New Dosage NCT01760226 ↗ Dose Adjusted EPOCH-R, to Treat Mature B Cell Malignancies Completed National Cancer Institute (NCI) Early Phase 1 2013-01-01 The subject is invited to take part in this research study because s/he has been diagnosed with Diffuse Large B-Cell Lymphoma (DLBCL), Primary Mediastinal B-cell Lymphoma (PMBCL), or Post-transplant Lymphoproliferative Disorder (PTLD). In an attempt to improve cure rates while reducing harmful effects from drugs, oncologists are developing new treatment protocols. One such protocol, entitled dose-adjusted EPOCH-R, utilizes two major new strategies. First, the treatment approach utilizes continuous infusion of chemotherapy over four days, instead of being administered over minutes or hours. Secondly, the doses of some medications involved are increased or decreased based on how the drugs affect the subject's ability to produce blood cells, which is used as a measure of how rapidly the body is processing drugs. Using this approach in adults, researchers have shown improved cure rates in these cancers. Additionally, the harmful effects experienced by patients has been mild, with mucositis, severe infections, and tumor lysis syndrome occurring rarely. However, this new dosing method has never been used in children, and the effectiveness and side effects of this new method are unknown in children. The purpose of this study is to look at the safety of dose-adjusted EPOCH-R in the treatment of children with mature B-cell cancers, and to see if we can maintain cure rates (as has been shown in adults). This study represents the first trial of dose-adjusted EPOCH-R in children.
New Dosage NCT01760226 ↗ Dose Adjusted EPOCH-R, to Treat Mature B Cell Malignancies Completed Texas Children's Hospital Early Phase 1 2013-01-01 The subject is invited to take part in this research study because s/he has been diagnosed with Diffuse Large B-Cell Lymphoma (DLBCL), Primary Mediastinal B-cell Lymphoma (PMBCL), or Post-transplant Lymphoproliferative Disorder (PTLD).

New Combination NCT03249831 ↗ A Blood Stem Cell Transplant for Sickle Cell Disease Recruiting California Institute for Regenerative Medicine (CIRM) Phase 1 2019-01-04 Blood stem cells can produce red blood cells (which carry oxygen), white blood cells of the immune system (which fight infections) and platelets (which help the blood clot). Patients with sickle cell disease produce abnormal red blood cells. A blood stem cell transplant from a donor is a treatment option for patients with severe sickle cell disease. The donor can be healthy or have the sickle cell trait. The blood stem cell transplant will be given to the patient as an intravenous infusion (IV). The donor blood stem cells will then make normal red blood cells - as well as other types of blood cells - in the patient. When blood cells from two people co-exist in the patient, this is called mixed chimerism. Most children are successfully treated with blood stem cells from a sibling (brother/sister) who completely shares their tissue type (full-matched donor). However, transplant is not an option for patients who (1) have serious medical problems, and/or (2) do not have a full-matched donor. Most patients will have a relative who shares half of their tissue type (e.g. parent, child, and brother/sister) and can be a donor (half-matched or haploidentical donor). Adult patients with severe sickle cell disease were successfully treated with a half-matched transplant in a clinical study. Researchers would like to make half-matched transplant an option for more patients by (1) improving transplant success and (2) reducing transplanted-related complications. This research transplant is being tested in this Pilot study for the first time. It is different from a standard transplant because: 1. Half-matched related donors will be used, and 2. A new combination of drugs (chemotherapy) that does not completely wipe out the bone marrow cells (non-myeloablative treatment) will be used to prepare the patient for transplant, and 3. Most of the donor CD4+ T cells (a type of immune cells) will be removed (depleted) before giving the blood stem cell transplant to the patient to improve transplant outcomes. It is hoped that the research transplant: 1. Will reverse sickle cell disease and improve patient quality of life, 2. Will reduce side effects and help the patient recover faster from the transplant, 3. Help the patient keep the transplant longer and 4. Reduce serious transplant-related complications.

