About this study
Official title: Randomized Controlled Study of Geranium Wilfordii Combined With Androgen Deprivation in Neoadjuvant Therapy for Prostate Cancer
The high incidence of prostate cancer is one of the important diseases that threaten the health of old men in our country. Although androgen deprivation therapy is an important treatment option for prostate cancer, although neoadjuvant androgen deprivation therapy combined with radical prostatectomy reduced the positive rate of surgical margins, it did not show statistically significant improvement in prostate-specific antigen (PSA). At the same time, few trials reported pathological complete response (pCR) and minimal residual lesion (MRD).
The purpose of this project is to verify the efficacy of geranium combined with androgen deprivation in the treatment of locally advanced prostate cancer or oligometastatic prostate cancer before radical prostatectomy through randomized controlled clinical trials, so as to find an effective treatment for locally advanced prostate cancer or oligometastatic prostate cancer.
Read the detailed description
This study will divide patients into two sections, and eligible patients will be enrolled. Patients with locally advanced prostate cancer or oligo-metastatic prostate cancer were divided into geranium combined androgen deprivation therapy group and androgen deprivation therapy group according to a computer-generated random sequence. In the treatment group, except for continuous androgen deprivation treatment, geranium geranium decoction was taken orally every day; The control group only received continuous androgen deprivation therapy, and the usage was the same as the treatment group. After starting the intervention, all patients should be followed up in our hospital 7, 14, 28, 56, 84 days after treatment to review blood PSA and other indicators. At the end of the treatment, imaging examinations were followed up and radical prostatectomy was performed 3 weeks later (±7 days).

What is being measured
The primary outcome is the main question the study is designed to answer.
pCR or MRD rate
pCR (pathological complete response) is defined as cancer that is not morphologically recognizable in a prostatectomy specimen; MRD (small residual lesion) was defined as the maximum cross-section size of the residual tumor ≤5 mm, and RCB (residual cancer load) ≤ 0.25cm3 (tumor volume ≤ 0.5cm3 × tumor cells ≤ 50%) was used to calculate the tumor volume through three-dimensional volume estimation according to the maximum cross-section size and number of cross-sections involved in the tumor. Correction of tumor cell structure;
Measured: up to 4 weeks
Secondary outcomes (3)
PSA level change
Measured: At the end of Cycle 1 and Cycle 2 (each cycle is 21 days)
Biochemical progression-free survival after radical prostatectomy
Measured: The evaluation period was up to 1 year ( from the date of completion of surgery to the date of first recorded psa progression)
Pathologic responses after radical prostatectomy (including positive surgical margin, tumor size, prostatic extension, seminal vesicle infiltration, and lymph node involvement)
Measured: up to 4 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Geranium wilfordii combined with androgen deprivation treatment, Androgen deprivation treatment and radical prostatectomy in people with Prostate CA, run by baotai Liang.
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 3 inclusion and 4 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 6 Mar 2025. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Contact resident doctor (China+18852069821, 2978793353@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
pCR or MRD rate (time frame: up to 4 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 6 Mar 2025.
