What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Determination of the Maximum Tolerated Dose (MTD) by Number of Subjects With DLTs.	The MTD was defined based on the DLTs observed in each cohort. A DLT was defined as an adverse event (AE) (excluding anorexia and fatigue) or an abnormal laboratory value occurring within the first week (up to Week 2) following lanreotide PRF administration and during the entire study duration, assessed as unrelated to acromegaly, intercurrent illness or concomitant medications and which met any of the pre-established toxicity criteria. If no DLTs were reported then no MTD could be defined.	From Day 1 up to Week 25.
PK Analysis of Lanreotide: Maximum Observed Serum Concentration (Cmax).	Blood samples for determination of lanreotide serum concentrations were collected at Baseline (pre-dose), at 1, 2, 4, 6, 8,12 and 24 hours post-dose, on Days 3 and 5 and at Weeks 2, 3, 5, 9 and 13 after lanreotide PRF administration. Samples were also collected during follow-up at Weeks 17, 21 and 25 (or EW). Mean serum lanreotide Cmax values were determined using non-compartmental analysis.	From Baseline (pre-dose) up to Week 25.
PK Analysis of Lanreotide: Time to Reach Maximum Serum Concentration (Tmax).	Blood samples for determination of lanreotide serum concentrations were collected at Baseline (pre-dose), at 1, 2, 4, 6, 8,12 and 24 hours post-dose, on Days 3 and 5 and at Weeks 2, 3, 5, 9 and 13 after lanreotide PRF administration. Samples were also collected during follow-up at Weeks 17, 21 and 25 (or EW). Median serum lanreotide Tmax values were determined using non-compartmental analysis.	From Baseline (pre-dose) up to Week 25.
PK Analysis of Lanreotide: Apparent Terminal Elimination Half-life (t1/2).	Blood samples for determination of lanreotide serum concentrations were collected at Baseline (pre-dose), at 1, 2, 4, 6, 8,12 and 24 hours post-dose, on Days 3 and 5 and at Weeks 2, 3, 5, 9 and 13 after lanreotide PRF administration. Samples were also collected during follow-up at Weeks 17, 21 and 25 (or EW). Mean serum lanreotide t1/2 values were determined using non-compartmental analysis. Only values fulfilling the determination rules for t1/2 were analysed.	From Baseline (pre-dose) up to Week 25.
PK Analysis of Lanreotide: Area Under the Serum Concentration-time Curve From Time 0 to 85 Days (AUC0-85).	Blood samples for determination of lanreotide serum concentrations were collected at Baseline (pre-dose), at 1, 2, 4, 6, 8,12 and 24 hours post-dose, on Days 3 and 5 and at Weeks 2, 3, 5, 9 and 13 after lanreotide PRF administration. Sample were also collected during follow-up at Weeks 17, 21 and 25 (or EW). Mean serum lanreotide AUC0-85 values were determined using non-compartmental analysis.	From Baseline (pre-dose) up to Day 85
PK Analysis of Lanreotide: Area Under the Serum Concentration-time Curve Extrapolated to Infinity (AUC0-∞).	Blood samples for determination of lanreotide serum concentrations were collected at Baseline (pre-dose), at 1, 2, 4, 6, 8,12 and 24 hours post-dose, on Days 3 and 5 and at Weeks 2, 3, 5, 9 and 13 after lanreotide PRF administration. Samples were also collected during follow-up at Weeks 17, 21 and 25 (or EW). Mean serum lanreotide AUC0-∞ values were determined using non-compartmental analysis. Only values fulfilling the accuracy determination rules for AUC0-∞ were analysed.	From Baseline (pre-dose) up to Week 25.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Summary of Number of Subjects With AEs.	AEs reported by the investigators using the National Cancer Institute-Common Toxicity Criteria (NCI CTCAE) classification (Version 4.03) and incidence of all reported treatment emergent AEs (TEAEs) and serious AEs (SAEs) are presented by dose cohort. AEs were assigned to a NCI CTCAE Grade from 1 through 5 as follows: Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe or medically significant but not immediately life threatening or requiring hospitalisation; Grade 4: Life-threatening consequences; Grade 5: Death related to AE. TEAEs were defined as any AE that occurs during the active phase of the study (between the start of the 3 month treatment period and 3 months after the end of study treatment). The worst intensity of TEAES at each grade are reported for all and for related TEAES. In the event of multiple occurrences of the same AEs being reported by the same subject, the maximum intensity and the most serious causality were reported.	From Day -42 up to Week 25.
