Syndax Pharmaceuticals Inc (SNDX)·Q3 2025 Earnings Summary
Executive Summary
- Q3 revenue was $45.9M, +21% q/q, driven by $32.0M Revuforj net revenue (+12% q/q) and $13.9M collaboration revenue from Niktimvo; cash and investments were $456.1M .
- Versus S&P Global consensus, revenue slightly missed ($45.9M vs $48.0M) while EPS beat (-$0.70 vs -$0.71); mix was impacted by higher gross-to-net and a modest channel drawdown; inventory remained 2–3 weeks (unchanged) . Estimates marked with asterisks are from S&P Global.
- FDA approved Revuforj for R/R NPM1-mutant AML on Oct 24, expanding the R/R addressable population to ~6,500 incident patients; Revuforj was added to NCCN AML Guidelines (category 2A) in late September .
- Management reiterated a path to profitability with a stable opex base; FY25 opex (R&D+SG&A, ex-SBC) was narrowed to $380–$385M from $370–$390M; Niktimvo margin contribution expected at 25–30% near term and to increase over time .
What Went Well and What Went Wrong
- What Went Well
- Revuforj demand strong: TRx rose ~25% q/q; net revenue rose to $32.0M (+12% q/q) despite ~one-third of patients pausing for transplant; management sees building maintenance restarts as a growth driver .
- Second indication secured: Revuforj won FDA approval in R/R NPM1-mutant AML (Oct 24) and was added to NCCN Guidelines in September, materially expanding the R/R opportunity .
- Niktimvo ramp robust: Incyte reported $45.8M net revenue (+27% q/q), with Syndax booking $13.9M collaboration revenue; 90% of U.S. BMT centers have ordered, and ~80% of Q1 starters remain on therapy .
- What Went Wrong
- Revenue was a slight MISS vs Street as higher 340B/Medicare/Medicaid mix lifted gross-to-net; channel inventory modestly drew down; Revuforj net sales growth (+12%) lagged TRx growth (+25%) .
- Opex still high (R&D $56.3M, SG&A $44.9M); while opex narrowed for FY, profitability depends on continued scale in Revuforj/Niktimvo and maintenance dynamics .
- Restart rate post-transplant remains in early build phase (~35–40%), not yet fully offsetting pauses; mgmt expects this to rise over coming quarters .

Earnings Call Themes & Trends
Management Commentary
- “We reported $45.9 million in total revenue for Q3, representing strong 21% growth over the prior quarter… With both medicines, a robust base of new patients are starting each quarter, and a growing number are continuing on therapy.” — CEO .
- “In the one week since approval, we have already engaged with hundreds of physicians… They are enthusiastic to have Revuforj as the first highly efficacious targeted therapy indicated for relapsed/refractory NPM1.” — CEO .
- “We continue to expect the Niktimvo margin contribution… to be in the 25%–30% range in the near term and increase longer term.” — CFO .
- “We expect sales growth to meaningfully accelerate… with the approval in NPM1 and increasing average duration of therapy in KMT2A as more patients receive Revuforj as long-term maintenance post-transplant.” — CFO .
Q&A Highlights
- Duration and restart dynamics: Management guided to KMT2A average duration of 4–6 months in 2025, expanding to 6–12 months in 2026 as maintenance builds; restart rate rose to ~35–40% and is expected to increase .
- Rx vs revenue delta: 25% TRx growth vs 12% sales growth driven by higher 340B/Medicare/Medicaid mix within the 20–25% GTN range and a slight channel drawdown; inventory steady at 2–3 weeks .
- Payer access: Coverage strong (KMT2A ~97% formulary coverage historically); NPM1 claims expected to adjudicate smoothly with NCCN listing and now approval; minimal friction expected .
- Safety: With frontline patients, serious cardiac events appear lower; no change in monitoring; label includes rare torsades case .
- NPM1 launch trajectory: Field deployed immediately; broad prescriber familiarity from KMT2A; company positions to secure dominant share on efficacy, breadth of label .

Key Takeaways for Investors
- Commercial momentum intact: Revuforj and Niktimvo delivered combined Q3 revenues of $45.9M with accelerating demand indicators; NPM1 approval/NCCN inclusion expands the R/R pool and should accelerate growth .
- Near-term optics: Expect occasional disconnects between TRx and reported sales given GTN mix (340B/government) and inventory; inventory policy remains steady at 2–3 weeks .
- Building annuity: Maintenance restarts post-transplant (~35–40% and rising) and earlier-line use support increasing duration and cohort maturation into 2026 .
- Opex discipline: FY25 R&D+SG&A narrowed to $380–$385M (ex-SBC); mgmt highlights a stable expense base and path to profitability with current cash runway .
- Niktimvo leverage: Near-term 25–30% margin contribution to Syndax with potential to expand as volumes scale against a largely fixed expense base .
- Pipeline catalysts: Extensive ASH datasets (menin and CSF1R), EVOLVE-2 enrollment, and REVEAL initiation by YE25 position Revuforj for frontline paths in 2026+ .
- Trading setup: The narrative hinges on NPM1 launch uptake, maintenance restart ramp, and GTN normalization; quarterly volatility around mix/inventory is possible, but the medium-term thesis is improving scale and operating leverage .
