In 2017, the U.S. FDA approved two groundbreaking chimeric antigen receptor (CAR) T-cell therapies – Kymriah and Yescarta – to treat acute lymphoblastic leukemia and diffuse large B-cell lymphoma, respectively. These novel therapies utilize a patient’s own immune cells to attack and kill the cancer, and they have shown promise in treating and, in a few cases, “curing” otherwise incurable hematological malignancies.
Despite the breakthrough nature of the clinical data, these first-wave CAR-T 1.0 therapies are struggling to find commercial success,1 due to factors including:
Despite these commercial challenges, the clinical promise has helped trigger substantial follow-on research to harness CAR-T to treat other cancers, including multiple myeloma and solid tumors. In keeping with the tremendous excitement for these therapies, investment in a second wave of CAR-T drugs is strong, with more than 270 trials underway and exponential market growth estimated at nearly 50 percent between 2019 and 2028.4
Potential Barriers To CAR-T 2.0 Commercial Success
As this second wave of CAR-T therapies begins coming to market in the next five years, their manufacturers will need to anticipate and prepare to address many of the same commercial challenges as their predecessors, as well as several additional ones, including:
4 Market Development Strategies For CAR-T 2.0
Innovators bringing the next generation of CAR-T therapies to market should give heed to and prepare to navigate the challenges identified above. Current and future players must recognize and execute against two key strategic imperatives: 1) optimizing the 360-degree stakeholder experience, and 2) demonstrating clear value through evidence generation. Preemptively addressing these likely future obstacles and opportunities early in the market development process will position CAR-T players well for CAR-T 2.0.
1. Effective Physician Education
To holistically optimize the stakeholder experience, 2.0 innovators must provide effective physician education. Currently, because of the novelty and complexity associated with CAR-T therapies, highly specialized medical experts at selected centers of excellence administer the vast majority of treatments. Indication expansion may lead to capacity issues at these centers, especially because these new indications generally are treated in the community.
One strategy to address these concerns is to facilitate CAR-T adoption in the community. However, to successfully drive adoption, it will be critical to effectively educate community physicians on CAR-T toxicity management, as well as on the clinical benefits of CAR-T therapies over other available options. Innovators that anticipate this shift and take measures to help community providers — who already treat nearly 55 percent of all U.S. patients — to adopt their therapies will gain a competitive advantage.6 Players who fail to do so may risk being bypassed by these community providers in favor of other available agents. In other words, educating community oncologists will be a driving factor that determines the success of CAR-T 2.0.
While a wholesale move to the community may not be feasible in the near term, an initial shared ownership model is clearly possible. For example, consider this scenario: A center of excellence may require a patient to spend a week at the center to receive the infusion, as well as for immediate post-infusion monitoring, leaving the community physician to own other parts of the CAR-T patient journey. This shared ownership model could drive market success. In addition, this model could provide late entrants with a unique value proposition to differentiate themselves from early entrants that already have strong relationships in place with centers of excellence, for example.
2. Logistical Excellence
With growing competition and a large addressable patient population, companies that can address logistical and manufacturing issues, with robust, simple supply chains, are expected to win in the CAR-T world. In fact, for the first time in the oncology marketplace, logistic strengths can be sources of sustainable competitive advantage. For example, while turnaround time of treatment options is traditionally a minor factor for contemporary care providers, it likely will become a major one for CAR-T 2.0.
At present, manufacturing the CAR-T cells through reinfusion can take up to 30 days – that is a long time for a critically ill patient seeking treatment options to wait. In addition, first-wave manufacturers are experiencing product variabilities and capacity constraints. These issues are crippling CAR-T 1.0 adoption and already are giving advantage to innovators with better supply chains. Case in point: Novartis had difficulty manufacturing Kymriah due to unspecified product variabilities, which stalled its European Union launch, allowing competitor Gilead to be first to market.
Multiple CAR-T manufacturers are exploring manufacturing enhancements and alternative supply chain structures. Some of the approaches include increased automation and moving away from centralized to point-of-care manufacturing.
If CAR-T 2.0 manufacturers do not address these manufacturing, production, and supply chain issues, they might find themselves left behind, as patients opt for conventional treatments dispensed in real time and competitors with robust systems in place gain preference.
In addition, CAR-T 2.0 manufacturers might find themselves left behind if they ignore the likelihood that hospitals will face disruptions to standard operating procedures across a number of factors, including patient selection, workup, scheduling, admission, care support, discharge planning, and follow up. Manufacturers that conduct provider impact analyses to help hospitals effectively onboard and scale procedures and best practices will have the advantage.
3. Market Access Excellence
Even if CAR-T 1.0 reimbursement and coverage issues are resolved in time for CAR-T 2.0, a host of other challenges looms large.7
First, there will be more competition within CAR-T 2.0 therapy, so 2.0 innovators will have to find a path to coverage and reimbursement and do so while positioning themselves against similar treatments and standards of care options. Manufacturers should prioritize payers as well as regulatory considerations when designing trials and focus on payer-relevant endpoints, such as overall survival in early-stage clinical trials. A properly planned trial with early inclusion of payer-relevant endpoints could eventually lead to mature and robust data by launch, making payers more comfortable covering these expensive therapies. Proactively addressing reimbursement issues, especially in the context of new “shared ownership” models, also will be critical to CAR-T 2.0 success.
Furthermore, as payers get actively involved in managing future CAR-T therapies, manufacturers should start thinking of innovative contracting options, such as performance-based payments, annuity payments, installment payment plans, or risk-sharing agreements to get payer coverage. Innovative payment methods in which cost is related to performance likely will be a way to win in the future.
4. Demonstrate Clear Value Through Evidence Generation
With the large price tag associated with CAR-T therapies and with advancements in conventional therapies, CAR-T therapies need to demonstrate a clear value proposition through the demonstration of clinical benefit over conventional therapies. In the absence of clear clinical benefit, providers will have little motivation to move from a familiar standard of care to a new, unfamiliar one.
For example, to date, initial objective response rate data for CAR-T treatment of relapsed and refractory multiple myeloma is compelling. However, durability of responses remains unknown, as follow-up data is limited.
Furthermore, even if CAR-T therapy for multiple myeloma is very effective, multiple conventional therapies with high success rates also are available. For example, recently daratumumab in combination with Velcade melphalan-prednisone (VMP) was approved for newly diagnosed multiple myeloma patients who are ineligible for autologous stem cell transplant (ASCT). The approval was based on a 90 percent objective response rate in the daratumumab arm compared to the control arm of VMP.8 Now that an effective therapy for newly diagnosed multiple myeloma patients who are ineligible for regenerative ASCT exists, the entry bar for CAR-T therapies will rise for these patients, and endpoints that measure durability of response, such as progression-free survival and overall survival, will be emphasized.
For CAR-T 2.0 markets like multiple myeloma, head-to-head trials to evaluate and demonstrate clinical superiority over on-market therapies will be important validation. With the costs of frontline multiple myeloma triplets and quadruplets likely to be in the $300,000 to $500,000 range,9 CAR-T therapies demonstrating improvements over the competition in earlier lines of therapies will help CAR-T 2.0 therapies gain preferential access.
Winning The CAR-T 2.0 Market
CAR-T 1.0 therapies entered a market that was unprepared for their novelty. CAR-T 2.0 innovators, being next in line, should take the opportunity to learn from the struggles of their novel predecessors, anticipate new and unique high-stakes challenges, and execute on a thoughtful strategy, to help fulfill the tremendous promise of these revolutionary therapies.
