Thane Weddig, Chief Executive Officer
Thank you, Gaia. Good afternoon everyone and welcome to our second quarter 2026 earnings call. On today's call I will provide an update on the important progress we have made across our clinical portfolio. First, with FG3246, our potential first-in-class antibody-drug conjugate targeting CD46 and its companion PET imaging agent in metastatic castration-resistant prostate cancer, and second, with roxadustat, our potential treatment for anemia due to lower-risk myelodysplastic syndromes.
Then David DeLucia, our CFO, will review the financials, after which we will open the call for your questions. Starting with slide 3, I'd like to highlight our mid- and late-stage programs and upcoming catalysts. The Phase 2 monotherapy trial for FG3246 and its companion diagnostic FG3180 in the post-ARPI, pre-chemo setting in metastatic castration-resistant prostate cancer continues to actively enroll patients, and we are on track for the results from the interim analysis in the fourth quarter of this year.
With our roxadustat program, the protocol for the Phase 3 trial has been finalized and we are advancing towards our goal of initiating the registrational trial in the fourth quarter of 2026. With a simplified capital structure and cash runway into 2028, we remain committed to executing on our strategic vision and look forward to the upcoming catalysts for both clinical programs. Let's start with the FG3246 and FG3180 program in mCRPC. The unmet need for new treatments for the 65,000 men in the U.S. diagnosed every year with drug-treatable castration-resistant metastatic disease is substantial. Targeting CD46, a novel tumor-selective multifunctional epitope that helps tumors evade complement-dependent cytotoxicity, could help address this need. Moving to slide 5, what sets CD46 apart from non-PSMA tumor antigen targets for metastatic prostate cancer centers on four key points. First, it is highly expressed in prostate cancer and other tumors, yet with limited expression in normal tissue.
Second, CD46 is upregulated during tumorigenesis as well as during the progression from localized castration-sensitive prostate cancer to metastatic castration-resistant prostate cancer. Third, an estimated 50% to 70% of patients have high CD46-expressing tumors. And finally, relative to PSMA, CD46 expression is more uniform with lower interpatient variability and with higher median expression in mCRPC tissues, which make it a compelling non-PSMA therapeutic target.
Slide 6 highlights FG3246, our CD46-targeting potential first-in-class ADC, which combines the YS5 antibody with an MMAE payload. MMAE is the payload for five currently marketed ADCs that generated approximately $5 billion in worldwide revenue in 2025, making it a well-characterized therapeutic approach for treating solid tumors. The YS5 antibody offers an androgen receptor–agnostic and non-PSMA approach, differentiating it from many of the prostate cancer treatments currently in development.
As with the ADC, our companion imaging agent, FG3180, utilizes the same YS5-targeting antibody and is being developed under its own IND. We believe that having a patient selection biomarker could enable us to potentially enrich the patient population in a Phase 3 trial while also differentiating FG3246 in the prostate cancer treatment paradigm. It also represents an important commercial opportunity as a companion diagnostic to FG3246, similar to the existing PSMA PET agents, which generated revenue of almost $2 billion in 2025.
FG3180 is an important part of our ongoing Phase 2 trial, where we will assess the correlation between CD46 expression, as measured by the PET agent, and response to FG3246. Our aim is a clinically differentiated therapeutic in a competitive yet highly unsatisfied mCRPC market. Importantly, we are the only non-PSMA program in mid- to late-stage development that combines a therapeutic with a companion PET imaging agent. The excitement we have in this program comes from the clinical results for FG3246 across two distinct trials.
We believe these results, summarized on slide 7, are competitive when compared to other approved and investigational treatments. In the Phase 1 monotherapy trial highlighted on the left part of the slide, FG3246 demonstrated a median rPFS of 8.7 months in patients with mCRPC who were heavily pretreated and were not biomarker-selected, with a PSA50 response of 36%. Twenty percent of the 25 RECIST-evaluable patients achieved an ORR with a meaningful duration of response of 7.5 months.
It is important to note that all of these ORRs were demonstrated at the 2.7 mg per kg adjusted body weight dose, utilizing the expansion phase of the trial, providing early evidence of a dose–response relationship in the top-line results. From the Phase 1b/2 investigator-initiated study at UCSF summarized on the right side, the combination of FG3246 with enzalutamide demonstrated encouraging antitumor activity with 7 months of median radiographic progression-free survival in biomarker-unselected patients across the entire cohort of 44 patients.
