Operator: Good afternoon and welcome to the Spero Therapeutics Full Yr 2023 Monetary Outcomes Convention Name. Presently, all contributors are in a listen-only mode. Following the corporate’s formal remarks, we’ll open the decision for questions. Please be suggested that this name is being recorded and a replay will likely be obtainable. You will discover info on the replay and additional info associated to as we speak’s bulletins on the Spero Therapeutics web site at sperotherapeutics.com. Presently, I want to flip the decision over to Michael Wooden, Managing Director of LifeSci Advisors. Mr. Wooden, please go forward.

Michael Wooden: Thanks, operator, and thanks all for taking part in as we speak’s convention name. This afternoon, Spero Therapeutics launched monetary outcomes and offered a enterprise replace for the fourth quarter and full 12 months 2023. Our press launch is offered on the Investor web page of the Spero Therapeutics web site. Earlier than we start, I might prefer to remind you that a number of the info offered on this convention name incorporates forward-looking statements primarily based on our present expectations, together with statements concerning the future improvement and commercialization of Tebipenem HBr, SPR720, SPR206, and the design, initiation, timing, progress and outcomes of the corporate’s preclinical research and scientific trials and its analysis and improvement packages.

These forward-looking statements communicate solely as of the date of this convention name, March 13, 2024. And the corporate undertakes no obligation to publicly replace any forward-looking statements or provide new info relating to the corporate after the date of this name. Taking part as we speak’s name are Sath Shukla, Chief Govt Officer; Dr. Kamal Hamed, Chief Medical Officer; and Esther Rajavelu, Chief Monetary and Chief Enterprise Officer. With that, I might like to show the decision over to Spero’s CEO, Sath Shukla. Sath, please go forward now.

Sath Shukla: Thanks, Michael. And I thanks all for becoming a member of us this afternoon. Spero had a really productive 2023 with progress throughout its portfolio of development-stage belongings. SPR720 is now within the newest levels of a proof-of-concept research in NTMPD, and we’re trying ahead to reporting top-line information, which we count on to do within the second half of this 12 months. The Section 3 scientific trial for Tebipenem HBr is up and operating. We not too long ago acquired IND clearance for SPR206 for the remedy of sufferers identified with hospital-acquired or ventilator-associated pneumonia. The corporate has a robust stability sheet with the monetary flexibility to execute on its plans. For me personally, 2023 was a very thrilling 12 months as I used to be honored to tackle the CEO position and to be supplied with the chance to guide a world-class group who share a imaginative and prescient to develop modern therapies to assist sufferers affected by critical infections and uncommon orphan illnesses. Let me start with SPR720, which we’re growing for nontuberculous mycobacterial pulmonary illness, or NTMPD. We’re growing SPR720 to be a first-line oral agent and imagine it has precisely the appropriate profile to deal with the unmet wants in NTMPD. NTMPD is a uncommon illness, however with a really well-identified affected person inhabitants of roughly 245,000 identified sufferers in developed markets. SPR720 is an oral drug with a novel mechanism of motion that isn’t exploited by different SOC brokers or these in improvement for NTMPD. Within the information we now have seen thus far, from accomplished in vitro and in vivo research, there was no proof of cross-resistance towards marketed antibiotics, and SPR720 has demonstrated a low propensity for collection of resistance. Now we have proven that it has efficiency towards a number of NTM pathogens and information help its potential for efficacy, security and tolerability, and macrophage penetration. SPR720 has additionally been granted orphan drug, QIDP and Quick Monitor designations. The objective of our Section 2a proof-of-concept scientific trial is to grasp SPR720’s exercise in NTMPD sufferers and to tell the design of a later stage and long run trial evaluating SPR720 together with present customary of care brokers. As a possible first-line oral agent, we imagine the industrial alternative for SPR720 is compelling. Kamal will present additional particulars on this program in a couple of minutes. Turning now to our companion packages, let me start with Tebipenem HBr, which is partnered with GSK. We’re growing Tebi as probably the primary oral carbapenem antibiotic for the remedy of difficult urinary tract infections, or CUTI. We had been happy to announce in January of this 12 months that the Section 3 PIVOT-PO scientific trial is now underway with the primary affected person, first go to, having occurred within the fourth quarter of 2023. Throughout 2023, Spero acquired written settlement from the U.S. FDA with a particular protocol evaluation, or SPA, on the design and dimension of PIVOT-PO. SPA usually represents a really excessive degree of concordance on the general protocol design between the FDA and a sponsor. So we imagine the regulatory side with respect to the design of this system have been de-risked considerably. Shifting on to SPR206, which is partnered with Pfizer (NYSE:) for European markets. We submitted an IND for a Section 2 scientific trial in HapMap sufferers, and not too long ago introduced that the IND has been cleared with the FDA. With that, I might now like handy the decision over to Dr. Kamal Hamed, who will present extra particulars on the scientific packages.

