N4 Pharma Plc Announces Further Details of its Collaboration with SRI on the Targeting Delivery of RNA into Cells Using Nuvec N4 Pharma plc announced further details of its collaboration with SRI on the targeted delivery of RNA into cells using Nuvec. Following detailed additional analysis, the resulting data are now shaping a new scope of work focused on utilising Nuvec for targeted treatments in oncology. The Company's collaboration combined SRI's targeting molecules with Nuvec successfully delivering therapeutic RNA ("siRNA") payloads to specific cell types, specifically non-small cell lung cancer cells. Key results: Precision targeting achieved: Nuvec particles were functionalised with a targeting molecule binding to a cell surface adhesion molecule (avb6) - a protein found at high levels in epithelial cancers such as lung, breast, prostate and pancreatic adenocarcinomas; Selective uptake confirmed: siRNA payloads were successfully delivered and active only by the targeted Nuvec particles compared to untargeted Nuvec, demonstrating that Nuvec can be directed to specific cell types; Broader validation of Nuvec: The findings strengthen the platform's potential as a differentiated delivery system for RNA therapeutics across multiple disease areas, including cancers of high unmet need such as lung and pancreatic cancers. challenges associated with the manufacturing and targeted delivery of RNA therapeutics are known to impact this market growth. Targeting RNA therapies to specific cells and tissues to maximise efficacy and reduce systemic toxicity is a holy grail for nucleic acid therapeutics developers and is challenging to achieve with established RNA delivery methods. In parallel to the successful targeting of Nuvec particles to cancer cells in collaboration with SRI, N4 Pharma has also demonstrated targeting of Nuvec to immune cells using mannose modification in its lead programme, N4 101, which is designed to be an orally delivered treatment for inflammatory bowel disease.

N4 Pharma plc Provides A Progress Update on the in Vitro Pre-Clinical Development of Its Lead Nuvec® Proof-Of-Concept Programme, N4 101 N4 Pharma Plc provided a progress update on the in vitro pre-clinical development of its lead Nuvec®? proof-of-concept programme, N4 101, an oral anti-inflammatory product for the treatment of Inflammatory Bowel Disease (IBD). The size of the global RNA therapeutics market was $13.7 billion in 2023 and is expected to reach $18.0 billion by 20281. challenges associated with the manufacturing and delivery of RNA therapeutics are known to impact this market growth - challenges which N4 Pharma is addressing with its Nuvec®? technology, aiming to become an industry leading delivery platform used by multiple pharmaceutical partners. N4 Pharma's oral IBD product, N4 101, is designed to showcase the key benefits of the Nuvec®? delivery technology where other approaches struggle: i) it can straightforwardly load multiple RNA therapeutics onto the same particle, ii) it protects the payload from enzyme degradation to allow oral delivery to the gut andiii) it can be functionalised to target specific cells. The Company has completed a series of in vitro experiments which clearly demonstrate these competitive advantages. Key Highlights: The efficiency of delivery and efficacy of an siRNA and an mRNA therapeutic used to treat IBD are demonstrably enhanced when delivered by targeted Nuvec®? particles compared with untargeted delivery; A Nuvec®? formulation dual loaded with both therapeutics at the same time shows equivalent efficacy to the separate treatments; A patent has been filed reflecting the clear advantages of Nuvec®? for targeting and dual loading; and, The Company is awaiting ethics committee approval to build on these excellent in vitro data and begin an in vivo study in an appropriate animal model early in 2025 at the University of Queensland.

New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 69% This is considered a major 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: Major Risks Less than 1 year of cash runway based on free cash flow trend (-UK£1.2m free cash flow).

