The presentation will highlight the capabilities of the company’s TCXpress platform and its ability to rapidly clone TCRs against specific targets from single T cells. This work enabled the discovery of BlueSphere’s first clinical candidate, a TCR T-cell therapy directed against the minor histocompatibility antigen (miHA) HA-1. The company anticipates filing its first IND by the end of 2022. The TCXpress platform has also enabled the discovery of four new TCRs reactive against other relevant miHAs, in addition to HA-1. BlueSphere plans to announce details on these other targets later this year.

Title: High Throughput Cloning Reveals Diverse Properties of anti-HA-1 T Cell Receptors

Presenter: Dr. Sawa Ito, hematologist/oncologist at UPMC Hillman Cancer Center and Assistant Professor, Division of Hematology-Oncology and Department of Immunology at the University of Pittsburgh School of Medicine.

"To maximize the potential of our novel, click chemistry-based platform and continue expanding our portfolio of programs, clinical experience and leadership are critical," said José M. Mejía Oneto, M.D., Ph.D., Founder and CEO of Shasqi. "As we reach the end of dose escalation of SQ3370, we will initiate Phase 2 studies in advanced sarcomas and other solid tumors. In addition, we are rapidly advancing our second program toward the clinic, which activates high doses of monomethyl auristatin E, a commonly used antibody-drug conjugate payload, at the tumor. Now is the perfect time to add the deep expertise in clinical strategy and execution that both Steve and Scott bring to the team. We look forward to their contributions and working with them."

"Shasqi has made tremendous progress advancing SQ3370 into and through the clinic and building a robust pipeline of click chemistry-activated therapeutics to harness potent payloads and target them precisely to the tumor," said Dr. Abella. "I’m excited to join the company’s mission and help expand the reach of their platform."

"A click chemistry-based approach has enormous potential to dramatically improve the efficacy of powerful therapies that can be localized at the tumor site using a variety of delivery methods such as direct injection or biomarker targeting," said Dr. Wieland. "I look forward to seeing where we can take this technology and what the next iterations of Shasqi’s approach can achieve in improving the cancer therapeutic landscape and the lives of patients."

Dr. Steve Abella

Dr. Abella has been working in oncology clinical research for nearly 35 years, including more than 12 years in the pharmaceutical industry. Before joining Shasqi, he served as Chief Medical Officer at Vida Development Sciences. Prior to Vida, Steve served as Chief Medical Officer at BioClin Therapeutics. Prior to that, he served as Senior Director at Gilead Sciences where he led the non-Hodgkin’s lymphoma and leukemia drug development efforts and served as a core member of the oncology senior leadership team. Prior to Gilead, he served as Executive Director at Amgen, predominately responsible for the white cell franchise (Neulasta/Nepogen) and led global development efforts across clinical research and medical affairs. Before he joined the biopharmaceutical industry, he spent 15 years in academic oncology, serving as a Professor of Pediatric, Oncology, and Medicine at the Barbara Ann Karmanos Cancer Institute where he focused on stem cell transplantation and oncology clinical trials. Steve completed his fellowship and residency training at Wayne State University School of Medicine after graduating with a degree in medicine from the Universidad Central del Este. He attended the University of Pennsylvania for undergraduate studies.

He received his master’s and Ph.D. in Psychology/Biopsychology with a minor in Neuropharmacology from the University of Arizona, Tucson, AZ, and an MBA in Management from Webster University, St. Louis, MO.

About CAPACTM and SQ3370

SQ3370 is the first click chemistry-based treatment to be tested in humans. It utilizes Shasqi’s proprietary CAPAC platform, an approach that activates cancer drugs at a tumor with decreased systemic toxicity. Shasqi is validating its platform with SQ3370, which is designed to activate a powerful chemotherapeutic, doxorubicin, at the tumor site. The investigational product is based on the chemical reaction between a drug protected through a trans-cyclooctene modification (a protodrug) and a tetrazine-modified biopolymer. The biopolymer is injected into the target tumor lesion, where it precisely activates an intravenously infused protodrug. Shasqi believes its click-chemistry approach can improve the efficacy and safety of many existing therapeutics across various modalities with a limited therapeutic window.

Pelemed, ‘FLT3/RET double inhibitor’ AML “ASCO announcement”

On May 24, 2022 PeLeMed reported that it will present the preclinical study results of the FLT3/RET dual inhibitor candidate ‘PLM-102’ at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2022 (ASCO 2022) (Press release, PeLeMed, MAY 24, 2022, View Source [SID1234615603]).

PLM-102, a target anticancer drug candidate of Pelemed, targets even FLT3-resistant mutations (D835Y, F691L) that develop resistance after treatment with existing drugs such as ‘Xospata, gilteritinib’, an FLT3 inhibitor for the treatment of acute myeloid leukemia (AML). do. Pelemed is aiming to submit an IND to the Korean and US Food and Drug Administration (FDA) next year.

At this ASCO (Free ASCO Whitepaper), Pelemed will present △in vitro biochemical, cellular △ in vitro efficacy, △mode of action, etc. of PLM-102 along with the existing drug Zosphata. .

Specifically, PLM-102 showed an excellent Kd value for binding even at a lower dose compared to the FLT3/AXL inhibitor Zosphata in the binding affinity test. The Kd value of PLM-102 was 0.019 nM (vs 1.4 nM) for normal FLT3 and 0.01 to 1.1 nM (vs 0.16 to 19 nM) for TKD mutant, which showed a lower Kd value than that of Zosphata.

Pelemed’s PLM-102 resulted in effective cell growth inhibition at a lower dose than Zosphata in acute myeloid leukemia cell lines (MV4-11, MOLM-13, MOLM-14) and Ba/F3 cell lines with FLT3 mutations. showed

A tumor mouse model administered with a dose of 5 mg/kg or more of PLM-102 showed complete remission with tumor growth inhibition when administered orally once a day. In addition, Pelemed explained that the anticancer effect was also confirmed in drug-resistant double mutation models (ITD/F691L, ITD/D835Y) administered with PLM-102.

Pelemed confirmed the RET inhibitory effect of PLM-102 and the decomposition effect of RET and FLT3 proteins. This proteolysis phenomenon did not appear in Zosphata and another approved RET inhibitor, Roche’s ‘Gavreto, pralsetinib’, indicating a differentiated mechanism of RLM-102, the company explained.

Acute myeloid leukemia (AML) is a type of blood cancer in which tumor cells appear in the blood or bone marrow. FLT3 mutations are observed in about 30% of acute myeloid leukemia patients. It is known that 50% of patients with acute myeloid leukemia who have achieved complete remission with high-intensity chemotherapy experience recurrence, and patients with FLT3 mutations are known to have a higher risk of recurrence and a lower survival rate than those who do not.

An official from Pelemed said, "PLM-102, which has a differentiated mechanism, is under non-clinical research this year.
