Alligator Bioscience has previously shown that mitazalimab synergizes effectively with immune checkpoint inhibitors and vaccines. The abstract, titled "Mitazalimab, a potent CD40 agonist with potential for combination with chemotherapy", demonstrates that mitazalimab synergizes with chemotherapy, notably FOLFIRINOX, leading to improved long-term survival in a preclinical tumor model.

"The new preclinical data are very encouraging. Together with the clinical data of mitazalimab from a previous Phase I study, where mitazalimab was well tolerated up to 1200 µg/kg, these data support the upcoming clinical Phase II study of mitazalimab in combination with chemotherapy in pancreatic cancer patients," says Per Norlén, CEO of Alligator Bioscience.

Mitazalimab is a human CD40 agonistic antibody developed for immunotherapy of cancer. The chemotherapy cocktail FOLFIRINOX kills tumor cells leading to increased release of tumor antigens. Activation of CD40 leads to improved presentation of tumor antigens, and the consequent T cell priming and initiation of T cell-dependent anti-tumor responses.

Health Canada Clears Pacylex Pharmaceuticals for New Phase 1 Clinical Trial to Evaluate PCLX-001 Capsules in the Treatment of Hematologic and Solid Tumor Cancers

On March 11, 2021 Pacylex Pharmaceuticals, an oncology company unlocking a new approach to cancer therapy, reported the receipt of a No Objection Letter from Health Canada on March 8, 2021, opening the way for a planned Phase 1 Trial of PCLX-001 in relapsed/refractory B-cell Non-Hodgkin Lymphoma and advanced solid malignancies (Press release, Pacylex Pharmaceuticals, MAR 11, 2021, View Source [SID1234645064]). Pacylex is developing this NMT inhibitor, PCLX-001, as a first in class therapy for various cancers. PCLX-001 is believed to be the first NMT inhibitor that will be clinically tested.

Three principal investigators will oversee the clinical study at three clinical sites in Canada: Dr. John Kuruvilla at Princess Margaret Cancer Centre in Toronto, Dr. Randeep Sangha at the Cross Cancer Institute in Edmonton and Dr. Laurie Sehn at the British Columbia Cancer Center in Vancouver.

"Health Canada approval to conduct this trial is an exciting step in bringing PCLX-001 into the clinic. As a first-in-class agent with a new mechanism of action, we plan to see how well people with lymphoma and other cancers tolerate the drug and hope to see some of them benefit," said Dr. Sangha, MD FRCPC, Director, Clinical Trials Unit, Cross Cancer Institute.

Dr. Kuruvilla added "We are excited to be working with other Canadian research teams and Pacylex to study a novel therapy with a unique mechanism of action in patients with lymphoma". Dr. Kuruvilla is Clinician Investigator in the Cancer Clinical Research Unit (CCRU), Princess Margaret Cancer Centre.

Clinical site preparations are underway for the open label, dose escalation, Phase 1 clinical trial, principally to evaluate the safety of PCLX-001. The study will enroll 20-30 patients and the Company anticipates that enrollment will begin in the second quarter of 2021.

Pacylex received a milestone-based Alberta Innovates AICE grant in 2020 to help fund this study, and the No Objection Letter triggered the first milestone payment from this grant. The Alberta Cancer Foundation and the Cure Cancer Foundation both provided support for this research.

PCLX-001

PCLX-001 is a small molecule, first-in-class N-myristoyltransferase (NMT) inhibitor, originally developed by the University of Dundee Drug Discovery Unit as part of a program to treat African sleeping sickness funded by Wellcome Trust. Pacylex is developing PCLX-001, which has excellent oral bioavailabilty, to treat leukemia and lymphoma. PCLX-001 selectively kills cancer cells and completely regresses (eliminates) tumors in animal models of acute myeloid leukemia (AML), diffuse large B-cell lymphoma (DLBCL) and Burkitt’s lymphoma (BL). PCLX-001 has also been shown to inhibit the growth of lung and breast cancer tumors in animal models. In leukemia, lymphoma and breast cancer patients, the level of NMT2 is correlated with survival, suggesting an important biological role in these cancers. In tests using cultured cancer cells in vitro, PCLX-001 is at least ten times as potent as Ibrutinib (Imbruvica) and Dasatinib (Sprycel), two clinically approved drugs currently used to treat hematologic malignancies.

