- Plans Interim Lung Cancer Phase 2 Readout in Q4 2018 and Final Readout in Q2 2019
- Expects to File IND and Enroll First Patient in ComPACT Trial in Q4 2018
- Anticipates Receipt of $6.9 Million in CPRIT Grant Funds in Q3 2018 to Support Filing of IND for PTX-35 in Q1 2019

DURHAM, NC / ACCESSWIRE / April 18, 2018 / Heat Biologics, Inc. (NASDAQ: HTBX), a biopharmaceutical company developing drugs designed to activate a patient's immune system against cancer, today provided guidance on upcoming clinical milestones for HS-110 in non-small cell lung cancer (NSCLC), its ComPACT™ platform, as well its Pelican subsidiary's co-stimulator antibody, PTX-35.

Anticipated Phase 2 NSCLC milestones include an interim data readout in Q4 2018 and a final Phase 2 data readout in Q2 2019, followed by a Phase 3-ready NSCLC program in Q3 2019. Expected PTX-35 milestones include receipt of $6.9 million in CPRIT grant funds to support the enrollment of the first patient in a Phase 1 clinical trial in Q1 2019 and an interim data readout in Q3 2019. Additionally, Heat plans on enrolling its first patient in its ComPACT trial in Q4 2018 and anticipates an interim data readout in Q2 2019.

Jeff Wolf, Heat's CEO, commented, "The next four quarters are shaping up to be very exciting, with events that we believe will be transformational for our company. Earlier this year we reported positive interim results from the Phase 2 study investigating HS-110 in combination with Bristol-Myers Squibb's anti-PD-1 checkpoint inhibitor, nivolumab (Opdivo®), in patients with advanced NSCLC. We observed some potentially very exciting data with this combination that points to the opportunity to use this combined therapy in a very underserved population of NSCLC patients."

"Given all the recent progress, I am pleased to announce these upcoming milestones for the next 4 quarters. Importantly, we believe each of these milestones will help drive shareholder value. At the same time, we are witnessing advancements in the immuno-oncology landscape that are resulting in a growing interest in our technology across the industry, and, hence, we strongly believe our assets will play an important role in the future of combination immunotherapies."

Anticipated milestones:

Q3 2018:

  • Receive $6.9M in CPRIT (Cancer Prevention Research Institute of Texas) grant funds

Q4 2018:

  • Interim Phase 2 NSCLC data readout
  • IND filing for first ComPACT trial
