Efficacy and safety of the first-line systemic treatments in patients with advanced-stage urothelial carcinoma: a systematic review and network meta-analysis.

Introduction: In recent years, some clinical studies of first-line treatment for advanced-stage urothelial carcinoma (aUC) have reached the main endpoint, showing inconsistent clinical efficacy. We hope to explore the efficacy and safety of first-line treatment for aUC. Methods: The relevant literature from January 2000 to February 2024 was searched, and the R language (version 4.3.1) was used to perform a network meta-analysis based on the JAGS package and GEMTC package under the Bayesian framework. The main indicators included OS, PFS, ORR and adverse events of grade 3 or higher. This study has been registered in PROSPERO (CRD42024525372). Results: A total of 8 RCTs involving 5539 patients and 12 treatments were included. Pembrolizumab plus Enfortumab Vedotin (PEM+EV) was significantly better than other groups in OS, PFS and ORR. In terms of OS, PEM+EV was significantly better than nivolumab plus platinum-based chemotherapy (NIVO+platinumCT) (HR=0.60; 95% CI: 0.45-0.81), PEM+platinumCT (HR=0.55; 95%CI: 0.42-0.72), atezolizumab (ATE) + platinumCT (HR=0.57; 95%CI: 0.43-0.75) and platinumCT (HR=0.47; 95%CI: 0.38-0.58). In terms of PFS, PEM+EV was also significantly better than NIVO+platinumCT (HR=0.62; 95%CI: 0.48-0.82), PEM+platinumCT (HR=0.58; 95%CI: 0.45-0.74), ATE+platinumCT (HR=0.55; 95%CI: 0.43-0.69) and platinumCT (HR=0.45; 95%CI: 0.38-0.54). In terms of ORR, PEM+EV had a significant be nefit compared with other treatment measures, which was 2.63 times that of platinumCT (OR=2.63; 95%CI: 2.00-3.45). The adverse events of grade 3 or higher in immunotherapy (ATE, PEM, durvalumab) was significantly lower than other treatment measures. Conclusions: PEM+EV can significantly prolong OS and PFS compared with other treatments, and has a higher ORR. The adverse events of grade 3 or higher of ATE was the lowest.

Advancing Ovarian Cancer Therapeutics: The Role of Targeted Drug Delivery Systems.

Ovarian cancer (OC) is the most lethal reproductive system cancer and a leading cause of cancer-related death. The high mortality rate and poor prognosis of OC are primarily due to its tendency for extensive abdominal metastasis, late diagnosis in advanced stages, an immunosuppressive tumor microenvironment, significant adverse reactions to first-line chemotherapy, and the development of chemoresistance. Current adjuvant chemotherapies face challenges such as poor targeting, low efficacy, and significant side effects. Targeted drug delivery systems (TDDSs) are designed to deliver drugs precisely to the tumor site to enhance efficacy and minimize side effects. This review highlights recent advancements in the use of TDDSs for OC therapies, including drug conjugate delivery systems, nanoparticle drug delivery systems, and hydrogel drug delivery systems. The focus is on employing TDDS to conduct direct, effective, and safer interventions in OC through methods such as targeted tumor recognition and controlled drug release, either independently or in combination. This review also discusses the prospects and challenges for further development of TDDSs. Undoubtedly, the use of TDDSs shows promise in the battle against OCs.

Recent Advances in the Linkers of Drug Conjugates.

Drug conjugates have emerged as a pivotal research focus in the field of targeted cancer therapy. They represent a widely explored prodrug strategy that significantly enhances the therapeutic index of drugs while minimizing side effects. The stability and selective cleavage of the linker within drug conjugates are critical for the therapeutic efficacy and targeted treatment achieved by these conjugates. In this review, we have categorized the linkers based on their cleavage mode and summarized the chemical properties, advantages, and limitations of various types of cleavable linkers. Particularly, examples have been provided to illustrate their specific potential for development.

Drug combinations of camptothecin derivatives promote the antitumor properties.

