Trial Outcomes & Findings for A Study to Understand the Effect of a Study Medicine Called ARV-471 on Dabigatran Etexilate in Healthy Adults (NCT NCT05673889)

The study consisted of 2 Periods in a single fixed sequence. Twenty-four participants were screened and passed. All 24 participants were assigned to the study treatment and all completed the study.

Cmax was defined as maximum observed plasma concentration. Cmax for total dabigatran was observed directly from data.

AUCinf was defined as area under the concentration-time curve from time 0 extrapolated to infinity. AUCinf was calculated by AUClast + (Clast/kel), where Clast was the predicted plasma concentration at the last quantifiable time point from the log-linear regression analysis and kel was the terminal phase rate constant calculated by a linear regression of the log-linear concentration time curve; AUClast was defined as area under the plasma concentration-time profile from time 0 to the time of the last quantifiable concentration.

An AE is any untoward medical occurrence in a participant who received study intervention without regard to possibility of causal relationship with the study intervention. SAE is defined as one of the following: is fatal or life threatening; results in persistent or significant disability/incapacity; constitutes a congenital anomaly/birth defect; is medically significant; requires inpatient hospitalization or prolongation of existing hospitalization. Treatment-emergent AE is defined as an AE with onset date occurring during the on-treatment period. AEs include all SAEs and non-SAEs.

Following parameters were analyzed for laboratory examination: hematology (hemoglobin, hematocrit, red blood cell count, platelet count, white blood cell count, total neutrophils, eosinophils, monocytes, basophils, lymphocytes); liver function (aspartate aminotransferase, alanine aminotransferase, total bilirubin, alkaline phosphatase, albumin, total protein); renal function (blood urea nitrogen, creatinine, uric acid, cystatinC); electrolytes (sodium, potassium, chloride, calcium, bicarbonate); clinical chemistry (glucose); urinalysis (dipstick \[decimal logarithm of reciprocal of hydrogen ion activity {pH} of urine, glucose, protein, blood, ketones, nitrites, leukocyte esterase, urobilinogen, bilirubin\], microscopy. Abnormality was determined at the investigator's discretion.

Vital signs (blood pressure and pulse rate) were obtained with participant following at least a 5-minute rest in a supine position. Clinical significance of vital signs was determined at the investigator's discretion.

ECG abnormalities criteria include a) a postdose QTc corrected using Fridericia's formula (QTcF) increased by \>60 millisecond (ms) from the baseline and the absolute QTcF value \>450 ms; or b) an absolute QTcF value \>500 ms for any scheduled ECG.
