Drug Description
This is a Phase 2, double-blind, placebo-controlled, two-way crossover study to compare the efficacy of ALTO-101T versus placebo in change in electroencephalogram (EEG) cognitive processing markers and measures of cognition. Additional goals are to assess pharmacokinetic (PK), safety, and tolerability of the recently developed ALTO-101T transdermal delivery system (TDS) formulation in a patient population.

Executive Summary

Sponsor topline readout for this exact Phase 2 ALTO-101 schizophrenia/CIAS study clearly frames the outcome as negative: it says the trial did not achieve statistical significance on the primary endpoint, did not achieve significance on primary EEG or cognitive endpoints, and Alto will not independently advance ALTO-101 in CIAS.

Reasoning

The trial definitively missed its primary endpoint based on the April 2026 topline release. With NO shares trading around 0.52, this is a clear mispricing. Allocating the maximum allowed capital to buy NO.

Reasoning

Intrinsic 42% < 48.7% YES price (7.6% edge). Buy NO $1000 (max cap) as NO undervalued; no position, ample cash, sells infeasible.