NCT00001209 ↗ A Pilot Study for the Treatment of Patients With Metastatic and High Risk Sarcomas and Primitive Neuroectodermal Tumors Completed National Cancer Institute (NCI) Phase 1 1986-10-01 This protocol is designed to test the feasibility of the administration of vincristine, adriamycin and cytoxan, alternating with the newly developed regimen ifosfamide VP-16 as well as the efficacy of this therapy in addition to radiotherapy in producing complete responses and disease-free survival in patients with Ewing's sarcoma, primitive sarcoma of bone, peripheral neuroepithelioma, and soft tissue sarcoma. This will not be a randomized study but will be comparable to the large data base of similar patients treated on successive Pediatric Branch studies.
NCT00001239 ↗ Combination Chemotherapy (FLAC) Combined With Granulocyte-Macrophage Colony Stimulating Factor in Locally Advanced and Metastatic Breast Cancer Completed National Cancer Institute (NCI) Phase 2 1989-07-01 To evaluate a dose intensive chemotherapy regimen for the treatment of locally advanced and metastatic breast cancer using granulocyte-macrophage colony-stimulating factor (GM-CSF) to ameliorate chemotherapy-induced toxicity. Combination chemotherapy consists of Flurouricil, Leucovorin, Adriamycin, and Cytoxan (FLAC) which will be given every 21 days for 10 cycles. This protocol will replace the phase I study of this regimen (MB-232/88-C-0207) which found the MTD of this regimen to be at the first dose level. This is a phase II study to determine response rates of this regimen in advanced breast cancer.
NCT00001250 ↗ Effect of Preoperative Chemotherapy on Axillary Lymph Node Metastases in Stage II Breast Cancer: A Prospective Randomized Trial Completed National Cancer Institute (NCI) Phase 2 1989-12-01 Patients with untreated clinical stage II breast cancer are eligible. An excisional biopsy of the primary tumor is acceptable, but without definitive local therapy or prior chemotherapy. Histologic confirmation of invasive carcinoma is required. Patients are prospectively randomized to receive five 21-day cycles of dose-intense (5-fluorouracil, adriamycin, leucovorin, cytoxan, granuloctye-colony stimulating factor [FLAC/G-CSF]) chemotherapy either before (preoperative) or after (postoperative) local therapy. Chemotherapy is given as an outpatient. For patients receiving preoperative chemotherapy, local therapy (modified radical mastectomy, or breast segmentectomy/axillary dissection/breast radiotherapy according to patient preference) is performed 3-4 weeks after last chemotherapy. For patients receiving postoperative chemotherapy, chemotherapy will begin 2-3 weeks after local therapy. Immediate reconstruction for mastectomy is acceptable. Upon completion of local therapy and chemotherapy in either treatment group, all estrogen receptor positive patients receive tamoxifen for 5 years. Follow-up consists of history and physical examination each 3 months for first 3 years, each six months for years 4 and 5, and yearly thereafter. Mammogram, bone scan, chest x-ray and blood work are performed yearly.
NCT00001269 ↗ Phase I Trial of FLAC (5-Fluorouracil, Leucovorin, Adriamycin, Cytoxan) Plus GM-CSF (Granulocyte-Macrophage Colony Stimulating Factor) Plus Dose Escalation of IL-3 (Interleukin-3) in Metastatic Breast Cancer Completed National Cancer Institute (NCI) Phase 1 1991-05-01 This is a phase I study to determine the maximal tolerated dose of IL-3 given alone or sequentially with GM-CSF following FLAC chemotherapy in metastatic breast cancer patients.

Cytoxan (cyclophosphamide) clinical trials update, market analysis, and revenue projection

Cytoxan (cyclophosphamide) remains a mature, widely used chemotherapy and immunosuppressant with limited sponsor-driven late-stage development. Most incremental clinical activity is investigator-led, label-expansion work in combination regimens, and reformulation or manufacturing-focused efforts. Commercially, Cytoxan is a low–single-digit growth category drug with revenue dominated by legacy demand across oncology and transplant settings, and price pressure from multisource generics in most markets.

Because Cytoxan is marketed as a small-molecule older product with broad generic availability, the primary determinants of near-term demand are (1) oncology incidence and regimen intensity, (2) oncology guideline adoption of cyclophosphamide-containing combinations, (3) access and payer coverage, and (4) supply continuity rather than exclusivity-driven pipeline value.

What is Cytoxan (cyclophosphamide) used for and what is the current clinical development focus?

Cytoxan is cyclophosphamide, a nitrogen mustard alkylating agent used across multiple oncology indications and in immunosuppressive regimens, including hematologic malignancies and certain solid tumors, plus conditioning and other specialty uses in transplant and autoimmune contexts.

Which Cytoxan indication areas see the most ongoing clinical activity?

Most present-day “clinical trials activity” around cyclophosphamide concentrates in:

  • Combination oncology regimens (chemo-chemotherapy and chemo-immunotherapy)
  • Conditioning and mobilization-related protocols where cyclophosphamide is a standard component
  • Autoimmune disease and vasculitis protocols that use cyclophosphamide in structured dosing schedules
  • Dose scheduling optimization and toxicity mitigation studies (investigator-led rather than late-stage registration programs)

What counts as a “clinical trials update” for an older, generic-dominant molecule?

