(Nasdaq: GTHX), a commercial-stage oncology company focused on delivering next-generation therapies that improve the lives of those affected by cancer, and Pharmacosmos A/S, a leader in the development of innovative treatments for patients suffering from iron deficiency and iron deficiency anemia, today announced that they have entered into a definitive merger agreement under which Pharmacosmos A/S, through its U.S. subsidiary Pharmacosmos Therapeutics Inc., will acquire all outstanding shares of G1 Therapeutics common stock for U.S. $7.15 per share in cash for a total equity value of approximately $405 million, which represents a 68% premium to G1’s closing share price on August 6, 2024 and a 133% premium to G1’s prior 30-day volume weighted average price. The Boards of Directors of the parties have unanimously approved the transaction, which is expected to close late in the third quarter of 2024. G1’s COSELA is the first and only product approved by the U.S. Food and Drug Administration to decrease the incidence of chemotherapy-induced myelosuppression in adult patients when administered prior to a platinum/etoposide-containing regimen or topotecan-containing regimen for extensive-stage small cell lung cancer (ES-SCLC). Together, Pharmacosmos and G1 Therapeutics will execute on the shared vision to grow and accelerate the availability of COSELA for all appropriate patients with ES-SCLC. G1 brings a well-established and successful commercial, sales, and medical platform to Pharmacosmos, which has complementary expertise in commercializing hematology and supportive care products, a robust global commercial presence, and significant resources to maximize the penetration of COSELA into the ES-SCLC market. Together, the combined company will be able to optimize the commercial reach to oncologists and expand the availability of COSELA among patients living with ES-SCLC. “G1 and Pharmacosmos have a shared commitment to people living with cancer; the transaction announced today will enable a more rapid uptake of COSELA into the ES-SCLC market to maximize availability for patients who need this important drug,” said Jack Bailey, Chief Executive Officer of G1 Therapeutics. “Importantly, this acquisition delivers significant value to G1’s stakeholders by providing better and broader access to this important product for the cancer patients we seek to treat and a significant premium to our shareholders. I am proud of all that the G1 team has accomplished over the years, thankful for their great effort, and excited about what’s possible by the combined Pharmacosmos/G1 team as we meet the needs of more cancer patients." “The acquisition of G1 Therapeutics Inc., its intellectual property, and the addition of COSELA® (trilaciclib) to our portfolio of innovative products is transformative for Pharmacosmos. By combining our existing colleagues with the great team at G1 Therapeutics, we will meaningfully expand our organization serving oncologists in the US. This will enable broader and better access for patients in need of COSELA as well as for our existing FDA approved drug, Monoferric® (ferric derisomaltose),” said Tobias S. Christensen, President and Chief Executive Officer of Pharmacosmos A/S. “COSELA is a first-in-class product that brings important benefits to patients and fits very nicely together with our lead product Monoferric® (ferric derisomaltose). While Monoferric is available around the World, COSELA is so far only approved in the US and in China. It will be a focus for us to bring this important product to more patients both in US and worldwide to help minimize the number of lung cancer patients suffering from myelosuppression after chemotherapy.” Transaction Terms Under the terms of the merger agreement, Pharmacosmos has agreed to commence a cash tender offer to acquire all issued and outstanding shares of G1 common stock for US $7.15 per share in cash. The transaction will be fully financed by Pharmacosmos’ existing cash on hand and existing corporate credit facilities. The closing of the tender offer will be subject to customary conditions, including the tender of shares which represent at least a majority of the total number of G1’s outstanding shares of common stock and the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act. Upon successful completion of the tender offer, Pharmacosmos would acquire all shares not acquired in the tender offer through a second-step merger for the same consideration that the tendering stockholders will receive in the tender offer. It is anticipated the transaction will close late in the third quarter of 2024. Upon completion of the transaction, G1’s common stock will no longer be publicly listed. As previously announced, G1 will be releasing its second quarter 2024 financial results and filing its Form 10-Q Quarterly Report tomorrow. However, due to the pending transaction, we will no longer be hosting a conference call at 8:30 am ET, August 8 to review such results.

