Randomized, Double-Blind, Placebo-Controlled Study Demonstrates 90% Day-5 Viral Clearance and Favorable Safety at Highest Dose compared to 20% placebo control
BOSTON, MA — Bioxytran, Inc. (OTCQB: BIXT), a clinical-stage biotechnology company developing carbohydrate-based therapeutics, today announced results from a randomized, double-blind, placebo-controlled Phase 1b/2a clinical study evaluating oral ProLectin-M in hospitalized patients with mild to moderate COVID-19 caused by SARS-CoV-2.
The study showed that the highest evaluated dose of ProLectin-M (16,800 mg/day) was associated with statistically significant earlier viral clearance and faster clinical improvement by Day 5 compared with placebo, while demonstrating a favorable safety and tolerability profile. By Day 7, viral clearance was observed across all study arms, consistent with the expected natural resolution of infection in this population, indicating the treatment effect may be related to accelerating viral clearance. No serious adverse events were reported, and no treatment-related discontinuations occurred.
“We believe an oral, well-tolerated antiviral with a differentiated mechanism could address important gaps in current treatment approaches, particularly in early-stage respiratory infections.” said Dr. Leslie Ajayi, Bioxytran’s Chief Medical Officer. “Our clinical data suggests ProLectin-M demonstrated earlier reductions in viral shedding compared with placebo with a favorable safety profile, and these findings support further evaluation of ProLectin-M in larger, well-controlled studies to assess its potential role as a first-line therapy.”
“These findings provide confirmation of an early clinical trials antiviral effect and support further evaluation of ProLectin-M’s novel galectin-targeting mechanism,” said David Platt, PhD, CEO of Bioxytran. “The clinical trials results are opening a new horizon for a new generation of safe anti-viral drugs. We believe the consistency of the observed activity supports continued clinical development of this oral therapeutic approach.”
Study Design
The Phase 1b/2a study enrolled 39 participants in India with RT-PCR-confirmed SARS-CoV-2 infection and mild to moderate disease. Participants were randomized to receive one of three dose levels of ProLectin-M plus standard of care (SOC), or placebo plus SOC, administered over five days.
Dose Arms:
5,600 mg/day ProLectin-M + SOC, 11,200 mg/day ProLectin-M + SOC, 16,800 mg/day ProLectin-M + SOC, Placebo + SOC.
The primary endpoint evaluated absence of detectable viral RNA at Day 7. Secondary endpoints included earlier viral clearance, changes in viral load, clinical status improvement, safety, and pharmacokinetics.
Key Findings
Earlier Viral Clearance (Day 5)
90% of participants receiving 16,800 mg/day achieved non-detectable viral shedding by Day 5. It was compared with 20.0% (placebo), 20.0% (5,600 mg), and 40.0% (11,200 mg). The difference between the 16,800 mg/day cohort and placebo was statistically significant (p=0.001).
Clinical Improvement
90% of participants in the highest-dose cohort achieved at least a 2-point improvement on the WHO Ordinal Scale by Day 5 compared with 20.0%, 40.0%, and 20.0% in the lower-dose and placebo groups. All participants improved clinically by Day 7.
Viral Load Trends
Cycle threshold (Ct) values increased over time across all groups, consistent with declining viral load. Numerically earlier Ct increases were observed in the highest-dose cohort beginning as early as Day 3, supporting the observed Day-5 antiviral signal.
Primary Endpoint Outcome
Because mild-to-moderate COVID-19 in this population typically resolves within 7 days, the primary endpoint at Day 7 did not differentiate treatment arms. However, earlier viral clearance observed at Day 5 suggests a potential acceleration of viral resolution.
Safety and Tolerability
ProLectin-M was well tolerated at all evaluated dose levels with no serious adverse events, no treatment-related discontinuations, no clinically meaningful changes in laboratory values, ECGs, or vital signs. High compliance with the 5-day dosing regimen.
Development Context
ProLectin-M is designed to target galectins, carbohydrate-binding proteins that certain viruses utilize to attach to and enter host cells. By acting on host-virus interactions rather than intracellular viral replication, this approach represents a differentiated antiviral strategy that may have applicability across multiple viral infections. In future studies, ProLectin-M may also be evaluated for its potential as a preventive therapy. The Company believes these results support continued evaluation of ProLectin-M as a potential oral therapeutic and provide a foundation for future clinical studies.
About ProLectin-M
ProLectin-M is an investigational oral antiviral being developed under an active U.S. Investigational New Drug (IND) framework as well as international regulatory oversight. The therapy leverages carbohydrate chemistry to block viral entry mechanisms mediated by galectin interactions.
