Thanks, John. Our portfolio of partnerships continues to expand the number and to increase in diversity. We have some important updates today and we’ve noted a few new regulatory approvals recently. In March, we saw the FDA approval of Sage Therapeutics’ ZULRESSO, also known as brexanolone injection that uses our Captisol technology in its formulation. ZULRESSO is the first and only treatment specifically indicated for postpartum depression or PPD and its approval was based on results from three pivotal clinical trials, showing that treatment provided significant and rapid reduction of depressive symptoms within days. Postpartum depression is the most common medical complication of childbirth and is estimated to affect approximately 400,000 women annually in the U.S. This is a license that dates back to 2011, which we struck shortly after our acquisition of the Captisol technology. Our partners at Sage expect to launch ZULRESSO late this month, early next month, excuse me. And we look forward to seeing it on the market. CASI Pharmaceuticals announced it received approval to market Captisol-enabled EVOMELA in China. Because of Ligand’s investment in clinical stage R&D for the program years back, we earn a 20% royalty on global sales for EVOMELA. We’re impressed with the management team at CASI, and their focus on the asset. CASI has stated publicly that they see revenue potential for EVOMELA in China of more than $35 million annually. Daiichi Sankyo received approval in Japan for esaxerenone now referred to by the trade name MINNEBRO for hypertension, and announced last week that they launched the product this month. In addition to the hypertension indication, we note that they’re now running a pivotal Phase 3 study of MINNEBRO in patients with diabetic nephropathy, also known as diabetic kidney disease. Many of our other partners are also progressing towards data readouts or have recently announced or plan to announce clinical data at major medical meetings. A few weeks back our partners at Viking Therapeutics presented new data from their Phase 2 study of VK2809 in patients with non-alcoholic fatty liver disease and elevated LDL cholesterol at the late-breaker session at the International Liver Congress or EASL meeting. Patients receiving five milligram daily doses of VK2809 demonstrated statistically significant median relative reduction in liver fat content of more than 53%. Importantly, 88% of patients receiving VK2809 experienced a greater than 30% reduction in liver fat content at 12 weeks, including all patients receiving five milligram daily doses. And VK2809 was safe and well tolerated at all doses studied with no FAEs reported in any cohort. The results reported at five milligram are similar to those obtained at higher doses and support our general enthusiasm for VK2809’s promise, and as a potential therapy for patients with NASH. Viking has stated that the totality of the data suggests a differentiated therapeutic profile with the potential to improve liver health and provide global benefits on systemic lipids, such as LDL-C and arthrogenic proteins. We’re encouraged by VK2809’s safety and tolerability profile, and in particular, that no FAEs have been observed in any of Viking studies. Experts seeing the data at EASL have commented that the clinical research suggest that reducing liver fat by 30% or more increases the likelihood of a potential histological response in NASH patients. Since more than two thirds of patients receiving VK2809, demonstrated at least a 50% reduction in liver fat, there is an expectation for a higher likelihood of improved liver histology, and that the robust improvements in liver fat content combined with the reduction in plasma lipids, such as LDL-C suggest a potential for cardio protective benefit of VK2809 in these patients, which would represent a promising and novel profile. Viking plans to initiate a Phase 2b trial in patients with biopsy confirmed NASH later this year. Our partner Palvella’s work on the [indiscernible] Phase 2/3 study of PTX-022 remain on track with significant clinical operations resources dedicated to patient enrollment and successful study execution. And patient recruitment is now underway at multiple academic and commercial sites. PTX-022 is addressing an orphan disease called pachyonychia congenita or PC. PC is a rare chronically debilitating and lifelong myogenic disease in which mutations of genes responsible for keratin production lead to disregulated keratinocyte proliferation, increasing skin fragility and impaired skin barrier function on the bottoms of the feet. As a result, affected individuals experience difficulty with walking, which frequently necessitates use of either ambulatory aids or alternative forms of mobility such as crawling. We’re pleased to see Palvella’s focus and progress on the trial. I’ll also update on the status of RVT-1502, the glucagon receptor antagonist, that’s partnered with Metavant. I’d mentioned on our last call that we expect the start of a clinical proof-of-concept trial this year for RVT-1502 in Type 1 diabetes. Given a very recent update from our partners at Metavant, we no longer expect to see that clinical trial start this year. Metavant has had discussions with the FDA, who have requested additional non-clinical studies specifically for chronic use settings. Metavant is evaluating its plans for the program, and we expect them to provide a program update. They have an expert project team working on this and we continue to be impressed with the overall scope and the experience base of the team at Metavant and we look forward to their update. The ASCO 2019 Annual Meeting in Chicago will start at the very end of this month and we’ve noted a number of presentations from our partners. We view the presentations as a representation of the diversity of our partner base, the drug targets they’re pursuing and the underlying technologies from Ligand’s portfolio. These include an oral presentation of Cantex Pharmaceuticals CX-01 Phase 2b data in AML. CX-01 is a polysaccharide derived from the class of compounds known as heparinoids, which have long been known to possess biologic and potential therapeutic properties separate from their well known use as anticoagulant. In addition to the results of the Phase 2b AML trial, encouraging top-line results from a Phase 2 in refractory MDL – MDS were