IL3RA (CD123) is the alpha subunit of the interleukin 3 (IL-3) receptor, which regulates the proliferation, survival, and differentiation of hematopoietic cells. IL3RA is frequently expressed in acute myeloid leukemia (AML) and classical Hodgkin lymphoma (HL), presenting an opportunity to treat AML and HL with an IL3RA-directed antibody–drug conjugate (ADC). Here, we describe BAY-943 (IL3RA-ADC), a novel IL3RA-targeting ADC consisting of a humanized anti-IL3RA antibody conjugated to a potent proprietary kinesin spindle protein inhibitor (KSPi). In vitro, IL3RA-ADC showed potent and selective antiproliferative efficacy in a panel of IL3RA-expressing AML and HL cell lines. In vivo, IL3RA-ADC improved survival and reduced tumor burden in IL3RA-positive human AML cell line-derived (MOLM-13 and MV-4-11) as well as in patient-derived xenograft (PDX) models (AM7577 and AML11655) in mice. Furthermore, IL3RA-ADC induced complete tumor remission in 12 out of 13 mice in an IL3RA-positive HL cell line-derived xenograft model (HDLM-2). IL3RA-ADC was well-tolerated and showed no signs of thrombocytopenia, neutropenia, or liver toxicity in rats, or in cynomolgus monkeys when dosed up to 20 mg/kg. Overall, the preclinical results support the further development of BAY-943 as an innovative approach for the treatment of IL3RA-positive hematologic malignancies.

Vincerx Pharma Reports Third Quarter 2024 Financial Results

Continued enrollment and dose escalation in Phase 1 study of VIP943, a potentially best-in-class anti-CD123 antibody-drug conjugate (ADC); additional data expected by early 2025 Completed Phase 1 dose-escalation studies of small molecule drug-conjugate (SMDC), VIP236, and CDK9 inhibitor, enitociclib, and identified the maximum tolerated dose Expected cash runway into early 2025 PALO ALTO, Calif., Nov. 12, 2024 (GLOBE NEWSWIRE) -- Vincerx Pharma, Inc. (Nasdaq: VINC), a biopharmaceutical company aspiring to address the unmet medical needs of patients with cancer through paradigm-shifting therapeutics, today reported financial results for the third quarter of 2024 and provided an overview of its clinical programs and anticipated milestones. “As we direct our efforts and resources toward our ADC technologies and programs, we are committed to advancing VIP943 based on the encouraging safety, efficacy, and tolerability results observed to date. We look forward to presenting additional data from patients at efficacious dose cohorts by early next year,” said Ahmed Hamdy, M.D., Chief Executive Officer. “Securing the funding necessary to advance our programs remains a priority. Alongside exploring financing options, we remain focused on strategic partnerships, particularly as pharmaceutical companies intensify their search for truly differentiated and transformative technologies.” THIRD QUARTER 2024 CLINICAL PROGRAM HIGHLIGHTS AND ANTICIPATED MILESTONES VIP943 VIP943 is a novel CD123-targeted ADC developed with the Company’s next-generation VersAptx platform.VIP943 has shown promising safety, efficacy, and tolerability in an ongoing Phase 1 dose-escalation study for patients with relapsed/refractory acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and B-cell acute lymphoblastic leukemia (B-ALL) (NCT06034275). In October, the Company reported two complete responses in this Phase 1 study: one out of four patients with relapsed AML in the 1 mg/kg dose cohort achieved complete remission with incomplete hematologic recovery (CRi), and one out of one patient with higher-risk MDS in the 1.3 mg/kg dose cohort achieved complete remission with limited count recovery (CRL).VIP943 has shown effective target engagement and elimination of CD123+ malignant cells, with pharmacodynamic data demonstrating decreases in CD123+ blasts after dosing. Preliminary pharmacokinetic data indicates minimal payload release (≤1% in plasma), signifying a stable linker.Given the favorable safety and tolerability observed for VIP943, the Company continues dose escalation to assess potential for additional