LYON, France–(BUSINESS WIRE)–POXEL SA (Euronext: POXEL – FR0012432516), a clinical stage biopharmaceutical company developing innovative treatments for chronic serious diseases with metabolic pathophysiology, including non-alcoholic steatohepatitis (NASH) and rare metabolic disorders, today announced its financial results for the period ended June 30, 2022 and provided a corporate update.

Thomas Kuhn, Chief Executive Officer of Poxel, stated: “Thus far, 2022 has been marked by important achievements for Poxel. On the clinical front, our Phase 2 NASH DESTINY-1 trial for PXL065 met its objectives demonstrating a statistically significant effect with a favorable safety profile. Based on these positive results, PXL065 will be prioritized for further development in NASH and we will initiate discussions for a potential pivotal program in NASH. In parallel, we will focus PXL770 development efforts exclusively in rare diseases on the basis of our promising data which demonstrated strong potential in multiple rare metabolic indications. In addition, these recent PXL065 results have validated our hypothesis that the deuterated-thiazolidinediones (d-TZD) platform reduces PPARγ side-effects while retaining the efficacy benefits of TZDs, and thus warrants exploration in other diseases, such as ALD. Over the summer, we also extended our cash runway through the restructuring of our debt and an equity-linked financing facility. This accomplishment provides us further flexibility to secure additional financing solutions necessary to execute our rare disease strategy.”

H1 Key Events

Clinical Updates

• In ALD, PXL770 is prepared to advance into a Phase 2a biomarker proof-of-concept (POC) clinical trial in male patients with adrenomyeloneuropathy (AMN), the most common ALD subtype. The 12-week study will evaluate pharmacokinetics, safety and potential for efficacy based on relevant disease biomarkers, such as the effect on very long chain fatty acids (VLCFA), the characteristic plasma marker of the disease. Considering the DESTINY-1 results for PXL065 in NASH, which validated the deuterium-modified thiazolidinedione (TZD) platform, a second identical study continues to be planned in order to assess the potential of the deuterium-modified TZD platform with PXL065 in ALD. ALD studies are expected to initiate as soon as possible, subject to additional financing.
• In February and April, the FDA awarded Fast Track Designation (FTD) to PXL065 and PXL770 respectively, for ALD. The FDA grants FTD to investigational drugs which treat a serious or life-threatening condition, and which fill an unmet medical need. Filling an unmet medical need is defined as providing a therapy where none exists or providing a therapy which may be potentially better than available therapy. The key benefits of FTD comprise enhanced access to the FDA, with regular and more frequent opportunities for consultation and discussion.
• In May, the FDA granted Orphan Drug Designation (ODD)¹ to PXL065 and PXL770 for ALD. ODD confers a company a potential seven-year window of exclusive marketing rights following FDA approval, along with a reduction in certain application fees, and tax credits for expenses related to qualified clinical trials conducted after orphan designation is received.
• Two preclinical articles on X-Linked Adrenoleukodystrophy (ALD) for PXL065 and PXL770 were published:
  • The article on PXL065 was published in The Journal of Inherited Metabolic Disease (“JIMD”) and is entitled “Therapeutic potential of deuterium-stabilized (R)-pioglitazone – PXL065 – for X-linked adrenoleukodystrophy”. It is available here: https://pubmed.ncbi.nlm.nih.gov/35510808/.
  • The article on PXL770 was published in The Journal of Pharmacology and Experimental Therapeutics (“JPET”), and is entitled “Beneficial effects of the direct AMP-Kinase activator PXL770 in in vitro and in vivo models of X-Linked Adrenoleukodystrophy”. It is available here: https://jpet.aspetjournals.org/content/early/2022/06/25/jpet.122.001208.

• In ADPKD, preclinical studies were completed and demonstrated efficacy of PXL770 in in vitro cyst assays including ADPKD patient-derived cells. In vivo efficacy in a classical animal model of ADPKD was also observed including improvements in renal function, kidney weight, cyst index, and other benefits in kidney tissues. Initiation of development planning and regulatory interactions is underway.

Corporate Update

• In June, the U.S. Patent and Trademark Office (PTO) issued a new patent for PXL065 that describes a specific form of PXL065 with unique properties. Importantly, this recently issued patent provides additional protection through 2041 and could expand protection for PXL065 worldwide, with the potential for an additional 5 years through patent term extension.
• On June 21, Poxel held its annual general meeting. The shareholders approved all the resolutions that were recommended by the Board of Directors. For further information, please visit: https://www.poxelpharma.com/en_us/investors/shareholder-information/annual-general-meeting-documents.

Significant Events after the Period

NASH

• In August, the topline results for the Phase 2 trial for the treatment of NASH (DESTINY-1) for PXL065 were announced and indicated that the primary efficacy endpoint was met. PXL065-treated patients achieved statistically significant improvements in the relative decrease in liver fat content measured by magnetic resonance imaging estimated proton density fat fraction (MRI–PDFF) at 36-weeks for all doses. PXL065 was observed to be safe and well tolerated with no dose-dependent increase in body weight and no increased lower extremity edema vs. placebo. The safety profile is consistent with reduced PPARγ-mediated side effects vs. published results of pioglitazone.
• On September 21, the Company announced additional DESTINY-1 results including histology. Histology findings from paired liver biopsies showed strong improvement in fibrosis without worsening of NASH, consistent with dose-dependent reduction of all biomarkers related to fibrinogenesis and fibrosis risk scores. Additional favorable trends in other histology parameters were observed. Additional dose-dependent benefits on glucose control and indices of insulin sensitivity were also observed.

TWYMEEG^® (Imeglimin)

• As of September 1^st, initial launch year restrictions for TWYMEEG which limited new products to two weeks prescriptions have been lifted. Due to Sumitomo Pharma’s promotional activities and efforts since launch in September 2021, TWYMEEG is very well known among prescribers. Sumitomo Pharma’s commercial efforts continue to leverage TWYMEEG’s potential to be used both in combination with other treatments, such as DPP4i’s, which are the most prescribed treatments for Japanese Type-2-Diabetes patients, and as monotherapy.

Financing

• In August, the Company announced that it restructured its debt with IPF, resulting in the postponement of the Q3 2022 and Q4 2022 amortization payments under the existing debt facility, and lowering certain financial covenants until the end of January 2023. As part of the restructuring, the Company agreed to certain additional commitments which include the increase of the amounts due to IPF and potential partial early repayments of the debt.
• Concurrently, the Company entered into an equity-linked financing arrangement with IRIS for an initial gross amount of EUR 4 million, with the option, at the latest on December 31, 2022 and, at the Company’s sole discretion, to draw a second and third tranche of up to EUR 1 million each.
• As a result of these two agreements, the Company’s expects that its resources will be sufficient to fund its operations and capital expenditure requirements through at least February 2023.
