NCT04975841

Brief Summary

This is an open-label, single arm study evaluating the safety for patients with Inclusion Body Myositis. A total of 9 subjects will be enrolled in the study. Subjects will be randomized to Part 1 or Part 2 of the study in blocks of 3 every 3 months. Stem cell injections will be given in the forearm and thigh on either the left or right side of the body, depending on which side meets criteria. The overall goal of this pilot study is to test the safety of adipose derived regenerative cells in patients with Inclusion Body Myositis. If determined safe, this trial could lead to larger Phase II trials. While this specific trial's primary endpoint is safety, it our ultimate hope that ADRC injections into the forearm and thigh of IBM patients will slow, stabilize, or even reverse the progression of muscle weakness in patients with IBM.

Outcome Measures

Primary Outcomes (1)

  • Safety (Frequency and Severity of Adverse Events)

    The primary endpoint of safety will be reported as counts of subjects experiencing adverse events events (including abnormal laboratory results and vital signs). Six months after the first participant is treated, safety and efficacy will be accessed in order to make a decision about whether to continue the trial. Measures of safety will be reported for the last visit observed for each participant

    3 months post treatment

Secondary Outcomes (7)

  • Change in Inclusion Body Myositis Functional Rating Scale (IBMFRS) from Baseline

    6 months post treatment

  • Change in Modified Timed Up and Go (mTUG) from Baseline

    6 months post treatment

  • Change in Health Assessment Questionnaire-Disability Index (HAQ-DI) from Baseline

    6 months post treatment

  • Change in Patient Global Impression of Change from Baseline

    6 months post treatment

  • Change in Manual Muscle Testing (MMT) from Baseline

    3, 6, and 12 months post treatment

  • +2 more secondary outcomes

Study Arms (2)

Standard of Care

NO INTERVENTION

Standard of Care (SOC) Study: The 6 subjects in the late injection group will start on Part 1. - The Part 1 study subject participation is 12 months. Two subjects will be enrolled at each of Months 0, 3 and 6. This will include an initial assessment and SOC follow-up. Subjects will continue standard of care treatment. Part 1 study duration (with staggering included) will be 18 months. After Part 1, the late injection subjects may proceed to Part 2 depending on safety data from the early injection group (see 3. below).

Stem Cell Injection

ACTIVE COMPARATOR

Stem Cell Injection: The three subjects randomized to early injections will proceed directly to Part 2 with staggered enrollment of 1 subject every 3 months. Once the safety data of the first subject at Month 3 is assessed, the second subject will be enrolled. Once the safety data of the first 2 subject (Subject 1 at Month 6 and Subject 2 at Month 3) are assessed, the third early injection subject will be enrolled in Part 2.

Device: Adipose Derived Regenerative Cells

Interventions

The Cytori Celution technology is an automated version of the process and techniques used in the research laboratory to isolate regenerative cells from adipose tissue. The Cytori Celution System uses a proteolytic enzyme blend (Celase) to disrupt the adipose tissue matrix and release the entrapped adipose derived regenerative cells (ADRCs), also referred to in the literature as "stromal vascular fraction" cells. Once digested, the digestate is separated into fractions (buoyant adipocytes (fat cells) and pelleted ADRCs) by centrifugation. The non-buoyant cell pellet (ADRCs) is then washed and centrifuged through several cycles to remove residual enzyme reagent and cellular debris. Although the Cytori Celution technology replicates known laboratory techniques, it offers significant improvements to the manual laboratory technique by controlling the processing in a closed system that has been validated for safety, performance, and reproducibility.

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Demonstrate being able to arise from a chair without support from another person or device. Subjects may use their arms to push up.
  • Able to ambulate at least 20 ft/6 meters with or without assistive device. Once arisen from the chair, participant may use any walking device, i.e. walker/frame, cane, crutches, or braces. They cannot be supported by another person and cannot use furniture or wall for support.
  • Age at onset of weakness \> 45 years
  • Able to give informed consent
  • Muscle strength graded between 6 and 9 for finger flexion and knee extension unilaterally on one side of the body (right or left) using the Kandell 0-10 scale. A subject may meet this criterion bilaterally and still be included in the study.

