The complete regimen combines the integrase strand transfer inhibitor (INSTI) cabotegravir, developed by ViiV Healthcare, with rilpivirine, a non-nucleoside reverse transcriptase inhibitor (NNRTI) developed by Janssen Sciences Ireland UC, part of the Janssen PharmaceuticalCompanies of Johnson & Johnson.

Tom Ireland writes about the companies and technologies that are reimagining phage therapy. Over time, this dynamic leads to many, slightly different strains of both virus and host. Read it on our website here. Illustration by David S. Goodsell, RCSB Protein Data Bank and Scripps Research.
21, 2021 /PRNewswire/ — The Janssen PharmaceuticalCompanies of Johnson & Johnson today announced the U.S. “While much more remains to be done to make HIV history, today’s milestone reminds us how far medical innovation has come since the first reported cases of the virus almost 40 years ago.”
In response, researchers and pharmaceuticalcompanies are exploring novel approaches to antibiotic development. Over the past two decades, many pharmaceuticalcompanies have deprioritized antibiotic research due to high development costs and lower profitability compared to treatments for chronic diseases.
DNA sequences are designed on a computer, and it takes a dozen or more clicks to change a single nucleotide. DNA sequences are also checked by hand, so it’s easy to make a mistake. The tool outputs a DNA sequence that encodes all the required enzymes. A phage is a virus that infects bacteria.

Then, during graduate school at the California Institute of Technology in the early 1960s, he was introduced to bacteriophage T7, a virus that infects Escherichia coli bacteria. If a gene was tagged with a special DNA sequence, known as the T7 promoter, then the T7 RNA polymerase would latch on and begin copying it.
mRNA was the intermediate stage between DNA and protein, a dynamic entity that shifted depending on the second-to-second needs of the cell, able to point out if a cell was cancerous or stressed, what kind of cell it was, and so on. Collections of mRNA have been understood as a proxy for cell states for decades.
Pharmaceuticalcompanies are, therefore, exploring innovative approaches. Their joint efforts have led to the development of gepotidacin , a novel first-in-class antibiotic that inhibits the bacterial enzymes topoisomerase II and DNA gyrase, which are essential for DNA replication and repair.
Approval is for Cytomegalovirus, a Type of Herpes Virus. Livtencity works by preventing the activity of human cytomegalovirus enzyme pUL97, thus blocking virus replication. CMV is a type of herpes virus that commonly causes infection in patients after a stem cell or organ transplant. Today, the U.S.
Some scientists even think it had a virus defense system; “researchers say LUCA likely housed 19 CRISPR genes, which bacteria use to slice up viral threats,” reports Quanta Magazine. DNA and RNA molecules are also built from exclusively right-handed nucleic acids.
In 2024, the pharmaceuticalcompany Gilead announced that a single injection of lenacapavir protected 96 to 100 percent of recipients from HIV for up to six months. Researcher Jerome Horwitz at the Michigan Cancer Foundation developed it as a potential cancer treatment by chemically-modifying thymine, a DNA building block.
