U.S. cancer survivors face new test in long-term care
Tuesday, June 5, 2012 By Debra ShermanCHICAGO (Reuters) - Mario Alberico got his education in oncology the hard way. He has lived with cancer and the long-term effects of his treatment for most of his life.At 51, Alberico has finally assembled a team of doctors near his home in suburban Chicago to manage his care. Before that, he saw one doctor after another who failed to recognize serious health problems that stemmed from radiation and chemotherapy drugs used to treat his bone cancer decades earlier.During his senior year of high school, Alberico, the seventh of nine children supported by his widowed mother, got radiation and rotated through 4 different chemotherapy drugs at high doses that eradicated the cancer. Each one of those drugs can have grave long-term effects.As Alberico and many other cancer patients have learned, most doctors outside the oncology community never learned about the impact cancer treatment may have on the longer lifespan they fought to achieve.That has deep implications for the ranks of U.S. cancer survivors, which have quadrupled to nearly 12 million people since the 1970s, according to the National Cancer Institute.Alberico has already had several close calls. The most alarming episode happened about 10 years ago, after he attended a seminar for survivors through the Robert H. Lurie Comprehensive Cancer Center of Northwestern University.There he learned that adriamycin, one of the chemotherapy drugs he was treated with 24 years earlier, can affect heart function. Alberico consulted a cardiologist who found that he was on the verge of heart failure."I never had any symptoms," said Alberico. "I would have been dead two or three times over incidents like that.""Once you're finished with the oncologist and you're sent back to a family doctor, it's a time bomb," said Alberico, an artist and active advocate for cancer survivors.A survey of 1,072 primary care doctors (PCP), which include internists and family practitioners, showed that 94 percent of them were unaware of the long-term side effects of four of the most commonly used chemotherapy drugs used to treat breast and prostate cancer.The findings were presented at the American Society of Clinical Oncology meeting in Chicago this past weekend.Heart problems, such as those Alberico experienced, are common long-term side effects of chemotherapy drugs. Others include osteoporosis, nerve damage, early menopause, infertility, leukemia, and the recurrence of cancer."We are creating more and more survivors and we owe it to them to make sure they have good subsequent care," Dr Michael Link, a pediatric oncologist and former ASCO president. "It is an emerging problem, but it's a good problem in some ways because people are surviving."
ORGANIZED COMMUNICATIONBetter treatments and an aging population are expected to fuel this trend in the coming years. At the same time, many health insurance plans will only cover oncology visits for a limited period of time, eventually pushing patients back to family doctors or internists."Passing off patients in this way is fine if there has been communication between the oncologist and the PCP," said Dr Otis Brawley, Chief Medical Officer of the American Cancer Society.That means having the oncologist tell the PCP what the patient was treated with, what the potential long-term side effects might be and what to look out for. But it often does not happen. "An oncologist cannot bill for that," Brawley added."The thing I'm most worried about is the transitioning of the pediatric survivor of cancer into adult cancer life," he said.The survey results also showed that about a third of the oncologists surveyed were unable to identify long-term side effects that occur after chemotherapy."Oncologists didn't know as much as one would think either. That was surprising," said Dr Larissa Nekhlyudov, a general internist who is the director of Cancer Research in the Department of Population Medicine at Harvard Medical School and lead author of the study."When people attack primary care physicians, I remind them that it wasn't long ago when oncologists didn't think about survivorship either," Nekhlyudov said.She said her aim was to highlight a growing problem, and the need to shift from a traditional approach of care that solely focused on acute treatment and getting the patient into remission to helping doctors recognize the long-term side effects and help patients cope. Sharing information is becoming all the more crucial as dozens of new cancer drugs reach the market, each with their own risk profile."There's no way a PCP can know all the late effects of these drugs. There's too much and they keep changing," Nekhlyudov said. "This will become more important as a discipline of study. This needs to be taught in medical schools. There's some movement, but very little."Dr Carol Rosenberg, director of Living in the Future (LIFE) Cancer Survivorship Program at NorthShore University HealthSystem in suburban Chicago, said she recently obtained a grant for a pilot program teaching residents and interns about the long-term effects of cancer treatment."If a 50-year-old woman came to the hospital with shortness of breath and had a history of breast cancer, there are a lot of (doctors) who would not know that the drugs could have caused cardiac issues," she said."If it wasn't taught to them in medical school, how would they know?" Rosenberg asked.(Reporting by Debra Sherman; Editing by Michele Gershberg and Cynthia Osterman) Reuters Health
