"Completing the enrollment of the recommended phase 2 dose patient expansion cohort is an important milestone as the data from this trial guides further development plans and associated discussions with the Food and Drug Administration (FDA)," said Daniel Passeri, chief executive officer of Cue Biopharma. "We believe the updated data will build upon the already promising clinical profile established to date, which has shown an enhancement of clinical efficacy with the CUE-101-pembrolizumab combination compared to pembrolizumab alone. With the strength of the data already observed with monotherapy in second line patients and beyond, combined with the promising combination data emerging in 1L with pembrolizumab, we plan to discuss potential registrational paths with the Food and Drug Administration (FDA) for CUE-101 both as a monotherapy and in combination with pembrolizumab, leveraging the Fast Track Designation previously granted to these programs."

Matteo Levisetti, M.D., chief medical officer of Cue Biopharma added, "We believe the data from our CUE-101 trial represents a potential therapeutic breakthrough for HPV+ R/M HNSCC patients, bolstering our confidence in the platform to address unmet needs of patients suffering from a myriad of cancers. The maturing clinical data for CUE-101 further supports the mechanism of action which enables selective expansion of targeted tumor-specific T cells and also provides clinical validation and de-risking of our Immuno-STAT platform. This clinical validation is also being supported by a Phase 1 trial with our second CUE-100 series biologic, CUE-102, for Wilms’ Tumor 1-expressing tumors. Data to date has demonstrated clinical evidence of anti-tumor activity across multiple indications in patients treated in the dose escalation portion of the study, and we look forward to presenting the data at SITC (Free SITC Whitepaper)."

About the CUE-100 Series
The CUE-100 series consists of Fc-fusion biologics that incorporate peptide-MHC (pMHC) molecules along with rationally engineered IL-2 molecules. This singular biologic is anticipated to selectively target, activate and expand a robust repertoire of tumor-specific T cells directly in the patient’s body. The binding affinity of IL-2 for its receptor has been deliberately attenuated to achieve preferential selective activation of tumor-specific effector T cells while reducing the potential for effects on regulatory T cells (Tregs) or broad systemic activation, potentially mitigating the dose-limiting toxicities associated with current IL-2-based therapies.

DEP® irinotecan combination data to be presented at international oncology conference

On September 26, 2023 Starpharma (ASX: SPL, OTCQX: SPHRY) reported the presentation of data that demonstrate the benefits of combining DEP irinotecan with other important classes of anti-cancer therapies, including immuno-oncology (IO) agents, in models of human colorectal cancer (Press release, Starpharma, SEP 26, 2023, View Source;mc_eid=bf52dd3418 [SID1234635420]). The data will be presented in Boston, US, at the AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper), co-hosted by the American Association For Cancer Research (AACR) (Free AACR Whitepaper), the National Cancer Institute (NCI) and the European Organisation for Research and Treatment of Cancer (EORTC) from 11 to 15 October 2023. This poster presentation is one of three by Starpharma at the AACR (Free AACR Whitepaper)-NTI-EORTC conference showcasing multiple DEP programs, including DEP irinotecan and Starpharma’s radiotheranostic, DEP HER2-zirconium.

This DEP irinotecan combination poster builds on Starpharma’s recently released positive clinical data on DEP irinotecan in advanced colorectal cancer (CRC) and advanced platinum-resistant ovarian cancer2.

The DEP irinotecan combination data to be presented show DEP irinotecan improves the anti-tumour activity of an IO agent3 in the same class as the highly successful Merck product, Keytruda (pembrolizumab), including in models of CRC that respond poorly to IO agents.

DEP irinotecan in combination with the IO agent enhanced anti-tumour responses compared to the IO agent alone in a CRC model that is only moderately responsive to the IO agent. The combination also resulted in complete tumour regression and prolonged survival compared to the IO agent alone in this CRC model. In another model of CRC that was not responsive to the IO agent alone, the anti-tumour effects of the combination of DEP irinotecan and the IO agent were enhanced when compared with either agent alone.