Camptothecin (CPT) derivatives are widely used as small molecule chemotherapeutic agents and have demonstrated efficacy in the treatment of diverse solid tumors. A variety of derivatives have been developed to resolve the drawbacks of poor water solubility, high toxicity and rapid hydrolysis in vivo. However, the obstacles, such as acquired resistance and toxicity, still exist. The utilization of rational drug combinations has the potential to enhance the efficacy and mitigate the toxicity of CPT derivatives. This paper provides an overview of CPT derivatives in combination with other drugs, with a particular focus on cell cycle inhibitors, DNA synthesis inhibitors, anti-metastatic drugs and immunotherapy agents. Concurrently, the mechanisms of antitumor activity of combinations of different classes of drugs and CPT derivatives are elucidated. While the various combination strategies have yielded more favorable therapeutic outcomes, the efficacy and toxicity of the drug combinations are influenced by the inherent properties of the drugs involved. Moreover, a summary of the drug conjugates of CPT derivatives was provided, accompanied by an analysis of the structural activity relationship (SAR). This paves the way for the subsequent developments in drug combinations and delivery modes.

Breast cancer drugs: FDA approval, development time, efficacy, clinical benefits, innovation, trials, endpoints, quality of life, value, and price.

OBJECTIVE: This study analyzes the development, benefits, trial evidence, and price of new breast cancer drugs with US Food and Drug Administration (FDA) approval. METHODS: We identified 26 drugs with 42 FDA-approved indications for early and metastatic breast cancer (2000-2023). Data were collected from FDA labels, clinicaltrials.gov, and Medicare and Medicaid. Overall survival (OS) and progression-free survival (PFS) hazard ratios (HRs) and tumor response's relative risk (RR) alongside objective response rate (ORR) were meta-analyzed. RESULTS: The median development time for breast cancer drugs was 7.8 years (95% CI 6.2-10.8). 26% of treatments were considered innovative ("first-in-indication") with 88% acting via a targeted mechanism. 64% were small molecules, 19% antibodies, and 18% antibody-drug conjugates. 38% were approved for HR + and 31% for HER2 + breast cancer. 6 indications were for early and 36 for metastatic breast cancer. Indications utilized FDA's special programs: orphan (2%), fast track (24%), accelerated approval (19%), priority review (74%), breakthrough therapy (44%). Approval was predominantly supported by phase 3 trials (88%) of randomized controlled design (66%), enrolling a median of 585 patients (IQR 417-752) at 181 centers (IQR 142-223) across 19 countries (IQR 17-20). New drugs' HR were 0.78 for OS (95% CI 0.74-0.82) and 0.59 for PFS (95% CI 0.54-0.64) with a RR for tumor response of 1.61 (95% CI 1.46-1.76). Median improvements of OS were 2.8 months (IQR 1.8-5.8) and PFS were 4.4 months (IQR 2.2-7.1). In single-arm trials, the average ORR was 31% (95% CI 10-53). In meta-regressions, the correlation between OS/PFS was 0.34 (p = 0.031) and OS/response was 0.01 (p = 0.435). 60% of treatments had a 'high-value' ESMO-MCBS score with 14% demonstrating improvements in quality of life. The median price was $16,013 per month (95% CI 13,097-17,617). There was no association between prices and patient benefit. The median value per life year gained was $62,419 (IQR 25,840-86,062). CONCLUSIONS: Over the past two decades, the development of innovative and effective drugs transformed the treatment landscape for breast cancer patients. Yet, investigators and regulators must safeguard that highly-priced new drugs demonstrate improvements in patient-centered clinical endpoints: overall survival and quality of life.

Unmet needs in cervical cancer - can biological therapies plug the gap?

INTRODUCTION: Cervical cancer remains one of the most common gynecologic malignancies worldwide. A disproportionate burden of cases occurs in developing countries due to inadequate screening and treatment. Even among patients adequately treated, in the presence of locally advanced or recurrent disease, outcomes tend to be poor. The introduction of biologic therapy into treatment has increased overall survival; however, a considerable opportunity still exists to improve current standards in treatment. Biologics have shown antitumor activity in multiple tumor types and are actively being pursued for the management of cervical cancer. AREAS COVERED: In this article, we will discuss the historical evolution of biologic therapy in cervical cancer including use of angiogenesis inhibitors, immune checkpoint inhibitors, antibody-drug conjugates, and vaccines. We will review how these therapies have been integrated into current treatment recommendations and discuss ongoing investigations intended to improve clinical outcomes. We also postulate on persistent gaps in care. EXPERT OPINION: Biologic therapies have had a tremendous impact on our current approach to managing cervical cancer. We anticipate that significant more research and development will be committed to the continued investigation of biologics in cervical cancer in an effort to improve a historically difficult to treat malignancy.

Molecular mechanisms of HER2-targeted therapy and strategies to overcome the drug resistance in colorectal cancer.