Importantly, in patients who had progressed on only one prior ARPI, the combination of FG3246 and enzalutamide achieved a meaningful median rPFS of 10.1 months with a PSA50 response of 40%. In addition to the efficacy measures, the IST provided us with important insights into the adverse event profile of the ADC. The use of G-CSF prophylaxis led to a significant decrease in grade 3 or greater neutropenia compared to the Phase 1 monotherapy trial.
This approach is now designed into our ongoing Phase 2 monotherapy study, where our objective is to keep more patients on their initial dose without the same degree of dose interruption or reduction experienced in the Phase 1 monotherapy trial, with the aim to build upon the 8.7 months of rPFS demonstrated in the Phase 1 trial. Moving to slide 8, an additional insight we gained from the IST is that higher tumor uptake of FG3180 was associated with greater PSA50 response.
The PET imaging on the right is from a patient with clear and meaningful expression of CD46 after exposure to FG3180. The bottom row of the table on the left shows that patients with a higher average maximum standardized uptake value, or SUV, of a target lesion when normalized to the SUV of the blood pool demonstrated a trend to greater PSA50 response to FG3246 versus those with a lower SUV, with a nominal p-value that just missed being statistically significant despite the small number of patients.
This is the first observed association between CD46 expression and response to FG3246. We aim to further characterize this association as part of the ongoing Phase 2 monotherapy trial. Slide 9 lays out the design for this Phase 2 monotherapy trial, where we will enroll 75 patients in the post–1 ARPI, pre-chemo setting across three dose levels, with the primary objective to select the optimal Phase 3 dose based on efficacy, safety, and PK measures.
All patients in the study will be treated with FG3180 in order to further explore the correlation between CD46 expression and response to the ADC in this biomarker-unselected trial. The interim analysis of this open-label trial is on track for the fourth quarter of this year and will include PSA50 response, ORR, safety, PK, and exposure–response data. Futility will be assessed by a composite response rate of PSA50 and ORR. Importantly, we expect mature rPFS data to become available throughout 2027 as patients continue their treatment with FG3246 and the trial progresses toward completion.
On slide 10, we'd like to emphasize the three design elements we have incorporated with the aim of improving upon the 8.7 months of median rPFS demonstrated in the Phase 1 trial. First, we are testing three of the highest doses from the Phase 1 monotherapy study: 1.8, 2.4, and 2.7 milligrams per kilogram. Second, primary prophylaxis with G-CSF is being utilized to mitigate neutropenia, an approach which was successfully implemented in the Phase 2 portion of the IST.
We believe reducing the incidence of grade 3 or greater neutropenia should lead to fewer dose interruptions or adjustments, extending the duration of therapy and enabling more consistent exposure to the ADC FG3246. And third, we are enrolling patients who are earlier in the progression of mCRPC versus the median five prior lines of therapy in the Phase 1 trial. The 10.1 months of median rPFS demonstrated in the IST in patients who progressed on only one prior ARPI underscores the potential of FG3246 in this patient population.
Together, we believe these design elements have the potential to improve upon the Phase 1 results and achieve a median rPFS of 10 months or greater, which can be viewed as the threshold for commercial competitiveness. Slide 10 shows the sites who are participating in the ongoing Phase 2 trial. We now have 23 sites live at top-tier U.S. institutions, and we continue to be encouraged by our progress to date. We remain on track for the interim analysis of 36 patients in the fourth quarter of this year.
To conclude this update on FG3246, we are actively enrolling patients in our Phase 2 monotherapy trial in the post–1 ARPI, pre-chemo mCRPC setting, with important design elements in place that we believe could enable FG3246 to surpass the 8.7 months of median rPFS demonstrated in the Phase 1 trial. We look forward to the interim analysis in the fourth quarter of this year. Moving on to the roxadustat lower-risk myelodysplastic syndromes program on slide 13.
