Oral Immunotherapy for Peanut Allergic Patients

Study Purpose

Multicenter, double-blind, randomized, placebo-controlled phase I/II study to determine the safety, tolerability, potential efficacy and dose finding of INP20, an oral immunotherapy in peanut-allergic patients. The overall study design consists of two sequential periods of Part A and Part B. Part A is a dose escalation study in patients from 12 to 65 years old with a history of immediate hypersensitive reaction to peanut protein. Six diferent oral-dose of INP20 will be administered to 6 cohorts of patients once daily for 2 weeks. Part B is a 6-month double-blind, placebo-controlled, randomized and parallel groups study. Patients will be randomized in a 1:1:1 ratio into three

  • (3) different treatment groups, including placebo and the two doses of peanut protein selected from Part A.
They will recieve INP20 once daily for 6 months.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT04163562
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
