VH3810109 Efficacy, Safety, Pharmacokinetics, and Incidence of Anti-drug Antibodies in Adults With HIV-1 Naive to Antiretroviral Therapy: BANNER Study Results.

Background: VH3810109 (N6LS) is a CD4-binding site antibody with broad and potent neutralizing activity in vitro. Here, we present efficacy, safety, and pharmacokinetic results from the phase 2a BANNER study in people with HIV-1.

Methods: BANNER was a randomized, open-label, 2-part, multicenter study of N6LS in adults naive to antiretroviral therapy (ART) with HIV-1 RNA ≥5000 copies/mL.

Longitudinal Innate and Heterologous Adaptive Immune Responses to SARS-CoV-2 JN.1 in Transplant Recipients With Prior Omicron Infection: Limited Neutralization but Robust CD4 T-Cell Activity.

Background: Solid organ transplant (SOT) recipients are at increased risk for severe COVID-19 and often exhibit reduced vaccine efficacy due to chronic immunosuppression. As new SARS-CoV-2 variants emerge, understanding immune responses following natural infection remains critical for informing protection strategies in this vulnerable population. We conducted a longitudinal study of SOT recipients who had recovered from Omicron BA.

BRCA1 polymorphism in breast cancer patients from Argentina.

Breast cancer is the most common type of cancer in females in Argentina, with an incidence rate similar to that in the USA. However, the contribution of the BRCA1 or BRCA2 mutation in breast cancer incidence has not yet been investigated in Argentina. In order to evaluate which BRCA1 polymorphisms or mutations characterize female breast cancer in Argentina, the current study enrolled 206 females with breast cancer from several hospitals from the southeast of Argentina.

Heme oxygenase-1 has antitumoral effects in colorectal cancer: involvement of p53.

The expression of heme oxygenase-1 (HO-1) has been shown to be up-regulated in colorectal cancer (CRC), but the role it plays in this cancer type has not yet been addressed. The aims of this study have been to analyze HO-1 expression in human invasive CRC, evaluate its correlation with clinical and histo-pathological parameters and to investigate the mechanisms through which the enzyme influences tumor progression. We confirmed that HO-1 was over-expressed in human invasive CRC and found that the expression of the enzyme was associated with a longer overall survival time.

Low activity of 13-cis-retinoic acid plus interferon alpha 2a in advanced renal cell carcinoma.

Retinoids and interferon alpha have shown synergistic activity against metastatic renal cell carcinoma in previous preclinical and clinical studies. Based on these results, we conducted a phase II trial of 13-cis-retinoic acid (cRA) at 1 mg/kg/dose interferon alpha2a (IFN) at initial dose of 9 MU three times a week. Thirty-one patients were entered, all evaluable for toxicity and 30 evaluable for response.