There are approximately 50,000 patients with anemia associated with lower-risk MDS in the U.S., with current therapies effective in less than 50% of these patients. With no oral options currently on the market or in late-stage development, there's a significant opportunity for an effective, durable, convenient oral treatment that works across multiple lines of therapy. Slide 14 highlights why we believe roxadustat can be that treatment. In a post hoc analysis of high transfusion-burden patients from our previous Phase 3 MATTERHORN study, using the International Working Group definition for high transfusion burden of four or more RBC units in two consecutive eight-week periods, we saw that 36% of patients treated with roxadustat achieved transfusion independence for at least eight straight weeks versus only 7% in the placebo group, with a nominal p-value of 0.041.
These results are highly similar to the pivotal trial results for the two most recently approved therapies for anemia associated with lower-risk MDS. Turning to slide 15, based on these results, our target indication is intended to be for the treatment of anemia in patients with lower-risk MDS who are refractory to or ineligible for prior ESA treatment. Where we believe roxadustat can raise the standard of care across multiple lines of treatment, we believe we also have a unique opportunity to demonstrate transfusion independence across both RS-positive and RS-negative patients, as presented in our most recent disclosure at EHA, the European Hematology Association. In a post hoc analysis of the Phase 3 MATTERHORN study, roxadustat demonstrated similar rates of transfusion independence across both RS-positive and RS-negative patients. Primary research that we have conducted with practicing clinicians indicates that roxadustat has the potential to be a useful treatment in both of these patient segments. The RS-negative opportunity, which represents a majority of lower-risk MDS patients, is especially relevant given luspatercept, the market-leading brand in the treatment of lower-risk MDS, has not demonstrated clinically differentiated efficacy in this segment of the lower-risk MDS population and is not indicated for use in the second-line setting in RS-negative patients. We believe that demonstrating similar efficacy across the entire patient population could position roxadustat favorably in the treatment paradigm of lower-risk MDS. Slide 16 provides an overview of the Phase 3 trial. Following our interactions with the FDA, we have now finalized the protocol for the Phase 3 study, which includes a primary endpoint of eight-week transfusion independence over the first 24 weeks of the trial, with key secondary endpoints of 12-, 16-, and 24-week transfusion independence over 48 weeks.
We continue to explore the opportunity to develop roxadustat internally or with a strategic partner, which aligns with our goal of initiating the study in the fourth quarter of 2026. To summarize the roxadustat opportunity in lower-risk MDS on slide 17: with a substantial unmet need, no oral therapeutic options on the market or in late development, significant potential in RS-negative patients, and an orphan drug designation in hand, we see roxadustat as a compelling commercial opportunity.
We've continued to make important progress with the Phase 3–enabling activities. With that, I will now turn the call over to Dave to discuss the company's financials. Dave?
David DeLucia, Chief Financial Officer
Thank you, Thane. For the second quarter of 2026, total revenue was negative $1.5 million, compared to $1.3 million for the same period in 2025. Total operating costs and expenses for the second quarter of 2026 were $16.1 million, compared to $13.4 million for the second quarter of 2025. R&D expenses for the second quarter of 2026 were $6.8 million, compared to $5.9 million in the second quarter of 2025. SG&A expenses for the second quarter of 2026 were $9.3 million, compared to $7.1 million in the second quarter of 2025.
During the second quarter of 2026, we recorded a net income from continuing operations of $12 million, or $2.96 net income per basic and diluted share, compared to a net loss of $13.7 million, or $3.38 net loss per basic and diluted share one year ago. Now, shifting towards cash. As of June 30, we reported $95.7 million in cash, cash equivalents, investments, and accounts receivable. We expect the company to have a cash runway into 2028, enabling us to continue to invest in our U.S. pipeline opportunities. Thank you. And I will now turn the call back over to Thane.
Thane Weddig, Chief Executive Officer
Thank you, Dave. We entered the second half of 2026 with promising momentum. We will continue our disciplined execution of the FG3246 and FG3180 programs, with results from the interim analysis of the Phase 2 monotherapy trial expected in the fourth quarter of 2026, and continue the Phase 3–enabling activities for roxadustat, with the goal of initiating the Phase 3 trial in lower-risk MDS in 4Q26. With that, I would now like to turn the call over to the operator for Q&A.
OPERATOR (Operator)
Certainly. As a reminder, to ask a question, please press star-11 on your telephone and wait for your name to be announced. To withdraw your question, please press star-11 again. Please stand by while we compile our Q&A roster. Our first question will come from the line of Alex Ramsey of William Blair. Your line is open.
