During the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in June 2021, Candel reported preliminary clinical data demonstrating an overall survival of 11.7 months in this difficult-to-treat patient population. The current presentation, focused on the biological findings of this study, showed the ability of CAN-3110 to induce immune activation both locally in the tumor microenvironment and systemically in peripheral blood.

Histologic analysis and molecular profiling of post-treatment brain samples demonstrated persistence of viral antigen associated with significant T-cell infiltration in the tumor parenchyma as well as a molecular signature consistent with local activation of innate and adaptive immunity. Analysis of post-treatment serum samples showed upregulation of pro-inflammatory cytokines and chemokines. These findings collectively indicate that CAN-3110 treatment can induce both local and systemic immune activation associated with an encouraging clinical response.

"There is a critical need for treatment options for patients with recurrent high-grade glioma. The data from this trial support the mechanistic approach of tumor cell-specific replication that was the intent of the CAN-3110 design," said Paul Peter Tak, MD, PhD, FMedSci, President and Chief Executive Officer of Candel Therapeutics. "The biomarker data presented at SITC (Free SITC Whitepaper), in conjunction with the overall survival data previously reported at ASCO (Free ASCO Whitepaper), are encouraging signals as we endeavor to bring novel oncolytic viral immunotherapies to patients with cancer."

About CAN-3110

CAN-3110 is an HSV replication-competent oncolytic virus engineered to enhance selective killing of cancer cells while sparing neighboring healthy cells. CAN-3110 selectively expresses ICP34.5, a key gene in HSV replication, in tumor cells that overexpress nestin, a cytoskeletal protein. Nestin is highly expressed in high-grade glioma cells and other tumor tissues, but it is absent in healthy adult brain tissue.

Candel is evaluating the effects of treatment with CAN-3110 in recurrent high-grade glioma.

Recent Clinical Developments

Validive

Monopar received clearance in multiple European countries to conduct its Phase 2b/3 VOICE clinical trial of Validive (clonidine HCl mucobuccal tablet) for the prevention of severe oral mucositis (SOM) in patients undergoing chemoradiotherapy (CRT) for oropharyngeal cancer.
Monopar continues to actively initiate additional clinical sites in both the U.S. and the EU for the Phase 2b clinical trial, which is on track to reach the interim in the first half of 2022.
There remains no FDA-approved prevention or treatment for CRT-induced SOM.
Camsirubicin

Camsirubicin, a propriety doxorubicin analog, has been engineered specifically to retain the anticancer activity of doxorubicin while minimizing the toxic effects on the heart.
In August 2021, Monopar received clearance from the U.S. Food and Drug Administration to proceed under an Investigational New Drug (IND) application with an open-label Phase 1b dose-escalation clinical trial evaluating camsirubicin plus growth factor support (pegfilgrastim/G-CSF) in patients with advanced soft tissue sarcoma.
In September 2021, Monopar initiated the Phase 1b clinical trial, and in October 2021, dosed the first patients.
Monopar continues to work on activating additional clinical sites in the U.S. for the Phase 1b clinical trial.
Results for the Third Quarter Ended September 30, 2021, Compared to the Third Quarter Ended September 30, 2020

Cash and Net Loss

Cash and cash equivalents as of September 30, 2021, were $22.3 million. Monopar anticipates that its current cash and cash equivalents will fund: the Phase 2b portion of the VOICE clinical trial; the commencement of the Phase 3 portion of the VOICE clinical trial; and the Phase 1b camsirubicin clinical trial through December 2022. The Company plans to raise additional funds and/or engage a partner within the next 12 months to complete the VOICE clinical program and continue camsirubicin clinical development beyond the Phase 1b clinical trial.

Net loss for the third quarter of 2021 was $2.5 million or $0.20 per share compared to net loss of $1.6 million or $0.15 per share for the third quarter of 2020.

Research and Development (R&D) Expenses

R&D expenses for the third quarter of 2021 were $1.8 million compared to $1.2 million for the third quarter of 2020. This increase of $0.6 million was primarily due to increases of $0.5 million for VOICE clinical trial expenses and $0.2 million for R&D personnel expenses offset by a decrease of $0.1 million for Phase 1b camsirubicin clinical trial expenses.

