Celator(R) Pharmaceuticals Announces Completion of Its Public Offering and the Exercise in Full of Option to Purchase Additional Units of Common Stock and Warrants to Purchase Common Stock

EWING, N.J., Oct. 28, 2014 (GLOBE NEWSWIRE) -- Celator Pharmaceuticals, Inc. (Nasdaq:CPXX), a biopharmaceutical company that is transforming the science of combination therapy and developing products to improve patient outcomes in cancer, today announced the closing of an underwritten public offering of 7,602,823 shares of common stock and warrants to purchase up to 760,282 shares of its common stock, including the exercise in full of the underwriters' over-allotment option to purchase up to an additional 991,673 units. The shares of common stock and warrants were offered in units consisting of one share of common stock and a warrant to purchase 0.10 of a share of common stock at a price of $1.95 per unit. The shares of common stock and the warrants are immediately separable and were issued separately. The warrants have an exercise price of $3.58 per whole share and have a term of five years. The net proceeds to Celator, after underwriting discounts and commissions and estimated offering expenses, were approximately $13.5 million.

Based on current projections, Celator believes it now has sufficient capital to fund its activities into the second half of 2016.

Celator intends to use the net proceeds from the offering for general corporate purposes including the advancement of the Celator's lead product candidate, CPX-351 (cytarabine:daunorubicin) Liposome for Injection, currently in a Phase 3 clinical study in patients with high risk (secondary) acute myeloid leukemia (AML); ongoing research with drug combinations involving molecularly targeted therapies using its proprietary technology platforms; manufacturing expenses; and general and administrative expenses.

Celator announced yesterday that it achieved the target enrollment, of 300 patients, in its Phase 3 study of CPX-351. This Phase 3 study is a multicenter, randomized, open-label study testing CPX-351 versus the current standard of care, conventional cytarabine and daunorubicin therapy (7+3) in patients with untreated high-risk (secondary) AML.

In addition, Celator expects the following milestones related to its Phase 3 clinical study:

Q4 2014 – Data and Safety and Monitoring Board pre-planned analysis of the first 225 randomized patients with a minimum of 60 days follow-up

Q2 2015 – Analysis of the induction response rate (CR+CRi), a secondary endpoint of the study

Q1 2016 – Analysis of overall survival, the primary endpoint of the study

Celator expects to present information on CPX-351 at the upcoming American Society of Hematology (ASH) conference in December.

About CPX-351

CPX-351 (cytarabine:daunorubicin) Liposome for Injection represents a new approach to developing combinations of drugs in which drug molar ratios with synergistic anti-tumor activity are encapsulated in a drug delivery vehicle in order to maintain the desired ratio following administration. CPX-351 has been granted orphan drug status by the U.S. Food & Drug Administration (FDA) and the European Commission (EC) for the treatment of AML. Celator has conducted two randomized, controlled, Phase 2 studies with CPX-351. The first study was conducted in newly diagnosed elderly AML patients and the second study was conducted in patients with AML in first relapse. In both Phase 2 studies, treatment with CPX-351 resulted in significant improvements in response rates, 60-day mortality, and overall survival in the highest risk patients. The Leukemia & Lymphoma Society® has partnered with Celator in the development of CPX-351 starting in Phase 2 and continuing in Phase 3.
