About this trial

This is an interventional treatment trial for Acromegaly focused on measuring Acromegaly, PATHFNDR, Paltusotine, CRN00808

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Male and female subjects ≥18 years of age
  2. Confirmed diagnosis of acromegaly and controlled (as measured by IGF-1 ≤1.0×ULN) via stable dose of protocol defined somatostatin receptor ligand therapy
  3. Females must be non-pregnant and non-lactating, and either surgically sterile, post-menopausal, or using effective method(s) of birth control
  4. Willing to provide signed informed consent

Exclusion Criteria:

  1. Treatment naïve or treatment-withdrawn acromegaly subjects
  2. Prior treatment with paltusotine
  3. Pituitary surgery within 24 weeks prior to Screening or history of pituitary radiation therapy
  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. Cardiovascular conditions or medications associated with prolonged QT or those which predispose subjects to heart rhythm abnormalities
  10. Subjects with symptomatic cholelithiasis
  11. Subjects with clinically significant abnormal findings during the Screening Period, or any other medical condition(s) or laboratory findings that, in the opinion of the Investigator, might jeopardize the subject's safety or ability to complete the study
  12. Subjects currently taking pasireotide LAR (within 24 weeks prior to Screening) or pegvisomant, dopamine agonists (within 12 weeks prior to Screening), or short acting somatostatin analogs (within 12 weeks prior to first dose of study drug)
