Phase 1 BAFF CAR T clinical trial for patients with relapsed and refractory multiple myeloma underway at UH Seidman Cancer Center

Study is being done through an agreement between UH and Luminary Therapeutics

2024-08-14
(Press-News.org) CLEVELAND – University Hospitals (UH) Seidman Cancer Center hematologist-oncologist Leland Metheny, MD, is leading the trial. He says in the two years since the foundational pre-clinical work was completed, the team has shown that it’s feasible to manufacture BAFF CAR T-cells for human subjects. The innovation is introducing genes into T-cells via the process of electroporation in the Wesley Center for Immunotherapy at UH Seidman Cancer Center.

In January 2022, a research team from UH Seidman Cancer Center and Case Western Reserve University published a groundbreaking report in the journal Nature Communications, detailing a novel approach to chimeric antigen receptor (CAR) T-cell therapy for B-cell cancers. The new B-cell activating factor (BAFF) CAR T product, developed by UH Seidman Cancer Center and Case Western Reserve University scientist Reshmi Parameswaran, MS, PhD, and colleagues, binds specifically to each of three receptors instead of one – BAFF-R, BCMA and TACI, providing more therapeutic options and guarding against the problem of antigen escape currently found in CAR T therapies that solely target CD19. Experimental results showed that the BAFF CAR T is effective at killing multiple B-cell cancers, with robust in vitro and in vivo cytotoxicity exerted by BAFF CAR T-cells against mantle cell lymphoma, multiple myeloma and acute lymphoblastic leukemia xenograft mouse models.

Now just two short years later, these crucial findings are the basis for the Phase I BAFF CAR T clinical trial for patients with relapsed and refractory multiple myeloma.

The new multiple myeloma trial at UH Seidman will proceed with up to 20 patients with relapsed or refractory myeloma and three or more prior lines of therapy, including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 monoclonal antibody.

“Our study will evaluate for a safe dose and provide the initial signal of the activity of BAFF CAR T-cells against relapsed myeloma. We will be using a manufacturing process that could be replicated in multiple academic institutions with the appropriate cellular manufacturing facilities,” Dr. Metheny says.

Its primary goal is to determine the maximum tolerated dose and recommended dose of BAFF CAR T-cells for a Phase II trial. Secondary objectives include establishing the toxicity profile, objective response rate, complete response rate, duration of response, progression-free survival, overall survival, the incidence of adverse events and the incidence of antibodies against the BAFF CAR T-cells. Dr. Metheny and the team will collect data over 24 months.

Dr. Metheny says he’s excited about the potential for the patients he treats.

“There is a persistent need for development of new, effective therapies for treatment of myeloma,” he says. Therapy with CAR T-cells has demonstrated activity against refractory myeloma. Through this trial, we are assessing if BAFF CAR T-cells can become another strategy for our patients with refractory disease.”

The study is being done through an agreement between University Hospitals and Luminary Therapeutics, a biotech start-up based in Minneapolis. Luminary is an allogeneic CAR T drug development company with programs addressing B-cell malignancies, autoimmune disease and solid tumors.

Microscopic packets could deliver diabetes-preventing therapeutics

2024-08-14
Within each of us lies an army of cells whose topmost duty is protecting against external pathogens and internal threats such as proliferating cancer cells. Yet, immune cells can sometimes erroneously attack the body, causing autoimmune diseases like type 1 diabetes. Texas A&M researchers recently received an RO1 grant from the National Institutes of Health to develop a strategy to deliver immune-suppressing proteins generally produced by specialized stem cells. Such an approach could potentially help reduce the immune system's attack on the insulin-producing beta-cells in the pancreas and open doors to a novel treatment for type 1 diabetes. "We are excited that the ...

New brain-computer interface allows man with ALS to ‘speak’ again

New brain-computer interface allows man with ALS to ‘speak’ again
2024-08-14
A new brain-computer interface (BCI) developed at UC Davis Health translates brain signals into speech with up to 97% accuracy — the most accurate system of its kind. The researchers implanted sensors in the brain of a man with severely impaired speech due to amyotrophic lateral sclerosis (ALS). The man was able to communicate his intended speech within minutes of activating the system. A study about this work was published today in the New England Journal of Medicine. ALS, also known as Lou Gehrig's disease, affects the nerve cells that control movement ...

International study detects consciousness in unresponsive patients

2024-08-14
New research co-led by experts at Mass General Brigham found that brain scans can detect consciousness in some patients with brain injury who are unresponsive. In the study, 241 participants with severe brain injury who do not respond when given a simple instruction were assessed with functional MRI (fMRI), electroencephalography (EEG), or both tests. During these tests, participants heard instructions, such as “imagine opening and closing your hand” followed, 15-30 seconds later by “stop imagining opening and closing your hand.” The fMRI and EEG brain ...

Benjamin Manard, an analytical chemist in the Chemical Sciences Division of the Department of Energy’s Oak Ridge National Laboratory, will receive the 2024 Lester W. Strock Award from the Society of Applied Spectroscopy. The prize is named for the late Lester W. Strock, a crystal chemist and pioneer in applied spectroscopy. The annual award recognizes researchers who produce outstanding publications in analytical atomic spectrochemistry. “Manard’s publications over the last five years demonstrate a clear focus on the elemental and isotopic analysis of nuclear materials using a variety ...

Patients with unexplainable chronic itch have unique blood biomarkers that could eventually lead to new targeted treatments

2024-08-14
Millions of patients worldwide suffer from a chronic itching condition with no identifiable cause – a condition known as chronic pruritus of unknown origin (CPUO) – that has no targeted therapies approved to treat it. Many of these patients suffer for years with little relief, but a new University of Maryland School of Medicine study may provide hope for future treatments. Patients were found to have lower than normal levels of metabolite biomarkers in the blood plasma that could point to a cause of their excruciating symptoms. Findings were recently published in the journal Scientific Reports. “Our study found a distinct deficit in certain metabolite ...
