Nippon Steel to Invest $6 Billion to Cut Carbon Emissions
Nippon Steel 5401 0.68%increase; green up pointing triangle plans to invest $6 billion to increase production of steel using electric arc furnaces in a bid to reduce carbon emissions.
The Japanese steelmaker said Friday that it would invest 868.7 billion yen, equivalent to $6.02 billion, to establish three electric furnaces in Japan and that it expects the Japanese government to provide up to ¥251.4 billion in support.
Nippon Steel said the investment will increase production capacity by about 2.9 million tons a year, with operations scheduled to commence by the fiscal year starting April 2029.
The company said the conversion to electric arc furnaces from blast furnaces for steelmaking will significantly reduce CO2 emissions.
Electric arc furnaces melt steel scrap to make new steel products, while in a conventional blast furnace, coke made from coal is used for smelting iron ore.
The conversion to electric arc furnaces, though, will require substantial capital investment and lead to higher costs of raw materials and electricity, the company said.
Nippon Steel recently received conditional approval from President Trump to take control of U.S. Steel under what he described as a partnership.
Trump's announcement last week signaled that the Tokyo-based company could eventually enter the American steel market and make the big investments envisioned when it reached a $14.1 billion deal to take over U.S. Steel.

ENHERTU® Reduced the Risk of Death by 30% Versus Ramucirumab Plus Paclitaxel as a Second-Line Therapy in Patients with HER2 Positive Unresectable or Metastatic Gastric Cancer in DESTINY-Gastric04 Phase 3 Trial
Daiichi Sankyo and AstraZeneca's ENHERTU demonstrated a median overall survival of 14.7 months Results reinforce second-line use of ENHERTU globally in this setting TOKYO & BASKING RIDGE, N.J., May 31, 2025--(BUSINESS WIRE)--Positive results from the DESTINY-Gastric04 phase 3 trial showed ENHERTU® (trastuzumab deruxtecan) demonstrated a statistically significant and clinically meaningful improvement in overall survival (OS) compared to ramucirumab plus paclitaxel in patients with second-line HER2 positive (IHC 3+ or IHC 2+/ISH+) unresectable and/or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma. Results will be presented today as a late-breaking oral presentation (LBA #4002) at the 2025 American Society of Clinical Oncology (#ASCO25) Annual Meeting and simultaneously published in The New England Journal of Medicine. ENHERTU is a specifically engineered HER2 directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo (TSE: 4568) and being jointly developed and commercialized by Daiichi Sankyo and AstraZeneca (LSE/STO/Nasdaq: AZN). In the primary endpoint analysis of OS, ENHERTU reduced the risk of death by 30% versus ramucirumab plus paclitaxel (hazard ratio [HR]: 0.70; confidence interval [CI]: 0.55-0.90; p=0.0044). Median OS was 14.7 months with ENHERTU (n=246) versus 11.4 months with ramucirumab plus paclitaxel (n=248). In the secondary endpoint analysis of progression-free survival (PFS), ENHERTU demonstrated a 26% reduction in the risk of disease progression or death versus ramucirumab plus paclitaxel (HR: 0.74; 95% CI: 0.59-0.92; p=0.0074) as assessed by investigator. Median PFS was 6.7 months with ENHERTU versus 5.6 months with ramucirumab plus paclitaxel. A confirmed objective response rate (ORR) of 44.3% (95% CI: 37.8-50.9) was seen in patients treated with ENHERTU with seven complete responses (CR) and 97 partial responses (PR) versus an ORR of 29.1% (95% CI: 23.4-35.3) with three CRs and 66 PRs in the ramucirumab plus paclitaxel arm (p=0.0006). Median duration of response (DOR) was 7.4 months (95% CI: 5.7-10.1) in the ENHERTU arm and 5.3 months (95% CI: 4.1-5.7) in the ramucirumab plus paclitaxel arm. Disease control rate (DCR) was 91.9% (95% CI: 87.7-95.1) with ENHERTU versus 75.9% (95% CI: 70.0-81.2) with