Now I'd like to turn the call over to Dr. Frost.
Good afternoon, thank you for joining us today. During the second quarter, we made meaningful progress in improving operating efficiency and profitability and in advancing our product pipeline. ModeX continues to move forward with its present portfolio of five clinical trial programs in oncology, immunology, and vaccines, each with the potential to deliver first and best-in-class medicines. We initiated a phase I-IIa clinical safety and efficacy study in the U.S. of our GLP-1 glucagon candidate, and we plan to enroll 44 healthy volunteers and presumed MASH patients to assess single-dose tolerability and pharmacokinetics. OPKO Biologics is making progress with its human growth hormone antagonist to treat acromegaly. Its GLP-2 program for patients with short bowel syndrome and its oral PTH to treat hypoparathyroidism. NGENLA, our growth hormone product, partnered with Pfizer, continues to increase market penetration as we advance label expansion clinical trials.
I'm pleased that we ended the second quarter with a strong cash position and a solid balance sheet that continues to fund our R&D portfolio at a meaningful level, while also returning capital to shareholders through our ongoing stock repurchase program. With that brief overview, I'll turn the call over to Elias. Elias? Sorry, I was on mute.
Thank you, everyone, for joining us today. Thank you, Phil. Let me take this opportunity to highlight continued advancements in our pipeline targeting important unmet clinical needs across large markets. First, in immuno-oncology and immunology, I'll start with ModeX, where we now have five assets in the clinic and expect a sixth program, our in vivo CAR T asset, to begin first in human clinical trials by the end of this year or in early 2027. Our collaboration with Merck for MDX-2201 focused on a vaccine against Epstein-Barr virus, commonly known as the cause of infectious mononucleosis, but is also associated with several cancers and immune-related conditions such as multiple sclerosis, continues to advance. The program, fully funded by Merck, is in the late stages of data analysis of its completed phase I trial.
We continue to expect Merck to have the data to inform the phase II design by the end of this year, with a potential progression to phase II clinical study next year. MDX2001, our lead immuno-oncology candidate for solid tumors, including head and neck, esophageal, pancreatic, lung, and prostate cancers, continues to advance in phase I and is expected to conclude dose escalation and regimen optimization by Q3 or early Q4 2026. We expect early data to be presented at a medical conference in late 2026 or early 2027, and we're underway with initiatives to enable subcutaneous formulations. A differentiated tetraspecific design, MDX2001 combines dual tumor antigen targeting, Trop-2 and c-Met, with dual T cell activation, CD3/CD28, to enhance immune engagement and potentially deliver deeper, more durable responses than conventional T cell engagers.
MDX2003, our next generation tetraspecific, directed to CD19/CD20 on tumor cells and CD3/CD28 on T cell, is an engager expander designed to harness and amplify the body's immune system by precisely connecting T cells to B cell cancers, driving enhanced T cell activation and expansion to enable sustained antitumor responses. MDX2003 has entered its phase I clinical trial, is enrolling patients. In parallel, we are also evaluating the optimal path to explore autoimmune indications for MDX2003. MDX2004, our first-in-class trispecific, which is a CD3, CD28, and 4-1BB ligand immune modulator antibody fusion molecule engineered to rejuvenate exhausted T cells and other immune cells, primarily in heavily pretreated cancer patients, is enrolling patients in phase I. We expect to announce preliminary data in 2027.
Finally, MDX-2301, our fifth ModeX program in the clinic, fully funded by BARDA, is a multi-specific COVID-19 antibody that has been shown to be active against all prior and current circulating variants of the virus, aimed at the prevention of COVID-19, primarily in high-risk immunocompromised patients. We're completing enrollment of its phase I clinical trials in this third quarter of this year, with early results to be presented at medical meetings later this year or early 2027, which will inform next development stages. In addition to COVID multi-specific antibodies, BARDA is also supporting our multi-specific influenza program, which targets conserved regions of hemagglutinin to enable broad coverage across influenza A and B strains. We're currently conducting pre-IND work for this program. We're also excited by our continuing progress toward advancing our sixth ModeX asset, MDX-3001, into clinical trials following the successful completion of all preclinical studies.
