The test must have a sensitivity of at least 50 mIU/mL. Study participants who are FCBP must either commit to continued abstinence from heterosexual intercourse or begin two acceptable methods of birth control, one highly effective method and one additional effective method at the same time, at least 28 days before she starts taking POM through 30 days after the last dose of POM and 60 days after the last dose of Vactosertib. FCBP must also agree to ongoing pregnancy testing during the entire duration of treatment. Men must agree to use a latex or synthetic condom during sexual contact with a FCBP even if they have had a vasectomy from the time of signing the informed consent form through 60 days after the last dose of POM or Vactosertib. These same patients must not donate sperm. All patients must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure. All patients enrolled into this trial, must agree to be registered in and must comply with all requirements of the Pomalidomide Risk Evaluation and Mitigation Strategy (POM REMS™) program.~Exclusion Criteria:~* Prior therapy with Vactosertib or received any investigational drug within the prior 28 days.~* Plasma Cell Leukemia~* Patients with solitary plasmacytoma~* Patients who are primarily eligible for autologous stem cell transplant~* Prior anti-cancer therapy (chemotherapy, targeted agents, radiotherapy, and immunotherapy) within the prior 21 days except for alkylating agents (e.g., melphalan) within the prior 28 days.~* Prior treatment with pomalidomide.~* Subjects with active malignancy and/or cancer history that may confound the assessment of the study endpoints. Patients with a past cancer history (within 2 years of entry) with substantial potential for recurrence and/or ongoing active malignancy must be discussed with the trial collaborator, MedPacto Inc., before study entry. Patients with the following neoplastic diagnoses are eligible: non-melanoma skin cancer, carcinoma in situ (including superficial bladder cancer), cervical intraepithelial neoplasia, and organ-confined prostate cancer with no evidence of progressive disease~* Any \> grade 1 (according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTC AE) v.4.03) adverse reaction unresolved from previous treatments or not readily managed and controlled with supportive care. The presence of alopecia of any grade and peripheral neuropathy ≤ Grade 2 without pain is allowed.~* Previous allogeneic stem cell transplantation with active graft versus host disease (GVHD), or treatment with immunosuppressive therapy in the 2 months prior to study entry.~* No oral corticosteroids 3 days before initiating combinations Vactosertib/POM; inhaled corticosteroids are permitted.~* Patient is known to be human immunodeficiency virus (HIV) positive, or have chronic or active Hepatitis B (core- or surface antigen-positive) or active hepatitis C infection.~* Clinically significant cardiovascular disease (e.g., uncontrolled or any New York Heart Association (NYHA) Class 3 or 4, congestive heart failure, uncontrolled or unstable angina, history of myocardial infarction or stroke within 6 months prior to study entry, or clinically significant arrhythmias not controlled by medication).~* Major abnormalities identified by ECG or echocardiogram (ECHO), at the Investigator's discretion.~* Presence of aneurisms of the ascending aorta or aortic stress.~* Hypertension that is not controlled by standard medication (to 150/90 mmHg or below).~* Uncontrolled, clinically significant pulmonary disease (e.g., chronic obstructive pulmonary disease (COPD), pulmonary hypertension) that in the opinion of the investigator would put the patient at significant risk for pulmonary complications during the study.~* Uncontrolled intercurrent illness including, but not limited to, uncontrolled infection, disseminated intravascular coagulation (DIC), or psychiatric illness/social situations that would limit compliance with study requirements.~* History of erythema multiforme or severe hypersensitivity to prior IMiD's such as thalidomide and lenalidomide.~* Patients requiring hemodialysis~* The patient is receiving medications that are:~  * Exclusively or primarily eliminated by cytochrome P-450 isozyme 3A4 (CYP3A4).~ * Exclusively or primarily eliminated by Uridine 5'-diphospho (UDP)-glucuronyltransferase 1A1 (UGT1A1).~ * Substrates for the drug transporter multidrug resistance protein 1 (MDR1) have a narrow therapeutic window; or which are strong inhibitors of drug transporter MDR1.~* Patients should have discontinued strong CYP1A2 inhibitors (e.g. ciprofloxacin and fluvoxamine) at least five half-lives before beginning study treatment.~* Inability to tolerate thromboprophylaxis (Required Concurrent Medications)

Study Arms:
- Vactosertib + Pomalidomide (Type: EXPERIMENTAL): Vactosertib tablets, taken once daily for the first and second dose levels and twice a day for third and fourth dose level levels for 5 days followed by 2 days without treatment, repeated for 28-day cycles until evidence of progressive disease, intolerable toxicity, or participant discontinuation.~For dose escalation - dosing initiated at 60 mg once daily by oral administration and will be increased to determine MTD. Provisional subsequent doses are 60, 120, once daily and 100 mg and 200 mg twice daily on days 1-5, 8-12, 15-19 and 22-26. Extension cohorts will enter at 200 mg twice daily (i.e. if MTD not defined) for 12 months until progression or intolerable toxicity.~POM is administered orally (4 mg/day daily on Days 1 - 21 days). Treatment will occur in a suitable outpatient ambulatory care setting that is equipped for monitoring of patients with hematopoietic malignancies undergoing early clinical trial research.

Based on this trial design, predict the completion outcome and termination type (if applicable).
