Brief summary
The Total duration of trial participation for each participant with post-bariatric hypoglycemia will be a maximum of 59 weeks, with the following duration of trial periods * 19 weeks for the Core Phase. It is composed of: * a Screening period: a maximum of 3 weeks * a Run-in period (no treatment): 4 weeks * a Blinded Treatment Phase: 12 weeks * 36 weeks Extension Phase = an open-label Treatment period * 4 weeks for the safety follow-up period (without any treatment).
Detailed description
Subjects with post-bariatric hypoglycemia will be screened for participation in this trial. Eligible patients will complete the rest of the Core phase by entering a run-in period of 4 weeks without any treatment. At the end of the run-in period, participants will be randomized to receive in a blinded manner either pasireotide 50 µg or pasireotide 100 µg or pasireotide 200 µg or Placebo subcutaneously three times a day (prior to each meal). Participants will blindly self-administer their treatment for a total of 12 weeks when the primary endpoint will be assessed. All participants completing the core phase will be offered to enter the extension phase. Participants will openly self-administer pasireotide 50 µg or pasireotide 100 µg or pasireotide 200 µg subcutaneously three times a day for a total of 36 weeks of treatment. There will be no more placebo during this extension phase of treatment. Dose changes/adjustments will be possible only during the extension phase and the decision to change the dose of pasireotide will be left to the investigator's judgment. All participants will come for a safety visit after discontinuation or completion of treatment.

| CORE PHASE: Assessessment of the effect of pasireotide s.c. on HRQoL (SF-36 score) | at 12 weeks | The 36-item Short Form Health Survey (SF-36) is a patient reported outcomes measure that consists of a 36-item self-report inventory. The SF-36 is an accepted metric for benchmarking indications against normative population-based statistics. It assesses health-related limitations in eight dimensions: physical functioning (PF), role limitations due to physical functioning (RP), bodily pain (BP), general health perceptions (GH), vitality (VT), social functioning (SF), role limitations due to emotional problems (RE), and mental health (MH). Two summary scores, the Physical Component Summary (PCS) and the Mental Component Summary (MCS), can be calculated from the eight-dimension scores (scale scores). |
| CORE PHASE: Assessessment of the effect of pasireotide s.c. on HRQoL (Dumping Score Questionnaire) | at 12 weeks | DSQ is a disease specific patient reported outcome (PRO) scale that was developed according to the FDA and EMEA guidelines. The questionnaire utilizes a 5-point Likert scale (0, none; 1, mild; 2, moderate; 3, severe; and 4, very severe) to ask a patient to evaluate the intensity of 10 early dumping symptoms (within 30 minutes (\<30 minutes) after food ingestion). In addition, the questionnaire also evaluates 5 late dumping symptoms (more than 1.5 hours (\>90 minutes) after food ingestion |
