Heat Biologics, Inc. (NASDAQ:HTBX) Files An 8-K Other Events

Item8.01. Other Events.

On March 21, 2017, Heat Biologics, Inc. (the Company) issued a
press release announcing the latest results of its ongoing Phase
2 clinical trial of HS-110 in combination with Bristol-Myers
Squibbs anti-PD-1 checkpoint inhibitor, nivolumab (Opdivo), for
the treatment of non-small cell lung cancer (NSCLC). Fifteen
patients have completed the HS-110/nivolumab combination
treatment to-date and 12 of these 15 patients were evaluable for
ELISPOT analysis. Researchers reported a strong correlation
between T cell activation, tumor reductions and increased overall
survival in these 12 patients. These data reinforce preliminary
results seen in the first eight patients as reported last
December at the International Association for the Study of Lung
Cancer Annual Meeting.

Key findings include:

Immune responses to HS-110 were observed in all 5 patients that
exhibited tumor reductions.

No tumor reductions were observed in patients that did not mount
an immune response to HS-110.

The timing of immune responses to HS-110 corresponded to the
timing of observed clinical responses, and those responses appear
to be sustained.

To-date, 5 patients have been enrolled in the low tumor
infiltrating lymphocytes (TIL) cohort (patients with cold
tumors). Three of these 5 patients (60%) have experienced
significant tumor reduction, which is higher than the 10%
response rate of low TIL patients reported for existing data on
nivolumab alone.

^{Researchers also reported that the safety profile continues
to be favorable in the HS-110/nivolumab combination, with no
evidence of additional toxicities seen as compared to existing
data on nivolumab alone.}

^{A copy of the press release is attached as Exhibit 99.1 to
this Current Report on Form 8-K and is incorporated herein by
reference.}
