A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

Item 8.01.  Other Events.

On February 9, 2021, the Company issued a press release announcing positive interim data from its ongoing fully enrolled Phase 2 trial of HS-110 in combination with Bristol-Myers Squibb’s (BMS) OPDIVO® (nivolumab) in advanced non-small cell lung cancer (NSCLC).

Substantial survival benefit was observed in a cohort of previously treated, checkpoint inhibitor naïve patients with advanced NSCLC (Cohort A, N = 47). A median progression free survival (PFS) of 1.8 months and a median overall survival (OS) of 24.6 months was observed with a median follow-up time of 19.4 months. The one-year survival rate of Cohort A is 61.7%. The median OS data was 12.2 months and the 1-year survival rate was 50.7% in previously treated, advanced NSCLC patients who received nivolumab as a single agent, according to published data of the BMS CheckMate 057 study.

For NSCLC patients who had previously been treated with a checkpoint inhibitor and whose disease had subsequently progressed (Cohort B, N = 68), a median PFS of 2.8 months and median OS of 11.9 months was observed with a median follow-up time of 11.9 months. Published data from other studies reported median OS of 6.8 to 9.0 months for NSCLC patients treated with chemotherapies after PD-(L)1 progression.

As of this data cut, 30% of the patients in Cohort A and 26% of the patients in Cohort B are still alive. HS-110 has a favorable safety profile and has been administered in approximately 200 patients to date. As of this data cut, there have been no treatment-related serious adverse reactions. A review of immune-related adverse events reported in the study raised no safety concerns. The data to date demonstrate that combination of HS-110 and nivolumab is well-tolerated.
