Recent Business Highlights and Clinical Development Updates

BMS receives FDA approval for mavacamten and presents additional positive Phase 3 clinical trial results

• In April 2022, LianBio’s partner Bristol Myers Squibb (BMS) presented data from two clinical trials of mavacamten at the American College of Cardiology 71^st Annual Scientific Session. Data from the EXPLORER-LTE clinical trial demonstrated sustained improvements in clinically meaningful cardiovascular outcomes at weeks 48 and 84 in patients with symptomatic oHCM receiving mavacamten. Data from the Phase 3 VALOR-HCM clinical trial demonstrated the addition of mavacamten significantly reduced the need for septal reduction therapy (SRT) in patients with severely symptomatic oHCM who had been appropriate for SRT at baseline.
  
  
• In April 2022, BMS announced the U.S. Food and Drug Administration (FDA) approval of mavacamten for the treatment of adults with symptomatic New York Heart Association Class II-III oHCM to improve functional capacity and symptoms.
  

Mavacamten development progress continues in China

• In January 2022, LianBio initiated the Phase 3 EXPLORER-CN clinical trial of mavacamten in Chinese patients with symptomatic oHCM. Patient enrollment is ongoing.

• In May 2022, LianBio announced topline results from the Phase 1 pharmacokinetic (PK) study of mavacamten in healthy Chinese volunteers. A single oral administration of mavacamten in Chinese healthy adult subjects showed no new safety signals. The data demonstrated a favorable PK, safety and tolerability profile comparable to that observed in the Phase 1 pharmacokinetic study of mavacamten conducted by LianBio’s partner, MyoKardia, now a wholly owned subsidiary of BMS, in healthy volunteers in the United States.
  

TP-03 met all primary and secondary endpoints in Tarsus's second U.S. pivotal trial

• In May 2022, Tarsus announced positive topline data from the Phase 3 Saturn-2 clinical trial of TP-03 in Demodex blepharitis (DB) patients. The clinical trial met all primary and secondary endpoints and TP-03 was well-tolerated.
  
  
• Based on these data, Tarsus announced that it will submit a New Drug Application to the U.S. FDA in the second half of 2022.

First Quarter 2022 Financial Results

Research & Development Expenses
Research and development expenses were $12.3 million for the first quarter of 2022 compared to $53.4 million for the first quarter of 2021. The decrease was primarily attributable to increased milestone payments in 2021, and was offset by higher development activities to support clinical trials and personnel-related expenses in 2022.

General & Administrative Expenses
General and administrative expenses were $16.1 million for the first quarter of 2022 compared to $7.1 million for the first quarter of 2021. The increase was primarily attributable to increases in payroll and personnel-related expenses (including share-based compensation expense) for increased employee headcount and higher expense for legal, consulting and accounting services.

Net Loss
Net loss was $27.7 million for the first quarter of 2022 compared to net loss of $61.6 million for the first quarter of 2021.

Cash Balance
Cash, cash equivalents, marketable securities and restricted cash at March 31, 2022 totaled $389.1 million compared to $403.2 million as of December 31, 2021. LianBio projects its current cash, cash equivalents, marketable securities, and restricted cash will be sufficient to fund its current operating plan through mid-2024.
