The US Food and Drug Administration (FDA) recently approved the tumor-infiltrating lymphocyte cell therapy (TIL) for use in certain adults with unresectable or metastatic melanoma. This marks the first time the FDA has allowed a cellular therapy to be marketed for a solid tumor cancer.
Lifileucel is made from a patient’s surgically removed tumor. Tissue from that tumor is then sent to a manufacturing center. Turnaround time to when the drug is ready to be sent back to the cancer center for use is approximately 34 days, according to the drug’s manufacturer, Iovance.
Insurance Adjustments
The cost of the one-time lifileucel treatment is $515,000, according to the manufacturer.
Two investigators in the clinical trials of lifileucel, Allison Betof Warner, MD, of Stanford University, Stanford, California, and Igor Puzanov, MD, of Roswell Park Comprehensive Cancer Center, Buffalo, New York, shared their expectations regarding factors that would contribute to how much a patient paid for the drug.
Given the drug’s recent approval, the logistical details are still being worked out between cancer centers and insurers regarding how much patients will pay out of pocket for lifileucel, said Dr. Betof Warner, who is assistant professor in the Department of Medicine, Division of Medical Oncology at Stanford University.
The associated costs, including the surgery that is needed to procure the TIL cells for expansion into the final drug product, will be different for each patient, she told this publication.
Patients’ costs for lifileucel will vary based on their insurance, explained Dr. Puzanov, chief of melanoma and professor of oncology at Roswell Park Comprehensive Cancer Center.
At Roswell Park, “we will work with our regionally-based payers on a case-by-case basis to seek approval for those patients we believe can most benefit from lifileucel,” he said in an interview. Preauthorization will be required, as is standard for many cancer treatments, he added.
Once payer approval is in place, Dr. Puzanov said, he did not anticipate significant delays in access for patients.
Certified centers such as the multidisciplinary team at Roswell Park are ready to treat patients now. Other centers are similarly prepared, especially those involved in the clinical trials of lifileucel, he said.
Logistics and Infrastructure
A position article and guidelines on the management of and best practices for TIL was published in the Journal for ImmunoTherapy of Cancer on February 29. The paper, of which both Dr. Betof Warner and Dr. Puzanov served as authors, noted that one of the barriers to the use of TIL cell therapy in clinical practice is the need for state-of-the art infrastructure at centers that want to offer the treatment. Scheduling, patient referrals, and surgery, as well as the production and infusion of TIL, must be organized and streamlined for successful treatment, the authors wrote.
The two supply chains involved in TIL — the transportation of the tumor tissue from the treatment center to the manufacturer and transport of the TIL infusion product back to the treatment center — must be timely and precise, they emphasized.
Docs Hope TIL Improves in Several Ways
Although the TIL technology is a breakthrough, “we hope to see even better efficacy and lower toxicity as further research looks at ways to improve on the current TIL standard,” Dr. Puzanov said.
More research and dose adjustments may impact patient costs and side effects, he noted. “I am looking to see TILs used in the front line, with or without checkpoint inhibitors.”
Research is needed to explore how to lower the chemotherapy doses and possibly the associated toxicity, he added. Finally, researchers must consider whether high-dose IL-2 therapy — given as part of the TIL cell therapy — could be replaced with other cytokines, or whether the number of doses could be lowered. Another avenue of exploration is engineering genes for cytokines into TILs, he said.
“The key is to think about TIL therapy before you need it — ideally, when the patient is still doing well on their frontline checkpoint inhibition immunotherapy,” Dr. Puzanov said in an interview. That is the time for evaluation, and specialty centers can provide an expert assessment, he said.
“We are constantly working to improve TIL therapy,” Dr. Betof Warner told this publication. More research is needed optimize the regimen to reduce side effects, which would not only make treatment easier for currently eligible patients, but might allow treatment for patients not currently eligible.
“For example, we are looking for ways to reduce the dose of preparative chemotherapy, which prepares the body for the cells to maximize their longevity and efficacy, and to reduce or eliminate the need to give IL-2 after the cell administration,” continued Dr. Betof Warner, who is also Director of Melanoma Medical Oncology, Director of Solid Tumor Cellular Therapy, and Codirector of the Pigmented Lesion and Melanoma Program at Stanford University. “We are also actively studying next-generation TIL therapies to try to increase the efficacy.”
“Lifileucel has about a 30% success rate for melanoma that has progressed after standard therapy; we are working hard to do better than that,” she noted.
In a press release, Iovance summarized the results of the trial that supported the FDA’s accelerated approval of lifileucel. In an open-label single-arm study, including multiple sites worldwide, 73 adults with unresectable or metastatic melanoma who had received at least one previous systemic therapy underwent a lymphodepleting regimen followed by treatments with fludarabine and aldesleukin. Patients then received lifileucel at a median dose of 21.1 x 109 viable cells; the recommended dose ranges from 7.5 x 109 to 72 x 109 cells.
The primary efficacy outcome was objective response rate (ORR). The ORR in the study was 31.5%, and the median time to initial lifileucel response was 1.5 months.
The clinical trials of lifileucel for which Dr. Betof Warner and Dr. Puzanov served as investigators were sponsored by Iovance.
