WALTHAM, Mass., Aug. 3, 2023 /PRNewswire/ -- Syndax Pharmaceuticals (Nasdaq: SNDX), a clinical-stage biopharmaceutical company developing an innovative pipeline of cancer therapies, today reported its financial results for the quarter ended June 30, 2023, and provided a business update.

"On the heels of recently reported positive data from our pivotal AGAVE-201 trial of axatilimab in chronic graft-versus-host disease, we remain on track to achieve several additional important milestones for both of our programs in what is proving to be a transformational year for Syndax," said Michael A. Metzger, Chief Executive Officer. "The AGAVE-201 data underscore axatilimab's ability to provide meaningful benefit to patients suffering from cGVHD, and we are working with our partners at Incyte to potentially submit a BLA filing by the end of 2023."

Mr. Metzger added, "Additionally, we remain on track to report topline pivotal data from the KMT2Ar cohorts of the Phase 2 AUGMENT-101 trial of revumenib for acute leukemias this quarter, followed by a potential NDA filing by the end of this year. We continue to be focused on executing our robust clinical development plans for both axatilimab and revumenib to fully realize their potential as best-in-class medicines."

Recent Pipeline Progress and Anticipated Milestones

Revumenib

• The pivotal Phase 2 portion of AUGMENT-101 is enrolling relapsed/refractory (R/R) patients across distinct trial populations: patients with nucleophosmin mutant (mNPM1) acute myeloid leukemia (AML), patients with KMT2Ar AML, and patients with KMT2Ar acute lymphocytic leukemia (ALL). The Company expects to share topline data from a pooled analysis of the KMT2Ar cohorts in the third quarter of 2023 and submit a New Drug Application (NDA) filing by the end of 2023. The Company also expects to complete enrollment of the mNPM1 AML cohort by year-end 2023.

• The Company has several trials of revumenib ongoing across the treatment landscape in mNPM1 and KMT2Ar acute leukemias that include the following:

• The Company plans to initiate a trial of revumenib with 7+3 cytarabine and daunorubicin chemotherapy followed by maintenance treatment in newly diagnosed patients with mNPM1 or KMT2Ar acute leukemias by year-end 2023.

• A proof-of-concept clinical trial of revumenib in patients with unresectable metastatic microsatellite stable colorectal cancer is enrolling patients, and the Company expects to provide an update on the Phase 1 trial by year-end 2023.

Axatilimab

• In July 2023, the Company and its partner, Incyte, announced positive topline data from the pivotal Phase 2 AGAVE-201 trial of axatilimab, Syndax's anti-CSF-1R antibody, in patients with chronic graft-versus-host disease (cGVHD) following two or more prior lines of therapy. All three dose cohorts, 0.3 mg/kg every two weeks, 1.0 mg/kg every two weeks and 3.0 mg/kg every four weeks, met the primary endpoint by demonstrating overall response rate within the first six months of treatment of 74%, 67% and 50%, respectively (95% Confidence Interval [CI]: [63,83], [55,77] and [39,61], respectively). Responses were durable and accompanied by a reduction in symptom burden in a notably advanced and heavily pretreated patient population. Furthermore, axatilimab was generally well tolerated and the most common adverse events were consistent with on target effects and prior trials. Syndax and Incyte expect to submit a Biologics License Application (BLA) filing by year-end 2023, pending agreement from regulatory authorities.

• Incyte and Syndax expect to initiate a trial assessing axatilimab in combination with Jakafi^® in cGVHD by year-end 2023.

• The Company expects to initiate a randomized, double-blind and placebo-controlled Phase 2 trial that assesses the efficacy, safety and tolerability of axatilimab in patients with idiopathic pulmonary fibrosis (IPF) by year-end 2023.

Second Quarter 2023 Financial Results

As of June 30, 2023, Syndax had cash, cash equivalents, and short- and long-term investments of $418.3 million and 69.7 million common shares and prefunded warrants outstanding.

Second quarter 2023 research and development expenses increased to $34.8 million from $29.7 million for the comparable prior year period. The increase in research and development expenses was primarily due to increased employee-related expenses, professional fees and clinical expenses, partially offset by decreased manufacturing activities.

Second quarter 2023 general and administrative expenses increased to $14.9 million from $8.0 million for the comparable prior year period. The increase is primarily due to employee-related expenses and professional fees.

For the three months ended June 30, 2023, Syndax reported a net loss attributable to common stockholders of $44.6 million, or $0.64 per share, compared to a net loss attributable to common stockholders of $37.6 million, or $0.62 per share, for the comparable prior year period.

Financial Update and Guidance

For the third quarter of 2023, the Company expects research and development expenses to be $39 to $43 million and total operating expenses to be $57 to $62 million. For the full year of 2023, the Company continues to expect research and development expenses to be $160 to $175 million and total operating expenses to be $225 to $240 million.
