Reporting period: Form 6-K furnished for July 2022; dated July 20, 2022. The filing reports a clinical-development update rather than financial results.
Business Context
ADC Therapeutics is a commercial-stage biotechnology company developing antibody-drug conjugates for hematologic malignancies and solid tumors.

Key Financial Metrics and Liquidity
- The filing does not provide revenue, profit or loss, cash flow, margin, debt, liquidity, cash-balance or other financial metrics.
- The filing does not provide updated financial guidance or projections.
Material Operational Update
- ADC Therapeutics announced that the first patient had been dosed in LOTIS-9, an open-label Phase 2 trial evaluating ZYNLONTA in combination with rituximab, or Lonca-R.
- The trial targets previously untreated, unfit and frail patients with diffuse large B-cell lymphoma, including patients aged 80 years or older, an underserved population that may be ineligible for standard R-mini-CHOP therapy.
- The initial exploratory stage is expected to evaluate approximately 80 patients assigned to an unfit cohort or a frail cohort using a simplified geriatric assessment.
- The response-adapted treatment design provides three initial cycles of Lonca-R, with additional cycles based on complete response, partial response or, in limited circumstances, stable disease and clinical benefit.
Pipeline, Outlook and Risks
- ZYNLONTA is also being evaluated in combination studies and earlier lines of therapy. The company is additionally developing camidanlumab tesirine and other ADC candidates.
- ZYNLONTA’s U.S. approval for relapsed or refractory large B-cell lymphoma was granted under the FDA’s accelerated-approval pathway. Continued approval may depend on verification and description of clinical benefit in a confirmatory trial.
- The filing’s forward-looking statements include expectations regarding clinical trials, regulatory approvals, commercial strategy, market opportunities, revenues, expenses and the timing and likelihood of success.
- Management cautioned that clinical, regulatory, commercial and other risks could cause actual results to differ materially from forward-looking statements. The filing refers investors to the company’s SEC filings for additional risk factors.
Important Facts for Investors to Verify
- Enrollment progress, patient numbers and efficacy and safety results from LOTIS-9.
- Whether the trial achieves its response and tolerability objectives in unfit and frail patients.
- The status of confirmatory testing and FDA requirements supporting continued accelerated approval of ZYNLONTA.
- ADC Therapeutics’ latest cash position, operating cash burn, debt obligations, revenue from ZYNLONTA and available financing, which are not provided in this Form 6-K.
