Good afternoon and thank you for joining us today. I'd like to begin the call with the key takeaways for the quarter. Firstly, we continue to execute well across our clinical development program for PEGPH20, highlights include continuing to initiate sites in countries around the globe and our phase 3 pancreatic cancer study HALO 301 progressing towards a dose expansion portion of our trial starting PEGPH20 with KEYTRUDA. And enhancing the selection of PEGPH20 for inclusion in the Pancreatic Cancer Action Network's groundbreaking Precision Promise Initiative. Secondly, the value of our currently marketed product on our ENHANZE platform continues to grow through increased conversion rate in launched countries and expansion into new geographies, indications and patient populations. We reported yet another quarter of record royalty revenues, as sales of Herceptin SC, MabThera SC and HyQvia drove an increase of 6% sequentially and 58% from the third quarter of 2015. We also announced last week that the FDA has accepted Genentech's biologics license application for subcutaneous formulation of rituximab using our ENHANZE technology in multiple blood cancer indications. This development represents a meaningful step towards bringing rituximab SC to patients in the United States. And thirdly, we continue to demonstrate our financial strength exiting the quarter with more than $200 million in cash and raising the lower end of our guidance ranges for both revenue and year-end cash. The ability to grow our topline as we invest for the future in oncology is a key differentiator in our business model and continues to distinguish the company in the third quarter. For additional details on our progress, I'll start with an overview of our strategy. As a diversified oncology biotech company, we operate our business and make investment decisions in two strategic pillars. The first pillar is our oncology pipeline with investigational drug PEGPH20 at the core. PEGPH20 temporarily degrades hyaluronan, a glycosaminoglycan or chain of natural sugars in that body that can accumulate around certain tumors and constrict the tumor vasculature. In animal models, we have demonstrated that degrading hyaluronan or HA reduces tumor pressure, increasing blood flow and thereby the access of cancer treatments into the tumor. To give a sense for the high HA incidence rate, looking at the US and EU5, we estimate that there are approximately 25,000 high HA pancreatic cancer patients and an additional 50,000 non-small cell lung cancer gastric cancer and breast cancer patients are projected to be high HA. Our work in oncology is funded in part by the second pillar of our strategy which is centered on our licensing agreements with the six marquee partners including Roche, Baxalta, Pfizer, Janssen, AbbVie and Eli Lilly. These partnerships deliver more than $100 million in annual revenues to the company and between our currently marketed products and products that are in development using our technology. Analyst project sales for these innovator products in excess of $25 billion in 2025. Clearly the resulting royalty stream to Halozyme will depend on the number of indications developed and the degree of market penetration. But this provides the sense of the caliber of the products we are being studied with and the potential for our ENHANZE platform. Now let me begin by providing some additional details on PEGPH20. We are furthest along in our study of PEGPH20 in pancreatic cancer and share data from stage one of the HALO 202 study during the American Society of Clinical Oncology Annual Conference in June. Stage two of HALO 202 study enrolled a total of 133 patients and we estimate 35% to 40% of those patients will be determined retrospectively to have high levels of HA. The key objective of stage two is to test the effectiveness of prophylactic enoxaparin to reduce thromboembolic events in the PEGPH20 treatment arm. It is also our plan to analyze efficacy in patients with high levels of HA based on the cutoff established with the Ventana companion diagnostic. Recall the company is blinded to the stage two efficacy data and we have a P&C or a Data Monitoring Committee in place who are advising us on both safety and when the efficacy data is mature for analysis. We were recently informed by the independent statistician for the Data Monitoring Committee that the stage two progression free survival data are not yet mature for analysis. As a result, we now expect the reporting of data may move to 2017 depending on when the data are mature. We forward to analyzing and hearing the topline results of this study once we receive confirmation from our DMC that the data is mature. Moving now slide 2 for an overview of our phase 3 study in pancreatic cancer in which the first patient was dosed in March of this year. HALO 301 is designed and powered to evaluate progression free survival and overall survival in HA-high patients. This study is a 420 patient global double-blind placebo controlled randomized trial of patients with stage four pancreatic ductal adenocarcinoma prospectively identified and included based on high levels of HA. We're proceeding in the study with two primary endpoints; progression free survival and overall survival. And plan to conduct an interim analysis from the target number of progression free survival events is reached. Based on interim analysis, the Data Monitoring Committee will have the option to recommend we stop the study based on efficacy, continue it to the target norm of 420 patients, increase enrollment to up to 570 patients for the final overall survival assessment or stop the study for futility. If the progression free survival data show the significant benefit in the PEGPH20 treatment arm and both the overall survival and overall risk benefit are supportive, these data may form the basis for marketing application in the US and a conditional marketing authorization in Europe. I'm pleased to say that we continue to see strong global interest in the study with approximately 200 sites in 20 countries participating. Multiple site initiations are taking place each week towards our goal of activating approximately 90% of our clinical sites by the end of this year. During this quarter, we also announced our participation in the Pancreatic