The poster highlights two lead molecules discovered from structure and property-guided drug discovery platform. The molecules demonstrate potent A2A/A2B dual antagonism across a variety of pathologically relevant models that recapitulate the high adenosine driven immunosuppression found in the tumour microenvironment (TME) across several cancers. To build differentiation and improve clinical translation, AI/ML driven virtual trials were employed to identify potential combination drugs, and to guide in patient selection during clinical development. BWC2094 and BWC2562 demonstrate synergistic activity in combination with approved cancer drugs in human peripheral blood assays and proprietary patient-derived ex vivo tumor explant platform as measured by a reduction in the tumor density and increased apoptosis/necrosis. Additionally, these molecules demonstrate good oral bioavailability in rodents and dogs and were found to be well tolerated for 14 days in dose-range finding toxicological studies in preclinical species. Based on the totality of evidence, BWC2094 is ready for IND submission.

Bugworks Research is at the forefront of developing novel small molecule drugs to combat hard-to-treat cancers and drug-resistant bacterial infections. The company is building a deep pipeline of differentiated oncology programs that target critical pathways involved in cancer progression and treatment evasion.

The ESMO (Free ESMO Whitepaper) Immuno-Oncology Congress is an annual event offering a forum to present the latest scientific and clinical developments in immunotherapy to diverse stakeholders with an interest to deliver innovative treatments for cancer. Attendees are invited to visit the Bugworks poster on December 7th, 2023, between 12.00-1.00 CET.

"Our fiscal fourth quarter concludes a productive year during which we took a number of critical steps that place us firmly in the execution phase of our pivot to a biotherapeutic manufacturing-first growth strategy," stated Dr. James A. Hayward, president and CEO of Applied DNA. "We closed on the strategic acquisition of Spindle Biotech that empowered the launch of our Linea IVT platform, initiated the build-out of an initial GMP manufacturing footprint to produce critical mRNA starting materials, acquired what we believe to be an enviable base of early-phase customers for both our Linea DNA and Linea IVT platforms, and affirmed our capacity for the rapid production of multi-gram quantities of Linea DNA. Cumulatively, these steps expand our relevance into the growing and diverse value chain of genetic medicine manufacturing with a near-term focus on enabling our customers to produce better mRNA faster.

"At our ADCL clinical lab and supply chain traceability segments, progress has been slower than hoped for due to the ongoing review of our pharmacogenomics assay and testing service by New York State Department of Health’s and as we pursue initiatives to migrate our seasonal cotton tagging business into a year-around revenue stream, respectively."

Continued Dr. Hayward, "Looking ahead to fiscal 2024, we believe that continued biotherapeutics segment momentum and anticipated continued expansion in genetic medicine manufacturing demand, particularly for mRNA, can drive segment growth in the coming fiscal year. Our optimism is founded in our proprietary Linea IVT platform that enables the cell-free, enzymatic production of critical mRNA starting materials with unprecedented flexibility, speed, scale, and costs. We believe that this platform offers the industry the ability to outperform conventional mRNA production processes at the exact time the industry is seeking differentiation and is embracing next-generation, fully enzymatic workflows."

"Furthermore, our planned GMP capacity for critical mRNA starting materials is expected to now come online in the first half of calendar 2024, subject to the availability of financing, that will for the first time enable us to support current and new customers’ migration to the clinic with mRNA drug candidates. We believe this capacity will be a catalyst for our procurement of larger-scale supply agreements for our platforms. Additionally, we will continue to invest for the future with a focus on platform optimization and data generation to enhance Linea DNA’s standing as an alternative source of DNA for all genetic medicines. While we expect fiscal 2024 to be a milestones-driven year for us given the biotherapeutics industry’s ongoing investment in mRNA, longer term, we believe the future of our Linea DNA platform is not constrained to critical starting materials for mRNA production and have already secured research use only orders and are starting to build a backlog for in vitro diagnostics, gene editing/therapy and adoptive cell therapy applications."

