The presentation entitled "EO2401 peptide immunotherapy + nivolumab +/- bevacizumab in first recurrent glioblastoma: the phase 1/2 EOGBM1-18/ROSALIE study" was delivered by David Reardon, M.D., Professor of Medicine at Harvard Medical School and Clinical Director of the Center for Neuro-Oncology at Dana-Farber Cancer Institute.

"We are very pleased to present extensive data from the Phase 1/2 ROSALIE study of EO2401, our lead OncoMimics peptide-based immunotherapy, in glioblastoma," said Pierre Belichard, Chief Executive Officer of Enterome. "EO2401 continues to generate strong, durable, and target-specific immune responses associated with encouraging efficacy. Based on the promising results presented at SNO 2023, which include an 18-months survival rate of 43%, we now look forward to developing a registrational path for EO2401."

Prof. David Reardon, lead investigator of the study and presenting author, commented: "Recurrent glioblastoma is one of the most challenging cancers to treat. It is encouraging to see that the robust and durable immune response observed in a significant percentage of patients could translate into promising clinical outcome in the ROSALIE study. Our hope is now that the improvement in survival associated with the combination regimen of EO2401 with nivolumab and bevacizumab will convert into meaningful therapeutic benefit for patients with brain tumors in large scale studies."

Key highlights from the presentation delivered at SNO conference:

EO2401 in combination with nivolumab and bevacizumab, as administered to 26 patients with recurrent glioblastoma comprising Cohort 3 of the ROSALIE study, was well tolerated with a safety profile consistent with the profile of nivolumab and bevacizumab, with the addition of local administration site reaction.
The combination demonstrated encouraging results including a median survival of 14.5 months, median duration of response of 13.1 months, and median progression-free survival (PFS) of 5.5 months.
The survival rate of 57.4% and 43.1% was observed at 12 months and 18 months respectively.
EO2401/nivolumab generated fast, strong, and durable systemic immune responses against the targeted tumor-associated antigens IL13Rα2, BIRC5/survivin, and FOXM1.
In Cohort 3, 23 patients (92% of tested, 88% of total) had a specific CD8+ T cell response against EO2401 and all of those patients (100%) had CD8+ T cells cross-reactive with the targeted TAAs, i.e., recognizing IL13Rα2, BIRC5/survivin, and/or FOXM1.

"GBM needs better treatment options, and we are highly encouraged by the initial data from the NIH-supported ReSPECT-GBM Phase 2 trial of rhenium (186Re) obisbemeda in rGBM," said Marc H. Hedrick, M.D., M.B.A., President and Chief Executive Officer of Plus Therapeutics. "We believe the data presented at SNO suggests that rhenium (186Re) obisbemeda confers a survival benefit over published standard of care data and our own real world data assessments of propensity matched controls. Our 2024 focus will be onboarding additional clinical sites, completing Phase 2 enrollment, continuing the phase 1 trial to maximum tolerated dose, and planning next steps for the program."

"The interim ReSPECT-GBM Phase 2 data coupled with the novel imaging analyses reported at SNO further strengthens the compelling therapeutic rationale for the use of rhenium (186Re) obisbemeda on malignant gliomas," said Andrew J. Brenner, M.D., Ph.D., Professor of Medicine, Neurology, and Neurosurgery at The University of Texas Health Science Center at San Antonio and principal investigator of the ReSPECT-GBM clinical trial. "The Phase 2 clinical outcomes thus far, show effects consistent with the group of patients in the Phase 1 dose escalation trial that received both a therapeutic dose of radiation of greater than 100 Gy and tumor coverage of greater than 70%."

Key Highlights from the ReSPECT-GBM Phase 2 Trial

ReSPECT-GBM is an ongoing, first-in-human, open-label, Phase 1/2 study investigating dose escalation and other delivery parameters (i.e., number of catheters (1-5), infusion rates, drug volumes, and drug concentrations) to determine the maximum tolerated dose (MTD), maximum feasible dose (MFD), safety, and efficacy of rhenium (186Re) obisbemeda in recurrent adult glioma (IND 116117).

The primary objective of the Phase 2 study is to assess overall survival (OS) following rhenium (186Re) obisbemeda administration. As of November 14, 2023, 15 patients with rGBM have been treated with rhenium (186Re) obisbemeda at a dose of 22.3 mCi delivered directly to the tumor by Convection Enhanced Delivery (CED).


In 15 treated patients, mOS is 13 months (95% CI 5 months). Currently, 9 out of the 15 treated patients remain alive.


Median PFS is 11 months (95% CI 6-11 months).


The average percent of treated tumor across all 15 patients was 87.2% at 120 hours, with 13/15 patients receiving greater than or equal 70% tumor volume coverage by the drug and ≥100 Gy absorbed dose to the tumor.


Advanced longitudinal imaging analysis supports the observed efficacy signal of rhenium (186Re) obisbemeda.


Rhenium (186Re) obisbemeda continues to be generally safe and well tolerated, consistent with data accumulated in the Phase 1 trial.

"FDA approval of APHEXDA in September was a transformative event for the company, and our U.S. commercial team is now working with payers and providers to make this important innovation available to patients," said Philip Serlin, Chief Executive Officer of BioLineRx. "We were pleased that APHEXDA was recently added to the NCCN guidelines, and we believe that as centers adjust their protocols to include and gain experience with APHEXDA, transplant teams will gain a deep appreciation for the efficiencies that it can provide, and more importantly, the improved treatment journey patients experience as they navigate their essential transplant process.

