A CELL THERAPY BREAKTHROUGH — The FDA’s Friday approval of the first cell therapy for solid tumors marks a major development in cancer treatment and individualized therapies. Yet, the treatment’s accessibility, high costs and demanding and unpleasant regimen could limit its reach as with other approved cell and gene therapies. Iovance Biotherapeutics’ Amtagvi, indicated to treat advanced melanoma — the deadliest form of skin cancer — is a type of therapy that employs tumor-infiltrating lymphocytes, or TILs. The novel treatment is the first non-CAR T-cell therapy to hit the market. FDA-approved CAR T-cell treatments are targeted for blood cancers, which represent about 10 percent of the cancers diagnosed in the U.S. annually. How the therapy works: TILs are made by biopsying a piece of the patient’s tumor and expanding and engineering the immune cells to boost their ability to fight the cancer, Dr. Jason Bock, CEO of the Cell Therapy Manufacturing Center, told Prescription Pulse. CTMC is affiliated with MD Anderson Cancer Center in Houston. The manufacturing process takes about a month before the patient can receive the single-dose infusion, Bock said. “These are literally the most complicated medicines we’ve ever tried to develop,” he said. Like gene therapies, Amtagvi won’t be cheap for payers, with an initial list price of $515,000. Patients will face access challenges similar to those associated with gene therapies. Iovance said more than 30 authorized treatment centers that can administer the therapy are active, with about 20 more expected to come online within the next three months. Bock said next-generation products that require infusing fewer cells and rely less on co-administered medicines to prepare patients for treatment would help bring down costs. People receiving Amtagvi must take high doses of interleukin-2, used to boost the immune system’s cancer-fighting power with a regimen that carries plenty of its own serious adverse effects and high costs. Still, the accelerated approval is a breakthrough for metastatic or unresectable melanoma patients with limited treatment options, FDA officials said. IT’S WEDNESDAY.