Alex Ramsey, Analyst at William Blair
Hi, this is Alex on for Andy. So, for the upcoming Phase 3 trial of roxadustat, the dosing regimen begins with 2.5 milligrams per kilogram with potential for titrating up to 3.5. So we're just wondering how that determination is made. And if it's based on tolerability or efficacy, how long after starting the treatment the assessment is made, and then also what the titration interval is from both a timing and a dosing perspective.
Thane Weddig, Chief Executive Officer
Thanks, Alex, for the question. I'm going to hand that question over to Carol Gadam, our VP of Product Development. Carol, thank you for the question.
Carol Gadam, VP of Product Development
So up-titration or down-titration is based on an assessment of benefit and risk, as you have highlighted. And a change in dose is possible every six weeks based on what we see from a benefit and risk perspective.
Alex Ramsey, Analyst at William Blair
Perfect. Thank you so much. And so that, is it straight from 2.5 to 3.5 if they go up in dose, or is there some interval in between?
Carol Gadam, VP of Product Development
There are some intervals in between. There are some intervals in between, yes.
Alex Ramsey, Analyst at William Blair
Okay, perfect. Thank you so much.
Thane Weddig, Chief Executive Officer
And Alex, there will be very specific guidance to the sites on the titration, either up or down, based upon a number of factors including hemoglobin level and the rate of rise of that hemoglobin level as well.
Alex Ramsey, Analyst at William Blair
Perfect. Thank you so much.
OPERATOR (Operator)
And our next question will be coming from the line of Matthew Keller of H.C. Wainwright. Your line is open.
Matthew Keller, Analyst at H.C. Wainwright
Hey, good afternoon everyone. Thanks for taking our questions. So I guess on the roxa program as well, first I was wondering if you'd remind us, you know, how contingent is starting the Phase 3 on a partner. And then a follow-up to that I was wondering is, you know, how has the MATTERHORN data changed your calculus at all on potentially partnering that program?
Thane Weddig, Chief Executive Officer
Hey, thanks, Matt, for the question. So, the start of the Phase 3, as we've stated previously, we are undergoing both the opportunity to develop internally as well as partner the program. To develop internally, we would have to bring in capital in order to do that, and so that's a consideration while we also evaluate strategic partners as well. And so we're running a parallel path with both of these. And at the end of the day, we're going to make the decision that we believe is in the best interest of shareholders.
And there are some dynamics in play related to economics. So if you think about the license that we wholly own in North America and South America, that was a license that was previously held by AstraZeneca during the development of the CKD program. When we negotiated those rights back from AZ, if we were to develop roxadustat on our own and commercialize on our own, we would owe AZ a mid-single-digit royalty on net sales. If we were to partner the program with a strategic, and somebody else were to develop and commercialize, AZ would then be entitled to 35% of any economics that would accrue to Kyntra Bio.
So that's one consideration from an economic perspective. Clearly, there are strategic and operational considerations that we continue to evaluate. And as I said, we're going to ultimately make the call that we believe is in the best interest of shareholders.
Matthew Keller, Analyst at H.C. Wainwright
Yeah, it totally makes sense. And then can you comment at all about how the RS data is maybe playing into that, if at all? And if I may, kind of an adjacent question, did the RS data also influence the potential Phase 3 design at all? Sorry, I'm going to pepper you with a couple there.
Thane Weddig, Chief Executive Officer
No, it's a great question. And so, the RS kind of dynamic, with respect to RS-positive and RS-negative, there's clearly a larger unmet need in the marketplace for RS-negative patients, given the fact that luspatercept has not been able to really show any sort of a benefit relative to ESAs in that particular patient population and the fact they're not indicated in the second-line setting for RS-negative patients. And so the understanding of that dynamic obviously plays into how we think about the opportunity, how we think about the clinical design, how we think about the ultimate forecast should we be successful in the Phase 3 trial.
We're going to make sure that we enroll the requisite number of both RS-positive and RS-negative patients in the Phase 3 trial so that we can have the power to be able to demonstrate that roxadustat works across both of those patient populations. But the RS-negative opportunity—or the MATTERHORN data—we'd be pursuing this regardless of the opportunity for roxadustat to perhaps show a differential benefit in RS-negative patients relative to RS-positive patients.
