Benefits of technology

[0017]In related embodiments, the invention provides for methods to reduce the dependence on TCS in a patient with moderate-to-severe AD comprising concomitant administration of an IL-4R antagonist and a TCS, wherein the dosage of the TCS is reduced by 50% as compared to subjects without the administration of the IL-4R antagonist. In one embodiment, the invention provides methods to reduce the dosage of a TCS in treatment of moderate-to-severe AD, comprising administration of an IL-4R antagonist concomitantly with a reduced dosage of the TCS. The dosage of the TCS may be reduced by more than, for example, 10%, 20%, 30%, 40%, or 50%. In one embodiment, the dosage of the TCS may be reduced by more than, for example, 10%, 20%, 30%, 40%, or 50% as compared to the dosage used by the subject before treatment with the IL-4R antagonist.

Problems solved by technology

Severe disease can be extremely disabling due to major psychological problems, significant sleep loss, and impaired quality of life, leading to high socioeconomic costs.
Most treatment options, however, offer only temporary, incomplete, symptom relief.

n of Human Antibodies to Human IL-4R

[0223]Human anti-hIL-4R antibodies were generated as described in U.S. Pat. No. 7,608,693. Table 1 sets forth the sequence identifiers for the heavy and light chain variable region amino acid sequence pairs, and CDR amino acid sequences, of selected anti-IL-4R antibodies and their corresponding antibody designations.

cending Dose Clinical Trial of Intravenously and Subcutaneously Administered Anti-IL-4R Antibody (mAb1) in Healthy Subjects

A. Study Design

[0225]This study was a randomized, double-blind, placebo-controlled, sequential, single ascending-dose study of intravenous (IV) and subcutaneous (SC) administered mAb1 in healthy subjects. The main purpose of this study was to evaluate the safety and tolerability of intravenously and subcutaneously administered mAb1 in healthy subjects.

[0226]Screening occurred from day −21 to day −3. On day 1 (baseline), subjects were randomized to receive either IV or SC study drug (mAb1 or placebo) infused over a 2-hour period. Subjects returned on days 4, 8, 11, 15, 22, 29, 43, 57 and 85 (end-of-study) for safety assessments and blood sampling for clinical laboratory testing.

[0227]Forty-eight total subjects participated in the study. Four sequential ascending dose cohorts (1.0, 3.0, 8.0, and 12.0 mg / kg) were planned for IV dosing and 2 sequential ascending dos...

Trial of Two Different Drug Products of Anti-IL-4R Antibody (mAb1) Following Subcutaneous Administration of Anti-IL-4R Antibody (mAb1) in Healthy Patients

A. Study Design

[0238]This study was a single-center, single-dose, double-blind, randomized, no placebo-controlled study to assess the safety and pharmacokinetic profile of subcutaneous administration of two different anti-IL-4R mAb (mAb1) drug products generated from different cell lines and manufacturing processes. The drug products were provided in 150 mg / mL 2 mL doses, and 300 mg (2 mL) were administered subcutaneously to 30 healthy adults in two parallel groups (15 subjects per group). Subjects included 30 subjects represented by 22 males (73.3%) and 8 females (26.7%) aged 19 to 45 years old, with weights ranging from 54.8 to 94.3 kg.

[0239]Serum concentration of mAb1 was used to determine the following PK parameters: maximum serum concentration (Cmax), area under the [serum concentration versus time] curve from time 0 to the re...
