Co-development of NFL-301, a drug candidate to reduce alcohol consumption. New formulation developed and patent application filed
€3m fundraising round in January 2023 and up to €1.9m of non-dilutive financing secured in February 2023 (Bpifrance, France Relance 2030 stimulus plan)
Cash position: €3.6m as of September 30, 2023. Cash horizon secured through to the end of 2024.
NFL BIOSCIENCES (Euronext Growth Paris – FR0014003XT0 – ALNFL), a biopharmaceutical company developing botanical drugs for the treatment of addictions, is reporting its results for the first half of 2023, approved by the Board of Directors on October 5, 2023. On this occasion, NFL Biosciences looks back on its recent progress, including the promising results of the PRECESTO exploratory study, and confirms that the strategy for reporting the CESTO II results will make it possible to take into account the entire study, which will remain double blind through to 12 months of monitoring, with the results of this Phase 2b study expected in July 2024.
October 12, 2023 at 2:30 pm CET - Webinar for shareholders and investors NFL Biosciences will discuss the promising results of the Phase 2a PRECESTO exploratory study, which demonstrated a clinically relevant effect of NFL-101 on the reduction of satisfaction with cigarettes, and the development strategy of CESTO II, its Phase 2b clinical study to evaluate the efficacy of NFL-101, currently underway on 318 smokers in 8 clinical investigation centers. NFL Biosciences executives will also discuss the development of NFL-301, a drug candidate to reduce alcohol consumption. >> Click here to register1 .
PRECESTO is the second study after CESTO which highlights the effect of NFL-101 in terms of reducing smoking satisfaction. The clinically relevant effect is also more prolonged than expected.
These results confirm the therapeutic interest of NFL-101 administered on its own or in combination with nicotine replacement therapies, which reduce withdrawal symptoms. They corroborate the results of the patent application filed in the United States in October 2022, increasing the probability of a patent being issued that would offer protection through to 2042 as a minimum.
A detailed presentation of the results is appended.
CESTO II is a multicentric, randomized, double blind and placebo-controlled phase 2b clinical trial. The trial is being conducted as follows:

• The subjects receive two initial subcutaneous injections one week apart. Additional follow-up injections could be provided after three and six months for subjects who have not stopped smoking by these dates.
This study's primary objectives are to select the best dose and assess the efficacy of NFL-101 versus placebo. The main criterion is continued abstinence for four weeks and the key secondary criterion is continued abstinence for six months, measured from 15 days after the first administration and confirmed by measuring exhaled CO. Other secondary criteria are also being studied, including continued abstinence for three months, nine months and 12 months, continued abstinence at the end of the treatment for three months and six months, and continued abstinence during the last three months of the study. A number of exploratory criteria will then be analyzed.
The recruitment of subjects started in January 2022, gradually mobilizing a total of eight Clinical Investigation Centers (CIC) at CHU university hospital centers (Bordeaux, Clermont-Ferrand, Dijon, Lorient, Marseille, Montpellier, Poitiers and Rennes), as well as the Eurofins-Optimed research institute (Grenoble). The final and 318th randomization was carried out at the start of May 2023.
An analysis of the results had been announced after reaching six months of monitoring for the 318th subject. Under this reporting strategy, the analysis of continued abstinence rates based on the data for the first six months monitored involved unblinding the study. This limited the opportunities to capitalize on the data collected between the 6th and 12th months, which would be considered as open data. Maintaining the blind during the planned 12 months of monitoring would make it possible to maximize the use of all the data collected during the CESTO II study.
The observation of a more prolonged effect than expected during the PRECESTO study calls for a certain level of caution concerning an early review of the results leading to an unblinding before the end of the planned 12 month monitoring period. If an immune response is triggered by the administration of NFL-101, this could, in addition to an immediate effect that would support the success of an attempt to stop smoking, result in a longerterm effect in terms of preventing or managing relapses.
The CESTO II study includes a hierarchy within the criteria for analysis: there is one primary criterion, then one key secondary criterion, six secondary criteria and a number of exploratory criteria. Each of the secondary criteria has a high level of clinical relevance. Maintaining the blind during the 12 months of monitoring will then make it possible to fully capitalize on the results obtained concerning these secondary criteria.
