Background:
Recombinant human interleukin-2 (rhIL-2, aldesleukin) is Food and Drug Administration approved for the treatment of metastatic melanoma and renal cell carcinoma and has achieved durable response in a subset of patients. However, its utility as an immunotherapeutic drug is limited by undesirable activation of immune suppressive regulatory T cells (Tregs) and a short half-life requiring frequent high dose administration, leading to unacceptable toxicities. We have engineered MDNA11, a long-acting IL-2 superkine, to overcome these limitations by (1) modifying receptor selectivity in favor of anti-cancer immune cells to increase therapeutic efficacy and (2) fusion to human albumin to extend the pharmacokinetic (PK) profile, circumventing the need for frequent dosing.
Methods:
MDNA11 was evaluated using in vitro and in vivo studies including: binding analyses to measure receptor affinity, IL-2 pathway signaling, PK studies in mice, and efficacy studies in syngeneic tumor models as single agent and in combination with immune checkpoint inhibitors. Finally, the safety and pharmacodynamic profile of MDNA11 was assessed in non-human primate (NHP).
Results:
Binding studies with MDNA11 demonstrated increased affinity for IL-2Rβ (CD122) and no binding to IL-2Rα (CD25). As a result, MDNA11 exhibits reduced/limited Treg stimulation while triggering an enhanced activation of natural killer and naïve CD8 T cells compared with rhIL-2. When administered to animals with pre-established tumors, MDNA11 controlled tumor growth in a monotherapy setting and in combination with anti-PD1 or anti-CTLA4 to induce durable tumor clearance with a once weekly dosing regimen. In a NHP model, MDNA11 was well tolerated while triggering durable and potent immune responses including expansion of lymphocytes without significant effect on Tregs and eosinophils, the latter been linked to an increased risk of vascular leak syndrome.
Conclusion:
MDNA11 is a next generation long-acting IL-2 immunotherapeutic with a highly favorable pharmacodynamic profile that translates to a strong therapeutic efficacy in preclinical tumor models and a strong and durable immune response in NHP.

药明康德内容团队整理
ELA026：公布1b期临床试验的新数据
Electra Therapeutics公司公布了其单克隆抗体疗法ELA026用于治疗继发性噬血细胞性淋巴组织细胞增生症的1b期研究结果。sHLH是一种罕见的、危及生命的高炎症性疾病，目前尚无批准的治疗方法。它可以由癌症、感染、自身免疫性疾病或免疫疗法引发。sHLH与严重的炎症反应有关，患者需要立即干预。如果不进行治疗，患者可能会出现多器官衰竭和死亡。sHLH与病程早期的高死亡率相关，使用可用疗法的恶性肿瘤相关HLH（mHLH）患者在两个月时的死亡率约为50%。ELA026靶向髓系细胞和T淋巴细胞表面的SIRP-α/β1/γ，髓系细胞和T淋巴细胞是诱发sHLH细胞因子风暴和高炎症反应的主要病理免疫细胞。以SIRP为靶点选择性地清除致病性免疫细胞具有在免疫学、炎症和癌症领域广泛应用的潜力。
此次公布的研究结果表明，对于mHLH患者，在接受ELA026作为一线治疗的患者中，第4周时的ORR为100%（12/12），出院率为100%(11/11)，2个月生存率为92%（11/12）。安全性方面，ELA026的耐受性良好，不良事件可控。
ARO-CFB：公布1/2a期临床试验的中期数据
Arrowhead Pharmaceuticals公司公布了其靶向补体因子B（CFB）的在研RNAi药物ARO-CFB用于治疗补体介导疾病的1/2a期临床研究的中期结果。ARO-CFB旨在减少肝脏中CFB的表达，CFB在放大补体替代通路活化过程中起着重要的调节作用。ARO-CFB正被开发为补体介导的肾脏疾病的潜在治疗药物，如免疫球蛋白A肾病（IgAN）。此外，ARO-CFB还有望用于涉及补体激活的非肾脏疾病的临床治疗。
截至2024年11月15日的数据，ARO-CFB在正常健康受试者中实现了剂量依赖性的循环CFB蛋白水平降低，平均达90%，且持续时间超过3个月。此外，无论是单次还是多次给药，ARO-CFB几乎完全抑制了替代通路的活性。截至目前，ARO-CFB总体耐受性良好，安全性数据支持进一步的临床开发。
Navenibart（STAR-0215）：公布1b/2期临床试验数据
Astria Therapeutics公司公布了其用于治疗遗传性血管性水肿的血浆激肽释放酶单抗抑制剂navenibart的1b/2期临床试验数据。在该研究中，16名患者被分入三个队列接受STAR-0215皮下给药：队列1的4名患者接受了1剂450 mg剂量；队列2的6名患者先接受了1剂600 mg剂量，并在3个月后又接受了1剂300 mg剂量；队列3的6名患者先接受了1剂600 mg剂量，并在1个月后又接受了1剂600 mg剂量。
