Study summary

A study to investigate safety, tolerability, and pharmacokinetics of AZD1613 following subcutaneous or intravenous administration in participants with autosomal dominant polycystic kidney disease (ADPKD).

Read the detailed description

This Phase I, randomised, single-blind, placebo-controlled study will assess the safety and tolerability of AZD1613 and characterise the pharmacokinetics (PK) of AZD1613 in participants with autosomal dominant polycystic kidney disease (ADPKD), following subcutaneous (SC) or intravenous (IV) administration. Inclusion of participants receiving placebo is appropriate for benchmarking the safety and tolerability of AZD1613. Furthermore, the safety and PK profile will be evaluated in Chinese participants with ADPKD to assess any potential race effect in this population.

Inclusion criteria

  • Patients with ADPKD Mayo Class (IB-IE), as per clinical diagnosis (MIC) assessed centrally. Genetic testing results will not be used for eligibility purposes
  • = 45 to 90 mL/min /1.73m2
  • Body weight ≥ 45 kg and within the range 18 to 35 kg/m2 (inclusive).

Exclusion criteria

Exclusion Criteria:

  • As judged by the investigator, any evidence of cardiac, vascular, and other renal conditions which in the investigator's opinion makes it undesirable for the participant to participate in the study.
  • Positive antibody, virus surface antigen, or test, at screening.
  • History of associated with other medications that required discontinuation of that medication.
  • Congenital long QT syndrome.
  • History of ventricular arrhythmia requiring treatment. Patients with atrial fibrillation/flutter and controlled ventricular rate HR \< 100 bpm can be eligible as judged by the investigator.
  • below the lower limit of the normal range or any other haematological abnormality as judged by the investigator.
  • Any clinically important abnormalities in clinical chemistry, haematology, coagulation, or urinalysis results other than those specifically described as exclusion criteria herein, as judged by the investigator.
  • Systolic BP > 160 mmHg or diastolic BP > 100mmHg or HR \< 50 bpm or > 100 bpm at screening. Patients taking anti-hypertensive medication should be on a stable treatment regimen of antihypertensive therapy for at least 30 days prior to the screening visit.
  • Any clinically important abnormalities in rhythm, conduction, or morphology of the resting and any abnormalities in the 12-lead ECG that, as considered by the investigator, may interfere with the interpretation of QTc interval changes, including abnormal ST-T-wave morphology or left ventricular hypertrophy.
  • Kidney cyst interventions such as cyst aspiration or cyst fenestration within 12 weeks prior to screening and during the screening period, or such interventions planned or anticipated within the follow-up period.
Terms in these criteria, in plain language(10)

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.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

HIV

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.

QT and QTc

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.

Hemoglobin (Hb)

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).

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