DEP irinotecan’s ability to elicit an anti-cancer response to an IO agent in an otherwise non-responsive CRC tumour is significant. These improved results in CRC models provide a rationale for a potentially important new application of DEP irinotecan in combination with IO agents, which are a leading and growing class of anticancer therapies.

Importantly, 85% to 95% of CRC patients do not respond to IO agents, such as Keytruda, and this cancer remains a significant unmet medical need. These CRC patients do not respond to IO agents because their cancer is classified as microsatellite stable (MSS). These MSS cancers are more difficult to treat, more likely to recur, and typically less responsive to IO therapies than cancers that are not MSS. This DEP irinotecan poster includes new clinical data from Starpharma’s Phase 1/2 trial of the product showing that all CRC patients who responded to DEP irinotecan were MSS and, therefore, in the category that is more difficult to treat.

IO agents have changed the landscape of cancer treatment, demonstrating impressive results in treating a number of cancers, including lung cancer and melanoma, and generating over USD $60.3 billion in sales in 2021, with sales predicted to grow 14 to 17% per year to 20264.

IO anti-cancer drugs are designed to disrupt normal immune processes, allowing the body’s immune cells to effectively target and destroy cancer cells. Currently marketed IO drugs include Keytruda (Merck), Opdivo (BMS), Yervoy (BMS), Tecentriq (Genentech), and Imfinzi (AstraZeneca). The global colorectal cancer drugs market was valued at ~US$14 billion in 2023 and is forecast to reach more than US$16 billion by 20275. Immunotherapies, such as Keytruda, had approximately 25% market share in 20186.

Despite their impressive efficacy, IO agents can cause serious immune-mediated adverse events that are challenging to manage. Treatment with DEP irinotecan resulted in no immune-mediated adverse events in CRC and ovarian patients, and therefore, there was no overlap of adverse events with those reported for IO agents – another benefit for this combination application.

In addition to the promising data for DEP irinotecan in combination with the IO agent, Starpharma’s poster also includes data on DEP irinotecan in combination with AstraZeneca’s Lynparza (olaparib). Olaparib is from a class of drugs called PARP inhibitors. DEP irinotecan also showed a synergistic effect in combination with olaparib in a model of CRC. The CRC model used was resistant to olaparib alone, but the combination of DEP irinotecan and olaparib achieved increased anti-tumour effects compared to DEP irinotecan alone, and also prolonged survival.

Lynparza had global sales of more than US$2.6 billion in 20227 and is approved for use in ovarian, breast, pancreatic and prostate cancers.

The data showing DEP irinotecan enhances anti-tumour responses of the IO agent and PARP inhibitor in models of cancer, together with the promising clinical efficacy and safety profile of DEP irinotecan in CRC and ovarian cancer, provide a strong rationale for clinical evaluation of DEP irinotecan in combination with IO agents and PARP inhibitors. These combination regimens are commercially important because they increase the potential market opportunities for DEP irinotecan and illustrate synergies with successful product categories. Given these findings, Starpharma is engaging in discussions with potential commercial partners, including companies that currently market IO agents.

The above-mentioned poster is one of three posters Starpharma is presenting at the AACR (Free AACR Whitepaper)-NCI-EORTC conference in October 2023.

Thursday, 12 October (Poster Session A): A147: A HER2 targeted polylysine dendrimer nanoparticle radiotheranostic demonstrates excellent tumor accumulation, rapid clearance from circulation, and promising performance in PET-CT imaging.
Friday, 13 October (Poster Session B): B039: A phase 1/2 study of dendrimer-enhanced (DEP) SN38 (SN38-SPL9111 / DEP irinotecan) in patients with advanced solid tumours.
Saturday, 14 October (Poster Session C): C167: An SN38 dendrimer nanoparticle, DEP irinotecan (SN38-SPL9111), demonstrates efficacy in mouse models of gastrointestinal cancer and augments anti-tumor effects of immune checkpoint blockade and PARP inhibition.
Abstracts, which include a summary of the data, will be published on the conference website ahead of the conference, and the full posters will be made available by Starpharma following publication.

