Marea Therapeutics, a Subsidiary of Lisata Therapeutics, Announces First Patient Dosed in Phase 2 Clinical Trial of MAR002, a Potential Best-in-disease Investigational Therapy for the Treatment of Acromegaly

Trial follows promising MAR002 Phase 1 clinical trial results that demonstrated deep and durable IGF-1 suppression with PK properties that may enable dosing as infrequently as once every two weeks, compared to the daily subcutaneous injections required by the current standard of care

By directly blocking growth hormone signaling at the receptor level, MAR002 has the potential to deliver meaningful biochemical control for a broad population of acromegaly patients

SOUTH SAN FRANCISCO, Calif. and LIBERTY CORNER, N.J., Oct. 05, 2026 (GLOBE NEWSWIRE) -- Marea Therapeutics, LLC (“Marea”), a subsidiary of Lisata Therapeutics, Inc. (Nasdaq: LSTA) (“Lisata”), a clinical-stage biotechnology company harnessing the latest advances in human genetics to develop first-in-class, next-generation medicines for cardioendocrine diseases, today announced the first patient has been dosed in its Phase 2 clinical trial of MAR002 for the treatment of acromegaly.

Acromegaly is a rare, chronic, progressive endocrine disorder caused by prolonged exposure to excess growth hormone (GH), most commonly due to a GH-secreting pituitary adenoma, resulting in elevated insulin-like growth factor-1 (IGF-1). It leads to the abnormal enlargement of the hands, feet, and facial features, and if left untreated, can result in severe organ damage, systemic complications, and early mortality.

MAR002 is a first-in-class allosteric monoclonal antibody investigational therapy targeting the growth hormone receptor (GHR). Data from a first-in-human Phase 1 study with MAR002 presented at the 2026 Annual Meeting of the Endocrine Society (ENDO) in June 2026 demonstrated compelling proof-of-mechanism with deep and durable IGF-1 suppression and pharmacokinetic (PK) properties that may enable dosing as infrequently as once every two weeks, compared to the daily subcutaneous injections required by the current standard of care.

“Treating our first acromegaly patient with MAR002 represents an important milestone for Marea Therapeutics,” said Josh Lehrer, M.D., president and chief operating officer of Lisata Therapeutics and chief executive officer of Marea Therapeutics. “We believe MAR002 has a potential best-in-class profile and, if approved, could be transformative for the majority of acromegaly patients who cannot achieve disease control with current therapies. We are focused on clinical execution to rapidly advance this product candidate to acromegaly patients who need new treatment options.”

“People living with acromegaly often face years of symptoms before receiving a diagnosis, and even after diagnosis, many continue to struggle with the long-term burden of managing this chronic disease,” said Jill Sisco, president of Acromegaly Community, Inc. “The advancement of new treatment options that have the potential to provide effective disease control while reducing treatment burden offers hope for the acromegaly community. We are encouraged to see continued investment in investigational therapies like MAR002 that aim to address the needs and priorities of people living with this condition and expand treatment options.”

This study intends to enroll approximately 72 participants with acromegaly across three MAR002 dose arms, after an initial 900 mg loading dose, compared to placebo, with a primary endpoint of IGF-1 reduction following 10 weeks of treatment. After completing the 10-week treatment period, eligible participants will have an option to enroll in an open-label extension clinical trial.

About Acromegaly
Acromegaly is an orphan disease characterized by the excess secretion of growth hormone (GH) from a benign pituitary adenoma. Acromegaly affects approximately 30,000 patients in the U.S. If left untreated, acromegaly is highly morbid, leading to significant comorbidities such as GH-induced insulin resistance and diabetes, and serious cardiovascular pathology. The median lifespan of patients can be shortened by 10 years without effective therapy, and incomplete IGF-1 normalization is associated with increased mortality. Despite its severity, acromegaly is often under or misdiagnosed, with an average time from symptom onset to diagnosis of approximately eight years.

About MAR002
MAR002 is a potent and selective half-life-extended, allosteric, human monoclonal growth hormone receptor antagonist (GHRA) antibody being developed for the treatment of acromegaly. The in vivo PK and PD properties of MAR002 have been observed to be predictable and typical of a half-life extended human antibody, showing a long duration of action compatible with infrequent subcutaneous dose administration in humans. These characteristics support its potential to offer an effective and convenient treatment for patients with acromegaly, if approved.