此次公布的结果显示，在6个月内给药1次或2次navenibart，3个队列患者的平均每月发作率降低了90%-95%，该结果支持每年仅给药2次或4次。此外，使用navenibart后，中度或严重HAE发作减少了约95%-96%，需要使用急救药物的发作减少了91%-94%。队列2和队列3患者6个月内的无发作率为67%。安全性方面，navenibart总体耐受性良好，无严重不良事件，无停药现象。
IO-202：公布1b期临床试验扩展队列的新数据
Immune-Onc Therapeutics公司公布了其1b期扩展队列的最新数据，该队列评估了其抗LILRB4抗体IO-202联用阿扎胞苷（AZA）治疗慢性粒单核细胞白血病（CMML）患者的疗效和安全性。IO-202是一款潜在"first-in-class"的IgG1抗体，可特异性、高亲和力地与LILRB4结合，并通过抗体依赖性细胞毒性和抗体依赖性细胞吞噬作用消除LILRB4阳性细胞。因此，IO-202是一种在血癌、自身免疫性和炎症性疾病方面具有广阔潜力的靶向疗法。
此次公布的结果显示，根据国际工作组2023缓解标准，在接受IO-202与AZA联合治疗的18名疗效可评估的CMML患者中，ORR为66.7%，完全缓解（CR）率为50%。在LILRB4高表达的CMML患者中，ORR为100%，CR率为83.3%。值得注意的是，过往获批疗法的CR率仅为7-17%。
ISB 2001：公布1期临床试验的新数据
Ichnos Glenmark Innovation公司公布了其三特异性抗体ISB 2001用于治疗复发/难治性多发性骨髓瘤（RRMM）的1期研究的新数据。ISB 2001同时靶向MM细胞上的BCMA和CD38，以及T细胞上的CD3，旨在增加对MM细胞的特异性结合，同时最大限度地减少脱靶效应。
截至2024年10月1日的数据，20名可评估疗效患者的ORR为75%（5/20），CR/严格的CR（sCR）率为20%。在接受活性剂量（0.05 mg/kg和更高剂量）治疗的18例患者中，ORR为83%，CR/sCR率为22%。安全性方面，在每周皮下注射剂量为1.2 mg/kg时未观察到剂量限制性毒性（DLT），大多数是轻度的细胞因子释放综合征（CRS），未报告神经毒性，也没有患者因不良事件而停药。
NX-5948：公布1a/1b期临床试验的新数据
Nurix Therapeutics公司公布了其布鲁顿酪氨酸激酶（BTK）降解剂NX-5948用于治疗复发或难治性慢性淋巴细胞白血病或小淋巴细胞淋巴瘤（CLL/SLL）的1a/1b期临床试验的新数据。NX-5948是一种口服、可穿越血脑屏障的小分子BTK蛋白降解剂。
截至2024年10月10日的数据，首次疾病评估时（治疗后第8周）49名疗效可评估的CLL/SLL患者的客观缓解率为75.5%，该数据在至少进行两次疾病评估（治疗后第16周时）的患者中增加至84.2%。无论患者既往治疗、基线突变、高危分子特征或中枢神经系统（CNS）受累如何，均观察到缓解。13名患者的缓解持续时间超过6个月，5名患者在治疗一年后仍在接受治疗并保持缓解。此外，NX-5948在所有评估的剂量中均具有良好的耐受性。
Enzomenib（DSP-5336）：公布1/2期临床试验的新数据
Sumitomo Pharma America公司公布了其在研口服小分子enzomenib用于治疗复发/难治性急性白血病的1/2期临床试验的新数据。Enzomenib可抑制menin与MLL蛋白的相互作用，并能降低白血病相关基因HOXA9和MEIS1的表达，增加带有MLL重排和NPM1突变的人类急性白血病细胞系中分化基因CD11b的表达。
此次公布的结果显示，在23例KMT2A重排患者中，客观缓解率为65.2%，达到CR加部分血液学恢复的完全缓解（CRh）的患者比例为30.4%。在接受300 mg每日两次（BID）治疗的15名KMT2A重排患者中，客观缓解率为73.3%，达到CR加CRh的比例为40%。在接受200 mg BID或300 mg BID治疗的17名NPM1突变患者中，客观缓解率为58.8%，达到CR加CRh的比例为47.1%。Enzomenib的耐受性良好，药物相关不良事件的总体发生率较低，没有报告DLT。10.7%的患者患上了分化综合征，但未导致患者死亡，也不需要永久停用enzomenib。
Evorpacept：公布1b/2期联合治疗试验数据
ALX Oncology公司公布了其CD47抑制剂evorpacept联用HER2靶向双特异性抗体zanidatamab治疗此前接受过大量治疗的HER2阳性和HER2低表达转移性乳腺癌患者的1b/2期临床试验数据。Evorpacept是一种下一代CD47阻断疗法，它将高亲和性CD47结合结构域与经特殊处理的Fc结构域相结合，因此无法激活Fc受体，有望降低CD47靶向抗体因激活Fc受体可能产生的毒副作用。此外，与其它抗CD47抗体相比，evorpacept的分子量更小，更容易渗透到实体瘤中，从而提高疗效。
此次公布的结果显示，evorpacept联用zanidatamab对经中央实验室评估确认为HER2阳性的患者（n=9）显示出最强的抗肿瘤活性。这些患者经确认的客观缓解率为55.6%，中位无进展生存期（PFS）为7.4个月。总体而言，队列1（HER2阳性的转移性乳腺癌患者）患者（n=21）的经确认的客观缓解率为33.3%，中位PFS为3.6个月，中位缓解持续时间（DOR）尚未达到。在队列2（HER2低表达的转移性乳腺癌患者）的患者（n=15）中也观察到了一定的缓解，经确认的客观缓解率为20.0%，中位PFS为1.9个月，中位DOR为5.5个月。
MDNA11：公布1/2期临床试验的新数据
Medicenna Therapeutics公司公布了正在进行的1/2期ABILITY-1研究的最新临床数据，该研究旨在评估其下一代长效IL-2超级激动剂MDNA11单药或联用PD-1抑制剂帕博利珠单抗治疗晚期实体瘤的疗效和安全性。MDNA11是一种通过静脉注射给药的长效“增强β而非α”的IL-2超级细胞因子（IL-2 Superkine），它能够优先激活负责杀伤癌细胞的免疫效应细胞（CD8阳性T细胞和自然杀伤细胞，即NK细胞），同时最小化或不刺激具有免疫抑制作用的调节性T细胞（Tregs）。
此次公布的结果显示，MDNA11单药治疗和联用帕博利珠单抗的疾病控制率（DCR）分别为55%（1例CR、4例部分缓解和6例疾病稳定）和78%（1例CR、1例部分缓解和5例疾病稳定）。1名70岁的晚期化疗难治性肛门癌患者在接受MDNA11联用帕博利珠单抗治疗时，在8周内达到了CR。单药治疗组中两名免疫检查点抑制剂耐药患者的所有肿瘤完全消失，1名获得CR的黑色素瘤患者在第63周时依然没有复发，1名微卫星不稳定性高（MSI-H）的胰腺癌患者在肝脏中实现了靶病灶和非靶转移灶的完全消除，在研究期间实现了20个月的持久缓解，并已持续停止抗癌治疗达11个月。
VGA039：公布1期临床试验的中期数据
Star Therapeutics公司公布了其在研单克隆抗体VGA039用于治疗血管性血友病（Von Willebrand Disease，VWD）的1期单剂量递增（SAD）研究的中期数据。VGA039靶向蛋白质S，旨在恢复血液凝固的平衡，有望作为一种适用于多种出血性疾病的通用止血疗法。
