About T-Cell Engagers

CD3 T-cell engagers are bispecific antibodies that guide the immune system to find and eliminate cancer cells by binding both cancer-killing T cells and tumor targets at the same time. Developing effective T-cell engagers requires two parental antibodies—a CD3-binding arm that fine-tunes T-cell activation and a tumor-binding arm with high specificity for cancer cells. The small number of available CD3-binding antibodies that can effectively fine-tune T-cell responses has been a barrier to T-cell engager development. To address this barrier, AbCellera developed a complete T-cell engager platform that includes fully human, developable CD3-binding antibodies with unique binding and functional properties. By combining these antibodies with OrthoMabTM, its clinically validated multispecific engineering platform, and its antibody discovery and development engine, AbCellera’s T-cell engager platform is designed to bring new cancer medicines to the clinic faster.

Nicolas Poirier, Chief Executive Officer of OSE Immunotherapeutics comments: "OSE’s key priorities for 2023 and beyond will lie in the successful conduct of the new Tedopi pivotal Phase 3 program, along with the maximization of the near-term value of Lusvertikimab while strengthening our partnership business-model assuring recurrent revenues from our first-in-class programs. The full funding of these strategic programs will be secured in due course through additional financial resources to deliver on our goals for the benefit of both the patients and our stakeholders. OSE has today a solid late-stage clinical and preclinical diversified portfolio in immuno-oncology (IO) and immuno-inflammation (I&I). The increased interest of the scientific and medical community in cancer vaccine, in particular Tedopi, encourages us to stay strategically focused and committed to make our drug candidate available to all eligible cancer patients in secondary resistance. We also look forward to the Lusvertikimab Phase 2 data readouts in ulcerative colitis in the next months and to generate additive value in both I&I and IO with our pre-IND OSE-230 and BiCKI-IL7 programs. In parallel, at research level, we will continue to strengthen our first-in-kind platform built at the intersection of Antibody Engineering, Data Science, Artificial Intelligence (AI) and novel RNA Therapeutics technologies which is generating exciting clinical opportunities for future next-generation immunotherapies."

Anne-Laure Autret-Cornet, Chief Financial Officer of OSE Immunotherapeutics, adds: "We have strengthened our cash position and secured new financing in H1-2023 to extend our financial visibility for over the next 12 months. In parallel, we significantly reduced our cash burn compared to last year after a strict review of strategic expenses and prioritization for out-licensing. This financial strategy allows us to pursue strategic investments on Tedopi and Lusvertikimab while pursuing innovative research programs to increase their value and interests. Our force is based on our recurrent €20 million average annual turnover these last 5 years, driven mainly by collaborations and licensing agreements with pharma companies. This business model based mostly on non-dilutive revenues remains our priority and will be further reinforced."

As of June 30, 2023, available cash amounted to €15 million, giving a financial visibility until Q4 2024.

During the first half of 2023, OSE Immunotherapeutics secured:

(1) An equity financing line with Vester Finance, set up on April 27, 2023. This financing has triggered at the end of September a capital increase of €11.6 million (without any discount on the share price at the date of signature). To supplement its financial resources and in order to extend its financial visibility until the fourth quarter of 2024, OSE Immunotherapeutics signed on 27 September 2023, an extension to this equity financing line agreement with Vester Finance, at the same conditions1.

This extension, approved by the Board of Directors of September 27, 2023, acting on delegation from the general assembly meeting of shareholders of June 22, 20232, relates to a maximum of 900,000 shares of the Company, representing a maximum of 4,16% of the share capital, that Vester committed to subscribe on its own initiative, over a maximum period of 24 months, subject to certain usual contractual conditions.

Assuming that the totality of this additional line of financing is used in full, a shareholder holding 1.00% of the capital of OSE Immunotherapeutics before its establishment, would see his stake increase to 0.96% of the capital on an undiluted basis3 and 0.96% of the share capital on a diluted basis4.

This transaction does not give rise to the preparation of a prospectus subject to the approval of the "Autorité des Marchés Financiers," based on Article 1 of the Prospectus Regulation granting an exemption when a transaction relates to a dilution less than 20% of the Company’s share capital.

