Prior Disclosures

Starton is aware that its CEO appeared on the television program “Unicorn Hunters” on June 7, 2021. During that appearance, the CEO made a number of representations as to Starton’s approach to reformulating drug products to improve efficacy, tolerability and patients’ quality of life. As part of these representations, the CEO raised the specific example of Starton’s investigational reformulation of Revlimid™. While Starton believes in the value of its product, it understands that any clinical superiority claims cannot be made absent specific findings from rigorous clinical studies which Starton has not undertaken. The CEO’s comments on the television program were not intended to suggest Starton has conducted such studies; Starton does not have data to support these specific representations and disclaims any representations or purported representations by its CEO which either stated or implied the contrary.
