Recruiting at 1 site in Spain. Open to participants aged 10 Months to 14 Months. Per ClinicalTrials.gov, last updated 2024-05-10.
Sponsored by Elisa María Cubiles Montero de Espinosa · Phase 1/2, Interventional, and Treatment
Phase I/II, controlled, open-label, randomized, single site clinical trial to assess the safety and feasibility, as well as hint efficacy evidence of a bioengineered palate mucosa substitute on nanostructured fibrin-agarose scaffolds with autologous mucosa tissue-specific cells (culture-expanded fibroblasts and keratinocytes), for tissue replacement and repair of donor area after the reconstruction of palate cleft defects (staphylorraphy), in comparison with standard care for donor mucosa.
The initial phase of the trial is non-randomized, and involves the sequential recruitment of 5 eligible subjects with a minimum safety period of 30 days between them. All of them will be implanted with the autologous human palatal mucosa substitute of nanostructured fibrin-agarose generated by tissue engineering (BIOCLEFT), after reconstruction of the palate. Once the 5th treated patient has reached 1.5 months of follow-up after the intervention (Visit 8), the safety and feasibility data analysis will be carried out by the Independent Data Safety and Monitoring Committee (interim analysis), after which will allow continuation to the randomized phase of the trial, if the results allow it.
In the second phase, the rest of the patients (10) will be recruited, who will be randomized 1:1, such that 5 of these patients will be implanted with the investigational medication while undergoing standard surgical reconstruction. (uranostaphyllorrhaphy), while the other 5 will only undergo standard surgical reconstruction and will constitute the control group.
The total number of patients to be included in the study will be 15, who will be followed for 24 months according to a protocolized scheme that includes 2 pre-implant visits, 1 implant visit and 9 post-implant evaluation visits.
168 studies on the registry are indexed under Cleft Lip; 51 are open to participants now.

Exclusion Criteria:
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.
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.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
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.
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 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.
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.

The experimental group will be implanted with an autologous human palatal mucosa substitute made of nanostructured fibrin-agarose generated by tissue engineering (BIOCLEFT). The implantation of this advanced therapy medication will cover the lateral defect generated by the mobilization of fibromucous flaps during standard surgery (uranostaphylorrhaphy
Procedure: implantation with an autologous human palatal mucosa substitute made of nanostructured fibrin-agarose generated by tissue engineering (BIOCLEFT).
These patients will be included in the control group and will receive the usual treatment for their disease (uranoestafilorrafia), without applying any type of restriction to the area used for the movement of the arms.
cleft palate repair surgery, all patients in the study will receive the standard treatment (uranostaphyllorrhaphy), with the only difference that patients assigned to the experimental study group will additionally have BIOCLEFT tissue obtained through tissue engineering grafted onto them. the lateral area of the palatine bone exposed when mobilizing the flaps. For the implant, the BIOCLEFT fabric will be placed in the area of exposed bone, sized to the size of the defect and sutured using uncoated, monofilament long-term absorbable synthetic suture.
