The final quarter of the year saw a number of changes, both in portfolio companies and to Karolinska Development. The clinical development work by several of our portfolio companies is now reaching the very advanced stage, and this is particularly true for our most recent addition, BOOST Pharma, which is engaged in a dialogue with the FDA regarding phase 3 studies forming the basis for registration. AnaCardio and Umecrine Cognition have both successfully completed financing rounds, with the former raising a total of SEK 205 million that will enable it to continue its ongoing clinical studies after promising interim findings. Karolinska Development has taken advantage of the advances by the OssDsign medtech company to divest shares in the company and thereby realise the profit on just under half of its proprietary holding. This strengthened liquidity will enable us to create substantial value going forward.
Our portfolio company, BOOST Pharma, has successfully completed a pre-IND advisory meeting with the US Food and Drug Administration (FDA) regarding the development plan for the company's cell therapy which aims to treat children with the rare bone disease, Osteogenesis Imperfecta. The company will now, based on the positive feedback, begin preparations for a phase 3 clinical development program that will be conducted in the USA and in Europe. The positive outcome of the pre-IND meeting will also trigger the second tranche of Karolinska Development's and Industrifonden's investment in BOOST Pharma in line with an earlier agreement, and we are delighted to increase our ownership in this innovative project which is rapidly progressing towards registration trials.
After the quarter's end, our portfolio company, AnaCardio, secured SEK 205 million in a financing round and welcomed Novo Holdings, Pureos Bioventures and Sound Bioventures as new investors. AnaCardio simultaneously reported positive results from the first part of the company's clinical phase 1b/2a studies of its candidate drug, AC01, in patients with heart failure and reduced ejection fraction. The financing will be used to complete the trial and to prepare and initiate start-up activities for a subsequent phase 2b study.
In November, Umecrine Cognition presented positive interim data from an ongoing clinical phase 1b/2a study of golexanolone in patients with primary biliary cholangitis (PBC). In December, the company raised SEK 23.8 million through a convertible loan which will be used to finance the ongoing clinical trial with the aim of completing the study in the first half of 2025 – a milestone which, in the event of positive results, could result in a substantial increase in the value of the pharmaceutical project.
Umecrine has also presented preclinical data for golexanolone showing retained dopamine signalling in Parkinson's disease, which is a progressive disease caused by the loss of nerve cells in the brain that produce the signalling substance, dopamine, which leads to various symptoms that reduce the patient's well-being and quality of life.
In November, the Modus Therapeutics portfolio company secured access to bridge financing of up to SEK 5 million from Karolinska Development, which is the company's largest shareholder. The funding enabled Modus Therapeutics to initiate the clinical phase 2a study of its candidate drug, sevuparin, in chronic kidney disease with anaemia in December. The study is being conducted in Italy and is expected to recruit between

50 and 60 patients (parts 1 and 2). The first part of the study has an estimated completion within the first half of 2025.
In October, the SVF Vaccines portfolio company announced positive results from a clinical phase 1 study of a universal COVID-19 vaccine, SVF-002. The study reported positive clinical safety and immunogenicity data at The International Society for Vaccines' annual meeting in Seoul, South Korea. The results of the study constitute an important milestone for the company in that they validate SVF Vaccines' development platform, which comprises a portfolio of therapeutic and prophylactic vaccines that can, potentially, both prevent disease and treat already infected patients.
Karolinska Development divested 4.6 million shares in its portfolio company, OssDsign, thereby strengthening the investment company's own liquidity by almost SEK 40 million. Karolinska Development is a long-term owner of OssDsign and was involved in the company's listing on the Nasdaq First North Growth Market in Stockholm. We continue to have every confidence in OssDsign's ability to successfully increase market penetration for its unique bone graft and have retained a holding of around 5,000,000 shares in the wake of the divestment.
In December, Professor Hans Wigzell resigned his role as Chairman of the Board of Karolinska Development at his own request, after having been an important and instrumental force in the company in a variety of positions since its foundation. The Board of Directors has appointed as his successor, Board Member Ben Toogood, who will take over the role of Chairman until the next General Meeting.
We have conducted a strategic review during the quarter and identified opportunities for enhancing operational efficiency. The review resulted in organisational changes that entailed a total of three people were laid off – a change that is estimated to reduce the company's personnel costs by approximately 20%. It is, of course, regrettable when competent and popular employees are required to leave, but we are convinced that these changes prompted by our strategic review are in the long-term interests of the company.
The enhanced operational efficiency will secure the sustainability of our portfolio management and ensure that we make optimum use of our financial resources, enabling us to provide the best possible support for our portfolio companies and to generate value for our shareholders

