A Prospective, Single-arm, Multicenter, Observational Safety Surveillance Study of VyndaMx® (Tafamidis Capsule 61 mg) in Patients With Transthyretin Amyloid Cardiomyopathy (ATTR-CM) in India

The purpose of this study is to learn about the safety of Tafamidis for the treatment of Transthyretin amyloid cardiomyopathy (ATTR-CM) in India.
ATTR-CM is a condition that affects people's hearts. Transthyretin is a protein that is made in the liver. In some people this protein stops working and forms clumps called as amyloid. Transthyretin amyloid builds up in heart and stops the heart from pumping properly.
This study is seeking for participants who are:
* confirmed with ATTR-CM.
* given Tafamidis capsules to be taken by mouth.
The safety of Tafamidis capsules will be checked based on side effects. These side effects can happen within 6 months after taking Tafamidis. A side effect is something (expected or unexpected) that you feel was caused by a medicine or treatment you take. The study doctor will collect side effect information and put the information on patient's case form.
Follow-up of the patient's will be performed via clinic re-visit or over a call. It is not a rule for the participants to visit the clinic in this study.
This study will help to see if Tafamidis is safe.

Etiological Treatment of Cardiac Amyloidosis: Standard of Care and Future Directions

Review

Author: Morfino, Paolo ; Emdin, Michele ; Vergaro, Giuseppe ; Chubuchna, Olena ; Aimo, Alberto ; Castiglione, Vincenzo ; Buda, Gabriele ; Ferrari Chen, Yu Fu ; Fabiani, Iacopo

Abstract:

Purpose of Review:

Cardiac amyloidosis (CA) is a condition caused by interstitial infiltration of misfolded proteins structured into amyloid fibrils. Transthyretin (ATTR) and immunoglobulin light chain (AL) amyloidosis represent the most common forms of CA. CA was traditionally perceived as a rare and incurable disease, but diagnostic and therapeutic advances have undermined the conventional paradigm.

Recent Findings:

The standard of care for ATTR-CA include agents capable of selectively stabilizing the precursor protein (e.g., tafamidis), whereas the plasma cell clone is the main target of chemotherapy for AL-CA. For long, tafamidis represented the only drug approved for patients with ATTR-CA. Recent data from ATTRibute-CM led to the approval of acoramidis, whereas patisiran received refusal based on the APOLLO-B trial. Novel CRISPR-Cas9-based drugs (i.e., NTLA-2001) hold great potential in the setting of ATTR-CA. Several hematological regimens are available to treat AL-CA. The main limit of current therapies is their inability to trigger removal of amyloid from tissues. However, the investigation of monoclonal antibodies targeting misfolded ATTR (e.g., PRX004, NI301A) or AL (e.g., birtamimab, anselamimab) has led to encouraging results.

Summary:

Various cutting-edge strategies are being tested for treatment of CA and may change the prognostic landscape of this condition in the next years.

Transthyretin as a therapeutic target: the future of disease-modifying therapies for Alzheimer’s disease

Review

Author: Shaw, Swetaleena ; Aran, Khadga Raj ; Porel, Pratyush

BACKGROUND:

Alzheimer's disease (AD) is the most common neurodegenerative disease for causing memory deficits and primarily characterized by extracellular deposition of amyloid-β (Aβ) plaques, intracellular neurofibrillary tangles (NFTs), and hyperphosphorylation of tau protein, all are pathological hallmarks for AD. Transthyretin (TTR) is a highly conserved homo-tetrameric protein, primarily synthesized in liver and choroid plexus, and most importantly involved in transport of T₃-T₄ hormones and retinol.

OBJECTIVES:

This review explores the dual role of TTR, with a greater emphasis on its neuroprotective action, particularly in AD.

METHODS:

Based on the available literature, TTR's potential as a biomarker in the central nervous system (CNS), focusing its role in stabilizing Aβ aggregation and the senile plaque formation during neurodegeneration. Additionally, TTR's dual roles, in neurodegeneration and neuroprotection are studied, emphasizing its potential for improving AD diagnosis and treatment strategies.

