Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Thank you, Brian. And thank you all for joining us for our second quarter twenty twenty five earnings call. We made substantial progress in the second quarter, most notably with the announcement of positive top line results from our Phase 2b MAVIGATE clinical trial, our subsequent $400,000,000 financing and advancing our discussions with the FDA and BARDA regarding the further development of CD388. In an effort to keep today’s prepared remarks as succinct as possible, and given our current status as a non revenue generating company, we will not have a dedicated section to review our quarterly financial results on this call and will not repeat in detail information that which has been previously discussed. Rather, I will point you to the press release and 10 Q we filed earlier today.

With that, I will begin by reminding everyone that Sidera’s proprietary Cloudbreak platform enables the development of novel drug FC conjugates or DFCs, a fundamentally new class of drugs that combines the strengths of small molecules with those of monoclonal antibodies. Our lead asset CD388 is a once per flu season antiviral drug with universal activity against all flu strains and is designed to have universal activity in all people regardless of immune status. Its unique properties substantially enhance its antiviral activity, making it a potentially transformational universal preventative of influenza that overcomes the limitations of existing vaccines and antivirals. In late June, we announced the top line results from our navigate phase 2b study, which evaluated the efficacy and safety of a single administration of CD388 for the prevention of seasonal influenza in healthy adult subjects. The study was initiated the September and enrollment was completed with over 5,000 subjects in the December 2024 before the peak of the flu season.

Subjects were randomized across three CD388 dose groups and one placebo group. The primary analysis included all available data as of 04/30/2025. The Navigate study was designed initially to determine dose selection for the Phase three study and was not powered for statistical significance. Prior to study start, we’d expected based on historical flu season averages that two percent of participants in the placebo arm would develop influenza illness. However, as the twenty twenty four-twenty twenty five flu season unfolded, we updated this forecast and predicted that the placebo attack rate could be sufficiently high for the Navigate study to be powered for statistical significance.

Based on this updated forecast, we discussed and reached agreement with the FDA on modifications to the study’s statistical analysis plan to evaluate the potential statistical significance of CD388 efficacy versus placebo. The observed placebo attack rate in the NAVIGATE study was two point eight percent, which enabled the detection of a statistically significant difference from placebo for at each dose group. Single doses of four fifty milligrams, three hundred milligrams and one hundred and fifty milligrams of CD388 confer seventy six, sixty one and fifty eight percent protection respectively with P values of less than 0.001, zero point zero zero two four and zero point zero zero five at each dose respectively. This is remarkable given the relatively small size of the study compared to vaccine studies. Importantly, the prevention efficacy data for each of the CD388 dose groups exceeded the historical average vaccine effectiveness of approximately forty percent for a seasonal vaccine.

The safety and tolerability data were consistent with prior studies of CD388 and similar in all arms of this study with no safety signals observed. While we observed a clear dose response relationship for efficacy, there were no meaningful changes in safety across the dose groups and placebo. These and additional details of the full NAVIGATE top line results, including a replay of the data call are available on our website under the investors tab. We plan to present additional details from the NAVIGATE trial at upcoming scientific conferences later this year. We believe that these results are groundbreaking for the field of influenza and support our confidence in the potential of CD388 to offer robust once per season protection against influenza A and B.

Based on these robust data, we submitted our end of phase two meeting request to the FDA to review the data and discuss the details of a phase three study. This meeting has been scheduled for later this month. Once we have received the meeting minutes from the FDA, we plan to disclose key details of our planned Phase three study, including study design, dose selection and timelines. We have guided previously to initiate this study in the Southern Hemisphere in the 2026. Pending feedback from the FDA, we are confident that we can meet that goal.

But we are also operationally prepared to start the study this fall should this become an option based on the outcome or end of phase two meeting. If we are able to start phase three this fall, we believe that this study will enroll over the course of two flu seasons, the 2025, 2026 Northern Hemisphere and the subsequent 2026 Southern Hemisphere flu season. Following the initial flu season, we plan to conduct an interim analysis for potential trial resizing. In phase three, we plan to focus our efforts initially on large populations with the highest unmet need, which includes high risk comorbid and immune compromised patients, because they are disproportionately affected by influenza as evidenced by substantially higher rates of hospitalizations and deaths and are underserved by currently available vaccines and antiviral drugs. Our plan to address these high unmet need populations is the basis for CD388’s current fast track and priority review designations.

