PURCHASE, N.Y., July 29, 2024 (GLOBE NEWSWIRE) -- Cognition Therapeutics, Inc. (the "Company" or "Cognition") (NASDAQ:CGTX), a clinical stage company developing drugs that treat neurodegenerative disorders, today reported that participants in the proof-of-concept Phase 2 ‘SHINE' study (NCT03507790) who were treated with CT1812 for six months showed a consistent trend in cognitive improvement compared to placebo across all cognitive measures including ADAS-Cog 11, ADAS-Cog 13, cognitive composite and MMSE. In addition, there were signals of improvement in functional measures (ADCS-ADL and ADCS-CGIC). Details of these clinical and biomarker findings are reported in posters at the Alzheimer's Association's International Conference on July 29, 2024 in Philadelphia, PA.

"The SHINE trial showed that after 182 days of treatment, CT1812 demonstrated evidence of clinical improvements on cognition coupled with a favorable safety and tolerability profile, particularly in the 100mg dose cohort. These findings will inform dose selection and provide a foundation for advancing to the next stage of clinical development," stated Lisa Ricciardi, president and CEO of Cognition Therapeutics. "We believe these results provide evidence that amyloid oligomer antagonism – a new and distinct mechanism for therapeutic intervention – may have a role as a monotherapy or in a combination with approved drugs for the treatment of AD and related dementias. In terms of percent improvement on evaluated cognitive measures, our results are comparable in magnitude to what was achieved with currently approved antibodies, with great ease of administration as a once daily dose, and less patient burden."

SHINE enrolled 153 adults with mild-to-moderate (MMSE 18-26) Alzheimer's disease who were randomized evenly (1:1:1) to one of two oral daily doses of CT1812 (100mg or 300mg) or placebo. P-values less than 0.05 were observed on ADAS-Cog 11 and MMSE at Day 98, the midpoint of the study. Through the course of the study, participants in the placebo arm worsened approximately 2.70 points as measured by ADAS-Cog 11 on Day 182. In contrast, CT1812-treated participants declined by an average of 1.66 points, a 39% slowing of decline favoring CT1812. Similar results were seen in the MMSE score on Day 98 for the pooled CT1812 arms. On the exploratory measures of function (ADCS-ADL and CGIC), there was a signal of benefit favoring CT1812 at the six-month timepoint. In this study, CT1812 did not achieve statistical significance on the first of the ordered secondary efficacy endpoints in the pooled 100mg and 300mg dose group compared to placebo. CT1812 demonstrated a favorable safety and tolerability profile with most treatment-related adverse events being mild or moderate, consistent with previous clinical experience.

"A key objective of this trial was to provide evidence of cognitive benefit potential with CT1812 treatment, which we accomplished," added Anthony Caggiano, Cognition's CMO and head of R&D. "We are pleased about the consistent cognitive effect and signals of functional benefit across the entire study. We intend to utilize these findings to enable us to design and power future clinical trials to advance the development of CT1812 in Alzheimer's disease. We believe that the data supports the advancement of a 100mg dose of CT1812 in additional clinical trials in a mild-to-moderate patient population." 

While we are continuing to analyze the exploratory CSF biomarker program data, the study showed favorable changes in neurofilament light chain (NfL), which is a marker of neurodegenerative disease. These changes were significant at the 300mg dose. We believe this finding supports the understanding of the potential role of CT1812 as a synaptoprotective agent. Other CSF biomarkers not approaching significance include neurogranin, synaptotagmin, SNAP25, pTau, total Tau and GFAP.

The SHINE study achieved its primary objective and demonstrated a favorable safety and tolerability profile, consistent with previous clinical experience. Overall, the percentage of participants experiencing any adverse event (AE) was similar between the pooled CT1812 treatment arms (76.5%) and the placebo group (78%). The majority of adverse events were mild or moderate in severity. The most commonly reported treatment-emergent adverse events were infections and infestations (urinary tract infection), injury, poisoning and procedural complications (falls and skin lacerations), gastrointestinal disorders and nervous system disorders (headache).