RESULTS:

Recent research has revealed that TTR is gradually showcasing its promise in neuroprotection and neuronal viability in AD by binding with Aβ and mitigating its neurotoxic effects. Current preclinical and clinical studies also support that TTR is actively involved in maintaining the blood-brain barrier (BBB) integrity and maintain neurotransmitter balance, all of which offer significant therapeutic promise through TTR stabilizers, such as Tafamidis, Acoramidis, and Vutrisiran, highlighting their potential in AD treatment CONCLUSION: This review concludes that TTR plays bidirectional role and gaining interest as a potential biomarker, though several challenges must be addressed before it can be established a novel therapeutic target in AD management in the modern era of drug discovery.

Abstract:

Aims:

Patients with cardiomyopathies are a heterogeneous group of patients who experience high morbidity and mortality. Early cardiac assessment and intervention with access to genetic counselling in a multidisciplinary Cardiomyopathy Clinic may improve outcomes and prevent progression to advanced heart failure.

Methods and results:

Our prospective cohort study was conducted at a multidisciplinary Cardiomyopathy Clinic with 421 patients enrolled (42.5% female, median age 58 years), including 224 patients with dilated cardiomyopathy (DCM, 42.9% female, median age 57 years), 72 with hypertrophic cardiomyopathy (HCM, 43.1% female, median age 60 years), 79 with infiltrative cardiomyopathy (65.8% female, median age 70 years) and 46 who were stage A/at risk for genetic cardiomyopathy (54.3% female, median age 36 years). Patients were seen in follow‐up at a median of 18 months. A pathogenic/likely pathogenic variant was identified in 28.5% of the total cohort, including 33.3% of the DCM cohort (28% TTN mutations) and 34.1% of the HCM cohort (60% MYBPC3 and 20% MYH7) who underwent genetic testing. The use of angiotensin‐converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor neprilysin inhibitor (48.3–69.5% of total cohort, P < 0.001), β‐blockers (58.4–72.4%, P < 0.001), mineralocorticoid receptor antagonists (33.9–41.4%, P = 0.0014) and sodium/glucose cotransporter‐2 inhibitors (5.3–27.9%, P < 0.001) all increased at follow‐up. Precision‐based therapies were also implemented, including tafamidis for transthyretin amyloidosis (n = 21), enzyme replacement therapy for Fabry disease (n = 14) and mavacamten (n = 4) for HCM. Optimization of medications and devices resulted in improvements in left ventricular ejection fraction (LVEF) from 27% to 43% at follow‐up for DCM patients with reduced LVEF at baseline (P < 0.001) and reduction in left ventricular mass index (LVMI) from 156 g/m2 to 128 g/m2 at follow‐up for HCM patients with abnormal LVMI at baseline (P = 0.009). Optimization of therapies was associated with stable plasma biomarkers in stage B patients while lowering levels of BNP (619–517.5 pg/mL, P = 0.048), NT‐proBNP (777.5–356 ng/L, P < 0.001) and hsTropT (31–22 ng/L, P = 0.005) at follow‐up relative to baseline values for stage C patients. Despite stage B patients having overt cardiomyopathy at baseline, stage A and B patients had a similarly high probability of survival (χ2 = 0.204, P = 0.652). The overall cardiovascular mortality rate was low at 1.7% for the cohort (0.5% for stage B and 3.3% for stage C) over a median of 34‐month follow‐up.

Conclusion:

Our study demonstrates that a multidisciplinary cardiomyopathy clinic can improve the clinical profiles of patients with diverse genetic cardiomyopathies.

Acoramidis Reduced Incidence of Atrial Fibrillation Events in Patients with ATTR-CM