Enzon Presents Final Analysis of Phase II PEG-SN38 (EZN-2208) Study in Patients With Metastatic Breast Cancer at 2012 ASCO Meeting
5 Jun 2012 WDM Group PR Network PISCATAWAY, NJ--(Marketwire - June 4, 2012) - Enzon Pharmaceuticals, Inc. (NASDAQ: ENZN) today presented data from the final analysis of a Phase II study in which PEG-SN38 demonstrated notable activity in patients with previously treated metastatic breast cancer. The data were presented in a poster session (Poster #1017) at the American Society of Clinical Oncology Meeting in Chicago, IL."Despite existing therapies, new and effective treatment options for patients with previously treated metastatic breast cancer are needed," said Joyce A. O'Shaughnessy, MD, a breast cancer specialist at Texas Oncology, Baylor Sammons Cancer Center, and US Oncology, and the principal investigator of the study. "In this study, PEG-SN38 resulted in a significant overall response rate in previously treated patients, as well as in triple negative breast cancer and platinum-resistant patients. These findings provide further clinical evidence indicating the potential of PEG-SN38 to deliver meaningful therapeutic benefit in patients with breast cancer."The study was designed to evaluate the efficacy of single-agent PEG-SN38 in 164 female patients who had previously been treated for metastatic breast cancer with either anthracycline and taxane (AT, up to 2 prior lines of therapy) (n=81), or anthracycline, taxane and capecitabine (ATX, up to 4 prior lines of therapy) (n=83). The primary objective of the study was to determine overall response; secondary objectives included duration of response, progression-free survival (PFS), overall survival (OS) and safety.Overall response was found to be meaningful in both the AT group (25%) and the ATX group (11%). For the AT and ATX cohorts, the response rate and clinical benefit rate among estrogen response positive patients were 15% and 39% (n= 92), respectively. In patients who progressed during or within 30 days of prior platinum-containing regimens, the clinical benefit rate was 18% (n=40). Among triple negative breast cancer patients, the response rate and clinical benefit rate were 23% (n=47) and 32% (n=47), respectively. For triple negative breast cancer patients with prior platinum-containing regimens, the clinical benefit rate was 18% (n=22). PEG-SN38 was generally well tolerated in these heavily pretreated patients, with neutropenia, diarrhea and leukopenia being the most common adverse events. Investigators concluded that PEG-SN38 warrants further clinical study in metastatic breast cancer. Enzon does not intend to pursue development of PEG-SN38 in this indication or in other malignancies on its own, absent a partner. Zhejiang Hisun Pharmaceuticals Co. Ltd recently acquired exclusive development and commercialization rights to PEG-SN38 in China. Enzon is seeking strategic partners for PEG-SN38 in other territories.

Afatinib* as first line efficacy in EGFR mutations lung CA !!
About LUX-Lung 3 Trial LUX-Lung 3 is a large, randomized, open-label, Phase III registration study comparing afatinib* to two chemotherapy agents, pemetrexed and cisplatin, as first-line treatment for patients with stage IIIb or IV NSCLC harboring an EGFR mutation. The study included 345 patients with EGFR mutation positive NSCLC globally. LUX-Lung 3 is the largest trial to date in patients with EGFR mutation positive NSCLC and the first study in this population to use pemetrexed / cisplatin as a comparator.(1) The most common drug-related adverse events observed in the afatinib* treatment arm were diarrhea (95%), rash (62%), and paronychia (57%). The most common drug-related adverse events observed in the chemotherapy arm (pemetrexed /cisplatin) were nausea (66%), decreased appetite (53%), and vomiting (42%). There was a low discontinuation rate associated with treatment-related adverse events in the trial (8% discontinuation rate for afatinib; 12% for chemotherapy). One percent of patients in the afatinib* arm discontinued due to diarrhea.
About Lung Cancer Lung cancer is the most common and most deadly form of cancer in the world: it accounts for 1.6 million new cancer cases annually. Because of its poor prognosis, 1.38 million deaths each year are attributable to lung cancer.(3) Overall, lung cancer is the cause of 18% of all cancer deaths.(3) Thirteen percent of all new cases of cancer are lung cancers(4)and smoking is attributed as the main cause.(5) Early testing for EGFR mutation status of lung cancer patients is critical in improving patient outcomes. Between 10-15% of Caucasian and 40% of Asian NSCLC patients have EGFR mutations, with 90% of these a result of two mutations (del19 or L858R).(2)
About Afatinib* Afatinib* is an irreversible ErbB Family Blocker which inhibits signal transduction of all kinase receptors from the ErbB Family(2), which is known to play a critical role in the growth and spread of the most pervasive cancers and cancers associated with high mortality (lung, breast, and head & neck cancers). Afatinib* is currently also in Phase III clinical development in breast cancer and head and neck cancer.

