• Potential Activity of Non-Platinum Metal-Based Organic Complexes Against Different Cancer Cell Types. D. Tsvetkova, S. Ivanova, D. Obreshkova. 2026;19(6). Review PubMed · Publisher · Free full text

  Abstract

  The disadvantages of Cisplatin in anticancer treatment are connected to its poor selectivity, resistance developed of cancers to the drug, and its toxicity against normal organs. An important strategy in anticancer treatment is the synthesis and clinical investigation of non-platinum metal complexes with superior anticancer activity and improved selectivity compared to Cisplatin, combined with lower toxicity, fewer side effects and decreased resistance of cancer to the drug. In the current study, we aim to summarize the potential of important non-platinum metal-based organic compounds as therapeutic agents against different cancer cell types. The review covers the general principles of chemotherapy. A literature analysis shows that organic complexes of the metalloids arsenic (As), boron (B), antimony (Sb), and selenium (Se), and of metals, such as Ag, Au, Co, Cu, Fe, Mn, Mo, Ni, Zn, Ce, Ga, Gd, Ir, Os, Pd, Re, Rh, Ru, Ti, and V, have been investigated for potential applications in cancer therapy. This is due to their antiproliferative effects against different cancer types: lung [Cd(II), Co(II), Cu(II), Ni(II), Mn(II), Ru(II), Zn(II)]; breast [Ag(I), Cu(I), Cu(II), Ir(III), Ni(II), Mn(II),. Rh(III), Ru(II)]; gastric [Cu(II), Cu(II)-La(III)]; colon [Ag(I), Cu(II), Ir(III), Pd(II), Rh(III), Ru(II), vanadium(V)]; colorectal [Ag(I), Co(II), Cu(II), Zn(II)]; liver [Ag(I), Co(II), Cu(II), Gd(III), vanadium(V)]; pancreatic [vanadium(IV)]; bladder [Ag(I), Cu(II), Ru(II)]; cervical [Ag(I), Au(I), Cu(I), Cu(II), Fe(II), Ir(III), Rh(III), Ru(II)]; testicular [vanadium(IV)]; prostate [Cu(II), Pd(II), Zn(II)]; leukemia [Ag(I), Co(II), Cu(II), Pd(II), Zn(II)]; sarcoma [Co(II), Ni(II), Zn(II)]; mesothelioma [Cu(II)]; neuroblastoma [Cu(II)]; glioma [Cu(II)]; and melanoma [Au(I), Cu(II), Pd(II), Ru(II)]. The main goals for increasing anticancer metal-based complexes include increasing anticancer activity and selectivity, reducing toxicity, and avoiding cancer cell resistance. Compared to Cisplatin, organocomplexes of copper, ferrocene, and ruthenium are more active. Ruthenium and copper complexes, in particular, are also more selective. Notably, ruthenium and ferrocene derivatives are less toxic than Cisplatin. Lastly, cancers appear to exhibit less resistance against copper, gold, ruthenium, palladium, and ferrocene complexes.

• Radioimmunotherapy for Malignant Mesothelioma Targeting C-ERC/Mesothelin. H. Hanaoka, A. Yamaguchi, M. Maeda, et al. 2026;19(3). PubMed · Publisher · Free full text

  Abstract

  Background/Objectives: Malignant mesothelioma has a poor prognosis and limited therapeutic options. C-ERC/mesothelin is highly expressed in mesotheliomas and is a potential target for radioimmunotherapy (RIT). This study evaluated the radiolabeled anti-C-ERC/mesothelin antibody mAb 22A31 as a therapeutic agent. Methods: C-ERC/mesothelin expression in mesothelioma cell lines was assessed by Western blotting, and the specific binding of 125I-labeled mAb 22A31 was examined. Biodistribution of 111In-labeled mAb 22A31 was evaluated in a mesothelioma cell line, MSTO-211H tumor-bearing mice. The therapeutic efficacy of 90Y-labeled mAb 22A31 was evaluated in subcutaneous and pleural dissemination models. Results: mAb 22A31 showed specific binding considering the level of C-ERC/mesothelin expression in each mesothelioma cell line. 111In-mAb 22A31 accumulated in tumors with minimal uptake in normal tissues. 90Y-mAb 22A31 significantly delayed the growth of subcutaneous tumors and improved survival in a pleural dissemination model. Conclusions: Radiolabeled mAb 22A31 specifically targeted C-ERC/mesothelin and demonstrated therapeutic efficacy in a mesothelioma xerograph model. Therefore, 90Y-mAb 22A31 is a promising RIT agent and supports the further development of C-ERC/mesothelin-targeted therapy for mesothelioma.

