NEW YORK, Nov. 03, 2025 (GLOBE NEWSWIRE) -- Syndax Pharmaceuticals (Nasdaq: SNDX), a commercial-stage biopharmaceutical company advancing innovative cancer therapies, today reported its financial results for the third quarter ended September 30, 2025, and provided a business update.

“The third quarter was another remarkable period of commercial and pipeline execution for Syndax. Demand remained strong for Revuforj and Niktimvo with over $75 million in combined net sales for the quarter,” said Michael A. Metzger, Chief Executive Officer. “We also furthered our leadership in menin inhibition with the addition of Revuforj to the NCCN Guidelines for R/R NPM1m AML in late September followed by FDA approval in late October. Our expansion into this second indication is underway and we are making great progress driving awareness and generating demand. Additionally, we continue to advance the development of both Revuforj and Niktimvo in the frontline setting, further unlocking their multi-billion-dollar potential.”

Recent Business Highlights and Anticipated Milestones

Revuforj^® (revumenib)

• Achieved $32.0 million in Revuforj net revenue in the third quarter of 2025, representing a 12% increase over the second quarter of 2025. Total Revuforj prescriptions in the third quarter of 2025 were approximately 850, a 25% increase over total prescriptions in the second quarter of 2025.
• Received U.S. FDA approval for Revuforj on October 24, 2025, for the treatment of R/R acute myeloid leukemia (AML) with a susceptible NPM1 mutation in adult and pediatric patients one year and older who have no satisfactory alternative treatment options. Revuforj is now the first and only FDA-approved therapy for both R/R AML with an NPM1 mutation and R/R acute leukemia with a KMT2A translocation.
• Announced the inclusion of revumenib in the National Comprehensive Cancer Network^® Clinical Practice Guidelines in Oncology (NCCN Guidelines^®) for AML as a category 2A recommended treatment option for R/R NPM1m AML on September 18, 2025. The guideline update was based on positive pivotal results from the AUGMENT-101 trial of revumenib which were published in the journal Blood in 2025.
• Announced that data from 12 revumenib abstracts, including 3 oral presentations, will be highlighted at the 67^th American Society of Hematology (ASH) Annual Meeting. The abstracts present compelling results with revumenib in multiple acute leukemia subtypes across the R/R, frontline, and post-stem cell transplant settings.
• Multiple trials evaluating revumenib in NPM1m and KMT2Ar acute leukemia across the treatment landscape are ongoing. These trials include:
   
  • EVOLVE-2: A pivotal, Phase 3, randomized, double-blind, placebo-controlled trial evaluating revumenib in combination with venetoclax and azacitidine in newly diagnosed NPM1m AML patients who are unfit for intensive chemotherapy. The trial is being conducted in collaboration with the HOVON network, a leading cooperative clinical trial group with extensive experience studying novel therapies for hematologic malignancies.
  • SAVE: A Phase 1/2 trial evaluating an all-oral combination of revumenib with venetoclax and decitabine/cedazuridine in pediatric and adult patients with newly diagnosed and R/R AML or mixed-lineage acute leukemia (MPAL) harboring either NPM1m, KMT2Ar, or NUP98r alterations. The trial is being conducted by investigators from MD Anderson Cancer Center. Data from the first cohort of newly diagnosed patients will be highlighted at the ASH 2025 Annual Meeting in an oral presentation.
  • Intensive chemotherapy: Two ongoing Phase 1 trials evaluating the combination of revumenib with intensive chemotherapy (7+3) followed by revumenib maintenance treatment in newly diagnosed NPM1m or KMT2Ar acute leukemia patients. Preliminary data from both trials will be presented at the ASH 2025 Annual Meeting.
  • BEAT AML: A Phase 1 trial evaluating the combination of revumenib with venetoclax and azacitidine in newly diagnosed older adults (≥60 years) with NPM1m or KMT2Ar AML. The trial is being conducted as part of the Leukemia & Lymphoma Society's Beat AML^® Master Clinical Trial.
  • Break Through Cancer: A Phase 2 trial studying whether the combination of revumenib and venetoclax can eliminate MRD in patients with AML and extend progression-free survival. The trial is being conducted by Break Through Cancer, a collaboration between leading U.S. cancer research centers.
  • INTERCEPT: A Phase 1 trial evaluating the use of novel therapies, including revumenib, to target MRD and early relapse in AML. The trial is being conducted by the Australasian Leukaemia and Lymphoma Group as part of the INTERCEPT AML master clinical trial.
• Start-up activities are underway for two trials, known as the REVEAL trials, that will evaluate revumenib in combination with standard of care regimens in newly diagnosed acute leukemia patients with NPM1m or KMT2A-rearranged AML who are fit to receive intensive chemotherapy, with trial initiation expected by the end of 2025.
• The Company is evaluating revumenib in patients with R/R metastatic microsatellite stable (MSS) colorectal cancer (CRC). The Company expects to report data from the trial at a medical conference in the first quarter of 2026.
  