efficacy. Enrollment in the once-weekly and twice-weekly (as an induction therapy) dosing schedules is ongoing.Vincerx expects to share additional Phase 1 study data for VIP943 by early 2025. Enitociclib Enitociclib is a highly selective CDK9 inhibitor designed to block the activation of RNA polymerase II, leading to inhibition of oncogenes, including MYC and MCL1.Enitociclib is currently in a Phase 1 dose-escalation study (NTC05371054) evaluating the combination of enitociclib, venetoclax, and prednisone in diffuse large B-cell lymphoma (DLBCL) and peripheral T-cell lymphoma (PTCL). This study is being conducted in collaboration with the National Institutes of Health (NIH). As of September 2024, the study reported four partial responses (PRs) in seven patients (57% overall response rate), including one patient with double hit lymphoma (DH-DLBCL) and three patients with PTCL.Enitociclib has successfully completed its Phase 1 dose-escalation study as a monotherapy (NCT02635672), enrolling 63 patients across dose-escalation and expansion cohorts. The treatment demonstrated a favorable safety profile, dose-proportional pharmacokinetics, and on-target pharmacodynamic activity. Clinical benefits included durable complete metabolic remissions in two patients with DH-DLBCL, lasting 3.7 and 2.3 years, with both remissions continuing more than two years after treatment cessation. In addition, a transformed follicular (tFL) patient achieved a PR with a 63% tumor reduction after nearly two years, a meaningful outcome given the historically poor prognosis of tFL. Furthermore, 13 patients with solid tumors achieved stable disease as their best response, including five ovarian cancer patients—indicating a promising path for future combination studies in this indication.The Company is actively focused on finding a strategic partner to continue the development of this asset. VIP236 VIP236 is a αVβ3 SMDC conjugated to an optimized camptothecin (CPT) payload developed with the Company’s VersAptx platform.VIP236 has completed its Phase 1 dose-escalation study (NCT05712889), identifying the maximum tolerated dose that could be utilized in future studies. As reported in October, a total of 29 patients were enrolled in the Phase 1 study, resulting in a 45% disease control rate. The drug demonstrated a favorable safety profile, distinguishing itself from other CPTs by showing no instances of common dose-limiting side effects such as life-threatening diarrhea, severe stomatitis/mucositis, or interstitial lung disease.The Company intends to identify a partner to champion VIP236 through further development. THIRD QUARTER 2024 FINANCIAL RESULTS Vincerx had approximately $10.1 million in cash, cash equivalents, and marketable securities as of September 30, 2024, as compared to approximately $16.3 million as of June 30, 2024. Based on its current business plans and assumptions, Vincerx believes its available capital will be sufficient to meet its operating requirements into early 2025.Research and development expenses for the third quarter ended September 30, 2024, were approximately $3.9 million, as compared to approximately $6.1 million for the same period in 2023. This decrease is primarily the result of decreases in research services of approximately $2.4 million and personnel-related expenses of approximately $0.8 million, offset by an increase in clinical-related expenses of approximately $0.9 million.General and administrative expenses for the third quarter ended September 30, 2024, were approximately $3.9 million, as compared to approximately $3.5 million for the same period in 2023. This increase was due to a $0.5 million increase in professional services, partially offset by a decrease in personnel-related expenses of $0.1 million.For the third quarter ended September 30, 2024, Vincerx reported a net loss of approximately $7.8 million, or $0.17 per share. For the third quarter ended September 30, 2023, Vincerx reported a net loss of approximately $9.0 million, or $0.42 per share.

