TapImmune Inc. (NASDAQ: TPIV), a leading clinical-stage immuno-oncology company with ongoing clinical trials in ovarian and breast cancer, today provided its business update for the third quarter 2017. A public conference call and live audio webcast is scheduled for today at 4:30 p.m. ET.

"TapImmune continued to advance its clinical and preclinical programs in the third quarter, which I believe positions us very well to achieve a number of important milestones in 2017 and beyond," said Peter Hoang, President and CEO of TapImmune. "I believe TapImmune is well positioned to advance immuno-oncology with its broadly effective cancer vaccine candidates and proprietary technologies in the indications and treatment settings we are targeting.  Having joined the company in late September, I was drawn to TapImmune because I see an opportunity to lead our industry, in translating the promise of cancer immunotherapy into potentially life-changing therapeutic outcomes.

"As we continue to advance our deep clinical pipeline, I am determined to drive TapImmune to its full potential. Our primary objective is to continue executing on our active Phase 2 trials as efficiently as possible.  We and our clinical partners also expect to launch additional clinical studies for each of our novel cancer vaccine candidates in order to further highlight their potential and generate even more value for the company. I believe that driving clinical execution should lead to several significant catalysts for the company and its shareholders over the coming quarters and years. I expect to drive efficiencies from an operational, regulatory and commercial standpoint, so that we achieve every milestone we set for the company.  In parallel, my goal is to drive enhanced appreciation and support for TapImmune by the investor community.  Finally, I intend to pursue opportunities to bolster our pipeline through strategic corporate and business development initiatives, in an effort to further expand the market opportunity for TapImmune."

Current Clinical Studies:

TPIV200: Lead T-cell vaccine targeting folate receptor alpha

• Multi-center Phase 2 dosing study in triple-negative breast cancer
  The randomized study is designed to determine the optimal vaccine dose and regimen that may maximize the anti-tumor immune response in maintenance-phase patients, who have completed standard surgery and chemotherapy/radiation. TapImmune reached its enrollment target ahead of schedule, and currently expects to report interim immune response data in the first half of 2018.
• FDA Fast Tracked Phase 2 maintenance therapy study in platinum-sensitive ovarian cancer
  TapImmune is currently enrolling women who have completed initial therapy with a platinum regimen and are in first remission. Enrollment remains on track with projections and the company plans to conduct a blinded interim safety and futility analysis once the data from the first half of enrollment is achieved and responses mature, which is currently expected in early 2019.  This program benefits from FDA Fast Track and Orphan Drug designation.
• Memorial Sloan Kettering-sponsored Phase 2 combination study with AstraZeneca's durvalumab in platinum-resistant ovarian cancer
  Data from the first 27 patients enrolled in the study are currently being analyzed by the study's clinical investigators at MSKCC.  TapImmune anticipates reporting the results based on these 27 patients in the first half of 2018. If the safety profile remains favorable and there are sufficient signs of tumor response, patient enrollment may resume and the study can be completed as designed.

Planned Clinical Studies:

TPIV200:

• Mayo Clinic is expected to commence dosing in a Phase 2 study designed to evaluate the efficacy of TPIV200 in prolonging disease-free survival in women with advanced triple-negative breast cancer. This 280-patient study is planned to commence dosing in the fourth quarter 2017, and is completely funded by a $13.3 million grant from the U.S. Department of Defense.

TPIV100/110 T-cell vaccine targeting HER2/neu:

• TapImmune plans to complete FDA filings required to initiate a Phase 1b/2a clinical study with TPIV110, its five-peptide vaccine candidate for treating women with HER2/neu+ breast cancer.
• Mayo Clinic is expected to initiate a Phase 1b/2a study of TPIV100 in women with an early form of breast cancer called ductal carcinoma in situ (DCIS).  This study is also fully funded by a grant from the U.S. Dept. of Defense. If successful, TapImmune's HER2/neu-targeted vaccine may complement standard surgery and chemotherapy.
