Brief summary
Study evaluating SOM230 in patients with metastatic carcinoid tumors
Interventions
Open label. Patients received starting dose of 300 µg of study drug subcutaneously (s.c.) twice (total of 600 µg ) daily for three days, which could be increased in 150 µg increments up to 900 µg twice daily (total 1800 µg daily) if control of symptoms was not achieved. Prior sponsor agreement was required for a higher dose. A dose of 2400 µg/day was the maximum allowed. Dose reductions of 300 µg/day were allowed at any time if unacceptable toxicity occurred.

| Symptom Control (Diarrhea/Flushing) Using a Patient Symptom Diary | 15 days | Complete Symptom Control: an average of ≤ 3 bowel movements per day for at least 15 consecutive days, with no more than 3 episodes on any given day, and no episodes of flushing over the time interval being studied. Partial Symptom Control: an average of \< 4 bowel movements per day for at least 15 consecutive days, with no more than 6 episodes per given day, and an average of fewer than 2 daily flushing episodes over the same given time interval. Treatment failure: Failure to obtain partial or complete treatment success over a consecutive 15-day period at a constant dose level. |

| The Number of Patients (Participants) With Overall Tumor Response | At least 15 days | The disappearance of all lesions was considered a complete response and at least a 30% decrease in the diameter of lesions was considered a partial response (PR). Progressive disease (PD) required a 20% increase in the sum of the diameters of lesions and changes that did not qualify for PR or PD were considered stable disease. Progression not documented was defined as unknown. No more than a 10% increase in biochemical values, and no clinical signs of DP with complete or adequate control over symptoms were defined as complete treatment success and partial treatment success, respectively. |
| The Overall Safety and Tolerability of Pasireotide | At least 15 days | Safety assessments consisted of recording all AEs and serious adverse events (SAEs), the regular monitoring of hematology, blood chemistry, vital signs, physical condition and body weight. |

The disappearance of all lesions was considered a complete response and at least a 30% decrease in the diameter of lesions was considered a partial response (PR).

The Overall Safety and Tolerability of Pasireotide
Safety assessments consisted of recording all AEs and serious adverse events (SAEs), the regular monitoring of hematology, blood chemistry, vital signs, physical condition and body weight.
Time frame: At least 15 days
Population: The safety population consisted of all patients who received study drug (i.e. who started the pasireotide injections) and was thus identical to the Intent to treat (ITT) population.
