Post-Transplant Lymphoproliferative Disorder Market

• Post-transplant lymphoproliferative disorder (PTLD) is a serious condition that can develop after organ or stem cell transplantation.
• The incidence of PTLD following organ transplantation range from 2–20%, and is primarily influenced by type of organ transplanted and immunosuppressant used. PTLD is more frequently observed in solid organ transplant recipients than in those undergoing allogeneic stem cell transplantation.
• As per secondary searches, most PTLD cases are B-cell neoplasms, and up to 35% occur within the first year after transplantation (early PTLD), with more than 50% of cases associated with Epstein–Barr virus (EBV).
• There is no FDA approved therapies for the treatment of PTLD. However, common treatments include using the drug RITUXAN (rituximab) to kill the EBV-infected B lymphocytes. 
• The cornerstone of the treatment strategy includes reducing immunosuppression, surgical removal of localized lesions, radiation therapy, immunochemotherapy, chemotherapy, stem-cell transplantation, and immunotherapy.
• EBVALLO (tabelecleucel/Tab-cel), which is an off-the-shelf allogeneic T-cell therapy, is the first and the only approved drug in the European Union for the treatment of relapsed or refractory Epstein-Barr virus positive post-transplant lymphoproliferative disease EBV+ PTLD.
• In May 2025, the FDA lifted the clinical holds on Atara’s ALLELE study and tab-cel multi-cohort studies after confirming that all issues had been satisfactorily addressed. Atara, in collaboration with Pierre Fabre, is now working to resume enrollment. 
• The PTLD pipeline is severely underdeveloped, reflecting a major unmet need and lack of innovation.

Post-transplant Lymphoproliferative Disorder (PTLD) Disease Understanding and Treatment Algorithm

Post-transplant Lymphoproliferative Disorder (PTLD) Overview

The Post-transplant Lymphoproliferative Disorder is s a rare yet significant complication that can develop after organ or stem cell transplantation, primarily affecting individuals who are administered immunosuppressive medications to prevent graft rejection. These drugs, while essential for protecting the transplanted organ, suppress the immune system and increase the risk of abnormal growth of lymphoid cells, leading to PTLD. Further, the risk of developing PTLD is highest in the first few months after transplantation, especially when immunosuppression is most intense, but it can occur at any time post-transplant.

Symptoms of PTLD are often non-specific and may include fever, swollen lymph nodes, unexplained weight loss, night sweats, and fatigue. The disorder can affect lymph nodes as well as organs, including the transplanted organ itself.

PTLD comprises a wide range of disorders, from benign lymphocyte proliferation to highly aggressive cancers called lymphomas. The majority of cases are associated with Epstein-Barr virus (EBV) infections, which can reactivate when the immune system is weakened by immunosuppressive therapy. PTLD typically arises in B-cells, however it can also affect other types of lymphocytes. 

Post-transplant Lymphoproliferative Disorder (PTLD) Diagnosis

The diagnosis of Post-transplant Lymphoproliferative Disorder involves a comprehensive approach that includes clinical evaluation, imaging tests, and laboratory investigations. Patients often present with symptoms such as fever, swollen or enlarged lymph nodes, night sweats, and unexplained weight loss. These non-specific symptoms often requires additional diagnostic investigations to confirm the diagnosis of PTLD and to distinguish it from other post-transplant complications or infections. 

Further details related to diagnosis will be provided in the report…

Post-transplant Lymphoproliferative Disorder (PTLD) Treatment

The treatment of Post-transplant Lymphoproliferative Disorder focuses on finding the right balance between controlling the abnormal proliferation of lymphoid cells and maintaining enough immune function to protect against infections. Depending on the severity and specific characteristics of the disorder, several treatment options are available. These may include reducing or adjusting the immunosuppressive medications, which can help the immune system recover and fight the abnormal cells. Targeted therapies, such as rituximab (an anti-CD20 antibody), are often used to specifically attack the abnormal lymphoid cells. In more aggressive or advanced cases, chemotherapy may be necessary, and in rare situations, radiation therapy might be considered.

Treatment plans for PTLD are highly individualized. Factors such as the type and stage of PTLD, the patient’s overall health, and the status of their transplanted organ all play a role in determining the most appropriate approach. Regular monitoring and close cooperation among transplant specialists, oncologists, and other healthcare professionals are essential to ensure optimal management of PTLD and to improve outcomes for affected patients.

