/PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq:

) ('RedHill' or the 'Company'), a specialty biopharmaceutical company, today announced that its partner, the University of Oklahoma (OU), has received $2.9 million in funding from the National Cancer Institute (NCI) to study, in clinical trials, whether RedHill's opaganib[1], given after CAR (chimeric antigen receptor) T-cell therapy, may help immune cells fight cancer more effectively..

专业生物制药公司RedHill（以下简称“RedHill”或“公司”）今日宣布，其合作伙伴俄克拉荷马大学（OU）已获得美国国家癌症研究所（NCI）提供的290万美元资金，用于开展临床试验，研究在CAR（嵌合抗原受体）T细胞疗法之后使用RedHill的opaganib[1]是否有助于免疫细胞更有效地对抗癌症。

The five-year, $2.9 million grant from the NCI is planned to fund two phases of clinical trials. A Phase 1b trial plans to enroll up to 18 patients to evaluate the safety of the treatment combination of CAR T-cell therapy and opaganib and determine the appropriate dosage of opaganib. A subsequent Phase 2 trial plans to enroll up to 21 additional patients to seek preliminary evidence of effectiveness..

美国国家癌症研究所（NCI）提供的为期五年、金额为290万美元的资助，计划用于支持两个阶段的临床试验。一项1b期临床试验计划招募最多18名患者，以评估CAR T细胞疗法与opaganib联合治疗的安全性，并确定opaganib的合适剂量。随后的2期临床试验计划再招募最多21名患者，以寻求初步的有效性证据。

CAR T-cell therapy takes a patient's immune cells, genetically modifies them so they can recognize and attack cancer cells, and then returns them to the patient. In a first for Oklahoma, the CAR T cells will be manufactured on the OU campus rather than being sent to a commercial manufacturer, potentially saving both time and money..

CAR T细胞疗法提取患者的免疫细胞，通过基因改造使其能够识别并攻击癌细胞，然后将这些细胞回输到患者体内。在俄克拉荷马州，此举尚属首次：CAR T细胞将在俄克拉荷马大学校园内制备，而非送往商业制造商处，这有望节省时间和费用。

'We need to find a novel, more effective treatment option for patients with ultra-high-risk multiple myeloma as they continue to have poor outcomes despite current treatments,'

“我们需要为超高危多发性骨髓瘤患者寻找一种新颖且更有效的治疗方案，因为尽管接受当前治疗，他们的预后仍然不佳。”

. 'With 10 years of preclinical studies on CAR T-cell therapy and opaganib, we believe the findings suggest that opaganib may help the modified immune cells remain active and continue attacking myeloma for longer. Opaganib works by blocking a protein called sphingosine kinase-2 (SPHK2), which appears to act as a kind of brake on the immune system's cancer-fighting T cells.

“基于对CAR-T细胞疗法和奥帕加尼布（opaganib）长达10年的临床前研究，我们认为这些发现表明，奥帕加尼布可能有助于修饰后的免疫细胞保持活性，并更持久地持续攻击骨髓瘤细胞。奥帕加尼布通过阻断一种名为鞘氨醇激酶-2（SPHK2）的蛋白质发挥作用，该蛋白似乎对免疫系统抗癌T细胞的功能起到某种抑制作用。”

When SPHK2 was absent or blocked in mice, T cells multiplied more effectively and became better at killing myeloma cells. When combining opaganib with CAR T-cell therapy .

当小鼠体内缺乏或阻断SPHK2时，T细胞更有效地增殖，并增强了杀伤骨髓瘤细胞的能力。将奥帕加尼布与CAR T细胞疗法联合使用时。

in mice, the results were encouraging, with tumor growth controlled for a longer period of time[2]. I am excited to see whether combining CAR T-cell therapy with opaganib can produce longer-lasting responses and improve outcomes for these high-risk patients.'

在小鼠实验中，结果令人鼓舞，肿瘤生长在更长时间内得到了控制[2]。我期待看到CAR T细胞疗法与奥帕加尼布联合使用是否能产生更持久的缓解反应，并改善这些高危患者的预后。

Dr. Mark Levitt, RedHill's Chief Scientific Officer said

RedHill 首席科学官 Mark Levitt 博士表示

: 'Opaganib has shown promise in preclinical studies as a potential combination therapy in a number of oncology and other indications. Prior preclinical and clinical work has shown that through a reduction of cancer cell survival proteins like c-Myc and Mcl-1[3], opaganib can potentially play a role in the treatment of multiple myeloma.

