Future Outlook

The company expects its cash runway to extend into the fourth quarter of 2025 and anticipates multiple value-generating catalysts in 2024, including achieving commercial brand profitability for ZYNLONTA, completing enrollment in the LOTIS-5 trial, and providing updates from the LOTIS-7 and ADCT-601 trials.

Management Comments

• Ameet Mallik, Chief Executive Officer, stated that the company reset its business and capital allocation strategy in 2023, strengthened the team, and established a clear roadmap to drive value creation.
• Ameet Mallik also noted that the impact of the new commercial model resulted in a resumption of growth for ZYNLONTA sales volume compared to the third quarter.
• Management is confident that they have the right team and strategy to grow ZYNLONTA in 3L/3L+ DLBCL.

Industry Context

This announcement comes as the oncology market is seeing increased competition and a shift towards combination therapies. ADC Therapeutics is positioning ZYNLONTA as a key component in these combinations, particularly in the second and third-line treatment of DLBCL, and is also exploring its potential in other B-cell lymphomas. The company's focus on a novel exatecan-based ADC platform also aligns with the industry's push for more effective and less toxic cancer treatments.

Comparison to Industry Standards

• The 17% sequential growth in ZYNLONTA sales in Q4 2023 indicates a positive response to the new commercial model, which is a key metric for pharmaceutical companies launching new products.
• The 21% reduction in operating expenses demonstrates a commitment to financial efficiency, which is crucial for biotech companies with high R&D costs.
• The cash runway extending into Q4 2025 provides a longer period of financial stability compared to many other biotech companies, which often have shorter cash runways.
• The LOTIS-5 trial's potential need for additional enrollment due to higher-than-expected censoring is a common challenge in clinical trials, highlighting the complexities of drug development.
• The early signs of anti-tumor activity in the ADCT-601 trial are promising, but further data is needed to compare its efficacy to other AXL-targeted therapies in development.
• The investigator-initiated trial results for ZYNLONTA in FL are very strong, with a 96.3% ORR and 85.2% CR, which is competitive with other treatments in this space.
• The development of a novel exatecan-based ADC platform is a strategic move to differentiate from competitors using more established payloads like DXd, which is used by companies such as Daiichi Sankyo and AstraZeneca.
