Speaker 100:01:34Such forward looking statements are not a guarantee of performance and the company's actual results could differ materially from those contained in such statements. Several factors that could cause or contribute to such differences are described in detail in Spiro Therapeutics' filings with the SEC, including in the Risk Factors section of its annual report on Form 10 ks for the year ended December 31, 2023 filed with the SEC today. These forward looking statements speak only as of the date of this conference call, March 13, 2024, and the company undertakes no obligation to publicly update any forward looking statements or supply new information regarding the company after the date of this call. Participating today's conference call are Saath Shukla, Chief Executive Officer Doctor. Kamal Hamed, Chief Medical Officer and Esther Rajivallo, Chief Financial and Chief Business Officer. Speaker 100:02:30With that, I'd like to turn the call over to Spirit's CEO, Saab Shukla. Saf, please go ahead now. Speaker 200:02:36Thanks, Michael, and I thank you all for joining us this afternoon. Ferro had a very productive 2023 with progress across its portfolio of development stage assets. SPR-seven twenty is now in the later stages of a proof of concept study in NTNPD and we are looking forward to reporting top line data, which we expect to do in the second half of this year. The Phase 3 clinical trial for teripenum HBR is up and running. We recently received IND clearance for SPR206 for the treatment of patients diagnosed with hospital acquired or ventilator associated pneumonia. Speaker 200:03:22The company has a strong balance sheet with the financial to execute on its plans. For me personally, 2023 was a particularly exciting year as I was honored to take on the CEO role and to be provided with the opportunity to lead a world class team who share a vision to develop innovative therapies to help patients suffering from serious infections and rare orphan diseases. Let me begin with SPR-seven twenty, which we are developing for nontuberculous mycobacterial pulmonary disease or NTMPD. We are developing SPR-seven twenty to be a first line oral agent and believe it has exactly the right profile to address the unmet needs in NTNPD. NTNPD is a rare disease, but with a very well identified patient population of approximately 245,000 diagnosed patients in developed markets. Speaker 200:04:26SPR-seven twenty is an oral drug with a novel mechanism of action that is not exploited by other SoC agents or those in development for NTNPD. In the data we have seen so far from completed in vitro and in vivo studies, there has been no evidence of cross resistance against marketed antibiotics and SVR-seven twenty has demonstrated a low propensity for selection of resistance. We have shown that it has potency against multiple NTM pathogens and data support its potential for efficacy, safety and tolerability and macrophage penetration. SPR-seven twenty has also been granted orphan drug, QIDP and Fast Track designations. A goal of our Phase 2a proof of concept clinical trial is to understand SPR-seven twenty's activity in NTNPD patients and to inform the design of a later stage and longer term trial evaluating SPR-seven twenty in combination with current standard of care agents. Speaker 200:05:40As a potential first line oral agent, we believe the commercial opportunity for SPR-seven twenty is compelling. Kamal will provide further details on this program in a few minutes. Turning now to our partner programs. Let me begin with tebipenem HVR, which is partnered with GSK. We are developing tebip as potentially the first oral carbapenem antibiotic for the treatment of complicated urinary tract infections or CUTI. Speaker 200:06:12We were pleased to announce in January of this year that the Phase 3 PIVOT PO clinical trial is now underway with the first patient first visit having occurred in the Q4 of 2023. During 2023, Spero received written agreement from the U. S. FDA with a special protocol assessment or SPA on the design and size of PIVAGE PO. SPA typically represents a very high level of concordance on the overall protocol design between the FDA and a sponsor. Speaker 200:06:49So we believe the regulatory aspect with respect to the design of the program have been de risked substantially. Moving on to SPR206, which is partnered with Pfizer for European markets. We submitted an IND for a Phase 2 clinical trial in HAP BAP patients and recently announced that the IND has been cleared with the FDA. With that, I would now like to hand the call over to Doctor. Kamal Hamid, who will provide more details on the clinical programs. Speaker 300:07:24Thank you, Seth. I will begin with our SPR-seven twenty program, which we hope will deliver the first oral first line treatment for NTMPD. SPR-seven twenty is currently being evaluated in a Phase 2a proof of concept clinical trial. And as Seth mentioned, we are looking forward to sharing top line