The SPRINT project aims to revolutionize the management of patients with CTCL and deliver a new cure paradigm as a standard-of-care. CTCL affects about one in 100,000 adults worldwide each year, nearly tripling in last 30 years. The impact on the quality of life of patients is severe, and the median overall survival rate is less than 5 years in the advanced stages. There is no clear understanding of the underlying factors guiding disease progression.

The multidisciplinary SPRINT consortium gathers internationally renowned physicians and researchers as well as drug discovery and artificial intelligence specialists to investigate the immune tumor microenvironment (TME) of CTCL, understand the mechanism of immuno-resistance, develop a non-invasive prognostic tool and bring new innovative therapeutic solutions to the clinic. The group includes five world-class academics:
UPCité, INSERM, Hospices Civils de Lyon, AP-HP, CHU Bordeaux, two highly innovating companies (Domain Therapeutics and TheraPanacea), while being endorsed by Medicen, the European Reference Network for Rare Hematological Diseases (EuroBloodNet), the French Study Group on Cutaneous Lymphomas (GFELC) – a national network supported by the French National Cancer Institute (INCa), and the patients association ELLyE

Domain and the SPRINT consortium will utilize a triad approach, building upon previous discoveries of extensive investigation into the TME in CTCL, including:

Implementation of an innovative strategy to improve treatment-agnostic early prognostication, through an effective synergy of domain-driven and data-driven artificial intelligence
Validation of a molecular signature of response to mAbs
Innovative drug development targeting tumor cells and the TME in the mechanisms of resistance with mAbs to provide long-term responses
Dr. Stephan Schann, Vice-President of Research at Domain Therapeutics, commented: "Cutaneous T-cell lymphoma is a rare type of cancer, and is largely considered an incurable disease with only few patients responding to current treatments. The grant that we have been awarded by the RHU SPRINT consortium will support the progress of DT-7012, an anti-CCR8 monoclonal antibody which has incredible potential as a best-in-class therapeutic, into the clinic. We are proud to take part in the RHU SPRINT consortium as we aim to turn more non-responder patients into responders."

Professor Adèle de Masson, RHU SPRINT Project Coordinator at Saint-Louis Hospital, Paris, said: "I would like to thank the Agence Nationale de la Recherche (ANR) for this significant support. There is a need for new treatments to address the severe impact on quality of life that cutaneous T-cell lymphoma has on patients, ranging from skin damage to secondary infections, pain, and fatigue, and survival rates. I am hopeful that Domain Therapeutics and the other recipients of the RHU SPRINT consortium grants will help improve the lives of CTCL patients worldwide and I look forward to the outcomes."

Dr Anthony Johnson, President and CEO, Domain Therapeutics, said: "We are extremely pleased for the support and further validation from the RHU for our GPCR targeting immuno-oncology pipeline. Domain was already awarded a first RHU grant, RHU CONDOR for Sarcoma, in the previous campaign, leveraging another proprietary asset. Being successful two consecutive years is unique and highlights the excellence of our science and collaborators. We are excited to work with the government and our partners in this second consortium, RHU SPRINT."

Domain previously announced the nomination of novel drug candidate DT-7012, an anti-CCR8 monoclonal antibody depleting tumor-infiltrating regulatory T cells (Tregs), with best-in-class potential in CTCL and solid tumors. Domain’s target is a highly strategic approach to derive efficient novel immunotherapies that increase the clinical success rate of treatments in non-responding patients with cancer, and the Company expects to start a Phase I study of DT-7012 by mid-2025.

Genialis and Debiopharm set up biomarker discovery collaboration

On January 25, 2024 Genialis, the RNA-biomarker company, and Debiopharm, a privately-owned, Swiss-based biopharmaceutical company aiming to establish tomorrow’s standards of care to cure cancer and infectious diseases, reported to have reached an agreement to define and discover biomarkers within the DNA Damage Repair (DDR) biology space to predict the clinical benefit of one or more drugs in Debiopharm’s pipeline (Press release, Debiopharm, JAN 25, 2024, View Source [SID1234639473]). The initial phase kicked off this month, deploying Genialis’ biology-first, machine learning-enabled ResponderIDTM framework to develop predictive biomarkers for DDR-directed therapies.

"Debiopharm continues to lead the oncology field in adopting artificial intelligence solutions at various stages across our preclinical and clinical development programs. Genialis’ expertise and cutting-edge technologies are an ideal fit to help us make the smartest translational decisions and advance our drugs to reach the right patients," said Bertrand Ducrey, CEO of Debiopharm.

Many cancers exhibit deficiencies in one or more DNA damage response pathways. Various classes of approved and investigational drugs aim to exploit known sensitivities; however, the heterogeneous biology of DNA damage response means that one drug only fits some, and combinations may prove essential. Biomarkers will help select patients whose cancer biologies are best suited to treatment with the right drug targeting the active disease mechanism.

"DNA damage response is among the most exciting biological domains of cancer drug development today and an area in which Debiopharm is working on several exciting molecules," said Carolina Haefliger, Head of Translational Medicine at Debiopharm. "Genialis’ biology-first approach allows us to collaborate in a truly scalable way, incorporating novel AI-based solutions in our programs."

