Single Dose Investigator Initiated Pilot Study to Investigate CYTALUX (Pafolacianine) for Intraoperative Detection of Malignant Tissue in Subjects Undergoing Surgical Resection for Cancer.

The goal of clinical trial is to test an FDA approved drug called Pafolacianine that attaches to cancer cells and lights up when seen through a special camera system in adults with a suspected primary diagnosis, or a high clinical suspicion of gastrointestinal, fore gut, pancreatic, hepatobiliary, esophageal malignancies and gyn malignancies planned for HIPEC/debulking, warranting surgery. The main question it aims to answer is:
• Can CYTALUX™ (pafolacianine) injection used with near-infrared (NIR) fluorescent imaging improve the detection of malignant tissue in subjects undergoing surgical resection for cancer? Participants taking part in this study will receive the study medication. Then, during the surgery the investigator team will turn on the camera to evaluate if the tumor is visible with the help of the study medication. Taking part in this study will last about 2 months.

Pafolacianine for Localization of Pediatric Extracranial Solid Tumors

This phase III trial studies how well pafolacianine works for identifying cancerous lesions in children and adolescent patients with primary solid tumors or solid tumors that have spread from where they first started (primary site) to other places in the body (metastatic). Pafolacianine is a fluorescent imaging agent that targets folate receptors which are overexpressed in many cancers and is used with near infrared (NIR) imaging during surgery to identify tumor cells. NIR uses a special camera that uses wavelengths in the infrared range to visualize and locate the tumor cells that are lit up by the pafolacianine. Giving pafolacianine for NIR imaging may work better than other imaging agents in identifying cancerous lesions in pediatric patients with solid tumors.

Enhancing surgical precision in ovarian cancer with FRα-fluorescence-guided surgery

Review

作者: Scambia, Giovanni ; Ceccaroni, Marcello ; Bogani, Giorgio ; Ferrari, Filippo Alberto ; Francesco, Raspagliesi ; Fagotti, Anna ; Pavone, Matteo ; Bourdel, Nicolas

INTRODUCTION:

Complete cytoreduction is a key prognostic factor in advanced ovarian cancer. Folate receptor alpha (FRα)-targeted intraoperative fluorescence imaging has emerged as a promising tool to enhance identification of tumor localization. Agents like pafolacianine (OTL38) and EC17 improve real-time visualization of malignant lesions, overcoming limitations of conventional methods relying on visual inspection and palpation.

MATERIALS AND METHODS:

we conducted a systematic review to evaluate the safety, efficacy, and feasibility of FRα-targeted fluorescence imaging in ovarian cancer surgery. Studies were identified through comprehensive searches in PubMed, Scopus, and Web of Science. Clinical and preclinical studies assessing FRα-targeted agents with near-infrared or other fluorescence modalities were included. Bias risk was assessed using the Cochrane Risk of Bias Tool for randomized trials and the Newcastle-Ottawa Scale for non-randomized studies.

RESULTS:

Eleven studies, including clinical and preclinical trials, were analyzed. OTL38 significantly improved lesion detection, identifying additional malignant lesions in 33 % of patients undergoing debulking surgery and enhancing detection by 29 % over standard methods, with sensitivity exceeding 85 %. EC17, assessed in smaller studies, identified 16 % more malignant lesions undetected by conventional methods, though autofluorescence was a challenge. Adverse events, predominantly mild, included nausea, vomiting, and transient skin flushing.

CONCLUSIONS:

FRα-targeted imaging may enhance lesion detection during cytoreductive surgery, increasing resection completeness. While EC17 shows feasibility, larger trials support the potential of OTL38. Future research should optimize imaging agents to reduce autofluorescence and assess their impact on survival outcomes.

Real-world localization of cancer in lungs with a commercially available folate receptor-targeted fluorescent agent for intraoperative molecular imaging

Article

作者: Ajabshir, Navid ; Baker, Nicholas ; Sarkaria, Inderpal S ; Alicuben, Evan T ; Levy, Ryan M

Background:

Intraoperative molecular imaging (IMI) can improve lung nodule localization and the ability to perform sublobar resection. Following Food and Drug Administration approval of pafolacianine, we report on the integration of this folate receptor (FR)-targeted fluorescent agent into a minimally invasive thoracic surgery practice.