For these three reasons, and because the CESTO II study has been the focus of the majority of the Company's resources for a total of around €8m, the decision has been taken to maximize the use of the data generated. This involves maintaining the blind through to the end of the planned observation period.
The provisional schedule is as follows:
It is important to remember that the Company continues to be subject to the blind condition, in the same way as the subjects, the clinical centers and the Eurofins Optimed CRO.
In February 2023, NFL Biosciences set up a research partnership with the French Alternative Energies and Atomic Energy Commission (CEA) to study the mechanism of action of its drug candidate NFL-101.
This study is being led by the CEA's Paris-Saclay Pharmacological Neuroimaging team. It will focus on following, by positron emission tomography (PET) imaging, the modifications in the cerebral function associated with the development of tobacco addiction in mice, in order to highlight the central effects of NFL-101 treatment.
The results are expected before the end of the first quarter of 2024.
Under the co-development agreement set up at the start of 2022, NFL Biosciences and its industrial partner Athena Pharmaceutiques have developed a prolonged-release form of kudzu plant extracts in microgranule form, NFL-301. NFL Biosciences aims to develop the first oral delivery drug based on kudzu extracts to tackle excessive alcohol consumption.
NFL is preparing a pre-IND in the United States, which is expected to be submitted before the end of the fourth quarter of 2023, with a view to obtaining FDA approval for the manufacturing process, product quality and development strategy through to the MA.
There are no plans for any significant spending on the development of NFL-301 over the next nine months. The current work primarily concerns regulatory and consultation aspects.
NFL Biosciences has continued moving forward with its intellectual property protection strategy for NFL-101 and NFL-301.
Patent application for NFL-301: a patent application has been filed in the United States for the formulation of NFL-301 with a commitment to extending this globally. This first patent application for NFL-301 aims to protect prolonged-release formulations of extracts of kudzu, a plant used in traditional Chinese medicine, as well as their uses for the treatment of alcohol consumption reduction.
Patent approval on NFL-101: NFL Biosciences has three patent families granting it extensive international protection for its drug candidate NFL-101, including Europe, the United States, China and Japan.
Looking beyond the studies underway (CESTO-II and the collaboration with CEA-Saclay), NFL BIOSCIENCES will focus on continuing to develop NFL-101 in partnership with pharmaceutical companies that are interested in the addiction field. As part of its normal business operations, the Company has already had discussions with several international pharmaceutical companies. Considering the positive results seen with PRECESTO, these discussions could be ramped up.
Regarding the partnership with THEMIS PHARMACEUTICALS in India, the development strategy in this country is also being reassessed following the results of the PRECESTO clinical trial.
NFL Biosciences has been invited to attend two major business conferences over the coming months, where its discussions with pharmaceutical companies and institutional investors will continue:
At the start of 2023, NFL Biosciences successfully rolled out its financing strategy by applying for various grants and advances, and calling on the financial markets. In total, €4.2m were received during the first quarter of 2023 and €0.7m are still to be received as findings are generated confirming the success of the trials, representing a total secured amount of €4.9m (€3m through a capital increase and €1.9m of repayable advances or grants). This has enabled NFL Biosciences to secure financing to drive progress with its priority projects, and it has a cash horizon that now runs through to the fourth quarter of 2024.
NFL Biosciences will continue to benefit from an organization with limited fixed costs. Looking further ahead, NFL Biosciences will need additional financing which, independently or combined, may come from (1) capital increases, (2) non-dilutive financing and (3) partnerships with pharmaceutical companies.
On February 27, 2023, the Board of Directors appointed Dr Ignacio Faus, the Company's Chief Executive Officer, as Chairman of the Board of Directors for a period that will not exceed his term of office as a director, i.e. through to the end of the Ordinary General Shareholders' Meeting held in 2024 to approve the financial statements for the year ending December 31, 2023.
On June 27, 2023, the shareholders approved the appointment of Ms Dominique Côté as an independent director. Her three-year term of office will expire at the end of the Ordinary General Shareholders' Meeting held in 2026 to approve the financial statements for the year ending December 31, 2025.

During the first half of 2023, NFL Biosciences recorded €94K of operating income. This amount corresponds to part of the operating grant awarded by Bpifrance (total amount of €200K). Still in the clinical trials development stage, NFL Biosciences did not record any revenues during the last two years.