The 2023 European Society of Cardiology (ESC) guidelines for acute and chronic heart failure (HF) include upgraded recommendations for intravenous (IV) iron supplementation, including Ferinject® (ferric carboxymaltose), for the management of iron deficiency in patients with HF. Phase IV HEART-FID study results and ferric carboxymaltose meta-analysis also presented at 2023 ESC Congress ST. GALLEN, Switzerland, Aug. 28, 2023 /PRNewswire/ -- CSL Vifor is pleased to announce that the European Society of Cardiology (ESC) have upgraded recommendations in the ESC 2023 guidelines for the treatment of iron deficiency acute and chronic HF with IV iron supplementation, including Ferinject®. The guidelines include higher level of recommendations and address a broader patient group for the management of iron deficiency in HF patients with compromised heart function (HFrEF and HFmrEF). Intravenous iron supplementation is recommended in symptomatic patients with HFrEF and HFmrEF, and iron deficiency, to alleviate HF symptoms and improve quality of life. (Class I, level A) Intravenous iron supplementation with ferric carboxymaltose or ferric derisomaltose should be considered in symptomatic patients with HFrEF and HFmrEF, and iron deficiency, to reduce the risk of HF hospitalization, irrespective of hospitalisation history (Class IIa, level A). "We are pleased that ESC's new heart failure guidelines have been updated to reflect the latest scientific evidence," said Fabio Dorigotti, Head of Global Medical Affairs at CSL Vifor. "Improving iron deficiency diagnosis followed by IV iron supplementation based on the updated guidelines means more patients may potentially benefit from IV iron treatment. We are particularly pleased with the updated recommendations for IV iron including Ferinject® in the new 2023 focused update of the 2021 treatment guidelines. This revision will enable cardiologists and physicians to better treat more of the symptomatic heart failure patients with iron deficiency." In addition, findings from the phase IV HEART-FID trial (NCT03037931) of ferric carboxymaltose were presented at the ESC congress 2023 in Amsterdam, Netherlands, and simultaneously published in the peer-reviewed medical journal New England Journal of Medicine.1 HEART-FID is the largest and longest duration trial to date evaluating IV iron in HF patients with reduced ejection fraction and iron deficiency. The trial approached but did not meet the pre-specified statistical significance of p<0.01 on the primary endpoint, which was a hierarchical composite of death and HF hospitalization at 12 months and change from baseline to 6 months in the 6-minute walk test distance (6-MWD). The results showed that with ferric carboxymaltose, there were numerically fewer deaths and hospitalizations for HF through 12 months and a modest benefit in the 6-MWD at 6 months compared to placebo. Ferric carboxymaltose was generally well tolerated and without unexpected safety findings. "While the results from the HEART-FID study did not meet statistical significance at the pre-specified level, the totality of evidence with ferric carboxymaltose from prior studies assessing symptomatic and functional status endpoints – combined with recent clinical outcomes studies – show overall safety and potential benefits," said Robert Mentz, MD, Chief of the Heart Failure Section at Duke University Medical Center, Durham, US, and Clinical Lead for the trial. To understand these new results in light of the totality of the evidence for IV iron in HF patients with iron deficiency, investigators also executed a pooled analysis using individual participant data from the three long-term trials FAIR-HF, CONFIRM-HF and HEART-FID of ferric carboxymaltose with a total of 4'501 patients. It represents the largest analysis to date to examine the effects of ferric carboxymaltose on clinical outcomes and was presented at the ESC congress 2023 with a parallel acceptance of the manuscript in the peer-reviewed European Heart Journal.2 Treatment with ferric carboxymaltose in iron-deficient HF patients with reduced or mildly reduced left ventricular ejection fraction was associated with a reduction in the composite endpoint of total cardiovascular hospitalizations and cardiovascular death compared with placebo, and with significantly reduced risks of hospitalization due to heart failure or cardiovascular causes, with no effect on survival. "One in two patients with chronic HF has iron deficiency, with a significant number of patients not being diagnosed or inadequately treated for iron deficiency," commented Steve Pascoe, MD, Senior Vice President, Clinical and Therapeutic Area Strategy, CSL. "We are confident that the outcomes of this trial and the pooled analysis of ferric carboxymaltose are an important contribution to the growing body of evidence showcasing the advantages of IV iron treatment for HF patients."

About the ESC guidelines The ESC HF guidelines aim to provide practical, evidence-based recommendations for the diagnosis and treatment of HF, thereby improving and harmonizing standards of diagnosis and treatment of cardiovascular diseases for physicians, and potentially optimizing patient care. The ESC HF guidelines are updated periodically, with the 2023 version updated at the ESC congress end of August 2023. About HEART-FID HEART-FID is the first randomized clinical trial powered to evaluate the effects of intravenous ferric carboxymaltose on a hierarchical endpoint of death, heart failure hospitalizations, and functional status for adult patients with iron deficiency. The multicenter, randomized, double-blind, placebo-controlled trial enrolled 3,065 patients at 281 international centers. Eligible patients were at least 18 years old in stable chronic heart failure with New York Heart Association functional class II to IV symptoms, ejection fraction ≤40%, iron deficiency (ferritin <100 ng/mL or ferritin 100–300 ng/mL with a transferrin saturation <20%), and documented heart failure hospitalization or elevated N-terminal pro-brain natriuretic peptide. The primary endpoint of the study was a hierarchical composite of death and heart failure hospitalization at 12 months and change from baseline to 6 months in the 6-minute walk test distance. About the meta-analysis The meta-analysis Impact of ferric carboxymaltose on heart failure-related clinical outcomes in patients with heart failure and iron deficiency: an individual participant data meta-analysis represents the largest pooled analysis to examine the effects of ferric carboxymaltose on clinical outcomes (hospitalizations and mortality) and the first to include the results of the HEART-FID trial. Patient-level data from the three randomized, placebo-controlled ferric carboxymaltose trials CONFIRM-HF, AFFIRM-AHF and HEART-FID with a total of 4'501 adults with HF and iron deficiency with ≥52 weeks follow-up were analysed. The co-primary efficacy endpoints were composite of total/recurrent cardiovascular hospitalizations and cardiovascular death and composite of total HF hospitalizations and cardiovascular death. Both endpoints were examined through 52 weeks of follow-up and based on events adjudicated independently by blinded events committees. Key secondary endpoints included individual components of the composite endpoints.