"In addition, the company also closed its motixafortide licensing agreement covering the important Asia market. The agreement, which provided significant upfront funding, will first advance potential indications in the region for stem cell mobilization and pancreatic cancer, areas of high unmet need. We continue to evaluate additional commercial partnership opportunities in other markets.

"Lastly, exciting data were presented at AACR (Free AACR Whitepaper) from the single-arm pilot phase of the randomized Phase 2 combination clinical trial with motixafortide in first-line pancreatic cancer by the study’s lead investigator at Columbia University. The highly encouraging data triggered a change in the protocol, from a small, single-arm study to a much larger randomized study. This study, as well as the enrolling Phase 1 study evaluating motixafortide for stem cell mobilization in patients with sickle cell disease seeking gene therapy, highlight the potential versatility of motixafortide and the tremendous progress we are making to realize the full promise of this novel molecule for patients around the world," Mr. Serlin concluded.

Third Quarter 2023 Financial Results

Research and development expenses for the three months ended September 30, 2023 were $2.7 million, a decrease of $1.6 million, or 37.6%, compared to $4.3 million for the three months ended September 30, 2022. The decrease resulted primarily from lower expenses associated with NDA supporting activities related to motixafortide as well as lower expenses associated with the completed AGI-134 clinical trial.

Sales and marketing expenses for the three months ended September 30, 2023 were $8.1 million, an increase of $6.8 million, or 517.4% compared to $1.3 million for the three months ended September 30, 2022. The increase resulted primarily from the ramp-up of pre-commercialization activities related to motixafortide

General and administrative expenses for the three months ended September 30, 2023 were $1.5 million, an increase of $0.1 million, or 7.7% compared to $1.4 million for the three months ended September 30, 2022. The increase resulted from small increases in a number of individual G&A expenses

Non-operating expenses for the three months ended September 30, 2023 were $3.1 million, an increase of $3.5 million, compared to non-operating income of $0.4 million for the three months ended September 30, 2022. The increase relates primarily to the revaluation of outstanding warrants resulting from an increase in the company’s share price during the 2023 period

Net loss for the three months ended September 30, 2023 was $16.0 million, compared to $6.8 million for the three months ended September 30, 2022. Net loss for the nine months ended September 30, 2023 amounted to $46.7 million, compared to $19.2 million for the nine months ended September 30, 2022. The increases in net loss for both the three- and nine-month periods in 2023 were primarily due to the significant non-operating expenses (which were also non-cash) related to revaluation of outstanding warrants, as well as the significant increases in sales and marketing expenses related to pre-commercialization and commercialization activities, which were partially offset by a decrease in research and development expenses

As of September 30, 2023, we held $26.0 million of cash, cash equivalents and short-term bank deposits. We anticipate that this amount, as well as the consideration from the exclusive license agreement and the securities purchase agreement of $29.6 million that was received in October 2023, will be sufficient to fund operations, as currently planned, into 2025

This is the third cancer drug in the last five years to reach market approval that has been discovered and developed under, or subsequent to, an Astex drug discovery collaboration. In addition to Truqap, Astex’s other partnered programs that have been highly successful in translating research into new cancer medicines include Novartis’ Kisqali (ribociclib) and Janssen’s BALVERSA (erdafitinib).

Truqap is a first-in-class oral targeted inhibitor of the cancer-driving protein AKT, also known as PKB. AKT is an enzyme that plays a key role in the PI3K/AKT tumor cell survival pathway, and dysregulation of this pathway leads to tumor resistance to a number of important anti-cancer medicines. Truqap was discovered by AstraZeneca following an earlier drug discovery research collaboration between Astex, The Institute of Cancer Research, London, and Cancer Research Technology (CRT; now Cancer Research Horizons) that was signed in 2003. As part of that earlier foundational research, Astex and The Institute of Cancer Research (ICR) used the 3D X-ray crystal structure of the AKT protein target to identify small molecule modulators of AKT activity using an approach known as fragment-based drug discovery. In 2005 a series of prototype drug compounds discovered by Astex and the ICR was shown to have very promising activity against a range of human tumors grown in mice and was licensed to AstraZeneca. In 2010, AstraZeneca announced its discovery of Truqap, and began to develop the drug as a potential treatment for various forms of cancer.

Following the marketing approval, Astex is eligible to receive a milestone payment from AstraZeneca on first commercial sale of the drug in the US as well as royalties on future sales.

Harren Jhoti PhD, President and Chief Executive Officer of Astex, UK, said: "We are incredibly proud that another of our drug discovery partnerships has resulted in such a successful outcome. We applaud our valued colleagues at AstraZeneca for their tenacity and exceptional work in the discovery and development of this first-in-class medicine."

"The early research was a great collaborative effort, and I would like to acknowledge the impressive pioneering research carried out by our colleagues at the ICR, including solving the 3D crystal structure of AKT, which was vital in enabling our initial drug discovery approach. This is also a great example of UK Biotech-Academia-Pharma collaboration and underlines the strength of the UK life sciences ecosystem."
