E.3 | Principal inclusion criteria |
Patients must meet criteria 1 and any of those in group 2: 1. Onychomycosis of the hands or feet, as demonstrated by the positivity of any of the following: direct examination, culture (with growth of dermatophytes, yeasts or fungi non-dermatophytes) or nail plate biopsy (PAS + structures, suggestive of fungi inside the nail plate). 2. Patients in the acceptable use of placebo: a) previously treated without success. b) with liver disease, kidney failure, or other comorbidities that increase the risk of systemic antifungal treatments. c) allergy or intolerance to systemic antifungal therapy. d) patients who express reluctance to systemic treatment and / or prolonged topical and prefer to participate in the EC. |
Los pacientes deben cumplir el criterio 1 y alguno de los del grupo 2, para que se les pueda solicitar su participación: 1. Que tengan onicomicosis en manos o pies, demostrada por la positividad de alguna de las siguientes pruebas (que se realizarán a todos los pacientes): examen directo, cultivo (con crecimiento de dermatofitos, levaduras u hongos no-dermatofitos) o biopsia de lámina ungueal (estructuras PAS+, sugestivas de hongos en el interior de la lámina ungueal). 2. Pacientes en los que sea aceptable el empleo de placebo: a) tratado anteriormente sin éxito. b) con hepatopatía, insuficiencia renal, u otras comorbilidades que aumentan el riesgo de los tratamientos antifúngicos sistémicos. c) alergia o intolerancia a los tratamientos antifúngicos sistémicos. d) pacientes que manifiesten reticencia a un tratamiento sistémico y/o tópico prolongado y que prefieran participar en el EC. |

E.4 | Principal exclusion criteria |
1. Patients under 18 years. 2. Inability or unwillingness of the natural or legal person / representative to give written informed consent. 3. Pregnant or breastfeeding. 4. Patients with diseases that may affect the nail, such as psoriasis or lichen planus. 5. Patients diagnosed with tinea pedis simultaneously clinically apparent . 6. Patients under current treatment with oral or topical antifungal drugs. 7. Hypersensitivity to any component of methyl aminolevulinate (MAL). 8. Porphyria (a contraindication to the use of MAL) 9. Allergy to almond oil or peanut (MAL excipients involved in contact allergy) |
1. Pacientes menores de 18 años. 2. Incapacidad o falta de voluntad de la persona física o jurídica/representante para dar el consentimiento informado por escrito. 3. Mujeres embarazadas o que piensen que puedan estarlo, o durante la lactancia. Las mujeres en edad fértil deben utilizar un método anticonceptivo durante la fase de tratamiento del ensayo clínico (desde el inicio hasta un mes después de la última sesión de TFD) para poder entrar en el ensayo. 4. Pacientes con enfermedades que puedan afectar a la uña, como la psoriasis o liquen plano. 5. Pacientes diagnosticados simultáneamente con tinea pedis clínicamente manifiesta (en los que sin tratamiento sistémico parece muy poco probable la curación de la onicomicosis, y no es aceptable el placebo). 6. Pacientes bajo tratamiento actual con fármacos antimicóticos orales o tópicos. 7. Hipersensibilidad a cualquier componente del metil aminolevulinato (MAL). 8. Porfiria (contraindica el empleo de MAL) 9. Alergia a los aceites de almendra o de cacahuete (excipientes del MAL implicados en alergia de contacto) |
