Antibody-drug conjugates are expanding from late-line to first-line combination regimens in lung cancerNew Drug Class Shifts Lung Cancer Treatment Toward First-Line Use

Key Takeaway
Note the expanding role of ADCs in first-line lung cancer, though many strategies require confirmation in larger trials.

This narrative review synthesizes the evolving landscape of antibody-drug conjugates (ADCs) for the treatment of non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). The review focuses on ADCs targeting a wide range of antigens, including TROP2, HER2, Nectin-4, PD-L1, c-Met, B7-H3, DLL3, and SEZ6, as well as combination therapies involving ADCs and immune checkpoint inhibitors.

The primary finding is the expansion of ADC-based strategies from later-line treatments toward first-line combination regimens. This shift reflects an expanding ADC landscape in the management of lung cancer.

The authors note significant limitations regarding the current evidence base. Many emerging strategies are supported primarily by preliminary conference-reported or early-phase data. These findings require confirmation in mature peer-reviewed studies and adequately powered randomized clinical trials. Clinical application of these early-phase data should be interpreted with caution until more robust evidence is available.

How this fits prior evidence

This narrative review expands upon previous evidence regarding ADCs in small cell lung cancer, which showed a 25.7% objective response rate in advanced cases but were associated with frequent clinically important toxicity. While previous reports focused on later-line ADC use, this review highlights a shift toward first-line combination regimens in both NSCLC and SCLC. It also addresses the broader landscape of targets beyond those previously discussed, such as TROP2 and B7-H3.

For people with lung cancer, the hardest part is often that treatments run out. You try one, then another, and each time the cancer finds a way back. Now, a new class of drugs called antibody-drug conjugates (ADCs) is changing that story. Instead of being saved for later, these drugs are being tested as first-line treatments, right from the start.

ADCs work like guided missiles. They attach to specific proteins on cancer cells and deliver a strong chemotherapy payload directly to the tumor. In this review, researchers looked at ADCs targeting proteins like TROP2, HER2, Nectin-4, PD-L1, c-Met, B7-H3, DLL3, and SEZ6 in non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). They also explored combining ADCs with immune checkpoint inhibitors, another type of cancer drug.

The big idea is that ADCs could move from later-line treatment, after other drugs fail, to first-line combination regimens. That could mean more options earlier for patients. But there is a catch. Many of these strategies are still in early testing, often reported only at conferences, not yet in peer-reviewed studies. They need confirmation in larger, randomized trials before we know if they truly help people live longer or better.

So while the direction is promising, it is not yet proven. For now, this is a sign of progress, not a guarantee. If you or a loved one are facing lung cancer, talk with your doctor about what is known and what is still experimental.

What this means for you:
Antibody-drug conjugates are moving earlier in lung cancer treatment, but early data need confirmation.

Common questions

What are antibody-drug conjugates?

Antibody-drug conjugates are a new type of cancer drug. They use an antibody to find specific proteins on cancer cells and deliver a strong chemotherapy directly to the tumor. This review looked at ADCs targeting proteins like TROP2, HER2, and others in lung cancer.

Are these new lung cancer treatments safe?

The review does not report safety details like side effects or serious adverse events. Because many of these strategies are still in early testing, safety needs to be confirmed in larger studies. Talk to your doctor about the risks and benefits of any treatment.

Who might benefit from antibody-drug conjugates?

The review focuses on patients with non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). It suggests ADCs could move from later-line treatment to first-line combination regimens, but this is not yet proven in large trials.

How is this different from current lung cancer treatment?

Currently, many new treatments are used after other drugs fail. This review highlights a shift toward using ADCs earlier, possibly in combination with immune checkpoint inhibitors. However, most evidence comes from early-phase or conference-reported data, so it is not yet standard practice.

The 2026 American Society of Clinical Oncology (ASCO) Annual Meeting presented substantial new data on antibody–drug conjugates (ADCs) in lung cancer, highlighting the ongoing expansion of ADC-based strategies from later-line treatment toward first-line combination regimens. This focused narrative review summarizes and discusses the efficacy and safety findings of ADCs targeting TROP2, HER2, Nectin-4, PD-L1, c-Met, B7-H3, DLL3, SEZ6, and other emerging targets in non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC), with particular attention to emerging ADC plus immune checkpoint inhibitor combinations in the first-line setting. Taken together, these findings highlight an expanding ADC landscape in lung cancer. However, many of the emerging strategies remain supported primarily by preliminary conference-reported or early-phase data and therefore require confirmation in mature peer-reviewed studies and adequately powered randomized clinical trials.
