Phase II Trial Of ZK-EPO (ZK 219477) (Sagopilone) In Metastatic Melanoma

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to find out how effective an investigational drug named ZK-Epo is against melanoma. Although ZK-Epo has been studied in the treatment of cancer, it is not approved for use in treating melanoma. This research is being done because currently there are only a limited number of treatment options for patients who have melanoma that has spread to distant organs. We expect each patient to be in this study for at least 2 cycles. One cycle lasts for 21 days. If their tumor does not grow after 2 cycles and they do not have any major side-effects, they may receive up to 6 cycles of ZK-Epo. If after they have received 6 cycles of ZK-Epo and their doctor determines that the tumor is continuing to shrink, they will continue treatment with ZK-Epo. The number of treatments the patient receives after 6 cycles will depend upon when their doctor feels there has been maximum tumor response (tumor shrinkage). Two treatments will be given beyond what their doctor considers the point of maximum shrinkage. We estimate that they will spend anywhere from 1 1/2 months to 5 months taking part in this study.

Detailed Description
-----------------
Each Cycle is a 21 day period. On the first day of each cycle each patient will receive the study drug, ZK-Epo, through an IV infusion over a 3 hour period. Patients will receive the study drug only once every 21 day period. At the start of each cycle patients will have the following tests: Patients will be asked questions about their medical history and health and undergo a complete physical exam. Blood tests will be done to check blood cell count and organ functions (about 1 tablespoon of blood will be taken). Performance status tests (will determine patient's ability to perform everyday functions). A nurse or doctor will ask patients how they are feeling and about any side effects that patients may be having. Pre Study Visit: Blood test called lactate dehydrogenase (LDH) to check organ function. Prothrombin time (PT) and an a partial thromboplastin time (PTT) to see if the patient's blood clots normally. Electrocardiogram (EKG) (to measure the electrical function of patient's heart). Pregnancy Test (IF APPLICABLE a woman of child bearing age). Optional Tumor Biopsy (If indicated by patient's physician). Cycle 1, Day 1: Pharmacokinetics: special blood tests to measure the drug levels, LDH Cycle 1, Day 2 & 8: Pharmacokinetics Cycle 1, Day 15: EKG Cycle 2, DAY 1: LDH Cycle 3, DAY 1: LDH, PT & activated partial thromboplastin time (aPTT) Cycle 4, 5, & 6, and all subsequent cycles, Day 1: LDH During the first cycle only patients will also need to come for a study visit on day 8 and 15. During these two visits, blood tests will be done again to check blood cell count and organ functions. Patients will also be asked how they are feeling and about any side effects that they may be having. Computed tomography (CT) scans or a magnetic resonance imaging (MRI) will be done after every 2 cycles that each patient completes on the study. These will be done to help the doctor re-evaluate each patient's disease. Patients may have some additional blood tests done if they are among the first 10 patients taking part in this study. In this case they will have 9 samples of blood (each about a teaspoonful) drawn from them at specifically timed intervals (at 30 minutes before the start and at 30 minutes, 2 hour 55 minutes, 3 hour 10 minutes, 3 hour 30 minutes, 5 hour, 8 hour, 27 hour (+/- 1 hour) and 168 hour (+/- 4 hours) after the start of the ZK-Epo infusion) so that we can better understand the level of this drug in the body and its metabolism in people.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Chemotherapy - ZK-EPO<br>ZK-EPO (ZK 219477) (Sagopilone), 16 mg/m^2, was administered intravenously over 3-hours every 21 days until progression or unacceptable toxicity. | Drug: ZK-EPO<br>* Participants were treated with 16 mg/m^2 of ZK-EPO (EpothiloneZK) (Sagopilone) administered as a single 3 hour intravenous infusion every 21 days. Prior to each treatment, participants were premedicated with either granisetron or ondansetron and additional anti-emetics if needed. Chemotherapy was continued until disease progression, withdrawal of consent, or for unacceptable treatment-associated toxicity.<br>* Other names: Sagopilone;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Response Rate (RR) | Objective tumor response according to Response Evaluation Criteria In Solid Tumors (RECIST). Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Stable Disease (SD): Stable disease is measured from the start of the treatment until the criteria for progression are met, taking as reference the smallest measurements recorded since the treatment started, including the baseline measurements. Progressive Disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). | Up to 5 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Median Progression Free Survival (PFS) | PFS: the duration of time from start of treatment to time of progression or death, whichever occurs first. Progressive Disease (PD)according to modified Response Evaluation Criteria in Solid Tumors (RECIST) Criteria: At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). | Up to 5 years | 
| Median Overall Survival (OS) | Median OS: the time (expressed in months or years) when half the patients are expected to be alive. | Up to 5 years | 
| Occurrence of Attributable Serious Adverse Events (SAEs) | Number of participants with Grade 3 or higher adverse events, attributable to treatment with sagopilone. | Up to 5 years |
