In the preclinical study, durable antitumor effect was achieved through combination treatment with Olvi-Vec and cisplatin in mouse model of PROC. Combination therapy of Olvi-Vec and platinum-doublet chemotherapy resulted in a clinically meaningful benefit in the VIRO-15 study, reversing the typical trend of deteriorating PFS, and with clinical reversal of platinum resistance. Olvi-Vec treatment can favorably modify the TME in OC and may explain the apparent reversal of platinum resistance following platinum rechallenge.Trial Registration:ClinicalTrials.gov Identifier: NCT02759588.

However, elevated expression of poliovirus receptor (PVR) and the immune checkpoint T-cell immunoreceptor with immunoglobulin and ITIM domain (TIGIT) on tumor-infiltrating leukocytes suggests a potential resistance mechanism to virotherapy. Combining rQNestin34.5 v.2 with TIGIT blockade enhances therapeutic efficacy compared to monotherapy, identifying IDH1-R132H as a potential predictive biomarker for oncolytic virotherapy response.
Acute promyelocytic leukemia (APML) is characterized by promyelocytic leukemia retinoic acid receptor alpha (PML-RARA) fusion gene resulting from at (15;17) translocation. While, TLC significantly decreased from baseline in high risk cases to last follow-up (24 × 109/L vs. 9 × 109/L; P = 0.016). Patients with APML can be successfully treated with a combination of ATO and ATRA.
DOC1021 was safe, feasibly integrated within SOC, and associated with more favorable outcomes in this challenging patient population. Patients who received observation rather than reoperation for worsening MRI contrast-enhancement exhibited superior survival, suggesting an immune-reactive tumor microenvironment manifesting as pseudo-progression. These data supported initiation of a randomized Phase II trial ( NCT06805305 ) for nGBM.
