ReACT (Re-energized adoptive cell transfer), combines CAR-T cell therapy with microbial immunotherapies, such as bacteria and oncolytic viruses, to synergistically treat solid tumors. Invented by Dr. Weiguo Cui, senior investigator, Versiti Blood Research Institute, ReACT T cells possess tumor targeting receptors as well as an added receptor that extends T cell activity when in the presence of tumor specific microbial immunotherapies. Its advantages include modification of the tumor microenvironment, localized activity, broad targeting of tumor antigens, and prevention of T cell exhaustion.

Longbow’s initial target for ReACT is bladder cancer, where Dr. Cui has engineered immune cells to express a novel CAR recognizing BCG, the standard of care in post resection bladder cancer therapy. The ReACT-BCG construct has been evaluated in a mouse model of bladder cancer, where it showed significant improvements in survival, tumor volume and immune cell markers. Dr. Cui said, "Currently, 60% of bladder cancer patients will experience recurrence within two years of tumor resection. ReACT has the potential to radically improve the prognosis for these patients."

Longbow also plans to extend the application of ReACT beyond initial bladder cancer uses, as ReACT T cells can be engineered to recognize and synergize with any bacterial immunotherapy or oncolytic virus targeting solid tumors. Kurt Rote, Co-Founder, stated, "For years, the field has been wanting to combine immunotherapy bacteria and oncolytic virus with CAR-T cells. Longbow is doing so in a novel, synergistic fashion, and is dedicated to getting this promising treatment to patients."

Mablink Bioscience and Emergence Therapeutics Enter Into a Licensing Agreement to Develop Antibody Drug Conjugate as a Potential Cancer Therapy

On October 21, 2021 Mablink Bioscience S.A.S. a biotechnology company developing a pipeline of ADC based on its proprietary PSARlink drug-linker technology and Emergence Therapeutics AG, a European biopharmaceutical company developing novel antibody drug conjugate (ADC) immuno-therapeutics to treat cancers with high unmet needs reported that they entered into a Licensing Agreement (Press release, Mablink Bioscience, OCT 21, 2021, View Source [SID1234591752]). Under the terms of the agreement, Emergence Therapeutics will use a PSARlink drug-linker developed by Mablink to develop an ADC targeting Nectin-4, a protein overexpressed in several severe cancers.

Jack Elands, CEO of Emergence Therapeutics said: "Mablink Bioscience’s technology, PSARlink, which is based on a hydrophilic linker using a polysarcosine arm, enabled us to design a Nectin-4 ADC loaded with the cytotoxic agent of our choice, whilst retaining the antibody’s pharmacological properties. This technology has the potential to widen the therapeutic index of an ADC and to make our Nectin-4 ADC a best-in-class. The preclinical data we obtained so far are very encouraging in this regard." Jean-Guillaume Lafay, CEO of Mablink Bioscience added: "We have developed a unique technology that we believe solves the core issue that impaired so many ADC developments. Grafting cytotoxic molecules to an Antibody usually creates a rather hydrophobic ADC, which is correlated with poor pharmacological properties (low drug-exposure and general toxicity issues). While Mablink Bioscience develops its own drug candidates targeting several difficult-to-treat cancers, we are delighted to be joined by Emergence Therapeutics in our effort to develop the 3rd generation of ADCs and to bring new, more efficient, therapeutic options to cancer patients."

Pursuant to the agreement, Mablink Bioscience is entitled to receive milestone and royalty payments, based on the development of the Nectin-4 ADC.

About PSARlink

PSARlink drug-linkers are a chemical physical link that can be placed between an antibody and a chosen cytotoxic molecule to be delivered into tumor cells. PSARlink’s unique structure "masks" the cytotoxic molecules, especially hydrophobic compounds, and provides a "stealthy" property to such antibody drug conjugates, enabling them to stay longer in the body, giving them more time to destroy tumor cells. At the same time, making ADC stealth avoids most of the damage typically caused by such molecules to healthy cells: PSARlink-based ADC are better tolerated. These improvements translate into a 10-fold increase of the therapeutic index observed in animal models, a potentially game changing factor for future clinical success.