100%患者获临床缓解的CAR-T疗法；晚期癌症疾病控制率达92%的TCR-T疗法…… | 一周盘点

▎药明康德内容团队编辑本期看点 1. T细胞受体T细胞（TCR-T）疗法IMA203在一项1b期临床试验中令92%转移性黑色素瘤患者的疾病获得控制，且患者的中位缓解持续时间（DOR）超过一年。 2. B细胞成熟抗原（BCMA）靶向自体嵌合抗原受体（CAR）-T细胞疗法Ribrecabtagene autoleucel（DRL-1801）用于治疗复发/难治性多发性骨髓瘤患者的1期临床试验结果亮眼，首批8名接受治疗的患者均获得了临床缓解。 3. 用于治疗胶质母细胞瘤（GBM）的树突状细胞疫苗DOC1021相比于标准治疗（SOC）有望大幅延长患者的中位总生存期（OS）。药明康德内容团队整理 IMA203：公布1b期临床试验数据 Immatics公布了其在研TCR-T疗法IMA203用以治疗转移性黑色素瘤患者的最新1b期临床数据，这些患者先前接受过大量治疗。IMA203是由Immatics专有的ACTengine平台所开发的TCR-T细胞疗法，靶向由HLA-A*02呈递的黑素瘤抗原PRAME。PRAME是一种在各种实体瘤中经常表达的蛋白质，因此IMA203具潜力治疗广泛的癌症患者群体。此次公布的结果显示，92%患者的疾病获得控制且患者的中位DOR超过一年。根据此积极数据，Immatics预定在今年12月启动SUPRAME注册性3期试验，预计病患招募将于2026年完成，并在2026年初进行预定的中期分析。 Ribrecabtagene autoleucel（DRL-1801）：公布1期临床试验数据 Aurigene Oncology公司宣布其新型BCMA靶向自体CAR-T细胞疗法Ribrecabtagene autoleucel（DRL-1801）用于治疗复发/难治性多发性骨髓瘤的1期临床试验中首批8名患者的初步结果。所有患者都接受过大量的前期治疗，中位治疗线数为5.5线。大多数患者此前也曾接受过移植手术，并在移植后出现疾病进展。结果显示，100%的患者获得了临床缓解，其中有5名（62.5%）患者获得了严格的完全缓解（CR）。安全性方面，所有患者均未出现高级别的细胞因子释放综合征（CRS）或神经毒性。 DOC1021：公布1期临床试验的中期数据 Diakonos Oncology公司公布了其树突状细胞疫苗DOC1021用于治疗胶质母细胞瘤患者的1期开放标签试验的中期分析结果。该公司的树突状细胞疫苗由患者自身的免疫细胞与从肿瘤样本中提取的RNA和蛋白质结合制成。这种独特的方法可以靶向完整的癌症抗原谱，而无需进行任何基因修饰。通过利用天然的免疫信号通路，这种策略使免疫系统能将癌细胞视同受病毒感染的细胞一样进行识别和清除。此次公布的结果显示，15例患有挑战性肿瘤、MGMT未甲基化（通常预后不良）患者中有14例存活超过12个月。目前，中位随访时间为16个月，中位OS尚未达到。Kaplan-Meier（KM）分析将接受DOC1021治疗的患者与接受完整SOC的年龄匹配历史对照组患者进行比较，两组在统计学上具有差异（p=0.03）。KM预测接受DOC1021治疗的患者的OS为19.7个月，而接受SOC的未甲基化GBM患者的预期OS为12.7个月。安全性方面，没有剂量限制性毒性或令人担忧的严重不良事件（SAE）。 VIP943：公布1期临床试验数据 Vincerx Pharma公司公布了其抗体偶联药物（ADC）VIP943治疗复发/难治性急性髓系白血病（AML）、高危骨髓增生异常综合征（HR-MDS）和B细胞急性淋巴细胞白血病（B-ALL）的1期临床试验的结果。VIP943由抗CD123抗体、一种在细胞内切割的独特连接子和一种新型驱动蛋白纺锤体蛋白抑制剂（KSPi）有效载荷组成。Vincerx的CellTrapper技术可确保KSPi有效载荷积聚在靶细胞中，限制非靶细胞、非分裂细胞的吸收，从而减少非特异性释放。该1期剂量递增研究共招募了22名患者，他们很少对单一疗法产生应答。9名患者（6名AML患者和3名HR-MDS患者）至少接受了3次有效剂量的VIP943治疗。截至目前，1名复发性AML患者获得了完全缓解伴血液学不完全恢复（CRi），1名HR-MDS患者获得了完全缓解伴较少血液学恢复（CRL）。截至2024年8月的数据，VIP943显示出良好的安全性和耐受性，没有报告剂量限制性毒性，SAE与预期一致。 VK0214：公布1b期临床试验数据 Viking Therapeutics公司公布了其新型甲状腺激素受体β（TRβ）小分子激动剂VK0214在X-连锁肾上腺白质营养不良（X-ALD）患者中进行的1b期临床试验的积极数据。