All Clinical Trials for Zenatane

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00026312 ↗	Isotretinoin With or Without Dinutuximab, Aldesleukin, and Sargramostim Following Stem Cell Transplant in Treating Patients With Neuroblastoma	Active, not recruiting	National Cancer Institute (NCI)	Phase 3	2001-10-18	This partially randomized phase III trial studies isotretinoin with dinutuximab, aldesleukin, and sargramostim to see how well it works compared to isotretinoin alone following stem cell transplant in treating patients with neuroblastoma. Drugs used in chemotherapy, such as isotretinoin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as dinutuximab, may block tumor growth in different ways by targeting certain cells. Aldesleukin and sargramostim may stimulate a person's white blood cells to kill cancer cells. It is not yet known if chemotherapy is more effective with or without dinutuximab, aldesleukin, and sargramostim following stem cell transplant in treating neuroblastoma.
NCT00392327 ↗	Chemotherapy and Radiation Therapy in Treating Young Patients With Newly Diagnosed, Previously Untreated, High-Risk Medulloblastoma/PNET	Active, not recruiting	National Cancer Institute (NCI)	Phase 3	2007-03-26	This randomized phase III trial studies different chemotherapy and radiation therapy regimens to compare how well they work in treating young patients with newly diagnosed, previously untreated, high-risk medulloblastoma. Drugs used in chemotherapy, such as vincristine sulfate, cisplatin, cyclophosphamide, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Carboplatin may make tumor cells more sensitive to radiation therapy. It is not yet known which chemotherapy and radiation therapy regimen is more effective in treating brain tumors.
NCT00392327 ↗	Chemotherapy and Radiation Therapy in Treating Young Patients With Newly Diagnosed, Previously Untreated, High-Risk Medulloblastoma/PNET	Active, not recruiting	Children's Oncology Group	Phase 3	2007-03-26	This randomized phase III trial studies different chemotherapy and radiation therapy regimens to compare how well they work in treating young patients with newly diagnosed, previously untreated, high-risk medulloblastoma. Drugs used in chemotherapy, such as vincristine sulfate, cisplatin, cyclophosphamide, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Carboplatin may make tumor cells more sensitive to radiation therapy. It is not yet known which chemotherapy and radiation therapy regimen is more effective in treating brain tumors.
NCT00867178 ↗	Vorinostat Combined With Isotretinoin and Chemotherapy in Treating Younger Patients With Embryonal Tumors of the Central Nervous System	Active, not recruiting	National Cancer Institute (NCI)	Phase 1	2009-02-25	This pilot clinical trial studies the side effects and the best way to give vorinostat with isotretinoin and combination chemotherapy and to see how well they work in treating younger patients with embryonal tumors of the central nervous system. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as isotretinoin, vincristine sulfate, cisplatin, cyclophosphamide, and etoposide phosphate, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving vorinostat with isotretinoin and combination chemotherapy may be an effective treatment for embryonal tumors of the central nervous system. A peripheral blood stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. This may allow more chemotherapy to be given so that more tumor cells are killed.
NCT01041638 ↗	Monoclonal Antibody Ch14.18, Sargramostim, Aldesleukin, and Isotretinoin After Autologous Stem Cell Transplant in Treating Patients With Neuroblastoma	Completed	National Cancer Institute (NCI)	Phase 3	2009-12-21	This phase III trial is studying the side effects of giving monoclonal antibody Ch14.18 together with sargramostim, aldesleukin, and isotretinoin after autologous stem cell transplant in treating patients with neuroblastoma. Monoclonal antibodies, such as Ch14.18, may find tumor cells and help kill them. Colony-stimulating factors, such as sargramostim, may increase the number of immune cells found in bone marrow or peripheral blood. Aldesleukin may stimulate the white blood cells to kill tumor cells. Isotretinoin may help neuroblastoma cells become more like normal cells, and to grow and spread more slowly. Giving monoclonal antibody Ch14.18 with sargramostim, aldesleukin, and isotretinoin after autologous stem cell transplant may be an effective treatment for neuroblastoma.

Clinical Trials Update, Market Analysis, and Projection for Zenatane

Last updated: October 28, 2025

Introduction

Zenatane (isotretinoin) has established itself as a formidable agent in the treatment of severe recalcitrant nodular acne, positioning itself as a critical player in dermatological therapeutics. As a derivative of vitamin A (retinoid), Zenatane exerts potent anti-inflammatory, anti-seborrheic, and keratolytic effects. With ongoing clinical trials and evolving market dynamics, understanding Zenatane’s current developmental landscape and future commercial trajectory is crucial for stakeholders.

Clinical Trials Landscape

Current Clinical Trials and Recent Findings

Zenatane’s efficacy and safety continue to be examined through multiple phases of clinical research. Recent trials focus primarily on optimizing dosing regimens, reducing adverse effects, and expanding indications.

• Efficacy in Severe Acne: Multiple Phase III trials have reaffirmed Zenatane's superior efficacy in reducing nodular and cystic acne lesions with remission rates exceeding 75% after a 20-week course, consistent with earlier findings [1].

• Safety Profile and Teratogenicity: Robust data uphold the drug’s teratogenic risks, necessitating strict contraceptive measures. Recent trials explore adjunctive measures to mitigate pregnancy-related risks, including enhanced patient education and regulatory compliance.

• Alternative Indications: Emerging studies assess Zenatane's potential for off-label uses, such as severe hidradenitis suppurativa and certain keratinization disorders. Preliminary findings suggest promising anti-inflammatory properties extend beyond acne vulgaris.

Regulatory Updates

• FDA and EMA Status: Zenatane remains an FDA-approved drug with existing REMS (Risk Evaluation and Mitigation Strategies). Discussions are ongoing regarding expanded indications, especially for cases unresponsive to standard therapies.

• Ongoing Trials: ClinicalTrials.gov reports over 15 active studies involving Zenatane. Notably, trials assessing pharmacogenomics aim to personalize dosing, reduce adverse events, and improve compliance.

Challenges in Clinical Development

Despite its proven efficacy, Zenatane’s development faces hurdles such as:

• Managing teratogenicity risks.
• Addressing adverse effects, including mucocutaneous dryness and lipid profile alterations.
• Expanding indications without compromising safety.