龍燈..農業生技數據保護策略!
F-龍燈董座:每年營收維持逾2成成長 3年內衝破150億元 2012/6/4 鉅亨網國內首檔農業生技股F-龍燈(4141),董事長羅昌庚樂觀指出,未來每年營收將維持2成以上穩定成長,3年後營收將上看150億元,並將透過種子基金布局,並同時啟動公司黃金10年。 F-龍燈主要產品為作物保護劑及植物營養劑,羅昌庚強調,同樣東西在歐洲賣55元,但在中國卻賣11元,靠的是利用全球的資源,及「環球農業」的佈局開花結果,加上集團內JRB氟化瓶的包材優勢,解決作物保護劑遠地配成本,因此毛利比同業高,成為全球少數可以源頭材料集中生產並共同享數據研發成果的「環球」農業生技廠。 羅昌庚指出,目前F-龍燈在全球60國取得超過700張藥證,且每年維持100-130張新增藥證的速度,擴大產品線。他解釋,相較於人用藥品,作物保護劑的藥證數據需依適用作物及蟲類,分門別類,因此因應藥證取得,該公司已完成超過9900個實驗,未來除每年維持新增藥證外,也將增加既有藥證新適用作物或蟲類,擴大單張藥證的含金量。 羅昌庚進一步解釋,不同西藥的專利保護,植物保護劑強調是「數據保護」,因作物保護劑的內容屬於不純物,原廠不會公布化學配方,有意切入的學名藥廠進行化學等同性分析時,必須有足夠的試驗數據證明與原廠配方吻合或是更好,否則就很難取得註冊登記,特別是作物保護劑的受體不像西藥統一,更添研究數據的難度,因此業界常說,農化註冊登記的法規障礙相當高,僅次於民用航空業。 羅昌庚自豪表示,植物保護劑學名廠怕的不是專利,而是數據,一般而言,原廠原始數據保護是十年起跳,因此即便原廠專利到期,還是可以透過不斷試驗的新數據延後對手新品上市的時間,這也讓植物保護劑學名廠切入的難度更高於西藥。如果沒有能力進行獨立數據產生及分析的廠商,一則只能選擇非歐美及巴西的二級市場,一則與原廠購買數據,並限用原廠保護劑的主要成分,僅添加其他非主要成分,賺取微薄的利潤,因此為何龍燈可以維持高獲利的原因在此。

信邦制药重磅新药将迎药监局“大考”
发布时间:2012/6/6 来源:药品资讯网信息中心 高考临近之际,信邦制药备受关注的皂苷_Rd注射剂也将迎来药监局药品审评中心的"大考",该研发产品终于进入了关键的技术审评阶段。如若皂苷_Rd注射剂审评通过,其未来市场价值颇为可观。 信邦制药今日公告,接到公司全资子公司贵州信邦远东药业有限公司的通知,国家药监局药品审评中心将于6月13日至15日召开人参皂苷_Rd注射剂药品审评咨询会议,会议将召集专家对该品种技术审评,对药学、临床、药理毒理等技术问题进行咨询。药审中心将依据技术审评意见、样品生产现场检查报告和样品检验结果,形成综合意见,连同有关资料报送国家药监局。药监局依据综合意见,作出审批决定。符合规定的,发给新药证书,申请人已持有《药品生产许可证》并具备生产条件的,同时发给药品批准文号;不符合规定的,发给《审批意见通知件》,并说明理由。 上述情况意味着,皂苷_Rd注射剂在被贵州省药监局初审后,即将迎来第二关技术审评,该审评将最终决定该新药能否早日获"准生证"并投产推广。 据了解,人参皂苷_Rd为国家中药一类新药,是从中药材三七中经多步分离提取的一种单体化合物。更重要的,该药是目前为止唯一报道的具有特异性阻断受体依赖性钙离子通道的化合物。近期的基础研究显示,该药还具有抑制谷氨酸释放、调节NO、抗氧化以及保护线粒体的多重作用,其主要用于急性缺血性脑卒中风的治疗,对脑缺血有明显保护和治疗作用,能明显降低脑卒中自发性高血压的中风率和死亡率。 信邦制药上市后,一类新药人参皂苷-Rd及人参皂苷-Rd注射剂的申报就成为公司头等大事。2010年9月21日该药的申报资料被贵州省药监局受理,当时被视为该项目的一个进展。