Using apalutamide and 89Sr to treat prostate cancer with bone metastases

Efficacy and Safety of Apalutamide in Combination With 89Sr as Neoadjuvant Therapy in Prostate Cancer With ≤10 Bone Metastases

Not applicable Interventional Zhujiang Hospital · NCT05740488

This study is testing if a combination of apalutamide and 89Sr can help men with prostate cancer that has spread to the bones live longer without their cancer getting worse before surgery.

What this trial studies

This study evaluates the effectiveness and safety of apalutamide combined with 89Sr as a neoadjuvant therapy for patients with prostate cancer that has up to 10 bone metastases. The primary goal is to assess progression-free survival (PFS), while secondary goals include measuring pathological complete response (pCR), radiographic PFS (rPFS), prostate-specific antigen (PSA) response, pain levels, and the number and extent of bone metastases. Participants will undergo laparoscopic radical prostatectomy and pelvic lymphadenectomy, along with preoperative and postoperative endocrine therapy. The study aims to provide insights into a potentially effective treatment regimen for this specific patient population.

Who should consider this trial

Good fit: Ideal candidates include men diagnosed with prostate cancer who have confirmed bone metastases of 10 or fewer and are eligible for surgery.

Not a fit: Patients with other organ metastases, severe comorbidities, or those who have had prior treatments for other tumors may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve survival rates and quality of life for patients with prostate cancer and limited bone metastases.

How similar studies have performed: While there is ongoing research in this area, the combination of apalutamide and 89Sr as neoadjuvant therapy for this specific condition is relatively novel and has not been extensively tested.