此次公布的数据显示，在3名高年出血率（ABR）VWD患者中，皮下注射VGA039与ABR的显著降低相关，单次注射使患者的ABR降低了75%-88%，且治疗浓度保持了约4周。该降幅与已获批准的VWD预防疗法在临床试验中观察到的降幅一致，但这些疗法需要每周进行多次静脉注射。在安全性可评估的7名患者中，VGA039安全且耐受性良好，未观察到注射部位反应。

Single-agent MDNA11 was more effective than a combination of immune checkpoint inhibitors (anti-mPD1 and anti-mCTLA4) in preventing metastasis and achieving long-term survival in an aggressive mouse model of triple negative breast cancer (TNBC) Mice treated with MDNA11 prior to surgery were able to mount powerful immune and memory response to subsequent tumor rechallenges, demonstrating potential to prevent new tumor growth TORONTO and HOUSTON, Dec. 13, 2024 (GLOBE NEWSWIRE) -- Medicenna Therapeutics Corp. (“Medicenna” or the “Company”) (TSX: MDNA, OTCQX: MDNAF), a clinical-stage immunotherapy company focused on the development of Superkines, announced that new preclinical data on MDNA11 was presented at the 2024 San Antonio Breast Cancer Symposium (SABCS), the world’s largest breast cancer conference, taking place from December 10-13, 2024, in San Antonio, Texas. Metastasis is the leading cause of cancer-related deaths worldwide. 1 in 8 women will be diagnosed with breast cancer in the US and 1 in 3 of those will become metastatic resulting in approximately 42,000 breast cancer deaths every year. Of those deaths, it is estimated that 97-99% of those will be from metastatic breast cancer.1 Among breast cancer subtypes, triple-negative breast cancer (TNBC) is particularly aggressive, spreading more rapidly and representing a significant unmet medical need. Neoadjuvant immunotherapy offers a promising treatment strategy in which patients with advanced but resectable cancer receive immunotherapy before surgery. This approach aims to shrink tumors, making them easier to remove, delay or prevent metastasis, while also targeting cancerous tissue that may not yet be detectable. Additionally, immunotherapy can prime the immune system against tumor antigens, promoting the development of long-lasting anti-cancer T cells. These T cells may help protect against residual tumor cells that could re-emerge and drive metastatic disease. The presentation at 2024 SABCS highlighted the potential of MDNA11, a long-acting ‘β-enhanced not-α’ IL-2 Superkine, to improve treatment outcomes when administered prior to surgery. New findings demonstrated that a single low dose of MDNA11 as a neoadjuvant therapy significantly prevented metastasis, extended survival, and enabled a memory immune response that protects against tumor rechallenges in a TNBC model. “We are impressed by MDNA11’s remarkable capability, in the on-going ABILITY-1 clinical trial, to durably control cancer in patients with advanced late-stage metastatic disease in immunotherapy resistant tumors. This naturally encourages us to evaluate the potential of MDNA11 to tackle cancer head-on at the earlier stages of the disease and reverse cancer from a death sentence to a chronic manageable condition,” said Fahar Merchant, PhD, President and CEO of Medicenna. “Our findings show that MDNA11 alone not only prevents metastasis in an aggressive preclinical breast cancer model when administered as a single pre-treatment prior to surgery, but also delivers superior long-term survival by preventing metastasis when compared to combinations of the leading checkpoint