Exploration of Treatment Effect of Novel Hormone Therapy Combined With Local Treatment Based on PSMA PET/CT Evaluation in mHSCP Patients

March 20, 2026 updated by: Han Bangmin, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine
At present, there is still controversy over the treatment of metastatic hormone sensitive prostate cancer (mHSPC). Major guidelines and consensus suggest that novel hormone therapy (NHT) should be used as the basic treatment for mHSPC, and metastasis directed therapy can be combined depending on the clinical situation. However, it is still unclear how to develop more specific and individualized treatment plans for mHSPC patients. On the other hand, prostate-specific membrane antigen (PSMA) which is highly specifically expressed in prostate epithelial cells has been widely used as a PET/CT target for the diagnosis and staging of prostate cancer. However, there is still a lack of clinical evidence on how to use it to guide the treatment of prostate cancer. Therefore, this study intends to include patients diagnosed with mHSPC by PSMA PET/CT. The patients received no prior treatment for prostate cancer or ADT plus NHT therapy only. After 8 months of ADT plus NHT, PSMA PET/CT will be re-evaluated and patients with remaining active lesions on PSMA PET/CT will be included for randomization. The aim of this study is to explore the effect of NHT combined with local treatment on delaying disease progression and prolonging survival in patients with active lesions on PSMA PET/CT after NHT, providing new insights into the treatment of mHSCP patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Progression free survival, PFS
Time Frame: From enrollment to the end of treatment at 12 weeks
Progression includes biochemical progression, clinical progression, and imaging progression. The definition of biochemical progression is a PSA increase of more than 25% and an absolute increase of 2ng/ml compared above baseline or nadir. The definition of clinical progression is the emergence of any new clinical symptoms related to the primary and metastatic lesions of prostate cancer. The definition of imaging progression is the appearance of any new metastatic lesion in CT/MR/PET/CT scan. When one of the above criteria is met, it can be considered as disease progression.
From enrollment to the end of treatment at 12 weeks
