Takeda to Acquire Nimbus Therapeutics’ Highly Selective, Allosteric TYK2 Inhibitor to Address Multiple Immune-Mediated Diseases

Nimbus to receive $4 billion in upfront cash, and up to $2 billion in commercial milestone payments

NDI-034858 has potential best-in-class profile among new therapeutic class of selective allosteric TYK2 inhibitors for immune-mediated diseases –

BOSTON, Mass. – December 13, 2022 – Nimbus Therapeutics, LLC (“Nimbus Therapeutics” or “Nimbus”), a clinical-stage company that designs and develops breakthrough medicines through its powerful computational drug discovery engine, today announced that it has signed a definitive agreement under which Takeda (TSE:4502/NYSE:TAK) will acquire Nimbus Lakshmi, Inc., a wholly-owned subsidiary of Nimbus Therapeutics, and its tyrosine kinase 2 (TYK2) inhibitor NDI-034858. NDI-034858 is an oral, selective allosteric TYK2 inhibitor being evaluated for the treatment of multiple autoimmune diseases following successful recent Phase 2b results in psoriasis.

“Nimbus’ allosteric TYK2 inhibitor has the potential to be a best-in-class medicine in multiple disease areas, and we are confident that Takeda’s commitment and capabilities will enable NDI-034858 to reach its full value to patients,” said Jeb Keiper, M.S., MBA, Chief Executive Officer of Nimbus. “The proposed acquisition highlights Nimbus’ ability to discover and develop high-value investigational medicines leveraging our computational structure-based drug design and development engine. We will continue to advance other exciting target programs in our R&D pipeline — including our selective HPK1 inhibitor, currently in a Phase 1/2 study in patients with solid tumors — as we have done since our founding in 2009.”

Under the terms of the agreement, Takeda will pay Nimbus Therapeutics $4 billion upfront, and sales-based milestone payments up to $2 billion. The transaction is expected to be finalized in the first half of 2023. Closing of the transaction is contingent on completion of review under antitrust laws, including the Hart-Scott-Rodino (HSR) Antitrust Improvements Act of 1976. Nimbus Therapeutics will retain ownership of its other research and development subsidiaries. Takeda will be solely responsible for future development and commercialization of NDI-034858 and other TYK2 inhibitors.

J.P. Morgan Securities LLC is acting as exclusive financial advisor to Nimbus Therapeutics and Goodwin Procter LLP is serving as its legal advisor.

About NDI-034858

NDI-034858 is an allosteric TYK2 inhibitor discovered and developed by Nimbus Therapeutics that is being evaluated for the treatment of multiple autoimmune diseases. In preclinical studies, NDI-034858 has demonstrated exceptional functional selectivity and wide therapeutic margins. In Phase 1 studies, NDI-034858 showed a good tolerability profile, a dose-dependent trend in exploratory clinical activity and a pharmacokinetic profile allowing for once-daily solid oral dosing. Results from Nimbus’ Phase 2b clinical trial in patients with moderate-to-severe plaque psoriasis demonstrated a significantly greater proportion of patients in the study achieving the primary endpoint of PASI-75 (a 75% improvement in skin lesions as measured by the Psoriasis Area and Severity Index) compared to placebo after twelve weeks of treatment. Data from this trial will be presented at an upcoming medical conference. In addition to psoriasis, NDI-034858 is in an ongoing Phase 2b trial in active psoriatic arthritis (NCT05153148).