HER2 amplification is one of the mechanisms that induce drug resistance to anti-EGFR therapy in colorectal cancer. In recent years, data from several randomized clinical trials show that anti-HER2 therapies improved the prognosis of patients with HER2-positive colorectal cancer. These results indicate that HER2 is a promising therapeutic target in advanced colorectal cancer. Despite the anti-HER2 therapies including monoclonal antibodies, tyrosine kinase inhibitors, and antibody-drug conjugates improving the outcomes, less than 30 % of the patients achieve objective response and eventually have drug resistance. It is necessary to explore the primary and secondary mechanisms for the resistance to anti-HER2 therapies, which will pave the way to overcome the drug resistance. Several studies have reported the potential mechanisms for the resistance to anti-HER2 therapies. In this review, we present a comprehensive overview of the recent advances in clinical research, mechanisms of treatment resistance, and strategies for reversing resistance in HER2-positive colorectal cancer patients.

Clinical strategies with antibody-drug conjugates as potential modifications for virotherapy.

The ability to selectively target cancer cells makes antibody-drug conjugates (ADCs) promising therapeutic options. They have been tested in clinical trials as a vehicle for tumor-specific delivery of cytotoxic payloads for a range of cancers. However, systemic administration of oncolytic virotherapy is challenging, because only a small portion of injected viruses reach the target. Despite the approval of higher viral doses, most viruses still end up in the liver, potentially causing toxicity in that organ. Integrating ADCs with virotherapy in the form of antibody-virus conjugates or virus-drug conjugates can potentially overcome these challenges and improve therapeutic outcomes.

Future AI Will Most Likely Predict Antibody-Drug Conjugate Response in Oncology: A Review and Expert Opinion.

The medical research field has been tremendously galvanized to improve the prediction of therapy efficacy by the revolution in artificial intelligence (AI). An earnest desire to find better ways to predict the effectiveness of therapy with the use of AI has propelled the evolution of new models in which it can become more applicable in clinical settings such as breast cancer detection. However, in some instances, the U.S. Food and Drug Administration was obliged to back some previously approved inaccurate models for AI-based prognostic models because they eventually produce inaccurate prognoses for specific patients who might be at risk of heart failure. In light of instances in which the medical research community has often evolved some unrealistic expectations regarding the advances in AI and its potential use for medical purposes, implementing standard procedures for AI-based cancer models is critical. Specifically, models would have to meet some general parameters for standardization, transparency of their logistic modules, and avoidance of algorithm biases. In this review, we summarize the current knowledge about AI-based prognostic methods and describe how they may be used in the future for predicting antibody-drug conjugate efficacy in cancer patients. We also summarize the findings of recent late-phase clinical trials using these conjugates for cancer therapy.

Analysis of HER2-Low Breast Cancer in Aotearoa New Zealand: A Nationwide Retrospective Cohort Study.

OBJECTIVES: To perform the first national analysis of demographic and clinicopathological features associated with the HER2 positive, HER2-low, and HER2-zero invasive breast cancers in New Zealand. The study will reveal the proportion of women who may benefit from new HER2-targeted antibody drug conjugate (ADC) therapies. METHODS: Utilising data from Te Rehita Mate Utaetae (Breast Cancer Foundation NZ National Register), the study analysed data from women diagnosed with invasive breast cancer over a 21-year period. The HER2 status of tumours was classified into three categories-HER2-zero, HER2-low, HER2-positive. RESULTS: From 2009-2021, 94% of women underwent HER2 testing, with 14% diagnosed with HER2-positive breast cancer. For advanced-stage disease, 38% of those formerly classified as HER2-negative were reclassified as HER2-low. Including HER2-positive breast cancers, this indicates that 60% of women with advanced breast cancer may potentially benefit from the new HER2-directed ADCs (approximately 120 women per year). CONCLUSIONS: The findings suggest a significant proportion of women with invasive breast cancer in New Zealand could benefit from new HER2-targeted treatments. There is a need to standardise HER2 testing to enhance personalised treatment and improve outcomes.

Synergizing Immunotherapy and Antibody-Drug Conjugates: New Horizons in Breast Cancer Therapy.

