简介

A type of neurofibroma manifesting as a diffuse overgrowth of subcutaneous tissue, usually involving the face, scalp, neck, and chest but occasionally occurring in the abdomen or pelvis. The tumors tend to progress, and may extend along nerve roots to eventually involve the spinal roots and spinal cord. This process is almost always a manifestation of NEUROFIBROMATOSIS 1.

NCT06188741 / Not yet recruiting临床2期IIT

Phase 2 Trial of Selumetinib for the Prevention of Plexiform Neurofibroma Growth and Morbidity in Neurofibromatosis Type 1

Plexiform neurofibromas (PN) are known to cause significant morbidity in children with NF1. The recent FDA approval for selumetinib in children 2 years and older with inoperable symptomatic PN was based on the finding that selumetinib shrinks the majority of PN in children with NF1 and results in clinically meaningful benefit such as improvement in pain or range of motion. However, many morbidities, such as blindness or nerve damage, cannot be fully reversed with PN shrinkage. Therefore, there remains a critical need in this patient population to determine if young participants with PN in high-risk locations may benefit from early medical intervention prior to the development of clinical problems. This study will determine whether participants with asymptomatic PN in high-risk locations can potentially benefit from early treatment with selumetinib.

Observational Study of the Effectiveness and Safety of the MEK 1/2 Inhibitor (MEKi) Koselugo (Selumetinib) in Pediatric Patients With Symptomatic, Inoperable, Neurofibromatosis Type 1 (NF1)-Associated Plexiform Neurofibromas (PN)

This is a prospective, multicenter, observational study of Chinese pediatric NF1-PN patients treated with selumetinib. The study will be conducted at approximately 12 centers in China and will include approximately 80-100 patients. Treatment centers that have PN diagnosis and/or selumetinib treatment experience will be targeted for recruitment. Patients/caregivers who are eligible and willing to participate will be enrolled into the study. Patients will start selumetinib treatment after enrollment. The study will have a 16-month enrollment period. Patients will be followed up until the end of a 24-month observation period after first dose of selumetinib, or patient death, lost to follow-up, withdrawal of consent, whichever occurs first. Patients will be followed within a 24-month period (starting after first dose received) in the study even if selumetinib is discontinued. The aims of this study are to expand understanding of disease characteristics and treatment pattern of NF1-PN in China in a real-world setting and to evaluate real-world effectiveness and safety of selumetinib for Chinese pediatric patients with NF1-PN.

Neurofibroma: Case Series with Clinical Features and Recommendations.

Article

作者: Nasreen Khatri ; Muhammad Liaquat Raza ; Atia Aijaz ; Recha Ramesh ; Naveed Gianchand ; Faisal Akhlaq Ali Khan

Neurofibroma is an autosomal benign disorder. It can be localized, diffuse or invasive like plexiform neurofibroma that involves the nerves, muscle, tissues, skeleton. It represents itself as a destructive variant of neurofibroma, mostly present as orbital or periorbital neurofibroma or may be associated with autosomal dominant disease. Clinical diagnosis of neurofibromatosis (NF) according to National Institutes of Health (NIH) criteria should have more than two of the seven features including lisch nodules, cafe'- au-lait spots, plexiform neurofibroma, optic glioma, freckling, first degree relative with NF or dysplasia of cortical bones. However, proper early diagnosis is still crucial due to its various presentation such as cheek mass, painless swelling on skin, chalazion, intratracheal tumor, genital swelling or ptosis. It is reported that neurofibroma often represents as ocular or facial swelling. Here we are presenting features of neurofibroma of eight cases of patients from Civil Hospital, Karachi. These cases had main complain of overhanging skin mass mainly on orbital or periorbital region that damage the area and with poor daily activities. Multiple nodules on face and body along with them Cafe'-au-lait spots and lisch nodules were main signs. While, other signs i.e. ptosis, pterygium, telecanthus and muddy discoloration of conjunctiva need further evaluation for correlation with neurofibromatosis. Debulking surgery was planned for most of the cases but the huge disfigurement caused by overhanging skin mass and nodules made it a challenge for plastic surgeons to provide good outcomes with minimum damage. Keywords: neurofibroma; lisch nodules; ptosis; Cafe'-au-lait spot; periorbital; overhanging skin.

Selumetinib for children with neurofibromatosis type 1 and plexiform neurofibromas: A plain language summary of SPRINT.

