Ultraviolet Radiation Forecasting Based Heliotherapy For Psoriasis in Bangkok, Thailand

Study Purpose

Due to limited number of phototherapy centres and shortage of qualified phototherapy practitioners, heliotherapy has become a promising treatment alternative in Thailand where patients effortlessly receive supervised sun-bathing treatments from their homes whenever they are convenient. We used newly designed deep neural network UV forecasting model developed by using our 10 year-retrospective Solar UV irradiance (280-400 nm) retrieved from a ground based platform at Atmosperic laboratory, Silpakorn University, Nakhon Pathom, Thailand (13.82N 100.04E, 30 m above mean sea level). This model achieved a next-day forecast error of less than 12% which has been the most accurate prediction to date. We designed our 10week heliotherapy regimen based on the predicted anti psoriasis effective irradiance values. We studied efficacy and safety of the 12-week heliotherapy regimen for psoriasis on only ruled acceptable clear sky days in Bangkok, Thailand

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Yes
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT04740983
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