inhibitors, such as anti-CTLA4 and anti-PD-1. These data illustrate MDNA11’s potential to redefine traditional immunotherapy by attacking cancer at its earliest stages and efficiently leverage the patient’s healthier immune status to dramatically improve patient outcomes.” Key findings from presentation of MDNA11 pre-treatment prior to surgery in the aggressive TNBC model included: Metastasis Prevention: A single dose of neoadjuvant MDNA11 prevented the spread of tumors, with vast majority of treated mice (7/8 at high-dose of 5 mg MDNA11/kg and 6/7 at low-dose of 2 mg MDNA11/kg) surviving to study end (>4 months) without signs of metastasis despite tumor rechallenges. By contrast, all mice in the control group developed multiple metastasis and died within ~2 months even after tumor resection surgery.Superior to Checkpoint Inhibitors: MDNA11 alone, even at the lower dose, was more effective than a combination of immune checkpoint inhibitors (anti-mPD1 and anti-mCTLA4) in preventing metastasis and achieving long-term survival.Memory Response Against Tumor Rechallenge: Mice treated with MDNA11 were able to mount strong immune response to subsequent tumor rechallenges by engaging tumor antigen-specific T cells, demonstrating protection against new tumor growth.Immune Cell Activation: MDNA11 promoted the infiltration of CD8+ T cells with potent tumor-killing capacity (GrzB+) into the tumor microenvironment (TME) with no impact on immune-suppressive Treg cells, driving a potent and lasting immune response. A copy of the presentation has been posted on the “Scientific Presentations” page of Medicenna’s website. About MDNA11 MDNA11 is an intravenously administered, long-acting, ‘beta-enhanced not-alpha’ IL-2 Superkine specifically engineered to overcome the shortcomings of aldesleukin and other next generation IL-2 variants by preferentially activating immune effector cells (CD8+ T and NK cells) responsible for killing cancer cells, with minimal or no stimulation of immunosuppressive Tregs. These unique proprietary features of the IL-2 Superkine have been achieved by incorporating seven specific mutations and genetically fusing it to a recombinant human albumin scaffold to improve the pharmacokinetic (PK) profile and pharmacological activity of MDNA11 due to albumin’s natural propensity to accumulate in highly vascularized sites, in particular tumor and tumor draining lymph nodes. MDNA11 is currently being evaluated in the Phase 1/2 ABILITY-1 study as both monotherapy and in combination with pembrolizumab. About Medicenna Therapeutics Medicenna is a clinical-stage immunotherapy company focused on developing novel, highly selective versions of IL-2, IL-4 and IL-13 Superkines and first-in-class Empowered Superkines. Medicenna’s long-acting IL-2 Superkine, MDNA11, is a next-generation IL-2 with superior affinity toward CD122 (IL-2 receptor beta) and no CD25 (IL-2 receptor alpha) binding, thereby preferentially stimulating cancer-killing effector T cells and NK cells. MDNA11 is being evaluated in the Phase 1/2 ABILITY-1 Study (NCT05086692) as a monotherapy and in combination with pembrolizumab. Medicenna’s IL-4 Empowered Superkine, bizaxofusp (formerly MDNA55), has been studied in 5 clinical trials enrolling over 