N4 Pharma plc Provides A Further Successful Update on Its Ongoing Research Work into the Use of Nuvec to Enhance the Performance of Viral Vector N4 Pharma Plc provided a further successful update on its ongoing research work into the use of Nuvec®? to enhance the performance of viral vectors. Through its research programme with the University of Brunel, the Company has demonstrated via a series of in vitro experiments that Nuvec®? can deliver increased transduction efficacy, when complexed with Adeno-Associated virus 8 ("AAV8"). This follows on from earlier work where the Company showed that Nuvec®? increased transduction efficacy of a standard Adenovirus vector. Specifically, Nuvec®? was mixed with AAV8 carrying a fluorescent green protein gene and used to transduce human-like liver cells (induced pluripotent cell model). When the viral vector was complexed with Nuvec®?, transduction efficacy increased 2.5-fold compared to the AAV8 vector when used on a standalone basis. AAV8 was chosen for investigation as this virus is currently being used for products already in clinical development. Annonce • Dec 18
N4 Pharma Plc Provides Positive Update on its Ongoing Oral Delivery Research Work N4 Pharma Plc provided a positive update on its ongoing oral delivery research work. The Company through its research program with the University of Queensland is evaluating the potential of Nuvec to act as an oral delivery system for oligonucleotides including DNA and RNA. Experiments have now confirmed, in vivo, the successful oral administration of Nuvec loaded with a DNA plasmid for ovalbumin. The Nuvec was administered by enteric coated capsule and the contents, having been released in the intestinal lumen, were taken up by intestinal cells, with successful transfection and release of the newly synthesized ovalbumin. Specifically, the first experiment was a repeat of a study conducted earlier this year whereby an enterically coated capsule containing Nuvec loaded with an DNA plasmid for ovalbin was administered and protein expression was observed after 3 days. In this recent experiment, an additional second capsule was administered on day 3 which resulted in a much higher peak level of expression on days 4-7. Annonce • Dec 07
N4 Pharma plc Provides an Encouraging Update on Its Ongoing in Vitro Sirna Research Work N4 Pharma Plc provide an encouraging update on its ongoing in vitro siRNA research work. The Company's double loaded siRNA work is ongoing and the Board wishes to provide an update on the progress achieved so far, as reach the end of 2023. The work to date is very encouraging and is demonstrating that Nuvec® has considerable potential to be able to knockdown two independent pathways leading to more effective cancer treatments by reducing the ability for tumour escape. For the past few months, the Company has been investigating the ability of Nuvec® nanoparticles to be loaded with, and deliver at the same time, two different siRNA known to inhibit relevant oncology targets. This is cutting edge research in the use of nanoparticles as delivery systems in oncology and consequently the Company is proceeding carefully to ensure that it gains the maximum understanding of the cellular processes involved. Using multiple different siRNA constructs has demonstrated that two separate siRNA can be loaded onto Nuvec®without changing the size or charge of Nuvec®, both parameters being essential for successful cellular uptake. The initial work on cell growth involved investigating the combination of inhibition ofEGFR (epidermal growth factor receptor) andBCL-2:(B-cell lymphoma 2) using PC-9 cancer cells. As previously announced, each siRNA when separately loaded onto Nuvec® achieved cell inhibition and an assay to measure BCL-2 had been established. Subsequent work has confirmed that the expression level of BCL-2 in PC9 cells was at the limits of detection, and consequently unlike with EGFR, a knockdown response curve could not be measured. In view of the low BCL-2 expression, the Company has been investigating alternative cellular pathways that may be inhibited using siRNA loaded alongside EGFR. The first was BRD4 (Bromodomain-containing-protein 4)a target for which inhibitors are currently being evaluated in clinical trials in uveal melanoma, leukemia and carcinoma. The second target was PLK1 (Polo Like Kinase 1), inhibitors of which are in early clinical trials for lymphoma and pancreatic cancer. Additional targets may also be explored as the Company's work progresses. New Risk • Sep 13

N4 Pharma plc Provides Patent Filing Update N4 Pharma Plc provided an update on its patent application for Nuvec®, filed in March 2020 (no. PCT/GB2021/050960 Gene Therapy Vectors). The Company originally filed a Patent Cooperation Treaty patent application for Nuvec® to be used to manufacture viral vectors and to make viral vectors more efficient in applications such as ex-vivo gene therapy treatments. Under the terms of the PCT application process and following feedback from an international patent search, the Company is now making enhancements to the claims of the applications in the territories in which it wishes to gain patent protection. N4 pharma is pursuing this patent application which, if granted, would be in addition to the patents it has exclusively licensed from the University of Queensland. The Company has decided to focus its claims on the use of the specific spiky properties of Nuvec™ to load and transfect viral vectors, especially adenoviral vectors and lentiviral vectors. This is based on feedback from the examiner and further work the Company has done that has shown how combining Nuvec® with adenoviral vectors (in addition to its earlier work on lentiviral vectors) can lead to an improvement in vector performance and a reduction in the amount of the viral vector needed. The Company has filed ongoing patent applications in the following territories: Europe (including UK); USA; Japan; India and Canada. It will also file applications in Australia and China in due course. Annonce • Jul 15
N4 Pharma plc Provides Work Programme Update N4 Pharma Plc announced a further update on its recent pre-clinical study with TNF alpha. On 13 June 2022 the Company provided an update that the Medicines Discovery Catapult study showed clear tumor suppression with 10ug of the TNF-alpha loaded onto Nuvec which was a lower dose than used in the earlier studies. Biochemical analysis of blood and tissue samples has now been completed. Testing confirmed that treatment with10ugTNF-alpha loaded onto Nuvec resulted in an increase in circulating plasma TNF-alpha levels. Analysis also indicated that tissues including the liver and the tumor cells may have been responsible for the transfection with the TNF plasmid and subsequent release of TNF-alpha into the circulation to suppress the tumor. This study provides further data to better understand the mechanism that produced the tumor suppression. This data indicates the most appropriate use of Nuvec in the oncology field will likely be to combine it with one or more nucleic acids alongside a targeting ligand to allow specific cancer cells to be targeted.