Kamal Hamed: Thanks, Sath. I’ll start with our SPR720 program, which we hope will ship the primary oral, first-line remedy for NTMPD. SPR720 is presently being evaluated in a Section 2a proof-of-concept scientific trial, and as Sath talked about, we’re trying ahead to sharing top-line information, which we count on to do within the second half of this 12 months. NTMPD is a debilitating uncommon infectious lung illness. There are presently no permitted first-line therapies, and the present customary of care is a chronic mixture routine of antibiotics, together with azithromycin, ethambutol, and rifampin. These have critical tolerability points and restricted effectiveness. The unmet want is for a remedy that has higher tolerability and effectiveness, fewer drug-drug interactions, in addition to shorter remedy length. We imagine that SPR-720 will meet these standards, and if permitted, has the potential to determine a brand new customary of care in NTMPD. The Section 2a scientific trial compares SPR720 monotherapy versus placebo. It’s designed to enroll as much as 35 sufferers who’re both remedy naive or remedy skilled, however would not have remedy refractory illness. We presently have 27 energetic websites which can be screening and enrolling sufferers. The first endpoint is microbiological response. Particularly, we’re measuring the slope change in sputum bacterial burden from baseline to day 56. Success on this endpoint would make SPR720 the one agent in improvement we’re conscious of to display early bactericidal exercise in sufferers with NTMPD. We imagine that the optimistic consequence with supportive proof from the trial secondary endpoints will allow us to maneuver confidently into late stage improvement. We’re engaged on extra improvement actions wanted to help SPR720’s development into late stage scientific research. These embrace ongoing toxicology work, CMC initiatives, and two Section 1 scientific research in wholesome volunteers presently underway. The primary, to evaluate intrapulmonary pharmacokinetics of SPR719, the energetic moiety of the prodrug SPR720 in a bronchoalveolar lavage research. This could give us a greater understanding of the extent of drug penetration into the lungs. The second is to guage the impact on the pharmacokinetics of SPR720 when co-administered with azithromycin and ethambutol. We count on to have outcomes from these research within the second half of this 12 months as effectively. Total, the continuing research are anticipated to offer us with a sturdy information set which will inform the registrational path for SPR720 as first line remedy for NTMPD. Now transferring on to tebipenem HBr. On January 2, we introduced first affected person, first go to in PIVOT-PO. The worldwide pivotal Section 3 scientific trial evaluating tebipenem-HBr in hospitalized grownup sufferers with difficult urinary tract infections, together with acute pyelonephritis. Sufferers are being randomized one-to-one to obtain tebipenem-HBr at a dose of 600 milligrams orally each six hours, or Imipenem-cilastin 500 milligrams intravenously each six hours for a complete of seven to 10 days. The first efficacy endpoint is general response, which is a composite of scientific and microbiological response, on the take a look at of remedy go to. The first evaluation for the trial, will likely be an evaluation of non-inferiority within the microbiological intention, to deal with inhabitants primarily based on a ten% non-inferiority margin. Goal enrollment will likely be roughly 2,648 sufferers with randomization stratified by age, baseline prognosis, i.e. cUTI or acute pyelonephritis, and the presence, or absence of urinary tract instrumentation. Enrollment is predicted, to be accomplished within the second half of 2025. Spero is liable for execution of the Section 3 scientific trial, and GSK will likely be liable for submitting the NDA. If permitted, tebipenem-HBr would enable for remedy of cUTI within the outpatient setting. It’s effectively established that sufferers and physicians typically want oral therapies, so we see tebipenem as a probably new and distinctive paradigm shift, from the present IV carbapenem customary of care, for methods to deal with pathogens related to cUTI. Lastly, to our SPR206 program, SPR206 is an investigational subsequent era polymyxin antibiotic, we’re growing to deal with multi-drug resistant gram-negative infections. SPR206 is designed, to disrupt the lipopolysaccharides, outer membrane and gram-negative micro organism, whereas lowering the nephrotoxicity potential of polymyxin. Primarily based on microbiological, and in vivo testing, we imagine that SPR206 has the potential to supply a broad spectrum of exercise, together with towards multi-drug resistant and extensively drug resistant strains. It additionally has potential, for an improved security profile, of diminished nephrotoxicity, in comparison with presently obtainable polymyxin. As Sath talked about, we introduced FDA clearance of the IND on February 28. With that, I will flip the decision over to Esther, to overview our quarterly monetary outcomes.