The advent of immunotherapy and antibody-drug conjugates (ADCs) have revolutionized breast cancer treatment, offering new hope to patients. However, challenges, such as resistance and limited efficacy in certain cases, remain. Recently, the combination of these therapies has emerged as a promising approach to address these challenges. ADCs play a crucial role by delivering cytotoxic agents directly to breast cancer cells, minimizing damage to healthy tissue and enhancing the tumor-killing effect. Concurrently, immunotherapies harness the body's immune system to recognize and eliminate cancer cells. This integration offers potential to overcome resistance mechanisms and significantly improve therapeutic outcomes. This review explores the rationale behind combining immunotherapies with ADCs, recent advances in this field, and the potential implications for breast cancer treatment.

Synergistic Chemo-Immunotherapy: Recombinant Fusion Protein-Based Surface Modification of NK Cell for Targeted Cancer Treatment.

While traditional combination anticancer treatments have shown promising results, there remains significant interest in developing innovative methods to enhance and integrate chemotherapy and immunotherapy. This study introduces a recombinant fusion protein-based cell surface modification system that synergistically combines chemotherapy and immunotherapy into a single-targeted chemo-immunotherapy approach. A cell surface-modified protein composed of an antibody-specific binding domain and a cell-penetrating domain rapidly converts immune cells into chemo-immuno therapeutics by binding to antibodies on the surface of immune cells. Utilizing a non-invasive, non-toxic approach free of chemical modifications and binding, our system homogeneously transforms immune cells by transiently introducing targeted cytotoxic drugs into them. The surface-engineered immune cells loaded with antibody-drug conjugates (ADCs) significantly inhibit the growth of target tumors and enhance the targeted elimination of cancer cells. Therefore, NK cells modified by the cell surface-modified protein to incorporate ADCs could be expected to achieve the combined effects of targeted cancer cell recognition, chemotherapy, and immunotherapy, thereby enhancing their therapeutic efficacy against cancer. This strategy allows for the efficient and rapid preparation of advanced chemo-immuno therapeutics to treat various types of cancer and provides significant potential to improve the efficacy of cancer treatment.

Real-world treatment patterns and outcomes in patients with HR+/HER2- metastatic breast cancer treated with chemotherapy in the United States.

BACKGROUND: Until recently, treatment options for patients with hormone receptor-positive/human epidermal growth factor 2-negative (HR+/HER2-) metastatic breast cancer (mBC) and resistance to endocrine therapy were limited to chemotherapy. This real-world study describes treatment patterns and outcomes in patients treated with chemotherapy in the United States before approval of antibody-drug conjugates. PATIENTS AND METHODS: This retrospective, observational study included adults with HR+/HER2- mBC from the ConcertAI Patient360™ Breast Cancer dataset who initiated their first chemotherapy in the metastatic setting between January 2011 and June 2021. Treatment patterns were described; real-world overall survival, time to next treatment or death, and real-world progression-free survival were evaluated for all eligible patients and patients treated with subsequent chemotherapy. Index dates were the start date of each chemotherapy treatment. RESULTS: Among 1545 eligible patients, 76% were white, 12% had Eastern Cooperative Oncology Group performance status ≥2, 38% had de novo mBC, and median age was 61 years (range, 52-69 years). Within the index period, capecitabine was used the most as the first chemotherapy agent and decreased in later treatments, while the use of eribulin increased between first and fourth chemotherapies. Median (95% confidence interval) real-world overall survival was 23.3 months (21.3-25.4 months) from start of first chemotherapy, time to next treatment or death was 6.5 months (5.9-7.1 months), and real-world progression-free survival was 6.9 months (6.4-7.6 months); median times from second, third, and fourth chemotherapies decreased with each additional chemotherapy treatment. CONCLUSIONS: This real-world study demonstrates that for patients with HR+/HER2- mBC, chemotherapy provides relatively limited survival benefit which decreases with each additional chemotherapy line, and highlights the need for improved treatment options.

Dual immunostimulatory CD73 antibody-polymeric cytotoxic drug complex for triple negative breast cancer therapy.

