Chronic lymphocytic leukemia (CLL) patients face significant unmet needs, including the lack of treatment options for relapsed or refractory CLL, drug-induced resistance, and adverse events. Available BTK inhibitors can bind to off-target kinases, such as ITK and EGFR, causing side effects or can have limited long-term efficacy due to drug resistance, which most commonly occurs by the C481S mutation.

UBX-303 has been designed to demonstrate efficacy by degrading over-expressed BTK proteins and has a different modality than current BTK inhibitors. Its distinct mechanism of action, the decomposing and removal of BTK proteins in cells, is expected to bring about overall advantages, in particular demonstrating superior efficacy, overcoming resistance, and increasing selectivity for target proteins.

"UBX-303 showed excellent PK/PD profiles in the non-clinical studies conducted so far, and superior anti-cancer efficacy in the C481S mutant Xenograft mouse model as well as in the wild type. We expect UBX-303 to address unmet medical needs for B cell-related diseases, including CLL and DLBCL, and to expand its indications for immunological disorders." said BK Seo, CEO of Ubix Therapeutics.

About Degraducer
Degraducer is a technology that utilizes the ubiquitin-proteasome system (UPS), an intracellular degradation system. Degraducer is a bifunctional molecule where a "ligand", which binds to target protein, and a "binder", which binds to E3 ubiquitin ligase. In other words, Degraducer is a powerful inhibitor technology that enables target protein degradation and consequent therapeutic effects by placing a disease-related target protein nearby E3 ligase, which can then initiate the protein degradation system.

"We are very honored and proud to be laureates of the France Relance initiative. The French Government’s commitment to invest in strategic industries is an opportunity for MaaT Pharma, as a key player in the microbiome industry, to further pursue our development plans and to actively contribute to the biomanufacturing of innovative drugs in France. This is a team success, and this financing supports the efforts of women and men at MaaT Pharma who work tirelessly to deliver groundbreaking innovations in microbiome therapeutics," said Hervé Affagard, Founder and CEO at MaaT Pharma. "The France Relance program will support the development of our unique and innovative industrial processes that leverage all the functional diversity of the microbiome to deliver better outcomes in cancer treatment."

MEPA, supporting a new generation of microbiome therapies

MaaT Pharma has developed two approaches for its oncology-focused therapies. The first relies on healthy donor donations ("native" products) and aims to restore the gut microbiota of patients with liquid tumors (notably leukemia). The second is focused on the development of "synthetic" microbiome therapies, which are co-fermented and are designed to colonize the patient’s gut with a functional microbiome to improve response to treatment in patients with solid tumors.

MaaT Pharma’s unique pharmaceutical drug development platform relies on advanced artificial intelligence data analysis tools and on a proprietary technology for the co-fermentation of microbial ecosystems to support the design, development, and large-scale manufacturing of novel Microbiome Ecosystem Therapies (MET).

The grant funding will support a key step in developing this platform, namely the industrialization and standardization of co-fermentation processes according to cGMP manufacturing standards, as well as the manufacturing of clinical batches. Ultimately, MaaT Pharma’s manufacturing platform may be used to deliver a large range of microbiome ecosystem therapies in various indications.

Accelerating the development of products in immuno-oncology

The MEPA program is a new step in Maat Pharma’s development as it supports the expansion of its indications to include solid tumors and the acceleration of its immuno-oncology program.

Recent studies have shown that the gut microbiome composition may improve the therapeutic effect of immune checkpoint inhibitors (ICI). In particular, a patient’s gut microbiome richness1 and diversity2 are predictors of their response to ICI3. Two pilot clinical studies also suggest that gut microbiota transfer from ICI-responding donors to non-responders can restore the response in the latter4.

With its therapies, MaaT Pharma aims to synthetically replicate a responder microbiota, combining high richness and diversity with selected functional networks in each indication of interest to improve the response to immune checkpoint inhibitors.

The clinical study, to be conducted in close collaboration with the Gastroenterology & Hepatology department of the Erasmus MC, is entitled the ‘HEB-PEP study’. The project starts in August 2021 and the clinical phase is expected to begin in 2022. It will provide an insight into which dose of ISA104 is safe, tolerable and potentially effective in chronic HBV patients.

ISA104 is an immunotherapy based on ISA’s Synthetic Long Peptide (SLP) technology designed to direct a strong and specific immune response against the hepatitis B virus (HBV), with the aim to cure chronically infected patients. It will be ISA’s next program to go into clinical development, with its lead program ISA101b in late-stage clinical trials for human papillomavirus type 16 (HPV16) induced cancers.

ISA Pharmaceuticals has previously demonstrated that SLP immunotherapy for HPV16 can eradicate HPV16-induced pre-cancerous lesions1,2,3. ISA, in collaboration with Erasmus MC, has developed a set of antigenic long peptides to create an SLP vaccine, ISA104, aimed to boost the patient’s immune response to clear cHBV.

Leon Hooftman, Chief Medical Officer of ISA Pharmaceuticals commented: "We are excited to announce this TKI project which will enable us to bring a next product to the clinic from ISA’s pipeline. It is a new highlight of our long-standing collaboration with Erasmus MC. This project will test the safety and immune-stimulatory capacity of ISA104, by taking an important next step to potentially curing patients with chronic Hepatitis B, a tremendous global health burden."

