Background:
Lipodystrophy (LD) syndromes are a group of rare disorders that affect how a person s body can store and use fat tissue. Many people with LDs become severely insulin resistant. Some people are insulin resistant because of a variant in the insulin receptor gene. Insulin resistance causes many health problems.
Objective:
To learn if blocking the effects of growth hormone in the body will help people with severe insulin resistance.
Eligibility:
Adults aged 18 to 65 years with either a known variant in the insulin receptor gene or with a diagnosis of partial LD.
Design:
Participants will have 2 hospital stays, about 1 month apart. Each stay will be 3 or 4 nights.
During each hospital stay, participants will have many tests. They will have a physical exam with blood tests. They will have all of their urine collected for a 24-hour period. They will have scans to measure their muscle, bone, and fat tissues. They will have tests to measure metabolism and insulin sensitivity. They may have an optional biopsy of fat tissue.
During the first hospital visit, participants will learn how to give themselves shots of a drug (pegvisomant) that blocks growth hormone. The drug is injected under the skin. Participants will continue to give themselves these shots once a day at home.
After the first hospital visit, participants will talk on the phone with members of the study team once each week. After 2 weeks they will have blood drawn for tests.
Participants will stop the shots after the second hospital visit.

Cost-effectiveness of pasireotide long-acting release in acromegaly: a systematic literature review and methodology assessment

Review

Author: Kossi, Sika Dédé ; Bronikowska, Małgorzata ; Schmidt, Fabian ; Gilis-Januszewska, Aleksandra ; Gueron, Beatrice ; Binowski, Grzegorz ; Jachimowicz, Michał

BACKGROUND:

Acromegaly is a rare and progressive condition caused by excessive secretion of growth hormone and insulin-like growth factor type 1. Pasireotide long-acting release (LAR) is indicated as a second-line therapy for adults with acromegaly who are unsuitable for or unresponsive to surgery and inadequately controlled with first-generation somatostatin receptor ligands (FGSRLs). Although its efficacy and safety have already been established, its cost-effectiveness remains unclear. The primary objective of this study was to systematically assess the cost-effectiveness of pasireotide LAR compared to other second-line medical options, particularly pegvisomant.

METHODS:

A systematic literature review was conducted in May 2024 in Medline, Medline In Process, Web of Science, and the Centre for Reviews and Dissemination (CRD), York. Studies were eligible if they were full or partial economic analyses of pasireotide LAR as a second-line pharmacological treatment for adult patients with acromegaly. Studies not available in English and publications prior to 2009 were excluded. Included articles were assessed for transparency using the appropriate checklists. Data extraction focused on costs, incremental cost-effectiveness ratios and quality-adjusted life years. Formal data synthesis of outcomes was not undertaken due to the small number of studies and notable heterogeneity between them. Methodological assessment involving the evaluation of model inputs, data sources, and their alignment with the evidence on the course of disease and clinical practice was performed to examine the main factors contributing to discrepancies in cost-effectiveness outcomes and assess the credibility of the results.

RESULTS:

Of 160 records identified, six publications met the inclusion criteria. Their findings demonstrated variability. The critical assessment highlighted considerable variability in methodological rigor among the included studies.

CONCLUSIONS:

Evidence on pasireotide LAR's cost-effectiveness versus pegvisomant regimens remains inconclusive. Although two studies indicated that pegvisomant is more cost-effective, the study with the highest methodological credibility found that pasireotide LAR is a cost-effective alternative.

The 15th Acromegaly Consensus Conference in September 2023 updated recommendations on therapeutic outcomes for acromegaly. Since the publication of medical management guidelines in 2018, new pharmacological agents and new treatment approaches have been developed. Fifty-two experts in the management of acromegaly reviewed the current literature and assessed changes in drug approvals, clinical practice standards and management. Current outcome goals were considered, with a focus on the effect of current and emerging somatostatin receptor ligands, the growth hormone receptor antagonist pegvisomant and the dopamine agonist cabergoline on biochemical control, clinical control, adenoma mass and surgical outcomes. Participants assessed factors that determine pharmacological choices, as well as the proposed use of each agent. Here, we present consensus recommendations highlighting how an evidence-based acromegaly management algorithm could be optimized in clinical practice.

Medical treatment in acromegaly: a network meta-analysis

Review

Author: Haidich, Anna-Bettina ; Ilie, Mirela-Diana ; Anagnostis, Panagiotis ; Raverot, Gérald ; Dekkers, Olaf M ; Kaparounaki, Chrysi ; De Alcubierre, Dario ; Goulis, Dimitrios G ; Isidori, Andrea M

Abstract:

Objective:

Acromegaly is a rare disorder caused by a growth hormone-secreting pituitary adenoma. Clinical trial evidence for its management is limited. This study compared medical treatments for acromegaly through a network meta-analysis, assessing biochemical and radiological responses.

Design:

A systematic review and network meta-analysis were conducted following the preferred reporting items for systematic reviews and network meta-analyses guidelines and Cochrane Handbook recommendations (PROSPERO registration: CRD42023364373).

Methods:

PubMed, Scopus, and Web of Science were searched up to June 2024. Included studies were randomized controlled trials and nonrandomized studies evaluating the efficacy or safety of acromegaly treatments. Primary outcomes were the percentage of adjusted insulin-like growth factor 1 (IGF-1) normalization and tumor shrinkage.

Results:

Twenty-seven studies, involving 4131 patients and 11 treatments were included. Pegvisomant was the best treatment for IGF-1 normalization, followed by pasireotide LAR. Both outperformed first-generation somatostatin receptor ligands (SRLs) combined with dopamine agonists (odds ratio [OR], 1.83; 95% CIs, 1.37-2.46 and OR, 1.46; 95% CIs, 1.02-2.08, respectively; I2 = 41%). Octreotide LAR was superior to oral octreotide capsules (OR, 5.41; 95% CIs, 1.89-15.52). For tumor shrinkage, pasireotide LAR was more effective than SRLs (n = 1059; OR, 11.47; 95% CIs, 1.5-87.64; I2 = 0%). Methodological heterogeneity may have affected comparability.