General and Administrative (G&A) Expenses

G&A expenses for the third quarter of 2021 were $0.6 million, compared to $0.4 million for the third quarter of 2020. This increase of $0.2 million was primarily due to an increase in G&A personnel expenses.

On November 12, 2021 Celyad Oncology SA (Euronext & Nasdaq: CYAD), a clinical-stage biotechnology company focused on the discovery and development of chimeric antigen receptor T cell (CAR T) therapies for cancer, reported three poster presentations on the Company’s allogeneic CAR T therapy programs at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) Annual Meeting taking place in Washington D.C. and virtually November 10-14, 2021 (Press release, Celyad, NOV 12, 2021, View Source [SID1234595448]).

"With these presentations, we demonstrate how we continue to execute on our strategic vision to develop differentiated next generation CAR Ts using our non-gene edited allogeneic approaches which are intended to provide multiple real-world benefits to patients," said David Gilham, Ph.D., Chief Scientific Officer of Celyad Oncology. "We believe our CAR T cells are the only allogeneic CAR T cells currently in human clinical trials that avoid generating double-strand DNA breaks. Combining with multiplexed shRNA and cytokine armoring, we believe this approach provides us with a dynamic platform for the generation of future allogeneic candidates."

Charles Morris, M.D., Chief Medical Officer of Celyad Oncology said, "In addition to the encouraging preclincal data presented, we are also on the cusp of initiating the KEYNOTE-B79 Phase 1b clinical trial in collaboration with MSD. We believe that KEYNOTE-B79 will be the first clinical trial to evaluate an allogeneic CAR T with an anti-PD-1 therapy in solid tumors. We look forward to evaluating whether the expected highly complementary mechanism of actions of CYAD-101 and KEYTRUDA could help to drive important clinical benefit in patients with refractory metastatic colorectal cancer with microsatellite stable disease where a high unmet medical need exists. We look forward to initiating the study in the coming weeks and providing clinical updates to the CYAD-101 program in 2022."

Key Highlights from SITC (Free SITC Whitepaper) Annual Meeting

Poster 107 – Armoring NKG2D CAR T cells with IL-18 improves in vitro and in vivo anti-tumor activity

This poster demonstrates the key role of Interleukin-18 (IL-18) in driving increased effector function of the NKG2D CAR T cells.
These data support the ongoing development of the Company’s shRNA-based allogeneic, IL-18-armored CAR T candidate CYAD-203 as well as future allogeneic IL-18-armored CAR T candidates.
Poster 146 – Evolving multiplexed shRNA to generate tailored CAR T cell therapy

Multiplexing short hairpin RNA (shRNA) within a single vector format ensures co-linked expression of the shRNA with therapeutic transgenes.
We continue to develop second-generation shRNA scaffold using multiplexed technology to produce novel allogeneic clinical candidates with bespoke, desired phenotypes and function produced using methods that avoid the generation of double strand DNA breaks.
Poster 407 – A Phase 1b KEYNOTE-B79 trial evaluating non-gene edited allogeneic CAR T-cells, CYAD-101, post FOLFOX preconditioning, followed by pembrolizumab, in refractory metastatic colorectal cancer patients

Clinical and translational results from the alloSHRINK Phase 1 trial evaluating the TCR Inhibitory Molecule (TIM)-based allogeneic NKG2D CAR T-cell product candidate CYAD-101 (NCT03692429) in patients with metastatic colorectal (mCRC) cancer suggest that treatment with sequential checkpoint inhibition following CYAD-101 with FOLFOX preconditioning could drive more durable clinical responses.
The KEYNOTE-B79 trial will therefore evaluate the safety and clinical activity of multiple infusions of CYAD-101 administered post FOLFOX preconditioning chemotherapy, followed by treatment with KEYTRUDA (pembrolizumab) in mCRC patients with microsatellite stable disease, according to a Simon’s two stage trial design.
The KEYNOTE-B79 clinical trial is expected to begin in fourth quarter 2021.
These ePosters will be available on the SITC (Free SITC Whitepaper) website starting today at 1 p.m. CET / 7 a.m. ET and in the Scientific Publications section of Celyad Oncology’s website.
