The US Food and Drug Administration (FDA) has lifted the partial clinical hold on trials of selinexor (KPT-330) in patients with hematologic malignancies.
The partial hold, which was announced on March 10, was placed on all trials of the drug, including those in patients with solid tumor malignancies.
The hold meant that no new patients could be enrolled in selinexor trials.
Patients who were already enrolled and had stable disease or better could remain on selinexor therapy.
Now, the FDA has lifted the hold on trials of patients with hematologic malignancies, so new patients can be enrolled in these trials and begin receiving selinexor.
The FDA had placed the hold due to a lack of information in the investigator’s brochure, including an incomplete list of serious adverse events associated with selinexor.
Karyopharm Therapeutics Inc., the company developing selinexor, noted that the hold was not the result of patient deaths or any new information regarding the safety profile of selinexor.
In response to the hold, Karyopharm amended the investigator’s brochure, updated informed consent documents, and submitted the documents to the FDA.
“The Karyopharm team worked diligently to update and submit the required documents to the FDA, which allowed the hematology division to expeditiously remove the partial clinical hold,” said Michael G. Kauffman, MD, PhD, chief executive officer of Karyopharm.
“We anticipate that the solid tumor divisions will follow suit shortly. Patient enrollment is again underway in our hematologic oncology studies. Our previously disclosed enrollment rates and timelines for both ongoing and planned trials are not expected to be materially impacted.”
About selinexor
Selinexor is a first-in-class, oral, selective inhibitor of nuclear export compound. The drug functions by inhibiting the nuclear export protein XPO1 (also called CRM1).
This leads to the accumulation of tumor suppressor proteins in the cell nucleus, which subsequently reinitiates and amplifies their tumor suppressor function. This is thought to prompt apoptosis in cancer cells while largely sparing normal cells.
To date, more than 1900 patients have been treated with selinexor.
The drug is currently being evaluated in clinical trials across multiple cancer indications, including in acute myeloid leukemia (SOPRA), in multiple myeloma in combination with low-dose dexamethasone (STORM) and backbone therapies (STOMP), as well as in diffuse large B-cell lymphoma (SADAL).
