A Phase I Study to Evaluate the Safety of the Herbal Medicine SH003 in Patients With Solid Cancer.

ABSTRACT: Background: Cancer is a major health problem worldwide and the leading cause of death in many countries. Preclinical studies have shown the therapeutic anticancer effects of SH003, a novel herbal medicine containing Astragalus membranaceus, Angelica gigas, and Trichosanthes kirilowii. The present study investigated the maximum tolerated dose of SH003 in patients with solid cancers. Methods: This open-label, dose-escalation trial used the traditional 3 + 3 dose-escalation design. Patients with solid cancers were recruited and administered 1 to 4 tablets of SH003 thrice daily for 3 weeks according to the dose level. Adverse events were evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE). Dose-limiting toxicities (DLTs) were defined as Grade 3 or higher adverse events based on CTCAE. The maximum tolerated dose was defined as the highest dose at which no more than 1 of 6 patients experienced DLT. Results: The present study enrolled 11 patients. A total of 31 adverse events occurred. According to the CTCAE, all the observed adverse events were grade 2 or less and no adverse events of grade 3 or more corresponding to DLT occurred. Conclusion: The study results indicated that the maximum tolerated dose of SH003 was 4800 mg/day. A Phase 2 study is required to determine the efficacy of SH003 in patients with cancer at a dose of 4800 mg/day or less.

Project description:Lessons learnedPharmacokinetic results underscore that the vorolanib (X-82) study design was successful without the need for further dose escalation beyond 400 mg once daily (q.d.).Therefore, the recommended dose of X-82 as a single agent in patients with advanced cancer is 400 mg q.d.BackgroundVorolanib (X-82) is a novel, oral, multikinase vascular endothelial growth factor (VEGF) receptor/platelet-derived growth factor (PDGF) receptor inhibitor that was developed on the same chemical scaffold as sunitinib, but designed to improve upon the safety profile while maintaining the efficacy of sunitinib. By targeting the VEGF and PDGF receptors, X-82 was expected to disrupt tumor angiogenesis and be active in a broad spectrum of solid tumors. Therefore, we determined the maximum tolerated dose (MTD) and characterized the preliminary pharmacokinetics and clinical tumor response of X-82 as a single agent in patients with advanced solid tumors.MethodsAdult patients with advanced solid tumors received X-82 as tablets or capsules (once daily [q.d.] or b.i.d.) every 4 weeks. Patients were evaluated for response every 8 weeks, and continued treatment until disease progression or intolerable toxicity.ResultsFifty-two patients received study treatment in 17 cohorts. X-82 capsule dosing was as follows: cohorts 1-6 (20-400 mg q.d.) and cohorts 7-8 (140-200 mg b.i.d.). Patients in cohorts 9-17 received 50-800 mg q.d. tablet dosing. The median time on treatment was 58 days. X-82 blood pharmacokinetics appeared dose-independent with a t 1/2 of 5.13 hours and 6.48 hours for capsule and tablet formulations, respectively. No apparent accumulation was observed after 21 days of daily dosing.ConclusionX-82 had a safety profile consistent with its mechanism of action. It has a short half-life and was well tolerated by most patients. Study enrollment ended prior to the determination of the MTD because of the apparent saturation of absorption at 400-800 mg. The recommended dose of X-82 as a single agent in patients with advanced cancer is 400 mg q.d.

Project description:Cardiovascular diseases (CVDs) are a significant health burden with an ever-increasing prevalence. They remain the leading causes of morbidity and mortality worldwide. The use of medicinal herbs continues to be an alternative treatment approach for several diseases including CVDs. Currently, there is an unprecedented drive for the use of herbal preparations in modern medicinal systems. This drive is powered by several aspects, prime among which are their cost-effective therapeutic promise compared to standard modern therapies and the general belief that they are safe. Nonetheless, the claimed safety of herbal preparations yet remains to be properly tested. Consequently, public awareness should be raised regarding medicinal herbs safety, toxicity, potentially life-threatening adverse effects, and possible herb-drug interactions. Over the years, laboratory data have shown that medicinal herbs may have therapeutic value in CVDs as they can interfere with several CVD risk factors. Accordingly, there have been many attempts to move studies on medicinal herbs from the bench to the bedside, in order to effectively employ herbs in CVD treatments. In this review, we introduce CVDs and their risk factors. Then we overview the use of herbs for disease treatment in general and CVDs in particular. Further, data on the ethnopharmacological therapeutic potentials and medicinal properties against CVDs of four widely used plants, namely Ginseng, Ginkgo biloba, Ganoderma lucidum, and Gynostemma pentaphyllum, are gathered and reviewed. In particular, the employment of these four plants in the context of CVDs, such as myocardial infarction, hypertension, peripheral vascular diseases, coronary heart disease, cardiomyopathies, and dyslipidemias has been reviewed, analyzed, and critically discussed. We also endeavor to document the recent studies aimed to dissect the cellular and molecular cardio-protective mechanisms of the four plants, using recently reported in vitro and in vivo studies. Finally, we reviewed and reported the results of the recent clinical trials that have been conducted using these four medicinal herbs with special emphasis on their efficacy, safety, and toxicity.

