Thank you, Kabir. The Lykos advisory committee was certainly eventful and it provided some key insights into the FDA's thinking and their requirements for review of therapeutics in this new class of drugs. Three items came into focus: the therapy aspect of the clinical protocol, the issue of unblinding and lack of certain safety data that FDA deemed important to understand. Let me discuss these in order. First, regarding psychotherapy, MDMA appears to increase interactive communication with the therapists during the drug experience. It truly is psychotherapy catalyzed by the drug. This is in contrast with psilocybin, which elicits a subjective inward experience for patients. With COMP360, the patient is supported by a licensed therapist or other medical professionals, mostly for safety purposes. There is no active psychotherapy on the day of drug administration. Most of the administration session is silent, and any interaction is typically to redirect the patient's focus back inwards. The pre-administration preparation ensures patients understand the trial and what to expect on the day of administration, and prepare them to be in the right frame of mind to undergo treatment, not unlike other medical procedures. Patients have two post-administration sessions to provide them with an opportunity to discuss their experience and integrate it into their lives. Second, turning to a discussion of unblinding, context is important here. It is not uncommon in neuroscience for drugs to produce effects that are detectable by patients. It is the absence of such effects that unblinds the patients in trials that are psychedelic. It is the presence of adverse effects, like nausea or somnolence, that are likely to cue the unblinding that may often occur in other trials, for example, of conventional antidepressants or antipsychotic drugs. Such unblinding has not prevented their approval as medicines. As requested by the FDA, our 005 trial is placebo controlled, which will help to characterize a safety baseline, but lack of an active control will make potential unblinding likely. By contrast, our 006 trial was designed similar to the Phase 2b, with a strategy to minimize the potential for unblinding. 006 has three active arms so patients know that they will receive a dose of COMP360, making it more difficult for them to discriminate, in particular, between the 10 and 25 milligram doses. In fact, most participants in the Phase 2b study reported an intensity of psychedelic effects that could have come from any of the doses. In addition, we have also put a cap of 15% on recruitment of patients with prior experience with psychedelic drugs. We believe that this design safeguards the blinding of the trial, and the two Phase 2 trials together will produce a robust package for the FDA. Finally, we are conducting the COMP360 TRD clinical program to the highest standards and we are collecting the range of safety data that would be expected of any pharmaceutical clinical development program, including positive side effect data. For example, we have collected data from the altered states of consciousness questionnaire after every drug administration. This survey is comprised of 94 items covering the full gamut of experiences, both positive and negative, attributable to psychedelic drugs. Looking at the FDA's guidelines and observing the discussion at the Lykos meeting, we are confident that our pivotal program will deliver what the FDA requires to effectively evaluate COMP360 treatment. Let me now hand the call to Teri for the financial overview.
