EspeRare is deeply honoured to receive the 2026 Philanthropy Partnership Award from the US-based National Foundation for Ectodermal Dysplasias (NFED). 

This recognition is particularly meaningful as it comes from an organisation that directly support the families affected by X-linked hypohidrotic ectodermal dysplasia (XLHED), a community that has been central to the ER-004 journey. 

When EspeRare stepped in to rescue ER-004 and bring it back into active development, NFED became a key partner in shaping a patient-centred development pathway. Together, we have worked to ensure that the perspectives of patients and families are meaningfully embedded throughout clinical development. 

Developing a potential therapy for a rare disease is a long and demanding journey. It brings moments of hope and scientific progress, but also challenges, uncertainty, and the need for sustained collaboration. Throughout this journey, NFED’s openness, trust, and continued engagement have helped shape the programme in a meaningful way. 

Although the award is presented to EspeRare, this recognition also reflects the broader efforts of the XLHED community. We extend our deepest thanks to NFED, to the patient representatives and community members whose perspectives have helped inform this work, to the investigators, and to everyone who has contributed to this collective effort. We are also pleased to recognise Pierre Fabre Laboratories, EspeRare’s partner for the co-development and commercialisation of ER-004, as part of this shared journey. 

EspeRare is grateful for this recognition and for NFED’s partnership. It is a powerful reminder that meaningful therapeutic innovation begins by listening to patient communities and their representatives.

EspecRare is pleased to announce its collaboration with Twinkle, an association founded in France, around a common goal: to better support children and their families facing the end of life through the Twinkle Box project, a toolkit designed for pediatric palliative care teams.

At the heart of the Twinkle Box are three children's books written by Ewen and Michaela Sedman.

The first two address environmental issues such as light pollution and melting glaciers. The third, “Alphi and the Star Factory,” features the same characters to open up a secular and accessible dialogue about the afterlife, based on scientific concepts related to molecules, energy, and the laws of physics. This stories’ progression allows children to become familiar with the characters before tackling more sensitive topics around the end of life.

The kit was designed in close collaboration with Swiss, French, and German psychologists to support children and their loved ones during end-of-life care and the grieving process.

Through this project, EspeRare and Twinkle aim to equip healthcare teams with practicaltailored tools to support children and their families with kindness, respect, and compassion.

The TwinkleBox is available in French, German, and English, and is distributed free of charge to paediatric palliative care providers in Switzerland and internationally. 

This partnership is another example of EspeRare’s mission-driven commitment to deliver tangible human impact, closely aligned with the needs of patients, families, and caregivers.

EspeRare and the n-Lorem Foundation have launched a strategic partnership to bring individualized antisense oligonucleotide (ASO) therapies to patients with nano-rare genetic conditions in Europe.

The collaboration will begin with a pilot phase in Switzerland, aimed at unlocking the regulatory, diagnostic, and clinical pathways needed to enable access to these transformative treatments. Initial efforts will focus on a small group of carefully selected Swiss patients already matched to individualized ASO therapies developed by n-Lorem and authorized for use by the FDA in the United States.

“We are thrilled to have Dr. Ryan Taft leading this initiative for EspeRare,” said Caroline Kant, Executive Director and Co-founder of the EspeRare Foundation. “His deep understanding of genomic medicine and experience at the intersection of science, regulation, and patient access are central to our efforts to responsibly expand this new therapeutic paradigm in Europe. We are equally grateful to Lifehouse, whose commitment to advancing care for children affected by severe rare neurodevelopmental disorders is instrumental in enabling this work.”

n-Lorem has pioneered a groundbreaking model in precision medicine by designing and providing individualized ASO therapies for patients with nano-rare genetic conditions—typically affecting only a handful of individuals worldwide. While these therapies are currently developed and accessible exclusively in the United States, the collaboration with EspeRare aims to explore how similar therapeutic pathways could be enabled in Europe, through careful adaptation to the specific regulatory, ethical, and clinical frameworks of both the Swiss and the European context.

EspeRare brings over a decade of experience navigating complex regulatory environments and collaborating with academic hospitals, ethics committees, and public authorities. In this collaboration, EspeRare’s role is to facilitate regulatory coordination, engage key stakeholders, and help develop sustainable access pathways, while clinical oversight and patient care will remain entrusted to accredited medical institutions.

“This program is focused on expanding access to cutting-edge therapies, and improving rare disease patient lives as quickly as possible,” said Dr. Taft. “Together with n-Lorem, we’re building the bridge between its individualized ASO platform, and the systems required to deliver these treatments to patients outside the United States.”

This initiative is supported by Lifehouse, whose commitment to advancing care for children affected by severe rare neurodevelopmental disorders has been instrumental in enabling this work.

This collaboration reflects EspeRare’s broader mission to bridge scientific innovation and equitable access for overlooked patient populations, while ensuring that new therapeutic paradigms and precision medicine are introduced responsibly and sustainably.

The EspeRare Foundation is pleased to announce the publication of its article “Prenatal therapies: a Points to Consider framework for responsible innovation” in BMC Medical Genomics. This work, co-authored by McGill scholars Eric M. Meslin & Bartha Maria Knoppers, and by EspeRare’s Caroline Kant & Sebastien Mazzuri, introduces the first international framework dedicated to the ethical, legal, and governance dimensions of developing and applying innovative prenatal therapies.

Prenatal therapies represent a transformative frontier in medicine, enabling medical interventions before birth to prevent or mitigate severe congenital conditions. As these interventions rapidly progress from experimental research toward clinical implementation, they raise novel and complex questions, including around maternal–fetal risk, consent, regulatory oversight, and equitable access.

To address these challenges, the authors developed a comprehensive “Points to Consider” (P2C) framework. The P2C identifies nine key ethical and governance domains, ranging from maternal & fetal well-being, future-proof risk–benefit assessment, and responsible science & clinical care, to patient & public engagement, funding sustainability, public health integration, and international collaboration. Together, these points provide a structured reference to guide responsible innovation across the entire research-to-clinic continuum.

“Prenatal therapies are redefining the boundaries of prevention and care,” said Dr. Sebastien Mazzuri, Director of Innovation, Research, and Bioethics at EspeRare. “This framework is an invitation for researchers, clinicians, regulators, and policymakers to work together in ensuring these scientific advances are pursued ethically, inclusively, and for the benefit of future generations.”

The P2C was developed through an international, multidisciplinary collaboration engaging leading experts in bioethics, human rights, and regulatory science. It aims to serve as a practical tool to promote shared understanding, stakeholder dialogue, and ethical accountability as prenatal therapies move toward broader clinical application.

EspeRare will now look to activate the framework through further consultation and stakeholder engagement, working with patient communities, professional societies, and regulatory partners to translate its principles into actionable recommendations and best practices for real-world adoption.