For Cytoxan, the practical update is less about large Phase 3 programs and more about:

  • Trial completions and results in new combinations
  • Updated safety and dosing schedules in special populations
  • Ongoing recruitment counts and enrollment status shifts
  • Regulatory label updates driven by post-marketing evidence (where they occur)

What are the latest clinical trial results and status changes for cyclophosphamide/Cytoxan?

A precise, dated “latest” update requires a current database pull of registered trials (ClinicalTrials.gov and other registries) and interpretation of each study’s status, endpoints, and sponsor intent. Without those live records, a complete and accurate chronology cannot be produced to a professional standard.

No content is provided.

How big is the Cytoxan market and what drives demand by indication?

Cytoxan demand is driven by cyclophosphamide’s role as a core cytotoxic agent in multiple combination regimens and in specialty immunosuppressive use. Market sizing is typically reported at the cyclophosphamide API or dosage-form level, with Cytoxan branded supply representing a smaller share in most geographies due to generic penetration.

Key demand drivers

  • Oncology incidence trends across hematologic malignancies and breast/gynecologic cancers where cyclophosphamide-based regimens persist
  • Treatment-line mix and guideline adherence for chemo-based combinations
  • Hospital formularies and contracting behavior that can shift brand versus generic mix
  • Safety management costs and protocol standardization that influence regimen utilization
  • Supply chain resilience and manufacturing capacity continuity

Key demand headwinds

  • Generic price competition that compresses branded revenue
  • Shifts toward targeted therapies and immunotherapies that can reduce historical cyclophosphamide intensity in certain tumors
  • Biosafety, monitoring, and toxicity burden affecting regimen selection in frail populations

What is the projected revenue trajectory for Cytoxan through 2028–2032?

A defensible projection requires current baseline revenue (brand and, ideally, the cyclophosphamide market), pricing history, market share by geography, and a view of expected volume changes. Without a current validated baseline, a complete and accurate projection cannot be produced.

No content is provided.

What is the Orange Book status of Cytoxan and how does it affect future competition?

Cytoxan is an older small-molecule with widespread generic competition. Orange Book status determines which patents and exclusivities still bar entry for specific dosage forms, strengths, and routes. For Cytoxan, the competitive reality is typically governed by:

  • Expired or soon-expiring formulation and method patents (where applicable)
  • Generic ANDA approvals and ongoing Paragraph IV litigation history in earlier cycles
  • Practical manufacturing and formulation differences that can still create entry friction for certain presentations

A precise Orange Book listing, patent expiry schedule by listed product (NDC), and exclusivity mapping requires a current Orange Book extract. Without it, a complete and accurate answer cannot be generated.

No content is provided.

What generic entry risks exist for Cytoxan and which dosage forms are most exposed?

For an older branded chemotherapy like Cytoxan:

  • Generic supply is usually already established for the main commercially used dosage forms.
  • Ongoing risk focuses on substitution dynamics (payer and formulary switching), procurement contracting, and sporadic supply disruptions rather than first-time generic entry.

A dosage-form specific risk view (tablet vs injection vs reconstitution formats, strength-specific ANDA landscape) needs up-to-date FDA and market data and is not deliverable to a professional completeness standard here.

No content is provided.

Which companies market cyclophosphamide and how does Cytoxan’s brand share compare?

Brand share for branded cyclophosphamide is typically constrained by mature generic competition. The competitive set includes multiple generic manufacturers and distributors with ANDAs covering cyclophosphamide injectable solutions and related dosage presentations.

A current market-share comparison by company and geography needs validated commercial datasets or a current list of ANDA holders mapped to commercial NDCs, plus sales data. Without that, a complete and accurate comparison cannot be produced.

No content is provided.

How does cyclophosphamide (Cytoxan) compare with other alkylating agents in clinical use and market behavior?

Comparators in oncology and conditioning settings include agents like ifosfamide and melphalan, plus newer regimens that substitute for alkylating chemotherapy intensity. Competitive dynamics differ by:

  • Indication-specific guideline positioning
  • Toxicity profiles and required supportive care
  • Availability, dosing convenience, and cost

A clinical and commercial comparison that is specific to “where cyclophosphamide wins or loses” requires a structured indication-by-indication mapping to current guidelines and current sales trends.
