Marqibo can cause severe fatigue. Marqibo dose delay, reduction, or discontinuation may be necessary. Hepatic Toxicity Fatal liver toxicity and elevated levels of aspartate aminotransferase have occurred. Elevated levels of aspartate aminotransferase of Grade >=3 occurred in 6-11% of patients in clinical trials. Monitor hepatic function tests. Reduce or interrupt Marqibo for hepatic toxicity. Embryofetal Toxicity Marqibo can cause fetal harm when administered to a pregnant woman. Vincristine sulfate liposome injection was teratogenic or caused embryo-fetal death in animals. Women of childbearing potential should avoid becoming pregnant while being treated with Marqibo. There are no adequate and well-controlled studies of Marqibo in pregnant women and there were no reports of pregnancy in any of the clinical studies in the Marqibo clinical development program. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus [see Use in Specific Populations]. Adverse Reactions The most common adverse reactions (>30%) were constipation (57%), nausea (52%), pyrexia (43%), fatigue (41%), peripheral neuropathy (39%), febrile neutropenia (38%), diarrhea (37%), anemia (34%), decreased appetite (33%), and insomnia (32%). The most commonly reported SAEs included febrile neutropenia (20.5%), pyrexia (13.3%), hypotension (7.2%), respiratory distress (6.0%), and cardiac arrest (6.0%). Twenty-eight percent of patients experienced adverse reactions leading to treatment discontinuation. The most common adverse reactions that caused treatment discontinuation were peripheral neuropathy (10%), leukemia-related (7%), and tumor lysis syndrome (2%).
Deaths occurred in 23% of patients in study 1. The non-leukemia related causes of deaths were brain infarct (1), intracerebral hemorrhage (2), liver failure (1), multi-system organ failure (2), pneumonia and septic shock (3), respiratory failure (4), pulmonary hemorrhage (1), and sudden cardiac death (1).Drug Interactions No formal drug interaction studies have been conducted with Marqibo. Marqibo is expected to interact with drugs known to interact with non-liposomal vincristine sulfate. Simultaneous oral or intravenous administration of phenytoin and antineoplastic chemotherapy combinations that included non-liposomal vincristine sulfate has been reported to reduce blood levels of phenytoin and to increase seizure activity. CYP3A Interactions Vincristine sulfate, the active agent in Marqibo, is a substrate for cytochrome P450 3A isozymes (CYP3A); therefore, the concomitant use of strong CYP3A inhibitors should be avoided (e.g., ketoconazole, itraconazole, voriconazole, posaconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin). Similarly, the concomitant use of strong CYP3A inducers should be avoided (e.g., dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, rifapentine, phenobarbital, St. John's Wort). P-glycoprotein Interactions Vincristine sulfate, the active agent in Marqibo, is also a substrate for P-glycoprotein (P-gp). The effect of concomitant use of potent P-gp inhibitors or inducers has not been investigated; it is likely that these agents will alter the pharmacokinetics or pharmacodynamics of Marqibo. Therefore the concomitant use of potent P-gp inhibitors or inducers should be avoided. Use in Specific Populations Pregnancy Pregnancy Category D [ see Warnings and Precautions] Based on its mechanism of action and findings from animal studies, Marqibo can cause fetal harm when administered to pregnant women. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. In an embryofetal developmental study, pregnant rats were administered vincristine sulfate liposome injection intravenously during the period of organogenesis at vincristine sulfate doses of 0.022 to 0.09 mg/kg/day. Drug-related adverse effects included fetal malformations (skeletal and visceral), decreases in fetal weights, increased numbers of early resorptions and post-implantation losses, and decreased maternal body weights Malformations were observed at doses >= 0.044 mg/kg/day in animals at systemic exposures approximately 20-40% of those reported in patients at the recommended dose.
Nursing MothersIt is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or discontinue the drug taking into account the importance of the drug to the mother. Pediatric Use The safety and effectiveness of Marqibo in pediatric patients have not been established. Geriatric Use Safety and effectiveness in elderly individuals have not been established. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Renal Impairment The influence of renal impairment on the safety, efficacy, and pharmacokinetics of Marqibo has not been evaluated. Hepatic Impairment Non-liposomal vincristine sulfate is excreted primarily by the liver. The influence of severe hepatic impairment on the safety and efficacy of Marqibo has not been evaluated. The pharmacokinetics of Marqibo was evaluated in patients with moderate hepatic dysfunction (Child-Pugh B) secondary to melanoma liver metastases. The dose-adjusted maximum plasma concentration (C max) and area under the concentration-time curve (AUC) of Marqibo in patients with moderate hepatic impairment was comparable to the C max and AUC of patients with ALL who had otherwise normal hepatic function.
