ADC Therapeutics (ADCT) Q2 2025: Lotus 7 Delivers 87% Complete Response Rate, Reshaping DLBCL Market Path

ADC Therapeutics’ Q2 revealed a pivotal inflection in its lymphoma franchise, as Lotus 7 data showed an 86.7% complete response rate in combination therapy, outpacing industry benchmarks and positioning Zynlonta for major expansion in the DLBCL market. A strategic refocus on core programs, cost discipline, and a $100 million capital raise extend the cash runway through 2028, setting up multiple value-driving catalysts ahead. Investors now face a transformed risk-reward profile, with regulatory milestones and competitive read-throughs in the spotlight for the coming year.

Summary

  • Lotus 7 Combination Efficacy Surges: ADC’s Zynlonta plus glofitamab posted an 87% complete response rate, far above peer regimens.
  • Strategic Refocus and Cost Actions: Early-stage programs were discontinued and headcount reduced by 30% to prioritize lead assets and extend cash runway.
  • Upcoming Catalysts Will Define Trajectory: Regulatory discussions, expanded data readouts, and Lotus 5 topline results are set to drive valuation and market access decisions.

Performance Analysis

ADC Therapeutics delivered a quarter marked by clinical outperformance and operational streamlining. Net product revenue for Zynlonta, the company’s antibody-drug conjugate for third-line plus diffuse large B-cell lymphoma (DLBCL), showed modest year-over-year growth. The topline was supported by continued adoption in its approved indication, but the real inflection came from clinical trial data: Lotus 7’s Zynlonta plus glofitamab combination achieved a 93.3% overall response rate and an 86.7% complete response rate across 30 efficacy-evaluable patients, with durability signals exceeding historical benchmarks.

Operating expenses increased 8% year-over-year on a non-GAAP basis, driven by R&D investment in pivotal Lotus 5 and 7 trials and IND-enabling work for the PSMA-targeting ADC. The quarter included $13.1 million in restructuring and impairment charges as ADC wound down non-core preclinical programs and initiated a 30% workforce reduction, aligning spending with strategic priorities. The company secured a $100 million private placement, boosting cash and equivalents to $264.6 million and extending the runway into 2028, even as net loss widened due to one-time charges and higher R&D.

  • Clinical Differentiation Surfaces: Lotus 7’s complete response rate is well above the 47–62% range seen in other bispecific combination trials, with 25 of 26 CRs maintained at cutoff.
  • Cost Structure Realigned: Discontinuation of early-stage solid tumor programs and UK site closure will materially reduce future burn, focusing resources on high-probability assets.
  • Balance Sheet Reinforced: The private placement offsets restructuring costs, giving ADC time to pursue regulatory approvals and commercial expansion without near-term capital risk.

With multiple shots on goal in DLBCL and indolent lymphomas, ADC’s financial and operational posture now hinges on execution of pivotal trials, regulatory engagement, and commercial readiness for broader indications.

Executive Commentary

"We are encouraged by the promising data which we believe demonstrates the potential for Zinlanta plus Glofetamab to be a best-in-class combination in a highly competitive market."

Strategic Positioning

1. Zynlonta as a Combination Backbone

ADC is positioning Zynlonta as the backbone for combination regimens in DLBCL, leveraging its manageable safety profile and rapid, durable efficacy. The Lotus 7 trial with glofitamab, a bispecific antibody, is designed to capture both “complex” and “broadly accessible” therapy segments, reflecting a nuanced understanding of treatment infrastructure and physician adoption patterns.

2. Market Expansion Beyond Third-Line DLBCL

The company’s strategy targets major market expansion into second-line DLBCL and indolent lymphomas, with Lotus 5 (Zynlonta plus rituximab) and IIT studies in marginal zone lymphoma (MZL) and follicular lymphoma. Management estimates U.S. peak revenue potential of $600 million to $1 billion, with second-line entry and compendia listing as critical milestones.

3. Focused Pipeline and Cost Discipline

ADC has dramatically narrowed its pipeline, discontinuing all early-stage solid tumor programs to concentrate on Zynlonta and a preclinical PSMA-targeting ADC. This focus, along with the 30% workforce reduction and UK facility closure, is expected to materially lower operating expenses and align R&D investment with the most de-risked, value-driving assets.

