Rhea-AI Filing Summary

Kezar Life Sciences has sold its Sec61-based discovery and development program, including preclinical candidate KZR-261, to Enodia Therapeutics. Kezar received $800,000 at closing and is due an additional $200,000 tied to delivery of inventory or 45 days after closing.

The deal also includes up to $127,000,000 in development, regulatory and commercial milestone payments, plus single digit tiered royalties on future net sales of products derived from the acquired assets. Enodia assumed specified liabilities linked to transferred contracts and the acquired assets, while both parties agreed to customary indemnification capped at $1,000,000 for non-fraud losses.

The transaction carves out only the Sec61 program; Kezar retained its zetomipzomib program, employee contracts, cash, receivables, real property and equipment. A joint press release announcing the deal was issued on March 12, 2026.

Insights

Kezar monetizes its Sec61 platform while retaining upside via milestones.

Kezar Life Sciences transferred all rights to its Sec61-based preclinical assets, including KZR-261, to Enodia Therapeutics. Consideration is heavily back-end loaded: only $1,000,000 near term, with up to $127,000,000 in potential milestones plus single digit royalties on future net sales.

This structure shifts development and funding risk for Sec61 programs to Enodia while preserving economic participation if products succeed. Kezar also kept its core zetomipzomib program and operating assets, indicating Sec61 is now a non-core, partnered economic interest rather than an in-house R&D focus.

The real economic impact depends on Enodia’s ability to advance Sec61-derived products through development, regulatory approval and commercialization, milestones that may take many years and are inherently uncertain in drug development.

Exhibit 99.1

Enodia Therapeutics Strengthens Sec61 Portfolio Through Acquisition of Preclinical Assets from Kezar Life Sciences
Transaction deepens insights into Sec61 selectivity for targeted protein degradation, supporting accelerated development of Enodia’s novel small-molecule inhibitors
PARIS and SOUTH SAN FRANCISCO, Calif. - 12 March 2026 - Enodia Therapeutics, a biotechnology company developing novel small-molecule therapies for targeted protein degradation at the point of synthesis, and Kezar Life Sciences, Inc. (Nasdaq:KZR), a clinical-stage biotechnology company developing novel small molecule therapeutics to treat unmet needs in immune-mediated diseases, today announced that Enodia has acquired Kezar’s assets from its Sec61-based discovery and development program. The acquisition enables Enodia to advance its understanding of Sec61 selectivity mechanisms, expanding biological and translational insights for faster progression toward key clinical milestones.
Under the terms of the purchase agreement between Enodia and Kezar, Kezar will receive an initial upfront payment totaling $1 million, and will receive future payments upon achievement of certain development, regulatory and commercialization milestones, for a potential total of up to $127 million. Enodia has also agreed to pay tiered royalties on net sales.
“Kezar has made significant early advances in the Sec61 field with the discovery of small molecule inhibitors,” said Yves Ribeill, Chief Executive Officer of Enodia Therapeutics. “By integrating Kezar’s extensive preclinical datasets into our selective targeted protein degradation platform, this acquisition enhances our ability to make accelerated, yet informed development decisions across our candidate programs.”
Enodia’s proprietary platform enables selective Sec61 Translocon modulation, a novel approach to inhibit disease-relevant proteins at the point of their synthesis before pathological effects occur, while preserving essential physiological functions. Enodia has built a broad and well-characterized chemical space spanning multiple Sec61 inhibitor families, supported by extensive biological datasets, including proteomics, Cryo-EM and tailored cell line libraries to enable rational small-molecule drug design powered by machine learning. Insights from Kezar’s Sec61-based programs will further strengthen Enodia’s core focus on Sec61-driven selectivity for targeting protein degradation.
“Kezar has spent nearly ten years pioneering research and drug discovery efforts around the Sec61 translocon and continues to have strong conviction in this novel target,” said Chris Kirk, PhD, CEO of Kezar Life Sciences. “The team at Enodia is poised to make great progress in this space, and we are excited to see our efforts being carried on and expanded upon.”