Karolinska Development's investments in therapeutic companies are conducted in syndicates with other professional life science investors, normally until proof-of-concept is demonstrated in phase 2 trials, at which point different exit options are evaluated. When engaging in MedTech companies, the business model is to finance the companies until they show a positive operating profit.
The portfolio, per December 31, 2024, consisted of eleven companies focused on developing innovative treatment methods for severe or life-threatening diseases where there is currently a great need and there is a lack of effective treatment alternatives. Nine of the portfolio companies have drug candidates in ongoing or planned clinical trials and two companies have MedTech products in commercial phases. During the period 2025–2026, two portfolio companies are expected to present data from phase 1 studies and three portfolio companies are expected to present data from phase 2 studies. Additionally, Dilafor and BOOST Pharma are preparing to start phase 3 studies. These study results have the potential to significantly increase the opportunities for attractive divestments or license transactions. Comparable drug candidates have in recent years been out licensed or sold at contract values that have amounted to billions (SEK) for the individual projects.
In addition to the portfolio companies, Karolinska Development has interests in one other life science company, Forendo Pharma, in the form of an earn-out agreement with the acquirer Organon. The agreement stipulates significant milestone payments, provided milestones are met, in both the drug development phase and the commercial phase.

Dilafor (Solna, Sweden) is developing tafoxiparin, a heparin analogue, aimed at priming spontaneous onset of labor leading to a normal vaginal delivery and minimizing the risk for maternal and fetal complications associated with labor induction. Over 30 percent of all pregnant women undergo induction in labor, with induction methods such as prostaglandins and oxytocin, requiring fetal and maternal surveillance in hospital due to high risk of complications for both mother and fetus. Clinical guidance for labor induction have recently been revised to encourage delivery as early as gestational week 39 in the US and weeks 40–41 in Europe, to reduce the risk of complications such as stillbirth, neonatal complications and operative deliveries leading to improved maternal and neonatal outcomes The new guidance will increase the number of deliveries requiring initiation of labor, and thus new, safer treatment options are essential in obstetric care. Tafoxiparin is a patented substance that supplements the remodeling process of the cervix and uterus required for a natural spontaneous onset of labor. Tafoxiparin is planned to be safely administered at home, freeing up hospital beds and resources that would otherwise be required for the induction process.
Tafoxiparin has been shown to be safe for both mother and child in a Phase 2a clinical trial with 263 pregnant women. A Phase 2b trial with 170 first-time mothers undergoing priming of labor showed significant results in the highest dose group and in an extension of the Phase 2b trial with 164 women, positive results were also shown in lower doses. Dilafor has successfully completed meetings with the US FDA and the European Health Agencies and is now preparing the Phase 3 development of tafoxiparin.
Over 30 percent of all pregnant women need labor induction. The current standard treatment includes administration of prostaglandins and oxytocin. Frequently the induction fails, leading to slow progress of labor, operative deliveries, or other maternal and fetal complications. Market analyses show that a drug with a good effect on initiation of labor has the potential to reach annual sales over USD 1 billion in the US market alone.
• Start of Phase 3 study with tafoxiparin for priming of labor.

