ALXN2420

Clinical trials are studying ALXN2420 in adults with acromegaly. The main goal is to see whether it can lower IGF-1 levels when used with somatostatin analogs, and to assess its overall effect in this patient group.

Trial overview

The available study is a Phase 2 trial of ALXN2420 in people with acromegaly, a condition being studied in adults.[1] It is an interventional study, which means researchers assign the study treatment and compare results over time.[1]

The trial compares ALXN2420 with placebo, which is a look-alike treatment with no active study drug, and both are given together with somatostatin analogs.[1] The somatostatin analogs listed in the trial are octreotide acetate and lanreotide acetate.[1]

Who can participate

This study is designed for adult participants with acromegaly.[1] The brief summary says the treatment is being tested in adults who are already receiving somatostatin analog therapy.[1]

The trial includes a planned enrollment of 60 participants.[1] This number shows how many people the researchers planned to include in the study.[1]

What is being measured

The main endpoint, or main result the study wants to measure, is the percentage change from baseline in serum IGF-1 level at Week 15.[1] Baseline means the starting value before treatment begins, and serum IGF-1 is a blood marker used to follow disease activity in acromegaly.[1]

The brief summary states that the purpose of the study is to evaluate whether 15 weeks of ALXN2420 treatment can lower IGF-1 levels better than placebo when used with SSA therapy.[1] SSA therapy means treatment with somatostatin analogs.[1]

Trial status and design

The trial status is Suspended, so the study is not actively moving forward at the time shown in the source data.[1] The study is listed as interventional and uses a comparison between ALXN2420 and matching placebo.[1]

Only one trial was provided in the source data, so this article focuses on that single Phase 2 study in acromegaly.[1]

Glossary

  • Acromegaly: A long-term condition caused by too much growth hormone activity, often leading to enlarged hands, feet, and facial features.
  • Adult participants: People in the study who are 18 years of age or older.
  • ALXN2420: The study drug being tested in the trial.
  • Placebo: A look-alike treatment with no active study drug. It is used for comparison.
  • Somatostatin analogs: Treatments that act like somatostatin, a natural body hormone, and are used in acromegaly care.
  • Octreotide acetate: One of the somatostatin analog treatments used in the study.
  • Lanreotide acetate: Another somatostatin analog treatment used in the study.
  • Phase 2: A study stage that checks more closely whether a treatment may work and continues to collect safety information.
  • Interventional study: A trial where researchers assign treatments and then measure the results.
  • IGF-1: Insulin-like growth factor 1, a blood marker used to help track disease activity in acromegaly.
  • Baseline: The starting measurement taken before treatment begins.
  • Week 15: The time point 15 weeks after the start of treatment.
