SU011248 in Patients With Metastatic Mucosal or Acral/Lentiginous Melanoma

Phase 2

Completed

• Conditions: Mucosal Lentiginous Melanoma; Acral Lentiginous Malignant Melanoma
• Interventions: Drug: Sunitinib

• Registration Number: NCT00577382
• Lead Sponsor: Dana-Farber Cancer Institute

Brief Summary

The purpose of this study is to evaluate how effective Sunitinib works in treating acral lentiginous and mucosal melanoma which has spread beyond the local region. Suninitib is a protein-tyrosine kinase inhibitor and acts as a c-kit inhibitor drug. It is believed to work by blocking signals on certain cancer cells which allow the malignant cells to multiply and spread due to a change in the genetic make up of the cancer cell.

Detailed Description

OBJECTIVES:

Primary

* To determine the proportion of participants with metastatic mucosal or acral/lentiginous melanoma who are alive and without disease progression at two months after beginning treatment with sunitinib.

* To determine the best overall response rate.

Secondary

* To determine the time to progression and overall survival.

* To correlate c-kit mutational status with response to therapy.

* To evaluate the use of FDG-PET scanning in determining early biologic response to therapy.

* To assess amplification of c-kit status through quantitative PCR and/or FISH and other related molecular pathway targets.

Arm && Interventions

Group	Intervention	Description
Sunitinib	Sunitinib	Cohort A participants received 50 mg sunitinib orally daily for 4 weeks followed by a two-week break from treatment. These 6-week cycles would be repeated until progression or unacceptable toxicity up to 1 year. Cohort B participants received 37.5 mg sunitinib daily on a continuous basis until progression or unacceptable toxicity up to 1 year.

Primary Outcome Measures

Name	Time	Method
2-month Progression-free Survival Rate	Disease was evaluated radiologically at baseline and every 8 weeks on treatment; Treatment continued for 12 months unless disease progression or unacceptable toxicity. Relevant for this endpoint was disease status at 2 months.	2-month progression-free survival rate was defined as the proportion of patients absent death or progression based on Response Evaluation Criteria In Solid Tumors Criteria (RECIST) before 2 months. Per RECIST 1.0 criteria: progressive disease (PD) is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions.

Secondary Outcome Measures

Name	Time	Method
Best Overall Response Rate	Disease was evaluated radiologically at baseline and every 8 weeks on treatment. Mean treatment duration was 3 cycles (Cohort A/B mean 2/3 cycles). The range of treatment duration overall was 1-11 cycles.	The best overall response rate was defined as achieving partial response (PR) or complete response (CR) on treatment based on RECIST 1.0 criteria. Per RECIST 1.0 for target lesions, CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. To be assigned a status of CR or PR, changes in tumor measurements must be confirmed by repeat assessments performed no fewer than 4 weeks after the response criteria are first met. PR or better overall response assumes at a minimum incomplete response/stable disease (SD) for the evaluation of non-target lesions and absence of new lesions.
Overall Survival	Patients were followed long-term every 3 months until first progression, death or lost to follow-up. Median survival follow-up was 6.7 months (range 0.8-47.3 months; Cohort A/B median 7.7 m/ 6.2 m).	Overall survival (OS) is defined as the time from study entry to death or date last known alive.
Time to Progression	Disease was evaluated radiologically at baseline and every 8 weeks on treatment and long-term every 3 months until first progression, death or lost to follow-up. Mean treatment duration was 3 cycles (range 1-11; Cohort A/B mean 2/3 cycles).	Time to progression based on the Kaplan-Meier method is defined as the duration of time from study entry to documented disease progression (PD) requiring removal from the study. Per RECIST 1.0 criteria: progressive disease (PD) is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions.