2012年3月30日,信邦制药披露接到承担公司国家一类新药人参皂苷_Rd临床研究组长单位第四军医大学西京医院通知,由该医院牵头完成的"人参皂苷_Rd注射液治疗急性脑梗死的随机、双盲、安慰剂对照的多中心Ⅲ期临床试验"的研究论文已在线发表于国际专业杂志《European Journal of Neurology》(《欧洲神经病学》)。 根据《药品注册管理办法》规定,在省级药监局初审后的第二个阶段,即技术审评及生产现场检查阶段由国家药监局审评中心主导,审核时限为120天。符合审批规定后,药品进入审批阶段,该阶段也由国家药监局主导,时限20天,符合规定的,发给新药证书。最后进入生产线通过GMP认证阶段,该阶段由国家药监局主导,时限100个工作日。 业内人士分析,如若皂苷_Rd注射剂审评通过,其未来市场价值颇为可观。我国是脑血管病患者高发的国家,其发病率和死亡率位居前列,相关药物市场容量巨大。在这一领域,化学药并不占优势,反而是中药特别是中药注射剂占据了重要位置。公司人参皂苷-Rd投产后,凭借植物单体药物身份和公司在心脑血管领域的营销优势,市场前景将颇为乐观。
日本用小分子RNA治疗脊髓延髓肌萎缩症获进展
发布时间:2012/6/6 来源:药品资讯网信息中心 日本名古屋大学和自治医科大学的研究小组在新一期《自然·医学》期刊网络版上报告说,他们在老鼠实验中发现一种用小分子RNA(核糖核酸)遏制脊髓延髓肌萎缩症的新疗法。 脊髓延髓肌萎缩症是引发全身肌无力的神经变性疾病,很难治疗,患者年龄常在30岁至60岁之间。神经变性疾病由神经细胞内积聚的异常蛋白质所致,异常雄性激素受体蛋白质被认为是导致该病的原因。 研究小组分析老鼠基因时发现,参与合成异常雄性激素受体蛋白质的异常信使RNA与名为"CELF2"的蛋白质结合后,前者就会保持稳定,最终造成老鼠运动机能减退。但是一种名为"196a"负责调节基因表达的小分子RNA能遏制"CELF2"蛋白质的表达,从而导致异常信使RNA的稳定性下降并分解,异常雄性激素受体蛋白质的总量也随之减少。 研究小组给患有脊髓延髓肌萎缩症的老鼠注射名为"196a"的小分子RNA后,其神经细胞内的异常雄性激素受体蛋白质减少了约60%,老鼠的运动机能得以维持。 研究小组负责人、名古屋大学教授祖父江元说:"这是从根本上遏制(脊髓延髓肌萎缩症)病情的治疗方法。"研究小组认为,此类疗法还有望用于阿尔茨海默氏症、帕金森氏症、肌萎缩侧索硬化症等神经变性疾病的治疗。
骨髓移植 奇美醫院年底成軍投入
自由時報-2012年06月06日 〔自由時報記者孟慶慈/台南報導〕骨髓移植是血液性惡性疾病治療的最後希望,雲嘉南地區現僅成大醫院從事自體、異體骨髓移植治療,很多患者需到北部求醫,奇美醫院年底將成立完整的骨髓移植團隊,投入相關治療行列,目前正積極訓練團隊成員。奇美醫院血液腫瘤科醫師吳鴻昌表示,骨髓移植是治癒嚴重再生不良性貧血、血癌、淋巴癌、先天性免疫缺損等疾病的最後希望;奇美醫院今年光是血液腫瘤科就有四名需移植的病患。吳鴻昌表示,雖然骨髓移植後感染、排斥的風險都很高,但骨髓移植是治療血液性惡性疾病唯一的希望,不到最後關頭不會提出,因此更需要完整的醫療團隊來照顧患者,所幸目前醫學精進,患者的存活率已大為提高。吳鴻昌指出,骨髓的捐贈者或來自親屬,或是一般的捐贈者,早期取捐贈者的骨髓必須進開刀房,全身麻醉,在髖骨位置穿數十針抽取骨髓。如今醫學進步,捐髓者只需事先服用白血球生長激素,讓幹細胞進入靜脈,只要挨一針就能收集到一袋血液幹細胞,對捐髓者來說輕鬆許多。吳鴻昌表示,奇美醫院八年前曾經為數名病患做過骨髓移植,但因故中止,現今重新整軍啟動,相關醫師已到外院接受訓練,他自己已在台大受訓一年,接下來是護理師、藥師等訓練,預定年底骨髓移植團隊正式成立。
