Summary
Optimizing immune checkpoint inhibitor (ICI) dosing and duration can maintain cancer treatment effectiveness while reducing costs and toxicities, especially in resource-limited settings. These pragmatic strategies improve immunotherapy accessibility and scalability globally.
Area of Science:
- Oncology
- Immunotherapy
- Pharmacokinetics/Pharmacodynamics
Background:
- Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, offering durable responses.
- Widespread use presents challenges in cost, dosing, duration, and immune-related toxicities, particularly in low- and middle-income countries (LMICs).
Purpose of the Study:
- To review exposure optimization strategies for ICIs.
- To explore how these strategies address cost, feasibility, and toxicity challenges.
- To discuss the implications for both LMICs and high-resource settings.
Main Methods:
- Review of pharmacokinetic and pharmacodynamic data on PD-1 receptor occupancy.
- Analysis of clinical evidence from randomized trials and real-world studies.
- Examination of immune-related adverse events (irAEs), focusing on cardiovascular and gastrointestinal toxicities.
Main Results:
- Lower ICI doses and extended intervals can achieve near-maximal PD-1 occupancy, potentially preserving efficacy.
- LMIC-driven adaptations in delivery, toxicity management, and health systems offer practical insights.
- Optimized exposure strategies impact toxicity burden, necessitating careful management of irAEs.
Conclusions:
- Exposure optimization strategies can enhance the affordability and feasibility of cancer immunotherapy.
- These adaptations improve the scalability of ICIs, balancing efficacy, safety, and cost across diverse healthcare settings.
- Insights from LMICs can inform sustainable immunotherapy practices globally.

Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Therapeutic Drug Monitoring: Affecting Factors
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.
Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