Unlike traditional CAR-T therapy, we believe our in vivo CAR-T program is highly differentiated as it leverages our multi-specific antibody expertise and platform with targeted lipid nanoparticles, seeking to generate engineered T cells directly inside the patient body by delivering the CAR payload to the right immune cells in the body, which we can select due to our multi-specific technology. We are now in IND-enabling studies and expect to begin clinical studies by the end of 2026 or early 2027, potentially in cancer and autoimmunity indications. In May, MDX-3001 data was presented at the American Society of Gene & Cell Therapy, demonstrating in vivo CAR-T cell generation with B-cell depletion in blood lymphoid tissues, including spleen, bone marrow, and lymph nodes. Activity was confirmed in both humanized mouse and non-human primate models. Turning to research conducted with our partners.
We're pleased to note continued progress with our collaboration with Regeneron, which combines their extensive library of clinically validated monoclonal antibody binders with our modular multi-specific architecture across immunology, oncology, and metabolic diseases. We remain focused on advancing four initial discovery programs with Regeneron using the ModeX platforms to rapidly generate and optimize multi-specific antibody candidates with the potential to expand into additional targets over time. Regeneron is responsible for funding preclinical, clinical, and commercial development of selected assets, while OPKO is eligible for research, development, regulatory, and commercial milestones that could exceed $1 billion, as well as tiered royalties on global sales up to the low double digits. We have also advanced the development of the once-weekly dual GLP-1 glucagon agonist, OPKO-88006. The phase I/IIa randomized, double-blind, placebo-controlled clinical trial is open to enrolling participants in the U.S.
The first part of the trial is to evaluate the pharmacokinetic and tolerability of OPKO-88006 at 3 levels of ascending doses in healthy volunteers. The phase IIa portion of the trial will evaluate the safety and effectiveness of OPKO-88006 administered once weekly for 16 weeks in participants with presumed MASH or metabolic dysfunction-associated steatohepatitis. We're also steadily advancing programs in OPKO Biologics. Our parathyroid hormone program, in collaboration with Entera Bio, as a first-in-class oral long-acting PTH tablet for hypoparathyroidism, which is structured under a 50/50 economic arrangement, reported excellent preclinical results at the recent Endocrine Society or ENDO conference. The data showed that the tablet was well-tolerated, no safety concern identified, and calcemic effects were consistent with those reported for clinically validated injectable PTH replacement therapies for hypoparathyroidism. Ongoing studies are advancing this program towards first-in-human clinical evaluation with an intention to file an IND later this year.
Our long-acting human growth hormone antagonist program, or known as OPKO-8801001, which is designed to treat patients with acromegaly, is expected to advance to clinical trials at the end of 2026, based on the results presented at ENDO last month. With OPKO-8801001, we envision a once-weekly injection that could significantly improve upon the current standard of care, which requires daily injections. NGENLA, our long-acting human growth hormone commercialized by our partner, Pfizer, continues to progress commercially according to plan. In addition, clinical label expansion through ongoing studies are underway, building on pediatric growth hormone deficiency label to further expand both market access and geographic reach. Currently approved and commercialized in over 50 markets, the NGENLA long-acting pediatric growth hormone deficiency product is contributing meaningfully to recurrent cash flow.
Turning to our international pharmaceutical businesses, our Iberoamerica business continues to grow with sustainable profitability as we focus on accelerating top-line growth and driving further operating efficiencies. Further, RAYALDEE, our innovative vitamin D commercialized product, continues to perform to plan and is contributing nicely to our operating cash flows. For the quarter, global pharmaceutical product sales grew about 7% year to date as of June 30th of this year, due to favorable demand trends and as well as foreign currency tailwinds. I'd like to turn finally to our clinical diagnostics business. As previously announced, following the sale of select oncology and oncology-related clinical testing assets to Labcorp in 2025, we received $192.5 million payment at closing, along with an additional $18.4 million earn-out payment received in the second quarter of 2026.
We continue to strengthen BioReference's core diagnostics platform by leveraging our regional clinical lab operations and national specialty testing franchise with a proprietary 4Kscore Test, serving as a key driver of growth. We continue to see 4Kscore Test as a unique, high-value asset with a potential to deliver significant revenue and profitability as we broaden payer coverage and continue educating urologists and primary care physicians about its clinical utility. Therefore, as we operate with a more efficient footprint and an expanding menu of higher-margin services, we're progressing towards achieving breakeven and positioning the business for sustainable profitability. In summary, we're encouraged by steady advancements in our ModeX portfolio, which is fully engaged in clinical development, in our biologics portfolio and partner programs, while generating non-dilutive revenue and more profitable growth and cash flow from our global pharmaceutical business and BioReference Health.