Post-transplant Lymphoproliferative Disorder (PTLD) Epidemiology

The PTLD epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by the total incidence cases of transplantation, total incidence cases of PTLD, total incident cases of PTLD by EBV Status (EBV-positive, and  EBV-negative), gender-specific cases of PTLD, age-specific cases of PTLD, stage-specific cases of PTLD, and total treated cases of PTLD in the 7MM market covering the United States, EU4 (Germany, France, Italy, and Spain) and the United Kingdom, and Japan from 2020 to 2034.

• Among the 7MM, the United States has captured the highest patient share of PTLD in 2024.
• PTLD is most common in children as compared to adults.
• Approximately 45% of the PTLD cases are associated with the infection caused by EBV in 2024. This is called ‘EBV-positive PTLD’.
• As per the analysis, males are affected more with Post-transplant Lymphoproliferative Disorder as compared to females.

EBVALLO (tabelecleucel): Atara Biotherapeutics and Pierre Fabre

EBVALLO (tabelecleucel) is the first and only on-demand allogeneic T-cell immunotherapy approved for the treatment of relapsed or refractory Epstein-Barr virus positive post-transplant lymphoproliferative disease EBV+ PTLD. In December 2022, the drug received the conditional marketing authorization from the European Medicines Agency (EMA) for the treatment of relapsed or refractory EBV-positive post-transplant lymphoproliferative disease (EBV+ PTLD) in patients aged two years and older after at least one prior therapy.

Atara has progressively transitioned full global rights and manufacturing responsibilities for EBVALLO (tab-cel) to Pierre Fabre through a series of agreements and amendments, receiving milestone and royalty-related payments. By March 2025, Pierre Fabre assumed end-to-end control—including manufacturing, distribution, and cell selection—positioning it as the sole global commercializer of EBVALLO across all territories.

Atara will receive double-digit tiered royalties on EBVALLO sales in each country for at least 12 years after launch, or longer if patents or regulatory exclusivity are still in effect.

• In January 2025, the FDA issued a Complete Response Letter for EBVALLO, citing manufacturing facility inspection issues unrelated to clinical efficacy or safety, and placed a clinical hold on ongoing trials. 

• In May 2025, Atara Biotherapeutics announced that the FDA had lifted the clinical hold on Investigational New Drug (IND) applications for EBVALLO after the company addressed the agency’s concerns, allowing clinical trials to resume. EBVALLO remains a promising treatment option, pending FDA approval.

Drug Class Insight

Allogeneic T-cell immunotherapy 

Allogeneic T-cell immunotherapy involves the use of T cells derived from a healthy donor (rather than the patient) that are engineered or expanded to target cancer cells, offering an “off-the-shelf” approach to immunotherapy. In the Post-transplant Lymphoproliferative Disorder, this approach is exemplified by therapies like tabelecleucel, where allogeneic, EBV-specific cytotoxic T cells from partially HLA-matched donors are infused to recognize and eliminate EBV-infected cells driving the disease, providing a targeted treatment option for patients with relapsed or refractory PTLD after transplantation.

Post-transplant Lymphoproliferative Disorder (PTLD) Market Outlook

There are no therapies approved by the US FDA to treat PTLD, there are other treatment options that are commonly used. Other treatment options include using the drug RITUXAN (rituximab) to kill the EBV-infected B lymphocytes. The mainstay of the management strategy includes the reduction of immunosuppression, surgical excision of the localized lesion, radiation therapy, rituximab monotherapy, immunochemotherapy, chemotherapy, stem-cell transplantation, and immunotherapy. Some PTLD Cases develop resistance to conventional therapies, highlighting the need for alternative treatment strategies like targeted therapies or adoptive cell therapy.

Developing new treatments for PTLD is difficult because of the disease’s complexity. Currently, only one promising therapy is in development by Atara Biotherapeutics and Pierre Fabre. This treatment option is already approved in the EU. Ongoing research is essential to discover new biomarkers and therapeutic targets for more effective PTLD management.

Overall, it is anticipated that the market for PTLD will undergo significant changes during the forecast period 2025–2034 driven by a rising incidence of disease and the introduction of new therapies, which will likely accelerate market growth during this period.
