Oasmia Pharmaceutical’s Paclical is bioequivalent of Celgene’s Abraxane in treatment of women with metastatic breast cancer

Oasmia Pharmaceutical AB, a developer of a new generation of drugs within human and veterinary oncology, confirmed today the previously published findings from a head-to-head comparison study of its lead human cancer product Paclical and Celgene’s Abraxane, demonstrated superimposable paclitaxel PK profiles. The study was conducted in women with metastatic breast cancer.

“The present cross-over study of Paclical and Abraxane demonstrating virtually identical plasma levels of total and unbound drugs for the two formulations,” stated Olof Borgå, PhD, pharmacokinetic expert. “Statistical analysis demonstrated the two formulations to be bioequivalent with regard to drug concentrations. The bioequivalence demonstrated for unbound paclitaxel is of particular importance, since it is this concentration that is related to clinical effects. Also, the ratio between unbound and total drug showed bioequivalence.”

Oasmia believes that results from this study strengthen its position for rapid growth among competitors within the oncology sector, including Celgene Corporation and Sorrento Therapeutics, Inc. In 2014, Abraxane generated total net sales of $947 million, a 28 percent increase from the prior year. Further, Sorrento Therapeutics expanded its Cynviloq strategy into multiple cancer indications, potentially receiving over $1 billion compensation for rights.

“We are pleased that the final study data reflects the optimism many in the pharmaceutical industry have displayed regarding Paclical’s potential and its role as a key branded player in the oncology sector”, said Julian Aleksov, Executive Chairman of Oasima Pharmaceutical AB. “Abraxane is the current taxane market leader in the United States, and we have now clearly demonstrated that Paclical is at least an equal but with a more cost effective nanoparticle technology. We believe the upside for Paclical within this dynamic market place positions Oasmia for significant growth worldwide.”

About the Head-to-Head Comparison Study of Paclical and Abraxane

The cross-over, 2 cycle study was designed to compare the PK properties in 28 patients with metastatic breast cancer. Patients were randomized to receive a sequence of either Paclical->Abraxane or Abraxane->Paclical both as one hour infusion at 260 mg/m2, respectively.

There were no reported serious adverse events in the study. There were eleven grade 3 adverse events reported for Paclical and ten for Abraxane, with the most common event being neutropenia for both drugs.
