[Lu-177]Ludotadipep in Castration-resistant Prostate Cancer(CRPC): Investigation of Drug and Application

Conditions

Metastatic Castration-resistant Prostate Cancer

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Phase 1: The objective of the Phase 1 part of the clinical trial is to verify safety and tolerability (dose-limiting toxicity \[DLT\], maximum tolerated dose \[MTD\]) of a single 3.7 Giga-Becquerel (GBq) dose with the potential for one dose level de-escalation to 2.775 GBq if necessary, to determine the recommended \[177Lu\]Ludotadipep dose for use in the Phase 2a part of the trial. Phase 2a: The objective of the Phase 2a part of the trial is to evaluate safety and efficacy for repeated administration of the recommended \[177Lu\]Ludotadipep dose. The Recommended Phase 2 dose (RP2D) will be based on the study results from the Phase 1 trial in South Korea upon consultation with the FDA.

PSA progression as defined by a minimum of two rising PSA levels at least 1 week apart, ideally three successive measurements 2.

Bone disease progression defined by two or more new lesions on bone scan 4. Serum testosterone level \< 50 ng/dL (\< 0.5 ng/mL, \< 1.7 nmol/L). Patients may have ongoing androgen deprivation therapy (ADT) with a luteinizing hormone-releasing hormone (LHRH) "super-agonist" or antagonist, and/or be surgically or medically castrated. 5. Patients must have PSMA positive lesions. These are defined as having Ga 68-PSMA-11 uptake greater than that of liver parenchyma in one or more metastatic lesions of any size in any organ system. PSMA-negative lesions are defined as having PSMA uptake equal to or lower than that of liver parenchyma in any lymph node with a short axis of at least 2.5 cm, in any metastatic solid-organ lesions with a short axis of at least 1.0 cm, or in any metastatic bone lesion with a soft-tissue component of at least 1.0 cm in the short axis. 6. Patients receiving bisphosphonate therapy must have been on stable doses for at least 4 weeks prior to Day 1 7.

Able and willing to provide signed informed consent and comply with protocol requirements	1. Impaired organ function as evidenced by the following laboratory values at Screening: 1. Absolute neutrophil count \< 1500/μL 2. Platelet count \< 100,000/μL 3.

History of other malignancy within the previous 3 years, except basal cell or squamous cell carcinoma, or non-muscle invasive bladder cancer 6. History of active thromboembolism within the last 3 months of Day 1 7. Serious persistent infection within 14 days prior to Day 1 8. If the patient is known to have a positive polymerase chain reaction (PCR) test for active COVID-19 infection or signs or symptoms consistent with COVID-19, in the absence of a positive PCR test, within 5 days from date of consent 9. Patients with any medical condition or other circumstances that, in the opinion of the investigator, compromise obtaining reliable data, achieving study objectives, or completing the study 10. History of congestive heart failure New York Heart Association (NYHA) class III or IV, uncontrolled hypertension or evidence of coronary artery disease (including a myocardial infarction) within the previous 6 months from date of consent 11.

HIV infected patients who are healthy and have a low risk of Acquired Immune Deficiency Syndrome (AIDS)-related outcomes will be included. 2. Patients with a history of hepatitis B or C will be allowed to enrol if hepatitis B virus (HBV) DNA or hepatitis C virus (HCV) RNA are undetectable. At this early stage of development, about the main concern is the potential for re-activation or worsening of HBV or HCV from the effect of radiation on lymphocyte function. 23.
