New hand transplant protocol aims to cut lifelong drug risks
NCT ID NCT01459107
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This Phase 2 trial at Johns Hopkins University will transplant donated hands onto 30 people who have lost one or both hands or arms. The key innovation is a bone marrow cell therapy designed to allow the body to accept the new hand with just one low-dose anti-rejection drug, instead of the usual three-drug cocktail. The goal is to restore function and appearance while reducing the long-term risks of infection, cancer, and other side effects from standard immunosuppression.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- deceased donor hand transplantation combined with bone marrow cell therapy and single-drug immunosuppression
- What this could lead to
- If successful, this could make hand transplants safer and more widely available by reducing the need for strong, lifelong anti-rejection drugs.
- What could go wrong
- This is an early Phase 2 trial with only 30 participants. The new immunosuppression approach may still cause rejection, infection, or other side effects, and results may not apply to everyone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Recipient Inclusion Criteria: * Recent (≥6 months) or remote (i.e., several decades) unilateral or bilateral upper limb loss (below the shoulder) desiring limb transplantation. * Below-shoulder amputation. * Functionless or minimally functional hand desiring removal of functionless / minimally functional hand followed by transplantation. * Male or female and of any race, color or ethnicity. * Aged 18-69 years. * Completes the protocol informed consent form. * No co-existing medical condition which, in the opinion of the study team, could affect the immunomodulatory protocol, surgical procedure, or functional results (see Donor and Recipient Exclusion Criteria below. If the condition is amenable to treatment, the study team must agree that said condition should not significantly enhance the surgical risks of upper extremity transplantation.) * No co-existing psycho-social problems (i.e., alcoholism, drug abuse). * Negative for malignancy for past 5 years. * Negative for HIV at transplant. * Negative crossmatch with donor. * If female of child-bearing potential, negative serum pregnancy test. * If female of child-bearing potential, consent to use reliable contraception for at least one year following transplantation. * Consents to bone marrow infusion as part of the treatment regime. * USA citizen or equivalent, or foreigner with documentation of ability to pay for transplant and required follow-up care. * Patient agrees to comply with the protocol and states a dedication to the immunomodulatory treatment regime. Donor Inclusion Criteria: Donors will be selected by the upper extremity transplant team in conjunction with the organ procurement organization (OPO) according to the following criteria: * Brain dead meeting the criteria for Determination of Death. * Family consent for limb donation. * Stable donor (i.e., does not require excessive vasopressors to maintain blood pressure). * Aged 16 - 65 years. * Limb matched for size with recipient. * Same blood type as recipient. * Negative lymphocytotoxic crossmatch. * Accurately matched for gender, skin tone, and race (relative requirements depending on recipient consent). Exclusion Criteria: • Positive for any of the following conditions: * Untreated sepsis. * HIV (active or seropositive). * Active tuberculosis. * Hepatitis B or C. * Viral encephalitis. * Toxoplasmosis. * Malignancy (within past 5 years). * Current/recent (within 3 months of donation/screening consent) IV drug abuse. * Paralysis of ischemic or traumatic origin. * Inherited peripheral neuropathy. * Infectious, post infectious, or inflammatory (axonal or demyelinating) neuropathy. * Toxic neuropathy (i.e. heavy metal poisoning, drug toxicity, industrial agent exposure). * Mixed connective tissue disease. * Severe deforming rheumatoid or osteoarthritis in the limb. Donor Only: • Tattoos: * Non-professional tattoo within last 6 months, or * Personally identifiable tattoo (i.e., donor name) on potential transplant. Recipient Only: * Type I (insulin-dependent) diabetes mellitus * Conditions that, in the opinion of the study team, may impact the immunomodulatory protocol potentially exposing the recipient to an unacceptable risk under immunosuppressive treatment. * Sensitized recipients with high levels (50%) of panel-reactive human leukocyte antigen (HLA) antibodies. * Conditions that may impact the success of the surgical procedure or increase the risk of postoperative complications including inherited coagulopathies like Hemophilia, Von-Willebrand's disease, Protein C and S deficiency, Thrombocythemias, Thalassemias, Sickle Cell disease, etc. * Mixed connective tissue diseases and collagen diseases can result in poor wound healing after surgery. * Conditions that may impact functional outcomes including Lipopolysaccharidosis and amyloidosis (may impact nerve regeneration) or rare disorders of bone healing like osteopetrosis. * Patients considered unsuitable per the consulted Psychiatrists appraisal.
