Legend Biotech, the rising star of the CAR-T therapy world, has been enjoying remarkable success. Following a series of regulatory approvals for CARVYKTI, their breakthrough treatment for multiple myeloma, the company projects a bright future, aiming for billion-dollar peaks and expanding patient capacity. However, lurking beneath this optimistic narrative, a hidden threat could potentially disrupt their ambitious growth: an over-reliance on external manufacturing partners.

While Legend celebrates the progress of their internal manufacturing capabilities, including the impressive Tech Lane facility in Ghent, Belgium, and the newly operational Obelisc site, their continued dependence on external partners like Novartis remains a significant vulnerability. This reliance isn't just a temporary solution; it's a key component of their plan to reach a capacity of 10,000 patient slots by the end of 2025. This is where the danger lies.

Outsourcing manufacturing offers advantages like rapid scaling and lower upfront investment, but it also carries inherent risks. Legend sacrifices control over quality, production schedules, and even pricing, leaving them vulnerable to external factors they can't directly manage. Any delay in Novartis's IND filing, for example, could disrupt Legend's entire production schedule, potentially jeopardizing their ability to meet the increasing demand for CARVYKTI, particularly in the recently approved second-line setting.

This dependence becomes even more concerning when considering the competitive landscape. A competitor, also facing an FDA advisory committee review, has opted for internal manufacturing expansion. While this involves higher initial costs, the long-term benefits of having complete control over their production are undeniable.

Projected Manufacturing Capacity Expansion

This chart, based on Legend Biotech's Q1 2024 earnings call, visualizes the planned capacity expansion. Note that the Obelisc commercial production timeline is uncertain, projected for late Q3 or early Q4 2024.

Let's delve into the figures. Legend aims to double their manufacturing capacity by the end of 2024, primarily driven by anticipated commercial production from the Obelisc facility. The timing of this commercial production remains uncertain, estimated to be sometime in late Q3 or early Q4. Any delay in this schedule could significantly impact their revenue growth in the second half of the year.

Adding another layer of complexity, Legend relies on Novartis for clinical production of CARVYKTI for the CARTITUDE-6 trial, freeing up internal capacity for commercial production. While Legend projects commercial production from Novartis to begin in early 2025, the successful completion of clinical trials and subsequent regulatory approvals are crucial milestones that could encounter unforeseen delays.

The ambitious target of 10,000 patient slots by the end of 2025 becomes particularly worrisome when considering potential manufacturing challenges. This target, a significant leap from their current capacity, hinges on the successful and timely execution of multiple manufacturing expansions, both internal and external. A single setback in this complex network could derail their entire production plan, potentially leading to supply shortages and impacting their ability to capitalize on the expanding market for CARVYKTI.

The financial implications are substantial. Legend projects profitability in 2026, contingent upon their successful penetration into the second-line setting and a robust growth trajectory for CARVYKTI. However, this projection relies heavily on their ability to consistently supply the therapy to a rapidly expanding patient population. Any disruption in manufacturing could directly impact revenue growth, potentially delaying their path to profitability and jeopardizing their long-term financial stability.

Consider this hypothetical scenario: Novartis faces regulatory hurdles with their IND filing, delaying clinical trial production of CARVYKTI for the CARTITUDE-6 trial by six months. Combined with a hypothetical three-month delay in Obelisc's commercial production, Legend's ability to meet the projected demand for CARVYKTI in the second-line setting would be severely hampered, potentially leading to a revenue shortfall of $100 million or more in 2025. This, coupled with the potential need for additional capital investment to address manufacturing bottlenecks, could easily push their profitability timeline beyond 2026.

The stakes are high. While Legend Biotech's current success story is compelling, their reliance on external manufacturing partners introduces a level of vulnerability that cannot be overlooked. Investors need to closely scrutinize the execution of Legend's manufacturing expansion plans, recognizing the potential for delays and disruptions that could impact their growth trajectory and long-term financial health. Legend's success hinges on their ability to navigate this manufacturing minefield, ultimately proving whether they can truly ascend to the throne of the CAR-T therapy kingdom.

"Fun Fact: The name "Legend" was chosen to reflect the company's aspiration to create legendary therapies that transform patient lives. It's a bold vision, but one that could be undermined by a lack of complete control over their own destiny."