The number of shares issued under this agreement and admitted to trading will be communicated monthly on the Company’s website.
Loans and "PGE Resilience"

The Company obtained the formal agreement on loans for a total amount of €5.3 million with the collective support of "La Région Pays de la Loire," Bpifrance and its banking pool composed by banks CIC, Crédit Mutuel and BNP to finance its strategic R&D programs. Favorable conditions were granted for these loans, with an interest range of 2-4% and reimbursement timelines within 3 to 5 years. Part of these loans is composed by a "PGE Resilience" ("Prêt Garanti par l’État") loan guaranteed by the French State, implemented in the context of the Ukrainian crisis.

At the end of June 2023, €3.1 million have been drawdown. The balance has been received in Q3 2023.
€1.5 million in funding from Bpifrance for the development of a companion diagnostic for the cancer vaccine Tedopi in non-small cell lung cancer.
This available cash will enable the Company to finance its clinical development and R&D costs for earlier stage products.

During the first half of 2023, the Company recorded a consolidated net result of €-11,9 million.

Current operating expenses were €14.9 million (versus €19.4 million for the same period in 2022) of which 77% are related to R&D. After a strategic review of costs and programs, operating expenses dropped dawn by 25% compared to H1 2022.

The Board of Directors of September 27, 2023, has approved the Company’s semester accounts as of June 30, 2023. The full "Half-year financial report" (Regulated information) is available on: View Source The limited review procedures on the consolidated accounts have been performed.

First Patient Receives Gamida Cell’s Omisirge™ (omidubicel-onlv)

On September 27, 2023 Gamida Cell Ltd. (Nasdaq: GMDA), a cell therapy pioneer working to turn cells into powerful therapeutics, reported that the first patient has received a stem cell transplant with Omisirge (omidubicel-onlv) (Press release, Gamida Cell, SEP 27, 2023, View Source [SID1234635486]).

"This is a significant milestone for Gamida Cell, advancing our mission of delivering potentially curative therapies to patients with cancer," said Abbey Jenkins, President and Chief Executive Officer of Gamida Cell. "This patient will be the first of many who have new hope for a cure thanks to the availability of Omisirge as a new stem cell transplant donor source. This is why we do the work that we do – to make a difference for people with cancer."

Omisirge was approved by the U.S. FDA in April 2023 for use in adults and pediatric patients 12 years and older with hematologic malignancies who are planned for umbilical cord blood transplantation following myeloablative conditioning to reduce the time to neutrophil recovery and the incidence of infection.

Gamida Cell has already exceeded its 2023 launch goals, with 15 transplant centers onboarded across the United States and confirmed coverage with payers that cover 90% of commercial lives. Gamida Cell is actively engaged with more than 90% of the top 70 transplant centers, which conduct approximately 80% of transplants. An increasing number of patients are being enrolled in Gamida Cell Assist, which signals a transplanter’s intent to use Omisirge as the donor source.

"The launch of Omisirge is progressing very well in terms of payer coverage, transplant center onboarding and transplanter interest in using Omisirge as a donor source," said Michele Korfin, Chief Operating and Chief Commercial Officer of Gamida Cell. "We recognize the importance of making sure eligible patients can access Omisirge. To appropriately manage our cash, we launched with a limited investment and field footprint. The positive launch progress and strong interest from transplant centers now warrant expanding that investment and the team from four to eight account managers by the start of 2024. We are encouraged by transplanter feedback that Omisirge may both increase the number of patients able to access an appropriate donor source and address some limitations of other donor sources."

Approximately 8,000 stem cell transplants are performed in the U.S. each year in patients with hematologic malignancies1 and another 1,700 patients are estimated to be eligible for transplant but unable to find a donor.2 The ability to find a donor is historically more challenging for racially and ethnically diverse populations than for patients who are white.3 Gamida Cell market analyses indicate that Omisirge has the ability to capture approximately 20% of allogeneic stem cell transplant market share by ~2028.

Omisirge Indication

Omisirge is a nicotinamide modified allogeneic hematopoietic progenitor cell therapy derived from cord blood indicated for use in adults and pediatric patients 12 years and older with hematologic malignancies who are planned for umbilical cord blood transplantation following myeloablative conditioning to reduce the time to neutrophil recovery and the incidence of infection.

