Strong Q4 and Full-Year Net Product Revenue Growth
ZYNLONTA net product revenues were $22.3M in Q4 2025 vs $16.4M in Q4 2024 (approximately +36%) and $73.6M for full-year 2025 vs $69.3M in 2024 (approximately +6.2%), with Q4 strength driven by customer ordering variability and activation of new accounts.
Robust Clinical Data from LOTIS-7 and LOTIS-5 Lead-in
LOTIS-7 Phase Ib updated results showed a 90% best overall response rate and a 78% complete response rate across 49 efficacy-evaluable patients (minimum 6-month follow-up). LOTIS-5 safety lead-in reported an 80% overall response rate and 50% complete response rate, supporting potential competitive second-line efficacy.
Clear Near-Term Development Catalysts and Timelines
Management expects LOTIS-5 top-line PFS data in Q2 2026 (study powered for 262 events) with full results by year-end 2026 and potential sBLA/compendia activity in H1 2027; LOTIS-7 full data and publications are planned by end of 2026, and IIT indolent lymphoma data expected between end-2026 and mid-2027.
Significant Cost Reductions and Improved Operating Efficiency
Company implemented strategic reprioritization and reduced operating cost structure by ~50%. Total adjusted operating expenses were $39.4M in Q4 and $181.3M for full-year 2025, down ~15% (quarter) and ~6% (year) versus prior periods, driven primarily by lower R&D and broad expense reductions.
Improved GAAP Results and Adjustments
GAAP net loss improved to $6.4M in Q4 2025 ($0.04 per share) from $30.7M in Q4 2024, and full-year net loss improved to $142.6M in 2025 from $157.8M in 2024, reflecting catch-up adjustment gains related to the deferred royalty obligation and lower R&D spend.
Strengthened Balance Sheet and Extended Runway
Ended 2025 with $261.3M cash and equivalents (up from $250.9M at year-end 2024, ~+4.1%). Company completed a $100M PIPE in June 2025 and a $60M PIPE in October 2025 and expects cash runway at least into 2028.
Commercial Footprint and Market Position
Established ~10% share in third-line plus DLBCL as a monotherapy; field force covers ~90% of DLBCL potential; management expects incremental commercial and MSL investments prelaunch to support second-line expansion if trials succeed.
