Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 70 years

  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Male and female subjects, age 18 to 70 years on the date of informed consent.

A highly effective method of birth control is defined as one that results in a low failure rate (i.e. less than 1 percent per year) when used consistently and correctly, such as implants, injectables, combined oral contraceptives, some intrauterine devices (IUDs), sexual abstinence, or a vasectomized partner.

[Note: inhaled corticosteroids and chronic low-dose corticosteroids [≤ 7.5mg per day] are permitted as are brief pulsed corticosteroids for intermittent symptoms (e.g. asthma).]
  • Subjects with uncontrolled diabetes (defined as metabolically unstable by the PI), incapacitating cardiac and/or pulmonary disorders.
  • History of active alcohol and/or drug abuse that in the investigator's assessment would impair the subject's ability to comply with the protocol.
  • Subjects with an albumin value < 25 g/L, and albumin/creatinine ratio greater than 3500mg/g at Screening or prior to Biopsy.
  • Patients with clinically significant hepatic disease (ALAT or ASAT > 5.0 x ULN) at Screening.
  • Patients with bleeding disorders or patients taking Coumarins (e.g.,Warfarin).
  • Any circumstance in which the investigator deems participation in the study is not in the subject's best interest.
  • Use of any investigational product (drug, biologic, or device) within 5 half-lives (drug, biologic) or 3 months, whichever is longer, without receiving prior written consent of the Medical Monitor.-

About this study

Official title: A Phase 1, Open-Label Safety and Delivery Optimization Study of an Autologous Neo-Kidney Augment (NKA) in Patients With Chronic Kidney Disease (CKD)

The primary purpose of this study is to assess the safety and optimal delivery of the Neo-Kidney Augment (NKA) when implanted at one site in a recipient kidney. NKA is made from expanded autologous, homologous, selected renal cells (SRC) obtained from the patient's kidney biopsy.

Read the detailed description

Therapeutic intervention with NKA is intended to delay the need for renal replacement therapy (dialysis or transplant) which at this time, is inevitable in patients with CKD. NKA is composed of autologous, homologous selected renal cells (SRC) formulated in a Biomaterial (gelatin-based hydrogel). SRC are the biologically active component of NKA. Proof of principle for SRC as the biologically active component of NKA was established in multiple models of CKD. Based on nonclinical efficacy and safety data, a single NKA dose will be delivered to patients in this FIH clinical trial. This dose provides a minimum of a 1.5-fold safety margin over doses delivered safely in nonclinical studies. In addition, this dose demonstrated efficacy in a nonclinical disease model.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Occurrence of procedure and/or product related adverse events

    The primary endpoint of the study is the occurrence of procedure and/or product related adverse events (AEs) through three months post-implantation. The primary outcome measures are procedure- and/or NK product-related AEs through 3 months post-implantation. Procedure related AEs include events considered related to the surgical procedures, biopsy or implantation of NKA including HARS, and not to other study-specific procedures (e.g., MRI or blood draws).

    Measured: Between screening visit and 3 months post-implantation

Secondary outcomes (1)
  1. Change in the rate of renal disease progression

    The secondary endpoint of the study is the change in the rate of progression of renal insufficiency, as measured by laboratory tests of renal function. The secondary outcome measures are laboratory assessments of renal function to assess changes in the rate of progression of renal insufficiency for each patient. Specifically, eGFR (based on cystatin-C and iohexol clearance), sCr, and ACR will be followed for 6 months to assess the post-implant rate of change compared to pre-implant changes.

    Measured: Baseline and 6 months post-implantation

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Implantation of SRC in people with Chronic Kidney Disease, run by Tengion at 2 sites in Sweden.

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 8 inclusion and 27 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: stopped early, as of the sponsor's last update on 11 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: lack of funding). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Occurrence of procedure and/or product related adverse events (time frame: Between screening visit and 3 months post-implantation). 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 11 Dec 2014.
