Targeted therapies represent a cornerstone of modern oncology pharmacology, designed to interfere with specific molecular pathways essential for cancer cell growth, progression, and survival, while minimizing harm to healthy cells. This approach necessitates robust oncology pharmacology diagnosis and staging capabilities, particularly molecular profiling to identify actionable mutations.

• Tyrosine Kinase Inhibitors (TKIs): First-generation TKIs (e.g., imatinib for CML, gefitinib/erlotinib for EGFR-mutated NSCLC) demonstrated the power of precision medicine. By 2025, the landscape has diversified to include a plethora of TKIs targeting various oncogenic drivers such as ALK (alectinib, lorlatinib), ROS1, RET (selpercatinib, pralsetinib), and BRAF/MEK (dabrafenib/trametinib for melanoma and specific thyroid/colorectal cancers). The challenge lies in managing acquired resistance, leading to the development of next-generation TKIs (e.g., osimertinib for EGFR T790M mutation) that overcome common resistance mechanisms, significantly impacting oncology pharmacology management strategies. Recent updates from ASCO 2025 have shown promising results for novel BRAF-mutated metastatic colorectal cancer treatments, with three-drug combinations like encorafenib plus cetuximab, with or without chemotherapy, demonstrating improved progression-free and overall survival.

• Antibody-Drug Conjugates (ADCs): ADCs have emerged as a powerful class of targeted agents, combining the specificity of monoclonal antibodies with the potency of cytotoxic chemotherapy. They act as "guided missiles," delivering a cytotoxic payload directly to cancer cells expressing a specific target antigen. Recent approvals and advanced oncology pharmacology clinical trials for ADCs like trastuzumab deruxtecan (T-DXd for HER2-low and HER2-positive breast cancer, and expanded use in NSCLC by early 2025), datopotamab deruxtecan (Dato-DXd for HR-positive, HER2-negative breast cancer and NSCLC with EGFR mutations), and sacituzumab govitecan (Trodelvy for mTNBC) showcase their broad utility. These agents highlight the need for specialized knowledge regarding their unique oncology pharmacology side effects, such as interstitial lung disease with T-DXd, which requires careful monitoring by oncology pharmacology for physicians.

• Other Targeted Modalities: Beyond TKIs and ADCs, the targeted therapy landscape includes PARP inhibitors (e.g., olaparib for BRCA-mutated ovarian, breast, and prostate cancers), which exploit DNA repair deficiencies, and selective estrogen receptor degraders/modulators (SERDs/SERMs) for hormone receptor-positive breast cancers. The 2025 period also sees increasing focus on challenging targets like KRAS (sotorasib, adagrasib) and new therapeutic classes like HIF2-alpha inhibitors (belzutifan for VHL-associated tumors).

2.2. Immunopharmacology: Unleashing the Immune System

Immunotherapy, particularly immune checkpoint inhibitors (ICIs), has revolutionized cancer treatment across numerous solid tumors and hematological malignancies. These agents block immune checkpoints (e.g., PD-1, PD-L1, CTLA-4), thereby unleashing the patient's endogenous anti-tumor immune response.

• Immune Checkpoint Inhibitors (ICIs): Pembrolizumab (Keytruda) and nivolumab (Opdivo) remain leading examples, with expanded indications now covering a wide array of cancers, often in combination with chemotherapy or other targeted agents. Updates from ASCO 2025 underscore the trend of moving ICIs into earlier disease settings, including neoadjuvant and adjuvant therapy for improved long-term outcomes, as seen with perioperative pembrolizumab for locally advanced head and neck cancer. Oncology pharmacology treatment guidelines now routinely integrate ICIs into first-line therapies for many advanced cancers. Managing immune-related adverse events (irAEs) is a critical aspect of oncology pharmacology management strategies, as these can affect any organ system and require prompt recognition and corticosteroid-based intervention.

• Adoptive Cell Therapies (ACT): CAR T-cell therapy, initially approved for hematological malignancies (e.g., lymphomas, multiple myeloma), involves genetically engineering a patient's T-cells to express chimeric antigen receptors that target specific cancer antigens. While highly effective, these therapies are associated with unique and severe oncology pharmacology side effects such as cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), demanding specialized expertise and robust supportive care. The year 2025 is witnessing the emergence of next-generation CAR T-cell therapies and the first-ever tumor-infiltrating lymphocyte (TIL) therapy for solid tumors, expanding their reach and impact.
