Prospective Clinical Trial of 225Ac-LNC1011 in the Treatment of Metastatic Castration-Resistant Prostate Cancer

Description:

PSMA is an ideal target for precision diagnosis and treatment of prostate cancer. LNC1011 is a novel albumin-binding PSMA-targeted radioligand. This study aims to explore the safety and efficacy of 225Ac-labeled LNC1011 for treating patients with PSMA-positive metastatic castration-resistant prostate cancer (mCRPC).

Inclusion
  • Metastatic Castration-Resistant Prostate Cancer (mCRPC) mCRPC refers to prostate cancer that progresses despite serum testosterone at castrate levels (\< 50 ng/dL or 1.7 nmol/L), meeting at least one of the following criteria:
  • PSA \>1 ng/mL with two consecutive rises at least 1 week apart, each increase ≥50% above the nadir.
  • At least one measurable lesion per RECIST 1.1 criteria OR at least one bone metastasis per PCWG3 criteria.
  • Radiographic progression: Either two or more new bone lesions on bone scan, or soft tissue lesion progression as per RECIST 1.1 criteria. Progression based on symptoms alone is insufficient for mCRPC diagnosis and requires further evaluation.
  • Presence of high-uptake lesions confirmed by 68Ga-PSMA-11 PET/CT imaging (positive defined as lesion uptake \>1.5 times the liver background).
Exclusion
  • Brain metastasis at screening, except:
  • Prior EBRT involving extensive bone marrow (\>25%);
  • Patients who received radionuclide therapy (Strontium-89, Samarium-153, Rhenium-186, Rhenium-188, Radium-223, Lutetium-177) within 6 months, or any External Beam Radiation Therapy (EBRT) within 2 months prior to the first dose;
