For Jeff Galvin, the CEO and founder of newly launched Addimmune Inc., HIV is not a condition that’s in the rearview mirror. It needs a functional cure to save lives, make people healthier and save money that need not have been spent. People wonder why it’s worth bothering to cure HIV, Galvin told BioWorld, when they are taking their medications every day and they are feeling pretty close to normal. But it’s not close for Galvin, who noted that there are side effects from taking the pills that can cause headaches, fatigue, nausea and diarrhea.
Aegis Life Inc. and its parent company Entos Pharmaceuticals Inc. (Entos) have entered into a grant agreement with the Bill & Melinda Gates Foundation in the area of infectious disease.
The HIV-1 envelope glycoprotein (Env) mediates cell entry and is the target of the host humoral immune response. Functional Env is a trimer of noncovalent gp120-gp41 heterodimers. Rational trimer design has transformed the HIV-1 vaccine research field and has helped understand Env structure and immunogenicity. Uncleaved prefusion-optimized (UFO) trimers have been shown to stabilize diverse HIV-1 Env glycoproteins.
The U.S. government’s attempts to enforce its ownership of biopharma intellectual property got a setback May 9 when a six-member federal jury in Delaware determined that Gilead Sciences Inc. did not infringe government patents claiming pre-exposure prophylaxis (PrEP) use of Gilead’s HIV drugs, Truvada and Descovy, both of which combine emtricitabine and tenofovir.
Merck Sharp & Dohme Corp. researchers have patented targeted activator of cell kill (TACK) compounds acting as Gag polyprotein (HIV-1)/protein Pol dimerization inducers and thus reported to be useful for the treatment of HIV infection.
The success of the President’s Emergency Plan for AIDS Relief (PEPFAR) over the past 20 years is one of the biggest challenges in reaching its goal of eliminating HIV as a global public health threat by 2030, members of the U.S. Senate Foreign Relations Committee were told as they moved toward reauthorizing the program for another five years.
Although COVID-19 may be more severe in people with HIV (PWH), the underlying biological mechanisms among PWH treated with antiretroviral therapy (ART) remain largely unknown.
HIV infects immune cells, mainly CD4+ T cells. But they are not the only ones. It also settles in the genome of myeloid cells, monocytes or macrophages. According to a study from Johns Hopkins University, the viral DNA inserted into myeloid cells is functional. The virus also reactivated from the monocyte-derived macrophage reservoir. New cure strategies need to take these cells into account to eradicate the virus from the body.
