Study summary

A two-component therapeutic consisting of FCX-013 and veledimex for the treatment of localized scleroderma (or morphea). The first component, FCX-013, is autologous human fibroblasts genetically-modified using lentivirus and encoded for matrix metalloproteinase 1 (MMP-1), a protein responsible for breaking down collagen. FCX-013 is designed to be injected under the skin at the location of the fibrotic lesions where the genetically-modified fibroblast cells will produce MMP-1 to break down excess collagen accumulation. With the FCX-013 therapy, the patient will take an oral compound (Veledimex) to induce MMP-1 protein expression from the injected cells. Once the fibrosis is resolved, the patient will stop taking the oral compound which will stop further MMP-1 production from the injected cells. FCX-013 plus veledimex is being developed in anticipation of improving skin function in patients by resolving fibrotic lesions and normalizing dermal collagen production

Read the detailed description

Castle Creek is developing a two-component therapeutic product for the treatment of moderate to severe localized scleroderma (morphea). The first component is FCX-013, an autologous genetically modified human dermal fibroblast (GM-HDFs) cell product that is genetically modified with a lentiviral vector (LV) to express human matrix metalloproteinase 1 (MMP1). MMP1 is also known as interstitial collagenase or fibroblast collagenase and is an enzyme that under normal physiological conditions breaks down the extracellular matrix. Specifically, MMP1 breaks down interstitial collagens, types I, II and III. In addition, the FCX-013 cells are also transduced with genetic constructs that encode the RheoSwitch Therapeutic System® (RTS®) an inducible promotor system that in the presence of a small molecule activator ligand controls expression of the MMP1 gene. The RTS® is activated to express MMP1 by the oral administration of the small molecule component. The purpose of this open-label single arm Phase 1/2 study is to investigate the safety and effectiveness of FCX-013 plus veledimex.

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

  • Subject is an adult, ≥ 18 years of age with moderate to severe localized scleroderma/morphea with sclerotic lesions which have been unresponsive to standard of care therapy.
  • Subject has stable control of localized disease (clinically inactive) over the 3 months prior to Screening and through Baseline
  • Subject has not participated in previous clinical research study in the 3 months prior to Screening and through Baseline
  • Subject has provided informed written consent
  • Female subjects of and male subjects engaging in sexual activity that could lead to pregnancy agree to use adequate regimen
  • Subject is able to understand the study, cooperate with the study procedures and willing to return to the clinic for the required follow-up visits

Exclusion criteria

Exclusion Criteria:

  • Subject has a skin disorder other than localized scleroderma/morphea in the anatomical area of interest
  • Subject has localized scleroderma/morphea only located on the face or over a joint, or lesions that can be successfully managed with topical medications or phototherapy
  • Subject has symptoms consistent with systemic scleroderma that have not been stable, or that require treatment that has not been stable for 3 months prior to Screening and through Baseline
  • Subject has been treated with UVA1 phototherapy within 2 months prior to Baseline
  • Subject requires treatment with a non-stable regimen of systemic therapy, for any medical condition, or plans to initiate such treatment during the study period
  • Subject requires treatment with a non-stable regimen of physical therapy, for localized scleroderma/morphea, or plans to initiate such treatment during the study period.
  • Subject has any medical instability limiting ability to travel to the investigative center.
  • Subject has clinical signs of infection at (or in close proximity to) the target lesion.
  • Subject has a history of, or current, at/near site of injection (except basal cell carcinoma or squamous cell carcinoma that have been treated)
  • Subject has a history of, or current, clinically significant liver abnormalities.
  • Subject has a history of, or current, clinically significant cardiac abnormalities, or a significant abnormality on
  • Subject has clinically significant laboratory abnormalities
  • Subject has active infection with (HIV), or /C
  • Subject has an active drug or alcohol addiction
  • Subject has any known allergy to any of the constituents of the product
  • Subject has received an interventional chemical or biological study product for the specific treatment of localized scleroderma in the 3 months prior to Screening and through Baseline
  • Subject is pregnant or nursing or plans to become pregnant or nurse during the study period
Terms in these criteria, in plain language(9)

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.

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.

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.

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.

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.

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.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
