New Risk • May 06
New major risk - Revenue size The company makes less than US$1m in revenue. This is considered a major risk. Companies with a small amount of revenue are most likely businesses that have not yet released a product to market or are simply a very small company without a wide reach. Either way, risk is elevated with these companies because there is a chance the product may not come to fruition or the company's addressable market or demand may not be as large as expected. In addition, if the company's size is the main factor, it is less likely to have many investors and analysts following it and scrutinizing its performance and outlook. Currently, the following risks have been identified for the company: Major Risk Revenue is less than US$1m. Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$145m net loss in 3 years). Share price has been volatile over the past 3 months (14% average weekly change). Shareholders have been diluted in the past year (16% increase in shares outstanding). Significant insider selling over the past 3 months (US$2.2m sold). Announcement • May 04

New minor risk - Shareholder dilution The company's shareholders have been diluted in the past year. Increase in shares outstanding: 16% This is considered a minor risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$216m net loss in 3 years). Share price has been volatile over the past 3 months (14% average weekly change). Shareholders have been diluted in the past year (16% increase in shares outstanding). Significant insider selling over the past 3 months (US$3.2m sold). New Risk • Mar 31
New minor risk - Share price stability The company's share price has been volatile over the past 3 months. It is more volatile than 75% of American stocks, typically moving 6.5% a week. This is considered a minor risk. Share price volatility indicates the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. It also increases the risk of potential losses in the short term as the stock tends to have larger drops in price more frequently than other stocks. Currently, the following risks have been identified for the company: Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$203m net loss in 3 years). Share price has been volatile over the past 3 months (6.5% average weekly change). Significant insider selling over the past 3 months (US$3.2m sold). Price Target Changed • Mar 31

ORX750 showed clinically meaningful and statistically significant improvements in mean sleep latency at the first two doses evaluated (1.0 mg and 2.5 mg) in the Maintenance of Wakefulness Test (MWT) compared to placebo. More specifically, the 2.5 mg dose was shown to restore normative wakefulness2 with a mean sleep latency of 32 minutes as measured by the MWT. ORX750 was also shown to have a favorable safety and tolerability profile with no observations of frequently reported on-target adverse events (AEs) associated with other OX2R agonists, and no cases of hepatotoxicity or visual disturbances across all three dose levels tested (1.0 mg, 2.0 mg, and 2.5 mg), as of the data cutoff date.1 Based on the interim data, the Company plans to rapidly advance ORX750 into Phase 2 studies in patients with narcolepsy type 1 (NT1), narcolepsy type 2 (NT2), and idiopathic hypersomnia (IH) beginning in the fourth quarter of 2024. The Phase 1 clinical study is an ongoing first-in-human, randomized, placebo-controlled study designed to evaluate the safety, tolerability and pharmacokinetics (PK) of single-ascending doses (SAD) and multiple-ascending doses (MAD) of ORX750 in healthy adult subjects. In parallel to the SAD, a placebo-controlled cross-over pharmacodynamic (PD) assessment is being performed utilizing the MWT and Karolinska Sleepiness Scale (KSS) in acutely sleep-deprived healthy adult subjects with the goal of rapidly generating early efficacy data to inform dosing for planned studies in patients. As of September 10, 2024, the study has completed three SAD cohorts of healthy volunteers (27 active, 9 placebo) with doses of 1.0 mg, 2.0 mg, and 2.5 mg, and has advanced through two cohorts within the cross-over assessment of acutely sleep-deprived healthy volunteers with doses of 1.0 mg (n=8) and 2.5 mg (n=8), administered as a single oral dose. Dosing in the MAD portion of the study is also ongoing. Recent Insider Transactions Derivative • Aug 26

Centessa Pharmaceuticals plc Announces Open IND for ORX750 Centessa Pharmaceuticals plc announced that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug application (IND) to initiate a Phase 1 first-in-human, clinical trial of ORX750 for the treatment of narcolepsy. ORX750 is an investigational, orally administered, highly potent and selective orexin receptor 2 (OX2R) agonist designed to directly target the underlying pathophysiology of orexin neuron loss in narcolepsy type 1 (NT1), with potential applicability to narcolepsy type 2 (NT2), idiopathic hypersomnia (IH), and other sleep-wake disorders with normal orexin levels. The Phase 1 study will evaluate the safety, tolerability and pharmacokinetics of single-ascending doses (SAD) and multiple-ascending doses (MAD) of ORX750 in healthy adult subjects. In parallel to the SAD, a cross-over pharmacodynamic (PD) assessment will be performed utilizing the Maintenance of Wakefulness Test (MWT) and Karolinska Sleepiness Scale (KSS) in acutely sleep-deprived healthy adult subjects which is intended to provide proof-of-concept data to enable dose selection for NT1, NT2 and IH indications. The study has a maximum exposure limit specified by the FDA which the Company believes significantly exceeds the predicted efficacious doses of ORX750 in indications associated with or without orexin loss; therefore, the Company does not expect this limit to affect any of the planned clinical development activities for ORX750. The Company expects to commence dosing of the Phase 1 study in healthy volunteers imminently, and proof-of-concept data are anticipated in the second half of 2024. ORX750 is an investigational, orally administered, highly potent and selective orexin receptor 2 (OX2R) agonist designed to directly target the underlying pathophysiology of orexin neuron loss in narcolepsy type 1 (NT1). ORX750 has been shown to potently activate the OX2R with an in vitro EC50 of 0.11 nM and 9,800-fold selectivity over the human orexin receptor (hOX1R). ORX750 is Centessa’s first orexin product candidate being developed for the treatment of narcolepsy with potential expansion into narcolepsy type 2 (NT2), idiopathic hypersomnia (IH) and other sleep-wake disorders.