Using biomarkers increases the odds of advancing an oncology clinical asset to the next trial phase by 5-12 fold[1]. However, post-approval, many of the best drugs achieve clinical benefit in only 30-40 percent of patients, and even those existing targeted therapies considered successful and supported by a biomarker can benefit from further refinement of patient tailoring strategies.

"Genialis’ RNA biomarkers have proved especially well-suited to support the development of new drugs targeting complex biological systems," said Mark Uhlik, Vice President of Biomarker Discovery at Genialis. "Debiopharm is working on some really promising molecules, and Genialis’ biomarkers will help ensure these drugs have the best possible chance of clinical success."

Genialis is based in Boston, Mass., and will attend PMWC in Santa Clara, Calif., from January 23-25, 2024. To request a meeting or for more information on ResponderID, please email [email protected] or visit www.genialis.com

Debiopharm is headquartered in Lausanne, Switzerland, and will be presenting at the 7th Annual DDR Inhibition Conference in Boston from January 29-30, 2024.

About DNA-Damage Repair (DDR)
When cells have damaged DNA, they need to undergo a repair process called DDR to be able to survive. Cancer cells use their hyperactive DDR response to divide and grow uncontrollably, which promotes cancer expansion. Inhibition of DDR, particularly in combination with other anticancer agents, induces an overall arrest in the uncontrollable cancer cell cycle. This ultimately activates a self-destruction program in cancer cells. DDR inhibitors are currently being tested in preclinical and clinical studies.

First Patient Dosed in Phase 2 Portion of Aulos Bioscience’s Phase 1/2 Clinical Trial for AU-007, a Computationally Designed IL-2 Antibody for Solid Tumor Cancers

On January 25, 2024 Aulos Bioscience, an immuno-oncology company working to revolutionize cancer care through the development of best-in-class IL-2 therapeutics, reported dosing of the first patient in the initial Phase 2 expansion cohorts of its Phase 1/2 clinical trial evaluating AU-007 for treatment of unresectable locally advanced or metastatic cancers (Press release, Aulos Bioscience, JAN 25, 2024, View Source [SID1234639471]). AU-007 is a human IgG1 monoclonal antibody designed to harness the power of interleukin-2 (IL-2) to eradicate solid tumors, and the first AI-designed human monoclonal antibody to be tested in a clinical trial. Phase 1 data demonstrate that AU-007 is currently the only IL-2 agent that can reduce regulatory T cells (Tregs), which suppress the immune system.

"Dosing of the first patient in the Phase 2 portion of our AU-007 Phase 1/2 study marks a significant milestone as we advance development of this promising, novel IL-2 therapeutic for the treatment of solid tumor cancers," said Aron Knickerbocker, Aulos Bioscience’s chief executive officer. "AU-007 was created to solve pressing safety and efficacy challenges associated with IL-2 therapeutics, and we are encouraged by ongoing new Phase 1 data that indicate clinical activity in several heavily pre-treated patients whose tumors progressed through checkpoint inhibitors. We are grateful to the participating patients and investigators in this clinical trial, and look forward to enrolling additional patients and presenting clinical data from the Phase 2 expansion cohorts later this year."

Aulos’ Phase 1/2 clinical trial is a two-part, open label, first-in-human study evaluating the safety, tolerability, immunogenicity and clinical activity of AU-007 in patients with unresectable locally advanced or metastatic cancer. The initial Phase 2 expansion cohorts focus on melanoma and renal cell carcinoma (RCC), with AU-007 administered every two weeks in combination with a single loading dose of low-dose, subcutaneous Proleukin (aldesleukin; recombinant human IL-2), or with AU-007 and low-dose, subcutaneous Proleukin, both administered every two weeks.

Created by Biolojic Design, AU-007’s unique computational design allows it to bind precisely to the portion of IL-2 that binds to CD25, which prevents IL-2 from binding to high-affinity IL-2 receptors on Tregs, vasculature, pulmonary tissue and eosinophils. This redirects IL-2 to medium-affinity receptors on effector T cells (Teffs) and natural killer (NK) cells, which expand and kill tumor cells. Phase 1 dose escalation cohort data presented at two separate medical meetings last fall demonstrate that when AU-007 is administered to patients as monotherapy or in combination with low doses of Proleukin, the number of immunosuppressive Tregs decreases and the numbers of Teffs and NK cells increase. Additionally, data indicate that AU-007 is well tolerated and tumor shrinkage was observed in patients with melanoma, bladder, kidney, head and neck, and lung cancers.

About AU-007
AU-007 is a computationally designed, human IgG1 monoclonal antibody that is highly selective to the CD25-binding portion of IL-2. With a mechanism of action unlike any other IL-2 therapeutic in development, AU-007 leverages IL-2 to reinforce anti-tumor immune effects. This is achieved by preventing IL-2, either exogenous or secreted by effector T cells, from binding to trimeric receptors on regulatory T cells while still allowing IL-2 to bind and expand effector T cells and NK cells. This prevents the negative feedback loop caused by other IL-2-based treatments and biases the immune system toward activation over suppression. AU-007 also prevents IL-2 from binding to CD25-containing receptors on eosinophils, as well as vasculature and pulmonary endothelium, which may significantly reduce the vascular leak syndrome and pulmonary edema associated with high-dose IL-2 therapy.
