Protalix BioTherapeutics' Taliglucerase Alfa Phase III Results Published In Blood, The Journal Of The American Society Of Hematology

Stocks in this article: PLX

Statistically significant improvements were also observed for the secondary endpoints after nine months when compared to baseline for the 60 U/kg dose.  Patients demonstrated a mean increase in hemoglobin of 2.2 g/dL or 22.2 percent (p<0.0001), a mean decrease in liver volume of 11.1 percent (p<0.0001) and a mean elevation in platelet count of 41,494 ml or 72.1 percent (p=0.0031).  For patients in the 30 U/kg dose, statistically significant improvements after nine months compared with baselines were observed for hemoglobin level (increased 1.6 g/dL or 14.8 percent; p=0.0010) and liver size (decreased 10.48 percent; p=0.0041); a nominal elevation in platelet count was also seen (11,427 ml or 13.7 percent; p=0.0460).

The safety analysis for both treatment groups showed that taliglucerase alfa was well tolerated and no serious or severe adverse events were reported.  Two patients in the trial developed antibodies to taliglucerase alfa and no patients developed neutralizing antibodies.  In addition, two patients experienced hypersensitivity reactions to taliglucerase alfa.  No anti-taliglucerase antibodies were detected in these patients and both reactions were successfully treated in the physicians' office.

On November 30, 2009, Pfizer and Protalix BioTherapeutics, Inc. entered into an agreement to develop and commercialize taliglucerase alfa.  Pfizer remains fully dedicated to the Gaucher disease community and to its relationship with Protalix and has worked closely with Protalix providing technical, analytical and regulatory expertise.

Forward Looking Statements

To the extent that statements in this press release are not strictly historical, all such statements are forward-looking, and are made pursuant to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995.  The terms "anticipate," "believe," "estimate," "expect" and "intend" and other words or phrases of similar import are intended to identify forward-looking statements.  These forward-looking statements are subject to known and unknown risks and uncertainties that may cause actual future experience and results to differ materially from the statements made.  These statements are based on our current beliefs and expectations as to such future outcomes.  Drug discovery and development involve a high degree of risk.  Factors that might cause material differences include, among others: risks relating to the review process of the FDA, the European Medicines Agency (EMA), other foreign regulatory bodies and other governmental regulatory bodies, including the risk that regulatory authorities may find that the data from our clinical trials and other studies is insufficient for regulatory approval; risks relating to delays in the FDA's, the EMA's or other foreign regulatory authorities' approval of any applications we file or refusals to approve such filings, including the NDA we filed with the FDA for taliglucerase alfa for the treatment of Gaucher disease; applicable regulatory authorities may refuse to approve the marketing and sale of a drug product even after acceptance of an application we file for the drug product; risks relating to the completion of our clinical trials; and other factors described in our filings with the Securities and Exchange Commission.  Companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced or late-stage clinical trials, even after obtaining promising earlier trial results or in preliminary findings for such clinical trials.  Further, even if favorable testing data is generated from clinical trials of drug products, the FDA, EMA or any other foreign regulatory authority may not accept or approve an NDA filed by a pharmaceutical or biotechnology company for such drug product.  Failure to obtain approval from the FDA, EMA or any other foreign regulatory authority of any of our drug candidates in a timely manner, if at all, will severely undermine our business and results of operations by reducing our potential marketable products and our ability to generate corresponding product revenues.  The statements in this release are valid only as of the date hereof and we disclaim any obligation to update this information.
