A Phase 1/2 study of teclistamab, a humanized BCMA × CD3 bispecific Ab in Japanese patients with relapsed/refractory MM.

We characterized the safety and efficacy of the bispecific antibody teclistamab in Japanese patients with relapsed/refractory multiple myeloma (RRMM). Patients were pretreated with a proteasome inhibitor (PI), immunomodulatory drug (IMiD), and anti-CD38 monoclonal antibody (mAb). The primary endpoint was frequency and type of treatment-emergent adverse events (TEAEs) in phase 1, and overall response rate (ORR; ≥ partial response [PR]) in phase 2.

Evaluation of a novel severe combined immunodeficiency mouse model for antiviral drug evaluation against Chandipura virus infection.

Chandipura virus (CHPV) is a negative-sense single-stranded RNA virus known to cause fatal encephalitis outbreaks in the Indian subcontinent. The virus displays tropism towards the pediatric population and holds significant public health concerns. Currently, there is no specific, effective therapy for CHPV encephalitis.

Implications of the antiviral drug favipiravir on rabies immunoglobulin for post-exposure prophylaxis of rabies in mice model with category III-like exposures.

Rabies is a fatal zoonotic disease caused by the rabies virus (RABV), with almost 100% mortality if proper post-exposure prophylaxis (PEP), consisting of rabies immunoglobulin (RIG) and rabies vaccine, is not applied in a timely manner. However, this is challenged by the limited availability of RIG, especially in resource-constrained countries. In this study, we assessed the scope of the antiviral drug favipiravir to treat rabies-infected mice as an alternative to RIG.

Administration of the antiviral agent T-1105 fully protects pigs from foot-and-mouth disease infection.

Foot-and-mouth disease (FMD) is a contagious disease affecting cloven-hoofed animals. Its transmissibility and antigenic variety make this disease difficult to control. Antiviral agents are expected to have an immediate effect that is independent of viral antigenicity; thus, they can serve as effective tools for inhibiting the spread of the causative agent, the FMD virus (FMDV), from infected animals.

Susceptibility of Type I Interferon Receptor Knock-Out Mice to Heartland Bandavirus (HRTV) Infection and Efficacy of Favipiravir and Ribavirin in the Treatment of the Mice Infected with HRTV.

Heartland bandavirus (HRTV) is an emerging tick-borne virus that is distributed in the United States and that causes febrile illness with thrombocytopenia and leukocytopenia. It is genetically close to Dabie bandavirus, which is well known as severe fever with thrombocytopenia syndrome (SFTS) virus (SFTSV). The mortality rate of human HRTV infection is approximately 10%; however, neither approved anti-HRTV agents nor vaccines exist.
