Syndax Pharmaceuticals Reports Second Quarter 2021 Financial Results and Provides Clinical and Business Update

 

WALTHAM, Mass., Aug. 9, 2021 /PRNewswire/ -- Syndax Pharmaceuticals Inc., ("Syndax," the "Company" or "we") (Nasdaq: SNDX), a clinical stage biopharmaceutical company developing an innovative pipeline of cancer therapies, today reported its financial results for the second quarter ended June 30, 2021. In addition, the Company provided a clinical and business update.

"The second quarter of 2021 was marked by significant progress advancing our pipeline of innovative therapeutics, and we are pleased to share that we have selected a go-forward dose for the pivotal Phase 2 portion of AUGMENT-101 based on favorable findings from the intermediate dose cohort," said Briggs W. Morrison, M.D., Chief Executive Officer of Syndax. "Enrollment in the trial continues, with recently enrolled patients expected to count towards the Phase 2 expansion portion, subject to endorsement of the Phase 2 dose by the U.S. Food and Drug Administration (FDA). We are also excited to announce an important step in our plans to expand development of SNDX-5613 into earlier lines of therapy with the initiation of the first frontline combination trial of a menin inhibitor in the Leukemia & Lymphoma Society's Beat® AML Master Clinical Trial."

"Beyond SNDX-5613, enrollment remains on track in the ongoing global pivotal AGAVE-201 trial of axatilimab in patients with chronic graft versus host disease (cGVHD), and we continue to expect topline data from the trial in 2023. In addition, as previously announced, we anticipate sharing updated results from the recently completed Phase 1/2 trial of axatilimab in cGVHD later this year and remain committed to unlocking the full potential of axatilimab in the growing number of cGVHD patients lacking effective interventions."

Recent Progress and Anticipated Milestones

SNDX-5613

  • In May 2021, the Company reported updated data from the ongoing Phase 1 dose escalation portion of the Phase 1/2 AUGMENT-101 trial of SNDX-5613, a highly selective oral menin inhibitor, in patients with mixed lineage leukemia rearranged (MLLr) and nucleophosmin (NPM1c) mutant relapsed/refractory (R/R) acute leukemias. The updated May data showed that a total of 7/31 patients (23%) have achieved CR/CRh.
                                    
    Based on positive findings from the intermediate dose cohort, in which no dose limiting toxicities were observed, the Company has selected 276 mg of SNDX-5613 every 12 hours in patients who are not receiving a concomitant strong CYP3A4 inhibitor (Arm A) and 163 mg every 12 hours for patients who are receiving a concomitant strong CYP3A4 inhibitor (Arm B), for Phase 2. Enrollment in the trial remains ongoing, with recently enrolled patients expected to count towards the Phase 2 expansion portion, subject to endorsement of the Phase 2 dose by the U.S. FDA.
                                             
  • The Company today announced it will initiate a frontline trial of SNDX-5613 in combination with venetoclax and azacytidine in newly diagnosed acute myeloid leukemia (AML) patients unable to tolerate induction chemotherapy. The trial will be conducted as part of the Leukemia & Lymphoma Society's Beat® AML Master Clinical Trial, a collaborative clinical trial that aims to change the paradigm of AML treatment through a precision medicine approach. SNDX-5613 is the first menin inhibitor to be included in the Beat AML Master Clinical Trial.
                                             
  • The Company also announced today that it plans to initiate a new trial to assess the safety, tolerability, and preliminary anti-leukemic efficacy of SNDX-5613 in combination with chemotherapy in patients with R/R MLLr or NPM1 acute leukemias. The Phase 1b trial, which will be referred to as AUGMENT-102, is expected to enroll up to 27 patients.
                                              
  • In June 2021, the Company announced that the U.S. FDA granted Fast Track Designation (FTD) to SNDX-5613 for the treatment of adult and pediatric patients with R/R acute leukemias harboring an MLLr or NPM1 mutation. FTD is designed to facilitate the development and expedite the review of drugs to treat serious conditions and fulfill an unmet medical need, enabling drugs to reach patients earlier.

Axatilimab

  • In May 2021, Syndax announced that enrollment is complete in the Phase 2 expansion portion of the Phase 1/2 trial of axatilimab, its anti-CSF-1R monoclonal antibody, in patients with cGVHD. The Company continues to anticipate reporting updated results at a medical meeting in the fourth quarter of 2021 for 40 patients, including the 17 patients in the Phase 1 portion and 23 patients from the Phase 2 expansion portion, which evaluated 1 mg/kg of axatilimab every two weeks. At the American Society of Hematology Annual Meeting in December 2020, preliminary data from the Phase 1 portion of the trial were reported during an oral presentation highlighting the tolerability and high response rate of axatilimab in cGVHD patients refractory to multiple therapeutic agents.
                                        
    Enrollment is ongoing in the Company's global pivotal Phase 2 AGAVE-201 trial of axatilimab in patients with cGVHD, with topline data expected in 2023. The trial will evaluate the safety and efficacy of three doses and schedules of axatilimab. The primary endpoint will assess objective response rate based on the 2014 NIH consensus criteria for cGVHD, with key secondary endpoints including duration of response and improvement in modified Lee Symptom Scale score.
                                        
  • Earlier this year, the Company announced that the U.S. FDA granted Orphan Drug Designation to axatilimab for the treatment of patients with cGVHD and idiopathic pulmonary fibrosis.

Second Quarter 2021 Financial Results  

As of June 30, 2021, Syndax had cash, cash equivalents and short-term investments of $253.1 million and 51.9 million shares and share equivalents issued and outstanding. This includes 3.3 million pre-funded warrants.

Second quarter 2021 research and development expenses increased to $16.9 million from $10.9 million for the prior year period. The increase was primarily due to increased clinical trial activities and increased CMC activities.

General and administrative expenses for the second quarter 2021 decreased to $5.8 million from $6.0 million for the prior year period. The decrease is primarily due to the absence of pre-commercialization expenses for entinostat in 2021 partially offset by employee related expenses.

For the three months ended June 30, 2021, Syndax reported a net loss attributable to common stockholders of $22.9 million or $0.44 per share compared to $17.1 million or $0.42 per share for the prior year period.

Financial Update and Guidance

For the third quarter of 2021, research and development expenses are expected to be $25 to $30 million, and total operating expenses are expected to be $30 to $35 million. For the full year of 2021, research and development expenses are expected to be $90 to $100 million, and total operating expenses are expected to be $110 to $120 million.