About DEP irinotecan

DEP irinotecan is a novel, patented, nanoparticle formulation of SN38, the active metabolite of the widely used anti-cancer drug, irinotecan (marketed as Camptosar), delivered using Starpharma’s proprietary DEP technology. Camptosar and all generic forms of conventional irinotecan carry ‘black box’ warnings mandated by the US Food and Drug Administration (FDA) for both neutropenia and severe diarrhoea, which can be dose-limiting and life-threatening. DEP irinotecan has not resulted in severe diarrhoea in Phase 2 studies. DEP irinotecan has patent filings to 2039 and up to an additional five years.

The severe diarrhoea caused by conventional irinotecan results from the production of toxic metabolites during the liver metabolism of irinotecan to SN38. DEP irinotecan was designed to eliminate the need for liver metabolism, thereby avoiding the production of toxic metabolites.

About Starpharma’s DEP irinotecan Phase 2 clinical trial

Starpharma is evaluating DEP irinotecan as both a monotherapy and in combination with 5-fluorouracil (5-FU) and leucovorin (LV), which is a standard irinotecan combination regimen used in the treatment of CRC known as "FOLFIRI". The Phase 2 DEP irinotecan trial is being conducted at multiple sites, including Guy’s Hospital in London, Beatson Cancer Centre in Glasgow, Imperial College London, and the Kinghorn Cancer Centre in Sydney.

Clinical and commercial opportunity for DEP irinotecan

The global colorectal cancer drugs market was valued at ~US$14 billion in 2023 and is forecast to reach more than US$16 billion by 20278.

Camptosar and generic forms of conventional irinotecan are standard-of-care treatments for advanced CRC, with Pfizer’s Camptosar achieving peak sales of ~US$1.1 billion. CRC accounts for approximately 10% of all new cancer diagnoses and is the second leading cause of cancer, affecting more than 1 million people annually, and is the fourth leading cause of cancer-related death.

CRC incidence is increasing markedly among younger age groups, with rates of colon cancer more than doubling in adults aged 20 to 54 since the 1990s. Studies have shown that, compared with adults born around 1950, those born around 1990 have double the risk of colon cancer and quadruple the risk of rectal cancer.

Vaccinex Reports Groundbreaking Findings at Medical Conferences Supporting Development of Pepinemab for the Treatment of Neurodegenerative Diseases and Cancer

On September 26, 2023 Vaccinex, Inc. (Nasdaq: VCNX), a clinical-stage biotechnology company will report on novel findings for its lead product, pepinemab, with implications for treatment of Alzheimer’s and other slowly progressive neurodegenerative diseases and for cancer immunotherapy at two upcoming Medical Conferences (Press release, Vaccinex, SEP 26, 2023, View Source [SID1234635418]).

Results from our phase 2 SIGNAL trial suggest pepinemab is the first therapeutic agent that appears to have the potential to prevent decline in brain metabolic activity and to slow or halt cognitive decline in Huntington’s disease (HD) [1], a slowly progressive, orphan neurodegenerative disease with many pathological similarities to the much more prevalent Alzheimer’s disease (AD). Encouraged by these findings, a separate, randomized, phase 1/2a study in AD is ongoing in which the last patient is anticipated to complete the planned 12-months of treatment in early June 2024.
Pepinemab in combination with a checkpoint inhibitor is, to our knowledge, the first treatment that has shown the potential to induce formation of lymphoid structures in tumors that promote efficient immune responses and are known to be associated with improved outcomes in head and neck cancer. Clinical results indicate an approximate doubling of objective responses (ORR) and progression free survival (PFS) relative to historical results with checkpoint monotherapy in patients with hard-to-treat tumors that express low levels of PD-L1 (CPS<20) (described in detail below).
Alzheimer’s Disease

