Thanks, Kurt. I want to provide everybody with a detailed overview of our two late stage assets, but equally as important, I want to capture the energy and enthusiasm of our teams working on these assets. Let me start with poziotinib. There was a recent publication in Nature Medicine, the Nature Family of Journals is synonymous with major medical breakthroughs and we couldn't be prouder to see our poziotinib featured in the April 2018 edition. While the key takeaways of that article was that in the first 11 patients, the confirmed objective response rate was 64% and the median PFS had not been reached after a median follow up of 6.6 months. And this compares to less than 2 months of PFS on currently available treatments. In addition, the adverse event profile was consistent with drugs in the class. But what really has thought leaders excited about that paper, if you go back and read it is it clearly articulates the story of translational medicine. Seeing the preclinical modeling, transfer to early clinical results has the KOL community wildly excited about what is the potential for poziotinib to treat these patients. In addition, we then went to AACR in Chicago, having a chance to have interacted with a lot of the traffic on our poster as well as KOLs, there were three main takeaways as I took -- from that poster. First, this was the first time that we had a poster specifically designated to the HER2 exon 20 insertion mutations. The preclinical modeling of the HER2 exon 20 insertion mutations was presented and is expected to be predictive for the effectiveness of poziotinib in this patient population. Second, the original compassionate use patient was presented. This patient experienced significant clinical and radiographic response after four weeks of treatment. In addition, KOLs were thrilled to see that circulating DNA in that particular patient with below detectable limits, furthering their confidence that the preclinical modeling has the potential to translate into the clinic. Finally, the initial HER2 exon 20 insertion mutation prevalence data across many solid tumors was presented. While this is the first cut, it fueled our enthusiasm to explore poziotinib in solid tumors beyond lung cancer where these mutations are present. If I step off the page, in all of my travels with KOLs, this data could impact a larger number of patients beyond lung cancer and we are wildly excited to further this development. We're currently working to design a basket study with MD Anderson, KOLs from around the world and leading statisticians to quickly assess the opportunity. We expect to have further updates on our progress later this year. Let me update on the two ongoing lung cancer studies, the MD Anderson sponsored study and the Spectrum multi-center study. First, on the MD Anderson study. To see that the 50-patient cohort in the EGFR exon 20 insertion mutation population is fully enrolled, is an excellent result. If we think back just a year ago, this cohort began as a 30-patient cohort and due to the demand in the unmet medical need, we quickly increased this cohort to 50 patients and it's now fully enrolled. The HER2 cohort is also approaching 50% enrolment. The focus of the study is not just in the United States as the MD Anderson study has enrolled patients from around the globe and we are now ramping up for our trial in Europe. The Spectrum sponsored study is off to an excellent start. We just had an energized meeting in Washington DC and the enthusiasm from the investigators was contagious. We currently have 20 sites up and running, many more on the startup process and we’re currently opening sites in Europe that will improve logistics for patients around the world and will position us well for our filings outside the United States. Consistent with the MD Anderson experience, our enrolment is exceeding our expectations. This speaks both to the enthusiasm of our assets as well as the clear unmet need for patients. MD Anderson is planning to submit additional data from their study for presentation at the World Lung conference in Toronto in September. Let me stay on poziotinib and focus on some fundamentals, both IP and regulatory strategy. As it relates to the intellectual property of poziotinib, Spectrum has a strong portfolio of issued patents that cover composition of matter, methods of manufacturing in formulation. In addition, as you may have seen this morning, we have entered into an exclusive licensing agreement with MD Andersen that includes the rights to file patents related to methods of use to treating cancer patients with EGFR and HER2 exon 20 mutations as well as any unidentified discoveries related to poziotinib that may come from Dr. John Heymach’s lab and MD Anderson in the future. If granted, these patents would effectively extend pozi’s IP to 2037. While the specific financial terms have not been disclosed due to confidentiality agreements of multiple parties involved, what I can say is that Spectrum's royalty obligation remains consistent with what has been publicly disclosed with royalties between the low and mid-teens. If I look at the main point here, to have an IP extension to 2037 in the mutated cancer space if patents granted solidifies our partnership with a leading academic institution of MD Anderson has us thrilled with this agreement. On the regulatory side, we are in regular discussions with the FDA to expedite the regulatory approval for poziotinib. We’ve conducted a pre-submission meeting with the agency along with Dr. Heymach from MD Anderson. The tone of the meeting was very encouraging and the understanding around the unmet medical need for patients with exon 20 insertion mutations was very clear. As we evaluate the criteria for breakthrough therapy designation, we believe that pozi meets the criteria if the early data continues. When we look at those criteria, there are two. First, there needs to be a clear unmet medical need and second, the potential for substantial improvement over existing therapies needs to be there. We think pozi qualifies for both. Based on our discussions, we should know if poziotinib qualifies for breakthrough therapy designation by the end of the year and the MD Anderson data will be the backbone of that decision. We couldn't be more excited about our development program with poziotinib. You may have also seen this week a press release regarding Thermo Fisher, which ultimately is important for both regulatory submission as a companion diagnostic and our commercial strategy. Thermo Fisher pioneered next generation sequencing as lung cancer when their Oncomine RX target test, which was approved by the FDA in June of 2017. As promising clinical data continues to emerge with pozi for the treatment with patients with EGFR and HER2 exon 20 insertion mutations, the development of the Oncomine RX target test will aid in faster detection and treatment of patients who are not well served by currently available treatments. Let me transition to Rolontis. In the first quarter, we announced Rolontis met the primary efficacy endpoint of non-inferiority in duration of severe neutropenia between Rolantis and pegfilgrastim in the advanced stuff. This study also confirmed that the adverse event profile was similar between the two treatment arms. We also announced the full enrolment of our second Phase 3 study, the RECOVER study. The next two data milestones for Rolontis will be the Phase 3 data abstract released online by ASCO on May 16, followed by an oral presentation at MASCC Indiana between June 28 and 30. Our team is diligently working to prepare for our pre-BLA meeting with the FDA to make sure that everything is in line for preparation of our planned Q4 BLA submission. If approved, we will have the opportunity to compete in a multi-million dollar market with a novel asset. In closing, I hope you could see, we have a ton of positive things happening within our operations. The energy of the company is palpable and I couldn't be prouder of the team as they are executing with both precision and excellence. We look forward to providing you with additional updates as the year progresses. With that, I’ll turn it back to Joe.