ramucirumab plus paclitaxel. Improvements in OS and PFS with ENHERTU were consistent across subgroups. "Gastric cancer is particularly challenging to treat, especially in the advanced stages where the five-year survival rate remains low," said Kohei Shitara, MD, Chief, Department of Gastrointestinal Oncology, National Cancer Center Hospital East, Chiba, Japan and lead investigator in the DESTINY-Gastric04 trial. "The superior overall survival demonstrated in DESTINY-Gastric04 confirms that ENHERTU could become the global standard of care in the second-line metastatic setting of HER2 positive gastric cancer or gastroesophageal junction cancer." The safety profile of ENHERTU in DESTINY-Gastric04 was consistent with previous gastric cancer clinical trials with no new safety concerns identified. The most common grade 3 or higher treatment related adverse events occurring in patients treated with ENHERTU were neutropenia (28.7%), anemia (13.9%), thrombocytopenia (8.6%), leukopenia (7.4%) and fatigue (7.0%). Interstitial lung disease (ILD) or pneumonitis occurred in 13.9% of patients treated with ENHERTU and 1.3% treated in the ramucirumab plus paclitaxel arm. In the ENHERTU arm, the majority of ILD or pneumonitis events were low grade (grade 1 [n=7; 2.9%] or grade 2 [n=26; 10.7%]) except for one grade 3 ILD event (0.4%) as determined by an independent adjudication committee. In the ramucirumab plus paclitaxel arm, there were two grade 3 (0.9%) and one grade 5 (0.4%) ILD events. "ENHERTU continues to deliver impressive results with these new data from DESTINY-Gastric04, which represent the first time a HER2 directed medicine has demonstrated a survival benefit in a randomized phase 3 trial in the second-line HER2 positive metastatic gastric cancer setting," said Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo. "Similar to our strategy in other tumor types, we continue to pursue the development of ENHERTU in earlier stages of gastric cancer and have recently initiated phase 3 trials evaluating ENHERTU as part of a combination regimen as a first-line treatment in patients HER2 positive metastatic disease." "Patients with HER2 positive metastatic gastric cancer who experience progression after first-line treatment have historically faced poor outcomes," said Cristian Massacesi, MD, Chief Medical Officer and Oncology Chief Development Officer, AstraZeneca. "These results showed that ENHERTU reduced the risk of death by nearly one-third in patients with previously treated HER2 positive metastatic gastric cancer, reinforcing the benefit of ENHERTU in this setting." ENHERTU is currently approved in more than 70 countries in the second-line or third-line metastatic setting of HER2 positive gastric cancer based on DESTINY-Gastric01, a randomized phase 2 trial, and DESTINY-Gastric02 and DESTINY-Gastric06, two single-arm phase 2 trials. Daiichi Sankyo and AstraZeneca are currently evaluating ENHERTU in the first-line metastatic setting through the DESTINY-Gastric05 and ARETEMIDE-Gastric01 phase 3 trials. The majority of patients in the DESTINY-Gastric04 trial had received no prior treatment with an immune checkpoint inhibitor (84.1% in the ENHERTU arm and 84.7% in the ramucirumab plus paclitaxel arm) and had two or more metastatic sites (70.3% in the ENHERTU arm and 69.8% in the ramucirumab plus paclitaxel arm). Median duration of follow-up was 16.8 months in the ENHERTU arm and 14.4 months in the ramucirumab plus paclitaxel arm. Median treatment duration was 5.4 months (range: 0.7-30.3) with ENHERTU and 4.6 months (range: 0.9-34.9) with ramucirumab plus paclitaxel. Of the patients that discontinued treatment from the ramucirumab plus paclitaxel arm, 52 (21.0%) proceeded to receive ENHERTU and 12 (4.8%) disitamab vedotin post-trial. As of the data cut-off of October 24, 2024, 18.9% of patients receiving ENHERTU and 18.5% receiving ramucirumab plus paclitaxel remained on study treatment.