But it clearly does give us, we think, a really nice commercial opportunity across both segments, but especially in the RS-negative population, which makes up more than 50% of the total patients who have lower-risk myelodysplastic syndrome. Did that get your question, Matt?
Matthew Keller, Analyst at H.C. Wainwright
It absolutely did. Thank you so much for the color. I really appreciate it. And Dave or Carol, anything to add to that?
Carol Gadam, VP of Product Development
Thank you. The only thing I would add is you asked around how MATTERHORN informed the Phase 3, and it has obviously been a significant driver of the Phase 3 design. We went through a comprehensive analysis of what variables were driving outcomes—roxa versus placebo—and isolated transfusion burden as the key variable, and have designed the Phase 3 trial accordingly. And to Thane's point, the analysis also shows that roxadustat improves transfusion independence and hemoglobin across RS-positive and RS-negative, and so that is also reflected in the Phase 3.
Matthew Keller, Analyst at H.C. Wainwright
Makes sense. Thank you.
OPERATOR (Operator)
And our next question will be coming from the line of Michael King of Rodman and Renshaw LLC. Your line is open.
Michael King, Analyst at Rodman & Renshaw LLC
Thanks for taking the question, guys. If I could, I'd like to pivot to 3246 and 3180, a couple of questions on the program. I'm just curious how you guys look at it as far as, you know, I know it's one to two prior lines and one prior ARPI, but I'm just curious what you anticipate the enrollment might be for individuals who have been treated with lutetium-177, and whether you can enrich enrollment for that population. The reason I'm asking is I'm trying to think about whether there's any element of the design of the Phase 2 that could propel you towards some kind of an accelerated approval strategy.
Thane Weddig, Chief Executive Officer
Yeah, it's a great question, Mike, and I appreciate the question. I'll go ahead and kick it off, and then, Carol, I'll hand it over to you for additional commentary. So, to your point, we clearly are allowing prior Pluvicto-treated patients into the trial. At the outset of the trial we kind of had an estimate as it relates to what percent of patients were going to be previous Pluvicto-treated patients this far into the trial. While we're not disclosing our enrollment stats yet, what we can say is about 30% of patients who have been enrolled into the trial and randomized were previously treated with Pluvicto.
And we've got a pre-specified analysis based upon prior Pluvicto exposure or not, so that we've got that built into the SAP so that we will be able to clearly determine is there any sort of a differential impact or effect from 3246 based upon prior Pluvicto exposure. I haven't really thought about the ability to go for accelerated approval in that particular patient population if we showed a really nice benefit. But it's an interesting thought. Ultimately we're going to be data driven based upon the outcome of the phase two trial. Carol, go ahead.
Carol Gadam, VP of Product Development
No additions from my side.
Michael King, Analyst at Rodman & Renshaw LLC
I just wonder if has there been any inflection because I know it's early days, but Novartis just recently received first line indication, so I wonder if that 30% proportion might increase going forward from here.
Thane Weddig, Chief Executive Officer
Yeah, it very well could. I think what we found is that you don't see an immediate or instantaneous adoption, especially therapy where ARPIs have been really cemented as standard of care, both in the castration sensitive phase as well as if they haven't been previously treated with an ARPI in the castration resistant phase as well. So it's something we'll continue to keep an eye on. We're closely evaluating the patients who are enrolled to understand are we seeing an inflection in previously treated Pluvicto patients.
And so it's clearly an important consideration for us.
Carol Gadam, VP of Product Development
Yeah. And I would just add to that that there is obviously the dynamic around enrollment and that is obviously also highly driven by the sites in particular and the treatment practice at the individual sites. As we think about the design of a global phase three, we're obviously very closely monitoring market shares in the pre and CRPC setting and then the metastatic setting to understand eligibility criteria, but also how we set up the control arm and what is the appropriate prior line of therapy. So point well taken around there being a lot of movement in that space.
Michael King, Analyst at Rodman & Renshaw LLC
Yeah, yeah, yeah. Sorry to keep belaboring this point, but one other question I wanted to ask and that is I know PET imaging is your key, you know, guide towards response, but I'm wondering is it possible to get both pre and post treatment biopsy from these individuals? Because I'm just curious about expression, the levels of expression of PSMA prior to therapy and post therapy to see if there's any, you know, correlation or with the level of expression with PSMA, sort of.
