Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment was assured by keeping the randomization list and the drug codes locked in sealed opaque envelopes till the end of the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
consecutive patients presenting to the OPD with eligibility criteria had been asked to sign informed consent and randomized through software generated block randomization to either one of two similar capsules in similar packs
Masking / blinding
Blinded (masking used)

Brief summary
Spirulina platensis, a cynobacterium used frequently as a dietary supplement had been found to exhibit many immune-stimulating and antiviral activities. It had been found to activate macrophages, NK cells, T cells, B cells, and to stimulate the production of Interferon gamma and other cytokines. Natural substances isolated from Spirulina platensis had been found to be a potent inhibitor against several enveloped viruses by blocking viral absorption/penetration and some virus replication stages after penetration into cells.
We aimed to study whether this dietary supplement possesses any therapeutically feasible activity worthy of further larger controlled clinical evaluation, and is there any place to use it in the management of hepatitis C virus infection.
