Patient case: 57-year-old male with lung adenocarcinoma; genetic feature: KRAS (G12V), high tumor mutational burden

Clinical trial: Myeloma-Developing Regimens Using Genomics (MyDRUG)

Summary: The MyDRUG study is a type of Precision Medicine trial to treat patients with drugs targeted to affect specific genes that are mutated as part of the disease. Mutations in genes can lead to uncontrolled cell growth and cancer. Patients with a greater than 30% mutation to any of the following genes; CDKN2C, FGFR3, KRAS, NRAS, BRAF V600E, IDH2 or T(11;14) can be enrolled to one of the treatment arms. These arms have treatments specifically directed to the mutated genes. Patients that do not have a greater than 30% mutation to the genes listed can be enrolled to a non-actionable treatment arm.
  The genetic sequencing of the patient's tumor is required via enrollment to the MMRF002 study: Clinical-grade Molecular Profiling of Patients with Multiple Myeloma and Related Plasma Cell Malignancies. (NCT02884102).

Detailed description: The study will enroll 228 patients enrolled to one of six treatment arms. The study is open to patients relapsing with relapsed refractory multiple myeloma, who have
  -  received at least one prior but no more than 3 prior therapies
  -  exposed to both a PI and an IMiD
  -  had early relapse after initial treatment. Relapse is defined as the IMWG uniform response criteria (Kumar et al, 2016). Early relapse as defined by at least one of the following:
  1. Relapse within 3 years post autologous stem cell transplantation (ASCT) on maintenance, or 18 months if unmaintained
  2. Relapse within 18 months of initial non-ASCT based therapy

Eligibility: Inclusion Criteria:
  -  Willing to be registered into the pomalidomide (POMALYST®) Risk Evaluation and Mitigation Strategy (REMS®) program
  -  Enrolled in the MMRF002 Molecular Profiling Protocol (NCT02884102) with report less than 120 days old
  -  Disease free of prior malignancies for ≥ 3 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, carcinoma "in situ" of the cervix or breast, or prostate cancer not requiring therapy
  -  High risk patients with relapsed refractory multiple myeloma (RRMM), who have:
  -  received at least one prior but no more than 3 prior therapies
  -  exposed to both a PI and an IMiD
  -  had early relapse after initial treatmentEarly relapse as defined by at least one of the following: (Relapse is defined as the IMWG uniform response)
  1. Within 3 years post autologous stem cell transplantation (ASCT) on maintenance, or 18 months if unmaintained
  2. Within 18 months of initial non-ASCT based therapy