The primary endpoint is OS. Secondary endpoints include investigator-assessed progression-free survival, objective response rate, duration of response, disease control rate and safety. In March 2025, an Independent Data Monitoring Committee recommended unblinding DESTINY-Gastric04 based on the superior efficacy of ENHERTU seen at a planned interim analysis. DESTINY-Gastric04 enrolled 494 patients in Asia, Europe and South America. For more information about the trial, visit About HER2 Positive Gastric CancerGastric (stomach) cancer is the fifth most common cancer worldwide and the fifth leading cause of cancer-related death.1 Approximately one million cases of gastric cancer were diagnosed in 2022.1 Gastric cancer is associated with a poor prognosis, particularly in advanced stages of the disease where the five-year survival rate is 5% to 10%.2 HER2 is a tyrosine kinase receptor growth-promoting protein expressed on the surface of many types of tumors, including gastric cancer.3 Approximately one in five gastric cancers are considered HER2 positive.3,4 Prior to the results of the DESTINY-Gastric04 trial of ENHERTU, no other HER2 directed medicine has demonstrated a survival benefit in the second-line metastatic setting in a randomized clinical trial.5 About ENHERTUENHERTU (trastuzumab deruxtecan; fam-trastuzumab deruxtecan-nxki in the U.S. only) is a HER2 directed ADC. Designed using Daiichi Sankyo's proprietary DXd ADC Technology, ENHERTU is the lead ADC in the oncology portfolio of Daiichi Sankyo and the most advanced program in AstraZeneca's ADC scientific platform. ENHERTU consists of a HER2 monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers.

WARNING: INTERSTITIAL LUNG DISEASE and EMBRYO-FETAL TOXICITY Interstitial lung disease (ILD) and pneumonitis, including fatal cases, have been reported with ENHERTU. Monitor for and promptly investigate signs and symptoms including cough, dyspnea, fever, and other new or worsening respiratory symptoms. Permanently discontinue ENHERTU in all patients with Grade 2 or higher ILD/pneumonitis. Advise patients of the risk and to immediately report symptoms. Exposure to ENHERTU during pregnancy can cause embryo-fetal harm. Advise patients of these risks and the need for effective contraception. ContraindicationsNone. Warnings and PrecautionsInterstitial Lung Disease / PneumonitisSevere, life-threatening, or fatal interstitial lung disease (ILD), including pneumonitis, can occur in patients treated with ENHERTU. A higher incidence of Grade 1 and 2 ILD/pneumonitis has been observed in patients with moderate renal impairment. Advise patients to immediately report cough, dyspnea, fever, and/or any new or worsening respiratory symptoms. Monitor patients for signs and symptoms of ILD. Promptly investigate evidence of ILD. Evaluate patients with suspected ILD by radiographic imaging. Consider consultation with a pulmonologist. For asymptomatic ILD/pneumonitis (Grade 1), interrupt ENHERTU until resolved to Grade 0, then if resolved in ≤28 days from date of onset, maintain dose. If resolved in >28 days from date of onset, reduce dose 1 level. Consider corticosteroid treatment as soon as ILD/pneumonitis is suspected (e.g., ≥0.5 mg/kg/day prednisolone or equivalent). For symptomatic ILD/pneumonitis (Grade 2 or greater), permanently discontinue ENHERTU. Promptly initiate systemic corticosteroid treatment as soon as ILD/pneumonitis is suspected (e.g., ≥1 mg/kg/day prednisolone or equivalent) and continue for at least 14 days followed by gradual taper for at least 4 weeks. HER2-Positive, HER2-Low, and HER2-Ultralow Metastatic Breast Cancer, HER2-Mutant NSCLC, and Solid Tumors (Including IHC 3+) (5.4 mg/kg)In patients with metastatic breast cancer, HER2-mutant NSCLC, and other solid tumors treated with ENHERTU 5.4 mg/kg, ILD occurred in 12% of patients. Median time to first onset was 5.5 months (range: 0.9 to 31.5). Fatal outcomes due to ILD and/or pneumonitis occurred in 0.9% of patients treated with ENHERTU. HER2-Positive Locally Advanced or Metastatic Gastric Cancer (6.4 mg/kg)In patients with locally advanced or metastatic