BOOST Pharma (Copenhagen, Denmark) is developing a first-in-class and potentially groundbreaking cellbased treatment of the rare bone disease osteogenesis imperfecta (OI), also known as brittle bone disease. OI is a congenital condition that is caused by gene mutations that code for bone formation and lead to fragile bones, constant fractures and bone deformity leading to much pain, stunted growth and limited mobility.
BOOST Pharma's novel cell therapy is based on mesenchymal stem cells (MSCs), which are stem cells with high bone-forming capabilities. In September 2024, BOOST Pharma presented positive top line results from BOOSTB4, which is a phase 1/2 clinical study. The results showed that the treatment was safe and well tolerated both when administered before and after birth. The results also showed that fracture rates were reduced by over 75 percent, up to twelve months after the last dose.
A previous study, a human proof-of-concept study with four children with moderate to severe types of OI, also showed great promise; A significant reduction of fractures was observed; the children followed their own growth curve, and grew in length faster, compared to other OI patients, and the cells showed great safety.
The cell therapy is uniquely positioned in that treatment can start directly at diagnosis, either at the prenatal stage, or after the child is born. By starting treatment early, the benefits for the patient increase in later years. The cell therapy targets the underlying cause of the disease, which is defective collagen production in the bones, while other treatments target symptom relief and management.
BOOST Pharma has received Rare Pediatric Disease designation in the U.S. and Orphan Drug Designation in both the U.S. and EU.
There are very few therapies available and those that exist, such as physiotherapy, surgery, and bisphosphates (BPs), are merely palliative and fail to reduce the frequency of fractures. Generally, OI sufferers have an almost normal life span with severe disabilities due to bone defects and hundreds of painful bone fractures, even during fetal life, causing irreversible damage. Approximately 4,000 children are born each year with severe OI.
A registration-enabling Phase 3 study is expected to start early in 2026.

Umecrine Cognition (Solna, Sweden) is developing golexanolone (GR3207), a candidate drug in a new class of pharmaceuticals that affect the GABA system, the chief inhibitory neurotransmitter in the central nervous system. The GABA system is suspected of being overactivated in liver failure and in other severe inflammatory diseases such as Parkinson's disease, causing very serious clinical symptoms, including cognitive impairments and sleep disturbances. Golexanolone counters the increased activation of the GABA system and has been shown to restore different types of neurological impairments in experimental models.
Umecrine Cognition is developing golexanolone for two indications: Primary Biliary Cholangitis (PBC) and Parkinson's disease. The company has also conducted a phase 2a clinical study of golexanolone in patients with Hepatic encephalopathy (HE), which is a serious neuropsychiatric and neurocognitive condition that occurs in acute and chronic liver damage. The results showed that the drug candidate was well tolerated and exerts a significant effect on brain signaling, with a correlated positive effect on extreme daytime fatigue. Based on these study results, the company has established a plan for the further development of the drug candidate in PBC, where extreme daytime fatigue is one of the disease's most debilitating symptoms that prevents patients from living a normal life. The company is currently conducting a phase 2 study in PBC. Golexanolone has also been tested in preclinical models of Parkinson's disease which showed positive effects on symptoms and neuroinflammation as well as sustained effects on dopamine signaling.
PBC is a rare autoimmune liver disease that attacks the bile ducts and mainly affects women. Common symptoms include fatigue, cognitive impairment, itching and, in more advanced cases, jaundice. The global market for the treatment of PBC was estimated at USD 584 million in 2021 and is expected to grow to USD 3 billion by 2027.
Parkinson's disease is a neurodegenerative disorder that causes severe cognitive impairment and impairs motor functions. Approximately 10 million people worldwide suffer from the disease. Current medications are mainly focused on improving motor functions and there is a lack of treatments for cognitive impairment. The global market for this type of treatment was USD 3.4 billion in 2019 and is expected to grow by over 6 percent per year until 2029.
Topline data from the Phase 2 study of golexanolone in patients with PBC are expected in H1 2025.

