SIK2

FRISCO, Texas, June 24, 2022 /PRNewswire/ -- Green3Bio, a subsidiary of Greenfire Bio , today announced a publication in the Journal of Clinical Investigation1 led by researchers at The University of Texas MD Anderson Cancer Center demonstrating that SIK2 inhibitors, including GRN-300 sensitized ovarian and triple-negative breast cancer (TNBC) cells and xenografts to PARP inhibitors. Zhen Lu, M.D., and Robert Bast, M.D., and colleagues demonstrated that a combination of PARPi and SIKi provides a novel therapeutic approach to enhance PARPi sensitivity in ovarian cancers that initially respond to PARPi and eventually develop drug resistance. The major findings from the preclinical research study include: GRN-300 treatment sensitizes ovarian and breast cancer cells by enhancing olaparib-mediated inhibition of PARP enzyme activity The transcription of DNA repair and apoptosis genes is regulated by SIK2 inhibition by GRN-300 GRN-300 enhances olaparib-induced DNA DSB (double-strand break) and apoptosis Co-administration of GRN-300 and olaparib is synergistic in inhibiting tumor growth in animal models of ovarian cancer and TNBC. These findings provide strong preclinical evidence supporting future clinical trials to determine whether the combination will benefit patients with ovarian and triple negative breast cancers. Animal studies, particularly those with olaparib and GRN-300, did not show significant toxicity based on weight loss. Pre-clinical toxicology studies in rodents and dogs showed no hematologic toxicity, which is particularly important for combination with PARPi. "Patients with ovarian and triple-negative breast cancers are in great need for more effective treatments due to the high prevalence of acquired resistance to standard therapies that involve PARP inhibition," said Steve Morris, MD (Chairperson, Scientific Advisory Board of Greenfire Bio). He added, "The GRN-300 preclinical data published in The Journal of Clinical Investigation shows the potential of GRN-300 and its unique mechanism of action through SIK2/3 inhibition to help change the combination treatment paradigm in gynecologic and breast cancers, irrespective of BRCA mutation status." Ajit Gill, CEO and founder of Greenfire Bio, commented that "This publication provides further support for the development of our clinical asset GRN-300. We believe this agent has the potential to improve treatment of ovarian and other cancers - both as a single agent and in combination with existing therapies such as the PARP inhibitor olaparib that is indicated for the treatment of ovarian and breast cancers under the tradename Lynparza." These data further support the preclinical proof-of-concept for SIK2 inhibitors as potential cancer therapeutics in combination with carboplatin for hard-to-treat ovarian cancer, recently published in Cancers, and they support the continued efforts in our first-in-human clinical trial ongoing at MD Anderson. About Ovarian Cancer According to the American Cancer Society2, ovarian cancer ranks fifth in cancer deaths among women. They estimate that in 2022 there will be about 19,880 new cases of ovarian cancer diagnosed in the United States and that about 12,810 will die of the disease. According to the World Cancer Research Fund International3, there were about 313,000 new cases of ovarian cancer diagnosed worldwide in 2020. Ovarian cancer is difficult to detect at an early, more treatable stage; therefore, the current lack of salvage treatment for women, who experience a recurrence, results in a 5-year survival rate of less than 30%. About GRN-300 GRN-300 (previously ARN3261) is an orally bioavailable first-in-class novel, small molecule, dual inhibitor of the salt-inducible kinases 2 and 3 (SIK2, SIK3). This agent has the potential to overcome chemoresistance based on its mechanism of action (MOA) and synergistic effects with standard of care including paclitaxel, carboplatin, PARP inhibitors, and immune checkpoint inhibitors (ICIs). SIK2 is overexpressed in 30% of ovarian cancer specimens suggesting a multifunctional role of SIK2/3 in tumorigenesis. SIK2 and SIK3 are known to play [an] oncogenic role in other tumor types, including prostate cancer, breast cancer, diffuse large B-cell lymphoma, and melanoma. Higher levels of expression of SIK2 have been shown to be significantly correlated with poor progression-free survival in patients with high-grade serous ovarian cancers. GRN-300 attenuated tumor growth & inhibition in several preclinical xenograft ovarian cancer models as a single agent and in combination with paclitaxel. The clinical activity of GRN-300 as a single agent and in combination with paclitaxel is currently being evaluated in a Phase 1a/1b Clinical Study in subjects with Recurrent Ovarian, Primary Peritoneal, and Fallopian Tube Cancers (ClinicalTrials.gov Identifier: NCT04711161). About Greenfire Bio Greenfire Bio, led by a team of experienced biopharma executives, is building a diversified portfolio of oncology products through in-licensing, acquisition, and partnering, and is advancing them through clinical proof of concept. About Green3Bio Green3Bio is a subsidiary of Greenfire Bio. Green3Bio is developing GRN300 through clinical trials with the expertise of Greenfire Bio team members. The currently ongoing clinical trial (ClinicalTrials.gov Identifier: NCT04711161) is sponsored by Green3Bio. 1 J Clin Invest. 2022;132(11):e146471 2 3 CONTACT: Ajit Gill, President and CEO of Greenfire Bio at [email protected].