With that, I'll turn the call over to Adam to review our financial results and outlook. Adam? Thank you, Elias. We ended the quarter with a strong cash position with over $300 million in cash equivalents, and restricted cash, which is more than sufficient to fund our ongoing operations and development plans while continuing to return capital to our shareholders through our share buyback program.
During the quarter, we repurchased 9.7 million shares for approximately $13 million. We have approximately $94 million authorized to repurchase additional shares of our common stock. Let's move to the financial performance of our diagnostics business. Revenue for Q2 2026 was $74.5 million, including $6.2 million from our 4Kscore Test. Revenue in Q2 2025 was $101.1 million, with the year-over-year decline expected due to the sale of our oncology customer accounts, Labcorp.
In the transaction that closed in September 2025, revenue from our retained business declined approximately $1.7 million versus the prior year, principally due to test mix changes as we continue to see the impact of shifting certain unprofitable but higher-priced esoteric testing to our strategic partners. Total costs and expenses were $69.8 million, down from $119.3 million last year, reflecting the September 2025 Labcorp transaction, as well as an $18.1 million gain from the receipt of the final earn-out payment from the transaction, which offset operating expenses, as well as the continued efforts to rationalize our cost structure to align with our more focused geographic footprint and test offerings. Our diagnostic operating income was $4.8 million, compared to an operating loss of $18.2 million in Q2 2025. Depreciation and amortization came in at $3.9 million for the second quarter of 2026, down from $4.9 million in 2025.
As Elias mentioned, we remain focused on achieving breakeven and operating profitability for this business. During the second quarter, the team executed on its overall plan, but had several operational headwinds, resulting in slightly higher costs and expenses. Principally in employee benefit costs and professional fees. With continued execution, we anticipate achieving these profitability objectives in 2026. Turning to our pharmaceutical business, revenue was $89 million in Q2 compared to $55.7 million in the prior year, with improvements across all revenue sources. Revenue from product sales increased to $42.9 million, up from $40.7 million, reflecting higher sales volumes in our international operations and foreign exchange tailwinds during the 2026 quarter, along with improved RAYALDEE gross to net benefits, which were partially offset by the timing of delivery of certain products within our CDMO business.
As we continue to focus on the profitability of RAYALDEE, the gross to net improvements we began to realize last year have resulted in meaningful cash flow from operations in 2026 while maintaining overall revenue levels. RAYALDEE contributed $8.1 million of revenue during Q2 2026 compared to $7.2 million last year. Our Pfizer gross profit share was $6.4 million for the quarter, an increase to 2025's $6.1 million. Pfizer's progress in the global commercialization of NGENLA continues to show consistent growth while the market transitions away from daily growth hormone products. BARDA funding was $5 million for the second quarter of 2026 compared to $6.5 million a year ago, reflecting the start of our clinical trial program under this collaboration. While the 2025 period included higher levels of CMC activities in our infectious disease antibody programs.
Finally, the overall increase was driven by $29.4 million in revenue recognized from Series A2 preferred shares that we received in connection with our partnership with Nicoya for the commercialization of RAYALDEE in the Greater China market. As a result, IP and transfer of other revenue was $46.1 million in Q2 2026 compared to 2025's $15 million. Costs and expenses for our pharmaceutical business were $88.2 million, increasing from 2025's $84.4 million, reflecting meaningful investments in our R&D programs. For R&D for Q2 2026, spending totaled $32.7 million, up from $29.8 million in the 2025 quarter, which reflects the increased levels of activities related to our early-stage clinical trials. Our pharmaceutical operating income was $8.8 million in Q2 2026 compared to last year's operating loss of $28.7 million. Depreciation and amortization expense was $18.5 million, which is slightly higher than 2025's $18.1 million.
