VEGFR-3 expression profiling by histology to classify patient population for the selective VEGFR-3 inhbitor EVT801 (Section 41; Poster Board #25) - Mar 14, 2023 - Abstract #AACR2023AACR_2224; P1 This enables us selecting indications that might benefit from EVT801 as a monotherapy (e.g., clear cell renal cell carcinoma and soft tissue sarcomas) or in combination with standard of care. Accordingly, VEGFR-3 expression is retrospectively quantified during EVT801 clinical trial phase 1 trial and may be used to stratify patients in the future.

The studies conducted so far have provided a relatively wide range of drugs, which are at least well tolerated and demonstrated some efficacy in the randomized clinical trials. The comprehensive understanding of the molecular biology of gliomas promises to further improve the treatment outcomes of patients.

Preclinical, Journal: Combination of ribociclib with BET-bromodomain and PI3K/mTOR inhibitors for medulloblastoma treatment in vitro and in vivo. (Pubmed Central) - Nov 2, 2022 A reverse combination screen using the BET inhibitor JQ1 as anchor, revealed CDK4/6i as the most potentiating drugs...Despite in vitro synergy, combination of ribociclib with the PI3K/mTOR inhibitor paxalisib did not significantly improve the survival of G3 and SHH MB bearing mice compared to ribociclib alone...Importantly, in one untreated Group3 medulloblastoma model HD-MB03, the PI3K/AKT/MTORC1 gene set was enriched in vitro compared to in vivo suggesting that the pathway displayed increased activity in vitro. Our data illustrate the difficulty in translating in vitro findings in vivo.

Preclinical and case study examination of the combination of the CLPP agonist ONC201 with the PI3K/AKT inhibitor paxalisib for the treatment of diffuse midline glioma. (East Hall) - Sep 28, 2022 - Abstract #SNO2022SNO_88; P2 Compassionate access to this combination (n=2 patients; immediately post-RT and following re-RT) resulted in dramatic reductions in tumor volume, extending overall survival for the patient at diagnosis and the patient at progression (e.g., MR axial diagnosis scan = 1554 mm2, following twelve months on the combination, current tumor volume = 464 mm2 (~70% reduction), patient remains in progression free survival, 15 months since diagnosis). The clinical utility of our preclinical data is currently under investigation in the PNOC022 clinical trial (NCT05009992).

(Pubmed Central) - Sep 6, 2022 Further, the heart contractility, heart fibrosis, and survival were improved in response to the cardiac stressor isoprenaline when compared to vehicle-treated mice. Cummulatively, these data support mTORC1 activation as a therapeutic target in HD and consolidates NV-5297 as a promising drug candidate for treating central and peripheral HD phenotypes and, more generally, mTORC1-deficit related diseases.

Histone H3 K27M mediated regulation of cancer cell stemness and differentiation in diffuse intrinsic pontine glioma (DIPG) (Section 23) - Mar 9, 2022 - Abstract #AACR2022AACR_5915; This combination has produced an exquisite synergy in cells, which we will test in clinically-relevant DIPG models. Taken together, through these studies we have gained mechanistic insight into H3K27M mediated regulation of cancer cell stemness and differentiation in DIPG, which appears to be mediated by Wnt-dependent signaling of ALDH1A3 and provides rationale for exploring new therapeutic targets.