You may not qualify if:

  • History of any of the following excludes subject participation in the study: chronic infection particularly HIV or Hepatitis B or C; cancer other than basal cell cancer less than five years prior, or other chronic serious medical illnesses.
  • Presence of any of the following on routine blood screening: WBC \< 3000; platelets \< 100,000; hematocrit \< 30%; BUN \> 30 mg/dL; creatinine \> 1.5 x upper limit of normal; symptomatic liver disease with serum albumin \< 3 g/dl
  • History of most recent creatine kinase \>15x the upper limit of normal without any other explanation besides IBM.
  • History of non-compliance with other therapies.
  • Use of testosterone except for physiologic replacement doses in case of androgen deficiency. Participants must have documented proof of the androgen deficiency.
  • Coexistence of any other neurological, cardiac, pulmonary, psychiatric, or rheumatologic disease that would likely to affect outcome measures.
  • Drug or alcohol abuse within past three months. Patient has recent history (within 6 months before Screening) of chronic alcohol or drug abuse which may compromise the patient's safety or ability to participate in study activities.
  • Use of cannabis
  • Participation in a recent drug study in the last 30 days prior to the screening visit or use of biologic agents less than 6 months prior to the screening visit.
  • Women who are lactating or pregnant, or men or women unwilling to use a highly effective method of birth control if not surgically sterile (defined as bilateral tubal ligation, bilateral oophorectomy, or hysterectomy for women; vasectomy for men) for both male and female participants until 4 weeks after last dose. Pre-menopausal women must have a negative pregnancy test prior to dosing with trial medication. Acceptable methods of birth control are:
  • i. Hormonal methods associated with inhibition of ovulation such as oral, implantable, injectable, or transdermal contraceptives for a minimum of 1 full cycle (based on the patient's usual menstrual cycle period) before IMP administration.
  • ii. Total abstinence from sexual intercourse since the last menses before IMP administration. (The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject. Periodic abstinence (calendar, symptothermal, post-ovulation methods), are not acceptable methods of contraception).
  • iii. Intrauterine device (IUD) or intrauterine hormone-releasing system (IUS). If the subject is a sexually active male with female partners of child-bearing potential (postmenarchal)\* he must use a condom with or without spermicide in addition to the birth control used by his partners during the trial until 3 months after the last dose of trial medication. \*Non child-bearing potential is defined as post-menopausal (minimum of 12 months with no menses and follicle-stimulating hormone in the post-menopausal range) or sterilisation (hysterectomy, oophorectomy, or bilateral tubal ligation).
  • Participants taking corticosteroids within the previous 30 days prior to screening. Participants on intravenous immunoglobulin (IVIg) or other immunosuppressants within the last 3 months. Topical, nasal, and ocular corticosteroids are allowed unless they are being widely applied or the severity of the underlying condition makes them unsuitable in the Investigator's opinion. Local steroid injections are allowed.
  • Patients who have aPTT (Activated Partial Thromboplastin Time) values ≥ 1.8 X the normal value.
  • +10 more criteria

Will share

During the conduct of the study, data about recruitment and data completeness will be shared with study personnel and appropriate regulatory and FDA oversight bodies. After completion of the study and analysis of the primary and secondary outcomes per protocol, a de-identified data set will be made available to any investigator interested in pursuing post-hoc analysis to aid in the overarching goal of bringing new therapies to IBM. Upon completion of the study data will be archived and listed with clinicaltrials.gov. In addition, data on process improvements will be made available to researchers interested in the innovations proposed in this study. KUMC will maintain a de-identified data set at completion which will be available to IBM researchers. We will ensure the results of the trial are widely distributed. At study completion we will announce the study in the The Myositis Association newsletter.