data, which we expect to do in the second half of this year. NTMPD is a debilitating rare infectious lung disease. Speaker 300:07:57There are currently no approved first line therapies and the current standard of care is a prolonged combination regimen of antibiotics, including azithromycin, ifambutol and rifampin. These have serious tolerability issues and limited effectiveness. The unmet need is for a treatment that has better tolerability and effectiveness, fewer drug drug interactions as well as shorter treatment duration. We believe that SPR-seven twenty will meet these criteria and if approved has the potential to establish a new standard of care in NTMPD. The Phase IIa clinical trial compares SPR-seven twenty monotherapy versus placebo. Speaker 300:08:47It is designed to enroll up to 35 patients who are either treatment naive or treatment experienced, but do not have treatment refractory disease. We currently have 27 active sites that are screening and enrolling patients. The primary endpoint is microbiological response. Specifically, we are measuring the slope change in sputum bacterial burden from baseline through day 56. Success on this endpoint would make SPR-seven twenty the only agent in development we are aware of to demonstrate early bactericidal activity in patients with NTMPD. Speaker 300:09:31We believe that a positive result with supportive evidence from the 12 secondary endpoints will enable us to move confidently into late stage development. We are working on additional development activities needed to support SPR-seven twenty's advancement into late stage clinical studies. These include ongoing toxicology work, CMC initiatives and 2 Phase 1 clinical studies in healthy volunteers currently underway. The first, to assess intra pulmonary pharmacokinetics of SPR-seven nineteen, the active moiety of the prodrug SPR-seven twenty in a broncoalbeolar LAVA study. This should give us a better understanding of the extent of drug penetration into the lungs. Speaker 300:10:20The second is to evaluate the effect on the pharmacokinetics of SPR-seven twenty when co administered with azithromycin and ethambutol. We expect to have results from these studies in the second half of this year as well. Overall, the ongoing studies are expected to provide us with a robust data set that may inform the registrational path for SPR-seven twenty as first line treatment for NTMPD. Now moving on to tabipanum HBR. On January 2, we announced 1st patient first visit in PIVOT PO, the global pivotal Phase 3 clinical trial evaluating tabipenum HBR in hospitalized adult patients with complicated urinary tract infections, including acute pyelonephritis. Speaker 300:11:14Patients are being randomized 1 to 1 to receive sevipenem HBR at a dose of 6 100 milligrams orally every 6 hours or imipenemfilastatin 500 milligrams intravenously every 6 hours for a total of 7 to 10 days. The primary efficacy endpoint is overall response, which is a composite of clinical and microbiological response at the test of cure visit. The primary analysis for the trial will be an assessment of non inferiority in the microbiological intention to treat population based on a 10% non inferiority margin. Target enrollment will be approximately 2,648 patients with randomization stratified by age, baseline diagnosis, I. E. Speaker 300:12:08CUTI or acute pyelonephritis and the presence or absence of urinary tract instrumentation. Enrollment is expected to be completed in the second half of twenty 25. Ferro is responsible for execution of the Phase 3 clinical trial and GSK will be responsible for submitting the NDA. If approved, sevipenem HBR would allow for treatment of CUTI in the outpatient setting. It is well established that patients and physicians generally prefer all treatments. Speaker 300:12:45So we see teripenem as a potentially new and unique paradigm shift from the current IV carbapenem standard of care for how to treat pathogens associated with TUTI. Finally to our SPR206 program. SPR-two zero six is an investigational next generation polymyxin antibiotic we are developing to treat multidrug resistant gram negative infection. SPR206 is designed to disrupt the lipopolysaccharide outer membrane and gram negative bacteria, while reducing the nephrotoxicity potential of polymyxin. Based on microbiological and in vivo testing, we believe that SPR206 has the potential to offer a broad spectrum of activity, including against multidrug resistant and extensively drug resistant strains. Speaker 300:13:42It also has potential for an improved safety profile of reduced nephrotoxicity compared to currently available polymyxin. As Seth mentioned, we announced FDA clearance of the IND on February 28. With that, I'll turn the call over to Esther to review our quarterly financial results. Speaker 400:14:07Thank you, Kamal, and good afternoon or evening to all of you joining us on the call today. Ferro is well capitalized with 76 $300,000 in cash and cash equivalents as of