For our consolidated financial results, total revenues for Q2 2026 were $163.6 million, compared to $156.8 million in the second quarter of 2025. Consolidated operating loss for Q2 2026 was $7 million, which improved from 2025's $60 million operating loss. Our net loss for Q2 2026 was $8.4 million, or $0.01 per share, which improved from 2025's net loss of $148.4 million, or $0.19 per share. The 2025 period included a $91.7 million of expense related to the exchange of our convertible notes. Looking forward to our outlook for the third quarter of 2026, we expect revenue to be $131 million-$142 million, with revenue from services of $75 million-$78 million, which reflects several assumptions around testing volumes and reimbursement pricing mix.
We expect pharmaceutical product revenue of $40 million-$44 million, we expect IP and other revenue to be between $16 million and $20 million, including Pfizer profit share of $8 million-$10 million. Total costs and expenses for Q3 are expected to come in between $180 million and $190 million, with our expanding investments in R&D to come in between $34 million and $38 million, which is partially offset by $5 million-$7 million in BARDA and other collaboration funding. Depreciation and amortization expense of approximately $22 million. Moving to our outlook for the full year 2026, we're adjusting our full year guidance to reflect several of the first-hand transactions and trends.
For the year, we now expect an increase to our previously issued guidance, with total revenue now expected to be between $560 million and $585 million, with revenue from services contributing $296 million-$306 million, and pharmaceutical product revenue of $164 million-$174 million. While other revenue from our partner collaboration agreements is expected to be between $100 million and $105 million, including profit share from Pfizer of $34 million-$37 million. We've reduced our total cost and expenses to now be in the range of $710 million-$740 million, which excludes any future one-time items. Our full year investment in R&D is continued to expect to be between $125 million and $135 million, offset by funding from BARDA of $18 million-$22 million, as well as reimbursement from Regeneron under our collaboration agreement. Depreciation and amortization expense is expected to be approximately $95 million.
This concludes our prepared remarks. Operator, let's open the call for questions.
Thank you. We will now begin the question and answer session. To ask a question, you may press star then one on your touch tone phone. If you are using a speakerphone, please pick up your handset before pressing the keys. If at any time your question has been addressed and you would like to withdraw your question, please press star then two. Our first question for today will come from Brian Chang with J.P. Morgan. Please go ahead. Thanks for taking our question.
This is Sarah on for Brian. Just two questions from us. The first question being, how do you think about target and indication selection for your first in vivo CAR-T program in the clinic? What type of collaboration with pharma will you be looking for? The second question is for the 88006 molecule. What do you need to see to justify moving into larger MASH study, weight loss, liver biomarkers, tolerability, dose frequency, anything like that? Thank you. Let me take the second one, Gary Nabel can handle the first one about 2001, about the MDX 2001.
Well, what we're doing really is showing that this molecule has a competitive profile to any other competitors, there are a couple of competitors out there. That's what we want to demonstrate in phase I and phase II-A, both in normal volunteers at the dose tolerance of 3 dose levels, in the subsequent phase, really study patients with MASH. Now, when we study those patients, we're not going to have biopsies to start with.
We're going to have a combination of factors that are known to correlate with the presence and degree of MASH, including fatty liver, including the biomarkers that are very typical of MASH in different stages, and then see what the difference will be between the entrance into the trial and the exit at 16 weeks. That's the first step is to validate that this molecule can be quite competitive as a once-a-week therapy for both the weight loss as well as improvements in the status of MASH, determined by biomarkers. Based on that, then we will decide on whether we go to a full-fledged phase II to prove the tolerability and efficacy of the drug. Gary, do you want to take the 2001 question about indications and partnerships?
Yeah, I think you mean MDX3001 for the in vivo CAR-T program, if I understood the question correctly. For MDX3001, our initial thought is that we would pursue studies in autoimmune disease. There, the targeting that we would be looking for would be to B cells. We would be looking to deplete normal B cells in patients who have autoimmune disease and look in a diverse range of autoimmune diseases as well. The CD19 CAR that's encoded by the mRNA in the antibody-targeted LNP would, of course, be the mechanism by which we would achieve that, and we have very convincing preclinical data, both in non-human primate models as well as in humanized mouse models, that those cells can be depleted in both the blood and in tissues.