- In a post-hoc analysis of ATTRibute-CM, acoramidis reduced the annual frequency of CVH due to AF/AFL by 43% compared to placebo and reduced the incidence of new-onset AF/AFL by 17% in the subgroup with no prior history of AF compared to placebo - In the ATTRibute-CM study, acoramidis demonstrated the most rapid benefit seen in any Phase 3 study of ATTR-CM to date in both ATTRv-CM and ATTRwt-CM patients: - In as few as 3 months, the time to first event (ACM or CVH) durably separated relative to placebo- A 42% reduction in composite ACM and recurrent CVH events relative to placebo at Month 30- A 50% reduction in the cumulative frequency of CVH events relative to placebo at Month 30 - Acoramidis is approved as Attruby™ by the U.S. FDA and is approved as BEYONTTRA® by the European Commission, Japanese Pharmaceuticals and Medical Devices Agency and UK Medicines and Healthcare Products Regulatory Agency PALO ALTO, Calif., May 20, 2025 (GLOBE NEWSWIRE) -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) (“BridgeBio” or the “Company”), a new type of biopharmaceutical company focused on genetic diseases, presented data from ATTRibute-CM, highlighting the reduced incidence of atrial fibrillation (AF) events in the overall ATTR-CM population. These data were presented in a moderated ePoster at the Annual Congress of the Heart Failure Association of the ESC (Heart Failure 2025), taking place in Belgrade, Serbia from May 17 - 20, 2025. Acoramidis is a selective small molecule, orally administered, near-complete (≥90%) transthyretin (TTR) stabilizer. “The reduction in new-onset atrial fibrillation and AF-related hospitalizations represents an important finding for the ATTR-CM community. I am encouraged by the growing body of data from the ATTRibute-CM study, which adds to the understanding of acoramidis and its potential impact on clinical outcomes for patients. Furthermore, the observed reductions in hospitalizations and mortality, along with improvements in functional capacity and quality of life, suggest that acoramidis may offer benefit to both variant and wild-type ATTR-CM patients who have limited treatment options,” said Kevin Alexander, M.D. of Stanford University School of Medicine, USA. “These data support further consideration of acoramidis as a promising front-line therapy for ATTR-CM, particularly for patients with the hereditary form of the disease, who often face rapid and severe progression.” Details from the post-hoc analysis on incidence of AF in ATTRibute-CM included: Acoramidis Treatment Is Associated with a Lower Incidence of Atrial Fibrillation-related Events in Patients with ATTR-CM: A Post-hoc Analysis of the ATTRibute-CM Trial, presented by Dr. Alexander AF is a common complication of ATTR-CM, observed in up to 70% of patients, and the onset of AF is associated with an increased risk of cardiovascular-related hospitalizations (CVH)In ATTRibute-CM, a 43% relative risk reduction in the annual frequency of CVH due to AF/atrial flutter (AFL) was observed with acoramidis relative to placebo. In the subgroup who had no prior history of AF, a 17% lower incidence of new-onset AF/AFL was reported with acoramidis compared to placeboThese findings show the potential of acoramidis to reduce both disease progression, as indicated by a lower incidence of new-onset AF/AFL, and CVH morbidity caused by AF/AFL, in patients with ATTR-CM In addition to the moderated ePoster, three analyses were shared on the strong clinical outcomes in ATTRv-CM versus placebo. ATTRv-CM is associated with early age of disease onset with more advanced heart failure symptoms, which often leads to a poorer prognosis than those with wild-type ATTR-CM (ATTRwt-CM). These findings included: Acoramidis Improves Serum TTR Levels in Patients with Wild-type or Variant Transthyretin Amyloid Cardiomyopathy: Results from ATTRibute-CM, presented by Anique Ducharme, M.D. of Université de Montréal, CAN In both subgroups of ATTRv-CM and ATTRwt-CM, acoramidis treatment induced a rapid increase in serum TTR levels, a measure of TTR stability, by Day 28, with comparable serum TTR levels achieved in both subgroups from Day 28 through Month 30. Relative increases in serum TTR concentrations resulting from greater TTR stability have been associated with reduced risk of all-cause and cardiovascular mortality in the general population in recent literature1 Effect of Acoramidis on Functional Capacity and Quality of Life in Patients with Variant ATTR-CM: Results