An Open Label, Phase 1/1b Study to Evaluate the Safety, Pharmacokinetics, Pharmacodynamics and Clinical Activity of Imetelstat in Combination With Ruxolitinib in Patients With Myelofibrosis

Summary: The purpose of the study is to identify the recommended Part 2 dose (R2PD) of imetelstat sodium in combination with ruxolitinib in participants with myelofibrosis (MF) in Part 1, and to evaluate the safety and clinical activity of the R2PD of imetelstat sodium in combination with ruxolitinib or other Janus Kinase (JAK) inhibitors in participants with MF in Part 2.

A Phase 2 Trial Investigating Decitabine in Combination With a JAK-Inhibitor as a Bridge to Allogeneic Hematopoietic Stem Cell Transplant in Patients With Accelerated/Blast Phase Myeloproliferative Neoplasms

Summary: This phase II trial studies how well decitabine with ruxolitinib, fedratinib, or pacritinib works before hematopoietic stem cell transplant in treating patients with accelerated/blast phase myeloproliferative neoplasms (tumors). Drugs used in chemotherapy, such as decitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or b...

WARNING: ENCEPHALOPATHY INCLUDING WERNICKE'S
Serious and fatal encephalopathy, including Wernicke's, has occurred in patients treated with INREBIC. Wernicke's encephalopathy is a neurologic emergency. Assess thiamine levels in all patients prior to starting INREBIC. Do not start INREBIC in patients with thiamine deficiency; replete thiamine prior to treatment initiation. While on treatment all patients should receive prophylaxis with daily oral thiamine and should have thiamine levels assessed as clinically indicated. If encephalopathy is suspected, immediately discontinue INREBIC and initiate parenteral thiamine. Monitor until symptoms resolve or improve and thiamine levels normalize

4.1Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The data in the WARNINGS AND PRECAUTIONS Section 5.1 Encephalopathy, including Wernicke's, reflect exposure to INREBIC as a single agent in 608 patients who received more than one dose (ranging from 30 mg to 800 mg) in Studies JAKARTA, ARD11936, JAKARTA2, ARD12042, ARD12888, TED12037/TED12015, INT12497, and TES13519, of whom 459 were patients with myelofibrosis, including 97 patients previously treated with ruxolitinib. Among the 608 patients receiving INREBIC, the median drug exposure was 37 weeks and the median number of cycles initiated was 9 cycles. Fifty-nine percent of 608 patients were exposed for 6 months or longer and 39% were exposed for 12 months or longer.
Using the dataset described above, the most common adverse reactions in >20% of patients (N=608) were diarrhea, nausea, anemia, vomiting, fatigue, thrombocytopenia, and constipation.
4.2Postmarketing Experience
The following adverse reactions have been identified during post approval use of INREBIC. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Eye Disorders: Uveitis