Vaccinex completed enrollment in the randomized, double-blind SIGNAL-AD phase 1/2a study (NCT04381468) for early AD in May 2023. The last patient is anticipated to complete the planned 12 months of treatment by early June 2024 at which time the database will be locked and results analyzed. Key endpoints include brain metabolic activity (FDG-PET, a biomarker of disease progression) along with measures of cognition specific to AD (CDR-SB, ADAS-Cog13) that have been recognized as clinically meaningful by the U.S. Food and Drug Administration (FDA). Investors will be aware of recent excitement surrounding full FDA approval of Eisai and Biogen’s drug Leqembi (lecanemab), the first anti-Aβ amyloid antibody for treatment of AD. A second such drug from Eli Lilly, donanemab, has reported equivalent data and may be FDA approved before year end. Clinical consensus is that Leqembi and donanemab provide a modest but real benefit to patients at a very early stage of disease. Common side effects associated with these drugs, however, include an inflammatory and hemorrhagic response in brain denoted as ARIA. Although ARIA often resolves itself, it has proven to be life-threatening in a small percentage of patients. As a result, all patients treated with these drugs must be followed carefully with significant effort and expense to avoid complications. It is important to appreciate that pepinemab has a very different mechanism of action than Leqembi or donanemab and, in clinical studies conducted to date, has not been found to be associated with inflammatory responses in the brain.

We believe that use of pepinemab to treat slowly progressive neurodegenerative diseases like AD has been substantially de-risked by results from our completed phase 2 study in HD. We have had the opportunity to meet with several major pharmaceutical companies. We believe from their responses that they have prioritized improving treatments for AD ("Our team was really intrigued by the data you presented and would like to continue our dialogue. However, we see your upcoming AD data as being essential to confirm the signal obtained in HD, and we would therefore gladly re-engage then."; "…we are enthused by the mechanism of Sema4D. We would be interested in re-engaging once your on-going Phase 2 [AD] is available."; "Let’s meet again when you are able to discuss the AD data with pepinemab.")

We believe that the prevalence of AD (6 million people diagnosed with AD in the US alone) and current concerns about the limitations of anti-Aβ amyloid antibodies would make pepinemab attractive as a potential alternative to anti-Aβ antibodies or possibly for use in combination with an anti-Aβ for greater efficacy. The potential impact of the AD program on Vaccinex valuation and financial resources, therefore, make this Vaccinex’s most important near term catalyst. Our highest priority in the coming months will be to complete the SIGNAL-AD trial, which we believe may make substantial resources available for our initiatives in cancer and other neurodegenerative diseases such as HD.

Cancer

The Phase 2 KEYNOTE-B84 study (NCT04815720) evaluated Vaccinex’s pepinemab antibody in combination with Merck’s anti-PD-1 therapy, KEYTRUDA (pembrolizumab) for immunotherapy of recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). Results of a preplanned interim analysis of the first 36 patients treated in this study indicated that the Objective Response (ORR) for the PD-L1 low population, CPS <20 (N=19), was 21.1% (2 CR and 2 PR) and median progression free survival (PFS) was 5.79 months, which are approximately twice that of historical ORR and PFS for checkpoint monotherapy in this population [2]. In contrast, in the CPS ≥20 (N=17) subgroup, the ORR and PFS for combination therapy was similar to historical checkpoint monotherapy. The improvement in response to treatment is important for the 55% of HNSCC patients whose tumors are characterized as CPS <20. These data are also consistent with a prior study in which we observed that the combination of pepinemab with PD-L1 inhibitor BAVENCIO (avelumab) appeared to approximately double ORR in patients with PD-L1-low non-small cell lung cancer (NCT03268057) [3].

In view of these clinical findings, we investigated the changes in the tumor immune environment that might correlate with response to pepinemab treatment by analyzing pre-treatment and on-treatment tumor biopsies collected during the KEYNOTE-B84 study. The results indicate that treatment with pepinemab in combination with KEYTRUDA appears to induce formation of highly organized lymphoid aggregates in the tumor of patients who demonstrate disease control (complete response plus partial response plus stable disease). Such aggregates are characterized by a high density of B cells, antigen-presenting dendritic cells and activated T cells (Figure 1A); further, treatment-induced increase in the number of aggregates correlates with Disease Control (Figure 1B) and with Progression Free Survival.

