With 12 biosimilars already approved by the FDA and more than 70 currently in development, the oncology community is preparing for the practical and theoretical considerations involved with incorporating these treatments into practice.1
 
During a preconference presentation at the Association of Community Cancer Centers 35th National Oncology Conference in Phoenix, a panel of experts discussed the challenges they foresee with the wave of new biosimilar launches expected in 2019. The panel included Marc Earl, PharmD, BCOP; Kashyap B. Patel, MD; and Nimer Alkhatib, PharmD, MS, PhD (candidate).

Moderator Ali McBride, PharmD, MS, BCOP, Clinical Coordinator, hematology/oncology, The University of Arizona Cancer Center, questioned what the panel’s biggest hindrances were for including biosimilars in to their healthcare systems, or if any issues have been raised in addressing biosimilars related to cost models.

Patel, Medical Oncologist, Carolina Blood and Cancer Care Associates, and Earl, Assistant Director of Pharmacy-Oncology, Cleveland Clinic, agreed that one of the biggest hindrances was the lack of availability of therapeutic biosimilars in the oncology setting. While supportive care was not an issue, availability was. “I'm interested to see, now that we have multiple therapeutic biosimilars in the market, what that does to our health system,” Earl said.

McBride added that 2019 may be a very active one. “We expect almost an overload of market-based biosimilar shares,” he said. “We are going to have a lot of release dates.”

When asked what problems might arise from an institutional operationalization perspective in trying to incorporate these biosimilars into practice, Earl explained there are 3 major issues to be taken in to consideration.

“I have all my protocols built with a reference product. How do we swap that out in the IT system?” he said. “I also foresee some questions for extrapolating to all indications. What will make a provider feel comfortable with a biosimilar if the institution has decided it will use biosimilars. And, I think the third interesting question is: What role does the patient play, and should we be giving them the choice?…You're not going to notice the difference, but it is a different product. Maybe it's administered differently.”

In terms of financial assistance, Patel recognized the possibility of manufacturers’ unwillingness to participate in programs may become a barrier, as well as gaps in patient education and in getting staff on board.

“As a practitioner…patients and insurance companies have trusted me (to act as a trustee) with part of their collective fund and I have to see if I can find ways that are less expensive without compromising the outcome.”

Similarly, practitioners will have to address the overall pharmacoeconomic picture, too. Alkhatib, Pharmaceutical Economics, Health and Policy Outcome, Center for Health Outcomes and PharmacoEconomic Research (HOPE), College of Pharmacy, University of Arizona, explained that the way healthcare economists calculate value is based on four main considerations: 
  • cost effectiveness
  • cost utility
  • cost-benefit analysis
  • cost minimization

Alkhatib added that, while these factors are correct, the way they are calculated now is based on a single-payer system used in Europe. The United States uses a multi-payer system model, in which different payers have different budgets, there is a more diverse population, and there are individuals who pay out of pocket. Therefore, Alkhatib suggested for practitioners to customize pharmacoeconomic evaluations by payer for greater accuracy. 

In addition, practitioners can incorporate the financial concerns of patients into the calculation economic utility–something the European model doesn't do. Alkhatib suggested practitioners measure the patient perspective on financial value, and in turn, patient satisfaction with cost savings will increase utility value, which includes quality of life factors. 

"If we evaluate the cost utility to include the financial value of biosimilars, from the US perspective, we would have more real-world analysis and outcomes," Alkhatib summarized in a post-conference interview with Targeted Oncology.

In closing, Alkhatib shared his hope that the introduction of biosimilars in the market will change the dynamic, in that big pharmaceutical companies will have no choice but to lower their prices to compete with biosimilars.

There are more than 70 biosimilars in development, Alkhatib said, and more biosimilars mean that patients will see the benefit of reduced prices. "I am so excited about the future," he said.
