Exclusion criteria
* Growth hormone (GH) ≥2.5 μg/L at screening (cycle) * Have received medical treatment for acromegaly with pasireotide (within 6 months prior to screening), pegvisomant (within 3 months prior to screening), dopamine agonists (within 3 months prior to screening) or other investigational agents (within 30 days or 5 half-lives prior to screening \[whichever is longer\] * Patients who usually take octreotide LAR or lanreotide ATG less frequently than every 4 weeks (e.g. every 6 weeks or 8 weeks) * Patients with compression of the optic chiasm causing any visual field defect for whom surgical intervention is indicated * Patients who have undergone major surgery/surgical therapy for any cause within 1 month from screening * Patients who have undergone pituitary surgery within 6 months prior to screening * Patients who have received prior pituitary irradiation * Patients with poorly controlled diabetes mellitus (hemoglobin A1c \>8.0%)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of Participants With Mean Insulin-like Growth Factor -1 (IGF-1) Levels ≤1 x Upper Limit of Normal (ULN) at Week 22/24 | Week 22 and 24 | If one of the IGF-1 values at Week 22 or Week 24 was missing, the other value was used to define a responder/non-responder in the analysis. The variable of interest was considered missing only if no IGF-1 value could be obtained from either the Week 22 or the Week 24 sample. A composite strategy was assumed for intercurrent events, and a participant was considered as a non-responder if they discontinued IMP, or had the dose reduced prior to Week 22 (regardless of IGF-1 values), and/or was switched to rescue medication. ULN was derived from the participant's sex and age at screening. In order to account for all participants in the intention-to-treat (ITT) analysis set, multiple imputation was applied. The mean proportion of responders was calculated as an average of responders across the imputed datasets. The resulting proportion was multiplied by 100 to present "Percentage of participants". |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of Participants With Mean IGF-1 Levels ≤1x Upper Limit or Normal (ULN) at Week 22/24, Including Participants With Dose Reduction | Week 22 and 24 | First key secondary endpoint. If one of the IGF-1 values at Week 22 or Week 24 was missing, the other value was used to define a responder/non-responder in the analysis. The variable of interest was considered missing only if no IGF-1 value could be obtained from either the Week 22 or the Week 24 sample. A composite strategy was assumed for intercurrent events, and a participant was considered as a non-responder if they discontinued IMP and/or was switched to rescue medication. For this endpoint, a patient who had their dose reduced was not directly classified as a non-responder. No participant had their dose reduced during the trial. ULN was derived from the participant's sex and age at screening. In order to account for all participants in the ITT analysis set, multiple imputation was applied. The mean proportion of responders was calculated as an average of responders across the imputed datasets. The resulting proportion was multiplied by 100 to present "Percentage of participants" |
| Proportion of Participants With Mean IGF-1 Levels ≤1xULN at Week 22/Week 24 and Mean Growth Hormone (GH) Levels <2.5 µg/L at Week 24 | Week 22 and 24 | Second key secondary endpoint. If one of the IGF-1 values at Week 22 or Week 24 was missing, the other value was used to define a responder/non-responder in the analysis. The variable of interest was considered missing only if no IGF-1 value could be obtained from either the Week 22 or the Week 24 sample or no GH value at Week 24. A composite strategy was assumed for intercurrent events, and a patient was considered as a non-responder if they discontinued IMP or had the dose reduced prior to Week 22 (regardless of IGF-1 values), and/or was switched to rescue medication. ULN was based on the patient's sex and age at screening. In order to account for all participants in the ITT analysis set, multiple imputation was applied. The mean proportion of responders was calculated as an average of responders across the imputed datasets. The resulting proportion was multiplied by 100 to present "Percentage of participants". |
| Proportion of Participants With Mean GH Levels <2.5 µg/L at Week 24 | Week 24 | For the responder analysis of mean GH \<2.5 µg/L at Week 24, a composite strategy was assumed for intercurrent events. A participant was considered as a non-responder if they discontinued IMP, or had the dose reduced prior to Week 24 (regardless of mean GH values), and/or was switched to rescue medication. In order to account for all participants in the ITT analysis set, multiple imputation was applied. The mean proportion of participants was calculated as an average of responders across the imputed datasets. The resulting proportion was multiplied by 100 to present "Percentage of participants". |
| Proportion of Participants With Mean GH Levels <1.0 µg/L at Week 24 | Week 24 | For the responder analysis of mean GH \<1.0 µg/L at Week 24, a composite strategy was assumed for intercurrent events. A participant was considered as a non-responder if they discontinued IMP, or had the dose reduced prior to Week 24 (regardless of mean GH values), and/or was switched to rescue medication. In order to account for all participants in the ITT analysis set, multiple imputation was applied. The mean proportion of participants was calculated as an average of responders across the imputed datasets. The resulting proportion was multiplied by 100 to present "Percentage of participants". |
| Number of Participants With Treatment Emergent Adverse Events | Week 0 to 24 | A treatment emergent adverse event was defined as an adverse event that occurred during or after the first administration of the IMP to the end of trial visit or the next dose of any acromegaly treatment, whichever came first. |
| Proportion of Participants/Partners Declared Competent by a Healthcare Professional to Administer Intervention | Week 0 to 20 and Week 24 | During participants'/partners' first three attempts during the trial period of 24 weeks whenever these visits took place. Percentages were based on those who opted for self-/partner-administration. |
| Octreotide Plasma Concentrations Over Time | Week 0 to 24 | Plasma samples were taken pre-dose on dosing days. |