We would hope to be doing the same in patients either late this year or early next year when we have completed production. In terms of partners, we are actively looking to partner with big pharma. What we're looking for in a partnership are really someone who can help us move the product into the clinic and patients who would benefit from the treatment. This would require, first and foremost, interest and expertise in the area of autoimmune disease. This technology is applicable to a wide range of different clinical targets, including oncology, including some antiviral applications, and a variety of inflammatory conditions. We'd be looking to people who have expertise there, both commercially and in addition, scientifically and medically in terms of understanding the pharmacokinetics, the dose response relationships, and the regulatory pathways in those indications.
We are having discussions, but are at the early phases of those discussions presently.
Great. Thank you. The next question will come from Edward Tenthoff with Piper Sandler.
Please go ahead. Great. Thank you very much.
I'm really excited to hear about all the progress with the pipeline, in particular, excited about the in vivo CAR-T. I think that could be really differentiated. I wanted to ask about the MDX2001 data, I think you mentioned head and neck, lung, and another indication. It looks like maybe that data was pushed out to the first half of 2027. Can you give us a sense of what's going on with enrollment there? Is there one indication that's enrolling more patients? How many are you intending to enroll altogether in that phase I study?
Gary, you want to take that?
Sure. Yeah. The initial studies that were performed with MDX2001 were really performed to demonstrate both the safety, the pharmacokinetics, and the immunogenicity. For the very first part of those studies, we were taking all comers, regardless of where we thought the drug might eventually be useful in the clinic. This was really mostly to get into a range where we could expect to see efficacy. At that point, where we think we're starting to get efficacy, that's the point where we will switch into the specific tumor targets. To date, we've enrolled 39 patients in MDX2001, and the data that we're looking at would lead us to think that we are getting to ranges where we're seeing biologic effects in vivo.
I think we are now thinking more actively about recruiting the kinds of patients you're talking about who have tumors that we think are more likely to respond to the immunotherapy. There was a list of about 13 different malignancies that both bear Trop-2 and c-Met. We, for various reasons, are starting to narrow down ones where we think it would be more likely to see a response. I think that non-small cell lung cancer would be very high on that list. We think perhaps some types of renal carcinomas would be high on that list. We think there's a possibility that other solid tumors, like, for example, ovarian, might be something worth exploring. We will focus our next efforts on that.
We also are going to be exploring, while we're testing IV administration, we will be planning to also look at subcutaneous injection, which might allow us to go to higher dose with good tolerability, and which is, as you know, much more patient friendly. All of those are ongoing. With regard to your question of how many more patients, that's a bit hard to know because we're really at the signal-seeking stage. I think it's more likely it's going to be in the tens, a multiple of 10, not multiples of 100, but we'll follow the data.
Great. That's super helpful, Gary. Appreciate it. Sure. The next question will come from Kevin DeGeeter with Ladenburg Thalmann.
Please go ahead. Yeah. Thanks for taking our questions.
On 2003, can you just walk us through the strategy there with regard to, I guess, potential timing of the phase I data? I think you called out autoimmune for potential development moving forward, post phase I. How are you thinking about prioritization in oncology versus autoimmune and maybe, clinical strategy in the autoimmune space on 2003?
Well, Gary, you're going to work today.
Well, you can chime in any point, Elias. 2003, our thinking about initial indications for 2003 are really in the area of lymphoma, B-cell lymphomas. In large measure, it's because that's an indication where there is clinical proof of concept. What we bring to the table with our new molecule is that in addition to the CD19, or actually in addition to the CD20 that is in successful products like Lifitimab, for example, we also can include CD19 so that the problem of immune escape, which is seen quite frequently with those molecules, can be addressed in ours.
We think that we're following a path that is significantly de-risked by prior clinical data, and we will move as quickly as we can through the dose escalation, initially intravenously, and then I think as Elias mentioned, also through the subcutaneous routes to follow on, and that will be our first priority. With regard to your question about autoimmunity, we remain quite interested in it, and I think there will probably be a phasing because the initial safety data that we get from the oncology studies will help us find a dose that is safe and likely to be effective in autoimmune disease. We're also leaving the door open to the possibility of maybe using another form of the molecule, one for oncology, one for autoimmunity, but that still builds on the basic premise.
Short answer to your question is oncology first, autoimmune disease second, and getting to obviously a therapeutic dose in as rapid a time as we can without compromising patient safety.
That's great. Thanks for taking our questions.