Representative images of 5-week on-treatment biopsies. Left: from a patient with stable disease, tumor biopsy contains highly organized immune aggregates consisting of high density antigen presenting cells (B cells, DC dendritic cells) as well as T lymphocytes. Right: from a patient with progressive disease, immune cells in the tumor biopsy are disorganized and include relatively high levels of inhibitory T regulatory (Treg) cells, but relatively few antigen presenting cells (B cells, DC).
Patients who experience clinical benefit (Disease Control) during treatment with pepinemab and KEYTRUDA have a higher frequency of mature immune aggregates with a high density of B cells in their on-treatment biopsy compared to their pre-treatment biopsies, p<0.0001. This difference is not observed in on- and pre-treatment biopsies from patients whose cancer progresses rapidly. One-way ANOVA, **** p<0.0001; ns = not significant, p≥0.05.
Immune Aggregates correlate with PFS. On-treatment patient biopsies with B cell aggregates positively correlate with longer progression-free survival. Log Rank survival analysis, p= 0.0056.
We and our collaborators at the Winship Cancer Center of Emory University have reported similar observations indicating that combination immunotherapy with pepinemab induces mature lymphoid structures in tumors of patients with metastatic melanoma treated in the neoadjuvant setting (NCT03690986) [4].

Based on these findings, we and our pharmaceutical collaborator, Merck Sharp & Dohme LLC, a subsidiary of Merck and Co., Inc., Rahway, NJ, USA, are in the preliminary testing and design stages of a potential extension of this study that may focus on treatment with pepinemab and KEYTRUDA in combination with chemotherapy. In previous studies of checkpoint monotherapy, addition of chemotherapy has been observed to approximately double the frequency of ORR. We believe that a similar effect is likely for addition of chemotherapy to treatment with pepinemab in combination with KEYTRUDA. We hope to subsequently determine whether, in the setting of more mature lymphoid structures in tumors, such treatment also prolongs overall survival.

Vaccinex has global commercial and development rights to pepinemab and is the sponsor of the KEYNOTE-B84 study which is being performed in collaboration with Merck Sharp & Dohme LLC, a subsidiary of Merck and Co., Inc., Rahway, NJ, USA. Additional information about the study is available at: clinicaltrials.gov.

Revenue

For the three- and nine-month periods ended August 31, 2023, consolidated revenue was $20,855,000 and $58,312,000, compared to $20,811,000 and $58,636,000 for the same periods ended August 31, 2022, representing a year-over-year increase of 0.2% for the third quarter and a decrease of 0.1% for the first nine months of the fiscal year.

For the third quarter of fiscal 2023, net sales of EGRIFTA SV were $13,183,000 compared to $12,876,000 in the third quarter of fiscal 2022, representing an increase of 2.4% year-over-year. Higher sales of EGRIFTA SV in the quarter were mostly the result of a higher selling price but were hampered by slightly higher rebates to government payers. Net sales for the nine-month period ended August 31, 2023, which amounted to $36,747,000 compared to $35,966,000 in the same period in 2022, representing growth of 2.1%, were mostly affected by the higher inventory drawdowns at the specialty pharmacy level in the second quarter of 2023, as explained in our second quarter financial disclosure.

Trogarzo net sales in the third quarter of fiscal 2023 amounted to $7,672,000 compared to $7,935,000 for the same quarter of 2022, representing a decrease of 3.3% year-over-year. Lower sales of Trogarzo were a result of our decision to stop commercializing the product in the European territory, where we recorded sales of $517,000 in the third quarter of 2022, as well as slightly lower unit sales in North America, which were offset by a higher selling price.

For the nine-month period ended August 31, 2023, Trogarzo net sales were $21,565,000 compared to $22,640,000 in the same period in 2022. North American net sales of Trogarzo were essentially flat when excluding European net sales of $1,028,000 for the nine-month period ended August 31, 2022.

Cost of Sales

For the three- and nine-month periods ended August 31, 2023, cost of sales decreased to $4,967,000 and $14,569,000 compared to $5,292,000 and $20,370,000 for the same periods in fiscal 2022.