December 31, 2023. As Sath mentioned, in December, upon dosing of the first patient in the Phase 3 PIVOT PO clinical trial, FARO qualified for $95,000,000 in development milestone from GSK. It is payable in 4 equal installments during 24 2025 beginning with the first tranche of $23,800,000 that we received in the Q1 of 2024. We estimate that our cash and cash equivalents together with other non dilutive funding commitments will be sufficient to fund our operating expenses and capital expenditure requirements into late 2025. Speaker 400:15:09Now moving on to summarize our GAAP financials. Total revenue for the Q4 of 2023 was $73,500,000 compared with total revenue of $47,400,000 for the Q4 of 2022. Total revenue for the year ended December 31, 2023 was $103,800,000 compared to $53,500,000 for the year ended December 31, 2022. The revenue increase for the year ended December 31, 2023 was primarily due to $96,700,000 collaboration revenue recognized related to our agreements with GSK and Pfizer during 2023. Research and development expenses for the Q4 of 2023 were $16,600,000 compared to $15,100,000 of R and D expenses for the same period in 2022. Speaker 400:16:11Research and development expenses for the year ended December 31, 2023, were $51,400,000 compared to 47 point $6,000,000 for the year ended December 31, 2022. The increases in research and development expenses were primarily due to increased clinical activity during the period related to our ongoing Phase IIa clinical trial of SPR-seven twenty. G and A expenses for the Q4 of 2023 were $6,400,000 compared to $6,500,000 of G and A expenses for the same period in 2022. This year over year decrease was primarily due to changes in personnel related costs, offset partially by increased professional and consulting fees during the period. G and A expenses for the year ended December 31, 2023 were $25,600,000 compared to 36 point $5,000,000 for the year ended December 31, 2022, primarily as a result of decreases in both personnel costs and professional and consulting fees. Speaker 400:17:22Ferro reported net income of $51,200,000 for the Q4 of 2023 and a full year net income of $22,800,000 for the year ended December 31, 2023, or diluted earnings per share of $0.96 $0.43 respectively. This compares with the net income in the Q4 of 2022 of $26,800,000 or $0.55 of diluted earnings per share of common stock and a net loss for the full year ended December 31, 2022, of $46,400,000 or $1.23 loss per share of common stock. For further details on our financials, please refer to our 10 ks filed with the SEC today. With that, we will now open the call for questions. Operator? Operator00:18:19Thank you. We will now be conducting a question and answer Thank you. Our first question is from Ritu Baral with TD Cowen. Please proceed with your question. Speaker 500:18:58Hi, guys. Thanks for taking the question. Just a couple from me, but one of them, of course, is a little complicated and may have a few parts. One simple one, how is enrollment in 720 going, especially with the halt of enrollment in a competitive program? And my second question also has to do with 720. Speaker 500:19:19Specifically, I'm interested to know more about the 7 19 LOVAGE study in healthy volunteers. Talking to KOLs, one of the concerns around oral NTM compound is Speaker 400:19:37access Speaker 500:19:37to the site of NTM infection, especially when a patient has cavitary disease. How do you guys think of perfusion and access through the biofilm and sort of just location and activity at the site of infection? Thanks. Speaker 200:19:55Ritu, thanks for the question. For your first item on enrollment, we have said in the past that sites have been open, all 27 of them and they continue to dose patients and they are continuing to work towards our guidance of top line data in the second half of this year. For your second question, I'll pass it on to Kamal. Speaker 300:20:19Yes. Hello, Ritu, and thank you for the question. In terms of access of the drug to the site of infection, of course, these patients also have pulmonary hygiene as part of the management of this disease. And this also applies to inhaled therapy because inhaled therapy may have problem with distributing to the site of infection. However, we have demonstrated in the hollow fiber infection model as well as in non human primate in monkeys, but we have not disclosed these data in nonhuman primates, lung penetration. Speaker 300:20:59And of course, we look forward to having lung penetration data in humans from the Phase 1 broncoalveolar LAVAS study that you have cited. Speaker 400:21:11Do you feel that the Speaker 500:21:12data maybe or the access maybe different with patients that have cavitary MAC versus, I guess, less large cavitary disease? Is that a consideration for oral therapy Speaker 200:21:26in No, Speaker 300:21:27that's certainly a good question. And honestly, this applies to both oral as well as inhaled forms of therapy. So typically