Methods:

Cases from June 2023 through January 2024 were reviewed. Patients with primary or metastatic cancer in the lung with plans for sublobar pulmonary resection were included. Preoperative computed tomography scans were used to determine lesion size and depth. Pafolacianine infusion was performed within 24 hours of surgery. The lung was inspected for fluorescence using the Stryker 1788 imaging system.

Results:

The study cohort comprised 39 patients (28 females and 11 males), with a median age of 68 years. The median lesion size was 13 mm (range, 5-32 mm), and median depth was 6.4 mm (range, 0-30 mm). Minimally invasive resection (robotic-assisted thoracoscopic surgery, n = 21; video-assisted thoracoscopic surgery; n = 18) was performed in all patients (segmentectomy, n = 15; wedge resection, n = 17; segmentectomy and wedge resection, n = 3; lobectomy, n = 4). In 11 patients, the primary lesion was not detectable under visual inspection with white light but was visualized with IMI. The final histology included primary lung cancer in 28 patients and metastatic cancer in 11 patients. All margins were negative.

Conclusions:

This report of early postmarketing experience with pafolacianine for cancer in the lung demonstrated a high rate of nodule localization. These early experiences further reinforce IMI as an adjunct to surgical resection that may enhance the ability to perform minimally invasive parenchymal-sparing operations.

Intraoperative Molecular Imaging With Pafolacianine: Histologic Characteristics of Identified Nodules

Article

作者: Sarkaria, Inderpal S ; Martin, Linda W ; Singhal, Sunil ; Reddy, Rishindra M ; Murthy, Sudish C ; Barret, Tina ; Biro, Timothy G ; Lopez, Alex S ; Rice, David C ; Stevens, Gary

BACKGROUND:

With increased early detection efforts, surgery for early-stage lung cancer is expected to rise. Pafolacianine is the first FDA approved targeted optical imaging agent indicated as an adjunct for intraoperative identification of malignant and nonmalignant pulmonary lesions in adult patients with known or suspected cancer in the lung.

METHODS:

This is a retrospective review of the malignant and nonmalignant lesions identified by pafolacianine with intraoperative molecular imaging (IMI) in the multi-center Phase 2 and Phase 3 ELUCIDATE clinical trials. All lesions meeting the intent to treat criteria from the combined studies were included. Histopathology for malignant and nonmalignant lesions and immunohistochemistry (ICH) for folate receptor alpha (FRα) and folate receptor beta (FRβ), which pafolacianine binds to, were assessed.

RESULTS:

A total of 273 lesions resected from 191 patients were analyzed. The identification of primary and occult malignant lesions with pafolacianine in combination with standard practice was improved (P < .001) when compared to standard practice alone. A range of histologies were demonstrated including adenocarcinoma (primary and metastatic), squamous cell carcinoma, adenoid cystic carcinoma, chordoma, lymphoma, and papillary thyroid cancer. Ninety-two percent (205 of 223) of lesions tested for folate expression were positive for FRα or FRβ expression.

CONCLUSIONS:

While initially intended to identify adenocarcinoma, IMI with pafolacianine targets a broad histological cross-section of malignant and nonmalignant primary and metastatic lesions in the lung. As real-world use expands, additional insight will continue to inform utility of pafolacianine in clinical practice and may broaden clinical applicability.

