PTC Therapeutics, Inc. reported that it received a Complete Response Letter from the U.S. Food and Drug Administration regarding its New Drug Application for vatiquinone. This application sought approval of vatiquinone to treat children and adults living with Friedreich’s ataxia, a rare neurodegenerative disease. The company disclosed this development through a press release furnished as an exhibit to this current report.
The Complete Response Letter means the FDA has completed its review of the application but did not approve vatiquinone in its current form, and additional steps would be required before any potential approval. No financial results or updated guidance are discussed in this report.
PTC Therapeutics (PTCT) filed a Form 144 notifying the proposed sale of 2,813 common shares held at Fidelity Brokerage Services, with an aggregate market value of $136,646.45, and an approximate sale date of 08/15/2025 on NASDAQ. The shares were acquired on 08/15/2025 via an option granted 02/15/2024 and payment will be in cash.

Armistice Capital and Steven Boyd report collective ownership of 4,735,464 shares of PTC Therapeutics common stock, representing 5.96% of the class. The shares are held by Armistice Capital Master Fund Ltd., for which Armistice Capital acts as investment manager and exercises shared voting and dispositive power.

On 5 Aug 2025, PTC Therapeutics (PTCT) entered a Rights Satisfaction Agreement with holders of roughly 90% of former Censa Pharmaceuticals equity. The deal cancels the royalty-style Net Sales Payments—8% on annual sepiapterin sales ≤ $250 M, 10% on sales > $250 M ≤ $500 M, and 12% on sales > $500 M—originally embedded in the 2020 Censa merger.
In exchange, PTC paid an up-front cash consideration of ≈ $225 M at closing and agreed to up to five additional milestone payments of ≈ $90 M each (aggregate ≈ $450 M) tied to cumulative global sepiapterin net-sales thresholds of $3 B, $5 B, $7 B, $9 B and $11 B achieved within rolling periods of 3–11 consecutive years. Any former Censa holder that later joins the agreement will receive its pro-rata share of the up-front and any future milestones.
The arrangement only affects the specified Net Sales Payments; all other contingent obligations under the original merger agreement remain intact. The agreement contained customary reps, warranties and covenants and closed simultaneously with signing.
PTC Therapeutics, Inc. (PTCT) Form 144 filing: An insider has notified intent to sell up to 10,739 common shares through Fidelity Brokerage around 05 Aug 2025. Based on the stated aggregate market value of $555,662.71, the proposed sale is priced near $51.75 per share. The shares were obtained via restricted-stock vesting on 01 Aug 2025 and will be sold on Nasdaq.
The block represents roughly 0.014 % of PTCT’s 79.26 million shares outstanding, implying negligible dilution or liquidity impact. While the monetary size is modest for a company of PTCT’s scale, the filing indicates near-term insider profit-taking shortly after vesting, a datapoint some investors watch as a sentiment signal.
