Your patients with metastatic castration-resistant prostate cancer (mCRPC) are invited to join ECLIPSE

Participating in this 177Lu-PSMA-I&T trial presents an investigational therapy option for your patients that may help advance innovation in mCRPC treatment


Mechanism of action

Targeting PSMA can initiate cell death

Prostate-specific membrane antigen (PSMA) is an attractive target because it is highly expressed on the cell surface of prostate cancer tumors1

When 177Lu-PSMA-I&T binds to the extracellular portion of PSMA, it is taken into the cell, where the radiation causes DNA damage to initiate cell death2


The purpose of this study is to compare the safety and efficacy of 177Lu-PSMA-I&T versus standard-of-care hormone therapy in patients with metastatic castration-resistant prostate cancer.


Study design

A multicenter, open-label, randomized phase 3 trial comparing the safety and efficacy of 177Lu-PSMA-I&T versus hormone therapy in patients with metastatic castration-resistant prostate cancer, previously treated with only one ARAT and are taxane-based chemonaive.

  • Overall survival
  • Second radiographic progression
  • Progression-free survival (PFS, composite)
  • Progression-free survival 2 (PFS2, composite)
  • PSA50 response rate
  • Impact on skeletal symptoms
  • Change in use of chemotherapy
  • Quality of life
  • Safety

  • Objective response rate
  • Disease control rate
  • Time to PSA progression
  • Duration of response
  • Pharmacokinetics and dosimetry

Patients will be randomized using a 2:1 ratio of study medication to standard of care

This trial is a crossover study in which those patients randomized to the standard-of-care arm may have the option to receive the study drug if disease progression is detected while on standard-of-care hormone therapy.

The typical patient journey and the potential path to 177Lu‑PSMA‑I&T therapy


Patients may follow similar paths, yet every treatment journey is different. Your patients may qualify for this trial; however, specific requirements will need to be met.

Major inclusion criteria

  • Proven metastatic castration-resistant prostate cancer
  • Progressive disease while on androgen receptor-axis-targeted (ARAT) therapy (abiraterone, enzalutamide, darolutamide, apalutamide)
  • Positive PSMA PET scan

Major exclusion criteria

  • Previous treatment with more than one ARAT
