This is a phase I study of a novel compound P1446A-05. Aim of this study is to identify the the recommended phase II dose of the drug and to determine the nature of adverse effects associated with the drug. P1446A-05 capsules will be given continuously (28 days in each 28 day cycle) to patients suffering from advanced malignancies with no effective treatment available. The dose of the study agent will be lower i.e. 75 mg per day for initial patients. If this dose is found safe, higher dose will be administered to next set of (three to six) patients. This will continued till the safest and best dose is identified. Treatment will be given for 4 cycles and continued further if found effective. Dose schedule may be modified to introduce treatment holiday,if frequent adverse effects are seen on continuous administration.

||An Open Label, Multicenter Phase I Study Of Selective Cyclin Dependent Kinase Inhibitor P1446A-05 In Subjects With Advanced Refractory Malignancies
Primary Outcome Measures:

Single arm of the study drug. This being a dose escalation study, patient will receive a dose depending on the stage of the trial.
P1446A-05 capsules will be given once daily for 28 days in each 28 day cycle for 4 such cycles. The starting dose, for first cohort will be 75 mg once daily. Subsequent cohorts of patients will receive higher doses till the recommended phase II dose is identified.

- Any other investigational drug within 1 month prior to day 1 of study drug administration or not recovered (to ≤grade 1) from adverse effects of the investigational agent received prior to this period.
- History of allergic reactions attributed to compounds of similar chemical structure to P1446A-05.
- On immunosuppressive therapy.
- History of unstable angina or myocardial infarction or stroke within 6 months prior to Day 1 of study drug administration.
- Uncontrolled inter-current illness including, but not limited to active infection, symptomatic congestive heart failure, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
- Known to be suffering from infection with HIV, Tuberculosis, Hepatitis C or Hepatitis B.
- Pregnant or lactating 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 (two methods of contraception, including at least one barrier method, - i.e. : hormonal and a barrier method of birth control or abstinence) prior to study entry (after signing the informed consent document), during the duration of study participation and for at least 4 weeks after withdrawal from the study drug, unless they are surgically sterilised.
- Any condition, including laboratory abnormalities, that in the opinion of the investigator places the subject at an unacceptable risk or deems the subject not suitable for participation in the study.
