About
HM71224 is a potent small molecule inhibitor of Bruton's tyrosine kinase (BTK). BTK is a member of the Tec family of non-receptor protein tyrosine kinases. BTK is mostly expressed in hematopoietic cells such as B cells, mast cells and macrophages. BTK plays key roles in multiple cell signaling pathways including B-Cell Receptor (BCR) and Fc receptor (FcR) signaling cascades and is an essential mediator not only in B-cell dependent but also in myeloid cell dependent inflammatory arthritis. HM71224 has been selected as a novel therapeutic agent for the treatment of autoimmune diseases such as rheumatoid arthritis (RA).
In view of the above, further development of HM71224 for the treatment of RA is warranted. In this first-in-man (FIM) study, a single and multiple dose escalation design will be employed, in which the primary objective is to evaluate the safety and tolerability of the compound. The biomarkers included as pharmacodynamic (PD) variables are chosen as they are indicators for any effects of HM71224 on the expected mode of action (pBTK, pPLCγ, and pERK).
Full description
Primary objective
To evaluate the safety and tolerability, and if possible maximum tolerated dose (MTD) of HM71224 after single and multiple ascending dose administration in healthy subjects.
Secondary objective
To determine the PK of HM71224 and selected metabolites (M1 and M2) following single and multiple oral dose administration of HM71224. To assess the PD effects of HM71224 on the biomarkers pBTK, pPLCγ, and pERK. To assess whether the PK of HM71224 is affected by food.

- Use of concomitant medication, except for acetaminophen (paracetamol), which is allowed up to 3 days before entry into the clinical research center. Multivitamins and vitamin C are allowed up to 7 days before entry into the clinical research center. All other medication (including over the counter medication, health supplements, and herbal remedies such as St. John's Wort extract) must have been stopped at least 14 days prior to entry into the clinical research center. The use of a limited amount of acetaminophen during the study is permitted.

- Donation of more than 50 mL of blood within 60 days prior to drug administration. Donation of more than 1.5 liters of blood in the 10 months preceding the start of this study (this is the first administration of study drug).
- Positive drug screen (opiates, methadone, cocaine, amphetamines, cannabinoids, barbiturates, benzodiazepines, and alcohol)
- Intake of more than 24 units of alcohol per week (one unit of alcohol equals approximately 250 mL of beer, 100 mL of wine or 35 mL of spirits)
- Positive screen on Hepatitis B Surface Antigen (HBsAg), anti-Hepatitis C Virus (HCV) or anti-Human Immunodeficiency Virus (HIV) 1/2
