Thanks Michael. Good afternoon, everyone and thanks for being with us on the call. So we certainly made significant progress across all of our pain and pruritus development programs during the second quarter and we will summarize that progress and then talk about upcoming milestones on the call this afternoon. Starting with I.V. CR845 for acute post-operative pain, in June, an independent data monitoring committee completed a pre-specified interim conditional power analysis of our adaptive Phase 3 trial in patients with acute post-surgical pain. The committee revealed that both doses being evaluated in that trial were generally well-tolerated and based on their conditional power analysis, the trial continues to test both doses versus placebo in up to 450 patients. We anticipate completing enrolment later this year and enhancing top line data thereafter. Recently, we also had two significant events in our CKD pruritus program that underscore CR845’s potential in this indication and also laid the groundwork to expand this clinical application into a broader patient population. In June, I.V. CR845 received breakthrough therapy designation from the FDA for the treatment of moderate to severe CKD associated pruritus in patients undergoing haemodialysis. As a remainder, breakthrough designation is granted to companies to expedite the development and review process for new therapies addressing serious or life threatening conditions where preliminary clinical evidence indicates that the drug candidate may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints. Basically, this allows the FDA to potential expedite CR845 development process in these patients and we will be discussing the complete pivotal program in that context in our upcoming end of Phase 2 meeting with the agency planned for this quarter. There are currently non approved therapies in the U.S. for CDK associated pruritus and the FDA’s decision to grant breakthrough therapy designation is recognition of both the significant online medical need and the potential of I.V. CR845 to address that. Also recently, we announced summary data from a Phase 1 trial of oral CR845 in haemodialysis patients which identify tablet strength eliciting plasma levels that were comparable to or exceeded those observed with clinically efficacious I.V. doses in our completed Phase 2 trials with I.V. CR845. The potential to develop oral CR845 for chronic dosing provides the possibility to significantly expand the addressable patient population in CKD and also possible other pruritic indications that we’ll talk about. For the estimated 200,000 to 300,000 patients with CKD associated pruritus who are on hemodialysis, we believe that I.V. dosing after each dialysis session, that’s 3x a week maximizes convenience and patient compliance. For the estimated 4 million CKD associated pruritus patients, primarily stage 3 to 5, who are not on dialysis, oral CR845 should approved an appropriate means of drug administration. Additionally, we believe that by virtue of its combined anti-inflammatory and direct anti-pruritic mechanism of action as well as published clinical data from ex-U.S. studies with non-selective kappa agonist, we believe CR845 may have a treatment effect in other pruritic indications. To that end, we’re planning to submit an IND for Oral CR845 in treating chronic liver disease associated pruritus in the fourth quarter of this year and intend to begin a clinical program in CLD shortly thereafter. So this program will focus primarily on patients experiencing moderate to severe pruritus associated with hepatitis B and C infection, primary biliary cholangitis and general liver cirrhosis, a total of approximately 2.5 million patients in the U.S. Moving on to chronic pain, during the second quarter, we announced top line data from our Phase 2b trial of Oral CR845 in osteoarthritis patients, osteoarthritis of both the knee and the hip. While we were disappointed that the study did not meet the primary endpoint across the full patient population, we were encouraged by the activity at the highest 5 mg dose in hip osteoarthritis patients where we saw statistically significant result on the primary pain endpoint as well as on patient global impression of change and a convergence of other endpoints. So we continue to analyze this data set in consultation with our Pain KOLs and we plan to update you on our clinical plans for best indication next quarter and Joe Stauffer will add some more color to this shortly. Finally, very recently, we were pleased to announce this week that Dr. Mani Mohindru will join us later this month as our new Chief Financial Officer. Mani brings both financial and significant business strategy experience, which I believe will be an important resource as we grow Cara towards a commercial organization. I also want to finish by thanking Joe Schoell on his last earnings call today – with us today, for the many significant contributions, financial and otherwise, he has made to Cara since our days as a small privately backed biotech venture through IPO and 2 significant follow-on offerings and so we wish Joe the very best in his retirement. With that, I will turn the call over to Joe Stauffer, who will review our clinical trial programs and also the recently announced results in some greater detail. Joe?
