PG2 Concurrent With Chemoradiation for Locally Advanced Esophageal Cancer

The primary objective of this study is to evaluate the efficacy of PG2 concurrent with concurrent chemoradiation therapy (CCRT) for relieving fatigue among locally advanced esophageal cancer patients who are under preoperative chemoradiation therapy at curative setting. This study will be designed to compare the fatigue status between two study arms patients under CCRT.
The secondary objective is to assess the efficacy of PG2 to improve the quality of life of patient during CCRT. Also, the investigators try to determine the effect of PG2 on tumor response post CCRT, disease free survival (DFS) and overall survival (OS) of patients by comparing the above outcome between the two study arms.
The mechanism of immunomodulatory of PG2 and tumor response, DFS and OS for patients with esophageal cancer treated with preoperative CCRT concurrent with or without PG2 will be investigated in add-on study.

The objective of this study was to evaluate the impact of early progesterone removal on pregnancy rates to fixed-time artificial insemination (FTAI) in presynchronized beef cows. Postpartum beef cows (n = 882) were randomly assigned to 1 of 2 treatments: 1) 7&7 Synch: cows received a controlled internal drug release insert (CIDR) and a 25-mg injection of prostaglandin F_2α on day 0, 100 μg of GnRH on day 7, a second injection of prostaglandin F_2α (PG2) at CIDR removal on day 14, and a second injection of GnRH at FTAI 60-66 h after PG2 (day 17); 2) 7&6 Synch: cows received the same treatment as 7&7 Synch; however, CIDR removal occurred in conjunction with PG2 on day 13, while FTAI remained at 60-66 h after CIDR removal (day 16). Ovarian ultrasonography was performed to determine follicle diameter at PG2 and FTAI in a subset of cows (n = 40). Cows exposed to the 7&7 Synch tended to have larger follicle diameter at PG2 compared with 7&6 Synch cows (P = 0.09); however, there were no differences in follicle diameter at FTAI. No differences were determined between treatments for the expression of estrus (7&7 Synch: 61.6 ± 5.30; 7&6 Synch: 54.1 ± 5.45; P = 0.31) or pregnancy rates to FTAI (7&7 Synch: 60.8 ± 3.83; 7&6 Synch: 57.0 ± 3.84; P = 0.42). In conclusion, early removal of progesterone did not impact pregnancy rates in presynchronized beef cows.

Dendronized Polymer‐Derived Nanomedicines for Mitochondrial Dynamics Regulation and Immune Modulation

Article

Author: Hou, Xingyu ; Gong, Qiyong ; Luo, Kui ; Zhong, Dan ; Pan, Dayi

AbstractThe effects of dendron side chains in polymeric conjugates on tumor penetration and antigen presentation are systematically examined. Three polymer‐gemcitabine (Gem) conjugates (pG0‐Gem, pG1‐Gem, pG2‐Gem) are designed and prepared. The pG2‐Gem conjugate uniquely binds to the mitochondria of tumor cells, thus regulating mitochondrial dynamics. The interaction between the pG2‐Gem conjugate and the mitochondria promotes great penetration and accumulation of the conjugate at the tumor site, resulting in pronounced antitumor effects in an animal model. Such encouraging therapeutic effects can be ascribed to immune modulation since MHC‐1 antigen presentation is significantly enhanced due to mitochondrial fusion and mitochondrial metabolism alteration after pG2‐Gem treatment. Crucially, the drug‐free dendronized polymer, pG2, is identified to regulate mitochondrial dynamics, and the regulation is independent of the conjugated Gem. Furthermore, the combination of pG2‐Gem with anti‐PD‐1 antibody results in a remarkable tumor clearance rate of 87.5% and a prolonged survival rate of over 150 days, demonstrating the potential of dendronized polymers as an innovative nanoplatform for metabolic modulation and synergistic tumor immunotherapy.