Esther Rajavelu: Thanks, Kamal, and good afternoon or night to all of you becoming a member of us on the decision as we speak. Spero is effectively capitalized with $76.3 million in money and money equivalents, as of December 31, 2023. As Sath talked about, in December, upon dosing of the primary affected person within the Section 3 PIVOT-PO scientific trial, Spero certified for $95 million in improvement milestones from GSK. It’s payable in 4 equal installments throughout 2024 and 2025, starting with the primary tranche of $23.8 million that we acquired within the first quarter of 2024. We estimate that our money and money equivalents, along with different non-dilutive funding commitments, will likely be adequate to fund our working bills, and capital expenditure necessities into late 2025. Now, transferring on to summarize our GAAP financials. Complete income for the fourth quarter of 2023 was $73.5 million, in contrast with whole income of $47.4 million for the fourth quarter of 2022.

Analysis and improvement bills for the 12 months ended December 31, ’23 had been $51.4 million in comparison with $47.6 million for the 12 months ended December 31, ’22. The will increase in analysis and improvement bills had been primarily attributable to elevated scientific exercise throughout the interval associated to our ongoing Section 2a scientific trial of SPR720. G&A bills for the fourth quarter of ’23 had been $6.4 million in comparison with $6.5 million of G&A bills for a similar interval in ’22. This year-over-year lower was primarily attributable to adjustments in personnel associated prices offset partially by elevated skilled and consulting charges throughout the interval. G&A bills for the 12 months ended December 31, ’23 had been $25.6 million in comparison with $36.5 million for the 12 months ended December 31, ’22. Primarily because of decreases in each personnel prices {and professional} and consulting charges.

And a internet loss for the total 12 months ended December 31, ’22 of $46.4 million or $1.23 loss per share of frequent inventory. For additional particulars on our monetary, please discuss with our 10-Ok filed with the SEC as we speak. With that, we’ll now open the decision for questions. Operator?

Operator: [Operator Instructions] Our first query is from Ritu Baral with TD Cowen. Please proceed together with your query.

Ritu Baral: Hello guys. Thanks for taking the query. Only a couple from me, however one in every of them after all is a bit difficult and should have a couple of components. One easy one, how is enrollment in 720 going, particularly with the halt of enrollment in a aggressive program? And my second query additionally has to do with 720. Particularly, I am to know extra concerning the 719 lavage research in wholesome volunteers. Speaking to KOLs, one of many issues round oral NTM compound is entry to the location of NTM an infection, particularly when a affected person has catheter illness. How do you guys consider perfusion and entry via the biofilm and type of simply location and exercise of the location of an infection? Thanks.

Sath Shukla: Ritu, thanks for the query. To your first merchandise on enrollment, we now have stated up to now that websites have been open, all 27 of them, and so they proceed to dose sufferers. And they’re persevering with to work in the direction of our steering of prime line information within the second half of this 12 months. To your second query, I will move it on to Kamal.

Kamal Hamed: Sure, good day, Ritu, and thanks for the query. By way of entry of the drug to the location of an infection, after all, these sufferers even have pulmonary hygiene as a part of the administration of this illness. And this additionally applies to inhaled remedy as a result of inhaled remedy might have drawback with distributing to the location of an infection. Nonetheless, we now have demonstrated within the hole fiber an infection mannequin, in addition to in non-human primate in monkeys, however we now have not disclosed these information in non-human primates, lung penetration. And naturally, we stay up for having lung penetration information in people from the Section 1 bronchoalveolar Lavage research that you’ve cited.