一文读懂：叶酸受体α（FRα）与多种癌症的神秘关联及靶向治疗突破

01叶酸及叶酸转运体概述叶酸代谢与肿瘤药物研发叶酸代谢在人体生物化学中至关重要，参与一碳代谢，有助于三个基本的生物合成途径：从头核苷合成、甲基化反应和氨基酸生产。但在肿瘤发生过程中会被破坏，可为肿瘤细胞的增殖提供物质基础，因此长期以来都是肿瘤药物研发的热门靶点。早期的抗叶酸药物如氨蝶呤及其后续的甲氨蝶呤、培美曲塞等，至今仍在临床广泛应用。叶酸与叶酸转运体叶酸即维生素B9，是人体必需的营养素，缺乏会导致贫血和发育缺陷。饮食中的叶酸无生物活性，需还原为活性四氢叶酸(THF)形式且携带不同的一碳单位，才能参与细胞的生物合成过程。叶酸是亲水性阴离子分子，难以自由穿过生物膜，其进入哺乳动物细胞依赖于还原型叶酸载体(RFC)、质子偶联叶酸转运体(PCFT)和叶酸受体(FRs)三种主要的转运体。图1 三种类型的叶酸转运蛋白叶酸受体(FRs)亚型FRs有四种亚型，分别为FRα、FRβ、FRγ和FRδ，由FOLR1-4基因编码，其中FRα是研究的重点。各亚型在叶酸结合亲和力和组织分布上存在差异。FRβ存在于胎盘、造血组织等，在肿瘤相关巨噬细胞中高表达，可作为M2调节性巨噬细胞极化的生物标志物和潜在免疫治疗靶点；FRγ是分泌蛋白，主要在造血组织表达，功能尚不明确；FRδ缺乏经典的叶酸结合口袋，对叶酸亲和力低，在受精过程中起重要作用，还可能是CD4+T滤泡辅助细胞激活的生物标志物。表1 叶酸受体亚型在正常组织和恶性组织中的分布与表达02FRα的生物学特征概述FRα的结构FRα是一种38-40kDa富含半胱氨酸的糖蛋白，通过羧基末端的GPI锚定在细胞膜上。它具有球状结构，包含一个深而开放的叶酸结合口袋，能高亲和力结合叶酸及其衍生物，这种结构特点为设计叶酸偶联药物和抗FRα疗法提供了基础。图2 FRα和叶酸之间的相互作用示意图FRα的表达在正常生理情况下，FRα主要表达在脉络丛、肺、甲状腺、视网膜和胎盘等极化上皮细胞的顶端或腔面。在病理情况下，多种肿瘤组织中FRα过表达。图3 FRα在恶性和正常组织中的表达FRα的氨基酸序列SignalChainPropeptide1-2424-234235-257MAQRMTTQLLLLLVWVAVVGEAQTRIAWARTELLNVCMNAKHHKEKPGPEDKLHEQCRPWRKNACCSTNTSQEAHKDVSYLYRFNWNHCGEMAPACKRHFIQDTCLYECSPNLGPWIQQVDQSWRKERVLNVPLCKEDCEQWWEDCRTSYTCKSNWHKGWNWTSGFNKCAVGAACQPFHFYFPTPTVLCNEIWTHSYKVSNYSRGSGRCIQMWFDPAQGNPNEEVARFYAAAMSGAGPWAAWPFLLSLALMLLWLLSFRα的生理功能FRα作为叶酸转运体，结合叶酸衍生物，参与叶酸的摄取和转运；可作为转录因子发挥作用；还在胚胎发育中至关重要，可能介导胚胎神经管的形成、母婴间的叶酸转运。缺乏FRα会导致胚胎发育异常、器官功能受损等问题。图4 FRα介导的细胞内吞作用和信号通路FRα在肿瘤中的作用①促进肿瘤细胞代谢：FRα通过为癌细胞提供叶酸，促进肿瘤细胞代谢，进而推动肿瘤发生。然而，由于叶酸稳态主要由RFC控制，FRα在这一过程中的重要性存在争议。②驱动肿瘤发展的转录因子功能：FRα的核转位与癌细胞的增殖以及癌症干细胞的重编程有关，其可激活多个转录因子，如OCT4/SOX2、KLF4、HES1和FGFR4等，这些转录因子分别调节干细胞特性、细胞重编程、转移和多药耐药以及细胞增殖。③与促癌信号通路相互作用：FRα可直接与促进肿瘤发生的信号通路相互作用。