Review

作者: Andrea M Gross ; Colette Achée ; Sarah E Hart ; Lindsay Brewer ; Andrea Baldwin ; Pamela L Wolters ; Brigitte C Widemann ; SPRINT study team

WHAT IS THIS SUMMARY ABOUT?:

This summary describes a publication about a study called SPRINT. The SPRINT study included 50 children with neurofibromatosis type 1 (NF1) and plexiform neurofibroma (PN) that could not be removed with surgery. PNs are tumors that grow along nerves and can cause various problems for children, such as pain, changes to appearance, and muscle weakness. In SPRINT, the study team wanted to learn whether a medication called selumetinib was able to shrink the PN caused by NF1 (also known as NF1-related PN), and if shrinking PNs helped relieve children of the problems caused by it. To assess how selumetinib might help, children had scans to measure the size of their PN, completed questionnaires, and had a variety of other tests done by their doctor. Their caregivers also completed questionnaires about their child. The children took selumetinib capsules twice a day on an empty stomach.

WHAT WERE THE RESULTS?:

The results showed that selumetinib was able to shrink the PN for most children (68%). The results also showed that the problems caused by the children's PNs mostly improved while on selumetinib treatment. SPRINT also showed that the side effects of selumetinib were mainly mild and could be managed by doctors.

WHAT DO THE RESULTS MEAN?:

Before SPRINT, there were not many treatment options for children with NF1 and PN as there were no medications that had been shown to shrink PN, and surgery was not always possible. SPRINT showed that this medication shrinks most PNs and could help children with NF1 and PN. In April 2020, selumetinib was approved by the US Food and Drug Administration (FDA) because of the results of SPRINT. Selumetinib was the first and, as of February 2024, is the only medicine that can be prescribed by doctors to help children with NF1-related PN. Clinical Trial Registration: NCT01362803 (SPRINT) (ClinicalTrials.gov).

OBJECTIVES:

Neurofibromatosis type 1 (NF1) is a genetic cancer predisposition syndrome that can impact multiple organ systems and is associated with plexiform neurofibroma tumors, requiring care from birth through adulthood. Adolescents and young adults (AYAs) with NF1 face several barriers to transition from pediatric to adult care. This cross-sectional study aimed to assess transition readiness in this population and to evaluate relationships between specific NF1 symptoms and transition readiness.

METHODS:

AYAs (aged 16-24) enrolled in existing studies related to NF1 were eligible. AYAs and their parents completed measures of transition readiness (Transition Readiness Assessment Questionnaire version 4 [TRAQ-4]), and AYAs also completed a transition readiness interview (UNC TRxANSITION).

RESULTS:

Thirty-eight AYAs (mean age = 19.95 ± 2.68 years) participated in the study. Average TRAQ scores indicated that AYAs were still learning Self-Management skills (M = 3.37, SD = 1.08) and Self-Advocacy skills (M = 3.98, SD = 0.67). Older AYAs had higher TRAQ scores for Self-Management (r = 0.70, p < .001) and Self-Advocacy (r = 0.41, p = .011) than younger AYAs. Parents and AYAs had similar TRAQ scores. About one third of AYAs (37.8%, n = 14) expressed uncertainty about how NF1 might affect them in the future. The remaining AYAs mostly expressed concerns regarding tumor growth, pain, or cancer.

CONCLUSIONS:

In this small study, preliminary findings suggest that AYAs with NF1 express confidence in many areas of transition readiness but continue to require support, particularly with Self-Management skills. Given the gaps in understanding of future health risks, AYAs with NF1 would benefit from early assessment, psychoeducation, and support for transition readiness to adult care.

KeChow Pharma Announces NMPA Approval of Tunlametinib (HL-085) as the First Targeted Therapy for Patients with NRAS Mutated Advanced Melanoma and Previously Treated with PD-1/PD-L1