Complementary and alternative medicine: A narrative review of nutritional approaches for cancer-related fatigue

Review

Author: Liu, Jimin ; Zhang, Dong ; Zhang, Yue ; Li, Meng

Cancer-related fatigue (CRF) is a common symptom among patients with cancer, with a prevalence of >49%. CRF significantly affects the quality of life of patients and may also affect their overall survival. Pharmacological interventions serve as a last resort after carefully weighing the risks and benefits, with limited benefits for patients, many side effects, and adverse reactions. Compared to traditional medicine, nutritional approaches have fewer side effects, are highly accepted by patients, and do not affect the antitumor treatment of patients. Many studies have shown that nutritional approaches, as a form of complementary and alternative medicine, help improve the symptoms of CRF and the quality of life of patients. This study was designed to examine nutritional approaches to CRF and assess their effectiveness of nutritional approaches in improving CRF. We present an overview of clinical trials investigating nutritional approaches for CRF that have been published over the last 2 decades. A total of 33 records were obtained from 3 databases: Web of Science, MEDLINE, and PubMed. Some nutritional approaches, such as melatonin, PG2, and S-adenosyl-l-methionine, are potential options for CRF treatment. However, the trials included in the review varied widely in quality, most were weak in methodology, and there is currently insufficient evidence to conclude with certainty the effectiveness of nutritional approaches in reducing CRF. Therefore, the design and methods used in future complementary and alternative medicine trials should be more rigorous.

PhytoHealth Corporation announced a new clinical study results published at 2024 ESMO Congress: PG2 plus preoperative chemoradiotherapy improves survival in patients with locally advanced esophageal cancer

TAIPEI and BARCELONA, Spain, Sept. 16, 2024 /PRNewswire/ -- A groundbreaking study conducted by PhytoHealth Corporation, a leading provider of botanical medicine, has revealed that combining Astragalus Polysaccharides (PG2®Lyo. Injection) with standard concurrent chemoradiotherapy (CCRT) significantly improves survival rates for patients with advanced esophageal cancer. The study enrolled 38 patients with stage IIb to IIIb esophageal cancer. Participants were randomly assigned to receive either CCRT alone or CCRT combined with PG2, a proprietary extract of Astragalus membranaceus roots developed by PhytoHealth Corporation. Results showed that patients who received PG2 in addition to CCRT experienced significantly longer overall survival compared to those who received CCRT alone. Furthermore, the combination therapy resulted in a higher tumor objective response rate. The study also found that PG2 helped strengthen the immune system by modulating the tumor immune microenvironment (TIME) and enhancing the suppression of tumor growth. 'These findings offer a new hope for patients with esophageal cancer,'' said Dr. Wen-Chieh Huang, Chief of Division of Thoracic Surgery at Mackay Memorial Hospital, Taiwan and the Principal Investigator of the clinical trial for PG2, a drug for cancer-related fatigue (CRF) relief developed by PhytoHealth Corporation, Taiwan. "PG2 has the potential to become a valuable addition to the standard treatment regimen, and can achieve improved patient outcomes.'' The data will be presented as a poster at the prestigious 2024 ESMO Congress. [ESMO abstract link]. Dr. Huang noted that treatment options for esophageal cancer patients are relatively limited compared to those for other cancers. However, this study has shown that PG2 combination therapy can reduce inflammation markers in the blood, decrease the differentiation of macrophages towards the M2 type, and even help shrink tumors while improving survival rates. This represents a significant breakthrough in the treatment of esophageal cancer. Dr. Huang further added that esophageal cancer patients often face tremendous challenges during treatment, with many unable to complete their therapy. However, by incorporating CRF medication, most patients were able to regain their strength, complete the full courses of cancer treatment, and achieve the expected therapeutic effects. Esophageal cancer is a challenging disease with high recurrence rates and poor survival outcomes. PG2, previously established as a treatment for cancer-related fatigue (already approved by Taiwan Food and Drug Administration) has shown promise as a potential treatment enhancer. This latest discovery marks a significant advancement in the ongoing battle against this challenging cancer.
