Mipsagargin (G-202), has orphan drug designation as a treatment during chemotherapy for HCC. It is a thapsigargin-based prodrug with cytotoxic activity used to reduce blood flow to the tumor during treatment. Results from Phase 2 trial recommended G-202 as a first-in-class  PSMA-targeted prodrug and that it move to clinical trials.Current research includes the search for the genes that are disregulated in HCC, antiheparanase antibodies, protein markers, non-coding RNAs (such as TUC338) and other predictive biomarkers. As similar research is yielding results in various other malignant diseases, it is hoped that identifying the aberrant genes and the resultant proteins could lead to the identification of pharmacological interventions for HCC.The development of three-dimensional culture methods provides a new approach for preclinical studies of cancer therapy using patient-derived organoids. These miniaturized organoid  avatars  of a patients tumor recapitulate several features of the original tumor, rendering them an attractive model for drug-sensitivity testing and precision medicine for HCC and other types of primary liver cancer.Furthermore, HCC occurs in patients with liver disease. A biomarker named six-miRNA signature allows effective treatment of patients with HCC and is able to predict its recurrence in the liver. Clinical
JX-594, an oncolytic virus, has orphan drug designation for this condition and is undergoing clinical trials. Hepcortespenlisimut-L (Hepko-V5), an oral cancer vaccine, also has US FDA orphan drug designation for HCC. Immunitor Inc. completed a Phase II trial, published in 2017. A randomized trial of people with advanced HCC showed no benefit for the combination of everolimus and pasireotide.
Renal osteodystrophy/adynamic bone disease is currently defined as an alteration of bone morphology in patients with chronic kidney disease (CKD). It is one measure of the skeletal component of the systemic disorder of chronic kidney disease-mineral and bone disorder (CKD-MBD). The term "renal osteodystrophy" was coined in 1943, 60 years after an association was identified between bone disease and kidney failure.The traditional types of renal osteodystrophy have been defined on the basis of turnover and mineralization as follows: 1) mild, slight increase in turnover and normal mineralization; 2) osteitis fibrosa, increased turnover and abnormal mineralization; 3) osteomalacia, decreased turnover and abnormal mineralization; 4) adynamic, decreased turnover and acellularity; and, 5) mixed, increased turnover with abnormal mineralization. A Kidney Disease: Improving Global Outcomes report has suggested that bone biopsies in patients with CKD should be characterized by determining bone turnover, mineralization, and volume (TMV system).On the other hand, CKD-MBD is defined as a systemic disorder of mineral and bone metabolism due to CKD manifested by either one or a combination of the following: 1) abnormalities of calcium, phosphorus, PTH, or vitamin D metabolism; 2) abnormalities in bone turnover, mineralization, volume, linear growth, or strength (renal osteodystrophy); and 3) vascular or other soft-tissue calcification.