Important Safety Information for Omisirge

BOXED WARNING: INFUSION REACTIONS, GRAFT VERSUS HOST DISEASE, ENGRAFTMENT SYNDROME, AND GRAFT FAILURE

Infusion reactions may be fatal. Monitor patients during infusion and discontinue for severe reactions. Use is contraindicated in patients with known allergy to dimethyl sulfoxide (DMSO), Dextran 40, gentamicin, human serum albumin or bovine material.
Graft-versus-Host Disease may be fatal. Administration of immunosuppressive therapy may decrease the risk of GvHD.
Engraftment syndrome may be fatal. Treat engraftment syndrome promptly with corticosteroids.
Graft failure may be fatal. Monitor patients for laboratory evidence of hematopoietic recovery.
Contraindications

OMISIRGE is contraindicated in patients with known hypersensitivity to dimethyl sulfoxide (DMSO), Dextran 40, gentamicin, human serum albumin, or bovine products.

Warnings and Precautions

Hypersensitivity Reactions

Allergic reactions may occur with the infusion of OMISIRGE. Reactions include bronchospasm, wheezing, angioedema, pruritis and hives. Serious hypersensitivity reactions, including anaphylaxis, may be due to DMSO, residual gentamicin, Dextran 40, human serum albumin (HSA) and bovine material in OMISIRGE. OMISIRGE may contain residual antibiotics if the cord blood donor was exposed to antibiotics in utero. Patients with a history of allergic reactions to antibiotics should be monitored for allergic reactions following OMISIRGE administration.

Infusion Reactions

Infusion reactions occurred following OMISIRGE infusion, including hypertension, mucosal inflammation, dysphagia, dyspnea, vomiting, and gastrointestinal toxicity. Premedication with antipyretics, histamine antagonists, and corticosteroids may reduce the incidence and intensity of infusion reactions. In patients transplanted with OMISIRGE in clinical trials, 47% (55/117) patients had an infusion reaction of any severity. Grade 3-4 infusion reactions were reported in 15% (18/117) patients. Infusion reactions may begin within minutes of the start of infusion of OMISIRGE, although symptoms may continue to intensify and not peak for several hours after the completion of the infusion. Monitor patients for signs and symptoms of infusion reactions during and after OMISIRGE administration. When a reaction occurs, pause the infusion and institute supportive care as needed.

Graft-versus-Host Disease

Acute and chronic GvHD, including life-threatening and fatal cases, occurred following treatment with OMISIRGE. In patients transplanted with OMISIRGE Grade II-IV acute GvHD was reported in 58% (68/117). Grade III- IV acute GvHD was reported in 17% (20/117). Chronic GvHD occurred in 35% (41/117) of patients. Acute GvHD manifests as maculopapular rash, gastrointestinal symptoms, and elevated bilirubin. Patients treated with OMISIRGE should receive immunosuppressive drugs to decrease the risk of GvHD, be monitored for signs and symptoms of GvHD, and treated if GvHD develops.

Engraftment Syndrome

Engraftment syndrome may occur because OMISIRGE is derived from umbilical cord blood. Monitor patients for unexplained fever, rash, hypoxemia, weight gain, and pulmonary infiltrates in the peri-engraftment period. Treat with corticosteroids as soon as engraftment syndrome is recognized to ameliorate symptoms. If untreated, engraftment syndrome may progress to multiorgan failure and death.

Graft Failure

Primary graft failure occurred in 3% (4/117) of patients in OMISIRGE clinical trials. Primary graft failure, which may be fatal, is defined as failure to achieve an absolute neutrophil count greater than 500 per microliter blood by Day 42 after transplantation. Immunologic rejection is the primary cause of graft failure. Monitor patients for laboratory evidence of hematopoietic recovery.

Malignancies of Donor Origin

Two patients treated with OMISIRGE developed post-transplant lymphoproliferative disorder (PTLD) in the second-year post-transplant. PTLD manifests as a lymphoma-like disease favoring non-nodal sites. PTLD is usually fatal if not treated. The etiology is thought to be donor lymphoid cells transformed by Epstein-Barr virus (EBV). Serial monitoring of blood for EBV DNA may be warranted in patients with persistent cytopenias. One patient treated with OMISIRGE developed a donor-cell derived myelodysplastic syndrome (MDS) during the fourth-year post-transplant. The natural history is presumed to be the same as that for de novo MDS. Monitor life-long for secondary malignancies. If a secondary malignancy occurs, contact Gamida Cell at (844) 477-7478.

