Phase 3 Trial of VMX-C001 vs Usual Pharmacological Care in Patients Taking a FXa Direct Oral Anticoagulant Who Require Urgent Surgery With or Without Heparin.
(EQUILIBRIX-S)
What this study is about
The goal of this clinical trial is to learn if VMX-C001 works to to allow blood clotting control in participants who take FXa Direct taken by mouth Anticoagulants (DOACs) during surgery or other invasive procedures that carry a high risk of bleeding.
View original scientific description
The goal of this clinical trial is to learn if VMX-C001 works to to allow blood clotting control in participants who take FXa Direct Oral Anticoagulants (DOACs) during surgery or other invasive procedures that carry a high risk of bleeding. The main question it aims to answer is: ● What is the proportion of participants in whom the stopping of bleeding was classed as good or excellent during the procedure, as judged by a group of experts who did not know which treatment was given? Researchers will compare a fixed dose of VMX-C001 to the usual treatment that would be given for the required procedure. Participants will: * Be given either a fixed dose of VMX-C001 or usual treatment before they undergo the required procedure in theatre * Have regular clinical assessments, including laboratory tests, during their hospital stay following the procedure * Return to the clinic for a check-up and tests approximately 28 days after the procedure was conducted.
Interventions
DRUG
VMX-C001
A fixed dose of VMX-C001 will be administered prior to commencement of procedure.
DRUG
Usual Pharmacological Care
Usual pharmacological care should be treatment planned to restore coagulation or support haemostasis for the required procedure.
Primary outcome measures
Effect of VMX-C001 versus usual pharmacological care on haemostasis
Time frame: From start to end of required procedure (Day 1).
Proportion of participants with good or excellent haemostatic efficacy during the required procedure.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Male or female patient aged ≥18 years.
- The patient or legally authorised representative (LAR) has given written informed consent.
- The patient requires urgent surgery/procedure for which the risk of bleeding is considered high and for which haemostasis is considered necessary.
- The patient has a significant FXa DOAC level at the time of procedure.
- The patient would require treatment (usual pharmacological care) to restore coagulation for the required procedure.
- The patient must be willing to use appropriate contraception.
Exclusion criteria
- The patient is known for any reason, other than administration of a FXa DOAC, to have an increased risk of bleeding compared to a patient in a similar clinical situation.
- The patient has received any non FXa DOAC anticoagulants within 7 days of Screening or has received heparin (UFH or LMWH) within 3 days of Screening.
- The patient has received any of the prespecified medications not allowed in the 7 days prior to Randomisation.
- The patient was treated with an investigational drug \<30 days or 5 half-lives, whichever is longer, prior to Screening.
- Expected survival, in the Investigator's judgement, is \<3 months due to comorbidity.
- Patients in whom the Investigator considers it is not possible to estimate the expected blood loss.
- Known "Do Not Resuscitate" order or similar advanced directive.
- Cardiogenic shock at the time of screening unless related to the need for the required procedure.
- The patient has sepsis (including severe sepsis or septic shock) at the time of screening.
- The patient is pregnant or a lactating female.
- Known hypersensitivity to any component of VMX-C001 or hamster proteins.
- Patients who, in the opinion of the Investigator, should not participate in the study for any other reason, or inability to comply with the protocol.
- Prior exposure to VMX-C001.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
