State of the Art: Development of a Sublingual Allergy Immunotherapy Tablet for Allergic Rhinitis in Japan.

Allergic rhinitis (AR) caused by house dust mite (HDM) and Japanese cedar pollen (JCP) represents a significant, expanding health problem in Japan. Allergic symptoms often have a severe impact on the QOL such as sleep disturbance and reduced school and work performance. In addition to the classical symptoms, AR is known to be a risk factor for the development of allergic asthma, a potentially life-threatening condition.

Efficacy and Safety of HDM SLIT Tablet in Japanese Adults with Allergic Asthma.

Background: The standardized quality (SQ) house dust mite (HDM) sublingual immunotherapy (SLIT) tablet has demonstrated efficacy and safety for allergic asthma (AA) in European trials.

Objective: To evaluate the efficacy and safety of SQ HDM SLIT tablet treatment for up to 19 months in Japanese adults with AA.

Methods: In this randomized, double-blind, placebo-controlled trial, patients aged 18 to 64 years with AA were randomly assigned (1:1:1) to SQ HDM SLIT doses of 10,000 or 20,000 Japanese Allergy Unit or placebo.

Safety profile of the SQ house dust mite sublingual immunotherapy-tablet in Japanese adult patients with house dust mite-induced allergic asthma: a randomized, double-blind, placebo-controlled phase I study.

The SQ house dust mite (HDM) sublingual immunotherapy (SLIT)-tablet has demonstrated effective treatment of HDM-induced allergic asthma in patients 18 years or older in European trials. This study investigated its safety and immunology profile in Japanese adult patients with mild-to-moderate HDM-induced allergic asthma. In this randomized, double-blind, placebo-controlled study, 48 Japanese patients were randomly assigned to a daily treatment of SQ HDM SLIT-tablet or placebo (3:1) for 14 d with or without an up-dosing regimen.

Efficacy and safety of SQ house dust mite sublingual immunotherapy-tablet in Japanese children.

Background: The SQ house dust mite (HDM) sublingual immunotherapy (SLIT)-tablet (TO-203, Torii, Japan/ALK, Denmark) treatment has been effective against respiratory allergic diseases in patients aged ≥12 years during European, Japanese, and North American trials. This trial was conducted to investigate the efficacy and safety of this treatment in Japanese children (5-17 years) with moderate-to-severe HDM allergic rhinitis (AR).

Methods: In this randomized, double-blind, placebo-controlled trial, 458 Japanese children were randomly assigned to a daily SQ HDM SLIT-tablet [10 000 Japanese Allergy Unit (JAU), equivalent to 6 SQ-HDM in Europe and the US] or placebo (1:1) treatment for 1 year.

Effects of Milk or Apple Juice Ingestion on the Pharmacokinetics of Elvitegravir and Cobicistat in Healthy Japanese Male Volunteers: A Randomized, Single-Dose, Three-Way Crossover Study.

Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (EVG/COBI/FTC/TAF) is specified in its package insert to be taken with food to obtain sufficient exposure of EVG. It has been reported that a nutritional protein-rich drink shows comparable pharmacokinetics (PK) of EVG to those with a standard breakfast. In this study, the PK profiles of EVG and COBI were evaluated by administration of a single dose of EVG/COBI/FTC/TAF, after ingestion of either a nutritional protein-rich drink, milk, or apple juice.