Modus Therapeutics AB (Stockholm, Sweden) is developing the drug candidate sevuparin for the treatment of both acute and chronic severe conditions. The company's clinical project portfolio includes anemia associated with chronic inflammation and kidney disease, sepsis/septic shock, and severe malaria.
At the end of 2024, Modus Therapeutics initiated a Phase 2 clinical study to evaluate sevuparin as a treatment for chronic kidney disease with anemia. The study consists of two parts: the first assesses safety and determines dosage levels for sevuparin through single-dose administration to patients with varying degrees of renal impairment, as well as a small reference group of healthy volunteers. The second part will focus on the effects of repeated doses and clinical outcomes, including hemoglobin levels, kidney function, hepcidin levels, and other biomarkers in patients with advanced chronic kidney disease and anemia. Research has shown that elevated hepcidin levels contribute to disrupted iron availability in chronic kidney disease and other chronic inflammatory conditions, worsening anemia associated with these diseases.
Sepsis/septic shock is a life-threatening medical condition for which there are currently no effective medical therapies. Patients with sepsis are at risk of developing multiple organ failure, and in severe cases, death. Data from preclinical animal models and in vitro experiments with human cells have shown that sevuparin may protect blood vessels and counteract plasma leakage during systemic inflammation.
In severe malaria, sevuparin is being developed as an adjunct therapy, administered before standard antimalarial treatment takes effect. Sevuparin is currently being evaluated in a clinical study conducted in collaboration with Imperial College London at trial sites in Kenya and Zambia.
Septic shock is a leading cause of death in intensive care units, with mortality rates often exceeding 30 percent. No specific drug treatment is yet available. This makes the condition one of the costliest to treat in hospital care. In 2019, US healthcare costs for patients with sepsis were estimated at USD 23 billion.
Approximately 10 percent of the world's population is believed to have grade 3-5 chronic kidney disease, and approximately 25 percent of these are expected to have anemia, which equates to approximately 4-5 million patients in the United States alone. Lack of treatment response to today's standard treatments often poses a problem in being able to maintain adequate treatment over time.
The first part of the Phase 2 clinical trial with sevuparin as a treatment for chronic kidney disease with anemia is expected to be completed in the first half of 2025.

AnaCardio (Stockholm, Sweden) is developing a new treatment that enhances the heart's pumping ability in conjunction with heart failure. Heart failure occurs when the heart's ability to pump sufficient blood to meet the body's needs has deteriorated. The underlying condition often involves a weakening of the heart's musculature, resulting in an inability to pump the blood out of the heart's chambers. The condition arises as a sequela of high blood pressure or vasoconstriction. The chronic phase is characterized by diffuse symptoms, such as tiredness or breathlessness, which leads to the illness often being diagnosed at a late stage. Acute heart failure results in an individual's health status becoming critical, necessitating hospitalization. A major issue with existing pharmaceuticals is that they are not designed for long-term treatment.
AnaCardio is developing AC01, a small molecule that mimics the mechanism of action of the peptide hormone ghrelin. Treatment with ghrelin has been shown in previous studies to have a positive effect on the heart's pumping ability and can lead to a significant increase in the volume of blood pumped out of the heart. The drug candidate is being developed to restore the heart's normal muscular function and blood circulation with a new and safer technique. The Company's goal is to develop an oral drug that, in contrast to existing treatments, can affect the underlying cause of the disease. The drug candidate is based on research by Professor Lars Lund at Karolinska Institutet.
It is estimated that more than six million individuals in the US and nearly 100 million globally suffer from heart failure. The risk of developing a cardiovascular disease increases with age, and 10-20 percent of the elderly population is now estimated to suffer from chronic heart failure, which is now the most common reason for hospitalization amongst the elderly. Heart failure not only causes considerable individual suffering, but it also has significant economic consequences for society in the form of both direct costs from in-patient care and indirect costs such as productivity losses. The increased medical need is reflected in the sales value of heart failure treatments, which is expected to increase from USD 6.8 billion in 2021 to USD 18.7 billion by 2028 in the world's seven largest pharmaceutical markets.

