Summary

The results of phase I Namisol® study (Klumpers et al. Br J Clin Pharmacol, 2012), implicate that Namisol® may have a favorable PK and PD characteristics and is safe to use in people. However, the study included only young adults with a mean age of 21.4 years. In a previous THC study, subjects age has been associated with treatment response and tolerance of adverse reactions. This association was not supported by Lane et al. and Volicer et al.

There is concern about the safety and tolerability of THC in the elderly population. This is because, elderly persons in general have higher risk of adverse drug reactions due to a combination of physiological factors such as decreasing in lean body mass, the reduction of renal and hepatic clearance, and medical comorbidity which can lead to polypharmacy and drug-drug interactions. Therefore, data from the phase I trial cannot be translated directly to an elderly (and likely more vulnerable) population. This makes it important to evaluate the safety and tolerability profiles of different Namisol® doses in the elderly. In our study in progress "Delta-THC in Behavioral Disturbances in Dementia", the Namisol® doses of 0,75 mg and 1,5 mg are, until now, well tolerated by elderly subjects. These doses are, however, very low in comparison with the doses used in phase I study with young adults (5 mg, 6,5 mg and 8 mg). The current study on the safety and tolerability of relatively high doses of Namisol® will help us in the future to provide broad advice on the therapeutic index and safety profile of Namisol® in the elderly population.

Conditions

  • Drug Safety

Interventions

DRUG

delta-9-tetrahydrocannabinol

During the intervention phases, subjects will be randomly allocated to receive 1 of 3 doses Namisol®: 3 mg, 5 mg, 6,5 mg (or placebo) The washout period between the intervention periods will be at least 2 weeks.

DRUG

Placebo

On each intervention day the subjects will receive the same amount of drugs in order to insure the blinding of the study
