Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
1. Aged 18 to 90 (inclusive) at screening;

4. Fasting plasma glucose < 21 mmol/L;
5. Must be receiving a stable dose of 300 mg daily of irbesartan (in any marketed formulation) for at least 3 months prior to screening, and have no plan to change treatment regime throughout the study;
6. Patients can be on stable doses of angiotensin converting enzyme inhibitors, aldosterone inhibitors, and/or sodium-glucose co-transporter-2 inhibitors. However, the dose and regimen must be stable for 3 months prior to screening and must have no plan to change treatment regime throughout the study;
7. Mean of two albumin creatinine ratio (ACR) values (screening and baseline) of more than or equal to 265 to 4,425 mg/g (30-500 mg/mmol) and within 30% of the screening value at the baseline assessment;

A high follicle stimulating hormone [FSH] level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy; however, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient.);
* Of childbearing potential and agrees to use a highly effective method of contraception consistently during the treatment period and for at least 60 days after the last dose of investigational product;
11. A male patient with a female partner of childbearing potential is eligible to participate if he agrees to use acceptable contraception during the treatment period and for at least 60 days after the last dose of investigational product and refrains from donating sperm during this period;

Summary
Brief summary
This study will be evaluating the safety and efficacy of propagermanium for the treatment of participants with DKD who are already taking irbesartan by:

* monitoring symptoms that participants may experience while on the study,
* measuring levels of protein in participant's urine and kidney function during the course of the study,
* measuring the levels of propagermanium and irbesartan that enters into participant's urine and blood, and
* comparing the propagermanium outcomes to participants' pre-study and placebo outcomes.

Eligible participants will randomly be assigned to one of two arms to receive both the propagermanium and placebo in different orders as follows, either:

Treatment Period 1 taking a propagermanium capsule twice a day for 12 weeks, followed by a six week washout period followed by Treatment Period 2 taking a placebo capsule twice a day for 12 weeks.

OR Treatment Period 1 taking a placebo capsule twice a day for 12 weeks, followed by a six week washout period followed by Treatment Period 2 taking a propagermanium capsule twice a day for 12 weeks.