PharmNovo (Lund, Sweden) is developing innovative drugs for the treatment of nerve pain (neuropathic pain), that is difficult to trat and often develops into a chronic condition. Nerve pain is one of the most prevalent types of chronic pain and affects up to 10 percent of the population. Common underlying causes include nerve damage from type 2 diabetes, shingles, trauma (including surgery), cancer, and cancer treatments. PharmNovo's lead candidate, PN6047, focuses on allodynia and hyperalgesia, two common forms of nerve pain, affecting 15-20 percent of neuropathic pain patients. Allodynia is pain due to a stimulus that does not usually provoke pain, while hyperalgesia is an increased pain from a stimulus that usually provokes pain. Current treatment options are deemed ineffective and are also associated with significant side-effects; particularly cardiovascular risks, and, with gabapentinoids or conventional opioids, a higher risk of suicide and drug abuse potential.
PharmNovo's novel drug candidate PN6047 targets a different receptor than conventional opiate drugs do; the delta opioid receptor and thereby decreases the chronical pain without the side-effects associated with the currently marketed opioids (constipation, physical dependence and, potentially, fatal respiratory depression). PN6047 has completed a clinical phase 1 study showing that PN6047 is safe and well-tolerated at doses predicted to have clinically relevant effects. The drug candidate does not induce drug abuse behavior in nonclinical test models and indicates the capacity to reduce conventional opioid withdrawal symptoms, according to results from a collaboration with researchers at the University of Washington and the University of Michigan, with financial support from the US National Institute of Drug Abuse (NIDA). PharmNovo is now preparing a phase 2 clinical study which is expected to start in 2025.
The need for improved treatments for nerve pain is enormous. Around 10 percent of the world's population currently suffers from conditions characterized by this form of pain, leading to a severely reduced quality of life for the individual and substantial costs for society – estimated at nearly EUR 440 billion annually in Europe alone. The estimated global market value for nerve pain drugs is nearly USD 6 billion per year and the market for allodynia alone is around USD 1.25 billion per year and is expected to continue to grow, driven by an aging population and increased cancer survival.
The phase 2 study with PN6047 is expected to start in 2025.

SVF Vaccines (Solna, Sweden) develops therapeutic proteins and DNA vaccines against, among other things, hepatitis D and B, as well as vaccines to prevent infections by covid-19 and potential future coronaviruses. Therapeutic vaccines, unlike preventative vaccines, have the potential to cure already infected patients.
Despite the availability of preventative vaccines and antiviral treatments, over 250 million people live with a chronic hepatitis B infection. One million chronic carriers die each year due to complications caused by the virus, such as liver cirrhosis and liver cancer. The closely related hepatitis D virus, that only infects hepatitis Bcarriers, today infects 15-25 million people and exacerbates the progression of the disease.
SVF Vaccines uses a proprietary immunotherapy to produce a specific form of antibodies that blocks the ability of the hepatitis virus to invade human cells while also neutralizing the virus, with the vaccine candidate SVF-001. The company has generated promising efficacy data in preclinical animal models and is now preparing a phase 1 study in hepatitis D, that is expected to be initiated in 2026.
The company is also developing SVF-002 against covid-19. Although coronavirus infections are usually mild, some virus types can lead to life-threatening conditions. To meet and prevent severe infections, SVF Vaccines has developed a platform that is expected to enable the production of vaccines against both current and future forms of coronavirus. In October 2024, the company presented positive clinical safety and immunogenicity data from a phase 1 clinical study with the universal vaccine candidate against covid-19, SVF-002. The study was carried out by the OpenCorona consortium in collaboration with Karolinska University Hospital in Stockholm. The positive results are an important milestone and validate SVF Vaccines development platform.
Despite preventive vaccines and antiviral treatments, over 250 million people live with a chronic hepatitis B infection. Each year, one million chronic carriers of the virus die from complications. The hepatitis D virus, which can only infect hepatitis B carriers, currently infects 15–25 million people and exacerbates the disease. The annual global market for hepatitis D is estimated at approximately USD 1 billion and the market for hepatitis B is estimated at USD 5–6 billion. The medical need for therapies for hepatitis B and D is significant.
Phase 1 studies of hepatitis B and D vaccines are expected to be initiated in 2026.

