A Phase 1 interventional study of Carfilzomib and Cyclophosphamide in Multiple Myeloma, sponsored by Hackensack Meridian Health. Recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-21.
Sponsored by Hackensack Meridian Health · Phase 1, Interventional, and Treatment
This phase I study utilizes a 3+3 design with escalating cohorts of Carfilzomib at 20mg/m2, 27mg/m2, 36mg/m2, 45mg/m2, 56mg/m2, and 70mg/m2 to be administered concomitantly with Cyclophosphamide 2 gm/m2, Dexamethasone and Granulocyte colony-stimulating factor (G-CSF)
This study will be conducted as an open-label Phase I, single-center study in which subjects will receive carfilzomib, in combination cyclophosphamide and dexamethasone, for mobilization of peripheral blood stem cells. Study treatment will be administered in sequential cohorts, with three to six subjects in each cohort.
Following induction therapy, eligible patients will complete screening procedures. Treatment will consist of Dexamethasone 40mg IV/PO to be administered as a premedication. Carfilzomib dosed at each respective cohort level to be administered over 30 minutes followed by Cyclophosphamide dosed at 2gm/m2 administered over 1 hour.
For patients who are naïve to carfilzomib based therapy a priming dose of Carfilzomib (20mg/m2) will be administered 1 week prior to the cohort dosing.
On day 7 subjects will initiate high dose G-CSF injections at 14mcg/kg daily (with a cap of 1440mcg daily). On day 12 peripheral blood stem cell collection will begin per institutional protocol.
After successful peripheral blood stem cell mobilization, patients will proceed to a melphalan based autologous stem cell transplant.
Patients will have disease parameters assessed monthly after the transplant.

INCLUSION CRITERIA Subject has voluntarily agreed to participate by giving written before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care. Informed Consent must be obtained prior to mobilization.
Subject has a of >12 weeks.
EXCLUSION CRITERIA
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Started Oct 2019 (actual). Primary completion is estimated for Aug 2027, 94 months after the start.
Of 201 non-industry phase 1 interventional studies under Multiple Myeloma, half reached primary completion within 57 months of starting (the median), counting those still running; a quarter within 39 and three quarters within 99. This study's planned 94 months is above that.
Counting every sponsor, half of 413 studies reached it within 50 months; a quarter within 33 and three quarters within 75.
How these figures are worked out, and which studies are left out of them.