In addition, based on the strength of the Phase 2b results, we have submitted to the FDA an application for breakthrough therapy designation and expect to hear the outcome of this application later this year. I would also add that we have submitted a proposal to BARDA, which if funded could provide meaningful funding to support manufacturing and additional clinical development studies of CD388. We expect to learn the outcome of this submission also by the end of this year. As we prepare to advance CD388 into Phase three, we do so from a position of significant financial strength, having recently closed an upsized public offering for gross proceeds of $402,500,000, which provides funding through the completion of our planned Phase three study. This funding also enables us to conduct additional supportive clinical and non clinical studies, as well as additional market research to further characterize the cost effectiveness and commercial opportunities for CD388, both in The US and Ex US.

This includes work to highlight the burden of illness that influenza represents in our initial target population and the cost offsets that could potentially be achieved with CD388. We plan to present the results of these activities in the coming months, following the conclusion of our discussions with the FDA regarding our Phase three plans. In closing, the data we have generated to date further validate our Cloudbreak DFC platform and the potential of CD388 to offer universal protection against both seasonal and pandemic influenza strains. While vaccines play a vital role in flu prevention, they do not offer sufficient protection, particularly for immune compromised individuals, underscoring the need for a durable, broadly acting antiviral like CD388. We look forward to discussing our plan Phase three study design and trial start timeframe with the FDA shortly.

With that, I will turn it back to the operator to take your questions.

Conference Operator: Thank you. We will now begin the question and answer session. Our first question is from Seamus Fernandez with Guggenheim Securities. Please go ahead.

Seamus Fernandez, Analyst, Guggenheim Securities: Great. Thanks so much for the question. So just wanted to see if you can help us understand potential differences from the Type C meeting that you had with FDA and the planned Phase III design that you shared with us during your Analyst Day, if there are any potential changes or meaningful changes that you’re proposing or if you’re simply looking for your pre phase three discussion to just clarify those particular points from the Type C meeting. And then just as a follow-up question on BARDA, I was hoping to get a better understanding of exactly what you would hope to achieve with the grant. I don’t know if that’s something that you can discuss at this point, but I think we have some idea.

But it would be interesting to just hear how that exercise is advancing and what the prospects might be for BARDA. The last question that I have is, would that evolve to potentially become something that that could incorporate orders? It’s unclear if the administration is is currently concerned about bird flu or or other influenza spreading, but just interested to know what it takes to kind of move forward to to actually get to orders, should the BARDA grant be issued? Thanks so much.

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Sure, Jonas. I’ll provide some initial responses and then I’ll welcome Nicole Dafarpana to supplement. So regarding our upcoming meeting with the FDA, and regards to your question, you know, with the difference from the Type C meeting, we don’t have expectation of substantial differences. We largely reached alignment with the FDA in our Type C meeting in our discussions regarding the Phase three plan. The difference is that meeting took place in May before the Navigate Phase 2B results were available.

Now that we have the results, this is the first opportunity to discuss those results within the context of the Phase three plan. Obviously, based on the strength of the Phase three data, and the strong safety that we observed, We don’t anticipate substantial differences from that discussion. Regarding BARDA, the plan, as you are aware, when you submit these there is a base period and option period. We have, expectations that the base period will, if funded, would, fund manufacturing, in particular the onshoring of manufacturing to The US. Then there are various options for the, option period that which exercised could, result in substantial funding to support additional clinical studies.

And then finally, regarding, any orders from BARDA, that would, come in the form of emergency use authorization in the event of a bird flu outbreak. We believe that based on the strength of the Phase 2b results, that would be an option should there be an outbreak. I would not, anticipate a stocking order for CD388 in the absence of an emergency use authorization, however. So, I’ll invite Nicole to provide any additional color on those questions. Nicole?

Dr. Nicole Darbhapana, Chief Medical Officer, Sidera Therapeutics: Thank you, Jeff. I think you captured it quite nicely. And hello, Seamus. I think going back to the first point, had a as Jeff mentioned, we had a significant amount of alignment with the FDA on our trial population, the study design and endpoints. Of course, that was before the benefit of having this nice phase two data.

So, we will then have this meeting currently to kind of align with them further in case there’s any changes, which we do not anticipate to the study design. Once we have received the meeting minutes, we will share openly any changes that have potentially been made.

Frank Karbaugh, Chief Financial Officer, Sidera Therapeutics: Great, thanks so much.

Conference Operator: The next question is from Eric Schmidt with Cantor Fitzgerald. Please go ahead.

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Thanks for taking my question. Congrats on a just a wonderful second quarter. Maybe just to continue Seamus’ line of discussion around the upcoming FDA meeting. I assume first it’s in August because I think you need to schedule those within sixty days. So you can correct me if my timelines are off.

But how would you plan to update investors on the outcome from that meeting? What actual points of discussion or questioning do you plan to put forth to the FDA? And then do you also plan to submit for a commissioner voucher? Would seem that CD388 might be a good fit for a national priority. Thank you.