Summary Fourth Quarter Fiscal 2023 Financial Results:

Total revenues were approximately $780 thousand for the three-month period September 30, 2023, compared to $3.6 million for the same period in the prior fiscal year. The decrease in revenue of approximately $2.8 million was due to an expected decline in COVID-19 testing services revenue of $2.4 million driven primarily by cancellation of the testing contract with City University of New York (CUNY) in June 2023. The decrease was also due to a reduction in product revenue of $341 thousand. The decline in product revenues is primarily related to a decrease in the textiles market due to a decline year-over-year in cotton DNA tagging revenue.
Gross profit for the three-month period ended September 30, 2023, was $79 thousand, compared to $417 thousand for the three-month period ended September 30, 2022. The gross profit percentage was 10% and 12% for the three-month periods ended September 30, 2023, and 2022, respectively. The decline in gross profit year-over-year is due to a higher percentage of COVID-19 surveillance testing services revenue in the three-months ended September 30, 2022, that generated a higher gross profit compared to the same period in the current fiscal year.
Operating loss decreased to $4.2 million for the three-month period ended September 30, 2023, as compared to $4.3 million for the fourth quarter of fiscal 2022. The decrease in operating loss is the result of lower operating expenses during the fourth quarter of fiscal 2023 by $419 thousand, offset by the decline in revenue discussed above. The decrease in operating expenses was primarily due to a decrease in payroll and insurance expenses.
Net loss was $3.6 million for the three-month period ended September 30, 2023, compared to $665 thousand for the fourth quarter of 2022.
Excluding non-cash expenses, Adjusted EBITDA was a negative $3.5 million for the three-month period ended September 30, 2023, compared to a negative $3.4 million for the same period in fiscal 2022.
Cash and cash equivalents stood at $7.2 million on September 30, 2023, compared with $10.8 million as of June 30, 2023.

"With the recent initiation of Phase 1 dose escalation for XTX101 in combination with atezolizumab, we look forward to establishing a recommended Phase 2 dose in support of our plans to evaluate the combination in a Phase 2 trial in patients with microsatellite stable colorectal cancer (MSS CRC), including patients with liver metastases where there is an especially significant unmet need," said Katarina Luptakova, M.D., chief medical officer of Xilio. "The new Phase 1 data we reported for XTX101, which include 18 patients treated at the recommended Phase 2 dose of 150 mg Q6W, continue to demonstrate XTX101’s promising safety profile with primarily Grade 1 or 2 treatment-related adverse events. In addition to the previously reported confirmed partial response in a non-small cell lung cancer patient through 36 weeks, these new data also suggest further evidence of monotherapy anti-tumor activity in late-line and IO refractory patients at the recommended Phase 2 dose."

Updated Data from the Ongoing Phase 1 Clinical Trial for XTX101

As of the data cutoff date of November 13, 2023, 36 patients with advanced solid tumors had been administered XTX101 monotherapy, including 18 patients at the recommended Phase 2 dose and schedule (RP2D) of 150 mg once every six weeks (Q6W).

Patients treated at the RP2D of 150 mg Q6W were heavily pre-treated, with 83% of patients receiving three or more lines of anti-cancer therapy and 56% previously treated with an immunotherapy.

Preliminary Safety Data

At the RP2D of 150 mg Q6W, 18 patients (including 9 patients previously reported) were evaluable for safety as of the data cutoff date:

● Safety data were consistent with previously reported results. XTX101 monotherapy was generally well-tolerated with treatment-related adverse events (TRAE) primarily Grade 1 or 2, and no patients discontinued treatment due to a TRAE. In addition, as previously reported, only one patient had a dose reduction due to an adverse event.
● The most common TRAE of any grade (≥10% incidence) reported by investigators was fatigue (11%).
● As previously reported, investigators reported only two Grade 3 TRAEs: Grade 3 TRAE of diarrhea, which occurred after two doses and resolved after five days without steroid use, and one Grade 3 TRAE of dermatitis.

In addition, as previously reported, no Grade 4 or 5 TRAEs were reported by investigators across all dosing levels and dosing intervals.

Preliminary Anti-Tumor Activity Data

At the RP2D of 150 mg Q6W, 12 patients were evaluable for anti-tumor activity as of the data cutoff date:

● As previously reported, a confirmed partial response (PR) was observed in a patient with Stage 4 PD-L1 negative non-small cell lung cancer (NSCLC), including complete resolution of liver metastases. The confirmed PR continued through 36 weeks of treatment with XTX101, with the patient discontinuing treatment after week 36 due to an unrelated adverse event.
● Additional data reported today demonstrated a disease control rate (DCR) of 33% in late-line and IO refractory patients administered XTX101 monotherapy at the RP2D of 150 mg Q6W, consisting of the confirmed PR in the NSCLC patient and stable disease in three patients (triple-negative breast cancer, melanoma and microsatellite stable colorectal cancer (n=1 each)).

