Brief summary: This is an open label, two to three center study to evaluate the clinical efficacy and safety of 1 dose level of 2-hydroxypropyl-β-cyclodextrin (2-HPβCD) given intravenously in adult patients with type 2 diabetes with diabetic kidney disease (DKD) and proteinuria.

Detailed description: This is a Phase 2a, open label, two to three center study to evaluate the clinical efficacy and safety of 1 dose level of 2-hydroxypropyl-β-cyclodextrin (2-HPβCD) given intravenously in adult patients with type 2 diabetes with diabetic kidney disease (DKD) and proteinuria.

The study will be conducted at 2 - 3 sites in the United States of America (USA) and will screen a sufficient number of subjects to complete 8 participants meeting the inclusion/exclusion criteria outlined.

The study consists of up to a 2-week screening period, a 12-week treatment period and a 4-week follow-up period.

2. Male or female age 18 to 75 years inclusive, at the time of signing the informed consent.
3. Women of childbearing potential (WOCBP) and male subjects who are partners of WOCBP must agree to use an acceptable form of contraception during the study and for 30 days following the last dose of study drug.
4. Clinical diagnosis of type 2 diabetes as per guidelines.
5. Clinical diagnosis of diabetic kidney disease in the opinion of the principal investigator, or renal biopsy proven diabetic kidney disease without evidence of additional pathologic findings of alternative diagnosis.

   1. At screening, based on two 24-hour urine collections, geometric mean of two urinary albumin creatine ratios (UACR) ≥ 400 mg/g and ≤ 3500 mg/g.
   2. At screening, based on two first morning void urine collections, mean UACR ≥ 400 mg/g and ≤ 3500 mg/g.
   3. At screening, eGFR equal or greater than 30 and less than 90 mL/min/1.73 m\^2.
6. Body mass index (BMI) ≤ 40.0 kg/m\^2.
7. If on diabetes and anti-hypertensive medications:

   1. Angiotensin converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) inhibitors dose must be stable for 3 months before screening.
   2. Sodium-glucose co-transporter 2 (SGLT2) or GLP-1 receptor agonist or long-acting insulin dose must be stable for at least 3 months prior to screening.
   3. All other diabetes and anti-hypertensive medications must be at a stable dose for at least 3 months prior to screening.
8. Hemoglobin A1c (HbA1c) ≤10.0% at screening.
9. Willing to comply with IV administration of the study drug for 12 weeks and all protocol procedures during the study.

Exclusion Criteria:

1. Has a solitary kidney.
2. Has a positive drug screen.
3. Known kidney disease other than diabetic kidney disease.
4. End stage renal disease (ESRD) (i.e., peritoneal dialysis, hemodialysis, or history of kidney transplantation).
5. Acute kidney injury or dialysis within the last 3 months before the screening visit.
6. Uncontrolled diabetes as defined by HbA1c \>10 at screening.
7. Uncontrolled hypertension with systolic blood pressure (SBP) \>140 mmHg or diastolic blood pressure (DBP) \>90 mmHg during screening.
8. Unstable cardiovascular disease or history of myocardial infarction or arterial thromboembolic events within 3 months prior to screening or severe or unstable angina, New York Heart Association (NYHA) Class III or IV disease, or a QTc interval \>480 msec.
9. Patients on IV medication containing cyclodextrin.
10. Patients on steroids.
11. Surgery within the past 3 months prior to the first study drug administration determined by the Investigator to be clinically relevant.
12. Known malignancy that is progressing or has required active treatment within the past 3 years. Any exceptions must be approved by the Medical Monitor.

    a. Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ (e.g., breast carcinoma, cervical cancer in situ) that have undergone potentially curative therapy are not excluded.
13. Known history of Human Immunodeficiency Virus (HIV) infection (HIV 1/2 antibodies).
14. Known active Hepatitis B (defined as Hepatitis B surface antigen \[HBsAg\] reactive) or known active Hepatitis C virus (defined as HCV RNA \[qualitative\] is detected) infection.

16. History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the participants' participation for the full duration of the study, or is not in the best interest of the participants to participate in the opinion of the treating Investigator.