from ATTRibute-CM, presented by Marianna Fontana, M.D. of University College London, UK Data from ATTRibute-CM showed that when acoramidis was administered for 30 months, participants with ATTRv-CM had a clinically significant slower decline in functional capacity and quality of life compared with placebo, consistent with the overall results in both ATTRv-CM and ATTRwt-CMAt Month 30, the mean difference between acoramidis and placebo treatment groups in the change from baseline in 6-minute walk distance was 86.7 meters (p = 0.0048) in favor of acoramidis and in the change from baseline in KCCQ-OS at Month 30, was 20.3 points (p = 0.0019) in favor of acoramidis, in patients with ATTRv-CM Effect of Acoramidis on All-cause Mortality, Cardiovascular Hospitalization and NT-proBNP in Variant ATTR-CM: Results from ATTRibute-CM, presented by Marianna Fontana, M.D. of University College London, UK In ATTRibute-CM, acoramidis treatment administered for 30 months led to a substantial reduction (>50%) in the composite of all-cause mortality (ACM)/CVH, ACM and CVH in participants with ATTRv-CM compared to placebo. This improvement was accompanied by favorable effects on N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels “Based on the findings from ATTRibute-CM, we believe that acoramidis has the potential to enable patients with both variant and wild-type ATTR-CM to live longer, healthier lives, especially for those with variant ATTR-CM who typically have a poorer prognosis. We observed both a striking reduction in the frequency of cardiovascular hospitalizations (which included clinic or emergency department visits for urgent heart failure management) and a clinically important and statistically significant reduction in all-cause mortality in the important subgroup. These clinical outcomes were further mirrored in robust improvements in functional capacity, quality of life, and biomarkers of heart failure severity,” said Jonathan Fox, M.D., Ph.D., President and Chief Medical Officer of BridgeBio Cardiorenal. “Given these compelling results, acoramidis should be considered as first-line treatment for newly diagnosed patients, and those currently on other therapies could be switched to acoramidis to maximize their potential to achieve such benefits.” Additional acoramidis moderated ePosters at Heart Failure 2025 included: Disease Progression Among Patients Receiving Tafamidis for ATTR-CM in a Real-world Setting, presented by Daniel P. Judge, M.D. of Medical University of South Carolina, USA This analysis suggests disease progression despite treatment with tafamidis in ATTR-CM. CVH was frequent, with approximately 1 in 5 tafamidis-treated patients hospitalized in the first six months of therapy. As more therapeutic options become available, measuring the clinical effectiveness of therapies in a real-world setting will be important to help inform physicians and patients when making treatment decisions Cause of Death in Patients with Transthyretin Amyloid Cardiomyopathy (ATTR-CM): Findings from the ATTRibute-CM Study, presented by Laura Obici, M.D. of University of Pavia, ESP In the ATTRibute-CM study, total deaths were numerically lower with acoramidis compared with placebo. The relative risk reduction of 30% in cardiovascular-related mortality by Month 30 was driven predominantly by a reduction in heart failure-related deaths Time from First Recorded Clinical Manifestation to Diagnosis of Transthyretin Amyloid Cardiomyopathy: A Retrospective Cohort Study Using U.S. Claims Data, presented by Joshua Mitchell, M.D., Washington University School of Medicine in St. Louis, USA The median time from the first documented clinical manifestation to ATTR-CM diagnosis was almost 5 years, and over 2 years from the first heart failure diagnosis. This demonstrates that the patient journey to an ATTR-CM diagnosis can be prolonged and challenging, which potentially leads to more severe disease at diagnosis. Understanding the factors contributing to diagnostic delays is important to improving diagnostic pathways and patient outcomes Acoramidis is approved as Attruby by the U.S. FDA and is approved as BEYONTTRA by the European Commission, Japanese Pharmaceuticals and Medical Devices Agency, and the UK Medicines and Healthcare Products Regulatory Agency with all labels specifying near-complete stabilization of TTR. More data on the benefit of Attruby for ATTR-CM patients is planned for future medical meetings. 1Christoffersen M et al.

