Seal Rock Therapeutics Announces Out-Licensing Agreement with GENFIT for Development of Injectable Formulation of SRT-015 for Acute on Chronic Liver Disease (ACLF)

Seal Rock eligible to receive payments up to €100 million, including regulatory, clinical,
and commercial milestone payments, plus tiered royalties

May 31, 2023, Seattle, WA – Seal Rock Therapeutics, Inc., a clinical stage company
developing first-in-class and best-in-class kinase inhibitors, today announced it has
entered into an out-licensing agreement with GENFIT (Nasdaq and Euronext: GNFT) for
the development of an injectable formulation of SRT-015 for acute liver disease,
including Acute-on-Chronic Liver Failure (ACLF).

Under the agreement, Seal Rock Therapeutics is eligible for payments up to €100
million, including regulatory, clinical, and commercial milestone payments, plus tiered
royalties.

SRT-015, a highly optimized, second generation, liver-selective inhibitor of Apoptosis
Signal-reducing Kinase 1 (ASK1). It is being developed by Seal Rock Therapeutics, in
an oral formulation, as a treatment for severe acute alcoholic hepatitis as well as orphan
liver diseases and NASH.

“We’re excited to announce this licensing deal with GENFIT that will accelerate the
development of an injectable formulation of our second-generation ASK1 inhibitor SRT-
015 for ACLF, a liver disease with high unmet need,” said Neil McDonnell, CEO of Seal
Rock Therapeutics. “At Seal Rock, we remain focused on initiating a Phase 2a trial of
oral SRT-015 for severe alcoholic hepatitis. We will also continue development of our
first-in-class LRRK2/ASK1 dual kinase inhibitors for Parkinson’s Disease and ALS.”

“Considering its liver-centric activity, the potential for multi-organ benefits and the
breadth of evidence supporting further development in ACLF, we strongly believe in the
potential of SRT-015,” said Pascal Prigent, CEO of GENFIT. “We are pleased to have
this opportunity to develop a new, injectable formulation of SRT-015 for Acute on
Chronic Liver Failure (ACLF).”
