Study summary

The DOSED clinical study evaluates the safety and utility of a novel delivery device to deliver LCTOPC1, a cell therapy, to the spinal cord of patients with a spinal cord injury (SCI). LCTOPC1 is designed to replace or support cells that are absent or dysfunctional due to traumatic injury, with a goal to help improve the quality of life and restore or augment functional activity in persons suffering from a traumatic cervical or thoracic injuries.

Read the detailed description

LCTOPC1-SCI-03 DOSED study is a Phase 1b, open-label, multi-center, device safety study designed to assess the safety of a novel delivery device for administering a one-time injection of LCTOPC1. The study will enroll 3-5 participants with subacute (21 to 42 days post-injury) spinal cord injuries and 3-5 participants with chronic (1 to 5 years post-injury) spinal cord injuries. Eligible participants must have either sensorimotor complete (AIS-A) or motor complete / sensory incomplete spinal cord injuries (AIS-B), located in the cervical (C4-C7) or thoracic (T1-T10) regions. The first four patients will be enrolled sequentially subsequent to meeting safety requirements. Participants will be monitored for long-term safety for up to 10 years following the administration of LCTOPC1.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Sensorimotor complete, traumatic SCI (ASIA Impairment Scale A) or sensory incomplete, traumatic SCI (ASIA Impairment Scale B)
  2. For subjects with subacute injury, International Standards for Neurological Classification of SCI (ISNCSCI) Neurological Level of Injury (NLI) from C-4 to T-10 occurring 21 to 42 days prior to LCTOPC1 injection
  3. For subjects with chronic injury, ISNCSCI NLI from C-4 to T-10 and more than 30 days without clinical improvement from last assessment, occurring 1 to 5 years prior to LCTOPC1 injection
  4. Individuals must have at least one upper extremity ISNCSCI key muscle with at least 1/5 strength
  5. 18 through 65 years of age, inclusive, at time of consent
  6. Single injury with sufficient visualization of the spinal cord injury epicenter and lesion margins to enable post-injection safety monitoring
  7. for this protocol must be provided and documented (i.e., signed ICF)
  8. Able to participate in an elective surgical procedure to inject LCTOPC1 21 days or later following SCI
  9. Female subjects of must agree to the use of for 1 year following LCTOPC1 injection; male subjects must agree to use contraception to prevent pregnancy in any female partners of child-bearing potential for 1 year following LCTOPC1 injection

Exclusion criteria

Exclusion Criteria:

  1. SCI due to penetrating trauma
  2. Traumatic anatomical transection, laceration, or inadequate decompression of the spinal cord based on prior surgery or MRI
  3. Any concomitant injury that interferes with the performance, interpretation, or validity of neurological examinations, such as multiple spinal cord lesions, brachial/lumbar plexus injury, cauda equina injury or traumatic brain injury
  4. Subjects with a cavity structure that would preclude successful transplantation, as identified on MRI, which may include septations or irregularities in tissue structure
  5. Persons with syringomyelia, defined as those with progressively enlarging cysts on T2-weighted images associated with neurological decline
  6. Inability to communicate effectively with neurological examiner such that the validity of patient data could be compromised
  7. Organ damage or systemic disease that would create an unacceptable risk for surgery or
  8. Need for mechanical support of ventilation (ventilator, continuous positive airway pressure [CPAP], bi-level positive airway pressure [BiPAP]), excluding supplemental oxygen, at baseline
  9. History of any (except non-melanoma skin cancers). For cancers in remission for more than five years, enrollment is allowed with concurred documented approval of principal investigator, oncologist, and Sponsor's medical monitor prior to enrollment
  10. Pregnant or nursing women
  11. Subjects with an implanted spinal cord stimulator (SCS), whether temporary or permanent.
Terms in these criteria, in plain language(5)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

    Frequency and severity of the MI PSD System or injection procedure related adverse events (AEs) through 30 days (1 month).

    Time frame: One month after LCTOPC1 injection

Secondary outcomes

  1. Frequency and Severity of Adverse Events Related to LCTOPC1 and/or the Concomitant Immunosuppression Through 90 Days

    Frequency and severity of AEs through 90 days (3 months) following injection of LCTOPC1 and/or the concomitant immunosuppression administered.

    Time frame: Three months after LCTOPC1 injection

  2. Incidence of MRI Findings Indicative of Deterioration or Safety-Related Changes at 90 Days

    Incidence of MRI findings indicative of deterioration or safety-related changes at 90 days post-administration of LCTOPC1. Central radiologists will assess MRI data for the presence and severity of: (1) Intramedullary hemorrhage, CSF leak, epidural abscess, or infection; (2) Expanding cyst or mass at the injection site or elsewhere in the CNS; (3) Inflammatory lesions at the injection site or elsewhere in the CNS; (4) CSF flow obstruction. Severity will be categorized as \[mild, moderate, severe\] based on predefined radiological criteria.

    Time frame: Three months after LCTOPC1 injection

Individual participant data

Plan to share: No — At this time, we do not plan to share IPD from this study. As this is a Phase 1 safety study with a small sample size, the data are primarily focused on initial safety assessments and sharing IPD is not anticipated to provide significant additional value. However, summary-level results will be made available in accordance with regulatory guidelines.

No publications or documents are linked to this record.
