Immunotherapy has transformed cancer care by harnessing the body’s immune system to fight tumors more effectively than traditional methods. These treatments, including checkpoint inhibitors, bispecific antibodies, and cell therapies, offer durable responses and fewer side effects for many patients.
In 2025, significant advancements include new approvals and expansions for PD-1/PD-L1 inhibitors, bispecific T-cell engagers, and combination regimens. Key developments feature subcutaneous formulations for convenience and perioperative uses in early-stage cancers.
These innovations address unmet needs in lung, bladder, gastric, and colorectal cancers, often improving survival in resistant or advanced cases. Biomarker testing guides patient selection, ensuring optimal outcomes. As research integrates immunotherapy with targeted therapies and ADCs, the field continues to expand access and efficacy.
Collaboration between regulators, researchers, and industry drives rapid progress, bringing hope to diverse patient populations.
Overview of Immunotherapy New Medicines in 2025
The term immunotherapy new medicines reflects a dynamic year, with FDA approvals enhancing checkpoint inhibitors and bispecifics. Standouts include Keytruda Qlex (subcutaneous pembrolizumab) approved September 19 for solid tumors, reducing administration time dramatically.
Tarlatamab (Imdelltra) gained full approval November 19 for extensive-stage small cell lung cancer, outperforming chemotherapy. Durvalumab (Imfinzi) became the first perioperative immunotherapy for early gastric/GEJ cancers. Pembrolizumab plus enfortumab vedotin was approved November 21 for cisplatin-ineligible muscle-invasive bladder cancer.
Nivolumab plus ipilimumab expanded for MSI-H/dMMR colorectal cancer. These immunotherapy new medicines emphasize convenience, broader indications, and combinations, with bispecifics like tarlatamab engaging T-cells directly. Priority reviews accelerated access, supported by phase 3 trials showing superior survival and response rates.
Overall, 2025 strengthens immunotherapy’s role across stages and types, prioritizing patient-friendly delivery and multi-modal approaches.

This table highlights transformative approvals.
How These Medicines Work
Immunotherapies unleash immune attacks:
- Checkpoint Inhibitors: Block PD-1/PD-L1 (pembrolizumab, durvalumab) or CTLA-4 (ipilimumab), removing tumor evasion.
- Bispecifics: Tarlatamab bridges T-cells to DLL3 on cancer cells, triggering direct killing.
- Combinations: Pair with ADCs (enfortumab vedotin) for enhanced targeting and immune activation.
Perioperative use prevents recurrence by addressing microscopic disease.
Benefits and Patient Impact
New medicines improve convenience and outcomes. Subcutaneous Keytruda Qlex cuts treatment time to minutes. Tarlatamab extends survival in aggressive SCLC. Perioperative durvalumab offers first immunotherapy for curable gastric cancers. Combinations reduce risks in bladder/colorectal. Overall, higher response rates, longer remission, and better tolerability empower patients, especially in advanced or ineligible cases.
Side Effects and Management
Immune-related events common:
- Rash, thyroid issues: Monitored, treated with steroids.
- Cytokine release (bispecifics): Pretreated, supportive care.
- Fatigue, diarrhea: Dose adjustments.
Multidisciplinary teams manage effectively.
Future Outlook
2026 anticipates more bispecifics, vaccines, and personalized combos.