Sure, Eric. All good questions. As discussed in the response to Seamus’s question regarding the FDA meeting, this is the first opportunity really to discuss with them the phase three plan in the context of the phase 2b data. That meeting has been scheduled and we expect that it will occur by the end of this month. In response to your question about communication of the outcome that meeting, we will await the receipt of the FDA minutes and then communicate those results and the results of those minutes in detail.

With respect to your other question, I think you about the, CMTV voucher. We have submitted a, statement of interest to, it was a three fifty word statement of interest, and, we have yet to, receive a response. I agree that, CD388 would appear to be a very good fit. And was there another question, Eric, that I missed? I think you got it.

Unless you’re willing, Jeff, to talk a little bit more about what you want to hear from the agency in your pre phase three meeting before having a go decision on this season. Yeah, and again, I’ll respond and I’ll invite Nicole to provide any other color. Really it’s to corroborate the agreement we reached in our Type C meeting. So we haven’t disclosed the details of that because obviously that can change based on in the Phase two meeting. So, we will discuss those results, when they become available in the form of the meeting minutes from the FDA.

We don’t anticipate substantial changes because the results of a Navigate study were pretty much in alignment with the expectations that we discussed with the FDA in the Type C meeting. Nicole, any other color you would like to add to that?

Dr. Nicole Darbhapana, Chief Medical Officer, Sidera Therapeutics: Thank you, Jeff. No, nothing further to add.

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Thank you very much both.

Conference Operator: The next question is from Brian Abraham with RBC. Please go ahead.

Eric Schmidt, Analyst, Cantor Fitzgerald: Hi, everyone. Thanks for taking our questions. This is Nevin on for Brian. So just wanted to follow-up on a little bit more on the phase three design that you proposed. So you’re planning to enroll a more immunocompromised high risk population.

So could there be a greater chance that the trial could reach the needed number of events earlier than the Navigate trial had reached those events? And can you explain some of the reasoning behind enrolling the trial over two to three influenza seasons, just the one season after the NAVIGATE trial? And then could you also remind us on the evidence that you’ve generated to date that suggests three eighty eight can be redosed? And then do you imagine that regulators would want to see redosing potentially in the pivotal trial?

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Sure, yeah. Good questions. Can you repeat the first question, please?

Eric Schmidt, Analyst, Cantor Fitzgerald: Yeah, of course. Just given that the population that you’re planning to enroll is more immunocompromised and high risk. Do you think that there’s a greater chance that the trial could reach that the needed number of events sooner than the NAVIGATE trial had?

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Great question. Actually, we believe the opposite that the attack rate in the placebo arm of this study will be lower than that in the Phase 2b. And the main reason for that is even though and I think what your question was alluding to is that this is a more vulnerable patient population at the same time, they are more protected patient population. And so they go because of the inadequacy of vaccines and protecting, these patients, they are highly protected. Also a big difference is that, we believe that, at least half, if not more of these subjects will be vaccinated.

Even though the vaccine effectiveness will be modest at best, it does offer some protection. In regard to your other question on redosing, yes, we do, anticipate, conducting a redosing study that is planned. And it’s basically a continuation of, redosing that we had conducted in our first phase one study, where we are looking for anti drug antibodies. We didn’t see any substantial evidence of that. We also looked for those in the phase 2b study, but we have this great resource, in the subjects we enrolled in the navigate phase 2b study that have received a dose of three different doses of CD388.

So So we’re gonna take advantage of that resource and take a subset of those subjects for a redosing study that we anticipate starting shortly.

Eric Schmidt, Analyst, Cantor Fitzgerald: Okay, thank you so much. And then what do you think the timelines for that would be? Would that be kind of prior to the initiation of the pivotal trial or just

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Yeah, will, yeah, question. We’ll communicate that after we receive the meeting minutes from our upcoming end of phase two meeting, because we’ll be discussing that with the FDA.

Eric Schmidt, Analyst, Cantor Fitzgerald: Okay, great. Thank you so

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: much. Sure.

Conference Operator: The next question is from Joseph Stringer with Needham and Company. Please go ahead.

Eddie, Analyst, Needham and Company: Good afternoon. This is Eddie on for Joey. Thanks for taking our questions. Just two from us. First, just kind of a follow-up on the previous question.

Wondering what assumptions are built into that cash runway? And does this include that redosing trial as well as the potential for a second Phase three trial? And then a follow-up, just looking at the landscape, Sanofi guided for mid teen percent decline in their food business this year, probably due to The U. S. Pricing pressures.

Just curious what’s their what read through might be possible for your business and maybe some commercial outlook for CD388?

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Sure. For the first question on cash runway, let me turn that one over to Frank Carva, our CFO. Frank?

