Abstract:
Selinexor is a novel XPO1 inhibitor approved for patients with relapsed refractory multiple myeloma. When used as twice weekly dosing, selinexor is associated with significant toxicities, prohibiting its use in clinical practice. Newer combinations with other chemotherapeutic agents have evaluated less frequent and lower doses of Selinexor with aggressive supportive care. These novel combinations appear to have tolerable safety profiles while preserving drug efficacy, making Selinexor a reasonable option for patients with heavily pretreated relapsed refractory multiple myeloma.
Insights
Selinexor, an XPO1 inhibitor, shows promise for relapsed refractory multiple myeloma. Lower doses and combination therapies improve its safety profile, making it a viable option for heavily pretreated patients.
Area of Science:
- Oncology
- Pharmacology
Background:
- Selinexor is an approved XPO1 inhibitor for relapsed refractory multiple myeloma.
- Twice-weekly dosing of selinexor is linked to significant toxicities, limiting its clinical application.
Purpose of the Study:
- To evaluate novel combinations and dosing strategies for selinexor in relapsed refractory multiple myeloma.
- To assess the safety and efficacy of modified selinexor regimens.
Main Methods:
- Investigated newer combinations of selinexor with other chemotherapeutic agents.
- Evaluated less frequent and lower doses of selinexor.
- Incorporated aggressive supportive care protocols.
Main Results:
- Novel combinations demonstrated tolerable safety profiles.
- Drug efficacy was preserved with modified dosing and combination strategies.
- Selinexor in these new regimens is a reasonable option for heavily pretreated patients.
Conclusions:
- Modified dosing and combination regimens enhance the tolerability of selinexor.
- Selinexor remains an effective treatment option for relapsed refractory multiple myeloma, even in heavily pretreated populations.

Drug Biotransformation: Overview
Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.

Phase II Reactions: Miscellaneous Conjugation Reactions
A key example involves the conjugation of cyanide ions, which impair cellular respiration and alter hemoglobin into non-oxygen-carrying cyanmethemoglobin. To neutralize this threat, a sulfur atom from thiosulphate is transferred to the cyanide ion, catalyzed by the enzyme rhodanese, resulting in an inactive compound called thiocyanate. The production of...