speaking in clinical trials to date, patients with large cavities, I. E. Cavitory disease with cavity size larger than 2 centimeters have been excluded from the clinical trials because these patients would require much longer treatment duration 1 and they may also require surgical treatment besides the medical treatment. Speaker 300:21:57So this is a challenge for both oral as well as inhaled forms of therapy, and these patients are excluded again for these reasons. But the data that we have so far certainly suggests that the drug penetrates to where it needs to get, I. E, the lungs. And of course, we expect to have data from the broncholvial lavage in the second half of this year only to corroborate what we know from the hollow fiber in vitro data as well as the non human primate data. Speaker 500:22:33Great. Thanks for taking all the questions. I'll hop back in the queue. Operator00:22:40Thank you. Our next question is from Louise Chen with Cantor. Please proceed with your question. Speaker 600:22:45Hi, congratulations on the progress this quarter and thank you for taking my questions here. So first question I had for you was given some of the recent developments in the space, I think one of your competitors reported some data. Has your thoughts on the market opportunity for SPR-seven twenty changed at all? And if it's approved, where do you expect it to fit into the treatment paradigm as the space gets a little bit more crowded with development assets? And then second question I had for you was on the market opportunity for FPR206. Speaker 600:23:15Do you actually plan to move this forward? And if so, what are the next steps here? Thank you. Speaker 200:23:22Thanks for asking, Louis, and great to hear from you. I'll take the first half of your first question and then defer to Kamal on the second half of your first question and I can pick up the 206 question as well. For recent developments, our information is the same as your information. So we can't really comment on what actually has been the case for another player in the space. But for the size of the market, we haven't actually seen them as competitors per se, because as you know, we were in first line, which has a different market size than refractory, which is where they were progressing their assets. Speaker 200:24:08So what we used to say before some of these recent data was that we were very excited about the size of the market. And what we say about these recent developments is that we continue to be very excited about the size of the market. What we have communicated internally and externally in light of these recent developments is that our program is potentially the first oral therapy out there, certainly in first line patients, is going to be under greater evaluation and scrutiny arguably than ever before. And that's a great challenge and an opportunity for the organization as we progress this forward. Just on that SPR-seven twenty question, if you wouldn't mind rephrasing the second part of your question and I'll pass it on to Kamal. Speaker 600:25:02The sorry, the 206 question, the one about the market. Speaker 200:25:05No, you had another question about 722, right? On the where it fits in the line of treatment, I believe? Speaker 600:25:14Yes, that is correct. Yes, if you were to get it approved. Speaker 300:25:18Okay. No, thank you. Thank you, Louise. So I mean the recent news is certainly unfortunate for patients because patients need newer combination agents that have better tolerability and effectiveness. But having said that, we are targeting a different patient population than the patient population that's targeted by the other ongoing trial with oral therapy. Speaker 300:25:47So we aim to develop 720, as Seth said, as a first line therapy for treatment naive patients our treatment experienced patients with non refractory disease. And as we know, this patient segment comprises the majority of patients, about 75% of the patient population. And I should note that 720 demonstrated potent activity against MAC, low propensity for selection of resistance in an in vitro resistance development study, we've also proceeded with a Phase 2a study, which is the ongoing clinical trial at this time with the aim to assess the biological effect of SPR-seven twenty before we combine it with standard of care agents in later stage Phase IIbIII program. Speaker 600:26:44Okay. And anything on the market opportunity for 206? Speaker 400:26:49Yes. Maybe I'll take that, Louise. I think 206 presents an interesting opportunity for patients because there is a high degree of unmet need in that patient population. However, we've always commented that we would continue developing that program contingent on non dilutive sources of funding. As you know, we have a partnership with Pfizer for European markets and with Everest for China, and we also collaborate with government agencies to obtain funding. Speaker 400:27:20So we're looking at any and all of those sources for