AMVUTTRA ® (vutrisiran) Significantly Reduces Mortality and a Range of Important Cardiovascular Events in Patients with ATTR Amyloidosis with Cardiomyopathy: Additional Data from HELIOS-B

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, today presented the most contemporary analysis of the HELIOS-B Phase 3 study of vutrisiran for the treatment of ATTR amyloidosis with cardiomyopathy (ATTR-CM) as a late-breaking abstract at the Heart Failure 2025 Congress, a scientific congress of the European Society of Cardiology, taking place May 17-20 in Belgrade, Serbia. The results demonstrate that vutrisiran, which rapidly knocks down transthyretin, reduces key cardiovascular (CV) events such as CV hospitalizations, and heart failure (HF) hospitalizations. Additionally, in the analysis, urgent HF visits were reduced by 46% (95% CI: 0.30, 0.98; p = 0.041) in the overall population during the double-blind period, compared to placebo. These CV events often precede all-cause mortality (ACM) and are key indicators of disease progression. Importantly, results from the November 2024 data cut, including further follow up through up to 42 months, reinforce the primary HELIOS-B analysis showing vutrisiran’s effect on ACM, and further demonstrate that vutrisiran reduces CV mortality. Through 42 months, the risk of ACM was reduced by 36% (95% CI: 0.46, 0.88; p = 0.007) and the risk of CV mortality was reduced by 33% (95% CI: 0.47, 0.96; p = 0.038) in the overall population, compared to placebo. For both the primary analysis and the current analysis, vital status through 42 months was ascertained for over 99% of all randomized patients from the HELIOS-B study, underscoring the robustness of the results. The study was conducted in a contemporary patient population with patients receiving robust background therapy, inclusive of treatment with a TTR stabilizer and SGLT2 inhibitors. The analysis of the HELIOS-B Phase 3 study, including mortality data through up to 42 months, was simultaneously published in JACC. “From the primary analysis of HELIOS-B, we know that AMVUTTRA profoundly impacts all-cause mortality, while preserving patients’ functional capacity and quality of life,” said Pushkal Garg, M.D., Chief Medical Officer of Alnylam. “These new data—including the impact on mortality, on cardiovascular events and on urgent heart failure visits, the latter of which was reduced by nearly half—add to the story of consistency and magnitude of benefit. I remain impressed by the HELIOS-B results, which are noteworthy given the substantial use of heart failure treatments in the study population, and I believe they continue to reinforce AMVUTTRA as a clinically differentiated, first-line option for patients with ATTR-CM.” The results from the analysis underscore the rapid and sustained benefits of vutrisiran in treating ATTR-CM across key endpoints: Impact of Vutrisiran Versus Placebo Overall Population N=654 Reduction in Urgent HF Visits through 36 Months 46% RR: 0.54 P = 0.041 Reduction in HF Hospitalizations through 36 Months 33% RR: 0.67 P = 0.002 Reduction in Risk of CV Events through 36 Months 27% RR: 0.73 P = 0.001 Reduction in CV Hospitalizations through 36 Months 25% RR: 0.75 P = 0.004 Reduction in Risk of ACM through 42 Months 36% HR: 0.64 P = 0.007 Reduction in CV Mortality through 42 Months 33% HR: 0.67 P = 0.038 In a separate presentation on Tuesday, May 20, Alnylam will share findings from a subgroup analysis of HELIOS-B evaluating the impact of vutrisiran on ACM and recurrent CV events among patients identified by investigators as having experienced disease progression while being treated with tafamidis. Also at the Heart Failure 2025 Congress, Alnylam will present the study design and rationale for TRITON-CM, a Phase 3, randomized, double-blind, study of nucresiran in patients with ATTR-CM. Nucresiran is an investigational next-generation RNAi therapeutic targeting TTR that has been shown to deliver rapid knockdown of TTR greater than 95% with twice-annual dosing in a Phase 1 study. TRITON-CM is an event-driven CV outcomes trial with a primary endpoint of composite ACM and CV events. The study is on track to initiate in the first half of 2025 and will enroll approximately 1,200 patients with wild-type or variant TTR and confirmed cardiomyopathy, including those receiving background stabilizer therapy. Additional details of the study’s secondary endpoints and key inclusion and exclusion criteria will be shared on Monday, May 19. AMVUTTRA® (vutrisiran) was approved by the U.S. Food and Drug Administration (FDA) and the Brazilian Health Regulatory Agency (ANVISA) for treatment of the cardiomyopathy of wild-type or hereditary transthyretin-mediated amyloidosis in adults. The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending the approval of vutrisiran for the same indication. A formal regulatory decision by the European Commission of the EMA is expected