HER2-positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg, ILD occurred in 10% of patients. Median time to first onset was 2.8 months (range: 1.2 to 21). NeutropeniaSevere neutropenia, including febrile neutropenia, can occur in patients treated with ENHERTU. Monitor complete blood counts prior to initiation of ENHERTU and prior to each dose, and as clinically indicated. For Grade 3 neutropenia (Absolute Neutrophil Count [ANC] <1.0 to 0.5 x 109/L), interrupt ENHERTU until resolved to Grade 2 or less, then maintain dose. For Grade 4 neutropenia (ANC <0.5 x 109/L), interrupt ENHERTU until resolved to Grade 2 or less, then reduce dose by 1 level. For febrile neutropenia (ANC <1.0 x 109/L and temperature >38.3° C or a sustained temperature of ≥38° C for more than 1 hour), interrupt ENHERTU until resolved, then reduce dose by 1 level. HER2-Positive, HER2-Low, and HER2-Ultralow Metastatic Breast Cancer, HER2-Mutant NSCLC, and Solid Tumors (Including IHC 3+) (5.4 mg/kg)In patients with metastatic breast cancer, HER2-mutant NSCLC, and other solid tumors treated with ENHERTU 5.4 mg/kg, a decrease in neutrophil count was reported in 65% of patients. Nineteen percent had Grade 3 or 4 decreased neutrophil count. Median time to first onset of decreased neutrophil count was 22 days (range: 2 to 939). Febrile neutropenia was reported in 1.2% of patients. HER2-Positive Locally Advanced or Metastatic Gastric Cancer (6.4 mg/kg)In patients with locally advanced or metastatic HER2-positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg, a decrease in neutrophil count was reported in 72% of patients. Fifty-one percent had Grade 3 or 4 decreased neutrophil count. Median time to first onset of decreased neutrophil count was 16 days (range: 4 to 187). Febrile neutropenia was reported in 4.8% of patients. Left Ventricular DysfunctionPatients treated with ENHERTU may be at increased risk of developing left ventricular dysfunction. Left ventricular ejection fraction (LVEF) decrease has been observed with anti-HER2 therapies, including ENHERTU. Assess LVEF prior to initiation of ENHERTU and at regular intervals during treatment as clinically indicated. Manage LVEF decrease through treatment interruption. When LVEF is >45% and absolute decrease from baseline is 10-20%, continue treatment with ENHERTU. When LVEF is 40-45% and absolute decrease from baseline is 20%, interrupt ENHERTU and repeat LVEF assessment within 3 weeks. If LVEF of 20% is confirmed, permanently discontinue ENHERTU. Permanently discontinue ENHERTU in patients with symptomatic congestive heart failure. Treatment with ENHERTU has not been studied in patients with a history of clinically significant cardiac disease or LVEF <50% prior to initiation of treatment. HER2-Positive, HER2-Low, and HER2-Ultralow Metastatic Breast Cancer, HER2-Mutant NSCLC, and Solid Tumors (Including IHC 3+) (5.4 mg/kg)In patients with metastatic breast cancer, HER2-mutant NSCLC, and other solid tumors treated with ENHERTU 5.4 mg/kg, LVEF decrease was reported in 4.6% of patients, of which 0.6% were Grade 3 or 4. HER2-Positive Locally Advanced or Metastatic Gastric Cancer (6.4 mg/kg)In patients with locally advanced or metastatic HER2-positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg, no clinical adverse events of heart failure were reported; however, on echocardiography, 8% were found to have asymptomatic Grade 2 decrease in LVEF. Embryo-Fetal ToxicityENHERTU can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risks to a fetus. Verify the pregnancy status of females of reproductive potential prior to the initiation of ENHERTU. Advise females of reproductive potential to use effective contraception during treatment and for 7 months after the last dose of ENHERTU. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with ENHERTU and for 4 months after the last dose of ENHERTU. Additional Dose ModificationsThrombocytopeniaFor Grade 3 thrombocytopenia (platelets <50 to 25 x 109/L) interrupt ENHERTU until resolved to Grade 1 or less, then maintain dose. For Grade 4 thrombocytopenia (platelets <25 x 109/L) interrupt ENHERTU until resolved to Grade 1 or less, then reduce dose by 1 level.

