A Study to Assess the Safety and Effects of the Investigational Drug BW-40202 in Healthy Volunteers

July 22, 2025 updated by: Shanghai Argo Biopharmaceutical Co., Ltd.

A Phase 1, Randomized, Double-Blind, Placebo-Controlled, Single Ascending Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Subcutaneously Administered BW-40202 in Healthy Subjects

This study will test the safety of a new drug called BW-40202 in healthy adults. The drug is a clear liquid given as an injection under the skin (subcutaneous injection). The study will test five different doses of BW-40202 compared to a placebo (saltwater solution).

Participants will be divided into five groups, with each group receiving a different dose of BW-40202 or placebo. In each group, eight people will be randomly assigned to receive either the drug (6 people) or placebo (2 people).

The Safety Review Committee will review the safety data before increasing the dose for the next group.

Study nurses or trained staff will give the injections. Pharmacy staff will keep records of how much drug each participant receives, any returned or destroyed doses, and any changes from the planned dosing schedule. These records will be securely stored and available for review.

Measure Description
Time Frame
maximum plasma concentration data (Cmax, ng/mL) of BW-40202 will be collected for all cohorts at the scheduled PK sampling timepoints.
Time Frame: From first patient enrolled until Day 8 post-dose of last patient.

  1. Collect Plasma Concentration Data Blood samples are collected at predetermined time points after drug administration.

    The drug concentration in plasma is measured at each time point.

  2. Plot the plasma concentration-time curve X-axis: time after drug administration y-axis: plasma drug concentration
  3. Identify the highest observed concentration locate the highest data point in the plasma concentration-time curve the corresponding drug concentration value is Cmax
From first patient enrolled until Day 8 post-dose of last patient.
Time to Maximum plasma concentration (Tmax, hr) of BW-40202 will be calculated (hr). T max(Time to Maximum Concentration) is the time at which the maximum observed plasma drug concentration ( Cmax) occurs after drug administration.
Time Frame: From first patient enrolled until Day 8 post-dose of last patient.

  1. Collect Plasma Concentration Data Blood samples are collected at predetermined time points after drug administration.

    The drug concentration in plasma is measured at each time point.

  2. Plot a Concentration-Time Curve The plasma drug concentration (C) is plotted on the Y-axis. Time post-dose (T) is plotted on the X-axis.
  3. Identify Cmax ⁡Determine the highest drug concentration observed in plasma. The corresponding time point is Tmax
From first patient enrolled until Day 8 post-dose of last patient.
Calculate the Area Under the Plasma Concentration-Time Curve (AUC, hr*ng/mL), to estimate the AUC beyond the last observed time point (AUC0-∞), the AUC from 0 to 24 hours and AUC from 0 to 48 hours. The AUC represents the total drug exposure over time.
Time Frame: From first patient enrolled until Day 8 post-dose of last patient.

AUC (0-∞), Total drug exposure from time zero to infinity (extrapolated). The equation used to calculate Area Under the Plasma Concentration-Time Curve from Zero to Infinity AUC(0-∞) is based on the trapezoidal rule and extrapolation using the elimination rate constant (λz).

AUC(0-24), Total drug exposure form time zero to 24 hours. The equation used to calculate Area Under the Plasma Concentration-Time Curve from Zero to 24 Hours (AUC₀-₂₄) is based on the trapezoidal rule and is called the Linear Trapezoidal Rule.

AUC(0-48) , total drug exposure from time zero to 48 hours. The equation used to calculate Area Under the Plasma Concentration-Time Curve from Zero to 48 Hours AUC(0-48) is based on the trapezoidal rule and is called the Linear Trapezoidal Rule.
From first patient enrolled until Day 8 post-dose of last patient.
Calculate the time required for the plama concentration of a drug to decrease by 50% in the elimination phase. Which is called terminal elimination half-life (t1/2, hr)
Time Frame: From first patient enrolled until Day 8 post-dose of last patient

  1. Identify the Terminal Elimination Phase Plot a plasma concentration-time curve (log scale on Y-axis, linear scale on X-axis).

    Focus on the terminal elimination phase, where the concentration follows first-order kinetics (a straight line on a semi-log graph).

  2. Calculate the Elimination Rate Constant (Ke) Use the slope of the terminal phase of the log-transformed concentration-time curve
  3. Calculate the t1/2 using formula: t1/2=ln2/ke=0.693/ke.

Calculate the Urine output (Aet, mg), Aet (total amount of drug excreted in urine during each time interval)
Time Frame: From first participant being enrolled until 24 hours post-dose of last enrolled participant
Total amount of drug excreted in urine from time t1 to t2 hours (for each urine time interval) Aet1 - t2=Cut1-t2*Vut-t2, where Vut1-t2 = the volume of urine collected from t1 to t2 and Cu t1-t2 = the concentration of drug in the collected urine. Parameters of interest are Ae0-4, Ae4-12, and Ae12-24.
From first participant being enrolled until 24 hours post-dose of last enrolled participant
Calculate the Urine output (Clr, L/h), the renal clearance measures the efficiency of drug elimination by the kidneys.
Time Frame: From first participant being enrolled until 24 hours post-dose of last enrolled participant
Renal clearance calculated as CLr = CAe/Plasma AUC0-24. Ae=cumulative amount excreted in urine (mg). AUC0-24 = Area under the plasma concentration - timecurve from 0 to 24 hours (e.g. mg*h/mL)
From first participant being enrolled until 24 hours post-dose of last enrolled participant
