8-K: Syros Pharmaceuticals' Phase 3 Trial Fails to Meet Primary Endpoint, Triggering Loan Default

Syros Pharmaceuticals' SELECT-MDS-1 Phase 3 trial for tamibarotene in higher-risk myelodysplastic syndrome did not meet its primary endpoint, leading to a loan default and discontinuation of the study.

Summary

• Syros Pharmaceuticals announced that its Phase 3 SELECT-MDS-1 trial for tamibarotene in combination with azacitidine did not meet its primary endpoint of complete response rate in patients with higher-risk myelodysplastic syndrome.
• The trial compared a tamibarotene/azacitidine treatment arm to a placebo/azacitidine control arm.
• The complete response rate in the tamibarotene arm was 23.8% compared to 18.8% in the placebo arm, which was not statistically significant.
• The failure of the trial triggered an event of default under Syros' loan agreement with Oxford Finance LLC.
• The total amount of the company's direct financial obligation that may be accelerated is estimated to be approximately $43.6 million.
• Syros plans to discontinue the study, review the full data set, and evaluate next steps.

Industry Context

Comparison to Industry Standards

• The complete response rate of 23.8% in the tamibarotene arm is below the typical benchmarks for successful Phase 3 trials in hematologic malignancies.
• Other companies developing treatments for myelodysplastic syndrome, such as Celgene (now part of Bristol Myers Squibb) with its drug Revlimid, have shown higher response rates in their trials.
• The failure of the trial to meet its primary endpoint is a significant setback for Syros, especially when compared to the success of other companies in the space.

Stakeholder Impact

• Shareholders will likely experience a negative impact due to the trial failure and loan default.
• Employees may face uncertainty regarding the company's future direction.
• Patients with higher-risk myelodysplastic syndrome will not have access to tamibarotene as a treatment option from this trial.
• Creditors, particularly Oxford Finance LLC, will be impacted by the loan default.

Next Steps

• Syros will discontinue the SELECT-MDS-1 Phase 3 trial.
• The company will review the full clinical data set from the trial.
• Syros will evaluate next steps for its clinical development plans.