Biosergen (Solna, Sweden) is developing the drug candidate BSG005 as a new potential treatment of systemic fungal infections.
Invasive fungal diseases cause serious and often life-threatening infections that occur when fungi invade tissues and organs. These infections occur primarily in people whose immune systems are compromised due to cancer or treatment with immunosuppressive drugs. While effective pharmaceutical treatments are available, their use is limited due to serious side effects or an increasing incidence of drug resistance. Biosergen's candidate drug, BSG005, has demonstrated a wide spectrum of anti-mycotic effects in preclinical experimental models, and the candidate drug's properties have, to date, been shown to be far superior to those of conventional treatment in terms of effectiveness, toxicity, and pharmacokinetics.
Fungal infections are increasingly becoming a global health concern, associated with high morbidity and mortality as well as devastating socioeconomic consequences. Approximately 90 percent of systemic fungal infection-related deaths are caused by five species: Candida, Aspergillus, Cryptococcus, Pneumocystis, and Mucormycosis.
Biosergen has established a co-development and licensing agreement with one of India's largest pharmaceutical companies, Alkem Laboratories Ltd. In 2024, the first clinical study with BSG005 in patients with invasive fungal infections was initiated in India. Alkem will fund all clinical phase 2 and 3 trials in India except the first clinical trial with 15 patients. The studies are expected to cover up to 70 percent of all patients required for a global regulatory process. Biosergen will retain the rights for the rest of the world outside the Indian market.
Biosergen has been listed on Nasdaq First North Growth Market since 2021.
Fungal infections kill more than 1.5 million globally each year and the numbers continue to increase. In the past 10 years, only one new anti-fungal product has been approved. Despite this, the use of antifungals continues to increase and the WHO has drawn attention to multi-resistance as a serious global health threat. The total sales of antifungals for human use were estimated at approximately USD 16.7 billion in 2020. The Company expects the global annual sales potential for BSG005 to exceed USD 500 million
Read-out of the Phase 1b trial is expected during 2025.

Aprea Therapeutics (Doylestown, USA and Stockholm, Sweden) is focused on developing and commercializing novel drugs to combat various types of cancer by affecting the proteins involved in the ability of tumors to repair damage in their DNA. The company's primary focus is on the development of ATRN-119, a development project that was acquired by the biotech company Atrin Pharmaceuticals in 2022.
ATRN-119 is an orally bioavailable, highly potent and selective small molecule inhibitor of ATR, a protein with key roles in response to DNA damage. ATRN-119 is being evaluated in a phase 1/2a clinical study in cancer patients with malignant solid tumors and defined gene mutations – both as monotherapy and in combination with today's standard treatment. Patient recruitment is ongoing, and the study aims to determine the recommended dose for a Phase 2 clinical trial. The study design was updated in December to include twicedaily dosing, which resulted in an adjustment to the schedule, with results from the dose-escalation Phase 1 portion of the study now expected to be presented in the second half of 2025.
Aprea is also developing APR-1051, an orally bioavailable, highly potent and selective small molecule inhibitor of WEE1, a key regulator of multiple phases of the cell cycle. In March 2024, Aprea Therapeutics received FDA approval of the company's IND application for APR-1051. Aprea has also secured funding of up to USD 34 million through a financing round led by Sphera Healthcare and initiated the first clinical study with APR-1051. In October 2024, preliminary results from a Phase 1 clinical study with APR-1051 in solid tumors were presented. The preliminary results are based on available data from two-thirds of patients and showed that the drug candidate is safe and well tolerated, and that no hematological toxicity was noted.
Aprea has been listed on the Nasdaq Global Select Market in the US since October 2019.
The ability of cancer cells to repair DNA damage, known as DNA Damage Response (DDR), is an emerging therapeutic target for several major pharmaceutical companies. ATR and WEE1 inhibitors have been shown to play a crucial role in this process but are also associated with severe side effects. For ATR inhibitors, toxicity in healthy tissue—primarily in the form of myelosuppression—has limited the potential therapeutic value of the treatment, while WEE1 inhibitors have been linked to significant hematologic, gastrointestinal, and cardiovascular toxicity. There is therefore a great need for highly effective ATR and WEE1 inhibitors with an improved safety and tolerability profile.