World Sleep Congress Releases an Abstract Submit by Centessa Pharmaceuticals plc On August 22, 2023, the World Sleep Congress 2023 released an abstract submitted by Centessa Pharmaceuticals Plc. containing preclinical data on ORX750, the company's orally administered, selective orexin receptor 2 (OX2R) agonist in development for the treatment of narcolepsy and other sleep disorders. The company will present the abstract in an oral presentation on October 25, 2023. Introduction: Narcolepsy Type 1 (NT1) is a rare neurological disease caused by the profound loss of orexin-producing neurons. Orexin (also called hypocretin) is a neurotransmitter that regulates wakefulness, arousal, and energy homeostasis via activation of Orexin Receptor-1 (OX1R) and -2 (OX2R). Orexin agonists are designed to directly address the underlying disease pathology of NT1 to restore orexin neurotransmission in the brain. The orexin/ataxin-3 (Atax) mouse model of NT1 recapitulates key features of the human disorder, such as orexin loss, inability to sustain wakefulness, and cataplexy (emotionally triggered, transient loss of muscle tone). Here it present ORX750, a novel, orally available, brain penetrant, OX2R selective agonist. ORX750 was developed using structure-based drug design with an OX2R stabilized receptor (StaR®) protein and high-resolution protein crystallography. Materials and Methods: In vitro calcium mobilization (FLIPR), ß-arrestin recruitment, and inositol-phosphate accumulation assays were performed in Chinese hamster ovary (CHO) cells stably expressing human recombinant OX1R or OX2R. Electrophysiological recordings were performed on slices of the ventral tuberomammillary nucleus (TMN) from mouse hypothalamus; effects on membrane potential were measured in the presence of 1 micromolar tetrodotoxin to block neuron firing. In vivo efficacy for enhancing wakefulness was evaluated in wild type (WT) and Atax mice during their rest phase using PiezoSleep, a rapid, non-invasive method for classifying sleep and wakefulness by unsupervised machine learning on physiologically relevant readouts, including body movement and breath rate. Electroencephalogram (EEG), electromyogram (EMG), and video recordings were used in Atax mice during their active phase to evaluate effects at 0.3-10 mg/kg on arousal states and cataplexy. Results: ORX750 behaved as a potent full agonist at human OX2R (EC50=0.11 nM) relative to the native ligand orexin A (OXA; EC50=0.035 nM) and showed 9,800-fold selectivity over human OX1R (EC50=1100 nM) in the FLIPR assay. Biased agonism was not detected by measurement of b-arrestin recruitment at OX2R in comparison to OXA. ORX750 depolarized membrane potential (EC50=5.0 nM, max DmV=9.5) in whole cell current-clamp recordings in the TMN. In the PiezoSleep assay, in which wakefulness readouts are highly correlated with EEG/EMG-defined wakefulness, ORX750 increased time awake and the consolidation of wakefulness vs. vehicle in a dose-related manner when administered to WT and Atax mice during the rest phase. Increased sensitivity to these wake-promoting effects was observed in Atax vs. WT mice. In Atax mice, ORX750 increased time awake; consolidated wakefulness; increased EEG gamma power during wakefulness; reduced cataplexy occurrences; and increased latencies to sleep and cataplexy in a dose-related manner during the active phase using the EEG/EMG/video assay. At the lowest dose tested (0.3 mg/kg) and compared to vehicle, the latency to sleep was 2.3 h vs. 0.69 h and the latency to cataplexy was 2.7 h vs. 1.3 h. Conclusions: ORX750 is an oral, highly potent, and selective OX2R agonist with the potential to treat patients with primary symptoms of NT1, as well as reduce excessive sleepiness in those presenting sleep/wake disorders with normal orexin levels.

Centessa Pharmaceuticals Announces Dosing of First Subject in Registrational PRESent-2 Study Evaluating SerpinPC for the Treatment of Hemophilia B Without Inhibitors Centessa Pharmaceuticals plc announced the dosing of the first subject in its registrational PRESent-2 study of SerpinPC for the treatment of hemophilia B without inhibitors. The dosing phase of PRESent-2 follows a minimum 12-week observation period during which prospective baseline data of the subject’s disease status under their current therapy are collected to support regulatory review of the benefit and risk profile of SerpinPC. SerpinPC is an investigational subcutaneously administered novel inhibitor of activated protein C (APC) being developed as a potential treatment for hemophilia B, with or without inhibitors. The PRESent-2 study (AP-0102) is a Phase 2b, global, open-label, seamless adaptive design study to investigate the efficacy and safety of subcutaneous dosing of SerpinPC every week, every 2 weeks, or every 4 weeks in approximately 120 adult (aged 18 to =65 years) or adolescent (aged =12 to <18 years) male subjects with severe hemophilia A (with or without inhibitors) or moderately severe to severe hemophilia B (without inhibitors). PRESent-2 consists of 3 parts: a 24-week randomized dose-justification phase (Part 1), a 24-week dose-confirmatory phase (Part 2), and a further 24-week extension phase (Part 3) for subjects who complete either Part 1 or Part 2. Subjects must have undergone a minimum period of prospective observation (at least 12 weeks for Part 1 or 24 weeks for Part 2) under their current therapy (either on-demand or prophylaxis factor replacement) before switching to SerpinPC treatment. The primary efficacy endpoint for the study is the rate of treated bleeds (expressed as an annualized bleeding rate (ABR)) in the observation period compared to the first 24 weeks treated with SerpinPC. The Company expects to begin dosing in its registrational PRESent-3 (AP-0103) study for subjects with hemophilia B with inhibitors this year. New Risk • Jul 06
