Brief Summary: The aim of this first-in-human phase I study is to assess the safety and tolerability of HAL-MRE1 subcutaneous immunotherapy in subjects suffering from ragweed pollen-induced allergic rhinitis/rhinoconjunctivitis with or without asthma.

The study has 4 treatment groups: 1 placebo group and 3 groups treated with different doses of HAL-MRE1.
Detailed Description: A chemically modified, aluminum hydroxide adsorbed ragweed extract (HAL-MRE1) for subcutaneous administration was developed for the treatment of ragweed pollen-induced allergic rhinitis/rhinoconjunctivitis (ARC) with or without asthma. The aim of this first-in-human phase I study is to assess the safety and tolerability of HAL-MRE1 subcutaneous immunotherapy in subjects suffering from ragweed pollen-induced ARC with or without asthma.

The study will consist of 3 staggered cohorts of 15 subjects each who are randomly assigned to the active or placebo group in a 2:1 manner using block randomization.

A one month gap must be maintained between the end of the ragweed pollen peak season (2018) and subject randomization into the study. The study has seasonal constraints; subjects with concomitant tree and/or grass pollen allergies must complete study treatment before any allergy symptoms due to tree and/or grass pollen exposure develop or start study treatment after the symptoms caused by the tree and/or grass pollen exposure have disappeared.
