Brief summary: This Phase I study is to investigate the safety of two dose levels of NFL-101 in smokers.

Detailed description: Tobacco addiction is one of the biggest public health threats the world has ever faced, killing nearly six million people a year. There are more than 1 billion smokers in the world, up to half will eventually die of a tobacco-related disease. Nicotine replacement treatments were the first pharmacological treatments approved for use in smoking cessation therapy and include nicotine gums, transdermal patches, tablets, nasal sprays, and inhalation systems. More recently, buproprion and varenicline were approved but showed limiting side effects. The development of safe and efficient alternatives for this indication is now called for.

Tobacco cessation cases were observed concomitantly with the administration of a desensitization treatment against tobacco allergy. Based on these observations, NFL Biosciences developed a drug candidate for tobacco cessation. This new drug (NFL 101) was assessed in preclinical studies. Notably, regulatory genotoxicity (Institut Pasteur de Lille) and toxicity studies in rats (Ricerca, Wil Research, Lyon) showed no toxicity. The NFL 101 composition and the low doses injected led to propose a mechanism of action based on an immune response. Immunogenicity studies conducted with the European Georges Pompidou Hospital (HEGP) on peripheral blood mononuclear cells and rodents have supported such hypotheses. Therefore, the objective of this Phase I study is to investigate the safety of two dose levels of NFL-101 in smokers.