Chronic HBV infection affects an estimated 257 million patients worldwide and 20–30% of adults who are chronically infected will develop cirrhosis and/or liver cancer4. Currently, no effective curative treatments exist. Therapeutic vaccines harbour great potential to cure chronic HBV aiming to achieve viral control and clearance. SLP immunotherapies act through induction of potent and durable anti-viral adaptive immune responses.

On July 20, 2021 Clarity Pharmaceuticals, a clinical stage radiopharmaceutical company focused on the treatment of serious disease, reported that its 64Cu SAR-bisPSMA clinical trial in patients with confirmed prostate cancer is open for recruitment at two sites, GenesisCare CTA Medical Clinic, Perth and Nepean Hospital, Sydney (Press release, Clarity Pharmaceuticals, JUL 20, 2021, View Source [SID1234584961]).

Clarity’s Executive Chairman, Dr Alan Taylor, commented, "We are very excited to open this trial for patients with newly diagnosed prostate cancer using our optimised PSMA agent, 64Cu SAR-bisPSMA, that has the novel combination of two targeting agents attached to our SAR Technology. The preclinical data to date is compelling, with both higher tumour uptake and greater tumour retention compared to the single targeted products utilised by other radiopharmaceutical products on the market, and we look forward to recruiting our first patient for this trial shortly."

The PROPELLER trial is a Phase I Positron Emission Tomography (PET) imaging trial of participants with confirmed prostate cancer using 64Cu SAR-bisPSMA. It is a 30-patient clinical trial conducted across three sites in Australia (NCT04839367)1. PROPELLER is a multi-centre, blinded review, dose ranging, non-randomised study of 64Cu-SAR-bisPSMA administered to patients with confirmed prostate cancer prior to radical prostatectomy. The primary endpoints of the trial are safety, tolerability and efficacy in the detection of primary prostate cancer compared to histopathology.

Dr Taylor said: "Prostate cancer is one of the largest indications in oncology, and due to the logistical, manufacturing and imaging issues related to other radiopharmaceuticals, represents a lucrative opportunity for us to enter this space with our Targeted Copper Theranostics (TCT) platform. Clarity’s centralised manufacture and broad distribution model coupled with the flexibility of imaging at later time points, gives us confidence to believe that we can provide a large patient population with early, accurate and precise detection of prostate cancer and improve patient outcomes. We look forward to further progressing the development of our SAR-bisPSMA product and exploring the benefits of our TCT platform for patients with prostate cancer, including in our upcoming US based 64Cu/67Cu bis-PSMA theranostic trial (SECuRE trial (NCT04868604)2 which is due to commence shortly. The progress of these two trials will get us one step closer to our ultimate goal of developing better treatments for children and adults with cancer."

On July 20, 2021 Micronoma, the first cancer detection company to harness tumor-associated circulating microbial biomarkers to diagnose cancer at an early stage via microbiome-driven liquid biopsy technology, reported a collaboration with the University of New South Wales (UNSW), Sydney for a $4 million grant from the Australian Government to fund research into hepatocellular carcinoma (HCC), the most common type of primary liver cancer (Press release, Micronoma, JUL 20, 2021, View Source [SID1234584976]).

The collaboration, led by Associate Professor Amany Zekry and Professor Emad El-Omar from UNSW Medicine & Health will enable the development of microbial-based biomarkers powered by artificial intelligence for early detection of liver cancer. Micronoma’s Chief Scientific Officer, Eddie Adams, joins these world-class, multi-disciplinary experts at UNSW in the fields of liver disease, liver cancer, microbiome, metabolomics, and artificial intelligence as a co-principal investigator on the grant.

This research will use machine learning to examine thousands of microbiome plasma features to discover, validate, and translate microbial-derived biomarkers for the early detection of HCC, thus improving the chances of survival of HCC patients and making effective risk disease stratification possible.

"This collaboration with UNSW combines a rare and exciting set of expertise in liver cancer and gut microbiome with our proprietary method of analyzing circulating microbiome signatures. Importantly, being awarded this grant by the Australian Government serves as a strong external validation of our technique and will serve to showcase Micronoma’s unique approach to diagnostics," Micronoma CEO Sandrine Miller-Montgomery said. "There has been growing interest in the compelling link between circulating microbiome signatures and early detection since our publication in Nature. Developing a method to enable the identification of robust microbial plasma biomarker signatures of HCC is in our product pipeline and this collaboration enables us to fast-track product development."

"Our ongoing collaboration with Micronoma strengthens the innovative potential of this research. Micronoma is currently the only cancer diagnostic company in the world that uses microbial DNA signatures in the blood (mb-DNA) to detect early-stage cancer," said Professor Zekry. "Their minimally invasive microbiome-driven liquid biopsy approach is focused on detecting early-stage lung cancer and will provide valuable expertise in establishing an HCC-related microbiome platform."

The diagnostic implications of microbiome markers in liquid and tissue biopsies are extensive, and Micronoma is prepared to lead the way on helping prevent unnecessary suffering caused by later-stage cancer diagnosis, as well as potentially enabling personalized and less invasive treatments at the earliest stages of cancer.