Transmission of Serious Infections

Transmission of infectious disease may occur because OMISIRGE is derived from umbilical cord blood. Disease may be caused by known or unknown infectious agents. Donors are screened for increased risk of infection, clinical evidence of sepsis, and communicable disease risks associated with xenotransplantation. Maternal and infant donor blood is tested for evidence of donor infection. See full Prescribing Information, Warnings and Precautions, Transmission of Serious Infections for list of testing performed. OMISIRGE is tested for sterility, endotoxin, and mycoplasma. There may be an effect on the reliability of the sterility test results if the cord blood donor was exposed to antibiotics in utero. Product manufacturing includes bovine-derived reagents. All animal-derived reagents are tested for animal viruses, bacteria, fungi, and mycoplasma before use. These measures do not eliminate the risk of transmitting these or other transmissible infectious diseases and disease agents. Test results may be found on the container label and/or in accompanying records. If final sterility results are not available at the time of use, Quality Assurance will communicate any positive results from sterility testing to the physician. Report the occurrence of transmitted infection to Gamida Cell at (844) 477-7478.

Transmission of Rare Genetic Diseases

OMISIRGE may transmit rare genetic diseases involving the hematopoietic system because it is derived from umbilical cord blood. Cord blood donors have been screened to exclude donors with sickle cell anemia, and anemias due to abnormalities in hemoglobins C, D, and E. Because of the age of the donor at the time cord blood collection takes place, the ability to exclude rare genetic diseases is severely limited.

ADVERSE REACTIONS

The most common adverse reactions (incidence > 20%) are infections, GvHD, and infusion reaction.

Please see full Prescribing Information, including Boxed Warning.

Akeso Announced FDA Clearance of IND for CD47 Monoclonal Antibody (AK117) in Combination with Azacitidine in Myelodysplastic Syndromes

On September 27, 2023 Akeso, Inc. (the Company, Akeso, 9926.HK) reported that the U.S. Food and Drug Administration (FDA) has cleared the Company’s Investigational New Drug (IND) application for AK117, a next generation CD47 monoclonal antibody in combination with azacitidine for treatment of patients with newly diagnosed higher-risk myelodysplastic syndromes (MDS) (Press release, Akeso Biopharma, SEP 27, 2023, View Source;combination-with-azacitidine-in-myelodysplastic-syndromes-301941140.html [SID1234635485]). The upcoming study, known as a randomized, double-blind, global multi-center Phase II study, is set to be conducted in the United States.

Based on the favorable safety profile and remarkable efficacy of AK117 in combination with azacitidine for the treatment of newly diagnosed higher-risk MDS patients, as showcased in previous studies, and the strong demand from MDS patients worldwide, Akeso has conducted comprehensive scientific communication and discussions with the FDA. Akeso believes that this study will facilitate the global development process for AK117.

"With more time and space, we will consistently implement a comprehensive international strategy to explore and advance our innovative therapies. For the benefit of more patients, we will leverage global resources to improve the success rate of AK117." Said Dr. Michelle Xia, the founder, Chairwoman, CEO, and President of Akeso.

Anemia is a significant symptom of MDS, and effectively managing anemia and minimizing blood transfusion are crucial aspects of disease control. In contrast to other anti-CD47 antibody drugs, which have been reported to worsen anemia in MDS patients by causing RBC hemagglutination, AK117 eliminated RBC hemagglutination and also enabled to maintain full effectiveness of CD47 blockade on tumor cells, which resulted in excellent antitumor efficacy and favorable safety profile of AK117.

The previous studies of AK117 in combination with azacitidine showed positive results in patients with newly diagnosed higher-risk MDS. AK117 reduced anemia and transfusion requirements among MDS patients, and demonstrated a favorable safety profile and remarkable efficacy. These findings position AK117 as a promising therapeutic option for MDS patients worldwide.

Notably, Akeso is consistently advancing the development of AK117 as a therapeutic agent in combination with various agents such as PD-1/CTLA-4 and PD-1/VEGF, for treatment of multiple hematologic malignancies and solid tumors.

About Ligufalimab (AK117)

AK117, independently developed by Akeso, is a next generation of humanized lgG4 anti-CD47 antibody without hemagglutination effect. AK117 can bind to CD47 expressed on tumor cells and block the interaction between CD47 and SIRPα, in order to enhance the phagocytic activity of phagocytes on tumor cells, thereby inhibiting the growth of tumors.
