A Phase 2 interventional study of MBM-02 in Prostate Cancer Recurrent and Biochemical Recurrent Prostate Cancer, sponsored by Matrix Biomed, Inc.. Status unknown at 1 site in United States. Open to male participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2021-05-06.
Sponsored by Matrix Biomed, Inc. · Phase 2, Interventional, and Treatment
This is an open label trial to assess the efficacy of MBM-02 (Tempol) as a treatment for patients diagnosed with prostate cancer in biochemical recurrence.
Preliminary data shows MBM-02 has anti-prostate cancer activity without hormone suppression or toxicity to non-cancerous cells and organs.
Solid tumors contain hypoxic regions (low oxygen) due to their high rates of cell proliferation and formation of aberrant blood vessels. Intratumoral hypoxia is associated with increased risk of invasion, metastasis, and patient mortality. Cancer cells respond to hypoxia by stabilizing hypoxia-inducible factor 1 (HIF-1) and hypoxia inducible factor 2 (HIF-2). HIF-1 and HIF-2 activate a transcription of genes encoding proteins that mediate major adaptive responses to hypoxia that are critical for cancer cell survival. Without activation of HIF-1 and HIF-2, cancer cells would not survive.
MBM-02 has been shown to inhibit the genes responsible for prostate carcinogenesis, HIF-1 and HIF-2.
This trial is an open label study that will employ a 3+3 escalation design up to 1600 mg/day. Patients will be exposed to study drug for 20 weeks. PSA and scans will be taken at baseline and week 20 for efficacy.
7,046 studies on the registry are indexed under Prostatic Neoplasms; 1,580 are open to participants now.
This study's planned enrollment of 55 is close to the median of 60 across 5,348 interventional studies indexed under Prostatic Neoplasms.

Patient must have evidence of biochemical failure after primary therapy and subsequent progression. Biochemical failure is declared when the PSA reaches a threshold value after primary treatment and it differs for radical prostatectomy or radiation therapy:
Hematology:
(ANC) ≥1.5 ≥ 10 g/dL ≥ 100,000 per microliter of blood
Hepatic:
Total ≤ 2 x (ALT) and Aspartate aminotransferase (AST) ≤2.5 x ULN
Renal:
(CrCl) ≥ 60 ml/min within 2 weeks prior to registration determined by 24-hour collection or estimated by Cockcroft-Gault formula: CrCl male = [(140 - age) x (wt in kg)] [(Serum Cr mg/dl) x (72)] CrCl female = 0.85 x (CrCl male)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Start is estimated for May 2021; primary completion for Sep 2022, 16 months later.
Of 114 industry-sponsored phase 2 interventional studies under Prostatic Neoplasms, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 21 and three quarters within 45. This study's planned 16 months is below that.
Counting every sponsor, half of 724 studies reached it within 53 months; a quarter within 34 and three quarters within 80.
