Adverum Biotechnologies Inc (NASDAQ:ADVM) shares tumbled on Friday after the company announced it will not continue development of a gene therapy program to treat A1AT for liver or lung disease.

"While ADVM-043 was safely administered and was well tolerated, the preliminary protein expression unfortunately did not reach a level that justified moving the program forward with the current vector," said Leone Patterson, the CEO of Adverum.

The next step for the company is to conduct further studies "to determine the best candidates to advance forward in development for the rare disease programs. An update on the plan for these programs will be provided in the first half of 2019," Patterson said.

According to the US National Institute of Health, Alpha-1 antitrypsin deficiency is an inherited disease that causes an increased risk of having chronic obstructive pulmonary disease (COPD), liver disease, skin problems (panniculitis), and inflammation of the blood vessels. Lung problems almost always occur in adults, whereas liver and skin problems may occur in adults and children.

Shares of Adverum fell 42.4% to a session and 52-week low of $2.62 before recovering later in the session.