130 patients, including a Phase 2b trial for recurrent GBM, the most common and uniformly fatal form of brain cancer. Bizaxofusp has obtained FastTrack and Orphan Drug status from the FDA and FDA/EMA, respectively. Medicenna’s early-stage high-affinity IL-2β biased IL-2/IL-15 Super-antagonists, from its MDNA209 platform, are being evaluated as potential therapies for autoimmune and graft-versus host diseases. Medicenna’s early-stage BiSKITs™ (Bifunctional SuperKine ImmunoTherapies) and the T-MASK™ (Targeted Metalloprotease Activated SuperKine) programs are designed to enhance the ability of Superkines to treat immunologically “cold” tumors.

Additional monotherapy and combination clinical data from the ABILITY-1 study will be presented at medical conferences in Q1 and Q2 of 2025 TORONTO and HOUSTON, Dec. 05, 2024 (GLOBE NEWSWIRE) -- Medicenna Therapeutics Corp. (“Medicenna” or the “Company”) (TSX: MDNA, OTCQX: MDNAF), a clinical-stage immunotherapy company focused on the development of Superkines, announced that updated clinical data from the ongoing Phase 1/2 ABILITY-1 study were presented today at the 2024 Immunotherapy Bridge held in Naples, Italy. The oral presentation by Dr Arash Yavari, MB BS, DPhil, included new data highlighting the first complete response (CR) in the combination dose escalation phase of the study in a 70-year-old patient with advanced anal squamous cell carcinoma (anal SCC), in addition to follow up safety and efficacy results from the monotherapy and combination arms of the ABILITY-1 study. The anal SCC patient previously progressed on two prior lines of treatment comprising of chemotherapy combination and chemo-radiation treatments. The patient achieved a 100% reduction of all measurable target and non-target lesions by Week 8, highlighting MDNA11’s potential to enhance checkpoint inhibitor efficacy in advanced solid tumor types traditionally considered less sensitive to immunotherapy. “These remarkable results from our monotherapy and early data from the combination dose escalation highlights the transformative potential of MDNA11 as a combination therapy with checkpoint inhibitors like KEYTRUDA®, while demonstrating an acceptable safety profile as dose escalation continues,” said Fahar Merchant, PhD, President and CEO of Medicenna. “Achieving a complete response in a patient with anal squamous cell carcinoma, a cancer with historically low immunotherapy response rates, demonstrates MDNA11’s ability to reinvigorate the immune system and tackle difficult-to-treat tumors. We look forward to sharing additional clinical data at medical conferences in Q1 and Q2 of 2025 as we advance MDNA11 as a potent and safe immunotherapy to dramatically improve current immunotherapies and deliver life-changing outcomes for patients.” Key findings from the on-going ABILITY-1 study (data cut-off as of November 18th, 2024) include: Safety Profile MDNA11 has a favorable safety profile both as a monotherapy and in combination with KEYTRUDA®. Over 90% of treatment-related adverse events (TRAEs) were Grade 1-2 and transient, with no DLTs or new safety signals observed in combination dose escalation cohorts. MDNA11 at doses of 120 µg /kg (Q3W monotherapy; Q2W and Q3W in combination with Keytruda (400 mg Q6W) are currently being evaluated. Immunodynamics MDNA11 preferentially expands immune effector cells, including activated (CD25+) and “stemness-like” (TCF-1+) CD8+ T cells, which are critical for sustained anti-tumor responses.Robust, dose-dependent lymphocyte expansion in combination with KEYTRUDA®, sustained with repeat MDNA11 dosing. Monotherapy Tumor Response in Immune Checkpoint Inhibitor-Resistant Patients MDNA11 continues to demonstrate encouraging deep and durable single-agent anti-tumor activity among patients who progressed on prior ICI therapy: An objective response rate (ORR) of 30% in the monotherapy dose expansion arm with 3 PRs among 10 patients who had all previously failed ICI therapy and had advanced and/or metastatic melanoma, non-melanoma skin cancer or MSI-H/dMMR tumors. The ORR is 25% from a total of 20 patients when including 10 phase 2 eligible patients from the MDNA11 monotherapy dose escalation arm who received at least 60 µg/kg MDNA11 and were ICI-resistant.Overall, objective responses in ICI-resistant patients include 1 CR and 4 PRs 2 PRs among 3 MSI-H patients (ORR of 66.7%) with both responders having metastatic pancreatic ductal adenocarcinoma (PDAC).1 CR and 2 PRs among 11 patients with cutaneous melanoma (ORR of 27.3%). Complete resolution of all target and non-target lesions in two patients: 1 confirmed CR in a melanoma patient continues on treatment as of week 63.Pancreatic cancer patient (MSI-H) achieved complete resolution of target and non-target metastatic lesions in the liver including a new lesion treated with MDNA11 following a single cycle of radiation, achieved durable response for 20 months during the study and continues to remain off anti-cancer therapy for 11 months. SD in 6 patients for a disease control rate (DCR = CR+PR+SD) of 55% including 3 with duration > 6 months, yielding a clinical benefit rate of 40% (8/20). MDNA11 Combination with KEYTRUDA® Tumor Response The objective of the combination dose escalation/evaluation portion of the ABILITY-1 study is to assess the safety, pharmacokinetics and immunodynamics of MDNA11 at various doses and dosing regimens when combined with KEYTRUDA® (400mg, Q6W), and to determine the recommended dose and schedule for the combination dose expansion portion of the study. Encouraging preliminary signs of anti-tumor activity have been observed with MDNA11 in combination with KEYTRUDA® to date in dose escalation cohorts 1 (60 µg/kg Q2W MDNA11) and 2 (90 µg/kg Q2W MDNA11). Among 9 heavily pre-treated, efficacy-evaluable patients, tumor control was observed in 7 patients for a DCR of 78% including a CR in an anal squamous cell carcinoma patient and PR in a microsatellite-stable (MSS) colorectal cancer patient. CR in a 70-year-old male with anal squamous cell carcinoma Patient progressed on 2 prior lines of chemotherapy (1L capecitabine/mitomycin plus radiation therapy; 2L carboplatin/paclitaxel)CR achieved on first study evaluable imaging scan at Week 8; patient continues on combination treatment Confirmed PR in 52-year-old female with MSS colorectal cancer Patient progressed on 2 prior lines of chemotherapy (1L folinate/fluorouracil/oxaliplatin; 2L capecitabine)Continues on combination treatment as of week 32