• First-in-Human Phase I Clinical Trial of SLC-391, a Novel and Selective AXL Inhibitor, in Patients with Advanced Solid Tumours. Z. Zhang, D. Morrison, L. Lu, et al. 2025;18(12). PubMed · Publisher · Free full text

  Abstract

  Background/Objectives: AXL, a receptor tyrosine kinase of the TAM family, has emerged as a key target in cancer therapy due to its role in tumour growth, metastasis, immune evasion, and therapy resistance. SLC-391, a novel, orally bioavailable and selective AXL inhibitor, has demonstrated potent anti-tumour effects in preclinical studies. This first-in-human, open-label, multi-centre Phase I clinical trial (NCT03990454) was conducted to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of SLC-391 in patients with advanced solid tumours. Methods: Using a 3 + 3 design, SLC-391 was administered orally, either once daily (from 25 mg up to 175 mg QD) or twice daily (from 75 mg to 200 mg BID) in 21-day cycles. Results: Following single and repeated dosing, SLC-391 was generally well tolerated by subjects. The maximum tolerated dose (MTD) was not reached in this study. A total of 34/35 subjects experienced at least one TEAE. Three (8.6%) subjects experienced Grade 3 TRAEs that were considered related to SLC-391. Eight SAEs were reported in five (14.3%) subjects (seven Grade 3 SAEs and one Grade 2 SAE), in 150 mg QD (3/6, 50%), 175 mg QD (1/2, 50%), and 110 mg BID (1/3, 33.3%) cohorts. Four SAEs in three (8.6%) subjects led to dose interruption, drug withdrawal, or study discontinuation. Three DLTs were reported in two subjects: one subject experienced Grade 3 hematochezia (SUSAR/DLT) at 175 mg QD, and another subject experienced Grade 3 thrombocytopenia associated with Grade 1 hematuria at 200 mg BID. The median Tmax was 2.0 h. Plasma concentrations following multiple doses generally increased with higher doses and appeared to reach steady state by Day 21 and were generally dose-proportional. Twelve (12) out of 35 subjects with solid tumours achieved stable disease according to RECIST or mRECIST (mesothelioma), with durations of stable disease lasting up to 318 days on SLC-391 monotherapy. The clinical benefit rate was 34.3%. Conclusions: This first study of SLC-391 in adult subjects with advanced solid tumours demonstrated that a total daily dose of 300 mg (150 mg BID) of SLC-391 monotherapy was generally well tolerated, with no DLTs or SAEs observed at this dose. The drug's promising safety profile, along with stable disease reported for several subjects with advanced solid tumours, provides a strong rationale for the phase 1b/2a clinical investigation of SLC-391 in combination with pembrolizumab in subjects with advanced or metastatic non-small cell lung cancer (NSCLC) (NCT05860296).

• 2-Hydroxyoleic Acid as a Self-Assembly Inducer for Anti-Cancer Drug-Centered Nanoparticles. A.I. Antoniou, G. Nordio, M.L. Di Paolo, et al. 2023;16(5). PubMed · Publisher · Free full text

  Abstract

  A potent nontoxic antitumor drug, 2-hydroxyoleic acid (6, 2OHOA) used for membrane lipid therapy, was selected as a self-assembly inducer due to its ability to form nanoparticles (NPs) in water. For this purpose, it was conjugated with a series of anticancer drugs through a disulfide-containing linker to enhance cell penetration and to secure drug release inside the cell. The antiproliferative evaluation of the synthesized NP formulations against three human tumor cell lines (biphasic mesothelioma MSTO-211H, colorectal adenocarcinoma HT-29, and glioblastoma LN-229) showed that nanoassemblies 16-22a,bNPs exhibit antiproliferative activity at micromolar and submicromolar concentrations. Furthermore, the ability of the disulfide-containing linker to promote cellular effects was confirmed for most nanoformulations. Finally, 17bNP induced intracellular ROS increase in glioblastoma LN-229 cells similarly to free drug 8, and such elevated production was decreased by pretreatment with the antioxidant N-acetylcysteine. Also, nanoformulations 18bNP and 21bNP confirmed the mechanism of action of the free drugs.

• Comparative Assessment and High-Throughput Drug-Combination Profiling of TEAD-Palmitoylation Inhibitors in Hippo Pathway Deficient Mesothelioma. L. Evsen, P.J. Morris, C.J. Thomas, et al. 2023;16(12). PubMed · Publisher · Free full text

  Abstract

  The hippo signaling pathway is a central tumor suppressor cascade frequently inactivated in selected human cancers, leading to the aberrant activation of TEAD transcription factors. Whereas several TEAD auto-palmitoylation inhibitors are currently in development, a comprehensive assessment of this novel drug-modality is missing. Here, we report a comparative analysis among six TEADi(s) using cell-based and biochemical assays in Hippo pathway deficient mesothelioma. Our analysis revealed varying potency and selectivity across TEADi, also highlighting their limited efficacy. To overcome this limitation, we performed an unbiased, quantitative high-throughput drug screening by combining the TEADi VT-103 with a library of approximately 3000 oncology-focused drugs. By exploiting this library's mechanistic redundancy, we identified several drug-classes robustly synergized with TEADi. These included glucocorticoid-receptor (GR) agonists, Mek1/2 inhibitors, mTOR inhibitors, and PI3K inhibitors, among others. Altogether, we report a coherent single-agent dataset informing on potency and selectivity of TEAD-palmitoylation inhibitors as single-agents. We also describe a rational pipeline enabling the systematic identification of TEAD druggable co-dependencies. This data should support the pre-clinical development of drug combination strategies for the treatment of Hippo-deficient mesothelioma, and more broadly, for other cancers dependent on the oncogenic activity of YAP/TEAD.

