HIV infant model opens new avenues for research

Drug Target Review | October 09, 2019

An animal model to test HIV infection in infants could lead to biomarkers that predict viral rebound after ART interruption. Researchers have developed an animal model to test HIV infection and therapies in infants, allowing them to develop biomarkers to predict viral rebound after antiretroviral therapy (ART) interruption. The new model allows for immune interventions against the HIV envelope protein through the use of a SHIV, as opposed to a SIV, a simian immunodeficiency virus that has a very different virus envelope than HIV. It takes advantage of recent advances in SHIV development that fully replicated the clade C viruses that are involved in the majority of infant HIV transmission. Researchers at the University of Pennsylvania, US have developed a new way to make SHIV, in which mutations are made around the CD4 binding site that HIV uses for entry into cells. “This opened up a new treasure trove of SHIVs that would be available for this type of model,” said Sallie Permar MD, PhD, professor of paediatrics in the Division of Infectious Diseases.

Janux Therapeutics Submits IND Application for JANX008

Janux | December 29, 2022

Janux Therapeutics, Inc. is a clinical-stage biopharmaceutical company that uses its Tumor Activated T Cell Engager (TRACTr) and Tumor Activated Immunomodulator (TRACIr) platforms to develop a diverse pipeline of novel immunotherapies. On December 27, 2022, the company announced that it had submitted an investigational new drug (IND) application for JANX008 to U.S. Food and Drug Administration, an EGFR-TRACTr in (SCCHN). The company is pleased to announce its second IND. It considers this a big step forward for its TRACTr platform, which has also helped many next-generation immunotherapies move forward. JANX008 is made in a particular way to avoid cytokine release syndrome and the known harmful effects of EGFR in on-target healthy tissue. As a result, the company thinks it could be easier to treat EGFR-expressing cancers in many ways. JANX008 is a double-masked TRACTr that conceals both the EGFR-binding and T-cell-specific binding domains (CD3). JANX008 exhibited minor cytokine release syndrome and healthy tissue toxicity in preclinical studies. Besides, it demonstrated superior safety and pharmacokinetic (PK) qualities compared to unmasked TCEs. These data and JANX008's strong manufacturability qualities justify its continued development as a potential therapy for solid tumors. About theJanux Janux Therapeutics is a clinical-stage business developing immunotherapies that target cancers without affecting healthy tissue. The company uses platform masking to generate innovative therapeutic candidates that address T-cell engager toxicity and efficacy limitations. It develops next-generation cancer therapeutics using TRACTR platform. Janux Therapeutics focuses on developing medically-validated T cell engagers (TCEs). Its pipeline includes PSMA, EGFR, and TOP2 efforts. All of its programs are IND-enabling or discovery.

Exelixis and Sairopa Announce FDA Clearance of IND Application

Exelixis | February 14, 2023

On February 13, 2023, Exelixis, Inc., a leading global oncology firm innovating next-generation medicines and regimens at the forefront of cancer care and Sairopa B.V. (Sairopa), a renowned firm developing novel therapeutics for cancer by modulating the patient's immune system, announced that FDA has approved Sairopa's Investigational New Drug (IND) Application to assess the pharmacokinetics and safety of ADU-1805 in adults with advanced solid tumors. ADU-1805, being a monoclonal antibody active against all human SIRPα alleles, has the potential to reach a broader patient population than existing SIRPα-directed therapeutics. ADU-1805 has the potential to boost the immune system's ability to combat tumors by suppressing SIRPα, an important immuno-suppressive component of the tumor microenvironment. When compared to other SIRP family members, ADU-1805 has been designed to bind preferentially to SIRPα, which may improve its capacity to stimulate immune cells. In accordance with the clinical development and option agreement announced in November 2022, Exelixis has the option to obtain an exclusive, global license to commercialize and develop ADU-1805 and other anti-SIRPα antibodies after reviewing data from predetermined phase 1 clinical studies of ADU-1805 to be conducted by Sairopa during the option period. This IND approval results in a $35 million milestone payment to Sairopa to be paid in the first quarter of 2023. About Exelixis Founded in 1994, Exelixis is a leading global oncology firm at the vanguard of cancer care, developing next-generation drugs and regimens. Fueled by bicoastal centers of research and development expertise, its clinically distinct pipeline of small molecules, antibody-drug conjugates, and other biotherapeutics is quickly expanding its product portfolio to address a growing spectrum of tumor types and indications. In addition, the company has demonstrated an excellent track record of endurance in the face of adversity after working in the competitive biotech industry for over 25 years. Its main product's success has provided it with a robust commercial basis, allowing re-energizing research activities and team expansion in clinical development, drug discovery, and commercial areas.