BioInvent presents proof-of-concept data on anti-FcyRIIB antibody BI-1607 at AACR Annual Meeting 2021

On March 11, 2021 BioInvent International AB ("BioInvent") (Nasdaq Stockholm: BINV), reported the publication of proof-of-concept data on a novel, fully human FcγRIIB-blocking antibody, BI-1607, at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2021, being held virtually April 10-15 and May 17-21 (Press release, BioInvent, MAR 11, 2021, View Source,c3303983 [SID1234576469]).

"The data on BI-1607 are very exciting and provide proof-of-concept of its ability to enhance anti-cancer immunity, illustrated by its ability to boost activity and overcome resistance to CTLA-4-based therapy," said Martin Welschof, CEO of BioInvent. "We are looking forward to advancing BI-1607 into clinical development and expect to submit a clinical trial application during H2 2021. It will be BioInvent’s fourth drug candidate in clinical development, further demonstrating the strength and productivity of our technology platform."

Understanding mechanisms and overcoming resistance to distinct classes of antibody drugs has the potential to further improve cancer outcomes, explains the AACR (Free AACR Whitepaper) abstract, entitled "A novel FcγRIIB-blocking antibody to enhance FcγR-dependent antitumor immunity". BI-1607 has a novel mechanism-of-action and is designed to enhance FcγR-dependent antitumor immunity. The abstract outlines how BI-1607 enhances the therapeutic activity of anti-CTLA-4 in responsive (MC38) or resistant (CT26) experimental disease models (syngeneic immune competent) and that a triple combination – of BI-1607, anti-PD-1 and low dose anti-CTLA-4 – significantly enhanced survival in a B16 tumor model not responsive to checkpoint blockade.

BioInvent’s lead compound BI-1206, evaluated in two separate Phase I trials for hematological or solid tumors, is one of three ongoing drug candidates in clinical development. The company initiated a Phase I/IIa trial of anti-TNFR2 antibody BI-1808 in January 2021 and a Phase l/lla trial of the novel oncolytic vaccinia virus BT-001, together with partner Transgene, in March 2021.

The primary endpoint is biochemically verified continuous abstinence during the last 4 weeks of treatment in the 6 and 12-week cytisinicline treatment arms compared to placebo. Each treatment arm will be compared independently to the placebo arm and the trial will be determined to be successful if either or both of the cytisinicline treatment arms show a statistical benefit compared to placebo. The trial is expected to complete enrollment by the middle of the 2021.

Data Highlighting Smoker Dissatisfaction with Available Treatments Presented at SRNT

Achieve data presented at the SRNT Annual Meeting in February 2021 provided insights into current and former smokers’ perceptions on currently available cessation treatment options. In a survey of 1,122 individuals, overall satisfaction and perceived efficacy with available therapies was low, with the best performing treatment leading to satisfaction in less than one-third of the respondents. The study found a majority of prescription cessation medication users do not complete their full 3-month

course of therapy, with 53% reporting less than 1 month of use. Smokers reported side effects and lack of efficacy as the most common reason for discontinuation or lack of initiation with varenicline or bupropion.

Data Elucidating Vaping/e-Cigarette Users Behavior and Quitting Intentions Presented at SRNT

Two Achieve posters were presented at the SRNT Annual Meeting in February 2021 reporting findings from a survey of 508 users of nicotine vape products. The results showed that the primary reason to initiate e-cigarettes/vaping was to quit combustible cigarettes. While proven successful in the cohort of subjects who only utilize vape, dual users, those who vape but also continue to smoke, reported 2-times heavier nicotine use than their counterparts. Additionally, the data indicated that 73% of e-cigarette/vape users intend to quit vaping in the next 3-12 months. Of those who intend to do so in the next 3 months, more than half reported they would be "very/extremely likely to try a new prescription product" to help them quit.