Your next question will come from Yale Jen with Laidlaw and Company. Please go ahead. Good afternoon.
Thanks for taking the questions. I just want to go back to AA006 in terms of MASH. What severity or what level of patients you are initially contemplate, whether that's F2-F4 or any specific F3, F4 level? Any comments, any thoughts on that?
Let me take that one. No, we're definitely looking at F2, F3 to start. Okay? As determined by composite biomarker panel, which has been validated, that people are using more and more. Informed by that, we will decide whether we'll go F3, F4, which is where the most unmet need is, and/or F2, F3, F4 or pre-cirrhosis F4, obviously. That's the thinking. Right now, we need to get the fundamental information about the behavior of this molecule in both normal volunteers and MASH patients of the categories F2, F3, more favoring F3. As you know, the recruitment of these studies can be challenged because there's a tremendous amount of studies going on. We will focus on F2, F3, which is easier to enroll.
Maybe just one more follow-up on the same molecule, which is that over longer terms, would you consider AA006 as a monotherapy, or you think that could be used as a combination with some other OPKO drug?
That's a great question. It goes back to the philosophy, the scientific basis of why we picked GLP-1 glucagon. You know that in the current situation, we know that there is Madrigal and the parahormone beta receptor approach, and then there is the three products, FGF21, the three companies that have launched their products and have been acquired. We know that FGF21 is definitely a validated target. The beauty of GLP-1 glucagon is that glucagon is upstream of FGF21. We've shown that when we use our molecule, there is an over an increase in levels of FGF21 triggered by glucagon, in addition to the effects that glucagon itself has. We think there is a synergy, but it's a synergy within the molecule, not a synergy by combining the two drugs.
We think that's one of the scientific reason why we are going forward with this trial, because we believe that we will see in the biomarkers that in fact, there is a sort of a synergistic action, and we will measure that. We will measure the levels of FGF21 before and after treatment so that we can actually demonstrate that there is a synergistic effect between the FGF21 pathway and the glucagon pathway, which are known to interact with each other. We have demonstrated in the preclinical studies that indeed our drug, compared to other drugs of the GLP-1 glucagon class, seems to have a significant effect on the FGF21 pathway. I hope that helps. Oh, absolutely.
Great. Thanks for the answers and congrats on the progress.
Again, if you have a question, please press star then one. Our next question will come from Michael Petusky with Barrington Research. Please go ahead. Hey, good evening, guys.
I guess I wanted to ask on 4Kscore, you guys have expressed some hopes that things could open up there with primary care docs and maybe some payer policy advancements, et cetera, new opportunities. I just wonder if you guys can speak to your expectations around any of that impacting second half, or is that more of a 2027, 2028? Can you just talk about sort of somewhat near term and then longer term expectations around the 4-K? Thanks. Hey, Mike, it's Adam.
I'll try. Oh, go ahead.
Go ahead, Adam. Oh, okay.
No, no, I was going to ask you to take it.
All right, great. 4K, we're still pending some of the confirmations from Medicare before we were to actively pursue some of those broader market opportunities. Reimbursement, broadly speaking, continues to go well. There's opportunities for improvement, we think until we hear definitively on the CMS approvals for changing the Medicare requirements, we're going to be cautious in the primary care space. We think there remains large opportunity. We think it's double-digit growth opportunities from a volume and reimbursement perspective. Should be a significant tailwind once that comes through. At this stage, it has not, so we would expect probably to be more of a 2027 and beyond impact.
Okay, great. Then sort of a follow-up, I think, on the lab business. Reduction in your estimate for cost and expenses. I didn't catch it if you said it. Is a meaningful part of that coming out of lab, or can you just speak to where that reduction is primarily coming from? Thanks. It is coming out of the diagnostics.
They're mostly tied to the earn-out payment that we received from Labcorp on the second closing that happened back in May. Beyond that, we've got some modest decreases coming, the majority of that came from the gain offset that came through.
Let me also say, in addition, we focused our efforts at increasing productivity on multiple vectors. One is the reduction in headcount. We're right now at 1,400. Correct me if I'm wrong, Adam, but low 1,400s. Which we started, if you go back two years, we were at 3,300. That relates to both efforts in efficiencies as well as the divestment of the outside of New York, New Jersey business and the oncology business. That's one. The second is really operationally, when you look at the test-by-test analysis, what we found is that we can reduce our costs by not doing some of the esoteric tests that are expensive and not in high demand. We basically partner that with significant partners who can do that at lower cost than we do. That's the second one. Then the footprint.