• Cyclin-Dependent Kinase and Antioxidant Gene Expression in Cancers with Poor Therapeutic Response. G.S. Scaria, B.T. Kren, M.A. Klein. 2020;13(2). PubMed · Publisher · Free full text

  Abstract

  Pancreatic cancer, hepatocellular carcinoma (HCC), and mesothelioma are treatment-refractory cancers, and patients afflicted with these cancers generally have a very poor prognosis. The genomics of these tumors were analyzed as part of The Cancer Genome Atlas (TCGA) project. However, these analyses are an overview and may miss pathway interactions that could be exploited for therapeutic targeting. In this study, the TCGA Pan-Cancer datasets were queried via cBioPortal for correlations among mRNA expression of key genes in the cell cycle and mitochondrial (mt) antioxidant defense pathways. Here we describe these correlations. The results support further evaluation to develop combination treatment strategies that target these two critical pathways in pancreatic cancer, hepatocellular carcinoma, and mesothelioma.

• Targeting and Efficacy of Novel mAb806-Antibody-Drug Conjugates in Malignant Mesothelioma. P.L. Chia, S. Parakh, M.S. Tsao, et al. 2020;13(10). PubMed · Publisher · Free full text

  Abstract

  Epidermal growth factor receptor (EGFR) is highly overexpressed in malignant mesothelioma (MM). MAb806 is a novel anti-EGFR antibody that selectively targets a tumor-selective epitope. MAb806-derived antibody drug conjugates (ADCs), ABT-414, ABBV-221 and ABBV-322, may represent a novel therapeutic strategy in MM. EGFR and mAb806 epitope expressions in mesothelioma cell lines were evaluated using an array of binding assays, and the in vitro cell effects of ABT-414 and ABBV-322 were determined. In vivo therapy studies were conducted in mesothelioma xenograft and patient-derived xenograft (PDX) tumor models. We also performed biodistribution and imaging studies to allow the quantitative targeting of MM by mAb806 using a 89Zr-labeled immunoconjugate-ch806. A high EGFR expression was present in all mesothelioma cell lines evaluated and mAb806 binding present in all cell lines, except NCIH-2452. ABT-414 and ABBV-322 resulted in significant tumor growth inhibition in MM models with high EGFR and mAb806 epitope expressions. In contrast, in an EGFR-expressing PDX model that was negative for the mAb806 epitope, no growth inhibition was observed. We demonstrated the specific targeting of the mAb806 epitope expressing MM tumors using 89Zr-based PET imaging. Our data suggest that targeting EGFR in MM using specific ADCs is a valid therapeutic strategy and supports further investigation of the mAb806 epitope expression as a predictive biomarker.

• TLD1433-Mediated Photodynamic Therapy with an Optical Surface Applicator in the Treatment of Lung Cancer Cells In Vitro. S. Chamberlain, H.D. Cole, J. Roque, et al. 2020;13(7). PubMed · Publisher · Free full text

  Abstract

  Intra-operative photodynamic therapy (IO-PDT) in combination with surgery for the treatment of non-small cell lung cancer and malignant pleural mesothelioma has shown promise in improving overall survival in patients. Here, we developed a PDT platform consisting of a ruthenium-based photosensitizer (TLD1433) activated by an optical surface applicator (OSA) for the management of residual disease. Human lung adenocarcinoma (A549) cell viability was assessed after treatment with TLD1433-mediated PDT illuminated with either 532- or 630-nm light with a micro-lens laser fiber. This TLD1433-mediated PDT induced an EC50 of 1.98 μM (J/cm2) and 4807 μM (J/cm2) for green and red light, respectively. Cells were then treated with 10 µM TLD1433 in a 96-well plate with the OSA using two 2-cm radial diffusers, each transmitted 532 nm light at 50 mW/cm for 278 s. Monte Carlo simulations of the surface light propagation from the OSA computed light fluence (J/cm2) and irradiance (mW/cm2) distribution. In regions where 100% loss in cell viability was measured, the simulations suggest that >20 J/cm2 of 532 nm was delivered. Our studies indicate that TLD1433-mediated PDT with the OSA and light simulations have the potential to become a platform for treatment planning for IO-PDT.
