Thank you, Elias. Starting with our Pharmaceuticals segment, revenue increased to $57.7 million for the fourth quarter of 2023 from $46 million for the comparable period of 2022. Revenue from products, including our international pharmaceutical businesses and RAYALDEE, increased by $5.1 million, reflecting from improvements in the number of prescriptions and in overall net price. Further, revenue increased as a result of gross profit share payments from Pfizer due to the global launch of NGENLA, resulting in $12.2 million of revenue during the quarter. The fourth quarter revenue includes a catch-up payment for the U.S. market related to the third quarter of $3.1 million. As I mentioned last quarter, the U.S. launch occurred mid-August, and Pfizer was delayed in reporting our gross profit share amounts. And as a result, none were included in our third quarter results. Costs and expenses were $73.8 million for the fourth quarter of 2023 compared to $68 million for the 2022 period. Research and development expenses for the fourth quarter of '23 were $18.7 million compared to $16.6 million for the comparable period of 2022. This increase reflects activities for our ModeX development programs, partially by decreased spending on NGENLA as well as an R&D tax credit for our Irish activities. The resulting operating loss for the quarter ended December 31, 2023, was $16 million, a $6 million improvement from the operating loss of $22 million for the fourth quarter of 2022. Amortization expenses related to intangible assets were $16.4 million and $16.5 million for the 2023 and 2022 4th quarters, respectively. Moving to our Diagnostics segment. We reported revenue for Q4 2023 of $124.2 million compared with $139.4 million for the 2022 period. This decline primarily reflects lower COVID testing of $7.1 million as well as a change to our estimated collections of $8.1 million, partially offset by increased testing volumes. Costs and expenses increased to $166.4 million for the fourth quarter of 2023 from $162.5 million for the 2022 period. Operating loss for our Diagnostics segment included a change in estimated collections as well as approximately $4.7 million of nonrecurring costs related to employee severance and retention programs associated with our efforts to return to profitability. Depreciation and amortization expense were $8.1 million and $8.7 million for the 2023 and 2022 periods, respectively. Turning to our consolidated financial results. For the fourth quarter of 2023, we reported an operating loss of $69.1 million compared to an operating loss of $55.3 million for the 2022 quarter. Net loss for the fourth quarter of 2023 was $66.5 million or $0.09 per share, which compares with a net loss of $85.2 million or $0.11 per share for the 2022 quarter, reflecting lower noncash mark-to-market losses related to our investment in GeneDx. I'd like to briefly comment on our balance sheet and the recently completed refinancing of our convertible debt. On December 31, we had two convertible debt issuances that were set to mature in early 2025. Our 4.5% notes, which were held by a number of institutions, and our 5% notes, which were primarily held by Dr. Frost, Dr. Hsiao and a long-term investor of OPKO. In consultation with our advisors at JPMorgan, we chose to issue new five-year notes, reducing our coupon interest rate to 3.75% and took advantage of the strong demand from institutional investors to raise a total of $230 million. We used the proceeds to buy back the outstanding 4.5% notes and the 55 million shares of our common stock, and we added approximately $25 million in cash to our balance sheet. Our 5% note holders exchanged their principal and accrued interest of approximately $71.1 million into notes with identical financial terms as the 3.75% note holders. This refinancing strengthened our balance sheet, reduced the number of shares outstanding and provided the company with additional cash to fund our ongoing development activities. The offering was oversubscribed and brought in an impressive group of new prominent investors to OPKO. During 2024, we anticipate receipt of additional non-dilutive cash payments under our existing collaborations with Merck, BARDA and other potential transactions as the year progresses. As we look ahead, we're providing the following financial guidance with the following assumptions. For our Pharmaceuticals segment, there are a number of factors that impact our gross profit share payments from Pfizer, including revenue from product sales of GENOTROPIN and NGENLA. Global sales of GENOTROPIN for 2023 as reported by Pfizer were $539 million. Pfizer has not separately reported sales of NGENLA. However, we have observed consistent prescription growth globally for NGENLA as reported by IQVIA and Symphony. As such, for the full year, we estimate our gross profit share will be between $40 million and $50 million, although we anticipate that a number of scenarios may impact sales of GENOTROPIN and NGENLA globally. We assume a stable foreign exchange rate for our ex U.S. Pharmaceutical businesses, which will allow for continued and profitable growth. R&D expenses for the first quarter of 2024 will reflect higher activities related to our ModeX programs, including CMC and efforts related to the initiation of our first immuno-oncology clinical trial. Those increased activities will be partially funded through our BARDA agreement and partially offset by lower R&D costs related to the wind down of our clinical operations for the ongoing open-label pediatric extension study for NGENLA, which we expect to substantially complete by the end of the first quarter. For our Diagnostics segment, as Elias outlined, we are diligently working to align the business to achieve cash flow breakeven by the middle of 2024 and profitability by the end of the year. This work includes consolidating our geographic footprint and rationalizing our test offerings. As a result, we expect our client mix to improve and cost structure to appropriately support our go-forward strategy. During this transition phase, we expect consistent core testing volumes with a slight increase in the average per patient collection amount due to our revenue cycle management initiatives, partially offset by volume impact due to several weather events that occurred during the first quarter already. Before considering any nonrecurring cost that may result from our restructuring activities, we expect our cost and expenses to decline sequentially by $7 million to approximately $159 million. As a result, we expect the following for the first quarter of 2024: total revenues between $180 million and $185 million; revenue from services between $126 million and $130 million, revenue from product sales between $36 million and $40 million; and other revenue between $14 million and $18 million, inclusive of the estimated Pfizer gross profit share payments between $9 million and $11 million. We expect first quarter costs and expenses to be between $235 million and $245 million, including R&D expense between $20 million and $29 million, dependent on the timing for certain CMC activities for our ModeX programs and depreciation and amortization expense of $26 million. That concludes our prepared remarks. And thank you for your attention. Operator, let's open the call for questions.
