Description

[Technical field]

[0001] The present disclosure relates to prostate specific membrane antigen (PSMA) ligands. In particular, the present disclosure relates to ligands for glutamate. GUL moieties, radioisotopes, and radiometals The present invention relates to a PSMA ligand having a chelator that can include a chelator having a chelator capable of containing a PSMA ligand.

[0002] The present disclosure also relates to the use of these compounds in the imaging and treatment of prostate cancer. Also relates to. [Background technology]

[0003] Theragnostics is a patient management strategy that involves the integration of diagnostic and therapeutic methods.

[0004] In the context of nuclear medicine, theragnostics involves the use of diagnostic radioactive metals (e.g., positrons or gamma emitters) or therapeutic radiometals (e.g. beta emitters). This refers to the use of targeted molecules for the diagnosis and therapy of specific diseases. The present invention relates to a method for detecting a target molecule having high affinity for a receptor expressed on a tumor cell, comprising: Radiolabeling with gallium Ga-68 for therapeutic purposes or lutetium Lu-177 for therapeutic purposes. Therefore, the same molecular targeting compounds can be used for molecular imaging and disease diagnosis. It is possible to effectively carry out individualized treatment using the substance.

[0005] This use of the same target compound also allows for a more thorough approach to patient management. This diagnostic method also has several simultaneous roles, using the same molecule labeled with radionuclides for diagnosis, reproduction, monitoring and therapy. This is because it allows the selection of the appropriate therapy or a different treatment plan, and allows follow-up after treatment. do.

[0006] For patients, theragnostics result in more effective medical care and less unnecessary treatment. Reduce or eliminate medical treatment and tailor therapeutic interventions to patients who will benefit most. Patients may not respond to unnecessary treatment or may otherwise experience side effects. By predicting which patients will experience It will be not only comprehensive but also patient-centered.

[0007] For physicians, theragnostics is the optimal therapy for diagnosing and staging disease. improve one's ability to select treatment options and monitor treatment outcomes and disease progression, The results suggest that the ability to predict outcomes may be improved safely and effectively. do.

[0008] For payers, theragnostic approaches are associated with suboptimal diagnostics and treatments. Reduce the costs associated with diagnosis and time required to diagnose and provide effective individualized treatment plans This allows patients to be treated.

[0009] Prostate cancer is one of the most prevalent cancers in the United States and Europe. Metastatic CRPC (mCRPC) is associated with poor prognosis and reduced quality of life.

[0010] Recently, PSMA ligand-based endo-radiotherapy has been rapy) is an example of a new trend in development for treating prostate cancer, and PSM Fraction A is overexpressed in primary cancer lesions and in soft tissue / bone metastatic disease. PSMA expression is considered a suitable target for imaging and therapy. The incidence appears to be even higher in the most aggressive castration-resistant variants, which may be due to They represent a patient population with high unmet medical need (March 2016). al et al.,Histol Histopathol,2004,Jul;19 (3):715-8;Mease et al.,Curr Top Med Chem ,2013,13(8):951-62).

[0011] Among the many small molecule ligands targeting PSMA, urea-based low-dose agents These agents have been the most extensively investigated in prostate cancer clinical evaluations and PR. Several of these agents have been shown to be suitable for RT therapy as targeting scaffolds. It has glutamate-urea-lysine (GUL).

[0012] Several radiolabeled small molecule inhibitors of PSMA have been designed based on this approach (K iess AP,Banerjee SR,Mease RC,et al.Prost ate-specific membrane antigen as a target t for cancer imaging and therapy.QJ Nuc l Med Mol Imaging.2015;59:241-268)

[0013] However, in some circumstances the use of diagnostic radiometals may be limited (6 (Problems due to availability of 8Ga and scattered production).

[0014] On the other hand, 68Ga has a physical half-life of only 68 minutes. PSMA-PET scans are preferably performed in-house to ensure sufficient tracer activity. Delivery to remote centers is difficult. As a result, large centers with many patients The center requires multiple production runs per day or multiple production units to be built simultaneously. It would require the relocation of facilities, which would increase costs. To overcome these limitations, we have used 18F-labeled PSMA tracers. Good. PET radiopharmaceutical specialty pharmacy with on-site cyclotron macy) can produce highly radioactive 18F at reasonable cost. The physical half-life of the PSMA tracer (110 min) also allows for centralized production and remote satellite 18F also has a lower positron energy than 68Ga, which may allow for delivery to light centers. It has a higher energy (0.65 vs. 1.90 MeV) and theoretically provides improved spatial resolution.

[0015] However, the development of alternative PSMA ligands is always desirable because and / or the development of alternative, diverse PSMA ligands suitable for use as therapeutics would be beneficial. Because it could become. Summary of the Invention
