Item 8.01   Other Information

On May 14, 2020, the Company issued a press release announcing that on May 14, 2020 the Abstract titled “Tumor antigen expression and survival of patients with previously treated advanced non-small cell lung cancer (NSCLC) receiving viagenpumatucel-L (HS-110) plus nivolumab” which had been submitted by the Company to ASCO in connection with its 2020 Annual Meeting was published by ASCO.

The data presented in the Abstract was obtained from the Company’s ongoing Phase 2 trial in combination with Bristol-Myers Squibb’s (BMS) Opdivo® (nivolumab) for multiple treatment settings in advanced NSCLC.

The data presented included median overall survival (OS), which was 28.7 months with a median follow up of 15.7 months. This study is ongoing and 21 of the 47 patients enrolled (45%) were still alive as of this data-cut.

Exploratory biomarker analysis on cancer testis antigens (CTAs) was performed using patients’ tumor tissue at baseline. In this evaluation, improved overall survival (OS) was observed in patients whose tumors have 8 or more overlapping CTAs with the 39 CTAs overexpressed by HS-110. In addition, overexpression of zinc finger protein 492 (ZNF492) was associated with greater OS. ZNF492 is a transcription factor that is expressed in multiple cancers.

The information in the press release shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange  Act of 1934, as amended, or otherwise subject to the liabilities of that section or Sections 11 and 12(a)(2) of the Securities Act of 1933, as amended.