N4 Pharma Plc Provides Details of Its Work Plan Following the Encouraging Data from Its Oncology Research N4 Pharma Plc provided details of its work plan following the encouraging data from its oncology research as announced on 13 December 2021. The Board announced that the studies conducted with Nanomerics to evaluate the potential of Nuvec® as a nano-carrier of a DNA plasmid expressing TNFalpha ("TNF"), a cytokine with immune-modulating properties against tumours, demonstrated a significant inhibition of tumour growth derived from a human cell line. As a result of these positive findings, the company has commenced work with Medicines Discovery Catapult ("Catapult") to extend the observations to allow it to identify suitable loads to add to Nuvec® to take to clinic. To date, the company has established that Nuvec® can deliver an appropriate biological load and this new study will help determine the mechanism of action that produced the tumor suppression. Amongst other things, it will seek to identify whether the Nuvec® loaded with TNF alpha was directly taken up by the tumour cells to produce the active TNF within the tumour or whether other organs such as the liver took up the Nuvec® and produced the TNF and released it systemically to suppress the tumour. If it can be demonstrated that Nuvec® can selectively deliver the plasmid to the tumour this may indicate the potential use of Nuvec® to deliver to tumours with a reduced systemic effect and inform the scope of any clinical studies or collaboration discussions. In addition, studies will use labelled Nuvec® particles to allow the organ and tissue distribution of Nuvec® to be followed. The company is also in the process of identifying alternatives to TNF as immunomodulators or gene therapy which may use Nuvec® as a delivery system. The selection process is expected to conclude shortly and the company intends to conduct a study programme similar to the work being undertaken using TNF. Annonce • May 21
N4 Pharma Plc Provides an Update on Collaboration Discussions and Its Ongoing in Vivo Work Programme N4 Pharma Plc provided an update on collaboration discussions and its ongoing in vivo work programme. In vivo studies: The company announced it has made good progress developing and testing a monodisperse formulation of Nuvec®. Previous updates have highlighted the success in preparing monodisperse formulations and recent results from a pilot in vivo study undertaken by Nanomerics have now indicated that a lower dose of 10ug pOVA bound to optimised, monodispersed Nuvec® gives a better result than a 50ug dose of the original, agglomerated Nuvec® used in previous in vivo studies. This recent study will be repeated and extended to validate the results seen from this pilot study which, if consistent, would demonstrate a significant improvement through the use of this newly formulated Nuvec® following 18 months of optimisation and formulation work. In light of the success with the pilot study, the Company is reviewing the scope of work at Evotec, which had been announced previously, to ensure that the different arms to the in vivo studies undertaken there are complementary and follow the approach undertaken in the Nanomerics pilot study. Whilst this work remains ongoing it is likely to push any results from the Evotec in vivo work into the third quarter of this year. Furthermore, with the work being undertaken under the MTA in respect of the proprietary plasmid DNA for Covid-19, the Company now intends to use this opportunity to assess whether Covid-19 plasmid DNAs other than the Covid-19 DNA plasmid licensed from the National Institute for Health may be more suited to its internal Covid-19 in vivo work. Indeed, depending on the results of the work done under the MTA and subsequent relationships, it may negate the need for the company to do its own proof of concept work with an 'off the shelf' Covid-19 plasmid.