Promimic (Gothenburg, Sweden) develops and commercializes HAnano Surface, a surface treatment that is currently used clinically on approximately 1.8 million implants. HAnano Surface is a nanometer-thin coating of hydroxylapatite crystals that stimulates the growth of bone cells. This provides a stronger anchoring in bone tissue and better healing. The surface is unique in that it can be applied to all types of implant materials and geometries, including porous materials and 3D printed structures – including surfaces where traditional thicker HA coating can clog pores.
In the United States, the technology is approved by the FDA, which means that new implants with HAnano Surface can be quickly brought to market via a 510(k) process. This has enabled strong growth – and that the number of approved implants for clinical use continuously increases.
Promimic has a sales office in Austin, Texas and several partnerships for development and commercialization in the US market for orthopedic implants. Currently, the market for spinal implants is the company's strongest segment. The collaboration with the company's customers includes the development and commercialization of products treated with HAnano Surface technology in various application areas.

OssDsign (Uppsala, Sweden) develops and commercializes the next generation of bone replacement products. In September 2023, the Company adopted a new strategy to focus its entire business on the orthobiological market in the US. The background to the strategy shift is the outstanding commercial success of the nanosynthetic bone graft OssDsign Catalyst, an "off the shelf" product with very good scalability and high gross margin.
Over 1.5 million Americans undergo spine surgery each year, about half of whom need a spinal fusion. About 20 percent of all low back pain surgeries, however, fail due to poor fusion between the implant and the spine. When surgeons perform the procedure, they use a combination of screws and metal braces to fix the vertebrae and bone replacement material – a bone graft - to stimulate bone growth. OssDsign Catalyst is an innovative synthetic bone graft consisting of a proprietary nanocrystalline structure of calcium phosphate. OssDsign Catalyst mimics the body's own bone mineral structure and provides a favorable biological environment for rapid and reliable bone formation. OssDsign Catalyst can be produced with high scalability, has an attractive profit margin and great potential in the market for standardized surgical procedures. OssDsign Catalyst received FDA approval in 2020 and launched in the US in August 2021.
The global orthobiologics market was valued at USD 5 billion in 2022. The market segment that OssDsign Catalyst specifically targets is valued at USD 1.8 billion and is expected to have an annual growth rate of 8 percent.

Russia's invasion of Ukraine, as well as the war in Gaza and the related disturbances of sea transport through the Red Sea affect the economy and society as a whole, including Karolinska Development and its portfolio companies. The general downturn in the stock market since 2022 as well as the increase in interest rates since then have shifted the financial market's focus from growth companies to companies with positive operating cash flows, which has led to lower valuations in many previously highly valued growth companies, although we did note an upturn in the financial markets during 2024. This affects Karolinska Development and its opportunities to not only finance its portfolio companies, but also to divest them at a suitable time for Karolinska Development.
The value of listed companies can decline delays in clinical trial programs may occur and the opportunities for refinancing can be hampered. The Board monitors the evolvement of the crises closely and Karolinska Development is working intensively to minimize the impact on the value of our investments and works continuously with different financing alternatives to secure the long-term capital requirement and thereby increase the degree of strategic and operational headroom for the future.

