Clinical Research Division, Fred Hutch
Dr. Ajay Gopal develops new targeted treatments for patients with lymphoma. One of his focus areas is radioimmunotherapy, a precision-targeted form of radiation designed to kill cancer cells while minimizing damage to healthy cells. In radioimmunotherapy, cancer-targeting antibodies carry radioactive particles straight to tumors, bypassing healthy tissues. Dr. Gopal conducts clinical trials of new bone marrow transplant protocols that incorporate radioimmunotherapy to prepare patients for transplantation. Dr. Gopal also conducts clinical research on low-toxicity drugs for patients with indolent lymphomas that activate the cancer cells’ self-destruct mechanism. Finally, Dr. Gopal studies new strategies for safely curing lymphoma in older adults. He is director of clinical research in hematological malignancies and hematology at Seattle Cancer Care Alliance, Fred Hutch’s clinical-care partner.

Developing novel targeted therapies for lymphomas with particular emphasis on radioimmunotherapy-based transplant conditioning regimens, low toxicity proapoptotic agents for indolent lymphomas, and safe curative regimens for older adults with lymphoma.
1. LLS T-NHL
Leukemia & Lymphoma Society; Leukemia & Lymphoma Society Scholar in Clinical Research
The major goal of this grant is to translate laboratory data into the first clinical trial using high doses of radioactively tagged anti-CD45 antibody to deliver potentially curative radiation to multiple T-NHL prior to stem cell transplantation.
2. P01 CA 044991
NIH/NCI; Therapy of Lymphoma/Leukemia with Monoclonal Antibodies
This program project grant is developing improved strategies for treating patients with hematologic malignancies using radiolabeled monoclonal antibodies. It contains human clinical trials of high dose radioimmunotherapy with stem cell transplantation for leukemia (Project 1), lymphoma (project 2) and for pretargeted radioimmunotherapy of hematologic malignancies (Project 3).
3. Project 2
Radiolabeled Therapy of Lymphoma; A phase I clinical trial of 90Y-labeled anti-CD45 BC8 antibody will be conducted in patients with lymphoma undergoing autologous stem cell transplantation. The optimal antibody protein dose of BC8 will be determined (Aim 1), direct comparisons of the biodistributions of CD45 and CD20 antibodies will be conducted (Aim 2), and the biodistributions of111In-BC8 with gamma camera imaging and 86Y-BC8 with PET imaging will be compared (Aim 3). Patients will be treated following the biodistribution studies with escalating doses of 90Y-BC8 to estimate the MTD in the setting of ASCT (Aim 4).
4. Project 3
Pretargeted Radioimmunotherapy for Leukemia & Lymphoma
Phase I clinical trials of pretargeted radioimmunotherapy using anti-CD45 antibody conjugated to streptavidin followed by radiolabeled DOTA-biotin will be conducted in the setting of non-hematopoietic cell transplantation (HCT) for leukemia (Aim 1) and lymphoma (Aim 2). In addition, we the biodistributions and dosimetries of radiobiotin pretargeted using anti-CD45 BC8-SA will be compared with those observed with directly radiolabeled anti-CD45 BC8 Ab in patients with leukemia and lymphoma (Aim 3).
