それは、この記事のタイトルにもなっている、
「Agenus 2013年第3期決算情報が公開された」
というものです。
以下に紹介しているのはHerpVに関する記述なのですが、Agenusが開発したQS-21などのアジュバント(ワクチンの活性剤)も結構良い評価を受けているようで(大手のGlaxoSmithKline(GSK)から資金援助をしてもらったことからも伺えるかと思いますが…)、資金的面での不安はとりあえず無さそうですね…。
以下の記事で私が気になるところは…、
The Phase 2 data are anticipated during the fourth quarter of 2013.
「Phase 2 のデータは、2013年の第4期になるものと期待されている」
というところで、今年中にはPhase 2はほぼ完了するということになりそうです…。
資金的な面、データの集まり具合、そして使われているアジュバントに対する高い評価などを総合してみれば、結構いけるのかもしれませんね!
今後に期待したいものです♫
Heat Shock Protein Platform (HSP): Recombinant Series HerpV
HerpV is a recombinant therapeutic vaccine candidate for the treatment of genital herpes, which is caused by the herpes simplex virus-2 (HSV-2). HerpV, one of the most clinically advanced HSV-2 therapeutic vaccine candidates in development, is currently in a Phase 2 randomized, double-blind, multicenter study. The Phase 2 data are anticipated during the fourth quarter of 2013. The vaccine is based on Agenus' HSP platform technology, and contains Agenus’ proprietary QS-21 Stimulon adjuvant.
HerpV consists of recombinant human heat shock protein-70 complexed with 32 distinct 35-mer synthetic peptides from the HSV-2 proteome. This broad spectrum of herpes antigens is intended to allow for more accurate immune targeting and surveillance, reducing the likelihood of immune escape. Further, the diversity of antigens in HerpV increases the chance of providing efficacy for a wide segment of the patient population.
In a four-arm, Phase 1 study, 35 HSV-2 seropositive patients received HerpV (designated in the study as AG-707 plus QS-21), AG-707, QS-21 alone, or placebo. Patients received three treatments at two-week intervals. The vaccine was generally well tolerated, with injection site pain as the most common reported adverse event. All patients who received HerpV and were evaluable for immune response showed a statistically significant CD4+ T cell response (100%; 7/7) to HSV-2 antigens as detected by IFNγ Elispot, and the majority of those patients demonstrated a CD8+ T cell response (75%; 6/8). This study was published in the scientific journal Vaccine.
