Please respond to this letter by providing the requested information and either submitting an amended draft registration statement or publicly filing your registration statement on EDGAR.

Given that FDA approval of your products for the treatment of your stated indications is not within your control, it is inappropriate to predict the earliest date that such approval may be obtained for all of your products aside from Arakoda, which has been approved by the FDA only for the prevention of malaria. As requested by our prior comment, please also depict the phase or status of development for each product candidate including separate columns for preclinical development, Phase 1, Phase 2 and Phase 3 trials with arrows showing where each program has progressed.
