Sage (SAGE) Down 20% on Parkinson's Study Missing Primary Goal

Shares of Sage Pharmaceuticals SAGE dropped 19.6% on Wednesday after management shared topline results from the phase II PRECEDENT study (n=86) evaluating its lead neuropsychiatric candidate dalzanemdor in patients with mild cognitive impairment (MCI) associated with Parkinson’s disease (PD).

The study failed to achieve its primary endpoint of demonstrating a statistically significant difference from baseline in participants treated with orally-administered dalzanemdor, when compared to placebo. Per management, the analyses of data also did not indicate any meaningful differences versus placebo in the other exploratory endpoints, such as SCOPA-Cog.

Management also pointed out that 48 patients, which represent more than half of the total study participants, experienced treatment emergent adverse events (TEAEs) ranging from mild to moderate in severity.

Based on these results, management has decided not to pursue the development of dalzanemdor in PD indication. The share price was down likely due to this reason.

Year to date, shares of Sage have lost 42.0% compared with the industry’s 11.2% fall.

Apart from PD, Sage Therapeutics is evaluating dalzanemdor as a potential treatment for patients with cognition dysfunction caused by Huntington’s disease (HD) across three ongoing clinical studies — two phase II studies (DIMENSION and SURVEYOR) and a phase III study (PURVIEW). The candidate is also being evaluated in a mid-stage study for treating cognitive issues associated with Alzheimer’s disease. Data from these studies are expected throughout this year.

SAGE has been under pressure since last year when the FDA decided on zuranolone in postpartum depression (PPD) and major depressive disorder (MDD) indications. While the agency approved the drug for treating PPD, it issued a complete response letter (CRL) in the MDD indication. The drug will be marketed in PPD indication under the trade name Zurzuvae.

Per the CRL, the FDA stated that the NDA filing did not provide substantial evidence of effectiveness to support the approval of zuranolone. Hence, an additional study or studies will be needed.

Though the approval in PPD was positive, MDD is a much larger and more lucrative market opportunity. In addition, the FDA approval for PPD also comes with a back box warning – advising patients not to drive or operate heavy machinery for at least 12 hours after taking Zurzuvae.

Sage Therapeutics has developed Zurzuvae in collaboration with Biogen BIIB. Currently, Sage and Biogen are evaluating the further course of action. Management is yet to notify a future course of action in this regard.

Following the above setbacks and to support Zurzuvae’s commercial launch, Sage Therapeutics implemented a strategic reorganization plan. Based on this plan, the company reduced its workforce by around 40%, focused on the pipeline development of dalzanemdor and lead neurology program, SAGE-324. Like Zurzuvae, SAGE-324 is also being developed in collaboration with Biogen.