X-ALD是一种罕见的致命代谢性疾病，由ABCD1基因突变引起，这种突变会导致肾上腺脑白质营养不良蛋白（ALDP）功能障碍，从而引起脂肪酸的异常累积。临床前研究表明，甲状腺激素受体β型可以调节ABCD2相关基因的表达，ABCD2能够编码一种称为肾上腺脑白质营养不良相关蛋白（ADLRP）的代偿转运体，通过增加ABCD2表达可以使特定脂肪酸水平恢复正常。此次公布的研究结果表明，在为期28天的研究期间，VK0214每天用药一次的安全性和耐受性良好。此外，与安慰剂相比，接受VK0214治疗患者血浆中的超长链脂肪酸（VLCFAs）和其他血脂水平明显降低。 ▲VK0214治疗28天后患者的VLCFA与基线相比的变化（图片来源：参考资料[5]） ▲VK0214治疗28天后患者的其他血脂与基线相比的变化（图片来源：参考资料[5]） Paxalisib：公布1期临床试验的新数据 Kazia Therapeutics公司公布其口服PI3K/mTOR双抑制剂paxalisib联用放射疗法治疗PI3K通路突变实体瘤脑转移（BM）或软脑膜转移（LM）患者的1期临床试验的数据。此次公布的结果显示，paxalisib联用放疗总体耐受性良好。研究中最常报告的不良反应是恶心、呕吐和高血糖。接受45 mg paxalisib联用放疗患者中有67%获得了部分缓解（PR），接受最大耐受剂量治疗的患者中有超过三分之二的人获得了颅内缓解，这与单独使用全脑放疗的历史缓解率相比毫不逊色。 ELVN-001：公布1期临床试验的新数据 Enliven Therapeutics公司公布其小分子激酶抑制剂ELVN-001治疗复发/难治性或对现有酪氨酸激酶抑制剂（TKI）不耐受的慢性髓系白血病（CML）患者的1期临床试验的积极数据。ELVN-001是一种强效、高选择性、潜在“best-in-class”的小分子激酶抑制剂，专门针对CML患者的致癌驱动因子BCR-ABL融合蛋白。ELVN-001还具有针对耐药性最强的BCR-ABL1耐药突变体T315I和其他已知耐药突变体的活性。截至2024年6月25日的数据，ELVN-001的耐受性保持良好，没有患者减少剂量，未报告≥3级治疗相关的非血液学毒性反应。第24周时，患者的初始累积主要分子缓解（MMR）率为44%（8/18），与已获批的BCR-ABL1酪氨酸激酶抑制剂在1期临床试验中的数据相比具有优势。 Camonsertib：公布1期联合治疗试验数据 Repare Therapeutics公司公布了潜在”best-in-class”口服小分子ATR抑制剂camonsertib结合姑息性放疗，治疗携带ATM突变转移性肿瘤的1期临床试验数据。该试验纳入了17例携带ATM突变的转移性肿瘤患者，其中12人携带致病性ATM基因突变，5人携带ATM基因突变的意义不明变异（VUS）。这些患者的原发性癌症组织学来源包括胃肠道（n=5）、胰腺（n=5）、乳腺癌（n=2）、肺（n=2）、膀胱（n=2）和甲状腺（n=1）。此次公布的结果显示，2个月时，致病性ATM突变组有2例CR、5例PR和4例疾病稳定（SD）患者，而VUS组有1例PR和4例SD患者。6个月时，在9名可评估患者中，致病性ATM突变组有2例CR、4例PR和1例SD患者，而VUS组有1例SD和1例疾病进展患者。该早期临床数据表明camonsertib联合放疗治疗有可能对携带致病性ATM突变的肿瘤患者进行放射增敏，从而获得更高的临床益处。 Misetionamide：公布1期临床试验的中期数据 Panavance Therapeutics公司公布了其小分子疗法misetionamide（GP-2250）联用吉西他滨治疗晚期不可切除或转移性胰腺导管腺癌患者1期临床试验的中期数据。Misetionamide具有独特的作用机制，可抑制两种致癌转录因子c-MYC和NFκB。此次公布的结果显示，与单独使用吉西他滨的历史结果相比，接受misetionamide联用吉西他滨治疗患者的无进展生存期更长，约40%的患者达到PR或SD。此外，misetionamide联用吉西他滨的安全性良好。 ▲欲了解更多前沿技术在生物医药产业中的应用，请长按扫描上方二维码，即可访问“药明直播间”，观看相关话题的直播讨论与精彩回放参考资料（可上下滑动查看） [1] Vincerx Reports Positive Initial Clinical Data from Ongoing VIP943 Phase 1 Dose-Escalation Study and Provides Pipeline and Corporate Updates.

