Blood and Lymphatic Cancer : Targets and Therapy
|August 16, 2019
Summary
Targeted therapies like isocitrate dehydrogenase 1 (IDH1) inhibitors offer new hope for relapsed or refractory acute myeloid leukemia (R/R AML) patients. These agents show promising outcomes and manageable safety profiles in clinical studies.
Area of Science:
- Hematology
- Oncology
- Molecular Biology
Background:
- Relapsed or refractory acute myeloid leukemia (R/R AML) presents a significant clinical challenge with poor prognoses.
- Isocitrate dehydrogenase 1 (IDH1) mutations occur in 7-14% of AML patients, representing a targetable pathway.
Purpose of the Study:
- To systematically review clinical outcomes and safety of IDH1 inhibitors and other agents in adult IDH1-mutated R/R AML.
- To evaluate the efficacy of targeted therapies in a difficult-to-treat AML population.
Main Methods:
- Systematic literature review of clinical trials and studies involving IDH1 inhibitors in R/R AML.
- Analysis of reported complete remission (CR), overall response (OR), and overall survival (OS) data.
Main Results:
- Ivosidenib monotherapy demonstrated a 24% CR, 42% OR, and 9-month median OS in R/R AML.
- Other IDH1 inhibitors (IDH305, FT-2102) also showed promising results.
- IDH1 inhibitors were generally well-tolerated, with manageable toxicities like IDH-differentiation syndrome.
Conclusions:
- IDH1 inhibitors represent a promising targeted approach for IDH1-mutated R/R AML.
- Ongoing trials with other agents (venetoclax, PARP inhibitors, etc.) will further define the role of IDH1-targeted therapies in AML treatment strategies.

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

01:09Mutation, Gene Flow, and Genetic Drift
62.5K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

Mutations are heritable changes in an organism’s genome involving alterations in the base sequence of DNA or RNA. These changes can influence cellular processes and phenotypic traits, potentially transforming the unaltered wild type into a mutant form. Such changes, termed forward mutations, are pivotal in shaping the genetic diversity of organisms.RNA viruses exhibit the highest mutation rates due to the absence of robust proofreading mechanisms during genome replication. In contrast,...

Point mutations are genetic alterations involving the change of a single nucleotide base pair in DNA. Depending on how the alteration affects protein synthesis, they can lead to various consequences.Point mutations fall into the following types:Silent mutations occur when a nucleotide change does not alter the amino acid sequence due to the redundancy of the genetic code. For instance, changing ACC to ACA still encodes threonine, leaving the protein function unaffected. This occurs because...