Cost of goods sold was $4,967,000 and $14,569 ,000 in the three- and nine-month periods of 2023 compared to $5,292,000 and $17,929,000 for the same periods in 2022. The decrease in cost of goods sold was mainly due to a higher proportion of EGRIFTA SV sales, which carry a lower cost of goods sold than Trogarzo. For the first nine months of 2023, lower cost of goods sold is mainly the result of a charge of $1,788,000, in 2022, arising from the non-production of scheduled batches of EGRIFTA SV that were cancelled due to the planned transition to the F8 Formulation. No such charge was recorded in 2023. The higher proportion of net sales of EGRIFTA SV also had a positive impact on cost of goods sold in 2023, compared to 2022.

Cost of sales also included the amortization of the other asset of $2,441,000 for the nine-month period ended August 31, 2022. As the other asset was fully amortized during fiscal 2022, amortization of the other asset in fiscal 2023 is nil.

R&D Expenses

R&D expenses in the three- and nine-month periods ended August 31, 2023, amounted to $5,396,000 and $25,141,000 compared to $8,425,000 and $27,484,000 in the comparable periods of fiscal 2022.

R&D expenses decreased by 36.0% in the third quarter of 2023 compared to the same period last year, mostly due to the lower spending on our oncology program, lower spending in Europe, as well as lower spending following the near-completion of our lifecycle management projects for EGRIFTA SV and Trogarzo. For the first nine months of 2023, R&D spending decreased by 8.5%, again mostly due to lower spending on our various programs. R&D expenses in the first and second quarters of 2023 were also negatively impacted by expenses of $3,749,000 related to sudocetaxel zendusortide material and expenses of $536,000 related to the production of bacteriostatic water for injection ("BWFI"). Excluding these expenses, R&D expenses are down significantly in the three- and nine-month periods of 2023 compared to last year, mostly as a result of lower spending on our oncology program. R&D expenses also include $508,000 in severance and other expenses related to the reorganization announced in July 2023.

Selling Expenses

Selling expenses decreased to $6,728,000 and $20,021,000 for the three- and nine-month periods ended August 31, 2023, compared to $8,404,000 and $31,582,000 for the same periods last year. The decrease in selling expenses in the third quarter ended August 31, 2023 is mainly related to higher expenses incurred in the same period of 2022 related to the setting up of our internal field force in the United States as well as severance costs incurred following our decision in 2022 to exit the European market for the commercialization of Trogarzo. The decrease in the nine-month period ended August 31, 2023 is due in large part to a charge of $6,356,000 related to the accelerated amortization, in Q2 2022 of the Trogarzo commercialization rights for the European territory following our decision to cease commercialization activities in that territory during that quarter, which also led to decreased overall spending in commercialization activities. In 2022, we also incurred one-time costs related to setting up our internal field force in the United States. Selling expenses also include $141,000 in severance and other expenses related to the reorganization announced in July 2023.

The amortization of the intangible asset value for the EGRIFTA SV and Trogarzo commercialization rights is also included under selling expenses. As such, we recorded amortization expenses of $675,000 and $2,153,000 for the three- and nine-month periods ended August 31, 2023, compared to $642,000 and $8,539,000, respectively, in 2022.

General and Administrative Expenses

General and administrative expenses in the three- and nine-month periods ended August 31, 2023, amounted to $3,710,000 and $11,878,000, respectively, compared to $4,209,000 and $13,400,000 reported in the comparable periods of fiscal 2022. The decrease in general and administrative expenses is largely due to our decision to terminate the commercialization activities of Trogarzo in Europe during the second quarter of 2022. General and administrative expenses also include $70,000 in severance and other expenses related to the reorganization announced in July 2023.

Net Finance Costs

Net finance costs for the three- and nine-month periods ended August 31, 2023, were $674,000 and $7,557,000, respectively, compared to $1,879,000 and $4,808,000 for the comparable periods of 2022. Net finance costs in the third quarter of 2023 included interest of $2,244,000, consisting of interest on the convertible senior notes issued in June 2018 of $128,000, and interest of $2,116,000 on the Loan Facility. Net finance costs in the nine-month period ended August 31, 2023 included interest of $5,802,000, consisting of interest on the convertible senior notes issued in June 2018 of $916,000 and interest on the Loan Facility of $4,986,000. Net finance costs were also impacted in the nine-month period ended August 31, 2023, by the loss on debt modification of $2,650,000 related to the issuance of the 5,000,000 common share purchase warrants (the "Marathon Warrants") issued in connection to the amendments to the Loan Facility during the first quarter of 2023. This was offset by a net gain on financial instruments carried at fair value of $1,939,000 in the three-month period ended August 31, 2023, and of $2,054,000 in the nine-month period ended August 31, 2023.

