Genta Announces Results of AGENDA Phase 3 Trial of Genasense in Patients with Advanced Melanoma

Company Expects to Continue Trial to Assess Overall Survival


BERKELEY HEIGHTS, N.J.--(BUSINESS WIRE)--Nov 16, 2009 - <!-- cpurl -->Genta <!-- /cpurl -->Incorporated (OTCBB:GETA) today announced preliminary results from AGENDA, the Company's Phase 3 trial of <!-- ppurl -->Genasense<!-- /ppurl -->® (oblimersen sodium) Injection in patients with advanced melanoma. AGENDA is a randomized, double-blind, placebo-controlled trial of <!-- ppurl -->dacarbazine<!-- /ppurl --> (DTIC) administered with or without Genasense® in patients who have not previously received chemotherapy. As defined in a prior randomized trial, AGENDA uses a biomarker to define patients who might maximally benefit from treatment. These results are scheduled for oral presentation today by Prof. Celeste Lebbé, Hôpital St. Louis, Paris, France at an international conference, “Molecular Targets and Cancer Therapeutics”, at 5 PM ET in Boston, MA. The “Targets Meeting” is jointly sponsored by the American Association for Cancer Research (AACR), the U.S. National Cancer Institute (NCI), and the European Organization for Research and Treatment of Cancer (EORTC).

Efficacy Analysis
Currently available efficacy endpoints from AGENDA are presented in the table below.













Overall response   17%   12%   -   0.19
Disease control   42%   36%   -   0.3
Progression-free survival, median   2.8 mos.   2.7 mos.   0.85   0.23


The results do not show a statistically significant benefit for the co-primary endpoint of progression-free survival, nor for secondary endpoints of overall response or disease-control. All observed differences in currently available endpoints numerically favor the group that received Genasense®.


Durable Response


According to the prespecified analysis plan, durable response – a secondary endpoint that measures the proportion of patients who achieved a complete or partial response that lasts ‰¥ 6 months – is too early to evaluate. At present, the relative proportions of patients who have already achieved a durable response, as well as the number of patients with a complete or partial response who are still pending their evaluation at 6 months, also numerically favor the Genasense treatment group.


Overall Survival


Overall survival – the other co-primary endpoint in AGENDA – is too early to evaluate, as prospectively specified. An analysis for futility, which was defined as ‰¥ 50% conditional power to observe a statistically significant benefit of Genasense under the prospectively assumed hazard ratio of 0.69 and alpha level of 0.05, was conducted for the co-primary endpoint of overall survival. AGENDA has passed this futility analysis, and the Independent Data Monitoring Committee for AGENDA has recommended to the Company that the trial continue to completion. Pending availability of sufficient funds, Genta's Board of Directors has indicated that the trial should continue until the analysis for overall survival can be conducted.


Based upon the Company's projection of expected event rates, Genta currently anticipates that this analysis could be conducted in the Second Half of 2010. The Company has notified all study investigators that the trial should continue, that the double-blind design must remain in place, and that all patients who are currently receiving treatment should continue to receive treatment as randomized per protocol.




The safety profile of Genasense in AGENDA was consistent with prior studies. Neutropenia and thrombocytopenia were the only Grade 3-4 adverse events (AE) that affected ‰¥ 5% of patients in the study. There were no substantial differences in clinically relevant consequences of these findings, specifically including febrile neutropenia or Grade 3-4 bleeding events.

Grade 3-4 Adverse Events     Genasense/DTIC






Neutropenia     29   8
Thrombocytopenia     24   6
Leukopenia     7   3
Lymphopenia     7   3
Adverse events leading to discontinuations or death on study were low and well-balanced, as shown in the table below.








AE leading to discontinuation     7   9
Treatment-related AE leading to discontinuation     2   1
AE with outcome of death     3   3
Treatment-related AE with outcome of death     0   0

Patient Characteristics


Relevant clinical characteristics of patients in the two treatment groups were well-balanced, as shown in the table below.


Demographic Factor     Genasense/DTIC






Age, median (years)     58   60
Gender (M/F): (%)     59/41   66/34
Disease site(s): (%)          
Skin, soft tissue, lymph nodes     25   24
Liver metastases     24   25
Other visceral metastases     51   52
Disease stage” (%)          
Distant metastases     95   97
Loco-regional     5   3

Conference Call

Genta management will discuss these results during a previously scheduled conference call and live audio webcast in association with today's release of Third Quarter 2009 earnings, which will take place today, Monday, November 16, 2009 at 8:00 AM ET.
