IB1001 Clinical Trials

IB1001 Clinical Trials

IntraBio is conducting three multinational clinical trials with its lead compound, IB1001 (N-acetyl-L-leucine) for the treatment of three orphan diseases: IB1001-201, Niemann-Pick disease type C (NPC); IB1001-202, GM2 Gangliosidosis (Tay-Sachs and Sandhoff); IB1001-203, Ataxia-Telangiectasia (A-T)

Trial Status

The IB1001-201 (NPC) clinical trial completed enrollment in January 2020. Topline results were was announced in September 2020 confirming the clinical trial demonstrated a statistically significant and clinically meaningful improvement in both the primary and topline secondary endpoints for the treatment of pediatric and adult patients with NPC.

The IB1001-202 (GM2) and IB1001-203 (A-T) clinical trials have been significantly impacted by the global outbreak of COVID-19. The IB1001-202 trial is on track to be completed in Q4 2020. Recruitment for the IB1001-203 is delayed, given respiratory diseases are characteristics of A-T. Enrollment will continue when it is safe for patients and clinical trial sites.

FREQUENTLY ASKED QUESTIONS

What are the IB1001 Clinical Studies?

IB1001-201 (NPC), IB1001-202 (GM2), and IB1001-203 (A-T) are three parallel studies that utilize a master protocol to investigate IB1001 for the treatment of three rare, serious, diseases: NPC, GM2, and A-T. They each have two treatment sequences: a “Parent Study” and an “Extension Phase”.

What is the goal of the IB1001 studies?

The goal of the Parent Study is to demonstrate that IB1001 is safe and effective at treating symptoms and improving functioning and quality of life in patients with NPC, GM2, and A-T. The goal of the Extension Phase is to demonstrate the neuroprotective, disease-modifying treatment effects of IB1001 for these disorders.

These assessments will be made based on the clinical outcomes measurements such as the 8 Meter Walk Test (8MWT) and 9 Hole Peg Test (9HPT), the Scale for Assessment and Rating of Ataxia (SARA), Clinical Global Impression (CGI) Scales (by Physicians, Caregivers, and Patients), and Quality of Life Questionnaires.

In addition, the studies aim to further characterize the safety and tolerability profile of IB1001 for the treatment of NPC, GM2, and A-T.

How long are the IB1001 studies?

Parent Study: Following a screening period which will last approximately 2 – 8 weeks, patients will take part in the studies for approximately 12 weeks (6-week treatment, 6-week washout).

Extension Phase: Following the Parent Study, patients will have the opportunity to continue into with treatment with IB1001 for 2 one-year treatment periods (separated by a 6-week washout).

How many patients will be enrolled?

Each study will recruit approximately 30 patients.

Will all patients receive treatment?

All patients enrolled in the trials will receive treatment with IB1001. There is no placebo arm.

 Where are the trial sites?

The trials will be conducted at key specialist centers to clearly establish the safety and efficacy of IB1001 for the treatment of these rare, life-threatening conditions.

Clinical trial sites are currently planned to be established in the United States, United Kingdom, Spain, Slovakia, and Germany. Clinical trial sites may vary for each specific study by country/location.

ClinicalTrials.Gov will be updated regularly with details on clinical trial centers for each study in each country.

Who is eligible to participate in the trials?

In Europe, patients ages 6 and older with a confirmed genetic diagnosis of Niemann-Pick disease Type C (NPC), GM2 Gangliosidosis (Tay-Sachs or Sandhoff Disease), or Ataxia-Telangiectasia (A-T) may be accepted to participate in the trials provided they meet the eligibility criteria as determined by the doctors involved in the trials.

In the United States, patients ages 18 and older with a confirmed genetic diagnosis of Niemann-Pick disease Type C (NPC), GM2 Gangliosidosis (Tay-Sachs or Sandhoff Disease), or Ataxia-Telangiectasia (A-T) may be accepted to participate in the trials provided they meet the eligibility criteria as determined by the doctors involved in the trials.

The full eligibility criteria for the studies can be found at ClinicalTrials.Gov

Why are the eligibility requirements different in the US and Europe?

The eligibility requirements vary according to each national regulatory requirements, and the informed assessment of each national agency responsible for approving the clinical trials.

Who will be selecting the participants?

The Principal Investigator at each clinical site is responsible for determining if a patient is eligible to participate in the clinical trial.

Will patients have to cover the costs to travel to participate in the trial?

Patients will be reimbursed for reasonable out-of-pocket expenses, such as travel expenses that will be incurred for participating in the trial.

When will the trials start?

Enrollment in the IB1001-202 and IB1001-203 studies is ongoing.
