A Study of Different Doses of XTMAB-16 in Healthy Adults
Xentria is developing XTMAB-16, a type of monoclonal antibody which aims to treat people with sarcoidosis. XTMAB-16 remains under development and the safety and efficacy of it has not been determined. Before studying XTMAB-16 in patients with sarcoidosis, Xentria needed to learn how XTMAB-16 is processed by the body. We observed healthy volunteers during and after taking the study drug to check for side effects.
This is a Phase 1 Randomized, Double-blind, Placebo-controlled, First-in-Human Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of a Single Intravenous Infusion of XTMAB-16 in Healthy Adult Participants. Cohorts were investigated in a sequential dose escalation manner.
Trial Details
Sarcoidosis is a chronic, multisystem inflammatory disorder characterized by the presence of granulomas, infiltration of mononuclear cells and destruction of organ microstructure. This rare disease can affect the skin, eyes, heart, and central nervous system, with >90% of cases involving the lungs. While medications for systemic organ involvement often control this disease, some patients fail to respond to initial treatments and require additional targeted therapy, resulting in significant costs and treatment burdens. This disease presents a significant unmet medical need and a highly important area of research and development for Xentria.
Eligibility Criteria
- Be a healthy adult from 18 years of age to 45 years of age
- Weigh between 99 - 220 pounds
- Must not have underlying medical conditions
- Live in the USA
Trial Cohorts
- Two treatment cohorts for two different doses (mg/kg) administered once through intravenous (IV) infusion
- Intervention - Biological XTMAB-16; placebo
IV Infusion Single Dose
- Each Cohort will enroll 12 patients (9 on XTMAB-16 and 3 on placebo)
Primary Outcome Measure
- Safety and Tolerability: The level of risk to a participant and the degree to which an adverse event may affect day to day activities.
Secondary Outcome Measures
Safety & Tolerability
The level of risk to patient and the degree to which an adverse event may affect day to day activities.
Immunogenicity
A participant’s immune response after exposure to a treatment over a set time.
Pharmacokinetics
Profile that captures what the human body does to the treatment.
Biomarkers
Selective biological markers that help measure disease progress or a participant’s response to a treatment.