In the placebo arm, 10% of participants experienced a serious adverse event (SAE) compared to 6% in the combined CT1812 treated arms. Among CT1812-treated participants, two experienced treatment-emergent SAEs in the 100mg group, including stomatitis, chronic constipation, and hip fracture (all deemed not related to treatment) and three experienced treatment-emergent SAEs in the 300mg group, including hematuria, abdominal pain, and infection (all deemed not related to treatment) and recurrent presyncope (deemed related to treatment).

At the 300mg dose, nine patients experienced treatment-emergent LFT increases (greater than 3xULN), which subsided after cessation of drug without evidence of serious liver injury. There were no LFT elevations observed in the 100mg dose.

"We are optimistic about the SHINE results and are looking ahead to the results of our SHIMMER trial in mild-to-moderate Lewy body dementia, which is anticipated to read out later this year," stated Lisa Ricciardi, president and CEO of Cognition Therapeutics. "In addition, we are studying patients with early stage Alzheimer's disease in our START trial of 540 patients. Another Phase 2 proof-of-concept trial in dry AMD is currently enrolling patients. Cognition is committed to advancing the field of research to provide clinical options for patients with neurodegenerative disease, and we could not have done this without the grant support of over $170M we have received from the NIH, NIA, ADDF and MJFF."

This and Cognition's other AAIC posters will be available on the Company's Publication webpage in accordance with the conference's embargo policy.

About the SHINE Study

The SHINE study is a double-blind, placebo-controlled Phase 2 clinical trial which enrolled 153 adult patients with mild-to-moderate Alzheimer's disease. Based on the study design, SHINE was powered to detect a 3-point change in ADAS-Cog 11. The primary endpoint was safety and tolerability and the key secondary endpoint cognitive measure was ADAS-Cog 11. Participants were evenly randomized to receive either placebo or one of two doses of CT1812 (100 mg or 300 mg), which was taken orally daily for six months. The SHINE study was supported by two grant awards from the National Institute on Aging of the National Institutes of Health (NIH) totaling approximately $30 million. More information may be found at clinicaltrials.gov under trial ID NCT03507790.

About CT1812

CT1812 is an experimental orally delivered small molecule oligomer antagonist that penetrates the blood-brain barrier and binds selectively to the sigma-2 (σ-2) receptor complex. Preclinical and clinical data demonstrated that this binding resulted in the displacement of toxic Aβ oligomers. The σ-2 receptor complex is involved in the regulation of key cellular processes such as membrane trafficking and autophagy that are damaged by toxic interaction with Aβ oligomers, oxidative stress and other stressors. This damage to sensitive synapses can progress to a loss of synaptic function, which manifests as cognitive impairment and Alzheimer's disease progression.

Participants are currently being recruited in the SHIMMER study (NCT05225415) of CT1812 in adults with dementia with Lewy bodies; the START study (NCT05531656) of CT1812 in adults with early Alzheimer's disease; and the MAGNIFY study (NCT05893537) in adults with geographic atrophy (GA) secondary to dry age-related macular degeneration.

About Cognition Therapeutics, Inc.

Cognition Therapeutics, Inc. is a clinical-stage biopharmaceutical company engaged in the discovery and development of innovative, small molecule therapeutics targeting age-related degenerative disorders of the central nervous system and retina. We are currently investigating our lead candidate CT1812 in clinical programs in Alzheimer's disease, dementia with Lewy bodies (DLB) and dry age-related macular degeneration (dry AMD). We believe CT1812 and our pipeline of σ-2 receptor modulators can regulate pathways that are impaired in these diseases. We believe that targeting the σ-2 receptor with CT1812 represents a mechanism functionally distinct from other current approaches in clinical development for the treatment of degenerative diseases.