FRISCO, Texas, May 31, 2022 /PRNewswire/ -- Greenfire Bio, LLC announced today that its subsidiary, Green3Bio, and its collaborators at MD Anderson Cancer Center will present an update on the ongoing first-in-human clinical trial of GRN-300 at the upcoming ASCO 2022 Annual Meeting. GRN-300 is a first-in-class, orally bioavailable novel small molecule inhibitor of the Salt Inducible Kinases 2 and 3 (SIK2/SIK3) that is highly expressed in ovarian cancer and has been identified to play a pivotal role in several other cancers. The transition of this emerging biologic pathway and a novel agent into the clinic marks a successful step in the progress of the GRN-300 program. The goal of the clinical study is to determine the recommended Phase 2 Dose (RP2D), safety/tolerability and the tumor response of GRN-300 as a monotherapy or in combination with paclitaxel in subjects with ovarian cancer. This study is registered at ClinicalTrials.gov Identifier: NCT04711161.

Webcast presentation tomorrow, 6 August 2021, at 14.00 CET / 8 AM ET, , +32 2 793 38 47, code 8245817 Mechelen, Belgium; 5 August 2021, 22.01 CET; regulated information – Galapagos NV (Euronext & NASDAQ: GLPG) is pleased to report progress on earlier-stage programs as well as its commercial launch of filgotinib in Europe. Following recent setbacks, the company is moving forward with its revised strategy and operational restructuring announced in May. The unaudited H1 financial and operational results are further detailed in the H1 2021 report available on the website, . “Multiple assets are moving through clinical development, and we recently reported positive topline data on our TYK2 compound GLPG3667. In a Phase 1b trial in psoriasis (Pso), clinical activity was observed at 4 weeks, combined with an encouraging safety and tolerability profile. We currently are running an extended dose escalation study in healthy volunteers, and plan to progress GLPG3667 to a Phase 2b dose finding study in Pso as well as a Phase 2 study in ulcerative colitis (UC) in 2022. We continue to develop our SIK portfolio of molecules, and recently reported encouraging early data from the first patient studies with SIK2/3 inhibitor GLPG3970. In a Phase 1b trial in Pso (CALOSOMA), clinical activity was observed at 6 weeks, and in a Phase 2a trial in UC (SEA TURTLE), biologically important effects were observed on a number of objective endpoints, both of which point to the potential of SIK inhibition as a novel mode of action in inflammation. No activity was observed in the LADYBUG study in rheumatoid arthritis (RA). GLPG3970 was generally safe and well tolerated. Based on these encouraging data, we work on optimizing the pharmacology of follow-up compounds from our SIK portfolio, and plan to bring an improved SIK2/3 molecule into the clinic in 2022. On the commercial side, we report rapid progress in establishing our commercial operations for Jyseleca across Europe, with 11 countries launched to date. Reimbursement procedures are on track, and we are on target to achieve our commercial objectives. We remain excited about the potential of our target discovery platform, our drug development capabilities, and the strength of our teams. We want to thank our shareholders for their continued support and patience as we are working hard to build our pipeline and establish Galapagos as a fully integrated European biopharma,” said Onno van de Stolpe, CEO of Galapagos. Bart Filius, President and COO, added, “Following the strategic exercise announced at Q1, we are focused on advancing our pipeline, implementing our savings program, and diligently evaluating business development opportunities. At the same time, we have been delivering on the launch of Jyseleca, building out our organization in new European markets. In line with our review, we reiterate our 2021 operational cash burni guidance of between €580 million and €620 million. We believe that the decisions and actions taken put us on the strongest footing for the future. We look forward to a busy second half of the year, not the least of which is the expected outcome of the regulatory review in Europe of Jyseleca in UC.” Key figures first half-year report 2021 (unaudited)(€ millions, except basic & diluted loss per share) (*) The 2020 comparatives have been restated to consider the impact of classifying the Fidelta business as discontinued operations in 2020. Details of the financial resultsDue to the sale of our fee-for-service business (Fidelta) to Selvita on 4 January 2021 for a total consideration of €37.1 million (including customary adjustments for net cash and working capital), the results of Fidelta are presented as “Net profit from discontinued operations” in our unaudited condensed consolidated income statements for the six months ended 30 June 2021 and 30 June 2020. Revenues and other income from continuing operationsOur revenues and other income from continuing operations for the first six months of 2021 increased to €277.2 million compared to €217.2 million in the first six months of 2020. Our revenues from the Gilead collaboration in the first six months of 2021 (€253.2 million) related to (i) the exclusive access to our drug discovery platform (€115.7 million), (ii) the filgotinib revenue recognition (€136.1 million) and (iii) royalties (€1.4 million). Our deferred income balance on 30 June 2021 includes €1.9 billion