Study to Assess the Safety, Tolerability, and Efficacy of Tipifarnib Plus Bortezomib in the Treatment of Acute Myeloid Leukemia (HEMOS AML 0106)

Phase II, Open-Label, Multi-centre, 2-part Study to Assess the Safety, Tolerability, and Efficacy of Tipifarnib Plus Bortezomib in the Treatment of Newly Diagnosed Acute Myeloid Leukemia (AML) Unfit for Conventional Chemotherapy ( >18 Years) or in Patients With Acute Myeloid Leukemia in First Relapse ( >60 Years)

This is one of the first studies of combination of Zarnestra plus Velcade in man. A primary objective of the study is therefore to assess the safety and tolerability of multiple doses of Zarnestra plus Velcade in patients with AML.

New treatments for patients that are untreatable with intensive chemotherapy aged de novo AML patients or post-relapse AML are urgently required since, at present, many of the drugs used for second line therapy are the same as those used for first induction and response rates are much lower.

• The following evidence suggests that Velcade plus Zarnestra can be an attractive therapeutic combination for: AML patients.
• Affymetrix gene profiling data showed expression of NFkB1 in all of 5 myeloid cell lines cell lines tested and 35% of over 250 patient samples ( data generated in collaboration with Sergio Ferrari and Pier Paolo Piccaluga unpublished results, our Institute and University of Modena,Italy)
• Preclinical evidence showed that AML cells in suspension culture were prevented to develop de novo drug resistance and mediated drug resistance.

In Part B additional patients with AML will be treated to further characterize the tolerability,biological effects, and clinical efficacy of the combination Velcade plus Zarnestra. Patients on treatment for AML will undergo regular bone marrow aspirates and biopsies to assess responses to treatment. This will facilitate frequent assessment of biological endpoints (reduction in expression and phosphorylation of IKKb kinase, and downstream markers of signalling along with apoptosis, survival, proliferation and cellular size and ploidy) will be made in an attempt to confirm that the desired biological activity has been achieved at the maximum tolerated dose.

Primary Outcome Measures

Outcome Measure	Time Frame
PART A: Assess the safety and tolerability of combined use of Zarnestra plus multiple ascending doses of Velcade in patients with de novo AML unfit for conventional chemotherapy (age >18 years) or in first or subsequent relapse ( >60 years).(COMPLETED)	August 2007
Part B.1: Assess the effect of Tipifarnib plus the defined in part A dose of Velcade in patients with de novo AML unfit for conventional chemotherapy (age >18 years) or in Patients in first or subsequent relapse ( >60 years) (COMPLETED)	December 2008
Part B.2: Evaluate the overall response (CR, PR, HI) of patients with a RASGRP1/APTX gene expression ratio > 10, identified as predictive of a good clinical response to tipifarnib in patients with de novo AML unfit for conventional chemotherapy.	June 2010
