SCIO-469: Open-Label Study for Patients With Myelodysplastic Syndromes.

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine the safety and effectiveness of oral SCIO-469 in patients with myelodysplastic syndromes. SCIO-469 belongs to a new class of treatments that inhibit expression and activity of cytokines that play a role in the progression of MDS.

Detailed Description
-----------------
SCIO-469 belongs to a new class of treatment that inhibits p38 MAP kinase. p38 MAPK activation controls the production of TNF-a, VEGF, and IL-1b. As an inhibitor of p38 MAPK, SCIO-469 blocks the synthesis of these molecules, as well as TNF-a activity. This randomized, open-label, modified dose-ascension study is designed to assess the safety, tolerability, and efficacy of oral SCIO-469 in the treatment of patients with MDS. This patient group was selected because of the inhibitory effect of SCIO-469 on the expression and activity of cytokines that play a role in the progression of MDS. The treatment arms will be 30, 60 , 90, or 120 mg tid with 15 subjects per arm (total of 60 subjects) and each arm may expand to 25 subjects per arm (maximum total of 100 subjects). Initially, subjects will be randomly assigned to one of the lowest two treatment arms (30 mg tid or 60 mg tid). When 6 subjects per arm (at least 12 subjects total) have received study drug for at least 4 weeks, predefined criteria will be used to determine whether to open randomization into the third arm (i.e., 90 mg tid). The criteria will be based on the number of subjects who have had to suspend study drug due to drug-related toxicity. The 120-mg tid arm will be open for enrollment after 15 subjects have been enrolled into each of the first three treatment arms; the decision to open enrollment will be similar to the criteria used to open the third arm. Subjects will be evaluated at least monthly for safety and some efficacy measurements (AE reporting, safety labs and vitals). Subjects will receive study drug for 16 weeks. Subjects who demonstrate hematologic improvement (erythroid, platelet, or neutrophil response by IWG criteria) at week 16 will be eligible to continue treatment at the same dose of study drug for up to 36 additional weeks (52 weeks of total drug exposure). Subjects who do not meet the IWG criteria for hematologic improvement at week 16 but who, in the judgment of the investigator, experience clinical benefit may also receive up to 36 additional weeks of treatment. The same judgments for treatment extensions of additional 26 weeks in responding subjects will be made at 52 weeks and 78 weeks; maximum total drug exposure will be 104 weeks. All subjects will be followed for 4 weeks after the last study drug treatment for safety assessments or until resolution of Grade 3 or greater treatment-related toxicity as defined by NCI CTCAE (v. 3.0). Oral SCIO-469 given for 16 weeks to patients with MDS. Subjects will receive a total daily dose of SCIO-469 of 90 mg, 180 mg, 270 mg, or 360 mg. The treatment arms will be 30-mg tablet tid, 60-mg tablet tid, 90-mg tablet tid, or 120 mg (i.e., two 60-mg tablets) tid with 15 subjects per arm (total of 60 subjects). Responding subjects may dose for up to 104 weeks total drug exposure.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Major or Minor Erythroid Response (Hematological Improvement - Erythroid [HI-E]) | Improvement in Erythroid (HI-E) lineage will be assessed as per International Working Group (IWG) criteria. HI-E major response is defined as greater than 2.0 gram per deciliter g/dL increase in hemoglobin for red blood cell (RBC) transfusion-dependent participants, transfusion independence. HI-E minor response is defined as 1.0 to 2.0 g/dL increase in hemoglobin for RBC transfusion-dependent participants and 50 percent decrease in transfusion requirements. | Week 16 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Achieving Major or Minor Neutrophil Response (HI-N) | Major or minor neutrophils response is Hematologic Improvement in Neutrophil (HI-N) lineage. It will be assessed as per International Working Group (IWG) criteria. HI-N major response is defined as for participants with pre-treatment Absolute Neutrophil Count (ANC) less than 1500 per micro (l), at least 100 percent increase or an absolute increase more than 500 per micro l, whichever is greater. HI-N minor response defined as for participants with pre-treatment ANC less than 1500 per micro l, ANC increase of at least 100 percent, but with absolute increase less than 500 per micro l. | Week 16 | 
| Percentage of Participants Achieving Major or Minor Platelet Response (HI-P) | Major or minor neutrophils response is Hematologic Improvement in Platelets (HI-P) lineage. It will be assessed as per International Working Group (IWG) criteria. HI-P major response is defined as for participants with pre-treatment platelet count less than 100,000 per micro liter (l ), an absolute increase of 30,000 micro l or more. HI-P minor response defined as for participants with pre-treatment platelet count less than 100,000 per micro l, a 50 percent or more increase in platelet count with net increase greater than 10,000 per micro l but less than 30,000 per micro l. | Week 16 | 
| Percentage of Participants Achieving Complete or Partial Bone Marrow (BM) Response | Bone marrow response will be assessed as per the IWG criteria. Bone marrow response categories are: complete remission and partial remission. Complete remission is defined as normal bone marrow morphology (less than 5 percent myeloblasts with no cytologic dysplasia). Partial remission is defined as (must last at least 8 weeks) blasts decreased by 50 percent or more over pre-treatment, or a less advanced Myelodysplastic syndrome (MDS) French-American and British (FAB) classification than pre-treatment | Week 16 | 
| Percentage of Participants Achieving Major or Minor Cytogenetic Response | Cytogenetic response will be assessed as per IWG criteria. Major response is defined as no detectable cytogenetic abnormality, if pre-existing abnormality was present. Minor response is defined as greater than percent 50 reductions in abnormal metaphases. | Week 16 |
