Peptide-based radiopharmaceuticals targeting integrin α5β1 show promise for precise tumor diagnosis and treatment. However, current peptide-based radioligands that target α5β1 demonstrate inadequate in vivo performance owing to limited tumor retention. The use of PEGylation to enhance the tumor retention of radiopharmaceuticals by prolonging blood circulation time poses a risk of increased blood toxicity. Therefore, a PEGylation strategy that boosts tumor retention while minimizing blood circulation time is urgently needed. Here, we developed a PEGylation-enabled peptide multidisplay platform (PEGibody) for PR_b, an α5β1 targeting peptide. PEGibody generation involved PEGylation and self-assembly. [64Cu]QM-2303 PEGibodies displayed spherical nanoparticles ranging from 100 to 200 nm in diameter. Compared with non-PEGylated radioligands, [64Cu]QM-2303 demonstrated enhanced tumor retention time due to increased binding affinity and stability. Importantly, the biodistribution analysis confirmed rapid clearance of [64Cu]QM-2303 from the bloodstream. Administration of a single dose of [177Lu]QM-2303 led to robust antitumor efficacy. Furthermore, [64Cu]/[177Lu]QM-2303 exhibited low hematological and organ toxicity in both healthy and tumor-bearing mice. Therefore, this study presents a PEGibody-based radiotheranostic approach that enhances tumor retention time and provides long-lasting antitumor effects without prolonging blood circulation lifetime. The PEGibody-based radiopharmaceutical [64Cu]/[177Lu]QM-2303 shows great potential for positron emission tomography imaging-guided targeted radionuclide therapy for α5β1-overexpressing tumors.

OBJECTIVE To evaluate the medication adherence of patients with hypertension in medication consultation clinics, and to analyze its influencing factors. METHODS The data of 389 patients who visited the medication consultation clinics of our hospital from June 2021 to June 2023 were collected. Univariate and multivariate Logistic regression analysis were used to analyze the related factors affecting medication adherence of hypertensive patients or those receiving different types of drugs. RESULTS Among 389 patients with hypertension, 302 cases (77.63%) had good adherence. Multivariate Logistic analysis showed that higher education level [corrected OR=2.25, 95%CI (1.29, 3.93), P=0.004] was positively correlated with medication adherence, average blood pressure level [corrected OR=0.19, 95%CI (0.10, 0.37), P<0.001], without complication [corrected OR=0.47, 95%CI(0.26,0.84),P=0.010] and antihypertensive drug regimen being free dose combination [corrected OR=0.27,95%CI(0.15, 0.47), P<0.001] were negatively correlated with adherence. Results of univariate Logistic regression analysis showed that patients who used β-receptor blocking agents [OR=1.65,95%CI(1.06,2.57),P=0.027], calcium channel blockers [OR=2.13,95%CI(1.33, 3.42),P=0.002] and agents acting on the renin-angiotensin system [OR=2.04,95%CI(1.29,3.22),P=0.002] had good medication adherence. CONCLUSIONS The medication adherence of hypertension patients needs to be improved. Hypertension patients with higher education level, lower average blood pressure level, complications and fixed-dose combination regimen and those who use agents acting on the renin-angiotensin system, calcium channel blockers and β-receptor blocking agents may have better medication adherence.