奥帕加尼布在临床前研究中显示出作为多种肿瘤学及其他适应症潜在联合疗法的希望。先前的临床前和临床研究显示，通过降低c-Myc和Mcl-1等癌细胞存活蛋白的水平[3]，奥帕加尼布可能在多发性骨髓瘤的治疗中发挥作用。

We congratulate Dr. Kang and OU on this grant, which has the potential to be an important step to determine through clinical trials, whether these preclinical findings can turn into reality.' .

我们祝贺康博士和俄克拉荷马大学获得此项资助，该资助有望成为通过临床试验确定这些临床前发现能否转化为现实的重要一步。

For patients with ultra-high-risk multiple myeloma, cancer often returns despite treatment, including bone marrow transplantation. CAR T-cell therapy is already an option for some patients whose cancer has returned.

对于超高危多发性骨髓瘤患者，尽管接受了包括骨髓移植在内的治疗，癌症仍常常复发。CAR T细胞疗法已是部分复发患者的可选治疗方案。

The clinical trials will be conducted in partnership with RedHill, which is expected to provide opaganib, and Lentigen Technology, Inc., a Miltenyi Biotec, which developed the CAR construct. Miltenyi Biotec is enabling clinical translation by producing GMP-grade lentiviral vector for CAR T manufacturing on the CliniMACs Prodigy..

临床试验将与RedHill公司（预计提供opaganib）以及Miltenyi Biotec旗下的Lentigen Technology, Inc.（开发了CAR结构）合作开展。Miltenyi Biotec通过在CliniMACS Prodigy系统上生产用于CAR-T制造的GMP级慢病毒载体，推动临床转化。

About Opaganib (ABC294640)

关于奥帕加尼布（ABC294640）

Opaganib is a proprietary first-in-class investigational, orally administered sphingosine kinase-2 (SPHK2) selective inhibitor drug. Potentially broad-acting, it is in development for multiple oncology, viral, inflammatory, metabolic (diabetes and obesity) and additional indications.

Opaganib 是一种专有的、首创类的在研口服选择性鞘氨醇激酶-2（SPHK2）抑制剂药物。该药具有潜在的广谱作用，目前正针对多种肿瘤学、病毒性、炎症性、代谢性（糖尿病和肥胖症）以及其他适应症进行开发。

Opaganib's suggested mechanism of action,

奥帕加尼布的推荐作用机制，

published

已发布

in the journal Drug Design, Development and Therapy, is host-directed and potentially broad-acting and is expected to maintain its effect against emerging viral variants. Opaganib is thought to work through the inhibition of multiple pathways, the induction of autophagy and apoptosis, and disruption of viral replication, through simultaneous inhibition of three sphingolipid-metabolizing enzymes in human cells (SPHK2, DES1 and GCS)..

发表在《药物设计、开发与治疗》期刊上的研究表明，该疗法以宿主为靶点，可能具有广谱活性，并有望对新兴的病毒变异株保持疗效。据认为，Opaganib 通过同时抑制人体细胞中的三种鞘脂代谢酶（SPHK2、DES1 和 GCS），从而抑制多条信号通路、诱导自噬和凋亡，并破坏病毒复制。

Opaganib has received Orphan Drug designation from the FDA for the treatment of neuroblastoma and cholangiocarcinoma.  A Bayer-supported placebo-controlled randomized Phase 2 study is ongoing to evaluate the efficacy of opaganib in combination with Bayer's darolutamide in men with metastatic castrate-resistant prostate cancer (mCRPC), testing the potentially enhancing effect of opaganib in patients with a poor prognosis.

奥帕加尼布已获得美国食品药品监督管理局（FDA）授予的孤儿药资格，用于治疗神经母细胞瘤和胆管癌。目前，一项由拜耳支持的安慰剂对照随机二期临床试验正在进行中，旨在评估奥帕加尼布与拜耳的达罗他胺联合用药在治疗转移性去势抵抗性前列腺癌（mCRPC）男性患者中的疗效，并检验奥帕加尼布对预后不良患者的潜在增强作用。

. Opaganib also has a Phase 1 chemoradiotherapy study protocol ready for FDA-IND submission.

奥帕加尼布还有一项1期放化疗研究的方案已准备就绪，可向美国食品药品监督管理局提交新药临床试验申请（IND）。

Opaganib has demonstrated its safety and tolerability profile in more than 470 participants in multiple clinical studies and expanded access use, including a large global Phase 2/3 study in hospitalized patients with moderate to severe COVID-19, published in
