Synergistic in vitro antiretroviral activity of a humanized monoclonal anti-CD4 antibody (TNX-355) and enfuvirtide (T-20).

چکیده
Recently, antiretroviral agents directed at several steps involved in viral entry have been shown to reduce viral replication in vitro and in vivo. We have demonstrated a high level of in vitro synergistic antiretroviral activity for two entry inhibitors that are directed at sequential steps in the entry process.

Antiretroviral activity of the anti-CD4 monoclonal antibody TNX-355 in patients infected with HIV type 1.
BACKGROUND We wished to determine the safety and anti-human immunodeficiency virus (HIV) type 1 activity of single doses of TNX-355, a humanized IgG4 anti-CD4 monoclonal antibody with potent activity against HIV-1 in vitro, in HIV-infected subjects. METHODS Sequential cohorts of 6 HIV-1-infected subjects each received infusions of TNX-355. Data included plasma HIV-1 RNA level, CD4+ T cell cou...

Ibalizumab (formerly TNX-355) is a humanized monoclonal antibody that binds CD4, the primary receptor for human immunodeficiency virus type 1 (HIV-1), and inhibits the viral entry process. A phase lb multidose study of the safety, pharmacokinetics, and antiviral activity of ibalizumab was conducted with 22 HIV-1-infected patients. Nineteen patients were randomized to receive either 10 mg/kg of ...

Background: The induction chemotherapy regimen for acute myeloid leukemia has evolved as once induction is completed patients progress through the consolidation phase and achieve remission in 76% of cases. For patients with relapsed or refractory disease, alternative chemotherapy agents are available. Monoclonal antibody therapy with biological agents, such as the immunotoxin gemtuzumab ozog...
متن کاملFavorable interactions between enfuvirtide and 1-beta-D-2,6-diaminopurine dioxolane in vitro.
We evaluated the in vitro anti-human immunodeficiency virus type 1 (HIV-1) interactions between 1-beta-D-2,6-diaminopurine dioxolane (DAPD) and enfuvirtide (T-20) against clinical isolates sensitive and resistant to reverse transcriptase and protease inhibitors. Interactions between T-20 and DAPD were synergistic to nearly additive, with combination index values ranging from 0.53 to 1.06 at 95%...
متن کاملDesign of a humanized anti vascular endothelial growth factor nanobody and evaluation of its in vitro function
Objective(s): Nanobodies, the single domain antigen binding fragments of heavy chain-only antibodies occurring naturally in camelid sera, are the smallest intact antigen binding entities. Their minimal size assists in reaching otherwise largely inaccessible regions of antigens. However, their camelid origin raises a possible concern of immunogenicity when used for human therapy. Humanization is...