Use in Specific Populations Pregnancy: ENHERTU can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risks to a fetus. There are clinical considerations if ENHERTU is used in pregnant women, or if a patient becomes pregnant within 7 months after the last dose of ENHERTU. Lactation: There are no data regarding the presence of ENHERTU in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with ENHERTU and for 7 months after the last dose. Females and Males of Reproductive Potential: Pregnancy testing: Verify pregnancy status of females of reproductive potential prior to initiation of ENHERTU. Contraception: Females: ENHERTU can cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential to use effective contraception during treatment with ENHERTU and for 7 months after the last dose. Males: Advise male patients with female partners of reproductive potential to use effective contraception during treatment with ENHERTU and for 4 months after the last dose. Infertility: ENHERTU may impair male reproductive function and fertility. Pediatric Use: Safety and effectiveness of ENHERTU have not been established in pediatric patients. Geriatric Use: Of the 1741 patients with HER2-positive, HER2-low, or HER2-ultralow breast cancer treated with ENHERTU 5.4 mg/kg, 24% were ≥65 years and 4.9% were ≥75 years. No overall differences in efficacy within clinical studies were observed between patients ≥65 years of age compared to younger patients. There was a higher incidence of Grade 3-4 adverse reactions observed in patients aged ≥65 years (61%) as compared to younger patients (52%). Of the 101 patients with HER2-mutant unresectable or metastatic NSCLC treated with ENHERTU 5.4 mg/kg, 40% were ≥65 years and 8% were ≥75 years. No overall differences in efficacy or safety were observed between patients ≥65 years of age compared to younger patients. Of the 125 patients with HER2-positive locally advanced or metastatic gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg in DESTINY-Gastric01, 56% were ≥65 years and 14% were ≥75 years. No overall differences in efficacy or safety were observed between patients ≥65 years of age compared to younger patients. Of the 192 patients with HER2-positive (IHC 3+) unresectable or metastatic solid tumors treated with ENHERTU 5.4 mg/kg in DESTINY-PanTumor02, DESTINY-Lung01, or DESTINY-CRC02, 39% were ≥65 years and 9% were ≥75 years. No overall differences in efficacy or safety were observed between patients ≥65 years of age compared to younger patients. Renal Impairment: A higher incidence of Grade 1 and 2 ILD/pneumonitis has been observed in patients with moderate renal impairment. Monitor patients with moderate renal impairment more frequently. The recommended dosage of ENHERTU has not been established for patients with severe renal impairment (CLcr <30 mL/min). Hepatic Impairment: In patients with moderate hepatic impairment, due to potentially increased exposure, closely monitor for increased toxicities related to the topoisomerase inhibitor, DXd. The recommended dosage of ENHERTU has not been established for patients with severe hepatic impairment (total bilirubin >3 times ULN and any AST).

Trump says he wasn't aware of Musk reportedly using drugs during the 2024 campaign
President Donald Trump said he is not aware of Elon Musk regularly using drugs, responding to a media report on the billionaires' alleged drug use during the 2024 presidential campaign. The New York Times, citing unnamed sources, reported that Musk frequently used drugs such as ketamine, ecstasy and psychedelic mushrooms while campaigning with Trump in 2024. The paper said it was unclear whether Musk used drugs while working for Trump in the Department of Government Efficiency. Trump spoke to reporters May 30 after returning from a rally in Pennsylvania. He denied any knowledge of drug use by Musk and called him "fantastic." Asked if he was troubled by the report, Trump said: "I'm not troubled by anything with Elon." A reporter tried to ask Musk during an Oval Office event May 30 about his alleged drug use during the 2024 campaign. But Musk dodged the question and criticized the New York Times' reporting on Russian interference in the 2016 election. "Let's move on," Musk said, standing behind the president at the Resolute Desk. More: Musk leaves D.C. with black eye: 5 takeaways from Oval Office sendoff with Trump Musk is the CEO of car maker Tesla and rocket company SpaceX, and he owns social-media platform X. He acknowledged in March 2024 that he used prescription ketamine to combat bouts of depression. He worried corporate executives by smoking marijuana during a podcast in 2018.
