Human Immunodeficiency Virus (HIV) is the causative agent of Acquired Immunodeficiency Syndrome (AIDS) with high morbidity and mortality rates. Treatment of AIDS/HIV is being complicated by increasing resistance to currently used antiretroviral (ARV) drugs, mainly in low- and middle-income countries (LMICs) due to drug misuse, poor drug supply and poor treatment monitoring. However, progress has been made in the development of new ARV drugs, targeting different HIV components (Fig. 1). This review aims at presenting and discussing the progress made towards the discovery of new ARVs that are at different stages of clinical trials as of July 2024. For each compound, the mechanism of action, target biomolecule, genes associated with resistance, efficacy and safety, class, and phase of clinical trial are discussed. These compounds include analogues of nucleoside reverse transcriptase inhibitors (NRTIs) - islatravir and censavudine; non-nucleoside reverse transcriptase inhibitors (NNRTIs) - Rilpivirine, elsulfavirine and doravirine; integrase inhibitors namely cabotegravir and dolutegravir and chemokine coreceptors 5 and 2 (CC5/CCR2) antagonists for example cenicriviroc. Also, fostemsavir is being developed as an attachment inhibitor while lenacapavir, VH4004280 and VH4011499 are capsid inhibitors. Others are maturation inhibitors such as GSK-254, GSK3532795, GSK3739937, GSK2838232, and other compounds labelled as miscellaneous (do not belong to the classical groups of anti-HIV drugs or to the newer classes) such as obefazimod and BIT225. There is a considerable progress in the development of new anti-HIV drugs and the effort will continue since HIV infections has no cure or vaccine till now. Efforts are needed to reduce the toxicity of available drugs or discover new drugs with new classes which can delay the development of resistance.

Approved HIV reverse transcriptase inhibitors in the past decade

Review

Author: De Clercq, Erik ; Wang, Yali ; Li, Guangdi

HIV reverse transcriptase (RT) inhibitors are the important components of highly active antiretroviral therapies (HAARTs) for anti-HIV treatment and pre-exposure prophylaxis in clinical practice. Many RT inhibitors and their combination regimens have been approved in the past ten years, but a review on their drug discovery, pharmacology, and clinical efficacy is lacking. Here, we provide a comprehensive review of RT inhibitors (tenofovir alafenamide, rilpivirine, doravirine, dapivirine, azvudine and elsulfavirine) approved in the past decade, regarding their drug discovery, pharmacology, and clinical efficacy in randomized controlled trials. Novel RT inhibitors such as islatravir, MK-8504, MK-8507, MK8583, IQP-0528, and MIV-150 will be also highlighted. Future development may focus on the new generation of novel antiretroviral inhibitors with higher bioavailability, longer elimination half-life, more favorable side-effect profiles, fewer drug-drug interactions, and higher activities against circulating drug-resistant strains.

Biochemical profiling of anti-HIV prodrug Elsulfavirine (Elpida^®) and its active form VM1500A against a panel of twelve human carbonic anhydrase isoforms

Q2 · MEDICINE

ArticleOA

Author: Savchuk, Nikolay ; Krasavin, Mikhail ; Supuran, Claudiu T. ; Yakubova, Elena ; Nocentini, Alessio ; Kalinin, Stanislav

The non-nucleoside reverse transcriptase inhibitor VM1500A is approved for the treatment of HIV/AIDS in its N-acyl sulphonamide prodrug form elsulfavirine (Elpida^®). Biochemical profiling against twelve human carbonic anhydrase (CA, EC 4.2.1.1) isoforms showed that while elsulfavirine was a weak inhibitor of all isoforms, VM1500A potently and selectively inhibited human (h) hCA VII isoform, a proven target for the therapy of neuropathic pain. The latter is a common neurologic complication of HIV infection and we hypothesise that by using Elpida^® in patients may help alleviate this debilitating symptom.