Ritu Baral: Do you’re feeling that the information could also be, or the entry could also be completely different with sufferers which have cavitary MAC versus, I assume, much less massive cavitary illness? Is {that a} consideration for oral remedy?

Sath Shukla: No, that is actually query. And actually, this is applicable to each oral in addition to inhaled types of remedy. So usually talking, in scientific trials to-date, sufferers with massive cavities, i.e. cavitary illness, with cavitary dimension bigger than two centimeters have been excluded from their scientific trials. As a result of these sufferers would require for much longer remedy length one, and so they can also require surgical remedy apart from the medical remedy. So this can be a problem for each oral in addition to inhaled types of remedy. And these sufferers are excluded once more for these causes. However the information that we now have thus far actually means that the drug penetrates, to the place it must get, i.e. the lungs. And naturally, we count on to have information from the bronchoalveolar lavage within the second half of this 12 months, solely to corroborate what we all know from the hole fiber in vitro information, in addition to the non-human primate information.

Ritu Baral: Nice. Thanks for taking all of the questions. I will hop again within the queue.

Operator: Thanks. Our subsequent query is from Louise Chen with Cantor. Please proceed together with your query.

Louise Chen: Hello. Congratulations on the progress this quarter, and thanks for taking my questions right here.

Has your ideas in the marketplace alternative for SPR720 modified in any respect? And if it is permitted, the place do you count on it, to slot in the remedy paradigm, because the area will get a bit bit extra crowded with improvement belongings? After which the second query I had for you, was in the marketplace alternative for SPR206. Do you really plan to maneuver this ahead? And in that case, , what are the subsequent steps right here? Thanks.

Sath Shukla: Thanks for asking, Louise, and nice to listen to from you. I will take the primary half of your first query after which defer to Kamal on the second half of your first query. And I can choose up the 206 query as effectively. For current developments, our info is similar as your info. So, we won’t actually touch upon what really has been the case, , for an additional participant within the area. However for the dimensions of the market, we have not really seen them as opponents per se, as a result of as , we had been in first line, which is a unique market – dimension than refractory, which is the place they had been progressing their belongings. So, what we used to say earlier than, a few of these current information was that we had been very excited concerning the dimension of the market. And what we are saying about these current developments, is that we proceed to be very excited concerning the dimension of the market. What we now have communicated internally, and externally in gentle of those current developments, is that our program is probably the primary oral remedy on the market, actually in first line sufferers, goes to be beneath better analysis and scrutiny, arguably, than ever earlier than. And that is a fantastic problem and a possibility for the group as we progress this ahead. Simply on that SBR720 query, should you would not thoughts rephrasing the second a part of your query and I will move it on to Kamal.

Louise Chen: The, oh, sorry, the 206 query, the one concerning the market…

Sath Shukla: No, you had one other query about 720, proper? On the, the place it suits within the line of remedy, I imagine.

Kamal Hamed: Okay, no, thanks. Thanks, Louise. So, I imply, the current information is actually unlucky for sufferers, as a result of sufferers want newer mixture brokers which have higher tolerability and effectiveness. However having stated that, we’re concentrating on a unique affected person inhabitants, than the affected person inhabitants that is focused, by the opposite ongoing trial, with oral remedy. So, we intention to develop 720, as Sath stated, as a first-line remedy for remedy naive sufferers or remedy expertise sufferers with non-refractive illness. And as we all know, this affected person phase contains nearly all of sufferers, about 75% of the affected person inhabitants. And I ought to be aware that 720 demonstrated, potent exercise towards MAC, low propensity for collection of resistance in an in vitro resistance improvement research. We have additionally proceeded with a Section 2a research, which is the continuing scientific trial presently, with the intention to evaluate the organic impact of SPR720, earlier than we mix it with customary care brokers and later stage, Section 2b/3 program.

Louise Chen: Okay. And something in the marketplace alternative for 206?

Esther Rajavelu: Sure, possibly I will take that, Louise. I believe 206 presents an attention-grabbing alternative for sufferers, as a result of there’s a excessive diploma of unmet want in that affected person inhabitants. Nonetheless, we have at all times commented that we might proceed growing that program contingent on non-dilutive sources of funding.
