The present invention concerns methods and compositions for treatment of HIV infection in a subject, utilizing a DNL® complex comprising at least one anti-HIV therapeutic agent, attached to an antibody, antibody fragment or PEG. In a preferred embodiment, the antibody or fragment binds to an antigen selected from gp120, gp41, CD4 and CCR5. In a more preferred embodiment the antibody is P4/D10 or 2G12, although other anti-HIV antibodies are known and may be utilized. In a most preferred embodiment, the anti-HIV therapeutic agent is a fusion inhibitor, such as T20, T61, T651, T1249, T2635, CP32M or T-1444, although other anti-HIV therapeutic agents are known and may be utilized. The DNL® complex may be administered alone or may be co-administered with one or more additional anti-HIV therapeutic agents.

The present invention relates to multispecific antibodies, methods for their production, pharmaceutical compositions containing said antibodies and uses thereof.

The present invention generally relates to T cell activating bispecific antigen binding molecules, PD-1 axis binding antagonists, and in particular to combination therapies employing such T cell activating bispecific antigen binding molecules and PD-1 axis binding antagonists, and their use of these combination therapies for the treatment of cancer.

The present invention relates to peptides that bind with high specificity and which functionally interact with the transferrin receptor (“TfR”) and which may be used in making molecular vehicles that carry biomolecules across membranes, including, e.g., across the blood brain barrier or the gastrointestinal tract. TfR specific binding moieties may also be used alone or as components in specific molecules that target the transferrin/transferrin receptor transport system. The invention relates more specifically to VNAR single chain antibodies derived from nurse shark that bind to TfR, compounds and compositions comprising a TfR specific VNAR binding moiety, methods for preparing them, diagnostic and therapeutic methods of use in vitro or in vivo, e.g., to diagnose, treat and/or prevent a pathological condition, disorder or disease in which it is beneficial to deliver a heterologous biomolecule across the blood brain barrier by association with a TfR specific VNAR binding moiety. Other uses for TfR specific VNAR binding moieties of the invention include, e.g., regulating the interaction of iron-charged transferrin with TfR (receptor cycling or cell surface presentation), such as may be therapeutic in treatment of certain cancer cells and tumors of various tissue types.

The present invention is directed to methods of administrating bispecific anti-CD20×anti-CD3 antibodies.

The present invention relates to the fields of molecular medicine and targeted delivery of therapeutic or diagnostic agents to cells outside the vascular system and into the parenchymal tissue of organs within the body. More specifically, the present invention relates to improved TfR-binding moieties based on shark VNARs capable of crossing the blood brain barrier (BBB) and capable of carrying and releasing cargo specifically targeted to the parenchymal tissue of the brain.

The invention relates to a bispecific antibody targeting TfR1 and a soluble antigen. The inventors demonstrate that the unique mode of interaction of the bispecific antibody with TfR1 increases its persistence in vivo through an FcRn-like mechanism. It has been demonstrated on MCF7 cell line that the bispecific antibody induces soluble antigen (IL6) uptake through TfR1 mediated endocytosis. Effects of the bispecific antibody on XG6 cell lines viability have been demonstrated, notably on iron and IL-6 deprivation. Hence, the inventors design an improved sweeping antibody which can specifically target tumors and inflammatory cells expressing TfR1. By its unique mode of interaction with TfR1, its ability to induce soluble uptake antigen through TfR1 mediated endocytosis and its capacity to deprive cells of iron, known for being required in tumors growth and progression and development of inflammatory pathologies, the bispecific antibody can be used in the treatment of cancer and inflammatory pathologies.

The present invention relates in part to amino acid sequences that are directed against and/or that can specifically bind to an envelope protein of a virus, as well as to compounds or constructs, and in particular proteins and polypeptides, that comprise or essentially consist of one or more such amino acid sequences.

Disclosed herein are multispecific antibodies comprising a CD38 binding domain and an BCMA binding domain. Further provided herein are methods of treating cancer comprising administering to a subject having cancer a pharmaceutical composition comprising a multispecific antibody comprising a CD38 binding domain and an BCMA binding domain.

The present disclosure relates to activatable anti-EGFR, anti-CD3, heteromultimeric bispecific polypeptide complexes (HBPCs) and methods of making and using the same.
