What Went Well and What Went Wrong

What Went Well

• Robust efficacy in second-line EBV+ PTCL: “ORR was 60% and the CRR was 30% in the ITT population (n=10); ORR 67% and CRR 33% in EE (n=9)” .
• FDA feedback clarified path: “We received productive feedback from our meeting with the FDA… initiate a randomized controlled trial in 2025 to potentially support registration” .
• Management confidence and clinical momentum: “We believe our sharpened focus on the EBV-positive lymphoma program will propel us forward to key milestones and support our speed to market strategy” – CEO Mark Rothera .

What Went Wrong

• Liquidity/growing concern: Company disclosed substantial doubt about going concern; all amounts under SVB-Oxford loan classified as current liabilities given MAC clause risk .
• Program reprioritization and workforce reduction: paused EBV+ solid tumor program; implemented ~23% RIF, reflecting resource constraints and financing needs .
• DLBCL timeline pushed: Stage 1 DLBCL data moved from “by year-end 2024” to “1H 2025,” indicating schedule slippage .

Guidance Changes

Earnings Call Themes & Trends

Management Commentary

• CEO Mark Rothera: “We received productive feedback from our meeting with the FDA… initiate a randomized controlled trial in 2025 to potentially support registration” .
• CMO Darrel Cohen: “Nana-val demonstrated substantial antitumor activity… with a median duration of response that has not yet been reached… responses were even more robust in the second-line EBV+ PTCL subgroup” .
• CFO Michael Faerm: outlined milestones including Q4’24 expansion data, 1H’25 RCT design meeting, 2H’25 RCT initiation, and 2026 interim/filing aims .
• External KOL (Prof. Porcu): “Complete response rates with Nana-val look very competitive… overall a very competitive position to be in” .

Q&A Highlights

• Trial infrastructure and enrollment: Management plans to leverage >80 global sites, transitioning familiar NAVAL-1 centers into the RCT; enrollment expected to benefit from new data .
• Comparator context: Approved R/R PTCL agents have ~25% ORR, ~10–15% CRR and ~8–9 month DOR; EBV+ subgroup is harder to treat—Nana-val’s second-line outcomes “far exceeded” these .
• FDA “compelling” bar: No numeric bar set; second-line ORR in the 60–67% range viewed as compelling in context; primary analyses will focus on 2L subgroup at interim/final .
• Financing options: Company evaluating multiple alternatives; solid tumor program could be monetized or partnered contingent on financing .
• Transplant objective and DOR: Some patients proceeded to allo-HSCT; DOR assessed both including/excluding transplant outcomes; emphasis on early treatment in EBV+ PTCL .

Estimates Context

• S&P Global Wall Street consensus for Q2 2024 EPS and revenue was unavailable at the time of request; no estimate comparison can be provided. The company does not report product revenue and remains a clinical-stage entity .

Key Takeaways for Investors

• The quarter strengthened the regulatory narrative: FDA alignment plus strong 2L EBV+ PTCL efficacy sets up 2025 RCT initiation and a 2026 accelerated filing aim; near-term catalysts include Q4’24 expansion cohort data .
• Operating discipline: OpEx reductions drove EPS improvement YoY; cash of $30.0M supports operations late into Q1 2025, but going-concern language and current classification of debt warrant close monitoring of financing actions .
• Clinical differentiation: Second-line ORR/CRR and not-yet-reached DOR suggest a competitive profile in a high-need EBV+ PTCL population, potentially enabling expedited pathways if durability holds .
• Strategy sharpened: Pausing solid tumors and implementing a 23% RIF should extend runway and focus resources on registrational EBV+ lymphoma efforts; risk is delayed diversification .
• Trading implications: Watch for Q4’24 expansion data and any financing announcements; positive second-line durability updates or RCT design clarity could be stock catalysts; downside risk from dilution or delays.
• Medium-term thesis: If RCT interim is positive and NAVAL-1 expansion confirms compelling ORR/DOR, Nana-val could address a distinct EBV+ PTCL segment with limited targeted options, supporting valuation re-rating as regulatory milestones approach .
