Clinical Trials for Sarcoma

MISTOSUS: Iscador® P (Mistletoe) Immunotherapy To Improve Event Free Survival In Patients With Relapsed Osteosarcoma After Resection Of Pulmonary Metastases

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

HealthScout AI summary: Single-arm study for patients aged 8 to <30 with relapsed osteosarcoma who have had complete resection of all pulmonary metastases within 8 weeks, good organ function, and no active extra-pulmonary disease. Participants receive subcutaneous Iscador P (Viscum album mistletoe extract) three times weekly with individualized dose escalation for up to 52 weeks; the extract is an immunomodulatory biologic with lectins/viscotoxins aiming to enhance anti-tumor immunity and potential cytotoxicity.

ClinicalTrials.gov ID: NCT05726383

Phase II Study of Enasidenib in IDH2-mutated Malignant Sinonasal and Skull Base Tumors

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Enasidenib is a selective mutant IDH2 inhibitor that lowers 2-HG to promote differentiation; key exclusions include prior IDH inhibitor use and significant uncontrolled comorbidities.

ClinicalTrials.gov ID: NCT06176989

B7-H3-Specific Chimeric Antigen Receptor Autologous T-Cell Therapy for Pediatric Patients With Solid Tumors (3CAR)

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

HealthScout AI summary: Pediatric and young adult patients (≤21 years) with measurable, relapsed/refractory B7‑H3 (CD276)–positive solid tumors, including CNS involvement, receive lymphodepleting fludarabine/cyclophosphamide followed by a single IV infusion of autologous B7‑H3–targeted CAR T cells. The investigational therapy uses second‑generation CAR T cells engineered to recognize B7‑H3 to mediate antigen-directed cytotoxicity, with dose escalation to define safety and preliminary activity.

ClinicalTrials.gov ID: NCT04897321

A Phase II Study of All-Trans Retinoic Acid (ATRA) and Cemiplimab in Patients With Advanced Leiomyosarcoma

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

HealthScout AI summary: Adults with metastatic or unresectable leiomyosarcoma after prior systemic therapy (including allowable prior PD-1/PD-L1 exposure without severe irAEs) receive cemiplimab (anti–PD-1) every 3 weeks with short-course oral all-trans retinoic acid (ATRA) for the first three cycles, then cemiplimab alone until progression. ATRA, a retinoic acid receptor agonist that can reduce myeloid-derived suppressor cells, is paired with PD-1 blockade to potentially enhance antitumor immunity.

ClinicalTrials.gov ID: NCT06528769

A Multicenter Phase 1/2a, Open-Label Study of SQ3370 in Patients With Advanced Solid Tumors

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

HealthScout AI summary: Adults with advanced solid tumors eligible for anthracyclines and with at least one injectable lesion, including expansion cohorts for unresectable/metastatic soft tissue sarcoma (anthracycline‑naïve) and relapsed/metastatic HNSCC after ≤2 prior regimens. Treatment is SQ3370, a locally activated doxorubicin platform using intratumoral SQL70 biopolymer and IV SQP33 protodrug that releases native doxorubicin at the injected tumor via bioorthogonal click chemistry to enhance local exposure and limit systemic toxicity.

ClinicalTrials.gov ID: NCT04106492

A Phase I/II Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Clinical Activity of HH2853 in Patients with Relapsed/Refractory Non-Hodgkin's Lymphomas or Advanced Solid Tumors

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

HealthScout AI summary: Adults with relapsed/refractory follicular lymphoma (≥2 prior lines), DLBCL not transplant candidates, PTCL (≥1 prior line), unresectable/metastatic epithelioid sarcoma, or advanced solid tumors enriched for PRC2 dependence (e.g., EZH2 mutation, INI1/SMARCA4 loss, ARID1A or BAP1 mutations) receive oral HH2853 (epsametostat), a dual EZH1/EZH2 inhibitor, given BID in 28‑day cycles.

ClinicalTrials.gov ID: NCT04390737

A Randomized Phase III Trial of Doxorubicin + Pembrolizumab Versus Doxorubicin Alone for the Treatment of Dedifferentiated Liposarcoma (DDLPS), Undifferentiated Pleomorphic Sarcoma (UPS) and Related Poorly Differentiated Sarcomas

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

HealthScout AI summary: Adults with metastatic or unresectable dedifferentiated liposarcoma, undifferentiated pleomorphic sarcoma, or related poorly differentiated sarcomas (ECOG 0–1, anthracycline‑naïve) are randomized to first-line doxorubicin plus pembrolizumab versus doxorubicin alone, with crossover to pembrolizumab at progression in the control arm. Pembrolizumab is an anti–PD-1 antibody designed to restore T‑cell antitumor activity; the study tests whether upfront addition improves PFS (with separate analyses for UPS-family tumors and DDLPS) and impacts OS versus reserving pembrolizumab for later.

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

Started >3 years ago
