Brief Summary:
The purpose of this study is to assess the safety and efficacy of extended dosing with IONIS GHR-LRx in participants with acromegaly as add-on to somatostatin receptor ligands (SRL) therapy.

Condition or disease Intervention/treatment Phase
Acromegaly Drug: IONIS GHR-LRx Drug: SRL Phase 2

Detailed Description:
This extension study will include participants up to 60 participants with acromegaly from Study NCT03548415. All participants will remain on the same dose from the previous study and receive IONIS GHR-LRx (SC) injection once every 28 days as add-on to SRL therapy for 53 weeks. At the end of 53 weeks, participants will enter a 14-week post-treatment (PT) evaluation period.