Preliminary Pharmacokinetic Data

As previously reported, consistent with the tumor-selective design for XTX101, preliminary pharmacokinetic analyses demonstrated 96% activation of XTX101 in a melanoma tumor and 73% activation in a metastatic liver lesion in a colorectal cancer patient, compared to minimal peripheral activation of XTX101 of 13% in both patients.

Poster Presentation

A copy of Xilio’s data presentation from the ESMO (Free ESMO Whitepaper) Immuno-Oncology Congress for XTX101 is available in the "Our Approach—Publications and Presentations" section of the company’s website at www.xiliotx.com.

Clinical Development Plans for XTX101

Xilio recently completed enrolling patients at the RP2D of 150 mg Q6W in monotherapy dose expansion and initiated enrollment in Phase 1 combination dose escalation to evaluate the safety, tolerability and efficacy of XTX101 in combination with atezolizumab.

As previously reported, subject to obtaining sufficient additional capital, Xilio plans to:

● Complete Phase 1 combination dose escalation and select a RP2D for XTX101 in combination with atezolizumab in the second quarter of 2024
● Subject to the results of Phase 1 combination dose escalation, initiate a Phase 2 trial to evaluate the safety and efficacy of XTX101 in combination with atezolizumab in patients with MSS CRC in the third quarter of 2024

About XTX101 (anti-CTLA-4) and the Phase 1 Monotherapy and Phase 1/2 Combination Clinical Trials

XTX101 is an investigational tumor-activated, Fc-enhanced, high affinity binding anti-CTLA-4 monoclonal antibody designed to block CTLA-4 and deplete regulatory T cells when activated (unmasked) in the tumor microenvironment (TME). The Phase 1 clinical trial is a first-in-human, multi-center, open-label trial designed to evaluate the safety and tolerability of XTX101 for the treatment of adult patients with advanced solid tumors. Xilio has completed enrollment in monotherapy dose escalation (Part 1A) and monotherapy dose expansion (Part 1B). Please refer to NCT04896697 on www.clinicaltrials.gov for additional details.

Xilio is currently evaluating the safety and tolerability of XTX101 in combination with atezolizumab (Tecentriq) in Phase 1 dose escalation in patients with advanced solid tumors, and subject to obtaining additional capital and the results of Phase 1 combination dose escalation, Xilio plans to evaluate the safety and efficacy of the combination in a Phase 2 trial in patients with microsatellite stable colorectal cancer (MSS CRC).

Sarclisa® (isatuximab) Phase 3 trial met primary endpoint of progression free survival in patients with newly diagnosed multiple myeloma not eligible for transplant

On December 7, 2023 Sanofi reported that the Phase 3 IMROZ trial evaluating the investigational use of Sarclisa (isatuximab) in combination with standard-of-care bortezomib, lenalidomide and dexamethasone (VRd) met its primary endpoint at a planned interim analysis for efficacy, demonstrating statistically significant improvement in progression-free survival (PFS) compared with VRd alone in transplant-ineligible patients with newly diagnosed multiple myeloma (MM) (Press release, Sanofi, DEC 7, 2023, View Source [SID1234638259]). This is also the second Phase 3 trial investigating Sarclisa in newly diagnosed patients to show superiority versus standard of care.

"The IMROZ trial outcome is promising for patients with newly diagnosed multiple myeloma who are transplant-ineligible, as there remains a significant unmet need for potential new therapies. First line therapeutic options are critical for all patients, but especially for those who are transplant-ineligible, given attrition rates in subsequent lines of therapy."

The safety and tolerability of Sarclisa observed in this trial was consistent with the established safety profile of Sarclisa and VRd.

Dietmar Berger, MD, PhD
Global Head of Development, Sanofi

"This is the second Phase 3 trial investigating Sarclisa in newly diagnosed patients to show superiority versus standard of care, reinforcing our belief in Sarclisa as a best-in-class medicine. These data underscore our commitment to advancing scientific innovation for people living with multiple myeloma, and we look forward to sharing more detail on Sarclisa’s potential to improve outcomes for patients receiving earlier lines of therapy."