Cancer Action Network’s Precision Promise Initiative. This clinical trial, the design of which is still being finalized would be the first of its kind seeking to offer treatment options to patients based on the molecular profile of the pancreatic tumors. Using the companion diagnostic assay developed with our partner Ventana, patients with high levels of HA may receive PEGPH20 as part of the regimen. This trial will bring together clinicians, researchers and drug developers with plans to begin enrolling patients at 12 initial US consortium site in the spring of next year. Turning to Slide 3, I’d like to provide an update on our clinical development progress to assess pan-tumor potential of PEGPH20. The PEGPH20 plus KEYTRUDA or pembrolizumab trial is enrolling relapsed refractory stage 3B and stage 4 non-small cell lung cancer patients who have been treated with at least one platinum-based regimen or recurrent locally advanced/metastatic gastric adenocarcinoma patients who failed at least one chemotherapy regimen. Our goal in the study is that value of PEGPH20’s potential to improve the efficacy of immunooncology therapies as has been demonstrated in preclinical models. We recently entered the last patient in the current dose cohort and if this patient completes the treatment period without a dose limiting toxicity, it is our plan to move into dose expansion at the 2.1 micrograms per kilogram dose with the goal of enrolling approximately 40 patients. In preparation for the dose expansion, we are initiating additional sites in the US towards our target of approximately 30 sites. Technical cut-offs are now in place for prospects of selection of non-small cell lung cancer and gastric cancer patients based on HA. And finally we have our phase 1b/2 clinical trial with our collaboration partner Eisai. As previously announced, the first metastatic breast cancer patient was dosed in June and this study is ongoing. I would like to move to the second pillar of our strategy, our ENHANZE platform where we license rUpH20 enzyme to leading companies. Let me begin with the most substantial recent development which is the FDA’s acceptance of Genentech's BLA for subcutaneous rituximab in multiple blood cancer indications. This co-formulation with the ENHANZE platform is approved and marketed under the MabThera SC brand in countries outside the United States. Including all approved indications, Roche reported total 2015 sales of rituximab in the United States of approximately $3.5 billion. It’s estimated that the majority of these sales are blood cancer related making this one of the biggest potential opportunities in ENHANZE franchise history. Moving to our Pfizer relationship, Pfizer announced last week the discontinuation of its bococizumab global clinical development program due to the totality of clinical information now available for bococizumab taken together with the evolving treatment and market landscape for lipid lowering agents. Development of a subcutaneous version with ENHANZE have also been discontinued. Pfizer separately made a portfolio decision to discontinue development of a subcutaneous version of rivipansel using ENHANZE after completing the in-life portion of a single and multiple those phase 1 assessment that successfully demonstrated feasibility of large volume subcutaneous administration. Well disappointed with this portfolio decision, we are pleased that Pfizer continues to develop an additional program with the ENHANZE platform for an undisclosed target. Sale of our partners marketed products on the ENHANZE platform continue to grow reflected by the increase in our sequential and year over year royalty revenue. In particular, Roche indicated during their most recent quarterly call, that Herceptin SC now accounts for approximately 50% of total Herceptin sales volume in launched countries. We remain pleased by the continued progress of both Herceptin SC and MabThera SC in countries outside the United States. Slide 4 provides an overview of our current ENHANZE portfolio and the potential future opportunity associated with the platform. The top of the pyramid shows the current marketed products that are projected by analysts to exceed $5 billion in annual total revenues across all of their indications in 2025. We’ll receive a mid-single digit royalty on net sales with our royalty potential being based on the number of approved indications and market penetration. Our partnered pipeline which is in the middle of the pyramid includes phase 1 trials for Janssen’s anti-CD38 daratumumab in multiple myeloma patients, AbbVie’s HUMIRA being tested to help reduce the number of induction injections at higher doses and Roche’s study of Perjeta in HER2-positive breast cancer patients. With analysts and other sources projecting future sales totaling greater than $20 billion, we're very excited to be working with these companies to evaluate the potential of our combined technologies and to develop additional product offerings for patients. Janssen and their development partner Genmab have indicated the daratumumab SC phase 1 trial is progressing well and they are targeting the initiation of a phase 3 trial in mid-2017. Janssen has recently informed us that they are very encouraged by the phase 1 data and the opportunity to solidify their competitive position through the co-formulation with the ENHANZE technology. To this end, they recently have taken steps to file for patent protection for the co-formulation. Finally, we have four other targets that have been selected but not disclosed by our partners and 23 additional targets that have been licensed. We also continue to assess new deals to expand the value of our ENHANZE platform and believe approximately 150 targets are still available that may benefit from ENHANZE. While it is always hard to predict if and when a new deal may come, I can say this is something our team continuously work towards and we continue in dialog with a number of companies. In closing, I’m pleased with the commercial progress and see clear opportunities for continued growth through new collaborations and as we support our current partners in advancing their programs. With that I’ll now turn the call over to Laurie to discuss our financial results for the third quarter in greater detail. Laurie?
