Geron Corp. operates as a biotechnology company. The company is headquartered in Menlo Park, California and currently employs 17 full-time employees. The firm is engaged in the development of therapeutic products for oncology. Using its nucleic acid chemistry, Geron designed Imetelstat to be an oligonucleotide that binds with high affinity to the ribonucleic acid (RNA) template of telomerase, thereby directly inhibiting telomerase activity. Janssen is engaged in the development of Imetelstat with two clinical trials, such as a Phase II trial in myelofibrosis (MF), referred to as IMbark, and a Phase II/III trial in myelodysplastic syndromes (MDS) referred to as IMerge. Imetelstat is a lipid conjugated 13-mer oligonucleotide that is designed to be complementary to and bind with high affinity to the RNA template of telomerase, thereby directly inhibiting telomerase activity.
