This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved

Summary

This phase 2 trial tests whether the experimental drug VHB937 can slow the decline in function and delay the need for breathing support in people with early-stage ALS. About 251 participants will receive either VHB937 or a placebo for 40 weeks, followed by an open-label extension where everyone can get the drug. The study is currently active but no longer recruiting.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
VHB937 (a biologic drug given by infusion)
What this could lead to
If it works, this could point toward a treatment that slows the progression of ALS and delays the need for breathing support.
What could go wrong
This is a mid-stage trial with only 251 people, so results may not apply to all ALS patients. The drug may not show benefit over placebo, and side effects are possible.

Inclusion Criteria: * are 18 years of age or older * male or female, if of childbearing potential, strict contraception required * have ALS confirmed by the trial doctors using different tests. * have mild symptoms of ALS as measured by the ALSFRS-R questionnaire (total score \>=30). * have had symptoms of ALS (weakness) within 24 months of taking part in this trial. * have not received treatment for ALS or are currently on a stable dose of an approved treatment for ALS. * have the ability to slowly exhale a volume of air at least 60% of what is expected for the participant's sex, height and age. Exclusion Criteria: * Use of other investigational drugs within 5 half-lives of screening, or within 30 days (e.g., small molecules) / or until the expected pharmacodynamic effect has returned to baseline (e.g., biologics), whichever is longer; or longer if required by local regulations. * Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception while taking study treatment and for 24 weeks after stopping study medication. * History or current diagnosis of cardiac conditions or ECG abnormalities indicating significant risk of safety for participants in the study. * Clinical evidence of liver or renal disease/injury. * Laboratory evidence of hematological abnormalities * Presence of unstable psychiatric disease, cognitive impairment, neurological disease other than ALS, dementia or substance abuse that would impair ability of the participant to provide informed consent, in the investigator's opinion. * Participants that reported 'yes' on any suicidal ideation section except for the "Non-Suicidal Self-Injurious Behavior" in the past 2 years as per C-SSRS. * Presence of cancer, HIV, Hep B, Hep C, tuberculosis, uncontrolled diabetes * History of active severe respiratory disease, including Chronic Obstructive Pulmonary Disease, interstitial lung disease or pulmonary fibrosis. * Taking any prohibited medications
