Second Quarter 2020 Financial Results

Cash Position: Cash, cash equivalents, and marketable securities were $316.5 million as of June 30, 2020, compared to $367.8 million as of December 31, 2019. In addition, the company received an additional $50.0 million milestone payment from Sanofi in the third quarter of 2020.

Revenues: Collaboration revenues were $50.0 million for the three months ended June 30, 2020, compared to $30.0 million for the same period in 2019, for the achievement of clinical development milestones in our Sanofi collaboration.

R&D Expenses: Total research and development expenses were $30.9 million for the three months ended June 30, 2020, including stock-based compensation expense of $3.9 million, compared to $18.7 million for the same period in 2019, including stock-based compensation expense of $1.8 million. The increase in total research and development expenses was mainly driven by an increase in rilzabrutinib program costs, due to the progression of our global Phase 3 trial in pemphigus, ongoing Phase 2 trial in ITP and certain manufacturing campaigns to supply drug products for our rilzabrutinib clinical trials, the initiation of our Phase 1 trial for PRN473 Topical in March 2020 and an increase in employee-related expenses.

G&A Expenses: General and administrative expenses were $9.2 million for the three months ended June 30, 2020, including stock-based compensation expense of $3.1 million, compared to $5.2 million for the same period in 2019, including stock-based compensation expense of $1.7 million. The increase in total general and administrative expenses was primarily driven by increased employee-related expenses and costs related to operating as a public company.

Net Income (Loss): For the three months ended June 30, 2020, net income was $10.8 million compared to net income of $7.1 million for the same period in 2019.

Rilzabrutinib, a reversible covalent BTK inhibitor, is being evaluated in a global Phase 3 clinical trial in participants with pemphigus, a Phase 1/2 clinical trial in participants with immune thrombocytopenia (ITP), and the company plans to initiate a Phase 2 clinical trial in participants with IgG4-Related Diseases and a Phase 3 trial in ITP. PRN2246/SAR442168 is a covalent BTK inhibitor which crosses the blood-brain barrier and is partnered with Sanofi. Sanofi has announced that SAR442168 will be evaluated in four Phase 3 clinical trials in participants with relapsing and progressive forms of multiple sclerosis.
