Key Financial Metrics

Material Changes vs. Prior Period

• Significant Increase in R&D Expenses: R&D expenses surged from $1.1 million in Q1 2024 to $17.3 million in Q1 2025. This increase was primarily driven by a $9.1 million upfront payment and associated transaction costs related to the Mabworks Agreement for CLYM116, plus $6.1 million in expenses for the budoprutug program.
• Increased G&A Expenses: General and administrative expenses rose to $5.7 million from $1.9 million, attributed to increased headcount and higher consulting, legal, and HR costs.
• Investing Activities: The company utilized $42.8 million in net cash for investing activities, primarily purchasing $58.8 million in marketable securities, partially offset by $16.0 million in maturities.
• Share Count: Outstanding shares increased to approximately 67.6 million as of March 31, 2025, following the June 2024 acquisition of Tenet Medicines and related private placement.

Guidance, Outlook, and Risks

• Liquidity Outlook: Management believes current cash, cash equivalents, and marketable securities ($197.8 million) are sufficient to fund operations through 2027. However, the company anticipates needing substantial additional financing in the future.
• Development Milestones:
  • Budoprutug: Received FDA clearance for a Phase 2 trial in primary membranous nephropathy (pMN) in March 2025; first patient dosing expected in H2 2025. Also received clearance for Phase 1b/2a trials in immune thrombocytopenia (ITP) and Phase 1b in systemic lupus erythematosus (SLE), with first patient enrollment expected in H1 2025.
  • CLYM116: Preclinical data expected in H2 2025, with an IND submission for IgA nephropathy anticipated in H2 2025.
• Material Weaknesses in Internal Controls: The company identified material weaknesses in internal control over financial reporting, specifically regarding the control environment and lack of formal accounting policies. Management is implementing remediation efforts, including hiring qualified personnel and improving policies.
• Risk Factors: Key risks include the uncertainty of clinical trial outcomes, dependence on third-party manufacturers and CROs, potential inability to raise additional capital, and significant future milestone payment obligations under license agreements (Acelyrin, CRH, ProBioGen, and Mabworks).

Investor Verification Checklist

• Verify the sufficiency of the $197.8 million cash runway against the accelerated burn rate driven by the new CLYM116 program and expanded budoprutug trials.
• Monitor the progress of the remediation plan for the identified material weaknesses in internal controls over financial reporting.
• Track the timing of the first patient dosing for budoprutug in pMN, ITP, and SLE trials as announced for H1/H2 2025.
• Review the terms of the Mabworks Agreement regarding future milestone payments (up to $832 million) and royalty obligations.
• Assess the impact of potential trade tariffs and geopolitical tensions on supply chains, given reliance on Chinese vendors (e.g., Mabworks, WuXi) for manufacturing and services.
