Thank you, Phil. As Phil indicated, the approval of APHEXDA for stem cell mobilization in multiple myeloma patients represents the first true advancement in stems mobilization in over a decade. Our decision to commercialize effects to independently in the U.S. is key to our efforts to make this new mobilization agent available to transplant centers and patients as quickly as possible. I would now like to provide a brief update on our recent and ongoing activity supporting the commercial launch, which we initiated immediately after APHEXDA approval. First, it may be helpful to provide some statistics that support the significant opportunity that is in front of us, not just in terms of potential sales, but also an ability to help thousands of patients who today are having great difficulty mobilizing enough stem cells for transplantation. As a reminder, there are approximately 35,000 patients diagnosed with multiple myeloma each year in the U.S. And of those, we estimate that about 18,000 are eligible for autologous stem cell transportation. On these eligible patients, approximately 8,000 procedures per annually, a figure that has nearly doubled since 2010. Autologous stem cell transportation remains the preferred first-line treatment for patients with multiple myeloma. However, due to a number of factors, including an aging patient population and the increased use of three and four drug induction therapies, as Phil indicated, up to 47% of patients have had challenges collecting the target number of stem cells in one apheresis session. As we will cover in more detail shortly, the requirements for multiple apheresis session leads to potentially more adverse events, higher costs and tremendous inconvenience and mental hardship for patients. With the efficacy demonstrated in Phase 3 GENESIS trial, which supported the approval of effects to indecent indication, we believe we can overcome these challenges. We believe we are highly differentiated as a novel second-generation mobilization agent and that we have a significant value proposition for all stakeholders, that includes centers, patients and payers. Staying on the topic of differentiation for a moment, we have done extensive research on the market and have deep appreciation of the evolving landscape. Since our last earnings call and as expected, multiple abbreviated new drug applications or ANDA have been approved for generic [indiscernible] leading to rapid and significant price erosion for the first-generation mobilization agent. This is something that we anticipated and what we have incorporated into our model. And why we consider, plerixafor to be in the same overall market basket at APHEXDA, it is not the same as APHEXDA. We have a highly differentiated product profile based on our stronger and more consistent mobilization outcomes. And our early discussions with customers support that the centers appreciate the innovation as we look to address their need for a better mobilizer. As such, we have indicated previously that we have price effects at [indiscernible] per vial. We believe this price adequately reflects the value that APHEXDA adds to the autologous stem cell transplant treatment landscape. Further, notwithstanding the existence of lower-priced generic plerixafor. We believe the differentiated clinical attributes APHEXDA will drive long-term adoption and allow it to evolve into the new standard of care for mobilization. Over time, we strongly believe that differentiation will outweigh drug price as centers adopt the best treatment paradigm for their patients. As we indicated previously, our first priority has been to educate transplant centers on the unmet need of roughly 8,000 patients who progress to autologous stem cell transplant each year. We estimate the top 80 centers out of the band 212 nationally perform approximately 85% of all stem cell transplant procedures. Since approval, we have established initial contact with all of our top-tier centers and root activity has been extremely high. Increases shares can be in short supply at many transplant center and the potential for APHEXDA to allow for the collection of the targeted number of stem cells quite often in a single apheresis session should allow for the more efficient scheduling and utilization of those tiers. This is of significant value to transplant centers, particularly those that perform a high number of procedures. We are in ongoing discussions with pharmacy and therapeutics committees at those centers that require positive PMP formulary decision prior to trialing the product and including APHEXDA in their protocols. We are making consistent and steady progress. We believe an important factor driving the future success of APHEXDA is inclusion in clinical treatment guidelines. Shortly after approval, APHEXDA was included in the national clinical practice guidelines in oncology otherwise known as NCCN, for stem cell mobilization broadly, including multiple myeloma. The American Society for transplantation in cellular therapy or ASTCT is also working on updated guidelines, which we anticipate next year. Currently, ASTCT to [indiscernible] recommendations call for a recommended collection target of 3 million to 5 million cells per program and double that target with multiple transplants are planned. Recall that in the GENESIS trial, the median number of CD34 stem cells collected on the first day of apheresis was $8.5 million in the treatment arm versus $1.5 million in the control arm. As Phil indicated earlier, the addition of Motixafortide to G-CSF also allowed 88.3% of patients to undergo transplantation after only one apheresis session compared to 10.8% in the G-CSF, given the demonstrated performance of APHEXDA relative to the current treatment guidelines, we are confident that we will ultimately gain inclusion. Turning now to payers. The success of any new therapeutic launch is contingent upon establishing broad, affordable access from a coverage and reimbursement perspective. This includes not only national and regional commercial health plans, but also the centers for Medicare and Medicaid services since a significant number of multiple myeloma patients are older and therefore, receive their health care through Medicare. The immediate upfront cost of stem cell collection independent of drug costs is 13,850 per patient and can range from 6,300 (ph) to $48,500 and the cost of one apheresis session is 6,200 to 6,600 again independent of drug costs. For the ability to more predictably and reliably achieve the target number of stem cells required for transplantation and fewer apheresis sessions can result in significant savings to payers over time. Payers view the effects of clinical data very favorably. And as a result, we have already established unrestricted access to over 90% of covered lives. This represents a mix of both commercial and government payers, and we continue to work to increase this number so that APHEXDA is as broadly accessible to patients as possible. In summary, I am very pleased with our launch progress to date. Both our commercial and medical affairs teams, which include many individuals with decades of experience in both stem cell mobilization and multiple myeloma are generating results in the early stages of this launch as we continue to engage with top transplant centers, physician leaders and payers on this exciting new treatment option. At this point, I'll turn the call back to Phil to provide an update on our other programs.
