AB - ota-carrageenan (I-C) is active against respiratory viruses in vitro and was effective as nasal spray in three previousclinical trials. The current trial served to further investigate I-C in patients with early common cold symptoms.Methods: This randomized, placebo-controlled, double-blind phase IV trial was conducted in 200 adult patientswith self-diagnosed colds of <48 h’ duration that were confirmed by baseline cold symptom scores. Patients wereto self-administer 0.12 % I-C or placebo spray (NaCl 0.5 %) four times daily for four to ten days and record symptominformation for ten days. Common respiratory viruses were quantified by RT-PCR during pretreatment and on Day 3or 4. The primary endpoint was the mean total symptom score (TSS) of eight cold symptoms on Days 2–4 (TSS2–4).Results: Patients in both treatment groups had similar baseline TSSs (mean TSS: 6.75 for I-C and 6.79 for placebo).Viruses were detected in baseline samples from 53 of 98 I-C patients (54.1 %) and 54 of 97 placebo patients(55.7 %). Mean ± SE for TSS2–4 was 5.78 ± 0.25 for I-C patients and 6.39 ± 0.25 for placebo (p = 0.0895). Exploratoryanalyses after unblinding (TSS2–4 excluding a patient with aberrantly high symptom scores [TSS2–4, ex 1pt]; mean ofTSS over Days 1–4 [TSS1–4]; change in TSS1–4 relative to baseline [TSS1–4, rel]) demonstrated treatment differences infavor of I-C (p = 0.0364, p = 0.0495 and p = 0.0421, respectively). For patients with quantifiable rhinovirus/enterovirusat baseline, there was a trend towards greater reduction of virus load at Day 3 or 4 (p = 0.0958; I-C: 90.2 %reduction in viral load; placebo: 72.0 %). Treatments were well tolerated with no differences in adverse event rates.Conclusions: The primary endpoint did not demonstrate a statistically significant difference between I-C andplacebo but showed a trend towards I-C benefit. Exploratory analyses indicated significant reduction