This report has been prepared in accordance with the International Accounting Standard (IAS) 34 Interim Financial Reporting and the Annual Accounts Act. The accounting policies applied to the Investment Entity and the Parent Company correspond, unless otherwise stated below, to the accounting policies and valuation methods used in the preparation of the most recent annual report.
Karolinska Development AB (publ) ("Karolinska Development," "Investment Entity" or the "Company") is a Nordic life sciences investment company. The Company, with Corporate Identity Number 556707-5048, is a limited liability company with its registered office in Solna, Sweden. The Company focuses on identifying medical innovations and investing in the creation and growth of companies developing these assets into differentiated products that will make a difference to patients' lives and provide an attractive return on investment to its shareholders. The sole purpose of investing in such companies is to generate a return through capital appreciation and investment income. These temporary investments, which are not investment entities, are designated "portfolio companies" below.
No new or revised IFRS standards or recommendations from IFRS Interpretations Committee have had significant impact on the Investment Entity.
No related party transactions other than compensation for management and the board have taken place during the reporting period.
Interim period: The period from the beginning of the financial year through the closing date.
Reporting period: January - December 2024.
The Company presents certain financial measures in the interim report that are not defined under IFRS. The Company believes that these measures provide useful supplemental information to investors and the company's management as they allow for the evaluation of the company's performance. Because not all companies calculate the financial measures in the same way, these are not always comparable to measures used by other companies. Therefore, these financial measures should not be considered as substitutes for measures as defined under IFRS.
Portfolio companies: Companies where Karolinska Development has made investments (subsidiaries, joint ventures, associated companies and other long-term securities' holdings) which are active in pharmaceuticals, MedTech, theranostics and formulation technology.
The Portfolio Fair Value is divided into Total Portfolio Fair Value and Net Portfolio Fair Value.
Total Portfolio Fair Value: The aggregated proceeds that would be received by Karolinska Development and KDev Investments if the shares in their portfolio companies were sold in an orderly transaction between market participants at the measurement date.
Net Portfolio Fair Value (after potential distribution to Rosetta Capital) is the net aggregated proceeds that Karolinska Development will receive after KDev Investments' distribution of proceeds to Rosetta Capital.
rNPV: "risk-adjusted net present value" is a method to value risky future cash flows. rNPV is the standard valuation method in the drug development industry, where sufficient data exists to estimate success rates for all R&D phases.
Equity per share: Equity on the closing date in relation to the number of shares outstanding on the closing date.
Net debt: Interest-bearing liabilities (SEK 0.0 million) reduced with cash and cash (SEK 42.0 million).
Equity to total assets ratio: Equity divided by total assets.

1See The Annual Report 2023 Valuation of portfolio companies at fair value, for a description of valuation models. 2Risk-adjusted external valuation model from an independent valuation institute December 2024. The rNPV value from the model adjusted further in order to reflect an assumed split in risk and revenues in conjunction with e.g. a license deal and also to incorporate the financial risk that Umecrine Cognition will not manage to finance fully the final parts of the research program. 3KCIF Co-Investment Fund KB holds listed shares which are valued in accordance with the closing rate on the final trading day of the period and a financial asset, at fair value through profit or loss, attributable to earn-out in the sale of Forendo Pharma. 4KDev Investments AB holds both listed shares which are valued in accordance with the closing rate on the final trading day of the period and unlisted shares which are valued in accordance with the most recent transaction (post-money valuation). Dilafor, which is an unlisted company, accounts for 89% of the total fair value of KDev Investments.

"Potential distribution to Rosetta Capital", SEK 330.8 million, is the amount that KDev Investments according to the investment agreement between Karolinska Development and Rosetta Capital is obliged to distribute to Rosetta Capital from the proceeds received by KDev Investments (KDev Investments Fair Value). The distribution to Rosetta Capital will only happen when KDev Investments distributes dividends. KDev Investments will only distribute dividends after all eventual payables and outstanding debt has been repaid. Following dividends from KDev Investments during 2021 - 2023, all additional investments totaling SEK 43.7 million have been repaid to Rosetta Capital. In addition, SEK 6.7 million has been distributed, which reduces the first SEK 220 million in the waterfall structure. See also the annual report for 2023, note 16, for a description of the agreement with Rosetta Capital.
