How One Cancer Survivor Triggered Interest in Repurposed Anti-Parasitic Drugs

Image
Joe Tippens never planned to discover a potential remedy that he credits with saving his life and thrust him into the spotlight among notable cancer survivors. The 67-year-old businessman told The Epoch Times he just wanted to beat a type of cancer with an extremely low survival rate. In August 2016, Tippens was diagnosed with small cell lung cancer with a fist-sized tumor. After undergoing chemotherapy and radiation five times a week in Houston, the large tumor in his left lung was eliminated. However, Tippens said the treatments came closer to killing him than curing him. When he returned home to Oklahoma after the New Year, he received devastating news. His oncologist told him he had zero chance of surviving for more than a few months. “In January of 2017, my PET scan lit up like a Christmas tree and I had wide metastasis everywhere, including in my neck, bones, pancreas, and liver,” Tippens said. Finding a Lifeline Facing a prognosis of three months to live, Tippens heard an intrig...

Potential Role of Fenbendazole and Ivermectin in the Treatment of Stage 4 Pancreatic Cancer: A Compilation of Case Reports and Mechanistic Insights (2025)

Image
Summary Background: Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal malignancies, with limited effective therapies and poor survival, especially in stage 4 disease. Repurposing antiparasitic agents such as fenbendazole and ivermectin has garnered interest due to their demonstrated anti-cancer properties in preclinical studies. Methods: We reviewed and synthesized 20 detailed case reports from 2022 to 2025 documenting the clinical use of fenbendazole and ivermectin, alone or in combination with standard therapies, in patients with advanced pancreatic cancer. Tumor markers, imaging outcomes, and clinical responses were analyzed alongside mechanistic literature. Results: Across cases, patients exhibited marked reductions in CA19-9 tumor markers (often >70%), significant tumor shrinkage on imaging, and improved clinical status. Responses were observed even in chemotherapy-resistant and metastatic disease. Mechanistic studies support multiple anti-cancer effects of...

CAR-T vs CAR-NK Cell: The Cancer Cell Therapy Showdown (2025)

Image
One of the most promising approaches in cellular therapies is immunotherapies using engineered T cells or natural killer (NK) cells expressing chimeric antigen receptors (CARs). Will CAR-NK cell therapies overshadow traditional CAR-T options for the treatment of some cancers? Recently researchers have tried to modify natural killer (NK) cells with chimeric antigen receptors (CAR) to increase potential to bind and destroy cancer cells, known as NK cell therapy. Here we describe the differences between CAR T cell therapies and CAR NK cell therapies to consider when developing cancer treatments for patients. What is CAR-T? T cells are part of the adaptive immune system and are intended to generate a long lasting protective immune response. By engineering T cells with the Natural Killer Group 2D (NKG2D) receptor, they become NKG2D CAR T cell therapies. What is CAR-NK?  NK cells are a part of the innate immune system and are the first line of defense against foreign infections and canc...

CAR T-Cell Therapy for Glioblastoma: 3 Case Reports

Image
A collaborative project to bring the promise of cell therapy to patients with a deadly form of brain cancer has shown dramatic results among the first patients to receive the novel treatment. In a paper published today in The New England Journal of Medicine , researchers from the Mass General Cancer Center, a member of the Mass General Brigham healthcare system, shared the results for the first three patient cases from a phase 1 clinical trial evaluating a new approach to CAR-T therapy for glioblastoma (GBM). The trial, known as INCIPIENT, is designed to evaluate the safety of CARv3-TEAM-E T cells in patients with recurrent GBM. Just days after a single treatment, patients experienced dramatic reductions in their tumors, with one patient achieving near-complete tumor regression. In time, the researchers observed tumor progression in these patients, but given the strategy’s promising preliminary results, the team will pursue strategies to extend the durability of response. “This is a s...