Study results will be submitted for presentation at an upcoming medical meeting and form the basis of a future regulatory submission.

About the IMROZ trial

The randomized, multi-center, open label Phase 3 IMROZ clinical trial enrolled 484 patients with newly diagnosed transplant-ineligible MM across 104 centers spanning 21 countries. During the trial, Sarclisa was administered through an intravenous infusion at a dose of 10 mg/kg once weekly for five weeks during first 42-day cycle and once every two weeks in cycles 2 to 4 in combination with subcutaneous bortezomib, oral lenalidomide and intravenous or oral dexamethasone. Then Sarclisa was administered every 2 weeks from cycle 5 to 17 and every 4 weeks in cycles 18+ during 28-day cycles in combination with lenalidomide and dexamethasone at the standard dose, until disease progression, unacceptable safety profile or patient’s decision to stop the study treatment. The primary endpoint of IMROZ is progression-free survival. Key secondary endpoints include complete response rate, minimal residual disease negativity rate for patients with a complete response, very good partial response or better rate, overall survival. Other secondary endpoints are: overall response rate, time to progression, duration of response, time to first response, time to best response, progression-free survival on next line of therapy, progression-free survival by MRD status, sustained MRD negativity greater than or equal to 12 months rate, safety, pharmacokinetic profile, immunogenicity, disease-specific and generic health-related quality of life, disease and treatment-related symptoms, health state utility, and health status.1

The use of Sarclisa in combination with VRd in transplant-ineligible newly diagnosed MM is investigational and has not been fully evaluated by any regulatory authority.

About Sarclisa

Sarclisa is a monoclonal antibody that binds to a specific epitope on the CD38 receptor on multiple myeloma (MM) cells, inducing distinct antitumor activity. It is designed to work through multiple mechanisms of action including programmed tumor cell death (apoptosis) and immunomodulatory activity. CD38 is highly and uniformly expressed on the surface of MM cells, making it a potential target for antibody-based therapeutics such as Sarclisa.

Based on the Phase 3 ICARIA-MM study, Sarclisa is approved in >50 countries, including the U.S. and EU, in combination with pomalidomide and dexamethasone for the treatment of patients with relapsed refractory MM (RRMM) who have received ≥2 prior therapies, including lenalidomide and a proteasome inhibitor and who progressed on last therapy. Based on the Phase 3 IKEMA study, Sarclisa is also approved in 50 countries in combination with carfilzomib and dexamethasone, including in the U.S. for the treatment of patients with RRMM who have received 1–3 prior lines of therapy and in the European Union for patients with MM who have received at least 1 prior therapy. In the U.S., the generic name for Sarclisa is isatuximab-irfc, with irfc as the suffix designated in accordance with Nonproprietary Naming of Biological Products Guidance for Industry issued by the U.S. Food and Drug Administration (FDA).

Sarclisa continues to be evaluated in multiple ongoing Phase 3 clinical trials in combination with current standard treatments across the MM treatment continuum. It is also under investigation for the treatment of other hematologic malignancies, and its safety and efficacy have not been evaluated by any regulatory authority outside of its approved indication.

For more information on Sarclisa clinical trials, please visit www.clinicaltrials.gov.

About multiple myeloma

MM is the second most common hematologic malignancy.2 Since MM does not have a cure, most patients will relapse. Relapsed MM is the term for when the cancer returns after treatment or a period of remission. Refractory MM refers to when the cancer does not respond or no longer responds to therapy.

Updated Linvoseltamab Pivotal Data Demonstrated Strong Rates and Depth of Response in Patients with Heavily Pre-Treated Multiple Myeloma

On December 7, 2023 Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) reported that the primary endpoint analysis from the pivotal trial (LINKER-MM1) investigating linvoseltamab demonstrated high rates of deep and durable responses in patients with relapsed/refractory (R/R) multiple myeloma (MM) (Press release, Regeneron, DEC 7, 2023, View Source [SID1234638257]). These Phase 1/2 results are planned to be submitted to regulatory authorities, including to the U.S. Food and Drug Administration (FDA) this year. Linvoseltamab is an investigational BCMAxCD3 bispecific antibody designed to bridge B-cell maturation antigen (BCMA) on multiple myeloma cells with CD3-expressing T cells to facilitate T-cell activation and cancer-cell killing.

