Progress in the ECLIPSE Program
Vir Biotechnology has successfully enrolled the first patients in ECLIPSE 2 and ECLIPSE 3, with all three registrational studies actively recruiting patients globally. The primary completion for ECLIPSE 1 is expected by December 2026.
Advancements in T Cell Engager Programs
Vir has initiated a Phase I study for VIR-5525, their EGFR-targeted T cell engager, marking their third clinical stage T cell engager program. They also received IND clearance to evaluate VIR-5500 in earlier lines of prostate cancer treatment.
Strong Financial Position
Vir Biotechnology ended the second quarter with approximately $892 million in cash, cash equivalents, and investments, providing a cash runway extending into mid-2027.
Decreased Operating Expenses
Operating expenses in Q2 2025 were $119.6 million, a $42.1 million decrease from the same period in 2024, due to cost savings from restructuring initiatives and reduced stock-based compensation.
ECLIPSE Program Market Potential
The ECLIPSE program targets approximately 7 million active viremic HDV RNA-positive patients globally, with a significant concentration in major urban centers in the U.S., offering a compelling commercial opportunity.