Are you going to be more active serving the post PSMA setting, less active or, you know, indifferent to PSMA?
Thane Weddig, Chief Executive Officer
No. Thanks, Mike. Carol, you want to take that one?
Carol Gadam, VP of Product Development
Sure, yeah. It's certainly a very interesting scientific question and we're doing a lot in terms of tissue collection, PSMA scans, PET scans and our 3180 scans, as much as possible to understand how it evolves over time. As you can appreciate, there are limitations as to the burden that you can put on patients. So it is a bit more on a best effort basis, but it's certainly a key question to address. And what I would also just say is in this disease area, the tissue availability is limited given the disease often just being bone disease and also tissue availability if it's soft tissue disease. So we're coming up against some challenges here in terms of disease, but we're doing all we can to address that scientific question.
Michael King, Analyst at Rodman & Renshaw LLC
Well, I know the Prostate Cancer Working group just, you know, updated their guidelines to encourage the use of ctDNA. I don't know. Are you going to be looking at ctDNA in these patients,
Carol Gadam, VP of Product Development
Yes, we are. We definitely are. And in fact, in the phase one monotherapy trial, there was a really nice ctDNA effect with FG3246.
Michael King, Analyst at Rodman & Renshaw LLC
Okay. All right. I think I've exhausted my questions for now.
Thane Weddig, Chief Executive Officer
Thank you. I appreciate it, Mike.
OPERATOR (Operator)
And our next question will come from the line of Jay Olson of Oppenheimer. Your line is open, Jay.
Jay Olson, Analyst at Oppenheimer
Oh, hey, congrats on all the progress and thanks for taking our questions. We had a couple questions starting with 3246. Can you just talk about how you're thinking of positioning 3246 as a differentiated non-PSMA approach to metastatic CRPCs? Is the greatest opportunity in PSMA low or PSMA negative patients? Or do you see CD46 targeted therapy as potentially complementary to PSMA directed approaches? And then just on Roc, from a longer term perspective, how are you thinking about eventually moving into the first line setting?
Thank you. Sure.
Thane Weddig, Chief Executive Officer
Thanks, Jay. Good to hear from you. Carol, you want to take that one and then I'll add on?
Carol Gadam, VP of Product Development
Sure. Yeah. I think these are exactly the type of questions we're looking to address with the phase two. And that's why we're allowing prior lutetium to understand how responses are similar or different in different patients subpopulations. And to the prior question, we're also doing the scans to really understand where the patients fall and where there's the greatest unmet need and where we have the most compelling value proposition for 3180. So I think all strategic options are here on the table and it will ultimately will be data driven.
And then to your point around moving up lines, I think that's what we've traditionally seen right, is from the post chemo setting into the pre chemo setting into then the, into the hormone sensitive setting. And so those are certainly part of our life cycle considerations moving forward. Thane, back to you.
Thane Weddig, Chief Executive Officer
Yeah, thanks, Carol. And Jay, maybe one other comment, and this just comes from discussions with clinicians in this space. And this isn't based upon dozens of interviews like we would do as we were, as we would contemplate a phase three design. But this is in speaking with some KOLs, they believe that a PSMA approach will continue to be kind of standard of care in this pre chemo setting. What they also talk about is with the ARPIs, they're being used more in the castration sensitive phase and the clinicians are shying away from this ARPI switch approach just because you only get an incremental four to six months of additional rPFS when you switch from one ARPI to another. And so they think that the PSMA approach, like Pluvicto or other PSMA directed therapies, would be standard of care once a patient has progressed on an ARPI, once a patient then progresses on a PSMA directed therapy, then they tend to think about a different target, but they also tend to think about a different modality. So if they were on an RLT that targeted PSMA, they then might think about an ADC that targets a different epitope like CD46.
So they wouldn't go from an RLT that targets PSMA to an ADC that targets PSMA. They also may not go from an RLT that targets PSMA to an RLT that targets another epitope. And so, again, it's more anecdotal than anything. We'll continue to, as Carol said, explore it. It'll be heavily driven by what we see in our phase two trial. But, yeah, it's something that we think about a lot as we contemplate what a phase three design could look like.
Jay Olson, Analyst at Oppenheimer
Great. Thanks for taking the questions.
