Brief summary
The purpose of this randomized, multicenter, Phase III study was to compare the efficacy of paseriotide LAR and octreotide LAR in patients whose disease-related symptoms are inadequately controlled by currently available somatostatin analogues.
Interventions
Pasireotide LAR 60mg i.m. injection - patients may also receive pasireotide 600 µg s.c 3 times a day for symptom control as needed
Octreotide LAR 40mg i.m. depot injection - Patients may also receive octreotide 100 µg s.c. 3 times a day for symptom control as needed

| Improvement in Daily Mean Number of Flushing Episodes by Randomization Stratum and Treatment. | 6 months | Percent change from Baseline in total number of flushing episodes comprising Month 6 were compared between the two treatment groups using ANCOVA model with treatment as the main effect and symptom levels at Baseline (e.g. total number of flushing episodes at Baseline) and randomization stratum (D+F or F) as covariates. |

| Objective Tumor Response Rate Assessed by Investigator | Month 6 | Baseline evaluations were to include Triphasic CT scan or MRI of the abdomen. Triphasic CT or MRIs were to be read by same radiologist at each assessment, measuring the same target and non-target lesions and accounting for all lesions that were present at Baseline. All known disease was accounted for when assessing objective tumor status. Current objective tumor status was to be captured on Tumor Assessment CRF. Objective response rate was defined by RECIST criteria: Partial response (PR) must have ≥ 30% decrease in the sum of longest diameter of all target lesions, from the baseline sum. Complete response (CR) must have disappearance of all target and non-target lesions. For CR or PR, tumor measurements must be confirmed by 2nd assessments within 4 weeks. Progression = 20% increase in the sum of longest diameter of all target lesions, from smallest sum of longest diameter of all target lesions recorded at or after baseline; or a new lesion; or progression of non-target lesions. |
| Pasireotide LAR vs. Octreotide LAR on Disease Control Rate Based on RECIST Criteria | Month 6 | Disease control rate (DCR) is the proportion of patients with a best overall response of Complete Response (CR) or Partial Response (PR) or Stable Disease (SD). Complete Response (CR): Disappearance of all target lesions Partial Response (PR): At least a 30% decrease in the sum of the longest diameter of all target lesions, taking as reference the baseline sum of the longest diameters. Progressive Disease (PD): At least a 20% increase in the sum of the longest diameter of all measured target lesions, taking as reference the smallest sum of longest diameter of all target lesions recorded at or after baseline, or a new lesion; or progression of non-target lesions. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for PD. Unknown (UNK) Progression has not been documented and one or more target lesions have not been assessed or have been assessed using a different method than baseline. |

Participants by arm
| Arm | Count |
|---|---|
| Pasireotide LAR Patients assigned to pasireotide LAR will receive a 60 mg dose of pasireotide LAR i.m. depot injection once every 28 days (+/- 3 days) for 6 months at visits 2, 4, 5, 6, 7 and 8. A dose reduction to 40 mg is permitted if tolerability issues arise. In addition, after 24 hours of the first LAR injections the patients were permitted to use pasireotide s.c. formulation for breakthrough symptoms as needed. | 53 |
| Octreotide LAR Patients assigned to octreotide LAR will receive a 40mg dose of octreotide LAR i.m. depot injection once every 28 days (+/- 3 days) for 6 months at visits 2, 4, 5, 6, 7 and 8. A dose reduction to 30 mg is permitted if tolerability issues arise. Patients requiring a dose reduction are to return to the higher dose once the tolerability issue is resolved, if required for efficacy.
