What the study statuses mean

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
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early This study
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

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
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests an oral drug called paltusotine in 111 adults with acromegaly, a condition causing abnormal growth due to high hormone levels. Participants are not currently on other treatments. The main goal is to see if the drug safely lowers insulin-like growth factor-1 (IGF-1) levels to normal, helping control the disease.

Willing to provide signed informed consent Exclusion Criteria: 1. Pituitary radiation therapy within 3 years of Screening 2. Prior treatment with paltusotine 3. History of ineffective or intolerance to octreotide or lanreotide 4. History or presence of malignancy except adequately treated basal cell and squamous cell carcinomas of the skin within the past 5 years 5. Use of any investigational drug within the past 30 days or 5 half-lives, whichever is longer 6. Known history of HIV, hepatitis B, or active hepatitis C 7. History of alcohol or substance abuse in the past 12 months 8. Any condition that in the opinion of the investigator would jeopardize the subject's appropriate participation in this study 9.