reported at ASCO last year. Cantex has indicated publicly that it plans to advance development of CX-01, and start a Phase 3 trial in AML. And CX-01 has received orphan drug and fast-track designations from the FDA for AML. The license associated with this program dates back to 2009 when Ligand licensed patent for desulfonated heparin technology to ParinGenix, which is now known as Cantex. Also at ASCO, there are multiple presentations for Kyprolis, in newly diagnosed and relapsed-refractory multiple myeloma, as well as one in small cell lung cancer. Additionally, we note Merck KGaA’s presentation of Captisol-enabled M6620 in combination with the PARP inhibitor, thaliperib in solid tumors. And MEI Pharma is presenting new data related to Captisol-enabled ME-344 in breast cancer and Sermonix will also present data related to Lasofoxifene use as a treatment for ER-positive metastatic breast cancer. Lilly will also be presenting new clinical data on Captisol-enabled prexasertib, which we note they disclosed – they have removed from development in their earnings call earlier this week. For the first time at ASCO, we also note two presentations from OmniAb partners, one from Arcus Biosciences on their Phase 1 study with their OmniAb-derived anti-PD-1 monoclonal antibody AB122 and another from CStone from a recently completed Phase 1 study in advanced solid tumors with their anti-PDL1, CS1001, which is their lead compound that is now in Phase 3. Switching now to our technology platforms and starting with OmniAb. Our OmniAb antibody discovery platform has continued to grow, and rapidly drive the expansion of our portfolio of partnerships. We see OmniAb as our most valuable technology platform. We track the progress of our partners in a variety of ways, including tracking patent filings, clinical trial starts, and data events like the ones I just highlighted. We now see 24 published patent applications filed by our partners that claim an OmniAb-derived antibody, and see nine Phase 1 trials in progress, five Phase 2 trials and now for the first time a Phase 3 trial, which is CStone’s CS1001. The Phase 3 is known as the GEMSTONE-303 trial and it’s assessing CS1001 in combination with chemotherapy for the treatment of gastric adenocarcinoma, or gastroesophageal junction adenocarcinoma. We continue to add new partners, and many of our partners are expanding species use and adding programs that leverage our OmniChicken technology. We continue to innovate and maintain OmniAb’s place as a best-in-class technology. At the PEGS meeting in Boston, in April, our scientists presented data on and officially launched our newest transgenic chicken platform known as OmniClic, which is designed to generate antibodies with what’s described as a common light chain to facilitate the development of bispecific antibodies. The data presented at PEGS showed that OmniClic antibodies were highly diversified in their heavy chains, resulted in high affinity and high specificity antibodies despite there being little to no variation in their light change. A subtle change in the transgene design enabled this dramatic shift relative to the standard OmniChicken, where light chains are highly diversified and further demonstrates our teams’ world-leading technical command over genetic engineering. OmniClic received substantial attention at PEGS, and is already being utilized in partner programs. Turning now to the Vernalis Design Platform or VDP. This platform’s strengths are related to fragment and structure-based drug discovery, where protein structure determination, fragment screening and molecular modeling are closely integrated with medicinal chemistry to enable rapid and efficient discovery of novel drugs. Our VDP partnerships continue to progress very well, as we collaborate on a variety of novel targets. Data from our partnership with Servier was presented at the recent AACR meeting related to the Phase 1 stage MCL1 inhibitor for cancer that Servier has now partnered with Novartis. The molecule was previously known as S-64315 at Vernalis and Servier, and now at Novartis is known as MIK665. And now, very briefly on Captisol. Captisol continues to provide value to our partners, as we expand our active Captisol Drug Master Files in the U.S., Canada, Japan and China. In addition to our DMS, the global footprint and the established quality profile are also significant value drivers for our partners. I note that we entered into new Captisol clinical use or commercial license and supply agreements recently with Merck KGaA, reVision Therapeutics, Takeda, Bexson Biomedical and a startup named SQ Innovation. And I’ll wrap up with some brief updates on activities with our internal R&D pipeline, starting with Captisol-enabled iohexol. As we announced this morning, we’ve now completed enrollment of 24 healthy volunteers in a single-center, randomized, double-blind two-period crossover study to determine the relative bioavailability of CE iohexol and a reference product, which is GE Healthcare’s OMNIPAQUE. The trial enrolled faster than we expected. This first trial is also assessing safety and tolerability and we now expect to have unblinded top-line data in Q3. We plan to present the clinical data and some new preclinical data at relevant medical and scientific meetings in the second half of this year and to assess partnering opportunities as well as targeted investments in the program that will drive partnering. We also now have five new internal antibody related programs that leverage the capability of our deeply experienced OmniAb team. We initiated the programs in mid-2018 and rolled them out at our Analyst Day in mid-March. We selected five immuno-oncology targets based on leveraging known biology with broad clinical and partner interest and where we could also leverage the benefits of OmniChicken in antibody discovery. The five programs are B7-H3, CD38, ICOS, TIGIT and TIM-3. Our team is generating partnering packages to include sets of novel, fully human antibodies, and we now have unique monoclonal antibodies for each target that our team is characterizing. We plan to initiate partnering dialog for the programs in the second half of this year. And I note that we’ve already received inbound interest in the programs very shortly after we unveiled them. And I’ll now turn the call over to Matt Korenberg to discuss the financials.
