CivaTech Oncology’s mission is to provide improved radiation therapy directly to localized tumors. The Company has developed a novel, polymer-encapsulated, membrane-like radiation source that emits radiation on only one side of the device – the CivaSheet. This directional source is compatible with open and minimally invasive surgical techniques and has FDA clearance to be used as primary or combined cancer therapy. The CivaSheet is a partially bio-absorbable implant that can be applied at the time of the initial surgery. The CivaSheet decreases the time between surgery and radiation therapy, which is a benefit to the patient. Additionally, the CivaSheet can shield healthy tissues while irradiating the diseased tissue or tumor margin. This shielding enables the CivaSheet to be implanted close to radiosensitive structures without overdosing them – a huge advantage for cancers in the abdomen. In Phase I, CivaTech Oncology will confirm the CivaSheet does not move after implantation and that excellent dosimetry can be achieved. The CivaSheet will be implanted during the Whipple procedure for pancreas resection – a standard of care procedure for resectable pancreatic patients. The CivaSheet will benefit these patients by delivering radiation therapy at the time of initial surgery to minimize delay in the treatment. Pancreatic cancer is an aggressive disease that progresses quickly. Faster treatment cycles are ideal for cancer types that proliferate quickly. In Phase I, the safety of CivaSheet and general recommendations for its use in this patient population will be assessed. A Clinical Evaluation Team will review the clinical trial protocols, plans for implants, sample dosimetry that can be achieved and, eventually, each patient case to evaluate device related events. The Clinical Evaluation Team will agree with Physicians on site to continue treating patients in Phase II. The Phase II will consist of two concurrent clinical trials exploring the use of the CivaSheet as monotherapy or boost therapy in resectable pancreatic cancer patients. The rate of local recurrence in patients implanted with CivaSheet will be compared to the current rate of 30%. Additionally, the quality of life, pain, and mortality in each patient will be monitored. CivaSheet will reduce the radiation delivered to adjacent duodenum, stomach, and liver and should result in fewer side effects. Additionally, it will provide a conformal dose, reduce the risk for infection, and possibly reduce treatment related side effects. The Clinical Evaluation Team will review each patient case to discuss patient specific differences impacting the device to increase knowledge and benefit future surgical procedures. CivaSheet is a truly unique brachytherapy device that has the potential to become the first line of defense for localized cancer. CivaTech Oncology is committed to making the CivaSheet available to cancer patients in multiple indications.

CivaTech Oncology的使命是直接向本地化患者提供改进的放射治疗 肿瘤。该公司开发了一种新型的、聚合物封装的膜状放射源 它只在设备的一侧--CivaSheet--发出辐射。此定向信号源是兼容的 具有开放和微创手术技术，并已获得FDA批准，可用作主要或 癌症综合疗法。CivaSheet是一种可部分生物吸收的植入物，可应用于 初次手术的时间。Civa Sheet缩短了手术和放射治疗之间的时间， 这对病人是有好处的。此外，CivaSheet还可以在照射时保护健康组织 病变组织或肿瘤边缘。这种屏蔽使CivaSheet能够在近距离植入 对辐射敏感的结构，而不会过量--这对腹癌来说是一个巨大的优势。 在第一阶段，CivaTech肿瘤科将确认CivaSheet在植入后不会移动，并且 这种出色的剂量学是可以实现的。Civa Sheet将在惠普尔手术期间植入 胰腺切除程序-可切除胰腺患者的标准护理程序。这个 CivaSheet将通过在初始手术时提供放射治疗来使这些患者受益 尽量减少治疗中的延误。胰腺癌是一种进展迅速的侵袭性疾病。 更快的治疗周期是快速扩散的癌症类型的理想选择。在第一阶段， 将评估CivaSheet及其在该患者群体中使用的一般建议。一家临床诊所 评估小组将审查临床试验方案、植入物计划、样本剂量测定 实现并最终评估每个患者案例中与设备相关的事件。临床评价 团队将与现场医生达成协议，继续在第二阶段治疗患者。 第二阶段将包括两个同时进行的临床试验，探索CivaSheet AS的使用 可切除胰腺癌患者的单一疗法或强化疗法。年的局部复发率 植入CivaSheet的患者将与目前30%的比例进行比较。另外，质量 将对每个患者的生命、疼痛和死亡率进行监测。Civa Sheet将减少辐射 注射到邻近的十二指肠、胃和肝脏，副作用应该更少。另外， 它将提供适形剂量，降低感染风险，并可能减少与治疗相关的副作用。 效果。临床评估小组将审查每个患者的病例，以讨论患者的具体差异 影响设备，以增加知识，并使未来的外科手术受益。 CivaSheet是一种真正独特的近距离放射治疗设备，有可能成为第一线 对局部癌症的防御。CivaTech Oncology致力于将CivaSheet提供给 多种适应症的癌症患者。
