Information sheet PRA-176761

Type of study

The purpose of this study is to investigate the influence of the study medication on the absorption, distribution, and elimination (this is called pharmacokinetics) of Methotrexate from the body. The study medication has been administered to humans before. Methotrexate is not a new compound, it is already available on the market in several dosages and formulations. It will also be investigated whether Methotrexate given without and with the study medication is safe. This study is not intended to improve your health, but is necessary for the further development of this study medication.

In autoimmune diseases the immune system does not only react to foreign substances, as it should, but also to parts of the body. This results in inflammatory reactions in the joints (RA), skin (psoriasis), or the bowel. The study medication blocks an enzyme (tyrosine kinase 2) which has a role in the immune response and should decrease the immune response to parts of the body. Methotrexate has been on the market for more than 50 years as a drug for the treatment of RA, psoriasis, and some types of cancer. To prevent potential side effects of Methotrexate as much as possible, leucovorin (calcium folinate) will be given 24 hours after the administration of Methotrexate. Leucovorin is a drug used to block part of the activity of Methotrexate thus reducing the risk for side effects.

The study will only take place after it has been approved by the Independent Ethics Committee.

Setup and duration of the study

The study consists of 1 period were you will stay for 20 days (19 nights) in our research facility in Groningen (location UMCG). The study medication will be given as oral capsules, Methotrexate as tablets and Leucovorin as capsules. Before the start of the study you will visit the medical screening centre. Blood samples will be taken regularly during the study.

Risks and medical supervision

All drugs have the potential to cause adverse events. You should be aware that unknown adverse effects may occur during the study. The study medication is a so-called kinase inhibitor. Acne is a side-effect of many drugs with a similar mechanism of action. The same is true for the study medication. Acne can occur from the second day of treatment onwards on typical places like the face and chest, but other parts of the body may also be affected. In general, the skin abnormalities resolve spontaneously when the drug is discontinued. In most cases the acne is treated with a cream. Other types of skin rashes, including urticaria, were occasionally observed.

In general, tolerability of Methotrexate as a single dose in healthy volunteers is excellent. As a precaution against possible side effects, you will get a dose of Leucovorin 24 hours after the administration of Methotrexate. Leucovorin is used as an antidote, a compound countering the side effects of other compounds, like for Methotrexate. Sometimes, in less than 1 in 100 people, Leucovorin can cause fever.

Before the study and at the end of the study you will undergo an extensive medical screening.

Conditions for participation

You are a healthy male between 18 and 50 years old. Your Body Mass Index (BMI) is between 18.0 and 32.0 kg/m2 (the BMI reflects the relation between your body weight in kilograms and your height in meters). You can only take part in the study if you do not smoke.

The study will be executed under standardized conditions. Use of your own medication, alcohol, regular coffee and tea, cola, power drinks, chocolate (including products made of chocolate), grapefruit (juice) and tobacco products during the study is not allowed. Also before the study and during each period there will be restrictions for these products. Use of decaffeinated coffee and (herbal) teas without caffeine (also mentioned theine) is allowed. Before you are allowed to take part in the study, you will be medically screened. The screening will take place within four weeks before the start of the study.