"Multiple myeloma remains an incurable disease, in which patients endure cycles of relapse and remission, resulting in a critical need for innovative medicines," said L. Andres Sirulnik, M.D., Ph.D., Senior Vice President, Translational and Clinical Sciences, Hematology at Regeneron. "With longer follow-up data on linvoseltamab, we’re seeing deep and durable responses with a complete response rate nearing 50% in a difficult-to-treat patient population who had received a median of 5 prior lines of therapy. Furthermore, in our trial, the regimen had a short monitoring time and a convenient, response-adapted administration schedule that enabled deep responders to go from every two-week to every four-week dosing. This regimen saved time for clinicians and patients, underscoring the potential for linvoseltamab as a patient-centric option in relapsed/refractory multiple myeloma."

At a median duration of follow-up of 11 months, an objective response rate of 71% as assessed by an independent review committee, with 46% achieving a complete response or better, was observed in patients treated with linvoseltamab 200 mg in the Phase 1/2 trial (n=117). After a minimum of 24 weeks of therapy, patients who achieved a very good partial response (VGPR) or better shifted from every two-week to every four-week dosing. These results build on an earlier data cut, with 8 months of median follow-up, that will be presented at the 65th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition from December 9 to 12 in San Diego, CA.

Among this group of patients, 27% of patients were over 75 years old, 16% had extramedullary plasmacytomas, 23% had bone marrow plasma cells ≥50%, and 39% had high-risk cytogenetics – representing a patient population with a high disease burden and typically poor prognosis. Additionally, 17% were Black or African American, mirroring rates that are representative of MM in the U.S.

Based on the latest data cut, all patients treated with 200 mg experienced an adverse event (AE), including 85% who experienced Grade ≥3 adverse events (AE). The most commonly occurring AE was cytokine release syndrome (CRS; 46%). Of the CRS cases, the majority (35%) were Grade 1, 10% were Grade 2 and there was one case (1%) of Grade 3 CRS. Adjudicated immune effector cell-associated neurotoxicity syndrome (ICANS) events occurred in 9 patients (8% all Grades); Grade 3 ICANS occurred in 3 patients, and no cases of ≥Grade 4 cases. All grade infections were observed in 73% of patients; 34% were Grade 3 or 4. Deaths due to treatment-emergent AEs on-treatment or within 30 days post last dose occurred in 14 patients (12%), of which 11 (9%) were due to infections.

The development program investigating linvoseltamab, including in earlier stages of the disease is underway. In the U.S., linvoseltamab has been granted Fast Track Designation for multiple myeloma by the FDA. Linvoseltamab is currently under clinical development, and its safety and efficacy have not been fully evaluated by any regulatory authority.

About the Phase 1/2 Trial
The ongoing, open-label, multicenter Phase 1/2 dose-escalation and dose-expansion trial is investigating linvoseltamab in patients with R/R MM. Among the 282 patients enrolled, all have received at least three prior lines of therapy or are triple refractory. Patients were administered linvoseltamab utilizing a step-up dosing regimen that was designed to help mitigate CRS.

The Phase 1 intravenous dose-escalation portion of the trial, which is now complete, primarily assessed safety, tolerability and dose-limiting toxicities across nine dose levels of linvoseltamab exploring different administration regimens. The Phase 2 dose expansion portion of the trial (LINKER-MM1) is further assessing the safety and anti-tumor activity of linvoseltamab, with a primary objective of ORR. Key secondary objectives include duration of response, PFS, rate of minimal residual disease negative status and overall survival.

About Multiple Myeloma
Multiple myeloma is the second most common blood cancer. Globally, there are over 176,000 new cases diagnosed annually and an estimated 35,000 people were diagnosed in the U.S. It is characterized by the proliferation of cancerous plasma cells (multiple myeloma cells) that crowd out healthy blood cells in the bone marrow, infiltrate other tissues and cause potentially life-threatening organ injury. Multiple myeloma is not curable despite treatment advances, and while current treatments are able to slow the progression of the cancer, most patients will ultimately experience cancer progression and require additional therapies.
