About this study

Official title: A Phase III, Randomized, Open-Label, Parallel-Controlled, Multicenter Study to Evaluate the Efficacy and Safety of 177Lu-NYM032 Injection in Participants With Progressive, PSMA-Positive Metastatic Castration-Resistant Prostate Cancer (mCRPC)

The primary objective of this study is to compare overall survival (OS) in patients with progressive PSMA-positive mCRPC who receive 177Lu-NYM032 in addition to best supportive/best standard of care versus patients treated with best supportive/best standard of care alone.

Read the detailed description

Patients with PSMA positive scans will be randomized in a 2:1 ratio to receive either 177Lu-NYM032 plus best supportive/best standard of care or to receive best supportive/best standard of care only. Best supportive/best standard of care will be determined by the treating physician/investigator but will exclude investigational agents, cytotoxic chemotherapy, other systemic radioisotopes, and hemi-body radiotherapy. Novel androgen receptor pathway inhibitor (ARPI) (such as abiraterone or enzalutamide) are allowed.

This open-label study consists of a 12-month enrollment phase and a 24-month follow-up phase. During the whole study period, assessments will include monitoring of patient survival, disease progression, and adverse events.

A long-term follow-up period will include the collection of rPFS survival and information about new treatments, responses to new treatments, adverse events assessment, as well as blood for hematology and chemistry testing. During follow-up, patients will be contacted every 3 months (+/- 14 Days) via phone, email, or letter for 24 months or until 384 deaths have occurred.

An End-of-Treatment (EOT) visit should occur once a participant discontinues study treatment for any reason. This visit should occur within 7 days of the last dose of study treatment or the date the investigator becomes aware of treatment discontinuation (whichever occurs later), but before the initiation of any subsequent anticancer therapy.

A Safety Follow-up visit should occur 28 days (+7 days) after the participant's last dose of 177Lu-NYM032 Injection or the date the investigator becomes aware of treatment discontinuation (whichever occurs later), but before the initiation of any subsequent anticancer therapy outside of what is permitted by the study.

  3. Overall Response Rate (ORR)

    ORR is defined as the proportion of participants with Best Overall Response (BOR) of Complete Response (CR) or Partial Response (PR) according to PCWG3 modified RECIST 1.1

    Measured: From date of randomization until date of radiographic progression or date of death from any cause, whichever comes first, assessed up to 36 months (estimated final OS analysis)

  4. Disease control rate (DCR)

    DCR is defined as the proportion of participants with Best Overall Response (BOR) of Complete Response (CR) or Partial Response (PR) or Stable Disease (SD) in soft tissue according to PCWG3 modified RECIST 1.1

    Measured: From date of randomization until date of radiographic progression or date of death from any cause, whichever comes first, assessed up to 36 months (estimated final OS analysis)

  5. Duration of Response (DOR)

    DOR is defined as the duration of time between the date of first documented response (CR or PR) in soft tissue according to PCWG3 modified RECIST 1.1, and the date of first documented progression or death due to any cause

    Measured: From date of randomization until date of progression or date of death from any cause, whichever come first, assessed up to 36 months (estimated final OS analysis)

  6. Time to first Symptomatic Skeletal Event (SSE)

  11. European Quality of Life ( EuroQoL) -5 Domain 5 Level Scale (EQ-5D-5L)

    EQ-5D-5L is a standardized participant completed questionnaire that measures health-related quality of life and translates that score into an index value or utility score. EQ-5D-5L consists of two components: a health state profile and an optional visual analogue scale (VAS). EQ-5D health state profile is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: 1= no problems, 2= slight problems, 3=moderate problems, 4= severe problems, and 5= extreme problems. Higher scores indicated greater levels of problems across each of the five dimensions.

  12. Functional Assessment of Cancer Therapy - Prostate (FACT-P) Questionnaire

    FACT-P assesses symptoms/problems related to prostate carcinoma and its treatment. It is a combination of the FACT-General + the Prostate Cancer Subscale (PCS). The FACT-General (FACT-G) is a 27 item Quality of Life (QoL) measure that provides a total score as well as subscale scores: Physical (0-28), Functional (0-28), Social (0-28), and Emotional Well-being (0-24). The total score range is between 1-108, higher scores indicates better for total score and subscale scores. PCS is a 12-item prostate cancer subscale that asks about symptoms and problems specific to prostate cancer (Range 0-48, higher scores better). The FACT-P total score is the sum of all 5 subscale scores of the FACT-P questionnaire and ranges from 0-156. Higher scores indicate higher degree of functioning and better quality of life

    Measured: From date of randomization till 30 days safety follow-up, assessed up to 36 months (estimated final OS analysis)

  13. Brief Pain Inventory-short Form (BPI-SF)

    The BPI-SF is a publicly available instrument to assess the pain and includes severity and interference scores. BPI-SF is an 11-item self report questionnaire that is designed to assess the severity and impact of pain on daily functions of a participant. Pain severity score is a mean value for BPI-SF questions 3, 4, 5 and 6 (questions inquiring about the extent of pain, where the extent is ranked from 0 [no pain] to 10 [pain as bad as you can imagine]). Pain severity progression is defined as an increase in score of 30% or greater from baseline without decrease in analgesic use

    Measured: From date of randomization till 30 days safety follow-up, assessed up to 36 months (estimated final OS analysis)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 177Lu-NYM032 injection in people with Prostate Cancer, run by Norroy Bioscience Co., LTD.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 26 inclusion and 30 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 31 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Survival (OS) (time frame: From date of randomization until date of death from any cause, assessed up to 36months (estimated final OS analysis)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07795268.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Aug 2026.
