Eligibility
Inclusion criteria
* Subject has active acromegaly defined as elevated GH and IGF-1 levels (measured at a central laboratory) as outlined below: * A serum level for IGF-1 ≥1.3 x upper limit of normal range (ULN) during the screening period (applicable to both treatment naïve subjects and subjects who have stopped treatment and undergone a washout period prior to Visit 1(Week -4). * Subjects must have mean serum GH concentration ≥2.5 μg/L in a GH cycle (5 samples taken at 0, 30, 60, 90 and 120 minutes) during the screening period. * The subject has undergone surgical removal of an adenoma for acromegaly at least 3 months prior to Screening, or is likely to require pituitary surgery in the future but not before completing at least 32 weeks of study treatment plus an additional follow up of 8 weeks for subjects taking part in the pharmacokinetics (PK) extension, or for whom pituitary surgery is not an option (due to contraindications, refusal etc.) and is therefore never likely to undergo pituitary surgery.

Back-transformed results are presented in addition to the results without back-transformation. For each subject the IGF-1 SDS value was calculated based on the z-score derivation: IGF-1 SDS = (IGF-1 - mean)/ standard deviation (SD), with mean and SD derived from the upper limit of normal (ULN) and lower limit of normal (LLN) margins for each age category. ULN = Mean + 2 SD; LLN = Mean - 2 SD. The SDS indicates the number of standard deviations away from the mean. A SDS of 0 is equal to the mean with negative numbers indicating values lower than the mean and positive values higher. A negative change in the SDS indicates a decrease in the mean age-adjusted IGF-1 values. |

Recruitment details
Adult subjects with active acromegaly, defined as elevated Insulin-like Growth Factor 1 (IGF-1) and Growth Hormone (GH) levels, were recruited into 10 study sites in China.
Pre-assignment details

| Lanreotide Autogel Subjects were randomised to receive lanreotide Autogel. Lanreotide Autogel was administered s.c. at a fixed dose of 90 mg every 4 weeks from Day 1, Week 1 to Week 17. At Week 17 the dose was continued at 90 mg or titrated to 60 mg or 120 mg every 4 weeks according to the individual subject's response as determined by the mean value of the GH cycles and IGF-1 measured at the previous Week 13 Visit. The last dose of lanreotide Autogel was given at Week 29, followed by EOST/EW Visit at Week 33. | 64 |
| Lanreotide PR Subjects were randomised to receive lanreotide PR. Lanreotide PR was administered i.m. every 10 days from Day 1, Week 1 up to Week 16. At Week 16 the injection interval was maintained at 10 days or was adjusted to 7 or 14 days according to the individual subject's response as determined by the mean value of GH cycle and IGF-1 measured at the previous visit at Week 13. The last dose of lanreotide PR was administered at Week 31. The EOST/EW Visit was at Week 32. | 64 |

Outcome results
Standardised Mean Change From Baseline in Age-adjusted IGF-1 Levels at the EOST/EW Visit
The standardised mean change from Baseline in age-adjusted log-transformed IGF-1 standard deviation score (SDS) at EOST/EW is presented for subjects treated with both lanreotide Autogel and lanreotide PR. Back-transformed results are presented in addition to the results without back-transformation. For each subject the IGF-1 SDS value was calculated based on the z-score derivation: IGF-1 SDS = (IGF-1 - mean)/ standard deviation (SD), with mean and SD derived from the upper limit of normal (ULN) and lower limit of normal (LLN) margins for each age category. ULN = Mean + 2 SD; LLN = Mean - 2 SD. The SDS indicates the number of standard deviations away from the mean. A SDS of 0 is equal to the mean with negative numbers indicating values lower than the mean and positive values higher. A negative change in the SDS indicates a decrease in the mean age-adjusted IGF-1 values.

Population: The Per Protocol population consisted of all subjects who were randomised and treated with at least one baseline and at least one postbaseline assessment of the primary efficacy parameter and for whom no major protocol deviations occurred with impact on efficacy assessment.