Vincerx Reports Positive Initial Clinical Data from Ongoing VIP943 Phase 1 Dose-Escalation Study and Provides Pipeline and Corporate Updates

VIP943 demonstrates promising safety and tolerability and achieves two complete responses to date in Phase 1 dose-escalation study, reinforcing the program’s potential and validating the VersAptx™ Platform technology Vincerx focusing resources on continued development of VIP943 Expected cash runway into early 2025 Management to host webcast and Q&A today at 5:00 PM EDT to review pipeline and corporate updates, followed by commentary from key opinion leader Dr. M. Yair Levy Oct. 07, 2024 -- Vincerx Pharma, Inc. (Nasdaq: VINC), a biopharmaceutical company aspiring to address the unmet medical needs of patients with cancer through paradigm-shifting therapeutics, announced two complete responses in the ongoing first-in-human, Phase 1 dose-escalation study of VIP943, the Company’s next-generation antibody-drug conjugate (ADC) being evaluated in relapsed/refractory acute myeloid leukemia (AML), higher-risk myelodysplastic syndrome (HR-MDS), and B-cell acute lymphoblastic leukemia (B-ALL). The Company also provided pipeline and corporate updates. The ongoing Phase 1 dose-escalation study of VIP943 has enrolled 22 patients to date across several escalating dose cohorts (0.2 to 1.3 mg/kg once weekly). These 22 patients represent a ‘hard-to-treat’ salvage population, which rarely responds to monotherapy. Nine patients (six AML; three HR-MDS) have received at least three doses of an efficacious dose of VIP943 (i.e., ≥1.0 mg/kg). Of these nine patients, four (44%) remain on study. So far, one patient with relapsed AML has achieved complete remission with incomplete hematologic improvement (CRi) and one patient with HR-MDS has achieved complete remission with limited count recovery (CRL) based on international consensus response criteria. These response criteria are widely recognized as an approvable benchmark in AML and MDS studies, further underscoring the significance of these early results. “We are excited by the emerging data from our Phase 1 study of VIP943, showing clinical responses in difficult-to-treat patients," said Ahmed Hamdy, M.D., Chief Executive Officer of Vincerx. "We believe these promising clinical responses highlight the potential of VIP943 as a best-in-class therapy for CD123+ hematologic malignancies and validate our VersAptx platform’s ability to create safer, more effective bioconjugates by overcoming the challenges of historical ADCs.” As of August 2024, VIP943 has shown favorable safety and tolerability, with no dose-limiting toxicities reported in 22 patients. Serious adverse events (SAEs) have been consistent with expectations for this patient population. The most common SAEs included pneumonia (three patients, 14%), and cellulitis and febrile neutropenia (two patients each, 9%). Only one patient (5%) experienced a drug-related SAE (Grade 3 diarrhea). Target engagement (i.e., receptor occupancy) has been demonstrated by binding of VIP943 to CD123+ peripheral blood blasts from patients with AML from the Phase 1 study. Maximal receptor occupancy of 84% was achieved in the highest dose cohort (1.3 mg/kg). Across all the cohorts, receptor occupancy was retained for less than 96 hours. Concurrent decreases in CD123+ peripheral blood blasts were also observed after dosing. These pharmacodynamic (PD) markers show that VIP943 is binding to and eliminating CD123+ malignant cells. Preliminary pharmacokinetic (PK) data continues to show low release of payload (≤1% in plasma). The half-life of VIP943 is less than 96 hours, and no accumulation occurs with repeat dosing. These PK and PD results have prompted evaluation of twice weekly dosing of VIP943 as a potential “induction” regimen. Enrollment in the once weekly and twice weekly dosing cohorts is ongoing. Dr. Hamdy continued, “Our initial clinical results demonstrate that VersAptx is a next-generation platform that overcomes key challenges associated with traditional ADCs. The PK profile shows that our linker is stable, cleaving exclusively inside cells without extracellular degradation. Our PD results coupled with clinical responses confirm the payload effectively kills cancer cells in peripheral blood and bone marrow without harming nearby healthy tissue. This innovative design with proof-of-concept in Phase 1 reinforces our confidence in VersAptx as a transformative platform for ADC development.” The company anticipates providing another data update on the ongoing Phase 1 VIP943 study by the end of the year. Dr. M. Yair Levy, Director of Hematologic Malignancies Research at Texas Oncology added, "Although this is still early data, VIP943 is clearly differentiated from other ADCs, particularly with its favorable safety profile. We’re not seeing neutropenia as a dose-limiting toxicity, which is encouraging and may allow the drug to move into earlier lines of therapy in combination. I look forward to the continued development of VIP943 and its potential to improve treatment options for patients with CD123+ malignancies.” VIP236 is Vincerx’s