What's Behind the Drop in ADC Therapeutics' Stock?
ADC Therapeutics SA (NYSE: ADCT) is currently facing a significant decline in its market value as investors react to the latest updates regarding their cancer treatment, Zynlonta. Despite presenting promising data from its ongoing LOTIS-7 clinical trial, the stock has taken a hit due to rising concerns about the medication's safety profile and the overall progression of the trial.
Recent Trial Results
The company recently provided an update related to the LOTIS-7 Phase 1b open-label trial. This involves Zynlonta being administered in conjunction with glofitamab (Columvi) as a treatment for relapsed or refractory diffuse large B-cell lymphoma (r/r DLBCL). Investors had anticipated positive news; however, some elements of the findings led to disappointment.
Understanding the Key Data Findings
During the recent announcement, ADC Therapeutics highlighted several key data points. As of the last cutoff date, a total of 49 patients had been evaluated for efficacy, with a minimum follow-up of six months. The results included a best overall response rate (ORR) of 89.8%, showcasing that out of 49 patients, 44 responded to the treatment. The complete response rate was also favorable at 77.6%, with 38 patients achieving a complete response.
Patient Outcomes and Safety Concerns
Of the patients who achieved a complete response, 33 remained in that state by the data cutoff. Concerns arose over five patients who were no longer in complete response; two had progressive disease, and two experienced significant adverse events during their response period. This information raised red flags for potential investors.
Efficacy Across Patient Populations
The trial results demonstrated strong efficacy across both relapsed and primary refractory populations, which is crucial for the drug's potential market acceptance. Among the 24 patients previously treated for relapsed conditions, the ORR was perfect at 100%, with a complete response rate of 91.7%. For the 25 patients categorized as primary refractory, the ORR stood at a commendable 80%, with a 64% rate of complete response.
Trial Enrollment and Future Plans
Ongoing enrollment for the LOTIS-7 trial remains a priority for ADC Therapeutics, with an expectation to complete recruitment of approximately 100 patients for the selected dose of 150 µg/kg in the first half of the following year. The company aims to present comprehensive data at a forthcoming medical convention and submit findings for publication by year-end.
Current Stock Performance of ADC Therapeutics

Such price action reflects the cautious approach investors are taking in light of uncertain trial outcomes, despite the potential therapeutic benefits of Zynlonta.
