Summary

This study will evaluate the preliminary safety, pharmacokinetics, and anti-tumor activity of pasireotide s.c. in patients with metastatic melanoma or metastatic Merkel cell carcinoma. The study consists of three phases: screening, intra-patient dose-escalation, and follow-up phases.

In the screening phase patient will be informed of all aspects of the study and sign informed consent forms and then be screened for study eligibility.

During the intra-patient dose escalation phase, 18 patients will be treated with pasireotide s.c. 300 μg t.i.d. for 2 weeks. If there are no unacceptable AEs, defined as drug-related clinically meaningful, uncontrolled grade 3 or any grade 4 toxicities, patients will be dose escalated to 600 μg t.i.d. for 2 more weeks, then 900 μg t.i.d. for 2 weeks and then 1200 μg for 2 weeks provided that there are no unacceptable AEs. Each patient will be in the dose escalation phase for a maximum of 8 weeks.

At end of the intra-patient dose escalation phase, patients will be allowed to switch to 80 mg pasireotide LAR i.m. q 28 d (or a lower dose in case of toxicity) for an additional 6 months or until disease progression, or unacceptable AEs, or patient withdraws consent. In addition, all patients will keep their pasireotide s.c. t.i.d. treatment (same dose as that at the end of the 8-week dose escalation phase) during the first 2 weeks of the LAR follow-up phase, except on the day receiving the first LAR dose because of an anticipated initial burst of drug release.

Conditions

  • Metastatic Melanoma and Merkel Cell Carcinoma

Interventions

DRUG

Pasireotide sub-cutaneous formulation

Pasireotide, will be administered to all patients by s.c. injection, beginning with a dose of 300 μg administered three times daily (t.i.d.) for 2 weeks. If no pasireotide-related clinically meaningful/uncontrolled grade 3 or grade 4 adverse events occur the dose will be administered to all patients at an increased dose of 600 μg t.i.d. for 2 weeks, followed by 2 weeks of 900 μg t.i.d. and followed by 2 weeks of 1200 μg t.i.d. After the 8 weeks period, patients will be kept on treatment drug (highest dose without clinically meaningful/uncontrolled AEs) , switched to the corresponding pasireotide LAR dose and followed up for an extra 6 months.

DRUG

Pasireotide lon acting release formulation

At the start of the follow-up phase patients will be switched to pasireotide LAR administered intramuscularly every 28 days by using the following conversion algorithm so that the steady state PK exposure (Cmax and Ctrough) of pasireotide will be maintained: 300 μg s.c. t.i.d. fi 20mg LAR i.m. q 28 days 600 μg s.c. t.i.d. fi 40 mg LAR i.m. q 28 days 900 μg s.c. t.i.d. fi 60 mg LAR i.m. q 28 days 1200 μg s.c. t.id. fi 80 mg LAR i.m. q 28 days In addition, all patients will keep the treatment with pasireotide s.c. during the first 2 weeks of the LAR phase. The use of s.c. dosing during the initial 2 week period following the first LAR dose provides an appropriate level of medication during the LAR nadir.
