Thanks Andrew. As we announced in today's press release, during the quarter, we received final approval from the World Health Organization and the United States Adopted Name Council for Aficamten to be used as the International Nonproprietary Name, or CK-3773274. About three weeks ago, we announced a positive top line results from cohorts 1 and 2 of REDWOOD-HCM, the Phase 2 clinical trial of Aficamten. Since we held a dedicated conference call to report the results, I'm not going to go into detail but rather recap the key data and focus on next steps toward opening a Phase 3 clinical trial by the end of this year. Top line results from REDWOOD-HCM demonstrated that treatment with Aficamten for 10 weeks resulted in highly statistically significant reductions from baseline compared to placebo, and the average resting and post-valsalva left ventricular outflow tract pressure gradients in both cohorts 1 and 2o. In Cohort 1, which evaluated a lower dose range of five to 10 milligrams, 79% of patients treated with Aficamten achieved the target goals of treatment, defined as resting gradient less than 30 millimeters of mercury and post-valsalva gradient less than 50 millimeters of mercury at week 10 compared to 8% for placebo. In Cohort 2 with studied a higher dose range of 10 to 30 milligrams, 93% of patients treated with Aficamten achieved the target goal. Patients treated with Aficamten experienced decreases in both resting and post-valsalva gradients by week two, and a maximum treatment effects was achieved by week six after completion of dose titration, which was the same for the final visit week at 10. Treatment with Aficamten was generally well tolerated. The incidence of adverse events was similar between treatment arms. No serious adverse events were attributed to Aficamten. And no treatment interruptions occurred on drug treatment. Importantly, we were pleased to see that only one patient experienced a transient decreased in left ventricular ejection fraction less than 50%, which required a dose adjustment, but did not result in dose interruption. Overall, feedback from the investigators of the trial has been quite positive and enthusiastic, given the magnitude of the treatment effect, the proportion of patients who achieved response criteria and the overall safety and tolerability profile observed. In the quarter, we initiated the open label extension trial of REDWOOD-HCM, which continues to enroll patients from Cohort 1 and is now enrolling patients with Cohort 2. The primary objective of this trial is the evaluation of long term safety of Aficamten. And the secondary objectives focus on the evaluation of gradient reduction and pharmacokinetics with long-term administration of Aficamten. We're also conducting a cardiac MRI sub study to assess changes in cardiac morphology, function and fibrosis. Patients in the open label extension will begin at the lowest dose of five milligrams and will be individually titrated to achieve target gradients, as informed by cohorts 1 and 2. As a reminder, we still have cohort three in REDWOOD-HCM ongoing, which includes patients treated with Aficamten who are also on dicey pyramide as background therapy. This cohort will further inform the inclusion of this small but important patient population in Phase 3. We are moving rapidly begin our Phase 3 clinical trial of Aficamten in patients with obstructive HCM in the fourth quarter, continuing preparations that began last December when we obtain results of the cohort 1 interim analysis from REDWOOD-HCM. During the second quarter, we had a Type C meeting with the FDA to review our plan for the Phase 3 trial. In that meeting, we reviewed the design endpoints and patient populations, and found the feedback we received enabling of our plans to advance to Phase 3. Building on this informative Type C meeting, we recently received FDA feedback from our end of Phase 2 meeting. After review of the final doses selected for Phase 3, namely 5, 10, 15 and 20 milligrams. And our proposal to continue individualize echocardiogram guided dosing. The agency agreed with our dose titration strategy. We also received helpful feedback on other aspects of the overall development program, including non clinical safety, clinical pharmacology, and the preferred format for datasets among other components. In addition, we initiated interactions with EMA during the quarter and received feedback and informed our proposed Phase 3 clinical trial design. We anticipate additional engagements this quarter from HTS to further inform our strategy for this program in Europe. Moreover, under our collaboration with ji Xing pharmaceuticals, during the second quarter, ji Xing continued enrolling patients in a Phase 1study of Aficamten in China and prepare for participation in the Phase 3 clinical trial of Aficamten in obstructive HCM. As we finalize preparations for our Phase 3 trial and as part of our clinical development program for Aficamten, we are now considering the best path forward for a trial in patients with non obstructive HCM and expect to clarify our approach later this year. And as we have previously stated, in addition to exploring the opportunity to address hyper contractility, in obstructive and non obstructive HCM, we believe there is also a subset of heart failure patients with preserved ejection fraction whose underlying cause of their disease is driven by left ventricular hyper contractility and hypertrophy. These patients may also benefit from treatment with an optimized next class cardiac myosin inhibitor. And we remain interested in pursuing this population as the development program matures. And with that, I'll turn it over to Robert Wong, who will provide an update on our financials.