Conclusions:

Our findings suggest pasireotide LAR and pegvisomant as the most effective treatments for IGF-1 normalization. Pasireotide LAR was the best treatment for tumor shrinkage, though the evidence base was limited, requiring cautious interpretation. Their potential role as first-line options after surgery requires further research. Clinical decisions should consider cost, safety, and patient-specific parameters to optimize outcomes.

Marea Therapeutics Presents Preclinical Data on Novel Growth Hormone Receptor Antagonist Antibody, MAR002, for the Treatment of Acromegaly at ENDO 2025

SOUTH SAN FRANCISCO, CA, USA I July 14, 2025 I Marea Therapeutics, Inc., 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 presentation of preclinical data on MAR002, a novel growth hormone receptor (GHR) antagonist antibody for the treatment of acromegaly, at the 2025 Annual Meeting of the Endocrine Society (ENDO). The oral presentation, titled “Development of a Novel Growth Hormone Receptor Antagonist Antibody for the Treatment of Acromegaly,” highlights the significant potential of MAR002 to address critical unmet needs in patients suffering from this rare and highly morbid disease. Presentation highlights include: Marea Therapeutics has completed a GLP-toxicology study to assess MAR002’s safety. The preclinical pharmacology data strongly support advancing MAR002 into clinical development; a Phase 1 first-in-human study is expected to begin in the third quarter of 2025. Marea’s development strategy aims for rapid advancement into acromegaly patients after achieving proof of mechanism in healthy volunteers, with a clear path to approval guided by FDA guidance for IGF-1 normalization. “The preclinical data presented at ENDO 2025 underscore the potential of MAR002 to meaningfully transform the treatment landscape for acromegaly,” said Ethan Weiss, M.D., chief scientific officer of Marea Therapeutics. “With its strong potency, enhanced durability, and favorable developability profile, MAR002 is uniquely positioned to overcome the limitations of current therapies and offer a more effective, targeted approach for patients. We are excited to advance MAR002 into clinical development and bring forward a next generation and potential best-in-class GHR antagonist.” Marea Therapeutics believes MAR002 represents a significant opportunity to replace and expand the market for existing growth hormone receptor antagonists (GHRAs) and could also be used in combination with somatostatin receptor ligands (SRLs), offering a more effective and convenient treatment option for patients with acromegaly. About MAR002 MAR002 is a novel, potent and selective half-life-extended, allosteric, human monoclonal GHRA antibody being developed for the treatment of acromegaly. The PK and PD properties of MAR002 are 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. 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. The current treatment paradigm for acromegaly often involves surgery, performed in over 90% of patients, which achieves remission in about 50% of cases, though this can degrade over time. Medical therapy is required for approximately 65% (around 20,000 in the U.S.) of patients during their disease journey, regardless of their surgical history. Current medical treatments include somatostatin receptor ligands (SRLs) and growth hormone receptor antagonists (GHRAs), such as pegvisomant. However, many patients do not achieve biochemical control with existing therapies. About Marea Therapeutics Marea Therapeutics is a clinical-stage biotechnology company harnessing the latest advances in human genetics to develop first-in-class, next-generation medicines for cardioendocrine diseases. The company’s lead therapy, MAR001, is in Phase 2 clinical development for adults with metabolic dysfunction and high risk for atherosclerotic cardiovascular disease. The company is also advancing MAR002 for the treatment of acromegaly. To learn more, please visit www.mareatx.com and follow us on LinkedIn and X . SOURCE: Marea Therapeutics

Crinetics Bags Second Phase III Win for Acromegaly, Heads for NDA Submission

Pictured: Blood sample for insulin-like growth factor-1 (IGF-1)/iStock, Jarun011 Crinetics Pharmaceuticals has secured another late-stage win as its oral, once-daily investigational drug paltusotine aced a second Phase III study for acromegaly, a rare hormonal disorder. The biotech’s stock shot up over 10% Tuesday morning following the announcement. In the late-stage trial, 56% of patients taking paltusotine achieved the primary endpoint for the insulin-like growth factor 1 (IGF-1) level compared to 5% on placebo. The treatment also helped reduce symptoms of the disease—a secondary endpoint of the study. No serious adverse events were reported. Acromegaly, sometimes referred to as gigantism, is a serious hormonal disorder caused by a benign tumor in the pituitary gland that secretes growth hormone. Over 25,000 patients in the U.S. suffer from the rare disease, which results in enlargement of face, hands and feet. Left untreated, it can cause type 2 diabetes, hypertension, heart disease and other serious complications. Surgical removal of the tumor is the preferred treatment but many patients are not candidates for surgery. Current pharmacological options include painful monthly injections or Pfizer’s subcutaneous daily injection of Somavert. The Phase III data are the second positive trial results for Crinetics in acromegaly. In September 2023, the biotech shared data for a study of paltusotine in patients who switched from their current injections to Crinetics’ pill. Among treated patients, 83% were able to maintain their IGF-1 levels within the upper limit of normal, compared to only 4% of those on placebo. With these data in hand, Crinetics plans to submit its New Drug Application to the FDA in the second half of this year, while prepping for a 2025 launch. Jefferies analysts believe the market opportunity could be around $300 million for the company. Crinetics is also testing the drug candidate in carcinoid syndrome, reporting positive Phase II topline results last week. Kate Goodwin is a freelance life science writer based in Des Moines, Iowa.
