Abstract: Provided herein is a platform technology for the generation of properly paired bispecific antibodies. Some of the antibodies generated have Fc region modifications, in particular in their CH3 domains by lysine repositioning to drive heterodimerization of the two heavy chains of the bispecific antibody. Some of the antibodies generated have Fab arm modifications to prevent mispairing of light chains. Specifically, the CH1 and CL domains of one of the Fab arms of the bispecific antibody are substituted with an IgE CH2 domain or an IgM CH2 domain.

Abstract: A combination and method for treating multiple sclerosis (MS), and for reducing flu-like symptoms associated with administration of an interferon to a patient with MS. The method involves intramuscularly administering the interferon to the MS patient according to an escalating dosing regimen in weeks 1 to 3, and a full therapeutically effective dose of interferon in week 4. In one embodiment of the invention, the escalating dosing regimen comprises administering one quarter of the therapeutically effective dose in week 1, half of the therapeutically effective dose in week 2, and three-quarters of the therapeutically effective dose in week 3. Also provided are titration packages for enabling compliance with a regimen of changing dosage of an interferon over a period of time.

Abstract: A brain volume (BV) calculation method includes obtaining a first set of medical images at a first time point and a second set of medical images at a second time point, each set including at least two medical images. First and second algorithms may be used to calculate, respectively, first and third BV values at the first time point based on two or more images from the first set of medical images, and second and fourth BV values at the second time point based on two or more images from the second set of medical images. A mathematical weight may be applied to at least one of the first to fourth BV values. The first and third BV values may be averaged, and the second and fourth BV values may be averaged to determine overall BV values at the first and second time points, respectively.

Abstract: Natalizumab is a safe and efficacious treatment for inflammatory and autoimmune diseases, such as multiple sclerosis, Crohn's Disease, and rheumatoid arthritis. Chain swapping between natalizumab and IgG4 molecules acts to reduce the level of bivalent natalizumab present following administration of natalizumab, and thus to lower the activity of natalizumab in the patient. Differences in IgG4 levels across patients or within a single patient across time may change the pharmacokinetic profile of natalizumab. Patients with lower levels of IgG4 may experience higher nadir levels of natalizumab during a dosing period. Monitoring IgG4 and/or bivalent natalizumab levels, and determining a dose or dosage period based on the monitoring may improve the safety and/or efficacy of natalizumab therapy.

The present disclosure further provides pharmaceutical compositions, kits, and methods of use, each of which involve the compounds. The compounds, pharmaceutical compositions, and kits may be useful for treating diseases associated with aberrant activity of GSK3a (e.g., Fragile X syndrome, attention deficit hyperactivity disorder (ADHD), childhood seizure, intellectual disability, diabetes, acute myeloid leukemia (AML), autism, and psychiatric disorder).

Abstract: The present disclosure describes novel hybrid soluble ActRIIB-ECD polypeptides which fully retain binding affinity for myostatin and activin A but demonstrate significantly reduced binding to BMPs, especially BMP-9. The novel compositions described herein can be used to prepare novel hybrid ActRIIB ligand trap proteins, which can be used for modulating the growth of muscle, bone, cartilage, fat, fibroblast, blood and neuronal tissue to counteract muscle wasting, bone loss, anemia, inflammation and fibrosis in a therapeutically meaningful manner. Because these novel next-generation myostatin/activin inhibitors are safer and more effective molecules than the currently available myostatin inhibitors, they are useful in a wide variety of clinical indications.

Abstract: Natalizumab is a safe and efficacious treatment for inflammatory and autoimmune diseases, such as multiple sclerosis, Crohn's Disease, and rheumatoid arthritis. Rare occurrences of progressive multifocal leucoencephalopathy during treatment suggest the possibility that it may be related to natalizumab treatment. Monitoring for JCV and informing caregivers and patients about the manifestations of progressive multifocal leucoencephalopathy can improve the safety of natalizumab therapy.

Abstract: The disclosure relates to methods and reagents for analyzing samples for the presence of JC virus antibodies. Disclosed is a method that includes obtaining a biological sample from a subject (e.g., plasma, serum, blood, urine, or cerebrospinal fluid), contacting the sample with highly purified viral-like particles (HPVLPs) under conditions suitable for binding of a JCV antibody in the sample to an HPVLP, and detecting the level of JCV antibody binding in the sample to HPVLP. In one embodiment, determining the level of anti-JCV antibodies in the subject sample provides a method of identifying PML risk in a subject.

Abstract: Antibodies and antigen-binding antibody fragments that bind to GPIIb/IIIa and chimeric polypeptides comprising these binding molecules are disclosed. Some of these antibodies and antigen-binding antibody fragments preferentially bind GPIIb/IIIa on activated platelets while others do not show a preference for binding GPIIb/IIIa on resting versus activated platelets. Some of these antibodies and antibody fragments do not inhibit the interaction of GPIIb/IIIa with fibrinogen, while some others do. The disclosed antibodies do not induce platelet activation. Some of these antibodies and antigen-binding antibody fragments are useful in targeting therapeutic agents such as dotting factors to platelets while others are useful in reducing platelet aggregation and/or thrombus formation.