例如，叶酸-FRα复合物能借助共受体gp130，以JAK依赖的方式激活致癌的STAT3；FRα还被认为与丝氨酸/苏氨酸激酶ERK1/2相互作用，调节TP53基因转录；在卵巢癌中，敲低FRα可通过下调细胞-细胞粘附分子E-cadherin，抑制细胞增殖和迁移。图5 FRα表达与癌症发展之间的相关性03FRα在癌症诊断和治疗中的应用癌症诊断方面作为诊断标志物：FRα在多种癌症中呈现高表达，像卵巢癌、乳腺癌、子宫内膜癌等，而在正常组织中表达有限，这种差异表达使其可作为诊断癌症的重要生物标志物。例如，通过检测血清中FRα的含量，有助于卵巢癌的早期诊断和病情监测。多种检测手段的核心：多种方法可用于检测FRα活性，实现癌症的精准诊断。如全身单光子发射CT、FRα-靶向对比增强磁共振成像(MRI)等，能在分子和细胞水平可视化癌症变化，为早期检测和个性化治疗提供依据。表2 FRα表达水平升高的癌症类型的各种例子癌症治疗方面指导靶向治疗：FRα的过表达特性使其成为癌症靶向治疗的理想靶点。基于此开发的多种治疗方法，如叶酸偶联物、单克隆抗体等，可将细胞毒性药物精准输送到癌细胞，减少对健康细胞的损害。免疫治疗的重要靶点：针对FRα产生的抗体，可介导免疫细胞对肿瘤细胞的杀伤作用，为癌症免疫治疗提供了新策略。免疫介导的靶向FRα阳性肿瘤的治疗方法，包括过继转移肿瘤特异性T淋巴细胞、双特异性抗体靶向T细胞疗法和免疫细胞因子等，能有效抑制癌细胞的生长和转移。增强治疗效果：通过调节FRα的表达，可以提高抗癌治疗的效果。在卵巢癌治疗中，顺铂与FRα的相互作用影响癌细胞的凋亡和细胞周期，FRα过表达的癌细胞对顺铂更敏感，因此FRα可作为提高卵巢癌对顺铂治疗敏感性的潜在靶点。图6 FRα在癌症诊断和治疗中的潜在应用的未来方向局限性靶向FRα进行癌症诊断和治疗都存在一定局限性。诊断方面，检测方法存在灵敏度和特异性的问题，且放射性标记的叶酸主要成像于脾脏、肝脏和肾脏的FR，其他组织的FR难以检测。治疗方面，虽然副作用较少，但癌症细胞可能对治疗产生耐药性，且治疗费用较高。04FRα的靶向药物及其他应用图7 FRα靶向疗法及其作用机制单克隆抗体如Farletuzumab、KHK2805、MOv19、MOv18-IgG1和MOv18-IgE等，它们通过不同机制发挥抗癌作用，部分已进入临床试验阶段，但结果各异。Farletuzumab是一种人源化IgG1单克隆抗体，通过激活补体依赖的细胞毒性(CDC)等机制发挥抗癌作用，临床试验显示其在部分患者中有效，但在一些试验中未达到预期疗效。KHK2805是一种新型人源化抗体，对FRα不同表位有高亲和力，采用去岩藻糖基化设计，增强ADCC和CDC活性，在卵巢癌临床前模型中展现出显著活性，但后续开发情况不明。MOv19是一种通过杂交瘤技术制备的鼠源IgG2a抗体。此外，MOv19还被广泛改造用于多种治疗策略，其经改造生成了嵌合抗体ChiMOv19和人源化衍生物M9346A。MOv18-IgG1是与MOv19平行产生的抗体，鼠源MOv18克隆经放射性标记用于评估临床可行性，但患者易产生人抗鼠抗体(HAMA)。改造后的嵌合MOv18抗体可发挥ADCC活性，在早期试验中能有效定位到卵巢癌组织，但后续未再有开发报道。MOv18-IgE是首个针对FRα的嵌合IgE抗体，基于IgE的特性，在临床前模型中展现出良好疗效，但在早期临床试验中发现可能会引发短暂性荨麻疹等副作用。CAR-T细胞疗法通过工程化改造T细胞，使其表达针对FRα的抗原特异性单链可变片段抗体，从而靶向肿瘤细胞。针对FRα的CAR-T细胞疗法在临床前研究中显示出抗癌潜力，但I期试验中因T细胞存活不佳未观察到肿瘤负担减轻，目前研究主要集中在提高T细胞的持久性和疗效上。