To Our Valued Shareholders,

We achieved a number of important milestones in 2018 and 2019 that we believe reinforce the tremendous potential of our therapeutic pipeline.

First, we reported promising interim results from our ongoing Phase 2 study investigating HS-110 for advanced non-small cell lung cancer (NSCLC) in combination with Bristol-Myers Squibb's anti-PD-1 checkpoint inhibitor, nivolumab (Opdivo®). This data was quite encouraging, as the addition of HS-110 to nivolumab may restore anti-tumor activity in patients whose disease has progressed after checkpoint inhibitor therapy. The results have generated significant interest within the industry and we look forward to reporting additional data later this year.

We also expanded our Phase 2 trial to dose patients receiving front-line maintenance therapy for advanced NSCLC with HS-110 in combination with Merck's anti-PD1 checkpoint inhibitor, KEYTRUDA® (pembrolizumab).

Looking ahead, we anticipate filing two Phase 1 Investigational New Drug (IND) applications early this summer: HS-130, the first dual-acting immunotherapy designed to deliver local T-cell activation and co-stimulation; and PTX-35, our first-in-class T cell costimulator antibody.

We ended 2018 with approximately $28 million of cash, cash equivalents and short-term investments. As a result, we believe we are well funded beyond completion of enrollment in our Phase 2 HS-110 trial and our Q4 data readout. We expect to receive an additional $6.9 million in Cancer Prevention Research Institute of Texas (CPRIT) grant funds after filing our IND for PTX-35. We have been efficient in our use of funds, which has allowed us to operate under budget, further extending our runway on primarily clinical development programs.

We believe 2019 has the potential to be a transformative year for Heat with a number of key upcoming milestones. I’d like to personally thank you for your continued support, and encourage you to vote your shares.

Sincerely,

[HTBX_14A004.GIF]