Treatment of triple-negative breast cancer (TNBC) poses significant challenges due to its propensity for metastasis. A key impediment lies in the suppressive immune microenvironment, which fosters tumor progression. This study introduces an approach employing a dual immune-stimulatory CD73 antibody-polymeric cytotoxic drug complex (αCD73-PLG-MMAE). This complex is designed for targeted eradication of TNBC while modulating tumor immunity through mechanisms such as immunogenic cell death (ICD) and interference with the adenosine signaling pathway. By enhancing antitumor immune responses, this strategy offers a highly effective means of treating TNBC and mitigating metastasis. The complex is synthesized by combining αCD73 with poly(L-glutamic acid) (PLG) grafted Fc binding peptides (Fc-III-4C) and Val-Cit-PAB-monomethyl auristatin E (MMAE), exploiting the affinity between αCD73 and Fc-III-4C. αCD73 selectively targets CD73 molecules on both tumor and immune suppressive cells, thereby inhibiting the adenosine pathway. Meanwhile, Val-Cit-PAB-MMAE, activated by cathepsin B, triggers selective release of MMAE, inducing ICD in tumor cells. In a 4T1 tumor model, αCD73-PLG-MMAE significantly enhances drug accumulation in tumors by 4.13-fold compared to IgG-PLG-MMAE, leading to suppression of tumor growth and metastasis. Furthermore, it synergistically augments the antitumor effects of αPD-1, resulting in a tumor inhibition rate of 92% as compared to 21% with αPD-1 alone. This study thus presents a pioneering therapeutic strategy for TNBC, emphasizing the potential of targeted immunomodulation in cancer treatment. STATEMENT OF SIGNIFICANCE: Antibody-drug conjugate (ADC) therapy holds promise for treating triple-negative breast cancer (TNBC). However, the current ADC, sacituzumab govitecan, fails to overcome the crucial role of adenosine in the suppressive immune microenvironment characteristic of this "cold tumor". Here, we present a dual immune-stimulatory complex, αCD73-PLG-MMAE, which targets TNBC specifically and modulates tumor immunity through mechanisms such as immunogenic cell death (ICD) and interference with the adenosine signaling pathway. Thus, it kills tumor cells with cytotoxic drugs, comprehensively regulates immunosuppression, and restores a durable immune response. This study proposes an antibody-polymeric drug complex with immunomodulatory and immunoagonist roles, offering new insights into TNBC treatment.

Microtubule dynamics in cancer metastasis: Harnessing the underappreciated potential for therapeutic interventions.

Microtubules, dynamic cytoskeletal structures crucial for cellular processes, have surfaced as promising targets for cancer therapy owing to their pivotal role in cancer progression and metastasis. This review comprehensively explores the multifaceted landscape of microtubule-targeting drugs and their potential to inihibit cancer metastasis. Although the role of Actin cytoskeleton is well known in controlling metastasis, only recently Microtubules are emerging as a potential controller of metastasis. We delve into the processes at the core of antimetastatic impacts of microtubule-targeting agents, both through direct modulation of microtubules and via alternative pathways. Drawing from in vitro and in vivo studies, we analyze the cytotoxic and antimetastatic doses of various compounds, shedding light on their therapeutic potential. Furthermore, we discuss the emerging class of microtubule targeting drugs, and their role in metastasis inhibition, such as microtubules acetylation inhibitory drugs, particularly histone deacetylase inihibitors and antibody-drug conjugates. Histone deacetylase (HDAC) strengthens the microtubule cytoskeleton through acetylation. Recently, HDAC inhibitors have been discovered to have antimetastatic properties. Here, the role of HDAC inhibitors in stopping metastasis is discussed with respect to microtubule cytoskeleton. Surprisingly, novel antibody conjugates of microtubule-targeting agents, which are in clinical trials, were found to be antimetastatic. This review discusses these antibody conjugates in detail. Additionally, we elucidate the intricate crosstalk between microtubules and other cytoskeletal proteins, unveiling novel therapeutic strategies for metastasis suppression. By providing a wide-ranging overview of the complex interplay between microtubules and cancer metastasis, this review contributes to the comprehension of cancer's biological mechanisms and the development of innovative therapeutic interventions to mitigate metastatic progression.

Synthesis and evaluation of homocamptothecin antibody-drug conjugates for cancer treatment.

As an emerging tumor therapeutic strategy, antibody-drug conjugates (ADCs) overcome the high toxicity of traditional small molecule chemotherapy and improve the targeting of treatment. In this study, we successfully constructed a novel ADC, Tras-16b, for the first time using homocamptothecin 16b as the payload. Tras-16b, at a dose of 3 mg/kg, exhibited comparable anti-tumor activity to Enhertu and demonstrated an enhanced safety profile in the NCI-N87 xenograft model. Notably, this is the first ADC developed based on homocamptothecin, marking a significant advancement with promising prospects for the structural modification of camptothecin ADCs.

Antibody drug conjugates in recurrent or metastatic cervical cancer: a focus on tisotumab vedotin state of art.

