Oncolytic HSV rewires metabolism to promote antitumor immunity through reductive carboxylation and ferroptosis
(SNO 2024)
- P1/2 | "RNA-seq data obtained from pre- and post-G207 treated biopsies from phase-Ib study patients (NCT00028158) revealed enrichment in pathways related to citric acid cycle, oxidative phosphorylation, and glutamate metabolism...IDH mutant tumors that block reductive carboxylation were resistant to oHSV-induced ferroptotic cell death and did not benefit from oHSV-induced antitumor benefit. Together, this study presents avenues to enhance antitumor immunity by oHSV therapy."

The safety and accuracy of intratumoral catheter placement to infuse viral immunotherapies in children with malignant brain tumors: a multi-institutional study.
(PubMed, J Neurosurg Pediatr)
- P1, P1b | "Although instances of minor hemorrhage were encountered, they were clinically asymptomatic. One of 49 catheters required intervention for a CSF leak. Congruent with previous studies in the literature, the stereotactic placement of catheters in these pediatric tumor patients was accurate with approximately 95% of catheters having been adequately placed."

Elucidating cellular response to treatment with viral immunotherapies in pediatric high-grade glioma and medulloblastoma.
(PubMed, Transl Oncol)
- "RNA sequencing of control cells and cells treated for 8 and 24 h revealed that there were few shared differentially expressed (DE) genes between cells treated with PVSRIPO and G207: GCLM, LANCL2, and RBM3 were enriched whilst ADAMTS1 and VEGFA were depleted. Likewise, there were few shared DE genes enriched between medulloblastoma and high-grade glioma cell lines treated with G207: GPSM2, CHECK2, SEPTIN2, EIF4G2, GCLM, GDAP1, LANCL2, and PWP1. Treatment with G207 and PVSRIPO appear to cause disparate gene enrichment and depletion suggesting disparate molecular mechanisms in malignant pediatric brain tumors."

Oncolytic virotherapies for pediatric tumors.
(PubMed, Expert Opin Biol Ther)
- "We reviewed seven virus types that have been investigated in past or ongoing pediatric tumor clinical trials: adenovirus (AdV-tk, Celyvir, DNX-2401, VCN-01, Ad-TD-nsIL-12), herpes simplex virus (G207, HSV-1716), vaccinia (JX-594), reovirus (pelareorep), poliovirus (PVSRIPO), measles virus (MV-NIS), and Senecavirus A (SVV-001). However, the antitumor effects of OVT remain variable depending on tumor type and viral agent used. Although the widespread adoption of OVT faces many challenges, we are optimistic that OVT will play an important role alongside standard chemotherapy and radiotherapy for the treatment of malignant pediatric solid tumors in the future."

Intraventricular immunovirotherapy; a translational step forward.
(PubMed, Oncotarget)
- "A recent preclinical study has paved the way for clinical translation of intraventricular administration of oHSV by identifying and mitigating the toxicity associated with this route for therapeutic benefit in murine models of disseminated medulloblastoma. This work may ultimately allow for targeting of intractable disease and provides a feasible option for the repetitive dosing of clinically relevant immunovirotherapy, G207."

Stem Cell Collection with Daratumumab (DARA)-Based Regimens in Transplant-Eligible Newly Diagnosed Multiple Myeloma (NDMM) Patients (pts) in the Griffin and Master Studies

In GRIFFIN, among 207 (D-RVd, n=104; RVd, n=103) randomized pts, 91.3% (n=95) of D-RVd pts and 77.7% (n=80) of RVd pts underwent stem cell mobilization; of those mobilized, 98.9% (n=94) and 97.5% (n=78) underwent ASCT, respectively... The addition of DARA to proteasome inhibitor/immunomodulatory drug/dexamethasone-based induction therapy has a modest impact on stem cell mobilization, with a lower yield of stem cells and higher median number of days required for collection. Nonetheless, pts were able to undergo transplantation, and most pts collected sufficient stem cells for 2 transplants. Pts who received plerixafor by an upfront..."

Clinical advances in oncolytic virotherapy for pediatric brain tumors.
(PubMed, Pharmacol Ther)
- "While the majority of brain tumor clinical trials utilizing oncolytic virotherapy have been in adults, five viruses are being tested in pediatric brain tumor clinical trials: herpes simplex virus (G207), reovirus (pelareorep/Reolysin), measles virus (MV-NIS), poliovirus (PVSRIPO), and adenovirus (DNX-2401, AloCELYVIR). Herein, we review past and current pediatric immunovirotherapy brain tumor trials including the relevant preclinical and clinical research that contributed to their development. We describe mechanisms by which the viruses may overcome barriers in treating pediatric brain tumors, examine challenges associated with achieving effective, durable responses, highlight unique aspects and successes of the trials, and discuss future directions of immunovirotherapy research for the treatment of pediatric brain tumors."

Chromogenic In Situ Hybridization for High Risk Human Papillomavirus RNA in Fine Needle Aspiration Samples of Metastatic Oropharyngeal Squamous Cell Carcinoma
(USCAP 2022)
- " 60 FNAs positive for metastatic OPSCC were identified among 207 neck FNA reports, of which 39 (65%) corresponded to HPV-OPSCC, 14 (23.3%) to HPV-negative OPSCC, and 8 (13.3%) were OPSCC with unknown HPV status... HR-HPV RNA ISH is an HPV-specific test that does not require a cut-off and is interpreted as positive or negative. While current guidelines recommend p16 immunohistochemistry as the best initial test in surgical specimens, several studies have debated reliability of p16 staining in cytology, mainly for two reasons: 1) many samples are cystic and yield low cellularity, and 2) it has been difficult to establish a reproducible p16 positivity cut-off. Application of HPV-specific methods in cytology may return cost and time-efficient benefits in diagnosis and management of OPSCC and CUP."