Highlights for the third quarter 2021

Launch and Market Access efforts for Idefirix in Europe are progressing as planned in early launch countries. Reimbursement has been secured in Sweden, the Netherlands and Finland.
Health Technology Assessment (HTA) dossiers have been submitted in ten countries, including UK, Germany, Norway and Israel and most recently in Italy and Scotland during the third quarter. Hansa expects to complete HTA filings in all EU5 by year-end, with France and Spain expected to be submitted in Q4 2021.
Growing number of patient candidates identified as select leading transplantation centers get clinically ready to transplant this underserved population and prioritization programs and policies are adjusted to HLA-incompatible kidney patients, who cannot access an organ through existing allocation systems.
Marketing Authorization Application for Idefirix submitted in Switzerland and Israel.
European Society for Organ Transplantation (ESOT) Congress in Milan – Hansa-sponsored symposium and KOL meetings with very strong interest across entire European transplant community. An ESOT workstream with leading transplantation KOLs has been formed to advance European clinical guidelines for desensitization practices in incompatible kidney transplant patients. Workstream expected to be concluded by year-end.
Patient recruitment in the Phase 2 clinical studies in active antibody mediated rejection (AMR) and Guillain-Barré Syndrome (GBS) has been accelerated by initiation of new centers. In the AMR and GBS trials, 19 and 14 patients, respectively, out of a target of 30 patients in each of the studies have now been enrolled. Completion of enrollment continues to be expected by H2’21/H1’22, with a first data read-out in both studies expected in the second half of 2022, as previously guided.
Anti-Glomerular Basement Membrane (Anti-GBM): In the U.S., dialogue with FDA initiated regarding regulatory path forward, which is expected to conclude later this year as previously guided. In Europe, constructive regulatory advice meeting held with German health authorities BfArM; Hansa is now preparing for dialogue with the European Medicines Agency (EMA).
Partnership with Sarepta and preclinical collaboration with argenx moving forward according to plan.
Hansa Biopharma awarded "Great Place to Work" certification for second consecutive year.

Søren Tulstrup, President and CEO of Hansa Biopharma, comments

"We continue to make good progress in advancing our clinical, commercial and corporate strategy with solid progress in our efforts to build and advance a pipeline of valuable drug candidates for rare immunologic diseases and launch Idefirix in Europe. We see Idefirix as a potential new transformative therapy that can bring hope to the thousands of highly sensitized patients across the continent who are currently waiting for a compatible kidney transplant. With this novel therapy, we are paving a new path and changing the transplantation ecosystem to accommodate transplants for incompatible kidney patients.

Our goal is to have a positive impact on patients as we work closely with the transplant community to reshape the area of desensitization and integrate Idefirix into clinical practice as a new standard-of-care. We do this in a very focused way – center by center, one patient at a time. We are taking this strategic approach as Idefirix is the first and only approved drug to enable kidney transplants in highly sensitized patients in the EU, who are incompatible with a deceased donor, and the long-term market uptake of this innovative product is highly dependent on successful early experiences in key early adopter centers. Operationally, our Market Access activities in Europe continue according to plan in the early launch countries as evidenced by the recent positive Pricing and Reimbursement decisions by the authorities in the Netherlands and Finland. In addition, we are pleased to have executed agreements with the relevant regions in Sweden on the basis of the June 2021 decision by the national New Therapies Council to recommend Idefirix in highly sensitized patients.

In the U.S., the first site is now open for recruitment in our randomized controlled clinical trial in kidney transplants and we expect the first patient to be enrolled in the fourth quarter. The study initation marks an important milestone for Hansa Biopharma’s efforts to access the U.S. market. The new trial will target 64 highly sensitized patients with a cPRA score of ≥99.9%, representing the group of patients with the highest unmet medical need. We expect to enroll patients at 12-15 leading transplantation centers across the U.S. and that the U.S. trial will generate valuable experience at these key centers.

In our ongoing Phase 2 programs for GBS and AMR, we have initiated additional centers in Q3 to accelerate patient enrollment. We now have 12 centers open for recruitment in AMR and 8 in GBS and expect to open additional centers in the fourth quarter to meet our target of completing enrollment H2’21/H1’22, as previously guided, assuming no further escalation of the COVID-19 pandemic. As of October 21, 2021, 19 out of a target of 30 patients have now been enrolled in the AMR study and 14 out of a target of 30 patients have been enrolled in the GBS study.

Further, we have now initiated dialogue with the FDA on our anti-GBM program. As previously guided, we aim to achieve alignment on the regulatory path forward later this year. I am also pleased to announce a new study in 12 patients in the U.S. to assess whether imlifidase in combination with bortezomib, belatacept, rituximab and IVIg can optimize patient outcomes in highly sensitized patients with donor specific antibodies (DSA) rebound and antibody mediated kidney transplant rejection (AMR). The study will be run at the NYU Langone Transplant Institute and is expected to commence next year.

Regarding our strategic partnerships, our preclinical collaboration with argenx is moving forward according to plan. The preclinical focus of the collaboration aims at understanding potential benefits of combining imlifidase with efgartigimod, argenx’FcRn inhibitor.

Within gene therapy, our partnership with Sarepta to assess imlifidase as a pretreatment to Sarepta’s gene therapy programs in Duchenne and Limb-Girdle Muscular Dystrophy is also progressing according to plan. If positive preclinical data is generated we expect imlifidase to move into the clinic as a next step.

Lastly, I also want to highlight that Hansa Biopharma AB was recently awarded certification as a Great Place to Work for the second consecutive year. The certification as a Great Place to Work reflects our successful efforts over the past years to not only build and maintain a high performance team, but also to create a rewarding and stimulating workplace for our employees.

I look forward to keeping you updated on progress in our mission to leverage our unique IgG-cleaving enzyme technology platform to develop innovative, lifesaving and life-altering immunomodulating therapies, bring these to the patients with rare diseases who need them and generate value to society at large."