4. Regulatory and Commercial Execution

Regulatory strategy is front and center, with Lotus 5 data expected by year-end, a supplemental BLA planned for first half 2026, and confirmatory approval possible in 2027. ADC is also prioritizing compendia listing for Lotus 7, which would enable broader off-label adoption ahead of full approval. The commercial footprint already covers 90% of DLBCL volume, with additional resources planned for launch phases.

5. Data-Driven Differentiation

Durability and depth of response are key differentiators, with ADC emphasizing high complete response rates and long-term remission durability as benchmarks for regulatory and commercial success. Upcoming data updates will be critical in validating these claims and supporting guideline inclusion.

Key Considerations

This quarter marks a strategic pivot for ADC Therapeutics, as the company doubles down on its most promising assets and prepares for a series of high-stakes clinical and regulatory milestones. Investors should weigh the magnitude of the Lotus 7 efficacy signal against execution and competitive risks, especially as the DLBCL landscape evolves with new entrants and shifting guidelines.

Key Considerations:

  • Clinical Outperformance Raises Bar: Lotus 7’s 87% CR rate, if durable, could reset expectations for combination regimens in aggressive lymphoma.
  • Execution on Regulatory Pathways: Timely engagement with FDA and successful compendia listing will be pivotal to unlocking second-line and broader market access.
  • Cost Structure Now Aligned to Core Programs: The 30% workforce reduction and program discontinuations should materially improve operating leverage post-2025.
  • Cash Runway Mitigates Near-Term Dilution Risk: With funding into 2028, ADC has time to deliver on pivotal readouts without immediate capital pressure.
  • Competitive and Regulatory Overhangs Persist: Recent FDA actions (e.g., Roche’s complete response letter) introduce market uncertainty that could impact ADC’s path to approval and commercial uptake.

Risks

ADC faces several material risks, including regulatory uncertainty as seen with recent FDA decisions in the DLBCL space, potential for efficacy or safety data to regress with longer follow-up, and execution risk around pivotal trial readouts and commercial scaling. Competitive dynamics remain intense, with multiple bispecifics and ADCs vying for guideline inclusion and market share. Any delays or negative surprises in Lotus 5 or 7 could significantly alter the company’s revenue trajectory and valuation.

Forward Outlook

For Q3 and remainder of 2025, ADC guided to:

  • Lotus 5 to reach pre-specified progression-free survival events by year-end, with top-line data to follow.
  • Additional mature Lotus 7 data and regulatory engagement with FDA and compendia bodies in the second half.

For full-year 2025, management expects:

  • Operating expenses to trend lower as Lotus 5 investment declines and cost actions take effect.
  • Cash runway to extend into 2028, supporting multiple catalysts and reducing dilution risk.

Management highlighted that data durability, regulatory feedback, and commercial readiness are the primary levers for value creation in the next 12–18 months.

  • Lotus 5 and 7 data updates are expected at medical congresses or company events.
  • Engagement with FDA and NCCN will determine speed and scope of market expansion.

Takeaways

ADC’s Q2 marks a decisive advance in its clinical and commercial positioning, but the next year will be defined by the durability of Lotus 7 results, Lotus 5 regulatory progress, and the company’s ability to translate clinical data into market share amid a dynamic competitive landscape.

  • Lotus 7 Efficacy Is a Game Changer: The 87% complete response rate, if sustained, could make Zynlonta plus glofitamab the preferred regimen for second-line plus DLBCL, driving upside to current revenue forecasts.
  • Strategic Refocus Strengthens Fundamentals: Discontinuing non-core programs and reducing headcount positions ADC to maximize the impact of its lead assets and extend its cash runway.
  • Investor Focus Should Pivot to Data Maturity and Regulatory Progress: The next 12 months will clarify whether ADC can convert its clinical edge into commercial dominance and durable shareholder value.

Conclusion

ADC Therapeutics enters a high-stakes phase with strong clinical signals and a streamlined cost base, but faces critical execution and regulatory hurdles. The company’s ability to deliver on pivotal data, secure regulatory wins, and scale commercially will determine whether it captures the full value of its DLBCL franchise.
