Wirklich Berichterstattung zu den vorgestellten Studien von der esmo, mal schauen wie die Experten die Daten final einordnen...
Um 11:15 kommt für biontech die letzte mit bnt113, der abstrakt dazu liest sich schonmal sehr gut:
Results From 05/2017 to 01/2023, 17 patients with HPV16+ HNSCC participated in Arm 1A. 76% were male (n=13) with median age 63. Arm 1B enrolled 13 patients with anal (38%, n=5), HNSCC (23%, n=3), cervical (15%, n=2), other (23%, n=3) after failure of prior therapies; 77% were female (n=10) with median age 58. 19 (63%) received all 8 doses. Although no DLTs were reported, 2 patients in Arm 1A met individual MTDs. Grade≥1 ADRs ≤1wk after any vaccination/Grade≥3 ADRs ≤90d after last vaccination were experienced in 90% (n=26)/24% (n=7) patients among the 29 dosed. Disease control was seen in 5/7 patients (71%, 95% CI 29% – 96%) in Arm 1B with post-treatment tumour scans. Of evaluable patients, 70% mounted cellular immune responses against E6/7 as measured ex vivo by IFNγ ELISpot : 11/13 patients Arm 1A and 3/7 in Arm 1B. Anti-E7 IgG-Ab responses were detected in 8/15 (Arm 1A) and 5/9 (Arm 1B) patients. De novo T cell responses against E7 epitopes were found ex-vivo at a dose of 72.8 μg (Arm 1A Cohort II and Arm 1B); CD4+ and CD8+ E7-reactive T cell clones, were detected after in-vitro stimulation also at 29 μg (5/6 patients, Arm 1A). Vaccine-induced E7/E6-specific T cells reached up to 4.9% of CD8 T cells in circulation and were tracked by multimers in several patients longitudinally. TCR-seq (TIL and blood analysis) and TME characterisation data will be presented.
Conclusions BNT113 was overall well tolerated. Vaccine-induced immune responses were seen in the majority of patients in the adjuvant setting and in the presence of advanced disease. |
