Phase I Trial analyses shows safety and positive immune response data

SEATTLE, WA, USA I June 23, 2015 I TapImmune Inc. (TPIV) is pleased to report the completion of data analysis from patients treated in a Phase I clinical trial. In this Phase 1 trial conducted at the Mayo Clinic in Rochester, MN, women diagnosed with HER2+ breast cancer (Stages II-III) that had completed standard treatment (i.e. surgery, chemotherapy, and Herceptin™) at least 90 days prior to enrollment were declared disease free and were treated with a multi-peptide HER2/neu vaccine. Twenty-two subjects (age 33 to 69 years) were enrolled. Patients were injected six times over six months with the multi-peptide vaccine and were monitored for toxicity during each visit.  Twenty-one patients completed all 6 vaccination cycles.  Vaccine induced T-cell immunity was observed in 19 out of 20 evaluable patients.

Dr. Glynn Wilson, TapImmune’s CEO stated “We are excited by the Phase I results of our HER2/neu vaccine trial.  The potential to treat ~85% of breast cancer patients with this HER2/neu therapeutic approach is significant. The successful completion of this HER2/neu vaccine Phase I study and the robust immune responses detected provides TapImmune with a second Phase II clinical candidate and an expanded clinical pipeline for the treatment of breast and ovarian cancer. It also further validates the technology and the approach developed at Mayo Clinic by Professor Keith Knutson.”

The Company recently announced the results of a successful Phase I trial on a Folate Receptor Alpha Vaccine in ovarian and triple negative breast cancer and progression of this program into Phase II clinical trials. TapImmune has an exclusive option to license both the HER2/neu and Folate Receptor Alpha vaccine technologies from Mayo Clinic.