-- Tunlametinib is poised to be a potential best-in-class MEK inhibitor based on positive data from the pivotal Phase 2 study SHANGHAI, March 18, 2024 /PRNewswire/ -- KeChow Pharma, a commercial-stage pharmaceutical company focused on developing and commercializing differentiated small molecule therapeutics for cancer, today announced that the China National Medical Products Administration (NMPA) has approved tunlametinib (HL-085) for the treatment of patients with NRAS mutated advanced melanoma who were previously treated with PD-1/PD-L1. This is the first approved targeted therapy for this patient population and the first product originated from KeChow's in-house research and development activities since the company's inception. The new drug application (NDA) of tunlametinib was previously granted priority review by the Center for Drug Evaluation (CDE) of the NMPA. The approval was based on the results of a multicenter, single-arm, phase II, pivotal registrational study which conducted in 100 patients in China (NCT 05217303). Clinical efficacy data of tunlametinib in China, as assessed by independent radiological review committee (IRRC) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, include an overall response rate (ORR) of 35.8%, median progression free survival (PFS) of 4.2 months, and disease control rate (DCR) of 72.6%. Subgroup analysis showed that in patients who had previously received immunotherapy, the ORR was 40.6%. The most common treatment-related skin event was rash (53%), followed by dermatitis acneiform (24%). The most common grade ≥3 TRAE in this study was blood creatine phosphokinase increased (38.0%), which was mostly asymptomatic and manageable with dose modification [1]. "We are excited and proud of this major milestone for KeChow. Tunlametinib, approved in China, is the first internally designed and developed molecule by KeChow team ." said Dr. Hongqi Tian, Founder, Chief Executive Officer and Chairman of KeChow. "The approval of tunlametinib is an important milestone to provide new treatment option for Chinese patients with NRAS-mutated advanced melanoma who previously received PD-1/PD-L1. We would like to express our sincere gratitude to the clinicians and patients who participated in our trials, and we thank the health authorities for their strong support. We are committed to making tunlametinib available in China as soon as possible to serve this patient population." "We own the worldwide rights to tunlametinib. KeChow has a comprehensive clinical development plan to evaluate tunlametinib as a monotherapy and in combination with other standard of care therapies to treat multiple cancers including melanoma, neurofibromatosis type 1–related plexiform neurofibromas, colorectal cancer, and non-small cell lung cancer in China," said Dr. Hongqi Tian. "We look forward to expanding the product potential of tunlametinib through establishing partnerships on a worldwide basis." Melanoma is one of the most common cutaneous cancers. There are an estimated 20,000 newly diagnosed melanoma patients in China each year [2]. NRAS mutations accounted for 10.4~12.6% of melanoma patients in China [3], and 15-25% globally [4-7]. NRAS-mutated melanoma is more aggressive and associated with poorer outcomes [8-11]. There were no approved targeted therapies for patients with NRAS-mutant melanoma. Tunlametinib is the first small molecule drug approved for this indication. About tunlametinib Tunlametinib is a small molecule inhibitor of Mitogen-activated protein kinase kinase (MEK) discovered and developed by KeChow. Tunlametinib targets the Mitogen-activated protein kinase (MAPK)/extracellular regulated protein kinases (ERK) signaling pathway (also known as RAS/RAF/MEK/ERK signaling pathway) by inhibiting the activity of MEK kinase, blocking downstream signaling pathways, inhibiting the growth and proliferation of tumor cell. MAPK/ERK signaling pathway plays a critical role in cancer cell proliferation and apoptosis. Aberrant activation of this signaling pathway has been implicated in more than one-third of all malignancies. Compared to other approved MEK inhibitors, tunlametinib demonstrated stronger target inhibition and improved pharmacokinetic properties. About KeChow Pharma Shanghai KeChow Pharma, Inc. is a commercial-stage pharmaceutical company focusing on differentiated small molecule therapeutics for cancer. The company was founded by Dr. Hongqi Tian in 2014, and is headquartered in Shanghai Zhangjiang Pharmaceutical Valley. Since its inception, KeChow is committed to accelerate the discovery, development and commercialization of novel small molecule therapeutics through scientific innovation and by leveraging extensive pharmaceutical expertise from the management team. The company has a science driven corporate culture and is specialized in the development of best-in-class innovative therapeutics to address unmet medical needs of patients around the world.

China greenlights first targeted therapy for NRAS-mutated melanoma

Chinese biotech KeChow Pharma has secured approval from the country's drug regulator for tunlametinib (HL-085), an oral MEK inhibitor indicated for patients with NRAS-mutated advanced melanoma previously treated with PD-1/PD-L1 immune checkpoint inhibitors.The company noted Monday that its drug, developed entirely in-house by KeChow, becomes the first approved targeted therapy for this patient population. Melanoma harbouring NRAS mutations represents approximately 10-12% of melanoma patients in China and is characterised by more aggressive disease and poorer outcomes, it added.The approval was based on positive data from a pivotal single-arm Phase II study involving 100 patients in China. KeChow said the trial demonstrated an overall response rate (ORR) of 35.8%, with median progression-free survival of 4.2 months. In a subset of patients previously treated with immunotherapy, the ORR increased to 40.6%.Side effects include rash and dermatitis acneiform. The most common Grade ≥3 treatment-related adverse event was increased blood creatine phosphokinase, which occurred at a rate of 38%, and was mostly asymptomatic and manageable with dose modification, according to the company.KeChow owns worldwide rights to tunlametinib and has a clinical development plan evaluating it, both as a monotherapy and in combination regimens, across multiple cancer types such as melanoma, neurofibromatosis type 1–related plexiform neurofibromas, colorectal cancer, and non-small-cell lung cancer in China, CEO Hongqi Tian said.The company is also looking to expand the product by "establishing partnerships on a worldwide basis," the executive added.
