Inclusion criteria

* Body mass index (BMI) in the range of 18.5 to 35 kg/m2 (inclusive) at screening. * Good mental health in the opinion of the investigator. * Normal spirometry (FEV1 of \>80% of predicted and FVC of \>80% of predicted value) at screening.

Exclusion criteria

* Has known allergies or hypersensitivity or any other contraindication to mebufotenin, bufotenin, melatonin or triptans. * Has received any investigational medication, including investigational vaccines, in the 90 days prior to baseline or is in the follow-up period of another clinical trial at the time of screening for this trial. * Has a current or past clinically significant condition, which renders the subject unsuitable for the trial according to the investigator's judgement.

MeasureTime frameDescription
Serum PK parameters of mebufotenin - maximum observed concentration (Cmax)Day 1For PK analyses, blood samples will be collected before and up to 6 hours after the administration of GH001 to determine mebufotenin serum concentrations.
Serum PK parameters of mebufotenin - time of maximum observed concentration (Tmax)Day 1For PK analyses, blood samples will be collected before and up to 6 hours after the administration of GH001 to determine mebufotenin serum concentrations.
Serum PK parameters of mebufotenin - terminal elimination half-life (t1/2)Day 1For PK analyses, blood samples will be collected before and up to 6 hours after the administration of GH001 to determine mebufotenin serum concentrations.
Serum PK parameters of mebufotenin - area under the serum concentration-time curve from time zero to the last quantifiable concentration (AUClast)Day 1For PK analyses, blood samples will be collected before and up to 6 hours after the administration of GH001 to determine mebufotenin serum concentrations.
Serum PK parameters of mebufotenin - area under the serum concentration-time curve extrapolated to infinity (AUCinf)Day 1For PK analyses, blood samples will be collected before and up to 6 hours after the administration of GH001 to determine mebufotenin serum concentrations.
Serum PK parameters of mebufotenin - Partial area under the curve between t1 and t2 (AUCt1-t2)Day 1For PK analyses, blood samples will be collected before and up to 6 hours after the administration of GH001 to determine mebufotenin serum concentrations.
Serum PK parameters of mebufotenin - terminal elimination rate constant (λz)Day 1For PK analyses, blood samples will be collected before and up to 6 hours after the administration of GH001 to determine mebufotenin serum concentrations.
Serum PK parameters of mebufotenin - apparent total body clearance (CL/F)Day 1For PK analyses, blood samples will be collected before and up to 6 hours after the administration of GH001 to determine mebufotenin serum concentrations.
Serum PK parameters of mebufotenin - Apparent volume of distribution (up to bioavailability) following extravascular administration (Vz/F)Day 1For PK analyses, blood samples will be collected before and up to 6 hours after the administration of GH001 to determine mebufotenin serum concentrations.
Serum PK parameters of mebufotenin - Cmax/AUCinfDay 1For PK analyses, blood samples will be collected before and up to 6 hours after the administration of GH001 to determine mebufotenin serum concentrations.