Cervical cancer (CC) is still characterized by a poor prognosis despite the progress made in its treatment in recent years. Although immunotherapy has improved outcomes for advanced/recurrent disease, there is a significant gap in addressing patients' needs when they progress after platinum and immunotherapy treatments. In this setting, traditional chemotherapy showed limited effectiveness. In this context, antibody-drug conjugates (ADCs) emerged as a promising tool within targeted cancer therapies. Tisotumab vedotin (TV), an ADC targeting tissue factor, represents the first ADC approved by the US Food and Drug Administration for the treatment of recurrent or metastatic CC with disease progression on or after chemotherapy. In phase I-III published trials, TV has already demonstrated an advantage in terms of objective response rate (17.8%-54.4%) and progression-free survival (3.1-6.9 months) in patients who progressed to the first-line standard therapy. Data concerning the addition of TV to platinum/pembrolizumab first-line chemotherapy are still under analysis and strongly expected. However, several questions are still unresolved: (1) the identification of the most suitable timing for ADCs administration in the treatment sequence of advanced/recurrent CC; (2) the evaluation of combination therapies as a tool to minimize the emergence of resistant clones and to enhance overall effectiveness; and (3) the assessment of tolerability and correct management of special toxicities (e.g. ocular and neurological adverse events). In the near future, an improvement in patient selection via biomarker-driven strategies should be crucial for optimizing both treatment benefits and maintaining an acceptable toxicity profile.

Blood-brain barrier and blood-brain tumor barrier penetrating peptide-drug conjugate as targeted therapy for the treatment of lung cancer brain metastasis.

Lung cancer is the leading cause of cancer deaths worldwide. Brain metastasis of lung cancer, which counts for nearly 50% of late-stage lung cancer patients, is a sign of a really poor prognosis. However, the presence of blood-brain barrier (BBB) and blood-brain tumor barrier (BBTB) limits the penetration of drugs from the blood into the brain and thus restricts their accumulation in brain tumors. Systematic delivery of drugs into brain and brain tumor lesion using BBB and BBTB penetrating vehicles represents a promising strategy to overcome the BBB and BBTB limitations. Hence, we validated one of our previously identified BBB/BBTB penetrating peptide and its drug conjugate form for the treatment of lung cancer brain metastasis. With in vitro experiment, we first validated that the receptor LRP1, which mediated the peptide penetration of the BBB, was expressed on lung cancer cells and thus can be targeted by the peptide to overcome BBTB. With this delivery peptide, we constructed peptide-paclitaxel conjugate (the PDC) and in vitro validation showed that the PDC can across the BBB and efficiently kill lung cancer cells. We therefore constructed mouse lung cancer brain metastasis xenograft. In vivo anti-tumor validations showed that the PDC efficiently inhibited the proliferation of the brain resident lung cancer cells and significantly expanded the survival of the mouse xenograft, with no visible damages to the organs. Overall, our study provided potential therapeutic drugs for the treatment of lung cancer brain metastasis that may be clinically effective in the near future.

Exploiting the bile acid binding protein as transporter of a Cholic Acid/Mirin bioconjugate for potential applications in liver cancer therapy.

Bioconjugation is one of the most promising strategies to improve drug delivery, especially in cancer therapy. Biomolecules such as bile acids (BAs) have been intensively explored as carriers, due to their peculiar physicochemical properties and biocompatibility. BAs trafficking is regulated by intracellular lipid-binding proteins and their transport in the liver can be studied using chicken liver Bile Acid-Binding Proteins (cL-BABPs) as a reference model. Therefore, we conceived the idea of developing a BA-conjugate with Mirin, an exonuclease inhibitor of Mre11 endowed with different anticancer activities, to direct its transport to the liver. Following computational analysis of various BAs in complex with cL-BABP, we identified cholic acid (CA) as the most promising candidate as carrier, leading to the synthesis of a novel bioconjugate named CA-M11. As predicted by computational data and confirmed by X-ray crystallographic studies, CA-M11 was able to accommodate into the binding pocket of BABP. Hence, it can enter BAs trafficking in the hepatic compartment and here release Mirin. The effect of CA-M11, evaluated in combination with varying concentrations of Doxorubicin on HepG2 cell line, demonstrated a significant increase in cell mortality compared to the use of the cytotoxic drug or Mirin alone, thus highlighting chemo-sensitizing properties. The promising results regarding plasma stability for CA-M11 validate its potential as a valuable agent or adjuvant for hepatic cancer therapy.