如MOv19-BBζ等第二代抗FRα-CAR-T细胞构建体，在体内试验中展现出更好的T细胞持久性和抗肿瘤活性，但该疗法面临鼠源scFv序列引发HAMA反应等问题。图8 CAR-T细胞疗法TIL疗法利用从患者肿瘤中收集的T细胞，与FRα靶向分子结合进行治疗。例如ITIL-306，可增强T细胞活性，目前一项评估其安全性和可行性的多癌种1期剂量递增和扩展研究正在进行中。表3 靶向FRα的临床开发中的抗体和T细胞疗法示例抗体-药物偶联物多种ADC药物正在研发中，Mirvetuximab-Soravtansine(MIRV)是首个获批用于治疗FRα阳性铂耐药卵巢癌的ADC药物，由人源化抗FRα单克隆抗体、可裂解连接子和细胞毒性药物DM4组成，但可能导致可逆性眼部不良事件。此外，MORAb-202、Luveltamab-Tazevibulin和STRO-002等ADC药物也在进行临床试验，各自具有独特的结构和作用机制，显示出一定的潜力。图9 FRα的ADC药物结构示意图以及MIRV的作用机制表4 靶向FRα的临床开发中的ADC示例叶酸-药物偶联物(FDCs)将细胞毒性药物与叶酸结合，通过FRα进入细胞发挥作用。Vintafolide是较为成功的FDC，但在III期临床试验中未达到预期效果，其他FDCs如EC131、EC2629等仍处于研究阶段。图10 Vintafolide的结构及其作用机制疫苗以FRα为靶点的疫苗可诱导免疫系统产生抗体，作为维持治疗手段预防疾病复发。早期研究证实了其安全性，与免疫检查点抑制剂联合使用可增强T细胞反应，目前相关试验主要在乳腺癌和卵巢癌患者中开展。表5 以FRα为靶点的疫苗的临床试验小分子-药物偶联物(SMDCs)叶酸-药物偶联物如EC145，在前期试验有一定效果，但III期临床试验未达到无进展生存期终点，且部分药物因毒性问题研发停滞。BGC945是一种针对FRα的胸苷酸合酶抑制剂，在I期临床试验中观察到对部分卵巢癌患者有临床益处。表6 FRα的临床试验清单联合治疗策略与化疗联合：多数FRα靶向单克隆抗体已与化疗联合应用，但尚无单克隆疗法在3期研究中显示出优于标准化疗的生存获益。相比之下，ADC联合化疗的研究相对较少，但部分ADC与化疗联合在临床前研究中显示出更好的抗肿瘤效果，相关临床试验正在进行中，有望确定新的治疗标准。与靶向药物和免疫疗法联合：如MIRV与贝伐单抗、免疫疗法药物的联合治疗，初步研究显示出一定的潜力，但仍需进一步临床试验验证。FRα的其他应用术中肿瘤识别：FDA批准的荧光药物Pafolacianine可与FRα结合，用于术中识别卵巢癌和肺癌的残留或隐藏肿瘤，提高手术的精准性和患者的预后。在卵巢癌手术研究中，33%的FRα阳性患者通过该方法检测出残留癌组织，检测灵敏度达83%，且62.4%的患者实现了完全R0切除，有助于提高手术精准度，改善患者预后。纳米颗粒疗法：FRα在癌细胞中高表达且能被细胞内吞，借助纳米技术可将化疗药物精准递送至癌细胞，增强治疗效果并减少全身副作用。如肝素-叶酸-紫杉醇(HFT)、Nab-紫杉醇-叶酸等纳米颗粒结合物已在多种癌症治疗中显示出优势，提高了药物递送效率和肿瘤杀伤效果，为癌症治疗提供了新策略。预后标志物：多项研究表明，FRα表达水平与多种癌症的预后相关。在乳腺癌、肺癌、子宫内膜癌和卵巢癌等多种癌症中，FRα高表达往往与患者较差的总生存期(OS)相关，且与肿瘤分级、结节数量和FIGO分期等相关。但在三阴性乳腺癌中，其表达与较好的无侵袭性疾病生存期(IDFS)相关，可辅助医生预测患者预后，制定更合适的治疗方案。化疗耐药替代指标：FRα表达与化疗耐药有关，在卵巢癌中，FRα高表达的患者对化疗反应不佳，它可抑制细胞毒性药物诱导的细胞凋亡。