Salarius Pharmaceuticals Receives FDA Clearance of SP-3164 Investigational New Drug Application to Begin a Phase 1 Clinical Trial in Relapsed/Refractory Non-Hodgkin Lymphoma Patients
The trial will assess the safety and preliminary efficacy of Salarius’ novel targeted protein degrader SP-3164; Patient dosing expected to begin in 2H 2023
The trial will also assess the utility of a gene signature to identify patients that are potentially sensitized to SP-3164 treatment and may be more likely to respond
“FDA clearance of the SP-3164 IND marks another significant milestone for Salarius and demonstrates our continued focus and commitment to bringing new therapies to patients in need of new treatment options,” said
According to the
During the trial, Salarius will be assessing the applicability of the gene signature in predicting response to SP-3164. Previous research with similar agents indicates that patients with an identifiable gene signature may be more likely to respond to SP-3164 treatment.
“First generation targeted protein degraders (TPD) have generated a great deal of enthusiasm within the pharmaceutical and medical communities, with first-generation TPD’s such as Revlimid® and Pomalyst® together generating more than
SP-3164 is an oral, next-generation molecular glue that uses Salarius’ deuterium-enabled chiral switching platform to stabilize the preferred (S)-enantiomer of avadomide, an extensively studied clinical compound that has demonstrated encouraging single-agent and combination-therapy clinical efficacy in NHL and other hematologic malignancies. The addition of deuterium at the chiral center of the molecule prevents conversion to the unwanted (R)-enantiomer, allowing for isolation and development of the preferred (S)-enantiomer into a potential new cancer treatment.
As such, SP-3164 is a new chemical entity and has been issued a composition-of-matter patent in the
Seclidemstat has received fast track, orphan drug and rare pediatric disease designations for Ewing sarcoma from the FDA and is currently in a Phase 1/2 clinical trial for relapsed/refractory Ewing sarcoma. Salarius is also exploring seclidemstat’s potential in several cancers with high unmet medical need, with an investigator-initiated Phase 1/2 clinical trial in hematologic cancers at
