Targazyme Inc. Receives Orphan Drug Designation to TZ101 for Use With Regulatory T Cells to Prevent & Reduce the Severity of Graft Versus Host Disease in Patients Eligible for Hematologic Stem Cell Transplantation

Orphan Designation Provides 7-Year Post Approval Marketing Exclusivity, Tax Credits and Elimination of FDA Prescription Drug User Fees

SAN DIEGO, CA--(Marketwired - February 10, 2015) - Targazyme Inc., a clinical-stage biopharmaceutical company developing enzyme technologies and products to improve efficacy outcomes for stem cell transplantation, immunotherapy, gene therapy and regenerative medicine, announced today that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug designation to TZ101 to prevent and reduce the severity and incidence of graft vs. host disease (GVHD) in patients eligible for hematologic stem cell transplant.

GVHD is a serious, life-threating complication of stem cell transplantation. Orphan drug status confirms the importance of Targazyme's novel treatment approach to prevent and reduce the incidence and severity of GVHD in patients with blood cancers where stem cell transplant is prescribed. TZ101 could potentially transform hematopoietic stem cell transplantation by reducing patient morbidity and mortality from GVHD, which occurs in a large percentage of these patients and is very difficult to manage clinically.

"Our work with TZ101 demonstrates impressive increases in the persistence and activity of regulatory T cells in preclinical models of GVHD," said Dr. Elizabeth J. Shpall, Deputy Chair of the Department of Stem Cell Transplantation and Cellular Therapy at The University of Texas MD Anderson Cancer Center. "We are looking forward to beginning clinical trials on this promising modality for preventing GVHD in our patients undergoing stem cell transplantation."

Orphan Drug Designation by FDA confers financial benefits and incentives, such as potential Orphan Drug grant funding to defray the cost of clinical testing, tax credits for the cost of clinical research, a 7 year period of exclusive marketing after Approval and a Waiver of Prescription Drug User Fee Act (PDUFA) filing fees which are now greater than $2 million.

"The granting of Orphan Drug status for TZ101 for prevention of GVHD in stem cell transplant patients, as well as our previous Orphan Drug designation of TZ101 for cord blood transplantation, provides additional validation of our innovative platform technologies," said Lynnet Koh, Chairman & Chief Executive Officer of Targazyme. "TZ101 and our second product, TZ102 are enabling technologies for improving efficacy outcomes for multiple cell-based therapeutic approaches used to prevent and treat a variety of different diseases for which there is a high unmet medical need. In addition to initiating our registration trial with TZ101 in hematopoietic stem cell transplantation, we plan to embark on our cancer immunotherapy trial later this year."