Niktimvo™ (axatilimab-csfr)

• Achieved $45.8 million in Niktimvo net revenue in the third quarter of 2025, representing a 27% increase over the second quarter of 2025. Syndax and Incyte are co-commercializing Niktimvo. Syndax records 50% of the Niktimvo net commercial profit, defined as net product revenue minus the cost of sales and commercial expenses. For the third quarter of 2025, Syndax’s share of the Niktimvo product contribution, reported as collaboration revenue, was $13.9 million.
• Announced that data from 11 axatilimab abstracts, including 3 oral presentations, will be showcased at the 2025 ASH Annual Meeting. The abstracts highlight the potential for axatilimab to provide long-term benefit in recurrent or refractory chronic GVHD and the tolerability of axatilimab with ruxolitinib in newly diagnosed chronic GVHD.
• Two trials evaluating axatilimab in combination with standard of care therapies in newly diagnosed chronic GVHD patients are ongoing, including:
  
  
  • A Phase 2, open-label, randomized, multicenter trial of axatilimab in combination with ruxolitinib in patients ≥ 12 years of age with newly diagnosed chronic GVHD.
  • A pivotal Phase 3, randomized, double-blind, placebo-controlled, multi-center trial of axatilimab in combination with corticosteroids in patients ≥ 12 years of age with newly diagnosed chronic GVHD.
• Enrollment is ongoing in MAXPIRe, a Phase 2, 26-week randomized, double-blinded, placebo-controlled trial of axatilimab on top of standard of care in patients with idiopathic pulmonary fibrosis (IPF). The Company expects to complete enrollment in the trial by the end of 2025 with topline data anticipated in the second half of 2026.

Third Quarter 2025 Financial Results

As of September 30, 2025, Syndax had cash, cash equivalents, and short- and long-term investments of $456.1 million and 87.2 million common shares and prefunded warrants outstanding.

Total revenue for the third quarter of 2025 was $45.9 million, which consisted of $32.0 million in Revuforj net revenue and $13.9 million in Niktimvo collaboration revenue. The collaboration revenue is derived from the $45.8 million in Niktimvo net revenue that was previously reported by the Company's partner Incyte. Syndax records 50% of the Niktimvo net commercial profit, defined as net revenue (recorded by Incyte) minus the cost of sales and commercial expenses.

Third quarter 2025 research and development expenses decreased to $56.3 million from $71.0 million for the comparable prior year period. The decrease was primarily the result of a $15 million milestone payment paid by the Company upon Niktimvo's approval, incurred in the third quarter of 2024 and not incurred in the 2025 period. Also contributing to the decrease was lower revumenib-related costs due the completion of the registrational trial in R/R NPM1m AML that was ongoing in the prior period and a reduction in CMC expenses due to the capitalization of inventory for commercial use.

Third quarter 2025 selling, general and administrative expenses increased to $44.9 million from $31.1 million for the comparable prior year period. The increase was primarily due to higher commercial costs and personnel and stock-based compensation expenses related to the commercial launches of Revuforj and Niktimvo in the 2025 period.

For the three months ended September 30, 2025, Syndax reported a net loss attributable to common stockholders of $60.7 million, or $0.70 per share, compared to a net loss attributable to common stockholders of $84.1 million, or $0.98 per share, for the comparable prior year period.

Financial Guidance

For the full year of 2025, the Company expects total research and development plus selling, general and administrative expenses to be $380 to $385 million, compared to prior guidance of $370 to $390 million, both estimates excluding an estimated $45 million in non-cash stock compensation expense.

Syndax expects that its operating expense base will remain stable over the next few years. As a result, Syndax expects that its cash, cash equivalents and short- and long-term investments, combined with its anticipated product revenue and interest income, will enable the company to reach profitability.

About Revuforj^® (revumenib)

Revuforj (revumenib) is an oral, first-in-class menin inhibitor that is FDA approved for the treatment of relapsed or refractory (R/R) acute leukemia with a lysine methyltransferase 2A gene (KMT2A) translocation as determined by an FDA-authorized test in adult and pediatric patients one year and older. Revuforj is also indicated for the treatment of R/R acute myeloid leukemia (AML) with a susceptible nucleophosmin 1 (NPM1) mutation in adult and pediatric patients one year and older who have no satisfactory alternative treatment options.

Multiple trials of revumenib are ongoing or planned across the treatment landscape, including in combination with standard of care therapies in newly diagnosed patients with NPM1m or KMT2Ar AML.

Revumenib was previously granted Orphan Drug Designation for the treatment of AML, ALL and acute leukemias of ambiguous lineage (ALAL) by the U.S. FDA and for the treatment of AML by the European Commission. The U.S. FDA also granted Fast Track designation to revumenib for the treatment of adult and pediatric patients with R/R acute leukemias harboring a KMT2A rearrangement or NPM1 mutation and Breakthrough Therapy Designation for the treatment of adult and pediatric patients with R/R acute leukemia harboring a KMT2A rearrangement.

About Niktimvo™ (axatilimab-csfr)

Niktimvo (axatilimab-csfr) is a first-in-class colony stimulating factor-1 receptor (CSF-1R)-blocking antibody approved for use in the U.S. for the treatment of chronic graft-versus-host disease (GVHD) after failure of at least two prior lines of systemic therapy in adult and pediatric patients weighing at least 40 kg (88.2 lbs).

In 2016, Syndax licensed exclusive worldwide rights to develop and commercialize axatilimab from UCB. In September 2021, Syndax and Incyte entered into an exclusive worldwide co-development and co-commercialization license agreement for axatilimab in chronic GVHD and any future indications.

Axatilimab is being studied in frontline combination trials in chronic GVHD, including a Phase 2 combination trial with ruxolitinib (NCT06388564) and a Phase 3 combination trial with steroids (NCT06585774). Axatilimab is also being studied in an ongoing Phase 2 trial in patients with idiopathic pulmonary fibrosis (NCT06132256).