continued funding for that program. Thank you. Operator00:27:33Thank you. There are no further questions at this time. I would like to hand the call back to Mr. Shukla for any closing comments. Speaker 200:27:45Well, I'd just like to thank everyone for dialing in today and have a wonderful day.Read morePowered by Conference Call Audio Live Call not available Earnings Conference CallSpero Therapeutics Q4 202300:00 / 00:00Speed:1x1.25x1.5x2x Earnings DocumentsPress Release(8-K)Annual report(10-K) Spero Therapeutics Earnings HeadlinesSpero Therapeutics Analyst RatingsApril 7, 2025 | benzinga.comTD Cowen Sticks to Their Hold Rating for Spero Therapeutics (SPRO)April 2, 2025 | markets.businessinsider.comTrump and Musk fight backIs there more to the Musk–Trump relationship than meets the eye?

Ferro had a very productive 2023 with progress across its portfolio of development stage assets. SPR-seven twenty is now in the later stages of a proof of concept study in NTNPD and we are looking forward to reporting top line data, which we expect to do in the second half of this year. The Phase 3 clinical trial for teripenum HBR is up and running. We recently received IND clearance for SPR206 for the treatment of patients diagnosed with hospital acquired or ventilator associated pneumonia. Speaker 200:03:22The company has a strong balance sheet with the financial to execute on its plans. For me personally, 2023 was a particularly exciting year as I was honored to take on the CEO role and to be provided with the opportunity to lead a world class team who share a vision to develop innovative therapies to help patients suffering from serious infections and rare orphan diseases. Let me begin with SPR-seven twenty, which we are developing for nontuberculous mycobacterial pulmonary disease or NTMPD. We are developing SPR-seven twenty to be a first line oral agent and believe it has exactly the right profile to address the unmet needs in NTNPD. NTNPD is a rare disease, but with a very well identified patient population of approximately 245,000 diagnosed patients in developed markets. Speaker 200:04:26SPR-seven twenty is an oral drug with a novel mechanism of action that is not exploited by other SoC agents or those in development for NTNPD. In the data we have seen so far from completed in vitro and in vivo studies, there has been no evidence of cross resistance against marketed antibiotics and SVR-seven twenty has demonstrated a low propensity for selection of resistance. We have shown that it has potency against multiple NTM pathogens and data support its potential for efficacy, safety and tolerability and macrophage penetration. SPR-seven twenty has also been granted orphan drug, QIDP and Fast Track designations. A goal of our Phase 2a proof of concept clinical trial is to understand SPR-seven twenty's activity in NTNPD patients and to inform the design of a later stage and longer term trial evaluating SPR-seven twenty in combination with current standard of care agents. Speaker 200:05:40As a potential first line oral agent, we believe the commercial opportunity for SPR-seven twenty is compelling. Kamal will provide further details on this program in a few minutes. Turning now to our partner programs. Let me begin with tebipenem HVR, which is partnered with GSK. We are developing tebip as potentially the first oral carbapenem antibiotic for the treatment of complicated urinary tract infections or CUTI. Speaker 200:06:12We were pleased to announce in January of this year that the Phase 3 PIVOT PO clinical trial is now underway with the first patient first visit having occurred in the Q4 of 2023. During 2023, Spero received written agreement from the U. S. FDA with a special protocol assessment or SPA on the design and size of PIVAGE PO. SPA typically represents a very high level of concordance on the overall protocol design between the FDA and a sponsor. Speaker 200:06:49So we believe the regulatory aspect with respect to the design of the program have been de risked substantially. Moving on to SPR206, which is partnered with Pfizer for European markets. We submitted an IND for a Phase 2 clinical trial in HAP BAP patients and recently announced that the IND has been cleared with the FDA. With that, I would now like to hand the call over to Doctor. Kamal Hamid, who will provide more details on the clinical programs. Speaker 300:07:24Thank you, Seth. I will begin with our SPR-seven twenty program, which we hope will deliver the first oral first line treatment for NTMPD. SPR-seven twenty is currently being evaluated in a Phase 2a proof of concept clinical trial. And as Seth mentioned, we are looking forward to sharing top line data, which we expect to do in the second half of this year. NTMPD is a debilitating rare infectious lung disease. Speaker 300:07:57There are currently no approved first line therapies and the current standard of care is a prolonged combination regimen of antibiotics, including azithromycin, ifambutol and rifampin. These