Trial Summary

What is the purpose of this trial?

Background: Millions of people each year sustain injuries, have tumors surgically removed, or are born with defects that require complex reconstructive surgeries to repair. In the case of hand, forearm, or arm amputation, prostheses only provide less than optimal motor function and no sensory feedback. However, hand and arm transplantation is a means to restore the appearance, anatomy, and function of a native hand. Although over 70 hand transplants have been performed to date and good functional results have been achieved, widespread clinical use has been limited due to adverse effects of life-long and high-dose immunosuppression needed to prevent graft rejection. Risks include infection, cancer, and metabolic problems, all of which can greatly affect recipients' quality of life, make the procedure riskier, and jeopardize the potential benefits of hand transplantation. Study Design: This non-randomized, Phase II clinical trial will document the use of a new immunomodulatory protocol (aka - Pittsburgh Protocol, Starzl Protocol) for establishing hand transplantation as a safe and effective reconstructive treatment for upper extremity amputations by minimizing maintenance immunosuppression therapy in unilateral and bilateral hand/forearm transplant patients. This protocol combines lymphocyte depletion with donor bone marrow cell infusion and has enabled graft survival using low doses of a single immunosuppressive drug followed by weaning of treatment. Initially designed for living-related solid organ donation, this regimen has been adapted for use with grafts donated by deceased donors. The investigators propose to perform 30 human hand transplants employing this novel protocol. Specific Aims: 1) To establish hand transplantation as a safe and effective reconstructive strategy for the treatment of upper extremity amputations; 2) To reduce the risk of rejection and enable allograft survival while minimizing the requirement for long-term high dose multi-drug immunosuppression. Significance of Research: Hand transplantation could help upper extremity amputees recover functionality, self-esteem, and the capability to reintegrate into family and social life as "whole" individuals. The protocol offers the potential for minimizing the morbidity of maintenance immunosuppression, thereby beneficially shifting the risk/benefit ratio of this life-enhancing procedure and enabling widespread clinical application of hand transplantation.

Do I need to stop my current medications for the hand transplant trial?

The trial information does not specify if you need to stop your current medications. However, since the trial involves immunosuppressive treatment, it's possible that some medications might need to be adjusted. It's best to discuss your specific medications with the study team.

What data supports the effectiveness of the treatment Deceased Donor Hand Transplantation for hand loss from trauma?

Hand transplantation has shown promising results, with 100% patient survival and graft survival at 1 and 2 years, and most patients achieving protective and discriminative sensation, allowing them to perform daily activities and return to work. Additionally, 15 recipients reported an improved quality of life, highlighting the potential benefits of this treatment. ^{1 2 3 4 5}

Is hand transplantation safe for humans?

Hand transplantation has been shown to be generally safe in humans, with no life-threatening complications or cancers reported. However, patients need to take lifelong immunosuppressive drugs, which can have serious side effects, and there is a risk of rejection if the medication is not taken as prescribed. ^{1 2 3 4 6}

How is the Pittsburgh Protocol treatment for hand transplantation unique?

The Pittsburgh Protocol for hand transplantation is unique because it aims to minimize the use of multiple immunosuppressive drugs, which are typically required for life to prevent rejection of the transplanted hand. This approach focuses on using a single-drug immunosuppression strategy, potentially reducing the risk of serious side effects associated with long-term use of multiple immunosuppressive medications. ^{1 5 6 7 8}

Findings from Research

Hand transplantation has evolved significantly over the past decade, showing promising immunological and functional outcomes, but the need for lifelong immunosuppression remains a major challenge due to potential side effects.

Recent advancements in immunosuppressive drugs and innovative cell-based therapies are demonstrating success in reducing the need for immunosuppressive medication and promoting tolerance, which could improve the overall safety and effectiveness of hand transplantation.

Minimizing immunosuppression in hand transplantation. Brandacher, G., Lee, WP., Schneeberger, S.[2022]

A new immunomodulatory protocol for hand transplantation, which includes donor bone marrow infusion and low-dose tacrolimus, has been successfully applied in clinical settings, leading to good-to-excellent functional recovery in patients.

This approach allows for a favorable risk-benefit balance by minimizing immunosuppression while still enabling transplant recipients to regain autonomy and productivity in their lives.

In a review of 24 hand transplantations performed on 18 male patients, both patient and graft survival rates were 100% at 1 and 2 years, highlighting the efficacy of the immunosuppressive therapy used, which included tacrolimus and mycophenolate mofetil.

Despite some cases of acute rejection, all compliant patients experienced reversible rejection episodes, and 90% of recipients returned to work, indicating significant improvements in quality of life and functional recovery after transplantation.

Hand transplantation is a viable option for select patients with traumatic upper extremity amputations, with 72 hands successfully transplanted in 51 patients worldwide since 1998.

A major challenge in hand transplantation is the need for lifelong immunosuppression to prevent rejection, particularly of the skin, which is the most vulnerable tissue; ongoing research aims to minimize this immunosuppression to improve the procedure's applicability.

The first double hand transplantation using a conventional immunosuppressive protocol was successful in a 33-year-old man, demonstrating both safety and efficacy over a two-year follow-up period.

Despite two episodes of acute rejection, which were effectively managed, the patient experienced no serious complications such as infections or malignancies, indicating that the immunosuppressive regimen was well-tolerated and effective for graft survival.

Recent advances in transplant immunology are enabling the possibility of composite tissue allotransplantation with less potent immunosuppressive regimens, which could improve patient outcomes.

Hand transplantation has been the most common type of composite tissue allotransplantation, with over 50 procedures performed globally, highlighting its growing acceptance and potential in enhancing quality of life for patients.

Hand transplantation shows promising functional results, with six patients in this study recovering protective and some discriminative sensation in their transplanted hands, indicating better outcomes compared to prosthetic options.

The study involved a well-defined immunosuppressive protocol and reported no surgical complications, although all patients experienced skin rejection at an average of 40 days post-surgery, highlighting the importance of adherence to immunosuppressive therapy to prevent rejection.
