CEO letter

This is the first quarterly report we share as a Nasdaq First North company – an important milestone in the history of Cereno. Overall, the second quarter of 2023 can be summarized as an important period for the company's growth and long-term strategy. In addition to the business activities, the development of our whole portfolio has purposely proceeded forward. We have also reported significant news for our CS1 candidate that has indicated a remarkable potential for effect in patients with PAH. The three innovative drug candidates in our portfolio are all taking important steps toward the ultimate goal of improving the quality of life as well as prolonging life for people with common and rare cardiovascular disease.

CS1 shows remarkable pulmonary pressure reduction in a PAH patient
We shared the remarkable outcome of a patient case study earlier this summer from the ongoing study. The investigator who initiated the case study was intrigued by the effect of CS1 and how convenient the daily remote monitoring using CardioMEMS HF System was. In only 12 weeks of treatment with CS1, the patient’s PAH disease improved noticeably. We noted that CS1 showed a 30% reduction in PAH and a 20% increase in cardiac output. The patient’s overall functional status was changed from NYHA/WHO functional class II to I at the end of the treatment period, meaning that she had next to normal functional physical capacity. This patient had been on a stable standard of care treatment for PAH for the last three years without achieving the same results, which strongly speaks for CS1’s effect on PAH. With these positive initial findings, we are optimistic about the Phase II study outcome and CS1’s potential.

Two new clinics open to complete patient recruitment in the CS1 study
During the second quarter, we have seen further significant progress in our patient recruitment with 25 patients enrolled and 16 patients in active treatment to date. Although this is highly positive, it is still lower than the patient recruitment pace anticipated. We have, therefore, now initiated the activation of two new specialist clinics with large capacities. We are highly optimistic about an increased recruitment pace as the new clinics have already identified suitable patients before activation, and more patients are also lined up for screening in September and October at existing clinics. We believe that opening the two new clinics with known large capacities will further support patient recruitment to complete the study and mitigate any further changes to the study timelines. The study’s top-line results are now estimated to be reported during Q1 2024.

Data quality control of CardioMEMS initiated to obtain CS1 efficacy data in Q4 2023
We are excited to be able to share that we have launched an initiative for data quality control of CardioMEMS HF System. Our discussions for this initiative were triggered by remarkable positive findings on CS1 efficacy on PAH as was observed in the patient case study reported in June. With this quality control, we aim to provide an opportunity to optimize patients' study protocol adherence and data transfer quality of CardioMEMS, which in turn will support a higher level of standardization of study data. The intention is to create an optimal, conclusive data set for when the top-line results are analyzed with a strong, clear indication of the effect of CS1 as measured by the CardioMEMS HF System. Our aim is to provide a report from the data quality control during Q4 2023, which will then also include efficacy data on more than half of the study population receiving CS1. We are eager to see the results as CS1 has thus far indicated to be an efficacious treatment alternative in PAH.

Preclinical candidates continue to progress
The extended preclinical development programs of CS014 and CS585 have continued to progress during the quarter in collaboration with the University of Michigan. In April, we signed an agreement with the University of Michigan to obtain exclusive rights for further development and commercialization of CS585. The drug candidates show promising data as we continue development toward Phase I studies.

We are especially looking forward to advancing our drug candidate CS014, in development for the prevention of thrombosis, arterial and venous, over the upcoming months. The next major milestone for the program is to obtain a permit from the Swedish Medical Products Agency (Läkemedelsverket) and the Ethical Review Authority (Etikprövningsmyndigheten) to allow us to start a Phase I study in H1 2024.

The development program of CS585 is progressing with the aim of working toward completing the preclinical program in 2024.

Leveraging our exposure to potential industrial partners
We are continuing to actively participate in scientific congresses and medical meetings to increase the reach of our innovative drug candidates to the scientific community and industrial potential development partners to leverage Cereno’s business development objectives for our programs. During the last few months, we presented preclinical data at the scientific conference Vascular Discovery 2023: From Genes to Medicine hosted by the American Heart Association, in Boston, Massachusetts, US, May 10-13, 2023, the European Hematology Association (EHA) 2023 Hybrid Congress in Frankfurt, Germany, on June 8-11, 31st Congress of the International Society on Thrombosis and Haemostasis (ISTH 2023 Congress), in Montreal, Canada on June 24-28, 2023; as well as the upcoming ESC Congress 2023 hosted by the European Society of Cardiology, in Amsterdam, Netherlands, on August 25-28, 2023. Our CMO Björn Dahlöf was also invited to speak at the invitation-only event 8th Annual Drug Discovery & Development Symposium arranged by the Pulmonary Vascular Research Institute (PVRI) on July 10-11, 2023, to talk about HDAC inhibition in PAH in general, and CS1 in PAH, in particular, as well as the ongoing study. In addition, we have several new abstracts and publications on preclinical data in preparation over the coming months.

Initiating the next growth period for the company
On June 14, 2023, we rang the Nasdaq bell marking the start of the trading of the Cereno share on the marketplace Nasdaq First North Growth Market. As we approach several key milestones for our portfolio and expect high interest from the national and international investor community, the uplisting from Spotlight Stock Market to Nasdaq First North Growth Market is a natural next step in Cereno’s growth journey. In connection with the move to a new marketplace, we carried out a rights issue enabling us to proceed with further development of our promising drug candidates.

We are evolving our team to support the new requirements that come with a Nasdaq listing. A new CFO, Eva Jagenheim, joins us on August 28, bringing a wealth of experience and valuable financial expertise from previous roles in public biotech companies.

We are very excited about the progress of our portfolio over the last period and especially the encouraging efficacy findings on CS1 from our patient case in our lead program in PAH. We are now set to drive our ambitions forward with the aim to offer innovative treatments that could potentially significantly improve the quality of life and life expectancy for patients with common and rare cardiovascular disease.

Thank you for your continued support of our exciting journey.

Sten R. Sörensen, CEO

About Cereno Scientific AB

Cereno Scientific is a clinical-stage biotech company within cardiovascular diseases. The lead drug candidate, CS1, is a Phase II candidate in development for the treatment of the rare disease pulmonary arterial hypertension (PAH). CS1 is an HDAC (histone deacetylase) inhibitor that acts as an epigenetic modulator with pressure-reducing, reverse-remodeling, anti-inflammatory, anti-fibrotic and anti-thrombotic properties, all relevant for PAH. A clinical Phase II study is ongoing to evaluate CS1’s safety, tolerability, and efficacy in patients with PAH. A collaboration agreement with global healthcare company Abbott allows Cereno to use their cutting-edge technology CardioMEMS HF System in the study. Cereno also has two promising preclinical drug candidates in development for cardiovascular disease through research collaborations with the University of Michigan. Drug candidate CS014 is a novel HDAC inhibitor with epigenetic effects, selected for prevention of thrombosis as target indication. In preclinical studies it has been documented to regulate platelet activity, fibrinolysis and clot stability for prevention of thrombosis without increased risk of bleeding. Thrombosis prevention in venous or arterial and cardiovascular disease has been selected as the first indication area for CS014. Drug candidate CS585 is a prostacyclin receptor agonist that has been documented in preclinical studies to target the IP receptor for prevention of thrombosis without increased risk of bleeding. The company is headquartered in Gothenburg, Sweden, and has a US subsidiary Cereno Scientific Inc. based in Kendall Square in Boston, Massachusetts, US.
