Systems toxicology assessment of CHTP1.2 [Liver Data]


ABSTRACT: Modified risk tobacco products (MRTPs) have the potential to reduce smoking-related health risks. The Carbon Heated Tobacco Product 1.2 (CHTP1.2) is a potential MRTP that uses a pressed carbon heat source to generate an aerosol by heating tobacco. This study reports the results from the systems toxicology arm of a 90-day rat inhalation study (OECD test guideline 413) to assess the effects of CHTP1.2 aerosol compared with cigarette smoke (CS). Rats were exposed to filtered air (sham), to CHTP1.2 aerosol (at 15, 23 and 50 µg nicotine / L), or to the 3R4F reference cigarette smoke (at 23 µg nicotine / L).
