Phase IIB Study of PHENOGENE-1A (Cromolyn) as an Adjuvant Therapy in Mild to Moderate ALS
EU CTIS ID: 2025-520688-42-00
What this study is testing
To evaluate the effects of PHENOGENE-1A (cromolyn) on functional changes in subjects with mild to moderate stage ALS disease, by using the ALSFRS-R to measure changes in the score, over a 24-week treatment period.
- Therapeutic exploratory (Phase II)
A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Diagnosis of ALS; subjects must have a diagnosis of ALS according to the revised El Escorial Criteria as follows: a) Evidence of lower motor neuron (LMN) degeneration by clinical, electrophysiological, or neuropathological examination. b) Evidence of upper motor neuron (UMN) degeneration by clinical examination. c) Progressive spread of symptoms or signs within a region or to other regions, as determined by clinical examination or the history of disease progression. d) Absence of electrophysiological, neuroimaging, or pathological evidence of other diseases that might explain the UMN or LMN degeneration and exclusion of other causes.
- PIFR ≥100 L/minute.
- Must be receiving a stable dose of standard-of-care treatment, Riluzole for 4-weeks before signing informed consent.
- Female subjects who are of childbearing potential must agree to use of highly effective methods of contraception consistent with local regulations during the study, and for 3 months after the study drug administration. Examples include the following, but not limited to: a) Combined (estrogen and progestogen containing) or progestogen-only hormonal contraceptives; b) Intrauterine device or intrauterine hormone-releasing system; OR c) Post-menopausal status must have experienced their last menstrual period minimum of 1 year prior to study drug administration; OR d) Surgically sterilized. Female subject should be willing to not donate egg during the trial and for 3 months after the last dose of the study drug.
- Male subjects who are sexually active with a female of childbearing potential must agree to use highly effective contraception as described above, or a combination of 2 acceptable methods of contraception (e.g., a barrier method along with a female partner using a hormonal contraceptive method), in accordance with local regulations, throughout the duration of the study, and for 3 months after the last dose of the study drug. Male subject should be willing to not donate sperm during the trial and for 3 months after the last dose of the study drug.
- Male or female subjects aged 18 to 75 years inclusive.
You likely can't join if
- ALSFRS-R score change (decrease) by 2.5 or more points between the Screening and Day 1 (baseline) score.
- Taking inhaled protein products on a chronic basis (such as insulin, parathyroid hormone [PTH], etc).
- Subjects with a body weight of 32 kg or less, or a body mass index (BMI) of <17.5 or >35.0 at time of screening.
- Moderate-to-severe liver disease: aspartate aminotransferase (AST), alanine aminotransferase (ALT) >3 times the upper limit of normal; total bilirubin >1.5 x ULN ; subjects with hepatic diseases such as hepatic cirrhosis, hepatic cancer and active hepatitis.
- Moderate-to-severe renal disease: creatinine clearance <45 mL/min/1.73 m2 (by Cockcroft- Gault calculation).
- Any CS disorder or laboratory abnormality that, in the Investigator's opinion, could interfere with the subject's participation in the study, place the subject at increased risk, or confound interpretation of the study results