Frank Karbaugh, Chief Financial Officer, Sidera Therapeutics: Yeah, sure. Hey, Eddie. So look, with the $500

Frank Carva, Chief Financial Officer, Sidera Therapeutics: plus million in cash on hand now, we believe we are adequately funded through the end of our Phase III program, including the additional studies that we have cited here on this call, and also including different potential scenarios, how the Phase III could play out.

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: And then with respect to the second question, if you could repeat that. I know it was a commercial question regarding a Sanofi product, and I will turn that over to Jim Vital, our Chief Business Officer. So if you could repeat that question first.

Eddie, Analyst, Needham and Company: Yeah, absolutely. Just on Sanofi’s earnings call, they guided for a mid teen percent declines this year in their group business. And just seeing if there’s any read through to your business or commercial outlook for CD388?

Jim Beitel, Chief Business Officer, Sidera Therapeutics: Jim, thanks for the question. Yeah, appreciate the question and certainly there’s been a lot of downward pressure on vaccine businesses. I think not just Sanofi’s, but others as well. And a lot of that has to do with things unrelated to CD388 and I think it underscores the importance of our commercial strategy and development strategy, really focusing in on these subjects with the greatest risk. And there the burden of illness is highest and the value proposition that we’ve demonstrated in the NAVIGATE study and intend to demonstrate in the phase three, I think really brings something unique to the marketplace.

And so certainly downward pressure on vaccines, but a very different commercial model there relative to the one that we’re considering for CD388.

Eddie, Analyst, Needham and Company: Okay, thanks so much.

Conference Operator: The next question is for Roy Buchanan with Citizens. Please go ahead.

Brian Ritchie, LifeSci Advisors Representative, LifeSci Advisors0: Hey, great. Thanks for taking the question. Just a couple of quick ones. Guess you mentioned the scientific presentations later this year. Have you been accepted at any conferences?

And could you tell us what those are and any key data that we should be looking out for? For example, you going to have the ADA data from the Phase 2b there?

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Yes, good questions. We have submitted to the ISIRV and IDWeek. And Les, do you want to provide a little color on whether those have been accepted yet? I don’t believe they have, but we have high expectations that they will be accepted. Les?

Frank Karbaugh, Chief Financial Officer, Sidera Therapeutics: Sure, Jeff. And hi Roy. Yeah, we have two abstracts, are submitting two abstracts to ISIRB, one to summarize the Phase 2b data and another that has been accepted for a present, an oral presentation, and that’s going to be on our activity against a contemporary H5N1 strain, a non clinical ferret efficacy model, where we demonstrated robust efficacy At at as we, in the fall, we will also be presenting we’ve submitted an abstract to where we’re gonna be describing the PKPD relationships for activity in

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: the Phase 2b trial with CD388.

Brian Ritchie, LifeSci Advisors Representative, LifeSci Advisors0: Okay, great. And then apologies for the non CD388 question, keep it quick. But I’m just curious what’s next in your view in terms of targets and potential timing when we might see some developments there? Thanks.

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Sure. Yeah, no specific plans at the moment. Certainly our oncology program is a great asset and we have an opportunity to advance that, but we have not determined a specific timeframe when we will be advancing that into the clinic.

Brian Ritchie, LifeSci Advisors Representative, LifeSci Advisors0: Okay, perfect. Thank you.

Conference Operator: The next question is from Sarah Nick with H. C. Wainwright. Please go ahead.

Dr. Nicole Darbhapana, Chief Medical Officer, Sidera Therapeutics: Hi, and thanks for taking the question. Just kind of following up on the previous one, wanted to get a sense of the resolution of the kind of data you’ll be presenting at these conferences. You mentioned some PK data. Will you be presenting anything with regards to individual subgroup data at these meetings, maybe with regards to age or region preventative efficacy outcomes or anything along those lines? Thank you.

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Yeah, we will be sharing the details of that when they are accepted. But certainly what you mentioned is encompassed in some of the abstracts that have been submitted. Les, any other color you’d like to share on that?

Frank Karbaugh, Chief Financial Officer, Sidera Therapeutics: Hi, Sarah. No, Jeff, you covered it well. Once the abstracts are published, we’ll be able to provide more clarity on what will be presented.

Dr. Nicole Darbhapana, Chief Medical Officer, Sidera Therapeutics: All right. Great. Thank you.

Conference Operator: This concludes the question and answer session. I’d like to turn the conference back over to Doctor. Jeff Stein for any closing remarks.

Dr. Jeff Stein, President and Chief Executive Officer, Sidera Therapeutics: Well, thank you all for joining us today. We greatly appreciate your interest in Sidera and hope you enjoy your evening. Thank you.

Conference Operator: The conference is now concluded. Thank you for attending today’s presentation. You may disconnect.
