Study Endpoints

Primary Endpoints

Participants will record the number of flushing per day in a daily diary to assess the efficacy of paltusotine vs placebo in reducing flushing episodes.
Measured at Week 12

Treatment group difference of change from baseline to Week 12 in flushing episodes/day averaged over the 14 days prior to Week 12.

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

Responder Criteria Was Based on the Mean of Two Consecutive Insulin-like Growth Factor-1 [IGF-1] Measurements ≤ULN at Week 13
13 Weeks

Proportion of subjects who meet responder criteria (based on the mean of two consecutive IGF-1 measurements ≤ upper limit of normal \[ULN\])

Secondary Endpoints

Participants will record the number of bowel movements (BMs) per day in a daily diary to assess the efficacy of paltusotine vs placebo in reducing BMs/day.

Frequently asked questions about Paltusotine

What is Paltusotine used for?

Paltusotine is an investigational small molecule being developed for acromegaly and carcinoid syndrome. It is an orally administered drug targeting the somatostatin receptor type 2 (SSTR2) as an agonist. It is not yet approved and is currently in clinical development, with Phase 2 trials completed for acromegaly and a Phase 3 trial ongoing for carcinoid syndrome.

What does Paltusotine target?

Paltusotine targets the somatostatin receptor type 2 (SSTR2), acting as an agonist. By activating SSTR2, it is designed to inhibit the secretion of hormones such as growth hormone and serotonin, which are implicated in acromegaly and carcinoid syndrome. This mechanism is being evaluated in clinical trials for these conditions.

Who makes Paltusotine?

Paltusotine is being developed by Crinetics Pharmaceuticals, Inc., a biopharmaceutical company traded on NASDAQ under the ticker CRNX. The company is conducting clinical trials to evaluate the drug's safety and efficacy for acromegaly and carcinoid syndrome.

What phase is Paltusotine in?

Paltusotine is in Phase 3 clinical development for carcinoid syndrome, with a recruiting trial (NCT07087054). For acromegaly, two Phase 2 trials (ACROBAT Edge and ACROBAT Evolve) have been completed. It has received orphan drug designation from the FDA, but it is not yet approved.

What clinical trials is Paltusotine in?

Paltusotine has been studied in two completed Phase 2 trials for acromegaly: ACROBAT Edge (NCT03789656) with 47 participants and ACROBAT Evolve (NCT03792555) with 13 participants. A Phase 3 trial for carcinoid syndrome (NCT07087054) is currently recruiting, with a planned enrollment of 141 participants.

Is Paltusotine the same as any other drug?

Paltusotine is the sole name provided for this investigational drug; no alternative names have been identified. It is a distinct small molecule being developed by Crinetics Pharmaceuticals for acromegaly and carcinoid syndrome, and it is not known to be marketed under any other brand name.