Net finance costs for the three- and nine-month periods ended August 31, 2023, also included accretion expense of $500,000 and $1,642,000, respectively, compared to $515,000 and $1,576,000 for the comparable periods in 2022.

Adjusted EBITDA

Adjusted EBITDA was $2,160,000 for the third quarter of fiscal 2023 and $(7,872,000) for the nine-month period ended August 31, 2023, compared to $(3,851,000) and $(19,649,000) for the same periods of 2022. Adjusted EBITDA in the first and second quarters of 2023 was negatively affected by expenses of $3,749,000 related to sudocetaxel zendusortide material and expenses of $536,000 related to the production of BWFI. No such expenses were recorded in the third quarter of 2023. See "Non-IFRS and Non-US-GAAP Measure" and "Reconciliation of Adjusted EBITDA" below for a reconciliation to Net Loss for the relevant periods.

Net Loss

Net loss for the three- and nine-month periods ended August 31, 2023, amounted to $746,000 and $21,202,000, respectively, compared to $7,549,000 and $39,308,000, for the same periods in 2022.

Financial Position, Liquidity and Capital Resources

Going Concern Uncertainty

As part of the preparation of our Interim Financial Statements, management is responsible for identifying any event or situation that may cast doubt on the Company’s ability to continue as a going concern. Substantial doubt regarding the Company’s ability to continue as a going concern exists if events or conditions, considered collectively, indicate that the Company may be unable to honor its obligations as they fall due during a period of at least, but not limited to, 12 months from August 31, 2023. If the Company concludes that events or conditions cast substantial doubt on its ability to continue as a going concern, it must assess whether the plans developed to mitigate these events or conditions will remove any possible substantial doubt.

For the nine-month period ended August 31, 2023, the Company incurred a net loss of $21,202,000 (2022 – $39,308,000) and had negative operating cash flows of $1,572,000 (2022 – $9,491,000). On July 3, 2023, the Company defaulted under the minimum liquidity covenant (the "Liquidity Breach") of the Loan Facility (as defined in Note 7 to the Interim Financial Statements) resulting in the lender having the ability to demand immediate repayment of the debt and in making available to the lender the collateralized assets, which include substantially all cash, bonds and money market funds which are subject to control agreements. Accordingly, the Loan Facility has been classified as a current liability and, as a result, the Company’s total current liabilities exceeded total current assets at August 31, 2023. On September 21, 2023, the Company obtained a waiver from the lender relating to the Liquidity Breach. Refer to Subsequent events in Note 15 of the Interim Financial Statements.

The Company’s Loan Facility is available in four tranches and contains various covenants, including minimum liquidity covenants whereby the Company needs to maintain significant cash, cash equivalent and eligible short-term investments balances in specified accounts, which restricts the management of the Company’s liquidity (refer to Notes 18 and 24 of the annual consolidated financial statements as at November 30, 2022). A Liquidity Breach also entitles the lender to halt the advance of additional tranches and may trigger an increase of 300 basis points of the interest rate on the outstanding loan balance. In July 2023, the Company and the lender amended the terms of the Loan Facility to reduce the minimum liquidity covenant for the period of July 10 to July 28, 2023, and entered into an additional amendment to the terms of the Loan Facility to provide for the minimum liquidity covenant to be $15,000,000 from July 29, 2023, to October 31, 2023. After such date, the minimum liquidity covenant will revert to $20,000,000; provided, however, that if the F8 Formulation is not approved by the FDA by March 31, 2024, the minimum liquidity covenant will be set at $30,000,000. The Loan Facility also includes operational milestones and required revenue targets (which were amended during the second quarter, refer to Note 7 of the Interim Financial Statements) in order for the Company to comply with the conditions of the Loan Facility and to borrow money forming part of the various tranches. Furthermore, the Loan Facility includes a covenant prohibiting having a going concern explanatory paragraph in the annual report of the independent registered public accounting firm but the lender amended the Loan Facility on February 27, 2023 to exclude the fiscal year ended November 30, 2022 from this prohibition. Notwithstanding the agreement in principle reached on September 24, 2023, there is no assurance that the lender will agree to amend or to waive any future potential covenant breaches, if any.

