Summary
This research study is a Phase I/II clinical trial. It is done to determine the best doses
that the investigational drug (P276-00) can be used safely. "Investigational" means that the
drug is still being studied and that research doctors are trying to find out more
information about it such as; the safest dose to use, the side effects it may cause and if
it is effective for treating relapsed/refractory multiple myeloma.
A majority of multiple myeloma patients overexpress a protein that plays a role in
regulating the body's cell cycle called Cyclin D1. The study drug P276-00 is a Cyclin D1
inhibitor under investigation in the treatment of solid tumors. The researchers therefore
believe that Cyclin D1 should be studied as a therapeutic target in myeloma. In this
research study, we are looking for the highest dose of P276-00 that can be given safely and
to see how well it works
Clinical Details
Official title: An Open Label, Multicenter Phase I Study To Evaluate Safety and Efficacy of P276-00 in Subjects With Relapsed and Relapsed/Refractory Multiple Myeloma
Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Primary outcome: maximum tolerated dose (MTD) in subjects with relapsed and relapsed/refractory Multiple Myeloma (MM)
Secondary outcome: clinical response of P276-00 in subjects with relapsed and relapsed/refractory MM 2. Exploratory pharmacogenomic analysis of serum and molecular markers associated with P276-00 use in the study population
Detailed description:
The pre clinical data demonstrated that P276-00 is a selective Cdk4-D1 and Cdk1-B inhibitor
with potent cytotoxic effects against MM cells including sensitive (MM1. S, RPMI 8226, OPM1,
OPM2) and resistant (MM1. R, Dox-40, LR5) to conventional chemotherapy as well as in mouse
xenograft models. The IC50 for this effect is between 300-1000 nM in vitro, and potential
doses to be evaluated in the clinical study can achieve these concentrations. This evidence
supports a rationale for evaluating the effects of P276-000 in patients with
relapsed/refractory MM in order to determine safety and tolerability as well as
pharmacokinetics and potential efficacy. The current study design allows for adequate
assessment of patient safety in terms of the potential adverse effects of P276-00.

biological agents like G-CSF in the 2 weeks prior to day 1 of study drug
administration and have not recovered completely from the side effects of the earlier
investigational agent 2. Subjects having received any other investigational agents
within 2 weeks prior to the date of enrolment 3. History of allergic reactions
attributed to compounds of similar chemical composition to P276-00 4. Subjects with a