have serious tolerability issues and limited effectiveness. The unmet need is for a treatment that has better tolerability and effectiveness, fewer drug drug interactions as well as shorter treatment duration. We believe that SPR-seven twenty will meet these criteria and if approved has the potential to establish a new standard of care in NTMPD. The Phase IIa clinical trial compares SPR-seven twenty monotherapy versus placebo. Speaker 300:08:47It is designed to enroll up to 35 patients who are either treatment naive or treatment experienced, but do not have treatment refractory disease. We currently have 27 active sites that are screening and enrolling patients. The primary endpoint is microbiological response. Specifically, we are measuring the slope change in sputum bacterial burden from baseline through day 56. Success on this endpoint would make SPR-seven twenty the only agent in development we are aware of to demonstrate early bactericidal activity in patients with NTMPD. Speaker 300:09:31We believe that a positive result with supportive evidence from the 12 secondary endpoints will enable us to move confidently into late stage development. We are working on additional development activities needed to support SPR-seven twenty's advancement into late stage clinical studies. These include ongoing toxicology work, CMC initiatives and 2 Phase 1 clinical studies in healthy volunteers currently underway. The first, to assess intra pulmonary pharmacokinetics of SPR-seven nineteen, the active moiety of the prodrug SPR-seven twenty in a broncoalbeolar LAVA study. This should give us a better understanding of the extent of drug penetration into the lungs. Speaker 300:10:20The second is to evaluate the effect on the pharmacokinetics of SPR-seven twenty when co administered with azithromycin and ethambutol. We expect to have results from these studies in the second half of this year as well. Overall, the ongoing studies are expected to provide us with a robust data set that may inform the registrational path for SPR-seven twenty as first line treatment for NTMPD. Now moving on to tabipanum HBR. On January 2, we announced 1st patient first visit in PIVOT PO, the global pivotal Phase 3 clinical trial evaluating tabipenum HBR in hospitalized adult patients with complicated urinary tract infections, including acute pyelonephritis. Speaker 300:11:14Patients are being randomized 1 to 1 to receive sevipenem HBR at a dose of 6 100 milligrams orally every 6 hours or imipenemfilastatin 500 milligrams intravenously every 6 hours for a total of 7 to 10 days. The primary efficacy endpoint is overall response, which is a composite of clinical and microbiological response at the test of cure visit. The primary analysis for the trial will be an assessment of non inferiority in the microbiological intention to treat population based on a 10% non inferiority margin. Target enrollment will be approximately 2,648 patients with randomization stratified by age, baseline diagnosis, I. E. Speaker 300:12:08CUTI or acute pyelonephritis and the presence or absence of urinary tract instrumentation. Enrollment is expected to be completed in the second half of twenty 25. Ferro is responsible for execution of the Phase 3 clinical trial and GSK will be responsible for submitting the NDA. If approved, sevipenem HBR would allow for treatment of CUTI in the outpatient setting. It is well established that patients and physicians generally prefer all treatments. Speaker 300:12:45So we see teripenem as a potentially new and unique paradigm shift from the current IV carbapenem standard of care for how to treat pathogens associated with TUTI. Finally to our SPR206 program. SPR-two zero six is an investigational next generation polymyxin antibiotic we are developing to treat multidrug resistant gram negative infection. SPR206 is designed to disrupt the lipopolysaccharide outer membrane and gram negative bacteria, while reducing the nephrotoxicity potential of polymyxin. Based on microbiological and in vivo testing, we believe that SPR206 has the potential to offer a broad spectrum of activity, including against multidrug resistant and extensively drug resistant strains. Speaker 300:13:42It also has potential for an improved safety profile of reduced nephrotoxicity compared to currently available polymyxin. As Seth mentioned, we announced FDA clearance of the IND on February 28. With that, I'll turn the call over to Esther to review our quarterly financial results. Speaker 400:14:07Thank you, Kamal, and good afternoon or evening to all of you joining us on the call today. Ferro is well capitalized with 76 $300,000 in cash and cash equivalents as of December 31, 2023. As Sath mentioned, in December, upon dosing of the first patient in the Phase 3 PIVOT PO clinical trial, FARO qualified for $95,000,000 in development milestone from GSK. It is payable in 4 equal installments during 24 2025 beginning with the first tranche of $23,800,000 that we received in