RQ Biotechnology Ltd. (RQ Bio) has announced that the first of its discovered monoclonal antibodies to prevent COVID-19 in vulnerable patients, AZD-3152, has entered clinical trials.
Although ovarian cancers appear to be immunologically active, they do not respond well to immunotherapy in the clinic. In a study published on Dec. 14, 2022, in Nature, a multidisciplinary team at Memorial Sloan Kettering Cancer Center (MSK) led by Sohrab Shah and Dmitriy Zamarin has uncovered several mechanisms of immune evasion that can help explain why ovarian cancers have been resistant to immunotherapy to date.
With $20 million raised in a series B round led by Brandon Capital and Tenmile, Aravax Pty Ltd. is poised to begin phase II trials of its immunotherapy, PVX-108, for peanut allergy. “Our product is unlike other approaches that are in later stages of development, and those products generally use natural extracts from peanuts to treat peanut allergy,” Aravax CEO Pascal Hickey told BioWorld.
Eurocine Vaccines AB has reported findings from preclinical studies evaluating its mRNA and protein technology platforms for its therapeutic herpes simplex virus type 2 (HSV-2) vaccine candidates. Initial results from the study, comparing the two technology platforms at multiple doses, demonstrate that the mRNA and the protein vaccines were well tolerated and generated T-cell and antibody responses.
Dialing down the immune response remains at the heart of myriad drug development efforts in autoimmune disease. Targeting cytokines, such as tumor necrosis factor alpha or interleukin-12 (IL-12) and IL-23, IL-6, or IL-17, or modulating immune cell trafficking by targeting sphingosine-1-phosphate receptor or integrins, are therapeutic mainstays. But chronic immunosuppression and all its attendant safety concerns is the price that many autoimmune disease patients pay to remain in remission.
Jiangsu Recbio Technology Co. Ltd. has received clinical trial approval for its novel adjuvanted recombinant shingles vaccine, REC-610, from the Food and Drug Administration of the Philippines. A phase I trial will be conducted in healthy volunteers.
Research shows that microglia, macrophage cells found in the central nervous system, are needed to maintain nerve health by preventing the degeneration of the myelin sheath that protects neurons. The study, led by the University of Edinburgh and the University of Toronto and published on Dec. 14, 2022, in Nature, showed microglia could be a potential therapeutic target for neurological conditions involving myelin degeneration.
Alzheimer’s disease has a higher incidence in women. This sex difference was associated with a modification of certain proteins of the immune system. According to a recent study, the drop in estrogen with menopause increased the expression in the brain of a neurotransmitter, nitric oxide (NO), generating the S-nitrosylation of complement factor C3 (abbreviated SNO-C3), which activated the microglia.
Ovarian cancer is ordinarily associated with poor survival; patients diagnosed with high-grade serous ovarian carcinoma (HGSC) have an overall survival of about 40% at 5 years and 15% at 10 years. Despite having similar histologic features, HGSC patients often experience highly variable outcomes and the underlying determinants for long-term survival (LTS) are largely unknown. In a study published online in Nature Genetics, a multi-institutional group of researchers tried to determine the molecular differences that drive LTS in patients with HGSC.
