New hope for ALS patients: experimental drug IFB-088 tested in trial
NCT ID NCT05508074
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tested whether adding IFB-088 to standard riluzole treatment is safe and effective for people with bulbar-onset ALS (a form that first affects speech and swallowing). 51 participants received either IFB-088 plus riluzole or a placebo plus riluzole for 6 months. Researchers measured disease progression using functional scales and monitored side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- IFB-088 (also called Icerguastat) plus riluzole
- What this could lead to
- If it works, this could point toward a new treatment option for people with bulbar-onset ALS, potentially slowing disease progression.
- What could go wrong
- This is an early exploratory trial with only 51 participants, so results may not be conclusive. The drug may show no benefit or cause side effects.

Inclusion Criteria: 1. Diagnosis of probable or definite ALS according to the revised El Escorial criteria \[29\], with bulbar onset of disease, familial or sporadic form, 2. Onset of symptoms ≤ 18 months prior to screening, as reported by the patient, 3. Adult males or females, aged at least 18 years old, 4. SVC \> 60% of predicted value for age and sex, 5. ALSFRS-R score ≥ 36, 6. Treatment with riluzole 100 mg/day, at stable dose since at least one month and well tolerated, 7. Male or female patient of childbearing potential10 who agrees to use highly effective mechanical contraception methods (sexual abstinence, intrauterine device, bilateral tubal occlusion, vasectomised partner) throughout the study, and for 3 months after the end of the treatment, 8. Patient who read, understood and signed the ICF, 9. Patient who is willing to adhere to the study visit schedule and is capable to understand and comply with protocol requirements. Exclusion Criteria: 1. Known other significant neurological disease(s), 2. Serious illness(es) or medical condition(s) (e.g. unstable cardiac disease, cancer, hematologic disease, hepatitis or liver failure, renal failure) that is not stabilised or that could require hospitalisation and may jeopardise the participation in the study, 3. Abnormal renal function at screening defined as estimated glomerular filtration rate (eGFR) \< 60 mL/min/1.73m2, 4. Abnormal liver function at screening defined as total bilirubin levels \>1.5 ULN, and/or AST and/or ALT \>3 ULN, 5. Neutropenia (ANC \<1.5 x 109/L) at screening, 6. Other causes of neuromuscular weakness, 7. Non progressive or very rapidly progressing ALS (ALSFRS-R decline from disease onset to randomisation ≤ 0.1 / month or ≥ 1.2 / month)11, 8. Non-invasive ventilation, 9. Tracheotomy, 10. Weight loss ≥ 10% compared to weight at symptoms onset as declared by the patient or BMI \<18 kg/m2 at screening, 11. Dementia or other severe active psychiatric illness, including suicidal ideation assessed using the Columbia-Suicide Severity Rating Scale (C-SSRS), 12. Patient with a significant pulmonary disorder not attributed to ALS or who require treatments that might complicate the evaluation of the effect of ALS on respiratory function, 13. Patient treated by edaravone for ALS, 14. Patient using unauthorised concomitant treatments, namely moderate or strong inhibitors or inducers of CYP1A2, strong inhibitors or inducers of CYP2D6 or 2C19 and strong inhibitors of OCT2, as listed in Section 6.2. Combined oral contraceptives containing ethinylestradiol are forbidden concomitant medications, 15. Smoker of \> 10 cigarettes per day (e-cigarettes and nicotine patches are permitted), 16. Known hypersensitivity to any of the ingredients or excipients of the IMPs, 17. Pregnant, lactating women, 18. Patient who participated in another trial of investigational drug(s) within 30 days prior to randomisation, or 5 half-lives of the previous investigational product, whichever is longer, 19. Patient who has forfeited their freedom by administrative or legal award, or who is under guardianship or under limited judicial protection.