In line with the resources allocated to drive progress with the programs presented above, and the Company's operations, EBIT came to €(2.4)m for the first half of 2023, compared with €(1.3)m for the same period in 2022. Payroll and social security contributions totaled €307K for four people at June 30, 2023, compared with €254K for three people at June 30, 2022.
During the first half of 2023, NFL Biosciences recorded a research tax credit (CIR) of €203K, compared with €101K for the first half of 2022, with this change reflecting the ramping up of its research programs. Over the period, NFL Biosciences received €161K of prefinancing from the research tax credit reported in 2022, which totaled €397K.
Financial income and expenses for the first half of 2023, which came to €71K, compared with €108K one year earlier, take into account the remuneration from investments of cash surpluses for €32K and the reversal of depreciation concerning the liquidity agreement for €39K. As a result, NFL Biosciences recorded €(2.1)m of net income over the period, compared with €(1.1)m at June 30, 2022.
At June 30, 2023, the Company had €1.9m of shareholders' equity and €3.4m of available cash. Cash and cash equivalents reflect the capital increase carried out at the end of January 2023 (€3.0m), as well as the advances granted by Bpifrance for the NFL-101 and NFL-301 clinical trials (€1.1m).
In the third quarter of 2023, the Company received €550K of proceeds from the exercising of the BSA and BSPCE warrants from end-June and July 2023 for a total of €550K, as well as the first installment of the grant for the PRECESTO study for €140K.
Dr Ignacio Faus, NFL Biosciences Chairman of the Board and CEO: "We are very satisfied with the progress made in the past few months. We carried out the PRECESTO Phase 2a clinical trial while respecting the budget and timeframes that were set. The results achieved with PRECESTO, which are presented in detail in this press release, are very promising. PRECESTO is the first placebo-controlled clinical trial for NFL-101. We have shown that NFL-101 has a greater effect than placebo on reducing smoking satisfaction. For CESTO II, we also aim to complete this clinical trial on budget and on time. After reviewing the PRECESTO results, the Board of Directors decided to modify the schedule for reporting the CESTO-II results with a view to maximizing the study's potential.
With regard to NFL-301, our product for reducing alcohol consumption, we have made progress with developing a new product formulation. Over the next nine months our development will continue moving forward.
As we have already mentioned, NFL Biosciences has a very robust approach in place for managing fixed costs. We use the funds that are allocated to us with the greatest care and we focus them primarily on funding scientific studies. Thanks to this, the Company's cash horizon can be extended through to the end of 2024.
Given the small size of the company, we will prioritize partnerships for the development of NFL-101 beyond the studies that are underway. Discussions have been started with major American and European pharmaceutical companies and, considering the positive results achieved with PRECESTO, they could now be accelerated".

NFL Biosciences is a biopharmaceutical company based in the Montpellier area which develops botanical drug candidates for the treatment of addictions. NFL Biosciences' ambition is to bring new, natural, safer and more effective therapeutic solutions to the entire world population, including low- and middle-income countries. Its most advanced product, called NFL-101, is a standardized, nicotine free tobacco leaf extract protected by two patent families. NFL Biosciences intends to offer smokers who want to quit a natural, safe, easy-to-administer and personalized alternative. NFL Biosciences is also developing NFL-301, a natural drug candidate for the reduction of alcohol consumption and has a drug development project for the treatment of cannabis use disorder.
PRECESTO is a monocentric, placebo-controlled, randomized and double-blind Phase 2a exploratory study, with a crossover covering two periods of 28 days each, including 34 smokers who do not want to quit and have high smoking satisfaction. Each participant is his or her own control and receives, on a random and alternating basis, either NFL-101 or the placebo at the start of each of the two periods. At the end of the study, all the participants received one dose of NFL-101 and one dose of the placebo. For each participant, the order in which NFL-101 and the placebo were administered was kept secret. For each period, the participants received the treatments on day 1 (D1) then answered, with complete independence, the modified Cigarette Evaluation Questionnaire (mCEQ) on days 4 (D4), 7 (D7), 14 (D14), 21 (D21) and 28 (D28).
