The abstract of highest current interest is the one on which Incyte is working with Novartis. (a Phase III trial).
Supergen has two abstracts.. I was kinda surprised (link) and phase I clinical study of an oral inhibitor
Ok, more information will be added during the evening. Have to do AH trading now..ciao
Vical has posted a very clear abstract on what they have done/found/plan to do.
Background: Allovectin is a plasmid-based immunotherapy expressing HLA-B7 and β2 microglobulin genes designed to stimulate both local and systemic anti-tumor responses. In a phase II single-arm study, VCL-1005-208 (2 mg, intralesional injection in 127 subjects), overall response rate (ORR) was 11.8% and median overall survival (OS) was 18.8 months. Median duration of response was 13.8 months and all responses were durable (> 6 months). A subsequent phase III trial (LX01-315) recently completed enrollment of 390 pts in more than 90 sites in 15 countries. Subjects in phase II with characteristics corresponding to those in this phase III study (chemonaïve with a single lesion injected) had an ORR that was 17% and median OS was 22.5 months. Methods: A time-dependent covariate (TDC) analysis with the Cox proportional hazards model (SAS/STAT PROC PHREG) was used to evaluate the relationship between a time-varying covariate (responder status) to survival in the phase II study. The Cox model analysis combines these results across times (one time point per death) to yield a single p-value for the prognostic significance of responder status. Results: In our analysis of the VCL-1005-208 data, each patient had a single covariate, responder status that permanently switched from 1 to 0 when a non-responder became a responder. The single covariate approach tested the hypothesis that responder status predicted survival. The resulting hazard ratio for the TDC was 4.13 (95% CI: 1.67-10.25, score test p-value=0.002), which is relatively large and highly significant. A simpler analysis, using responder status as if it were a baseline covariate, gave a hazard ratio of 4.82 (95% CI 1.95-11.89, p-value<0.001). The TDC analysis indicates that in a small, open-label phase II trial, responder status strongly predicted survival. Analysis of two other trials (using 10 mcg DNA), VCL-1005-205 (phase II) and VCL-1005-301 (phase III), showed similar results. Conclusions: In three Allovectin melanoma trials, response was a strongly significant predictor of survival and may serve as a marker of clinical benefit for this novel class of cancer immunotherapeutic agents.
