Knopp Biosciences LLC (“Knopp”) is a Delaware limited liability company.  The owners of an LLC are referred to as Members (versus shareholders), and own units (versus shares).  Unlike a typical corporation, an LLC does not pay federal income taxes, but passes its income and losses through to its members.  Another difference is that its governing body is referred to as a Board of Managers (versus a Board of Directors).

Knopp sold its Kv7 program to Biohaven in April 2022. Biohaven (NYSE: BHVN) and its affiliates are advancing the clinical development of the Kv7 program in epilepsy and other neurological disorders. Many former Knopp employees now work for Biohaven. The first Kv7 drug compound, BHV-7000, is currently being tested in a Phase II/III clinical study for the treatment of focal epilepsy. You can learn more about their progress at the Biohaven website: www.biohaven.com.

Knopp spun off its dexpramipexole program (“Dex”) to Areteia Therapeutics, Inc. in June 2022. Areteia initiated three Phase III clinical trials for Dex. The three ongoing Phase III clinical trials for Dex for the treatment of eosinophilic asthma were terminated due to unexpected adverse events in a small subset of patients in the clinical trials. Areteia ceased operations in November 2025.

In April 2022, Knopp received $35 million in cash and Biohaven stock worth $65 million based on the share price when the deal was signed in February 2022. The stock was subsequently sold at an aggregate price of nearly $75 million.  Knopp also received contract rights to future payments based on the achievement of regulatory and sales milestones related to the Kv7 program.   The first milestone payment of $25 million was received in August 2022. 

In May 2024, Knopp and Biohaven agreed to restructure their contract to include May 1, 2024 and May 1, 2025 payments of $75 million each in stock in exchange for a reduction in regulatory milestones and royalties and an elimination of the sales milestones.

In June 2022, Knopp spun off its intellectual property related to its dexpramipexole program (“Dex”) to a new company, Areteia Therapeutics, Inc. Population Health Partners, a consultancy specializing in pharmaceutical development (“PHP”), partnered with Knopp to induce a consortium of institutional investors led by Bain Capital to invest $450 million to advance Dex in three Phase III clinical trials. When the full $450 million was invested, Knopp beneficially owned approximately 30% of Areteia. In November 2025, Areteia ceased operations due to unexpected adverse events in a small subset of patients in their clinical trials. Knopp’s ownership stake in Areteia is now deemed to be worthless.

Knopp is no longer engaged in the development of new therapeutics but is instead a holding company managing a portfolio of equity securities and contract rights for future payments related to sale and spin-off transactions completed in 2022.

The Knopp Board of Managers is comprised of Tom Petzinger, David Adair, Stephen Butts, Benjamin Gomez, Jeffrey McCormick, FJ Lucchino, and Charlie O’Hanlon. Biographic information regarding the Board of Managers can be found under the “About Knopp” tab of the investor portal.