by the third quarter of 2025. Vutrisiran is currently under review for the treatment of ATTR-CM by the Japanese Pharmaceuticals and Medical Devices Agency (PMDA). Alnylam remains on track to proceed with additional global regulatory submissions for vutrisiran in 2025 and beyond. For additional information on Alnylam’s presentations at the Heart Failure 2025 Congress, please visit Capella. Indications and Important Safety Information Indications Approved by the U.S. FDA AMVUTTRA® (vutrisiran) is indicated for the treatment of the: cardiomyopathy of wild-type or hereditary transthyretin-mediated amyloidosis (ATTR-CM) in adults to reduce cardiovascular mortality, cardiovascular hospitalizations and urgent heart failure visits. polyneuropathy of hereditary transthyretin-mediated amyloidosis (hATTR-PN) in adults. Important Safety Information Reduced Serum Vitamin A Levels and Recommended Supplementation AMVUTTRA treatment leads to a decrease in serum vitamin A levels. Supplementation at the recommended daily allowance (RDA) of vitamin A is advised for patients taking AMVUTTRA. Higher doses than the RDA should not be given to try to achieve normal serum vitamin A levels during treatment with AMVUTTRA, as serum vitamin A levels do not reflect the total vitamin A in the body. Patients should be referred to an ophthalmologist if they develop ocular symptoms suggestive of vitamin A deficiency (e.g., night blindness). Adverse Reactions In a study of patients with hATTR-PN, the most common adverse reactions that occurred in patients treated with AMVUTTRA were pain in extremity (15%), arthralgia (11%), dyspnea (7%), and vitamin A decreased (7%). In a study of patients with ATTR-CM, no new safety issues were identified. For additional information about AMVUTTRA, please see the full U.S. Prescribing Information (revised March 2025) About AMVUTTRA® (vutrisiran) AMVUTTRA® (vutrisiran) is an RNAi therapeutic that delivers rapid knockdown of variant and wild-type transthyretin (TTR), addressing the underlying cause of transthyretin (ATTR) amyloidosis. Administered quarterly via subcutaneous injection, vutrisiran is approved and marketed in more than 15 countries for the treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis (hATTR-PN) in adults. In Europe, it is administered as a subcutaneous injection once every three months, either by a healthcare professional, or self-administered by patients or their caregivers. Vutrisiran is also in development for the treatment of ATTR amyloidosis with cardiomyopathy (ATTR-CM), which encompasses both wild-type and hereditary forms of the disease. About ATTR Transthyretin amyloidosis (ATTR) is an underdiagnosed, rapidly progressive, debilitating and fatal disease caused by misfolded transthyretin (TTR) proteins, which accumulate as amyloid deposits in various parts of the body, including the nerves, heart and gastrointestinal tract. Patients may present with polyneuropathy, cardiomyopathy, or both manifestations of disease. There are two different forms of ATTR – hereditary ATTR (hATTR), which is caused by a TTR gene variant and affects approximately 50,000 people worldwide, and wild-type ATTR (wtATTR), which occurs without a TTR gene variant and impacts an estimated 200,000 – 300,000 people worldwide.1-4 About RNAi RNAi (RNA interference) is a natural cellular process of gene silencing that represents one of the most promising and rapidly advancing frontiers in biology and drug development today. Its discovery has been heralded as “a major scientific breakthrough that happens once every decade or so,” and was recognized with the award of the 2006 Nobel Prize for Physiology or Medicine. By harnessing the natural biological process of RNAi occurring in our cells, a new class of medicines known as RNAi therapeutics is now a reality. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise Alnylam’s RNAi therapeutic platform, function upstream of today’s medicines by potently silencing messenger RNA (mRNA) – the genetic precursors – that encode for disease-causing or disease pathway proteins, thus preventing them from being made. This is a revolutionary approach with the potential to transform the care of patients with genetic and other diseases. About Alnylam Pharmaceuticals Alnylam (Nasdaq: ALNY) has led the translation of RNA interference (RNAi) into a whole new class of innovative medicines with the potential to transform the lives of people afflicted with rare and prevalent diseases with unmet need. Based on Nobel Prize-winning science, RNAi therapeutics represent a powerful, clinically validated approach yielding transformative medicines. Since its founding in 2002, Alnylam has led the RNAi Revolution and continues to deliver on a bold vision to turn scientific possibility into reality. Alnylam has a deep pipeline of investigational medicines, including multiple product candidates that are in late-stage development.

