Is this trial a fit for you?

Likely a good fit

Healthy men aged 18–40 years, weighing 55–95 kg with BMI 18–30 kg/m2 and no significant medical history, are the intended participants.

Probably not a fit

Women and people with pituitary disease, active infections, recent investigational drug exposure, substance or nicotine use, or a history of cancer are unlikely to be eligible or to receive direct benefit from this Phase 1 safety study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

MAR002 is given by subcutaneous injection to healthy male volunteers in a Phase 1 interventional trial to characterize safety and tolerability. Eligible participants who meet weight and BMI requirements will be randomized to receive MAR002 or placebo and will undergo clinical monitoring, laboratory testing, and adverse event reporting. Key exclusion criteria include prior pituitary disorders, recent acute illness or blood donation, positive HIV/hepatitis tests, substance or nicotine use, and a history of cancer. The single-site study is sponsored by Marea Therapeutics and conducted in Tempe, Arizona.

Why it matters

Potential benefit: If MAR002 is shown to be safe in healthy volunteers, it could enable further testing that might lead to a new treatment option for people with acromegaly.

How similar studies have gone: Monoclonal antibody approaches have been applied to endocrine disorders with some success, but MAR002 is a novel agent with limited public clinical data.