Clinical Study Collaborator HCL Sends First Surgically Excised Ovarian Cancer Tumors to BioVaxys for BVX-0918 Vaccine Process Development

VANCOUVER, BC, June 15, 2022 /PRNewswire/ -- BioVaxys Technology Corp. (CSE: BIOV) (FRA: 5LB) (OTCQB: BVAXF) ("BioVaxys" or "Company"), announced today that its clinical study collaborator Hospices Civils de Lyon in France ("HCL") has surgically excised the first ovarian cancer tumors from cancer patients to be used by BioVaxys for process development and manufacturing "dry runs" of BVX-0918, a major step leading to the completion of Good Manufacturing Process ("GMP") production of the Company's ovarian cancer vaccine. BioVaxys recently entered collaborations with HCL and Deaconess Research Institute in the United States to provide the Company with surgically debulked tumors from Stage III/Stage IV ovarian cancer patients. Tumor samples from both hospitals are being used by BioVaxys' Lyon-based manufacturing partner, BioElpida ("BioElpida"), to validate the tumor collection protocol, cryopackaging, cryopreservation, and supply chain logistics for BVX-0918 bioproduction for prospective patients in the US and EU. Donors of ovarian cancer tumors are required to sign a patient consent form, with the tumor extraction, storage, and shipping logistics following a strict protocol developed by Biovaxys, and subjected to institutional and regulatory approval. BVX-0918 produced from the surgically removed tumor cells from HCL will be screened using the identity assays derived from the OVCAR-3 cell line recently completed by BioElpida. The identity assay will be performed on every batch of autologous ovarian cancer vaccine, and is mandatory for regulatory bodies in the EU and United States. BioVaxys President and Chief Operating Officer Kenneth Kovan stated that, "The production of BVX-0918 is a process that built on the prior successful execution of sequential steps, such as the bioproduction technology transfer to BioElpida, development of validation procedures needed to support GMP manufacturing, sterility testing for transport, hapten fixation, cryopreservation methods, antibody generation, bioburden screening, endotoxin assays, and most recently, the development of the identity assays from the OVCAR-3 cell line. With the surgically excised tumors we can now begin the final stages of the vaccine production protocol and GMP validation." BioVaxys' vaccine platform is based on the established immunological concept that modifying surface proteins---whether they are viral or tumor---with haptens makes them more visible to the immune system. This process of haptenization "teaches" a patient's immune system to recognize and make target proteins more "visible" as foreign, thereby stimulating a T-cell mediated immune response. BioVaxys' cancer vaccines are created by extracting a patient's own (autologous) cancer cells, chemically linking with a hapten, and re-injecting them into the patient to induce an immune response to proteins which are otherwise not immunogenic. Haptenization is a well-known and well-studied immunotherapeutic approach to cancer immunotherapy and has been clinically evaluated in both regional and disseminated metastatic tumors. A first generation single-hapten vaccine invented by BioVaxys Co-Founder and Chief Medical Officer David Berd, MD, achieved positive immunological and clinical results in Phase I and Phase II human trials in over 600 patients with different tumor types, as well as having no observed toxicity in years of clinical study. These studies were conducted under an FDA-reviewed IND. A first generation autologous, haptenized vaccine was also tested by Dr. Berd in women with advanced ovarian cancer who had ceased to respond to conventional chemotherapy. The results were encouraging: In 24 patients, the median overall survival was 25.4 months with a range of 4.5-57.4 months; 8 patients survived for more than 2 years. BioVaxys has enhanced the first-generation approach by utilizing two haptens ("bi-haptenization"), which the Company believes will yield superior results. About BioVaxys Technology Corp. Based in Vancouver, BioVaxys Technology Corp. () is a British Columbia-registered, clinical stage biotechnology company that is developing viral and oncology vaccine platforms, as well as immuno-diagnostics. The Company is advancing vaccines for SARS-CoV-2, SARS-CoV-1, and a pan-sarbecovirus vaccine based on its haptenized viral protein technology, and is planning a clinical trial of its haptenized autologous cell vaccine used in combination with anti-PD1 and anti-PDL1 checkpoint inhibitors that will initially be developed for Stage III/Stage IV ovarian cancer. Also in development is CoviDTH®, a diagnostic for evaluating the presence or absence of a T cell immune response to SARS-CoV-2, the virus that causes COVID-19. BioVaxys has two issued US patents, and multiple US and international patent applications related to its cancer vaccines, antiviral vaccines, and diagnostic technologies. BioVaxys common shares are listed on the CSE under the stock symbol "BIOV" and trade on the Frankfurt Bourse (FRA: 5LB) and in the US (OTCQB: BVAXF).