Pfizer leans on cost cuts to offset falling revenue

Bengaluru: Pfizer said on Tuesday it would generate $1.7 billion more in savings from cost cuts to its manufacturing and research operations, highlighting its operational efficiency even as it reported lower first-quarter revenue due to declining sales of its COVID-19 treatment Paxlovid. Chief Executive Albert Bourla, speaking on a conference call with investors, said the drugmaker's story over the next three years would not be one of strong revenue growth, given looming patent expirations on top products, but rather one of earnings growth. The company reaffirmed its full-year forecast, and shares were up nearly 4 per cent. Pfizer also said it had measures in place to mitigate the impact of potential tariffs on pharmaceuticals by the Trump administration, including possibly shifting some production to existing facilities in the United States. "We have huge manufacturing capacity right now in the U.S., particularly for everything that is injectable," Bourla said. "If there is a need, it's clearly there, and without the need to build new facilities." Pfizer has 10 manufacturing sites and two distribution centers in the United States, employing nearly 10,000 people. While the rates and timing of tariffs on the pharma sector are unclear, analysts expect that companies will have to absorb any near-term costs if they are imposed. Washington has launched an investigation into the industry, laying the groundwork for possible levies. Bourla in an interview said the industry is hoping the Trump administration will focus more on medicines like those the World Health Organization has designated as essential, which tend to be off-patent and produced mostly in China and India. "I think that's where the problem is. It's not if an obesity drug is made in Ireland," he said. LEANING ON COST SAVINGS The company said it now expects about $7.7 billion in savings by the end of 2027 from its cost-cutting programs. That includes an additional $500 million in R&D savings, which at least two investors said could reflect Pfizer's recent decision to stop development of its experimental weight-loss pill danuglipron. "The cost savings are real, it does help drive better bottom line performance," said Brian Mulberry, portfolio manager at Zacks Investment Management, which owned 2.44 million Pfizer shares at the end of 2024. "We just want to know where that top-line growth is going to come from." Not from COVID antiviral Paxlovid, apparently. Sales of the two-drug treatment were $491 million, well short of analysts' already diminished expectations of $794.3 million, according to LSEG data. Analysts significantly cut their Paxlovid sales expectations in recent weeks due to a relatively small winter wave of COVID-19 in the U.S. On an adjusted basis, Pfizer earned 92 cents per share in the first quarter, topping analysts' expectations by 26 cents, helped by cost cuts and a lower tax rate. Despite the earnings beat, Pfizer is still forecasting a full-year adjusted profit of $2.80 to $3.00 per share on revenue of $61 billion to $64 billion. CFO David Denton said Pfizer was "currently trending toward the upper end" of its profit forecast. Revenue in the quarter fell 8 per cent from a year ago to $13.72 billion and missed analysts' expectations of $13.91 billion. Potential tariffs could add to existing pressure for Pfizer. Investors have been pushing the company to bring new drugs to market that could make up for revenue likely to be lost from some top-selling medicines nearing the end of patent protection. Zacks' Mulberry said the company has done well at becoming more productive on the manufacturing side. "That's where they're finding a bulk of the savings at this point," he said, "but I don't see the next kind of really big pop in revenue." Even the drugs that outperformed Wall Street expectations in the first quarter face headwinds. Sales of its heart disease drug, sold under the brand names Vyndaqel and Vyndamax, were $1.49 billion, above estimates of $1.29 billion. But the company said it is already seeing the impact of new competition, which it expects to continue through the year. Pfizer's vaccine business could also face greater regulatory scrutiny under the new Health Secretary Robert F. Kennedy Jr., a longtime vaccine skeptic. COVID vaccine Comirnaty, which Pfizer makes with German partner BioNTech, brought in sales of $565 million. Analysts were expecting $331.7 million for the shot in the first quarter.
