Summary
Brief summary (as posted)
Patients with multiple myeloma (a type of blood cancer affecting the white blood cells) or amyloidosis (abnormal buildup of a protein called amyloid in the body) are often given treatment with the drugs lenalidomide or pomalidomide. Some patients may experience an allergic reaction to these drugs which would mean stopping the treatment. The purpose of this research study is to see how safe and useful desensitization is in allowing patients to receive further treatment with lenalidomide or pomalidomide.

- description
- Participants will only receive lenalidomide if they had previously received this drug as a part of their treatment for multiple myeloma or amyloidosis and had experienced an allergic reaction to the drug. Participants will first be given a low dose of lenalidomide with increasing doses over 10-12 steps over 3.5 to 5 hours. Participants will be monitored for side effects or reactions prior to each dose step and any reactions will be managed before giving the increased dose at the next step. The final dose will be determined by the study doctor and is expected to be the dose that participants will restart treatment with lenalidomide at.

Inclusion Criteria: * Signed Informed Consent * Adult patients 18 years old or older * All study participants must be registered into the mandatory Lenalidomide or Pomalidomide Pregnancy Prevention Plan, and be willing and able to comply with the requirements. * Females of reproductive potential must adhere to the pregnancy testing and contraceptive techniques as required by the Pregnancy Prevention Plan. * Patient diagnosed with multiple myeloma or amyloidosis, with history of HSR to lenalidomide or pomalidomide, who had experienced moderate-severe (Grade ≥2 CTCAE v5.0) cutaneous reactions to IMiDs, with or without being symptomatic (itchy rash). Patients who developed HSR to IMiDs (lenalidomide or pomalidomide) will be assessed according to the CTCAE v 5.0 grading criteria during enrolment, and the severity of the grading (Grade ≥ 2 or otherwise) is recorded for the purpose of future subgroup analysis. OR * Complained of angioedema or anaphylaxis reactions attributable to lenalidomide or pomalidomide. * Patients must be afebrile at least 48 hours prior to proposed desensitization day. * For patients with existing body rash, a complete resolution of rash is needed prior to Rapid Desensitization Program procedures at least 7 days prior to desensitization. * Patients may continue to administer their current medication prior to the start of Rapid Desensitization Program (RDP). Best possible medication history will be taken prior to RDP, with the exception of withholding beta- blockers on the day of desensitization. Patient's allergy history will be documented. Exclusion Criteria: * Female who is pregnant or suspected of being pregnant or breast feeding or likely to breast feed during the study duration * Inability to take oral medications. * History of Steven-Johnson Syndrome (SJS), Toxic Epidermal Necrolysis (TEN) and Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS). * Patients who are taking IMiDs-based therapy for an indication other than multiple myeloma (MM) and/or systemic amyloidosis (AL). * The development of erythema nodosum, if characterized by a desquamating rash while taking thalidomide, IMiDs or similar drugs. * Active viral infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV). Patients who are seropositive because of hepatitis B virus vaccine or previous infection (HepB core Ab +, but HepB sAg negative) are eligible. * Patients who, for whatever reason, are unable to tolerate IMiDs (other than hypersensitivity reactions). * Patients who have completed 3 RDPs and continued to have breakthrough hypersensitivity reactions (HSR) post Rapid Desensitization Program (RDP). * Patients who had experienced IMiDs-related hypersensitivity reaction that is less than Grade 2 (Grade 1) as per CTCAE v5.0.