the Q1 of 2024. We estimate that our cash and cash equivalents together with other non dilutive funding commitments will be sufficient to fund our operating expenses and capital expenditure requirements into late 2025. Speaker 400:15:09Now moving on to summarize our GAAP financials. Total revenue for the Q4 of 2023 was $73,500,000 compared with total revenue of $47,400,000 for the Q4 of 2022. Total revenue for the year ended December 31, 2023 was $103,800,000 compared to $53,500,000 for the year ended December 31, 2022. The revenue increase for the year ended December 31, 2023 was primarily due to $96,700,000 collaboration revenue recognized related to our agreements with GSK and Pfizer during 2023. Research and development expenses for the Q4 of 2023 were $16,600,000 compared to $15,100,000 of R and D expenses for the same period in 2022. Speaker 400:16:11Research and development expenses for the year ended December 31, 2023, were $51,400,000 compared to 47 point $6,000,000 for the year ended December 31, 2022. The increases in research and development expenses were primarily due to increased clinical activity during the period related to our ongoing Phase IIa clinical trial of SPR-seven twenty. G and A expenses for the Q4 of 2023 were $6,400,000 compared to $6,500,000 of G and A expenses for the same period in 2022. This year over year decrease was primarily due to changes in personnel related costs, offset partially by increased professional and consulting fees during the period. G and A expenses for the year ended December 31, 2023 were $25,600,000 compared to 36 point $5,000,000 for the year ended December 31, 2022, primarily as a result of decreases in both personnel costs and professional and consulting fees. Speaker 400:17:22Ferro reported net income of $51,200,000 for the Q4 of 2023 and a full year net income of $22,800,000 for the year ended December 31, 2023, or diluted earnings per share of $0.96 $0.43 respectively. This compares with the net income in the Q4 of 2022 of $26,800,000 or $0.55 of diluted earnings per share of common stock and a net loss for the full year ended December 31, 2022, of $46,400,000 or $1.23 loss per share of common stock. For further details on our financials, please refer to our 10 ks filed with the SEC today. With that, we will now open the call for questions. Operator? Operator00:18:19Thank you. We will now be conducting a question and answer Thank you. Our first question is from Ritu Baral with TD Cowen. Please proceed with your question. Speaker 500:18:58Hi, guys. Thanks for taking the question. Just a couple from me, but one of them, of course, is a little complicated and may have a few parts. One simple one, how is enrollment in 720 going, especially with the halt of enrollment in a competitive program? And my second question also has to do with 720. Speaker 500:19:19Specifically, I'm interested to know more about the 7 19 LOVAGE study in healthy volunteers. Talking to KOLs, one of the concerns around oral NTM compound is Speaker 400:19:37access Speaker 500:19:37to the site of NTM infection, especially when a patient has cavitary disease. How do you guys think of perfusion and access through the biofilm and sort of just location and activity at the site of infection? Thanks. Speaker 200:19:55Ritu, thanks for the question. For your first item on enrollment, we have said in the past that sites have been open, all 27 of them and they continue to dose patients and they are continuing to work towards our guidance of top line data in the second half of this year. For your second question, I'll pass it on to Kamal. Speaker 300:20:19Yes. Hello, Ritu, and thank you for the question. In terms of access of the drug to the site of infection, of course, these patients also have pulmonary hygiene as part of the management of this disease. And this also applies to inhaled therapy because inhaled therapy may have problem with distributing to the site of infection. However, we have demonstrated in the hollow fiber infection model as well as in non human primate in monkeys, but we have not disclosed these data in nonhuman primates, lung penetration. Speaker 300:20:59And of course, we look forward to having lung penetration data in humans from the Phase 1 broncoalveolar LAVAS study that you have cited. Speaker 400:21:11Do you feel that the Speaker 500:21:12data maybe or the access maybe different with patients that have cavitary MAC versus, I guess, less large cavitary disease? Is that a consideration for oral therapy Speaker 200:21:26in No, Speaker 300:21:27that's certainly a good question. And honestly, this applies to both oral as well as inhaled forms of therapy. So typically speaking in clinical trials to date, patients with large cavities, I. E. Cavitory disease with cavity size larger than 2 centimeters have been excluded from the clinical trials because these patients would require much longer treatment duration 1 and they may also require surgical treatment besides the medical