Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Male and female subjects 18 to 75 years of age
  • Confirmed diagnosis of acromegaly with either a partial or complete response to protocol defined somatostatin analogue therapy regimens
  • Females must be non-pregnant and non-lactating, and either surgically sterile, post-menopausal, or using effective method(s) of birth control
  • Willing to provide signed informed consent

Exclusion criteria

  • Treatment naïve acromegaly subjects
  • Prior treatment with paltusotine
  • Pituitary surgery within 6 months prior to Screening. Subjects receiving radiation therapy may be eligible with some restrictions.
  • History or presence of malignancy except adequately treated basal cell and squamous cell carcinomas of the skin within the past 5 years
  • Use of any investigational drug within the past 30 days or 5 half-lives, whichever is longer
  • Positive test at Screening for HIV, hepatitis B surface antigen (HBsAg) or hepatitis C antibody (HCV-Ab) or has a history of a positive result
  • History of alcohol or substance abuse in the past 12 months
  • Any condition that in the opinion of the investigator would jeopardize the subject's appropriate participation in this study
  • Cardiovascular conditions or medications associated with prolonged QT or those which predispose subjects to heart rhythm abnormalities
  • Subjects with symptomatic cholelithiasis
  • Subjects with clinically significant abnormal findings during the Screening Period, and 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
  • Subjects taking octreotide LAR at a dose higher than 40 mg, or lanreotide depot at a dose higher than 120 mg, or pasireotide LAR at a dose higher than 60 mg
  • Subjects who usually take octreotide LAR or lanreotide depot less frequently than every 4 weeks (e.g. every 6 weeks or 8 weeks)

Treatment and study plan

Paltusotine

Drug

Paltusotine, capsules, once daily by mouth

Other names: CRN00808

Primary outcomes

  1. Change From Baseline (Median of Screening Values) in Insulin-like Growth Factor-1 (IGF-1) Level

    Time frame: 13 Weeks

    Change from baseline in IGF-1 level at Week 13/End of Treatment (W13/EoT) in Group 1 subjects Efficacy Analysis Set (EAS).

Secondary outcomes

  1. Proportion of Subjects With Their Last IGF-1 Measurement ≤ Upper Limit of Normal (ULN)

    Time frame: 13 Weeks

    The secondary endpoint was the proportion of participants who maintained IGF-1 response, defined as the last assessment before the EoT with IGF-1 ≤1.0× ULN meet responder criteria, in Group 3, 4, and 5 subjects only at W13/EoT

  2. Proportion of Subjects With Their Last IGF-1 Measurements ≤1.5×ULN

    Time frame: 13 Weeks

    Proportion of participants with IGF-1 ≤1.5× ULN at W13/EoT.