allocated to our drug discovery platform that is recognized linearly over 10 years, and €0.7 billion allocated for the filgotinib development (including considerations for the previous and the renegotiated collaboration combined) that is recognized over time until the end of the development period. Results from continuing operationsWe realized a net loss from continuing operations of €77.2 million for the first six months of 2021, compared to a net loss of €169.2 million for the first six months of 2020. We reported an operating loss amounting to €97.6 million for the first six months of 2021, compared to an operating loss of €134.4 million for the same period last year. Our R&D expenditure in the first six months of 2021 amounted to €268.8 million, compared to €262.9 million for the first six months of 2020. This increase, primarily related to our filgotinib program and our Toledo program, was compensated by a decrease for ziritaxestat, the osteoarthritis (OA) program with GLPG1972, and the program in atopic dermatitis (AtD) with MOR106. Personnel costs increased due to an increase in headcount compared to the same period last year and increased costs of our subscription right plans. This factor, and the increased cost of the commercial launch of filgotinib in Europe, contributed to the increase in our S&M and G&A expenses, which were respectively €29.1 million and €76.9 million in the first six months of 2021, compared to respectively €26.9 million and €61.8 million in the first six months of 2020. We reported a non-cash fair value gain from the re-measurement of initial warrant B issued to Gilead, amounting to €2.8 million, mainly due to the decreased implied volatility of the Galapagos share price and its evolution between 31 December 2020 and 30 June 2021. Net other financial income in the first six months of 2021 amounted to €17.1 million, compared to net other financial loss of €13.0 million for the first six months of 2020, which was primarily attributable to €33.4 million of currency exchange gain on our cash and cash equivalents and current financial investments in U.S. dollars, to €8.7 million of negative changes in (fair) value of current financial investments and financial assets and to €4.4 million of interest expenses. The other financial expenses also contained the effect of discounting our long term deferred income of €4.8 million. Results from discontinued operationsThe net profit from discontinued operations for the six months ended 30 June 2021 consisted of the gain on the sale of Fidelta, our fee-for-services business, for €22.2 million. Group net resultsWe reported a group net loss for the first six months of 2021 of €55.0 million, compared to a group net loss of €165.6 million for the first six months of 2020. Cash positionCurrent financial investments and cash and cash equivalents totaled €5,006.6 million on 30 June 2021, as compared to €5,169.3 million on 31 December 2020. Total net decrease in cash and cash equivalents and current financial investments amounted to €162.7 million during the first six months of 2021, compared to a net decrease of €214.3 million during the first six months of 2020. This net decrease was composed of (i) €223.2 million of operational cash burn, (ii) offset by €2.6 million of cash proceeds from capital and share premium increase from exercise of subscription rights in the first six months of 2021, (iii) €5.8 million negative changes in (fair) value of current financial investments and €35.0 million of mainly positive exchange rate differences, (iv) €28.7 million cash in from disposal of subsidiaries, net of cash disposed. Finally, our balance sheet on 30 June 2021 held a receivable from the French government (Crédit d’Impôt Rechercheiv) and a receivable from the Belgian Government for R&D incentives, for a total of both receivables of €142.7 million. Outlook 2021In 2021, we expect the European regulatory assessment of filgotinib for the treatment of UC and anticipate both an opinion from the Committee for Medicinal Products for Human Use (CHMP) and a decision from the European Commission later this year. We also expect additional reimbursement decisions for filgotinib in RA across a number of European countries. We are on track to complete the transition from our collaboration partner Gilead to us of the full European commercial operations for filgotinib by year-end, and we anticipate reporting on our own European sales of filgotinib starting in the second half of the year. Completion of the recruitment in the global DIVERSITY Phase 3 trial with filgotinib in Crohn’s disease by our collaboration partner Gilead is also expected later this year. With regard to our SIK portfolio, we are advancing our SIK3 inhibitor GLPG4399 in healthy volunteers this year, and we aim to advance a follow-up SIK2/3 preclinical candidate into the clinic in 2022. Following the positive topline data from our TYK2 inhibitor, GLPG3667, we currently are running an extended dose escalation study in healthy volunteers, and we are preparing for a Phase 2b trial in Pso and a Phase 2 trial in UC next year. In our other programs, by year-end we intend to finalize recruitment into the GLPG2737 Phase 2a trial in polycystic kidney disease. Following the previously announced review of our plans for 2021, we reiterate our guidance for full year 2021 operational cash burn of €580 to €620 million.
