Brief summary

The purpose of this study was to determine the safety, tolerability, and efficacy of IONIS-GHR-LRx subcutaneous (SC) injection as monotherapy in patients with acromegaly.

Detailed description

This was a multi-center, open-label, randomized, Phase 2 study of IONIS-GHR-LRx in up to 40 participants with acromegaly. Participants were randomized to 1 of 2 treatment groups to receive IONIS GHR-LRx monthly for 73 weeks. At the end of 73 weeks, participants entered a 14-week post-treatment (PT) evaluation period.

Inclusion criteria

1. Males or females with a documented diagnosis of Acromegaly\* who are 18 to 75 years old (inclusive) at the time of informed consent. 2. Have had pituitary surgery (e.g. transsphenoidal) unless there was a contraindication to surgery and are either acromegaly medical treatment naïve, or who had not taken any other acromegaly medications prior to the screening visit as outlined below * bromocriptine: 2 weeks * cabergoline: 4 weeks * quinagolide: 4 weeks * octreotide daily injection (SC) or oral formulation: 4 weeks * pegvisomant: 4 weeks * octreotide LAR: 3 months * pasireotide LAR: 4 months * lanreotide (all formulations): 3 months 3. At Screening, serum IGF-1 (performed at the central lab) between 1.3 to 5 × ULN, inclusive, adjusted for age and sex. 4. Females must be non-pregnant and non-lactating, and either surgically sterile, post-menopausal, abstinent, or using 1 highly effective method of birth control

Exclusion criteria

1. Participants who received surgery for pituitary adenoma within the last 3 months before the trial, and/or planning to receive surgery during the trial 2. Participants who received radiotherapy for pituitary adenoma within the last 2 years before the trial, and/or planning to receive radiotherapy during the trial 3. Participants with a pituitary tumor that, per Investigator judgment, is worsening (e.g., either growing or at risk of compressing or abutting the optic chiasm or other vital structures) as assessed by pituitary/sellar MRI protocol at Screening or within 3 months of Screening.

Recruitment details

Participants were enrolled at 22 investigational sites in United States of America, Estonia, Hungary, Italy, Latvia, Lithuania, Poland, Romania, Russia, and Serbia from 4 January 2021 to 18Jan2022.

Pre-assignment details

Participants with acromegaly were enrolled and assigned to receive an initial dose of GHR-LRX 120 mg or GHR-LRX 160 mg up to week 17 (when the first post-baseline IGF-1 results were available). After Week 17, patients may have received a higher dose up to 160 mg for efficacy, if necessary, up to 73 weeks.

Percent Change in Insulin-like Growth Factor I (IGF-1) From Baseline to Week 27

IGF-1 is a hormone that manages the effects of growth hormone (GH) in the body. Baseline of IGF-1 is defined as the average value of Screening and Day 1. A negative percent change from Baseline indicated improvement.

Time frame: Baseline to Week 27

Population: Per protocol set (total dose) included all FAS participants who completed at least 6 of the 8 doses of GHR-LRX with the first 27 Weeks administered and have no significant protocol deviations that would be expected to impact efficacy. Total dose includes results for IGF-1 reduction that combines both 120 mg and 160 mg doses. Analysis based on highest dose received as prespecified in the statistical analysis plan (SAP).
