They also present promising solutions to overcome vaccine immunization challenges, particularly in developing nations. The BDCP opportunities, however, are often tempered by intrinsic properties of biologics (e.g. stability, viscosity etc.) and devices (e.g. design control, human factor engineering etc.) which can be further compounded by regulatory complexity across multiple jurisdictions. This comprehensive review examines the current landscape of combination product spanning across the complexities of modality (e.g. proteins, vaccines, oligonucleotide, mRNA/lipid nanoparticle (LNP) and to a limited extent cell & gene therapy) and delivery (parenteral, oral, ocular etc.) through the lens of business drivers, phase-appropriate technical development, regulatory frameworks, and patient-centric design principles. Selected case studies and commercially approved products for each modality are also presented here. Continued investments in new and improved devices such as prefilled syringes, wearable pumps, pen devices, jet devices and autoinjectors for liquid and lyophilized products highlight the recent paradigm shift for integration of delivery devices from self-administration to personalized medicine. Persistent innovation in the field, for example, has enabled device integration beyond chronic conditions such as diabetes and autoimmune diseases and prophylactic vaccination such as flu to cancer immunotherapy. Furthermore, technical, clinical and regulatory successes in achieving novel routes of delivery (e.g. oral biologics, inhaled insulin, inhaled vaccines, intradermal vaccination etc.), smart delivery systems and digital technologies have further advanced the boundaries of BDCP to not only increase market penetration but create new markets.

By integrating a tumor-homing peptide, a cleavable or stimuli-responsive linker, and a potent cytotoxic payload, PDCs offer enhanced tumor selectivity while maintaining structural simplicity and synthetic flexibility. Compared to bulky monoclonal antibody-based systems, PDCs possess significantly smaller molecular size, enabling improved tumor penetration, rapid tissue diffusion, and reduced immunogenicity. Recent advances in peptide engineering have facilitated the development of ligands targeting integrins, G protein-coupled receptors, and other tumor-overexpressed biomarkers, promoting receptor-mediated internalization and intracellular drug release. Linker chemistry plays a pivotal role in therapeutic performance, with enzyme-sensitive, redox-responsive, and pH-cleavable linkers enabling site-specific drug activation within the tumor microenvironment. Despite their promise, PDCs face challenges including rapid renal clearance, proteolytic degradation, and limited circulation half-life. Strategies such as cyclization, PEGylation, and albumin-binding modification have been explored to enhance stability and pharmacokinetics. Furthermore, emerging theranostic PDC platforms incorporate imaging moieties or radiolabels, enabling real-time visualization of tumor targeting, biodistribution, and treatment response. Such dual-functional systems facilitate biomarker-guided patient stratification and image-guided precision therapy. This review comprehensively discusses the structural design principles, delivery barriers, pharmacokinetic considerations, applications, imaging advancements, and current clinical landscape of PDCs, highlighting their advantages over ADCs and outlining future directions for precision oncology.

Chemotherapy-associated MDR is the principal focus of this review, while resistance to targeted therapy and immunotherapy is considered where it directly affects delivery design or patient selection. Bioactive compounds can modulate several resistance pathways, but their translational value is constrained by poor solubility, instability, rapid metabolism and inadequate exposure at resistant lesions. This review critically examines when nanomedicine can make such mechanistic activity pharmacologically and translationally meaningful. We link resistance biology to delivery functions, evaluate bioactive chemosensitiser candidates against human exposure, compare major nanomedicine design strategies, and assess nano-bio interactions, repeat-dose safety, manufacturing and clinical positioning. Across the evidence, three limitations recur. First, concentrations associated with chemosensitisation for curcumin, resveratrol, epigallocatechin gallate and quercetin generally exceed measured human parent-analyte exposure. Second, many resistance claims rely on parental or poorly characterised models, whereas studies combining defined resistance provenance with functional mechanism and exposure confirmation remain uncommon. Third, human studies demonstrate feasibility, tissue exposure or treatment response, but not mechanism-specific reversal of CRC MDR by a bioactive compound or bioactive nanomedicine. Progress therefore depends less on adding new particle classes than on matching a necessary formulation function to a defined resistance or spatial barrier, quantifying active exposure in the relevant compartment, validating mechanism in appropriate models, and integrating repeat-dose safety, scalable manufacturing and biomarker-guided clinical development.</p>","PeriodicalId":7254,"journal":{"name":"Advanced drug delivery reviews","volume":" ","pages":"115957"},"PeriodicalIF":21.0,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148757296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
