8-K: ADC Therapeutics Outlines Strategy, Highlights Promising Clinical Data at Industry Conferences

ADC Therapeutics provides an update on its clinical programs, financial strategy, and research pipeline, emphasizing its focus on hematology and solid tumor treatments.

Summary

• ADC Therapeutics is focusing on maximizing ZYNLONTA in hematology, particularly in Diffuse Large B-Cell Lymphoma (DLBCL), and advancing ADCT-601 in solid tumors.
• The company anticipates a cash runway into mid-2026, assuming receipt of regulatory milestone payments and adherence to loan agreement terms.
• ZYNLONTA is being explored in combination therapies, including LOTIS-5 with rituximab and LOTIS-7 with bispecific antibodies, showing promising early results.
• ADCT-601, targeting AXL, is undergoing dose optimization in sarcoma, pancreatic, and non-small cell lung cancer (NSCLC) with early signs of anti-tumor activity.
• The company is also developing next-generation Antibody-Drug Conjugates (ADCs) with a novel exatecan-based payload and hydrophilic linker.
• Initial data from investigator-initiated trials (IITs) suggest ZYNLONTA could be beneficial in indolent lymphomas, with high overall response rates (ORR) and complete response rates (CR) in follicular lymphoma (FL) and marginal zone lymphoma (MZL).
• The company is pursuing a partnership and collaboration strategy to support the progression of its early-stage portfolio and secure non-dilutive capital.
• ADC Therapeutics is aiming for commercial brand profitability for ZYNLONTA in 2024 and anticipates several clinical data updates in the second half of 2024 and first half of 2025.

Industry Context

The company is operating in a competitive landscape with other companies developing novel cancer therapies, particularly in the areas of lymphoma and solid tumors. The company is focusing on combination therapies and next-generation ADCs to differentiate itself.

Comparison to Industry Standards

• The LOTIS-5 trial's 80% ORR and 50% CR in the safety run-in compares favorably to standard immunochemotherapy in relapsed/refractory DLBCL.
• The 96% ORR and 85% CR observed in the IIT for ZYNLONTA plus rituximab in high-risk relapsed/refractory FL are higher than the ORR of 78% and 79% seen with Lenalidomide plus Rituximab (R2) and Bendamustine plus Obinutuzumab respectively.
• The 13 out of 15 complete responses in the MZL IIT are notable compared to the less than 30% CR for 2L+ NCCN preferred treatments.
• The exatecan-based ADC platform is differentiated from other ADC platforms using DXd, with preclinical data suggesting better potency and a superior therapeutic index.
• The company's focus on combination therapies aligns with the trend of using off-the-shelf agents in lymphoma treatment.

Stakeholder Impact

• Shareholders may benefit from the positive clinical data and potential for future growth.
• Employees may be motivated by the company's progress and future prospects.
• Patients may benefit from the development of new and effective cancer treatments.
• Partners may benefit from the company's strong research and development capabilities.

Next Steps

• Complete enrollment in the LOTIS-5 trial in 2024.
• Provide initial efficacy/safety update for LOTIS-7 Part 2 with glofitamab in 2H 2024.
• Provide additional data updates for ADCT-601 and ADCT-602 in 2H 2024.
