Study of Pasireotide in Patients With Rare Tumors of Neuroendocrine Origin

Percentage of Responders at Month 6 - Pooled Pancreatic NETs (PNETs)

Time frame · 6 months

The primary efficacy endpoint was defined as the percentage of responders at Month 6 among pooled PNET patients (insulinoma, gastrinoma, VIPoma, and glucagonoma). A responder was defined as a patient who either attained normalization or had a greater than 50% reduction from baseline of the level of the primary biochemical tumor marker at Month 6 (M6). Four insulinoma pts were excluded from analysis because of unavailability of normal ranges for the associated primary biochemical tumor marker (insulin-to-glucose ratio). One patient with VIPoma with a normal baseline was also excluded. As a result, only 20 out of 25 patients with PNET were included in the assessment of the primary endpoint, which was less than the planned sample size of 34. Therefore, the primary objective could not be assessed with sufficient power. Patients with missing Month 6 assessment were considered as non-responders. Responder analyses are reported only for indications with minimum of 6 patients.

Percentage of Responders at Month 6 - Individual NETs

Time frame · 6 months

Percentage of responders for each of the 10 NET indications considered in the study. Responder analyses were performed for an indication only if there were at least 6 patients in the efficacy analyzable set. For all other individual indications, the numbers of patients in the efficacy analyzable sets were less than 6 and therefore no responder analyses were carried out for these indications.

Percentage of Responders With Probability of Success at Month 6 - Individual NETs

Time frame · 6 months

Percentage of responders for each of the 10 NET indications considered in the study. Responder analyses were performed for an indication only if there were at least 6 patients in the efficacy analyzable set. For all other individual indications, the numbers of patients in the efficacy analyzable sets were less than 6 and therefore no responder analyses were carried out for these indications. The probability of success was a chance that the true responder rate was greater than 15%) for the indications gastrinoma, prolactinoma, and Nelson's syndrome.

PNETs: Number of Patients Attaining Normalization or a More Than 50% Reduction in Primary Biochemical Tumor Marker

Time frame · Baseline, month 6

Specific primary biochemical tumor markers were used to assess the efficacy of pasireotide in PNETs. A Month 6 responder was defined as the patients who either attained normalization or greater than 50% reduction from baseline in the level of the primary biochemical tumor marker at Month 6. One gastrinoma patient had a missing primary tumor marker value at Month 6, but had a Month 5 assessment done on Day 141, which fell within the allowed window period for Month 6.

PiNETs: Number of Patients Attaining Normalization or a More Than 50% Reduction in Primary Biochemical Tumor Marker

Time frame · Baseline, month 6

Specific primary biochemical tumor markers were used to assess the efficacy of pasireotide in PNETs. A Month 6 responder was defined as the patients who either attained normalization or greater than 50% reduction from baseline in the level of the primary biochemical tumor marker at Month 6.

Nelson's Syndrome: Number of Patients Attaining Normalization or a More Than 50% Reduction in Primary Biochemical Tumor Marker

Time frame · Baseline, month 6

Six patients with Nelson's syndrome met the responder's criteria of attaining normalization or a reduction of more than 50% in primary tumor marker at Month 6.