它可能通过调节MDM2和p53等分子影响癌细胞对化疗药物的敏感性。未来，FRα有望作为化疗耐药的替代指标，指导临床选择更有效的治疗方案。ctDNA检测：通过ApoStream技术和激光扫描cytometry可检测血液中FRα阳性的循环肿瘤细胞(CTCs)，为FRα表达癌症的诊断、监测和治疗指导提供了一种非侵入性方法，在非小细胞肺癌中，FRα-ctDNA可作为EGFR阳性的替代指标，辅助诊断。05HER3在多种癌症中的异常表达及影响卵巢癌FRα在约80%的原发性和复发性卵巢癌中过表达，其高表达与疾病分期和分级相关，血清sFR可作为EOC复发标志物，可通过下调肿瘤抑制因子cav-1促进肿瘤发生。可作为生物标志物用于疾病监测、判断患者对治疗的反应以及筛选适合靶向治疗的患者。此外，对一线铂类治疗耐药且术后有残留疾病的患者，其FRα水平较高，具有预后价值，且化疗不影响FRα表达，因此FRα拮抗剂成为上皮性卵巢癌的研究靶点，为卵巢癌治疗带来了新希望。宫颈癌和子宫内膜癌宫颈癌恶性转化时，FRα染色情况会发生变化，且其与FR活性相关，FRα及ERK信号蛋白水平与宫颈病变严重程度正相关。在子宫内膜癌中，FRα过表达与预后不良和无进展生存期缩短有关，且FRα表达水平在子宫内膜样腺癌中显著高于子宫内膜增生，可能参与恶性转化，可作为早期干预的靶点。乳腺癌在乳腺癌研究中，FRα状态与分期及其他标志物相关。其过表达与不良预后相关，包括无病生存期降低，通过PET和MRI等成像技术可检测其表达，指导治疗。在I-III期浸润性导管癌中，30%的样本呈FRα阳性，且三阴性乳腺癌(TNBC)与FRα阳性相关性最强，FRα的表达与较好的无侵袭性疾病生存期(IDFS)相关，但对总生存期(OS)的影响存在争议。雌激素受体阳性可能对高FRα水平有保护作用并下调其表达，因此高FRα表达的TNBC患者值得进一步研究并采用靶向抗叶酸疗法。肺癌在肺癌方面，约72%的恶性胸膜间皮瘤FRα水平升高2-4倍，但使用培美曲塞治疗，对FRα高表达患者的疗效改善不明显。在非小细胞肺癌(NSCLC)中，FRα表达与快速细胞周转相关，且与较好的预后有关。FRα在肺腺癌中表达更高，尤其是表皮生长因子受体(EGFR)突变的肿瘤以及非吸烟者和早期阶段的肿瘤。这使得FRα成为NSCLC治疗的一个有潜力的靶点，针对FRα的研究可能为NSCLC患者提供更精准的治疗方案。头颈部鳞状细胞癌头颈部鳞状细胞癌中，FRα阳性与不良临床结局相关，约45%的原发性肿瘤呈FRα阳性，无FRα阳性表达的患者生存期更长，提示FRα高表达是疾病严重程度和死亡率的重要风险因素。胃肠道癌症在胃肠道癌症中，FRα的存在与多种因素相关，可作为预后因素及潜在的治疗靶点。在胃癌中，FRα的表达与预后不良相关，且与淋巴血管浸润和淋巴结外疾病有关。它可作为一种非侵入性筛查工具，用于胃癌的早期诊断，比癌胚抗原(CEA)更具优势。在结直肠癌中，其表达与癌组织相关(33%-44%的癌组织表达，而正常结肠组织或腺瘤仅7%)，且与患者年龄、转移及非高频微卫星不稳定状态有关。研究发现，IV期结直肠癌伴肝转移患者中，术后生存期短的患者FRα表达显著更高。在胰腺癌中，FRα阳性的手术标本患者预后较差，不过其对无进展生存期影响不显著。此外，胰腺癌还主要表达FRβ，可作为分子靶向治疗的考虑对象。其他癌症在间皮瘤、口腔癌、黑色素瘤等癌症中，FRα也呈现高表达状态。在间皮瘤中，其表达情况影响治疗方案的选择；在口腔癌中，可利用FRα将化疗药物靶向递送至癌细胞，增强治疗效果；在黑色素瘤中，纳米颗粒技术借助FRα可提高免疫治疗药物的递送效率，为黑色素瘤的治疗提供新途径。图11