PK Analysis of Glycofurol Excipients: Cmax.	Blood samples for determination of the excipients (N1-glycofurol and N2-glycofurol) serum concentrations were collected at Baseline (pre-dose), at 1, 2, 4, 6, 8, 12 and 24 hours post-dose and on Days 3 and 5. Mean serum N1-glycofurol and N2-glycofurol Cmax values were determined using non-compartmental analysis.	From Baseline (pre-dose) up to Day 5.
PK Analysis of Glycofurol Excipients: Tmax.	Blood samples for determination of the excipients (N1-glycofurol and N2-glycofurol) serum concentrations were collected at Baseline (pre-dose), at 1, 2, 4, 6, 8, 12 and 24 hours post-dose and on Days 3 and 5. Median serum N1-glycofurol and N2-glycofurol Tmax values were determined using non-compartmental analysis.	From Baseline (pre-dose) up to Day 5.
PK Analysis of Glycofurol Excipients: AUC0-∞ and Area Under the Serum Concentration Time Curve From Time 0 to Last Quantifiable Timepoint (AUC0-t).	Blood samples for determination of the excipients (N1-glycofurol and N2-glycofurol) serum concentrations were collected at Baseline (pre-dose), at 1, 2, 4, 6, 8, 12 and 24 hours post-dose and on Days 3 and 5. Mean serum N1-glycofurol and N2-glycofurol AUC0-∞ and AUC0-t values were determined using non-compartmental analysis. Only AUC0-∞ values fulfilling the accuracy determination rules were analysed.	From Baseline (pre-dose) up to Day 5.
PD Analysis: Mean Change From Baseline in Insulin-like Growth Factor 1 (IGF-1).	Blood samples were collected for the determination of IGF-1 in serum at Baseline (pre-dose), 6 hours post-dose and at Weeks 5, 9 and 13. Samples were also collected during follow-up at Weeks 17, 21 and 25 (or EW). Serum concentrations of IGF-1 were calculated using the Immulite 2000 Platform for all subjects in the safety population. The production of the reagent kits was stopped by the vendor during the study. The old reagent kits were used for Cohorts 1 and 2 until their expiry date and then the kits were switched to a new reagent and used for remaining subjects in Cohorts 2 and 3. Summary data for serum concentrations of IGF-1 were obtained using both methods (old and new reagent) and the mean change from Baseline at each time point is presented.	From Baseline (pre-dose) up to Week 25.
PD Analysis: Mean Change From Baseline in Growth Hormone (GH).	GH cycle assessments were performed by taking 5 samples in the morning (with a sample taken every 30 minutes for 2 hours) at Baseline (pre-dose), Week 5 and Week 13. Summary data for the mean of the 5 samplings of the GH cycle were generated and the mean change from Baseline at each time point is presented.	From Baseline (pre-dose) up to Week 13.
PD Analysis: Mean Change From Baseline in Free Triiodothyroxine (FT3) and Free Thyroxine (FT4).	Blood samples were collected for the determination of FT3 and FT4 in serum at Baseline (pre-dose) and at Weeks 2, 5, 13 and 25 (or EW). Summary data for serum concentrations of FT3 and FT4 were calculated and the mean change from Baseline at each time point is presented.	From Baseline (pre-dose) up to Week 25.
PD Analysis: Mean Change From Baseline in Thyroid Stimulating Hormone (TSH).	Blood samples were collected for the determination of TSH in serum at Baseline (pre-dose) and at Weeks 2, 5, 13 and 25 (or EW). Summary data for serum concentrations of TSH were calculated and the mean change from Baseline at each time point is presented.	From Baseline (pre-dose) up to Week 25.
PD Analysis: Mean Change From Baseline in Prolactin.	Blood samples were collected for the determination of prolactin in serum at Baseline (pre-dose) and at Weeks 2, 5, 13 and 25 (or EW). Summary data for serum concentration of prolactin were calculated and the mean change from Baseline at each time point is presented.	From Baseline (pre-dose) up to Week 25.
