Key Terms

antibody drug conjugates, diffuse large B-cell lymphoma, overall response rate, complete response rate, +4 more

8 terms

antibody drug conjugates medical

"a commercial-stage global leader and pioneer in the field of antibody drug conjugates (ADCs)"

Antibody drug conjugates are targeted medicines that combine an antibody, which seeks out specific markers on diseased cells, with a powerful drug that is released only when the antibody binds its target. Think of it as a guided missile that delivers a toxic payload directly to its target, reducing damage to healthy cells; investors watch them because successful ADCs can offer high-value, niche treatments and drive strong revenue and patent-based protection for developers.

diffuse large B-cell lymphoma medical

"patients with relapsed or refractory diffuse large B-cell lymphoma (r/r DLBCL)"

A fast-growing form of blood cancer that starts in white blood cells within the lymphatic system and can spread quickly to other organs. Investors watch it because the need for effective treatments, the size of the patient population, and results from clinical trials or regulatory approvals can significantly affect pharmaceutical and biotech company revenues—think of it like a large, urgent market for new medicines where trial results or approvals can move stock prices.

overall response rate medical

"demonstrated an 89.8% best overall response rate (ORR) and a 77.6% complete response"

Overall response rate is the percentage of patients in a clinical study whose measurable disease shrinks or disappears after receiving a treatment. Investors watch it like a product’s “hit rate” because higher response rates can signal a drug’s effectiveness, boost chances of regulatory approval and market demand, and affect a company’s future revenue prospects, similar to how a higher batting average suggests a more reliable player.

complete response rate medical

"best overall response rate (ORR) and a 77.6% complete response rate across 49"

Complete response rate is the percentage of patients in a clinical trial whose measurable signs of disease disappear after treatment, as judged by predefined medical tests. For investors, a higher complete response rate is a strong signal that a drug works well in the trial setting, improving chances of regulatory approval and commercial success — like seeing most lightbulbs in a new batch actually turn on before deciding to buy the factory.

progression-free survival medical

"once the pre-specified number of approximately 262 progression-free survival (PFS) events"

Progression-free survival is the length of time during and after a treatment that a patient's disease does not get worse, measured from the start of treatment until the disease shows measurable signs of progression or the patient dies. Investors care because longer progression-free survival in clinical trials often signals that a drug is effective, improving chances of regulatory approval, market adoption, and revenue potential—think of it as a stopwatch showing how long a therapy can keep the illness at bay.

supplemental biologics license application regulatory

"a supplemental Biologics License Application (sBLA) submission to the U.S. FDA will follow"

A supplemental biologics license application is a formal request to a regulator (such as the U.S. Food and Drug Administration) asking permission to change an already approved biological product — for example to add a new use, change how it’s made, or alter dosing. For investors, an approved supplemental application can expand a product’s sales or reduce manufacturing risk, while a delay or rejection can limit revenue prospects or raise compliance costs; think of it like applying for an update to a building permit for an existing, income-producing property.

investigator-initiated trials medical

"Investigator-initiated trials (IITs) of ZYNLONTA in indolent lymphomas ongoing"

Clinical studies designed and run by independent physicians or academic researchers rather than by a drug or device company; the investigator shapes the question, protocol and oversight and may use an existing therapy or a company’s product with permission. For investors, these trials can reveal new uses, safety signals or early effectiveness at relatively low cost to companies, like a third-party test drive that can boost or dim a product’s commercial prospects and affect development timelines and valuation.

prostate-specific membrane antigen medical

"exatecan-based, prostate-specific membrane antigen (PSMA)-targeting ADC were completed"

A protein that sits on the surface of prostate cells, often much more abundant on prostate cancer cells, used as a biological “flag” that diagnostic scans and targeted treatments can home in on. Investors care because products that detect or bind this marker—like imaging agents or targeted drugs—can improve diagnosis and therapy, create new revenue streams, and face regulatory milestones that materially affect a company’s value.