Project description:RationaleThe highest burden of liver cancer occurs in developing countries, where the use of herbal medicine (HM) is still widespread. Despite this trend, few studies have been conducted to report HM practices of patients with a hepatic tumor in the developing world. Hence, this study aimed to document the use of HM among patients with liver cancer in Peru.Study design and methodsA comparative behavioral epidemiological survey was conducted among liver cancer patients attending the National Cancer Institute of Peru. Information was obtained by direct interviews based on a semistructured questionnaire. The use of HM in Peruvian liver cancer patients was reported, first, regarding general consumption prior to the onset of disease, and second, after the appearance of symptoms that patients would relate to their tumor. In parallel, general consumption of HM in noncancerous people was assessed as a comparative figure. A correspondence analysis was performed to reveal potential associations between the symptoms of cancer and the specific use of HM.ResultsEighty-eight patients and 117 noncancerous individuals participated in the survey. Overall, 68.3% of the people interviewed claimed to use HM on a regular basis for general health preservation. Furthermore, 56.8% of the patients turned to plants first to treat the disorders for which they later came to the cancer care center. When compared with the number of plant species used routinely (n = 78), a selection of plants was made by patients in response to the symptoms of cancer (n = 46). At least 2 plant species, Aloe vera and Morinda citrifolia, were significantly associated with the treatment of liver cancer-related symptoms in the patient group.ConclusionsThe present study is the first survey on the HM practices of patients with liver cancer in Latin America and, more broadly, in the developing world. Our findings confirm that HM remains one of the principal primary health care resources in Peru, even for a severe disease like liver cancer. These traditional, complementary and alternative medicine practices should be taken into consideration in Peruvian health programs aiming to educate the population in cancer prevention and treatment, as well as integrative cancer management.

Project description:BACKGROUND:Human telomerase reverse transcriptase (hTERT) is an antigen that may represent a target for a novel anti-cancer strategy. A pilot, phase I study tested the safety and feasibility of a prime-boost immunization regimen based on V935, an adenoviral type 6 vector vaccine expressing a modified version of hTERT, administered alone or in combination with V934, a DNA plasmid that also expresses the same antigen and is delivered using the electroporation injection technique. METHODS:Treatments: Group #1 received two doses (low-dose: 0.5?×?109 vg, and high-dose: 0.5?×?1011 vg) of V935 followed by a 4-week observation period. Group #2 received three doses of V934-electroporation and two doses of V935 following a 4-week observation period. Doses were low-dose V934 (0.25 mg of plasmid) with low-dose V935 (0.5?×?109 vg); high-dose V934 (2.5 mg of plasmid) with high-dose V935 (0.5?×?1011 vg). Group #3 received five doses of V934-EP and two doses of V935: V934 was administered IM every 2 weeks for five doses. Following a 4-week observation period, V935 was administered IM every 2 weeks for two doses followed by a 4-week observation period. One (1) dose level was tested in treatment group #3: high-dose V934 (2.5 mg of plasmid), in combination with high-dose V935 (0.5?×?1011 vg). Immunogenicity was measured by ELISPOT assay and three pools of peptides encompassing the sequence of hTERT. RESULTS:In total, 37 patients affected by solid tumors (prostate cancer in 38%) were enrolled. The safety profile of different regimens was good and comparable across groups, with no severe adverse events, dose-limiting toxicities or treatment discontinuations. As expected, the most common adverse events were local reactions. A significant increase in ELISPOT responses against hTERT peptide pool 2 was observed (p?<?0.01), while no evidence of boosting was observed for peptide pools 1 and 3. This was also evident for group #1 and #2 separately. In patients with prostate cancer, there was a significant increase in ELISPOT response against hTERT peptide pool 2 following immunization (p?<?0.01), regardless of previous therapy, immunosuppressing agents, or adenoviral type 6 titers at screening. CONCLUSION:Our results suggest the safety and feasibility of V934/V935 hTERT vaccination in cancer patients with solid tumors Trial Registration Name of the registry: ClinicalTrial.gov Trial registration number: NCT00753415 Date of registration: 16 September 2008 Retrospectively registered URL of trial registry record: https://clinicaltrials.gov/ct2/results?cond=&term=NCT00753415&cntry=&state=&city=&dist=.
