He is also Senior Vice President at SSI Strategy and a member of its Global Regulatory Leadership Team. Trevor earned his Pharmacy degree (BSc Hons) from Portsmouth University.
Head of Program Management
Tom McMonagle is an Engagement Manager at SSI Strategy. At Repeat Therapeutics, he leads program management, driving cross-functional execution across clinical, regulatory, and operational workstreams. He brings experience from large pharmaceutical organizations and early-stage biotechs, helping programs move efficiently from discovery toward clinical development. He has supported global regulatory submissions, rare-disease clinical programs, and organizational transformation initiatives across the life sciences industry, known for aligning technical and executive stakeholders to deliver on key milestones. Tom holds a BA in Biology from the University of Pennsylvania.
Head of Clinical Operations
Brendan Slagle brings over 18 years of clinical research and operational leadership experience across the pharmaceutical and medical device industries. Brendan is Senior Director at SSI Strategy. In his role at Repeat Therapeutics, he oversees clinical operations and development strategy, ensuring programs advance efficiently and with patient safety at the center. Before joining SSI, Brendan held roles at Halloran Consulting Group, Medtronic, and Dartmouth’s Norris Cotton Cancer Center, supporting early-stage life science companies in designing and executing clinical programs. Brendan holds an ALM in Biotechnology from Harvard University and a BS in Clinical Psychology from the University of North Dakota.
Head of Clinical Development
Nino Devidze, PhD, brings over 25 years of experience in neuroscience and drug development. Nino is a Senior Vice President at SSI Strategy. In her role at Repeat Therapeutics, sheleads early clinical strategy and execution. Her prior roles span Bristol-Myers Squibb, Spark Therapeutics, Forma Therapeutics, the University of Pennsylvania, and Redpin Therapeutics, advancing therapies across neurodegenerative and neuromuscular diseases.
She holds a PhD in Neuroscience from the Beritashvili Institute in Tbilisi, Republic of Georgia, and completed her postdoctoral training at The Rockefeller University.

Repeat expansion diseases develop when small stretches of DNA are mistakenly copied too many times, disrupting how cells function. These genetic changes can affect different parts of the central nervous system, leading to a range of serious neurodegenerative disorders.

ALS, the most common type of MND (motor neuron disease), progressively damages the nerve cells in the brain and spinal cord that power every voluntary movement, from lifting a glass of water to taking a breath. Over time, these cells lose their ability to send signals to muscles, leading to weakness, loss of function, and, eventually, paralysis.
While most people with ALS have no family history, a smaller group carries a genetic change that raises their risk.
C9orf72 is the most common genetic cause of ALS. People living with C9orf72-ALS often face faster progression and fewer answers. They have waited years for new options. We are working toward answers that may open the door to progress for the wider ALS community.
The C9orf72 mutation disrupts an essential metabolic pathway. Without it, nerve cells cannot make and recycle molecules they need to function and survive. Our approach is focused on restoring these essential molecules, thereby protecting nerve cells from damage and loss.
Designed To Work With The Body’s Own Biochemistry
Our investigational therapies, RTX-101 and RTX-111, are oral combinations being evaluated in a clinical study in Australia to assess safety and tolerability. They are built on a scientific approach that leverages decades of metabolic signaling and neurodegeneration research to target the underlying biology of ALS.
Where we are today:
Reach
Pursuing access and affordability as essential outcomes.
Restore
Renewing balance and cellular health through metabolic science.
Redefine
Shaping a new era of understanding and treatment for ALS and beyond.
Every patient deserves access to science that puts them first. At Repeat Therapeutics, our work is about restoring hope and redefining what is possible in the fight against repeat expansion diseases. We are dedicated to developing an effective therapeutic option for ALS and other neurodegenerative diseases to improve the quality of life for patients in need.
Nobel laureate Dr. Katalin Karikó and two-time Olympic gold medalist Susan Francia, who bring extraordinary vision and resilience to the treatment and prevention of neurodegenerative diseases.