treatment. Speaker 300:21:57So this is a challenge for both oral as well as inhaled forms of therapy, and these patients are excluded again for these reasons. But the data that we have so far certainly suggests that the drug penetrates to where it needs to get, I. E, the lungs. And of course, we expect to have data from the broncholvial lavage in the second half of this year only to corroborate what we know from the hollow fiber in vitro data as well as the non human primate data. Speaker 500:22:33Great. Thanks for taking all the questions. I'll hop back in the queue. Operator00:22:40Thank you. Our next question is from Louise Chen with Cantor. Please proceed with your question. Speaker 600:22:45Hi, congratulations on the progress this quarter and thank you for taking my questions here. So first question I had for you was given some of the recent developments in the space, I think one of your competitors reported some data. Has your thoughts on the market opportunity for SPR-seven twenty changed at all? And if it's approved, where do you expect it to fit into the treatment paradigm as the space gets a little bit more crowded with development assets? And then second question I had for you was on the market opportunity for FPR206. Speaker 600:23:15Do you actually plan to move this forward? And if so, what are the next steps here? Thank you. Speaker 200:23:22Thanks for asking, Louis, and great to hear from you. I'll take the first half of your first question and then defer to Kamal on the second half of your first question and I can pick up the 206 question as well. For recent developments, our information is the same as your information. So we can't really comment on what actually has been the case for another player in the space. But for the size of the market, we haven't actually seen them as competitors per se, because as you know, we were in first line, which has a different market size than refractory, which is where they were progressing their assets. Speaker 200:24:08So what we used to say before some of these recent data was that we were very excited about the size of the market. And what we say about these recent developments is that we continue to be very excited about the size of the market. What we have communicated internally and externally in light of these recent developments is that our program is potentially the first oral therapy out there, certainly in first line patients, is going to be under greater evaluation and scrutiny arguably than ever before. And that's a great challenge and an opportunity for the organization as we progress this forward. Just on that SPR-seven twenty question, if you wouldn't mind rephrasing the second part of your question and I'll pass it on to Kamal. Speaker 600:25:02The sorry, the 206 question, the one about the market. Speaker 200:25:05No, you had another question about 722, right? On the where it fits in the line of treatment, I believe? Speaker 600:25:14Yes, that is correct. Yes, if you were to get it approved. Speaker 300:25:18Okay. No, thank you. Thank you, Louise. So I mean the recent news is certainly unfortunate for patients because patients need newer combination agents that have better tolerability and effectiveness. But having said that, we are targeting a different patient population than the patient population that's targeted by the other ongoing trial with oral therapy. Speaker 300:25:47So we aim to develop 720, as Seth said, as a first line therapy for treatment naive patients our treatment experienced patients with non refractory disease. And as we know, this patient segment comprises the majority of patients, about 75% of the patient population. And I should note that 720 demonstrated potent activity against MAC, low propensity for selection of resistance in an in vitro resistance development study, we've also proceeded with a Phase 2a study, which is the ongoing clinical trial at this time with the aim to assess the biological effect of SPR-seven twenty before we combine it with standard of care agents in later stage Phase IIbIII program. Speaker 600:26:44Okay. And anything on the market opportunity for 206? Speaker 400:26:49Yes. Maybe I'll take that, Louise. I think 206 presents an interesting opportunity for patients because there is a high degree of unmet need in that patient population. However, we've always commented that we would continue developing that program contingent on non dilutive sources of funding. As you know, we have a partnership with Pfizer for European markets and with Everest for China, and we also collaborate with government agencies to obtain funding. Speaker 400:27:20So we're looking at any and all of those sources for continued funding for that program. Thank you. Operator00:27:33Thank you. There are no further questions at this time. I would like to hand the call back to Mr. Shukla for any closing comments. Speaker 200:27:45Well, I'd just like to thank everyone for dialing in today and have a wonderful day.Read morePowered by