first-in-class small molecule drug conjugate (SMDC) being evaluated in an ongoing first-in-human, Phase 1 dose-escalation study as a monotherapy in patients with advanced solid tumors. As of September 2024, 29 patients have been enrolled. Of these patients, 20 were evaluable per-protocol for response from the every 2- or 3-week schedule; nine of 20 patients had stable disease for a disease control rate of 45%. In addition, one of these subjects has been on treatment for over 300 days and four additional patients were on study for more than 120 days, demonstrating promising monotherapy duration of response in patients with advanced cancer. VIP236 continued to show a favorable safety and tolerability profile in these 29 patients, with no instances of the dose-limiting side effects commonly associated with camptothecins, such as life-threatening diarrhea, severe stomatitis/mucositis, or interstitial lung disease. These results support the potential role of VIP236 as a strong combination agent for the treatment of advanced cancers. Considering the promising VIP236 clinical data, the Company intends to pursue a strategic partner to champion its future development for the benefit of patients. “We've made significant progress in identifying an effective dose and schedule. We believe it is now crucial to study VIP236 in the right patient population, which could include triple-negative breast cancer and gastric cancer, where camptothecins are used, especially in combination with other anticancer agents,” added Dr. Hamdy. By transitioning VIP236 to a partnering asset, the Company plans to streamline its operations and focus its efforts on the continued development of its lead ADC, VIP943. Enitociclib, a highly selective CDK9 inhibitor, is currently being evaluated in a Phase 1 dose-escalation study in combination with venetoclax and prednisone for relapsed/refractory diffuse large B-cell lymphoma (DLBCL) and peripheral T-cell lymphoma (PTCL), in collaboration with the National Institutes of Health (NIH). As of September 2024, the study reported four partial responses (PRs) in seven patients (57% overall response rate), including one patient with double hit lymphoma (DH-DLBCL) and three patients with PTCL. All responses occurred in patients considered refractory by SCHOLAR-1 criteria and included one patient with prior CAR-T therapy. The study is currently enrolling in the third dose level (enitociclib 30 mg [efficacious dose] and venetoclax 600 mg) with two patients enrolled to date. Additionally, in a separate Phase 1 study of enitociclib as a monotherapy (30 mg), one patient with transformed follicular lymphoma achieved a metabolic PR. As of September 2024, this patient remains on enitociclib monotherapy after more than 26 months. Overall, these clinical results continue to show the promising safety, tolerability, and efficacy of enitociclib for the treatment of relapsed/refractory lymphoma. The Company is actively focused on finding a strategic partner to continue the development of this asset. VIP236, the first-in-class SMDC from the VersAptx Platform, consists of an αvβ3 integrin binder, a neutrophil elastase linker cleaved in the tumor microenvironment, and a camptothecin payload optimized for high permeability and low active efflux. VIP236 was designed to deliver its payload to advanced/metastatic solid tumors that express αvβ3. VIP236 is being evaluated in a first-in-human, Phase 1 dose escalation study in patients with advanced malignancies (NCT05712889). VIP943, the first ADC from the VersAptx platform, consists of an anti-CD123 antibody, a unique linker cleaved intracellularly by legumain, and a novel kinesin spindle protein inhibitor (KSPi) payload enhanced with Vincerx’s CellTrapper™ technology. Vincerx’s proprietary effector chemistry (linker + payload) was designed to reduce non-specific release of the payload and ensure payload accumulation in cancer cells versus healthy cells. The increased therapeutic index has the potential to address challenges associated with many ADCs by improving efficacy and reducing severe toxicities. VIP943 is being evaluated in a Phase 1 dose-escalation trial in patients with relapsed/refractory AML, HR-MDS, and B-ALL who have exhausted standard therapeutic options (NCT06034275). Enitociclib, a highly selective CDK9 inhibitor, is currently being evaluated in a Phase 1 dose-escalation study (NCT05371054) in combination with venetoclax and prednisone for DLBCL and PTCL, in collaboration with the NIH. Enitociclib has demonstrated favorable safety and PK, with significant clinical benefits across various indications, including durable complete metabolic remissions in patients with double-hit (DH)-DLBCL and stable disease in solid tumors, notably in ovarian cancer, suggesting promising potential for future combination studies. VersAptx is a versatile and adaptable next-generation bioconjugation platform. The modular nature of this innovative platform allows the combination of different targeting, linker, and payload technologies to develop bespoke bioconjugates that address different cancer biologies.