We've really looked at our patient service centers, we've relocated some of them, closed some of them. We're reorganizing our footprint in the New Jersey, New York area. Then we have also looked at using our resources in a more efficient way. For example, looking at clinical trials, we are now participating as a lab for clinical trial entities, CROs, that do phase I trials right now. Also, we've also been partners with entities that really look at samples. We've monetized, if you will, our ability to truly use what we call our leftover samples for purposes that relate to many demands by pharma companies and CRO companies for analyzing large-scale population data.
Those are the sort of vectors we're using, in addition to the operational efficiencies that you gain by locating and relook at your patient service center configuration, which reduces, as a consequence, your logistical costs.
Okay, great. That was super helpful. Could I sneak one more quick one in, just around NGENLA, the profit share? Adam, it feels like you guys are tracking behind guidance, you maintain guidance, and I'm just curious, I guess, your level of visibility and your confidence. Obviously, you've held guidance, so there's some level of confidence. I'm just curious, I guess, about the level of visibility in terms of the full-year expectation. Thanks. No problem. I think the NGENLA performance for the first half of the year was within exactly where we guided, and I think the full-year guide hold remains.
You'll remember that each year, the gross profit share resets on January 1st, and as the year progresses, the percentages and the amounts go up depending on the share of NGENLA compared to GENOTROPIN, as well as the growth of the overall franchise. The cyclical nature of that does weigh quite heavily on the second half of each year. We were quite pleased with the progress that Pfizer's made and feel like the gross profit share is precisely on track to the first-half guide, and we expect the full year to come in within that $34 million-$37 million guide.
Great. Thank you. Again, if you have a question, please press star then one.
Our next question will come from Yi Chen with H.C. Wainwright & Co. Please go ahead.
Thank you for taking my questions. I noticed that core diagnostic revenue had a small drop from second quarter 2025 to 2026. Your guidance for full-year 2026 service revenue also had a small drop compared to the guidance you gave during the first quarter financial results. Can you give us some additional color as to whether the diagnostic performance is meeting expectation?
I think there's a couple of things that drove the, I think it was about a $4 million drop on the top end and a $6 million drop on the top end of the revenue guide. That's primarily coming from some of the lines of business that Elias mentioned are taking a little longer to mature. They're still deeply in the pipeline, that slight adjustment down when we looked at the first half of the year and the mix that was coming through on the core business, saw that the mix was overall coming in strong, but some of those new revenue verticals were taking more time to come through than not. They're not significant revenue drivers in 2026, but they did have the primary driver to come down.
4K is also slightly behind our expectations, as we had expected some positive movement on the Novitas decision. That hasn't come true yet either. Overall, those are the drivers behind the guide. I'll say on the pharmaceutical product revenue, we did take that guide up. That business continues to perform well. RAYALDEE is ahead of our expectations as we stand now, and our operations in Spain, Mexico, and Chile remain quite strong and have expectations for improvement within our CDMO business in Ireland. Those are the main drivers behind the movements in the guide, both on the diagnostics business but also our pharmaceutical business.
Got it. Thank you. Regarding the molecule OPK8801001, you mentioned that it showed 24 greater growth hormone receptor intactness. Does that translate to lower dosing frequency or better tolerability? How does that affect your clinical development strategy? Thank you. Good question. The answer is yes.
This is what we're aiming for. These anti-growth hormone are given daily with injections. This one will be once a week. Definitely, in terms of comparing results based on the data we have, it is more efficacious. We believe that based on the data we presented, plus the fact that it's a once a week and really the demand is there, it's a significant demand in terms of finding more convenient ways of treating these patients with less safety issues. I think it's a product that I have a lot of hope for.
Got it. Thank you. This will conclude our question and answer session.
I would like to turn the conference back over to Dr. Philip Frost for any closing remarks. Please go ahead. Thanks for your questions, and above all, thanks for your interest in OPKO.
We look forward to speaking with you again at the end of the third quarter, and I'll leave you with have a good evening.
The conference has now concluded. Thank you for attending today's presentation.
