Efficacy Study Of P276-00 In Subjects Of Malignant Melanoma Positive For Cyclin D1 Expression

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate efficacy of P276-00 in subjects with advanced malignant melanoma positive for cyclin D1 expression

Detailed Description
-----------------
Currently, melanoma is the fifth most common cancer diagnosed in men and the seventh most common cancer diagnosed in women.Advanced melanoma has a very poor prognosis.For a vast majority of subjects with malignant melanoma, there are no effective therapies.Therefore, the development of effective therapies for this subject population remains a priority in oncology.In a limited study in melanomas, increased cyclin D1 protein expression, as was observed in 33% cases.P276-00 is a novel potent small molecule flavone derived Cyclin dependent kinase (Cdk) Cdk 4-D1, Cdk1-B and Cdk9-T inhibitor.P276-00 demonstrated significant and selective antiproliferative effect against melanoma cell lines.

Exclusion Criteria: Treatment with P276?00 or other cyclin dependent kinase (CDK) targeting agents anytime in the past History of allergic reactions attributed to compounds of chemical composition similar to P276?00 Subject who have had chemotherapy, immunotherapy or radiotherapy within 4 week prior to first dosing of study agent. For nitrosoureas, there shall be interval of at least six week from first dosing of study agent Subject who have not recovered from adverse events (AE ³ CTCAE Grade 2) due to agents administered more than 4 week earlier. Subject who had received any other investigational drug within 1 month prior to day 1 of study drug administration Prior malignancy (within the last 3 years) except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, in situ breast cancer, in situ prostate cancer or any other cancer for which the subject has been disease-free for at least 3 years Any medical condition (such as but not limited to severe/unstable angina, history of myocardial infarction, coronary/peripheral artery bypass graft, symptomatic congestive cardiac failure, cerebrovascular accident or transient ischemic attack, pulmonary embolism) or laboratory abnormality(ies) which might make it difficult for the subject to participate in the study, at the discretion of the Principal Investigator (PI)or co-PI Known human immunodeficiency virus (HIV) positivity or acquired immunodeficiency syndrome (AIDS) related illness QTc > 470 millisecond on 12 lead Electrocardiogram at screening Pregnant or nursing women Women of childbearing potential [defined as a sexually mature woman who has not undergone hysterectomy or who has not been naturally postmenopausal for at least 24 consecutive months (i.e. who has had menses any time in the preceding 24 consecutive months)] and men, not agreeing to use adequate contraception (e.g., hormonal or barrier method of birth control or abstinence) after signing an informed consent document (ICD), during the duration of study participation and for at least 4 week after withdrawal from the study, unless they are surgically sterilized -