The Company’s ability to continue as a going concern for a period of at least, but not limited to, 12 months from August 31, 2023, involves significant judgement and is dependent on its ability to obtain the support of the lender (including possible waivers and amendments), increase its revenues and the management of its expenses to generate sufficient positive operating cash flows and to find alternative source of funding to respect the various covenants of its Loan Facility, including obtaining the approval from the FDA for its F8 Formulation on or before March 31, 2024. Management’s plans include current negotiations with its lender to obtain amendments to its Loan Facility, exploring additional alternative sources of funding, including raising additional equity, and to generate positive operating cash flows. Some elements of these plans are outside of management’s control and the outcome cannot be predicted at this time. Should management’s plans not materialize, the Company may be in default of the Loan Facility, be forced to reduce or delay expenditures and capital additions and seek additional alternative financing, or sell or liquidate its assets. As a result, there is material uncertainty related to events or conditions that cast substantial doubt about the Company’s ability to continue as a going concern.

The Interim Financial Statements have been prepared assuming the Company will continue as a going concern, which assumes the Company will continue its operations in the foreseeable future and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. The Interim Financial Statements do not include any adjustments to the carrying values and classification of assets and liabilities and reported expenses that might result from the outcome of this uncertainty and that may be necessary if the going concern basis was not appropriate for the Interim Financial Statements. If the Company was unable to continue as a going concern, material impairment of the carrying values of the Company’s assets, including intangible assets, could be required.

Analysis of cash flows

We ended the third quarter of fiscal 2023 with $22,874,000 in cash, bonds and money market funds. Available cash is invested in highly liquid fixed income instruments including governmental and municipal bonds, and money market funds. The Company currently is required to maintain $15,000,000 in cash, bonds and money market funds up to and including October 31, 2023, and, thereafter, $20,000,000, to respect its minimum liquidity covenant.

The Company voluntarily changed its accounting policy in fiscal 2022 to classify interest paid and received as part of cash flows from operating activities, which were previously classified as cash flow from financing activities and interest received as cash flows from investing activities. The fiscal 2022 amounts presented herein have been recast to reflect the change in policy.

For the three-month period ended August 31, 2023, cash flows from operating activities were $5,329,000, compared to ($1,572,000) in the comparable period of fiscal 2022.

In the third quarter of fiscal 2023, changes in operating assets and liabilities had a positive impact on cash flow from operations of $5,329,000 (2022-negative impact of $2,757,000). These changes included positive impacts from a decrease in inventories ($2,439,000), lower trade and other receivables ($4,445,000), lower prepaid expenses and deposits ($958,000) and included a negative impact from accounts payable ($2,947,000). The decrease in inventories was mainly due to a planned reduction of Trogarzo inventory levels. Higher provisions also had a positive impact on cash flow of $1,687,000.

During the third quarter of fiscal 2023, the Company received net proceeds of $19,700,000 from the draw-down of the second tranche under the Loan Facility. On June 30, 2023, we redeemed the remaining $27,452,000 of convertible senior notes. As at August 31, 2023, no convertible senior notes remained outstanding. During the third quarter of fiscal 2022, the Company realized net proceeds from the issuance of a long-term loan of $37,715,000. Significant uses of cash for financing activities during fiscal 2022 included the purchase of convertible senior notes for $28,746,000 (including costs related to the purchase), and $1,225,000 in deferred financing costs related to the establishment of the Loan Facility. There were no other significant financing activities or investing activities in the three and nine months ended August 31, 2023, and 2022.