Preliminary unaudited fourth quarter and full year 2025 net product revenue of approximately $22M and $73M respectively; cash and cash equivalents of approximately $261M as of December 31, 2025, provide expected cash runway at least to 2028

Anticipated near-term catalysts include LOTIS-7 complete enrollment in first half of 2026 and LOTIS-5 Phase 3 topline data in second quarter 2026

Additional anticipated catalysts include full LOTIS-5 and LOTIS-7 results by end of 2026, with potential compendia inclusions in first half of 2027 and LOTIS-5 regulatory approvals to follow

LAUSANNE, Switzerland, Jan. 8, 2026 /PRNewswire/ -- ADC Therapeutics SA (NYSE: ADCT), a commercial-stage global leader and pioneer in the field of antibody drug conjugates (ADCs), today provided corporate updates and highlights from its ZYNLONTA® clinical program.

"During 2025, we delivered meaningful progress across our ZYNLONTA clinical program and extended our expected cash runway at least to 2028," said Ameet Mallik, Chief Executive Officer of ADC Therapeutics. "This year, we look forward to multiple clinical catalysts including full results from our LOTIS-5 and LOTIS-7 2L+ DLBCL trials, as well as potentially from the ongoing Phase 2 indolent lymphoma IITs. Assuming positive results, we anticipate potential compendia inclusion for each in the first half of 2027 with LOTIS-5 regulatory approvals to follow. Taken together, we anticipate we will see an acceleration in net product revenue growth beginning in 2027."

Recent Highlights and Developments

Preliminary unaudited 2025 selected financial results. ZYNLONTA net product revenue is expected to be approximately $73 million for full year 2025 compared with $69.3 million for full year 2024. Fourth quarter 2025 ZYNLONTA net product revenue is expected to be approximately $22 million, as compared to $16.4 million in the fourth quarter of 2024, primarily reflecting variability in customer ordering. Underlying demand for ZYNLONTA in the current 3L/3L+ DLBCL indication remained broadly stable year-over-year. The Company ended 2025 with cash and cash equivalents of approximately $261 million which, based on current plans, is expected to provide a cash runway at least to 2028.

Reported updated data from LOTIS-7 in December 2025. Updated data from the LOTIS-7 Phase 1b clinical trial evaluating the safety and efficacy of ZYNLONTA in combination with the bispecific antibody glofitamab (COLUMVI®) in patients with relapsed or refractory diffuse large B-cell lymphoma (r/r DLBCL) demonstrated an 89.8% best overall response rate (ORR) and a 77.6% complete response rate across 49 efficacy evaluable patients with a minimum of 6 months follow-up. Enrollment in the LOTIS-7 trial is ongoing, with complete enrollment of approximately 100 patients at the selected 150 µg/kg dose expected during the first half of 2026. The Company plans to share full data at a medical meeting and through publication by the end of 2026. In addition, the Company plans to assess regulatory and compendia strategies in the first half of 2027.

LOTIS-5 topline results anticipated in 2Q 2026. The Company expects to provide topline data in 2Q 2026 from the LOTIS-5 Phase 3 confirmatory trial of ZYNLONTA in combination with rituximab in patients with 2L+ DLBCL once the pre-specified number of approximately 262 progression-free survival (PFS) events is reached and data are available. Publication of the full results is anticipated by the end of 2026. Assuming positive results, a supplemental Biologics License Application (sBLA) submission to the U.S. FDA will follow, with potential compendia inclusion in the first half of 2027 and confirmatory approval in 2L+ DLBCL in mid-2027.

Investigator-initiated trials (IITs) of ZYNLONTA in indolent lymphomas ongoing. Initial data from the Phase 2 clinical trial evaluating ZYNLONTA in combination with rituximab to treat relapsed or refractory (r/r) follicular lymphoma (FL) and the Phase 2, single-arm, open-label, multicenter trial of ZYNLONTA to treat r/r marginal zone lymphoma (MZL) led by the Sylvester Comprehensive Cancer Center at University of Miami have shown promising efficacy and manageable safety results. The Company anticipates publication of both data sets as early as the end of 2026. Assuming positive data, the Company plans to assess regulatory and compendia strategies.

IND-enabling activities completed for PSMA-targeting ADC. IND-enabling activities for the Company's exatecan-based, prostate-specific membrane antigen (PSMA)-targeting ADC were completed at the end of 2025. The Company continues to explore partnership opportunities.