The objective of PRECESTO, as mentioned in the protocol, is to "assess the efficacy of NFL-101 to reduce the positive reinforcement of cigarettes as measured by the subscale assessing smoking satisfaction (questions 1, 2 and 12) from the mCEQ versus a placebo". The primary criterion resulting from this objective was chosen as "the Smoking Satisfaction subscale (items 1, 2 and 12) from the mCEQ measured on D4".
The mCEQ is an international questionnaire that is completed independently. The study's participants, smokers who have high smoking satisfaction and do not wish to quit, answer 12 questions marking the number that best represents how smoking makes them feel (1-not at all, 2-very little, 3-a little, 4-moderately, 5-a lot, 6-quite a lot, 7-extremely). The questions are as follows:
The questionnaire uses three multi-item subscales and two single items: ""Smoking Satisfaction" (items 1, 2, and 12); "Psychological Reward" (items 4 through 8); "Aversion" (items 9 and 10); "Enjoyment of Respiratory Tract Sensations" (item 3); and "Craving Reduction" (item 11). Scores for each subscale are calculated as the mean of the individual item responses or the single item. Each score may therefore vary from 1 to 7. Higher scores indicate greater intensity on that scale.
The participants in the PRECESTO study completed this questionnaire themselves remotely using their computer. They were asked to refer to the cigarette that they smoked the previous day after dinner in order to standardize, insofar as possible, the change in perceptions over time for each subject.
The PRECESTO study makes it possible to better understand the activity of NFL-101 and specifically this product's efficacy in terms of reducing smoking satisfaction.
In the fight against smoking, reducing smoking satisfaction is essential: to successfully stop smoking, it is vital to tackle both smoking satisfaction and nicotine withdrawal. In terms of withdrawal, there are nicotine replacement therapies, but to tackle satisfaction, there are no effective medicinal products that do not have side effects.
The study is important in relation to NFL BIOSCIENCES' development plan for three reasons:
It was previously verified that the statistical analysis could be carried out on all subjects and for the 2 sequences jointly. The data are processed by calculating the least squares mean taking into account the study's crossover design and in accordance with the PRECESTO protocol.
Smoking satisfaction is the average for the answers to questions 1, 2 and 12 from the questionnaire. On inclusion, the average score for smoking satisfaction was 6.12 (standard deviation 0.77).
Figure 1 – Reduction in smoking satisfaction with NFL-101 and the placebo
Figure 2: Difference between the reduction in smoking satisfaction with NFL-101 and the placebo, including the exploratory p-values
For the p-values of 0.0003 and 0.007, this means that if there were no real effects or differences in the data, there would be just a 0.03% and 0.7% chance of obtaining data that were as different as those observed.
The calculation of the exploratory p-values carried out with a post hoc analysis was limited to the study's primary objective. This approach makes it possible to reduce the risks of obtaining low p-values resulting from chance, which may be the case when p-values are calculated on a number of criteria or even by crossreferencing the criteria in relation to one another. These calculations make it possible to adapt to the observation of a more prolonged effect than expected, while respecting the spirit of the protocol and its primary objective.
With the PRECESTO study, the mCEQ was completed by smokers who did not want to quit and who smoked ad libitum ("as often as desired"). It is recognized that reducing the consumption of cigarettes or stopping smoking generates significant effects on the perceptions and the behavioral responses associated with cigarette consumption. The crossover design did not make it possible to include subjects who were going to reduce their consumption or make attempts to stop as this would have resulted in a too significant carry-over effect (persistence or continuation of an effect) from period 1 to period 2. In addition, recruiting subjects who wanted to stop smoking would have involved the risk of information loss if they stopped, because subjects who stop smoking can no longer assess their level of smoking satisfaction and therefore complete the questionnaire. By recruiting smokers who do not want to stop smoking, it was more difficult to show an effect for NFL-101 on certain criteria such as craving as this was regularly reduced by the cigarettes smoked without any constraints.

| Monitoring timeframe | 2 periods of 28 days | 12 months |
The two clinical trials are very different.
It is also important to note that there is no clinical data available from previous research making it possible to calculate a level of efficacy for smoking cessation based on continued abstinence through a reduction in smoking satisfaction.
This exploratory study:
• corroborates the clinical results already mentioned in the patent application filed in the United States in October 2022 and further strengthens the solidity of the patent application and the probability of a patent being issued, which would result in protection through to 2042 as a minimum.