On Target Laboratories Appoints Bill Peters as CEO

WEST LAFAYETTE, Ind., Dec. 10, 2024 /PRNewswire/ -- On Target Laboratories, Inc., a leading biotechnology company specializing in the development of intraoperative molecular imaging agents to target and illuminate cancer during surgery, today announced the appointment of Bill Peters as president and chief executive officer. Peters has also joined the company's board of directors. He succeeds Ben Lundgren, who served as CEO since 2023 and was with the company for nearly six years. Continue Reading Bill Peters, president and chief executive officer, On Target Laboratories "Ben has been a pivotal force in advancing the commercialization of CYTALUX, building our Sales and Marketing organization, establishing strategic partnerships, and forging key customer relationships. We are deeply grateful for his leadership," said Scott Huennekens, Executive Chairperson of the Board at On Target Laboratories. "We are excited to welcome Bill as our new CEO. His impressive track record of driving success at large organizations uniquely positions him to scale On Target and continue delivering value for both our customers and investors." Peters brings more than 20 years of leadership experience in the medical technology sector, including a decade of executive leadership at ConMed. Most recently, he served as President of the Advanced Surgical and Advanced Endoscopic Technologies businesses in ConMed's General Surgery division, where he played a crucial role in driving a significant portion of the company's sales and profit growth. Under his leadership, General Surgery completed three successful acquisitions, launched innovative new products and emerged as the primary growth engine for the company. Prior to ConMed, Peters held senior commercial roles at Mako Surgical Corporation, which was acquired by Stryker in 2013, and at Intuitive Surgical. Earlier in his career, he also held sales leadership positions at Stryker Corporation. Peters holds a Bachelor of Business Administration in Finance from Ohio University. "I am both honored and excited to take on this leadership role at such an impactful company," said Peters. "The work we are doing to provide patients with groundbreaking technology and renewed hope is incredibly inspiring. I look forward to working alongside our exceptional team to advance our mission to illuminate cancer intraoperatively so it can be removed completely." About On Target Laboratories, Inc. On Target Laboratories discovers and develops targeted intraoperative molecular imaging agents to illuminate cancer during surgery. Their molecular imaging technology, based on the pioneering work of Philip S. Low, PhD, Purdue University's Presidential Scholar for Drug Discovery and the Ralph C. Corley Distinguished Professor of Chemistry, is comprised of a near-infrared dye and a targeting molecule, or ligand, that binds to receptors overexpressed on cancer cells. The imaging agents illuminate the cancerous tissue, which may enable surgeons to detect more cancer that otherwise may have been left behind. CYTALUX, the company's first product, received FDA approval of a New Drug Application for ovarian cancer in November 2021 and a supplemental New Drug Application for lung cancer in December 2022. CYTALUX targets the folate receptors commonly found on many cancers, binds to the cancerous tissue, and illuminates under near-infrared light. A single dose of the agent is administered via intravenous infusion prior to surgery and assists surgeons in visually identifying additional cancerous tissue to be removed during the operation.
