Active clinical trials for "Pachyonychia Congenita"

In this phase 1 open label study, up to 10 eligible patients with type I punctate palmoplantar keratoderma or pachyonychia congenital will be recruited to be treated twice daily, for 12 weeks, with 1% topical KM-001. Treatment safety and efficacy will be assessed in the clinic on Days 7, 28, 42, 63and 84 after initiation of treatment. In between visits, safety will also be assessed by phone on Days 14, 21, 35, 49, 56, 70 and 77 of treatment. At the in-clinic visits, treatment efficacy (lesion clearance - IGA) will also be assessed. PK blood samples will be collected on Days 0, 7, 84 and One week after the end of treatment (EoT) visit, patients will return to the clinic for final safety, efficacy and PK evaluations.

This study evaluates the safety and efficacy of QTORIN 3.9% rapamycin anhydrous gel in the treatment of adults with Pachyonychia Congenita. This study includes a screening period, baseline period and 6-month treatment period.

This Phase 1b, open-label, single-center, prospective trial will be assessing the safety, tolerability, and efficacy of topical KM-001 1% in patients with PPPK1 or PC diseases. Patients will be provided jars of 30 g KM-001 1% and instructed to apply the cream twice daily on the plantar surfaces, for 84 consecutive days. Safety (AEs, blood work [at specific visits], vital signs), tolerability, and efficacy parameters (overall lesion improvement) will be assessed during in-clinic visits (Days 1 [enrolment], 7, 28, 42, 63, 84 [EoT], 112 [follow-up]). Safety and treatment compliance assessment will be done by phone calls on Days 14, 49, 70, and 98 (follow-up). PK samples will be collected to assess plasma levels of KM-001 on Screening, Day 112 & ET: any time during the visit. Day 7 and Day 84 (EoT), at 1 h, 2 h, 3 h, 6 h (+15 min) post-dose. Days 28 and 42 visit: 1 sample after the first dose, before the second dose, as late as possible in the visit. The patient will complete a patient-reported diary, consisting of treatment compliance and self-assessments for efficacy. Follow up- 2 weeks after EoT by phone call, and 4 weeks after EoT in clinic visit.

PALV-08 is a multicenter, open-label treatment (OLT) study enrolling adults with Pachyonychia Congenita (PC) with genotyped keratin mutations KRT6A, KRT6B, KRT6C or KRT16 who were previously enrolled in the PALV-05 (VAPAUS) trial. The purpose of this OLT study is to investigate the safety of long term exposure and pharmacokinetics (PK) of QTORIN rapamycin 3.9% anhydrous gel or "PTX-022".

VALO-2 is a multicenter, open-label extension (OLE) study enrolling patients with genotyped keratin mutations KRT6A, KRT6B and KRT16 who were previously treated with investigational PTX-022 during the VALO study. The purpose of the OLE study is to investigate long term exposure to investigational PTX-022 and evaluate safety and efficacy data. A sub-study is included to evaluate safety and efficacy of patients with genotyped keratin mutations of KRT6C and KRT17 not previously treated with investigational PTX-022.

International Pachyonychia Congenita Research Registry (IPCRR) is a patient registry for those suffering from Pachyonychia Congenita (PC). PC is an ultra-rare extremely painful skin disorder that causes painful blisters and callus on feet and sometimes hands, thickened nails, cysts and other features. The IPCRR consists of a questionnaire, patient photos, optional physician notes from telephone consultation to validate questionnaire and free genetic testing.

A study to evaluate safety and efficacy of topical sirolimus to treat plantar keratoderma in adults with PC. Subjects may receive either placebo or treatment with at least 1 foot receiving topical sirolimus at some time. For certain phases of the study treatment assignment to the right and left foot will be randomized in a double blind fashion. Blood levels will test systemic absorption of sirolimus. Other safety and efficacy measures will be taken through the 39-week study duration. Funding Source - FDA OOPD

Pachyonychia congenita (PC) is a rare, autosomal dominant keratin disorder affecting the nails, skin, oral mucosae, larynx, hair and teeth. Pathogenic mutations in keratin K6a, K6b, K16 or K17 act via a dominant negative mechanism, leading to manifestations of the disease. The most disabling PC symptom is a painful plantar blistering and keratoderma that requires use of ambulation devices in more than 50 percent of patients. Despite our understanding of the molecular basis of PC, current treatment is limited to mechanical removal of the thick calluses, non-specific topical keratolytics, and oral retinoids, none of which alleviates blistering or plantar pain satisfactorily. A public charity, PC Project, has been founded to support the development of treatments for PC (www.pachyonychia.org). In collaboration with this charity, a small company, TransDerm, Inc., has developed a small interfering RNA (siRNA) that specifically targets a mutation in one of the PC keratins, K6a. As this siRNA targets a single nucleotide mutation, it will only be effective against PC subjects harboring this specific mutation. There are currently only six known patients who carry this mutation in the International Pachyonychia Congenita Research Registry, but three of these patients live in Salt Lake City (a mother and two of her children). We propose to perform a Phase Ib clinical trial to test the safety and tolerability of TD101 in PC patients carrying an N171K mutation. We will complete treatment of the adult patient prior to recruitment of the minors.

Adult participants will apply a broccoli sprout extract-jojoba oil compound to one arm every night under occlusion for 1 week. Jojoba oil alone will be applied to the other arm. At the end of 1 week, a 6mm punch biopsy will be taken from both arms and analyzed via polymerase chain reaction (PCR) and immunohistochemistry for differences in various skin proteins.

This study evaluates the safety and efficacy of PTX-022, topical rapamycin, in the treatment of adults with moderate to severe Pachyonychia Congenita. This study includes four-parts, and if a participant completes all parts, the participant will have received at least 3-months of PTX-022 treatment.
