Active clinical trials for "Precursor Cell Lymphoblastic Leukemia-Lymphoma"

The biological characteristics of the adult LAL, karyotypic and phenotypic particular, are fundamentally different from those of Acute Lymphoblastic Leukemia (ALL) children and, consequently, the results of treatment are substantially lower. Additionally, elderly patients tolerate the drugs considered relatively low-key in the management of the LAL and suffer more toxicity. Although the LAL is much more common in patients over 60 years of age than in younger adults, older adults with ALL are clearly underrepresented in prospective controlled studies. A good portion of elderly patients are not able to tolerate the intensity of the standard treatment applied to children or young adults and a significant portion of them receive only palliative or supportive treatment. The data in the literature relating specifically to the elderly population are scarce and most of them have obtained a stratification by age of study designed for young people (CALGB, GMALL, PETHEMA). To date, the group's recommendation was to treat PETHEMA the LAL-96RI protocol for elderly patients because this protocol less aggressive than those used in high-risk ALL. However, the development of inhibitors of tyrosine kinases LAL effective in Bcr / abl positive, a relatively common type of LAL in the older patient, requires a differentiated treat these patients. Moreover, analysis of data from patients treated so far with the LAL-96RI protocol has shown mediocre results even for LAL Bcr / abl negative. This analysis also showed a significant benefit in survival related to the reduction of treatment (removal of the L-asparaginase during induction and cyclophosphamide at the end of induction) attributed to a reduction in toxicity

A Phase 1, Multicenter, Open-label, Dose-escalation Study to Evaluate Safety, Tolerability, Pharmacokinetics, and Clinical Activity of Orally Administered LP-108 as Monotherapy and in Combination with Azacitidine in Subjects with Relapsed or Refractory Myelodysplastic Syndromes (MDS), Chronic Myelomonocytic Leukemia (CMML), or Acute Myeloid Leukemia (AML)

This study is about an anticancer drug called ponatinib which is a tyrosine kinase inhibitor given with chemotherapy to children, teenagers, and young adults up to 21 years of age with Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia who have relapsed or are resistant to other treatment. The main aims of this study are to confirm the highest dose of ponatinib tablets and minitablet capsules that can be given to participants with acceptable side effects, and to evaluate if participant's leukemia achieves remission. Participants will take ponatinib tablets with chemotherapy. For participants who cannot swallow tablets or who are receiving less than a 10 mg dose, a capsule with small ponatinib minitablets inside will be provided. Participants will take ponatinib for 10 weeks in combination with chemotherapy (reinduction and consolidation blocks) and will be followed up for at least 3 years.

The study aims to evaluate the safety, efficacy, and tolerability of subcutaneous (SC) blinatumomab for treatment of Acute Lymphoblastic Leukemia (ALL), to determine the maximum tolerated dose (MTD), and recommended phase 2 dose(s) (RP2D) of SC administered blinatumomab. It will also conduct a clinical PK evaluation of SC1 and SC2 blinatumomab formulations.

A Study of CAR-T Cells Therapy for Patients With Relapsed and/or Refractory Central Nervous System Hematological Malignancies

A Study of Humanized CD19 CAR-T Cells Therapy for Patients With Relapsed and/or Refractory B-cell Acute Lymphoblastic Leukemia and B-cell Non-Hodgkin's Lymphoma.

This research study is evaluating the safety and efficacy of administering venetoclax and inotuzumab ozogamicin in combination in patients with acute lymphoblastic leukemia (ALL) The names of the study drugs involved in this study are: Venetoclax Inotuzumab ozogamicin Dexamethasone

Philadelphia chromosome (BCR-ABL1, Ph) is the most common genetic abnormality in acute lymphoblastic leukemia (ALL) and an independent prognostic risk factor. With the increase of age, the incidence of patients over 60 years old can reach 50%, whose 5-year overall survival rate was less than 20%. With the application of tyrosine kinase inhibitor (TKI), the prognosis of Ph positive ALL patients is greatly improved. At present, TKI combined with chemotherapy has become the first-line treatment recommended in the guideline of Ph positive ALL patients. However, with the use of imatinib, more and more patients develop drug resistant to imatinib. In addition, the clinical data showed that the MRD negative rate in patients treated with imatinib combined with hyper CVAD was only 22% three months later, which was far lower than 31% of the second generation TKI and 52% of the third generation TKI. Second generation TKI dasatinib and nilotinib can overcome most imatinib resistant kinase region mutations. However, patients with severe hemocytopenia, infection or other complications are often unable to tolerate the standard chemotherapy. In addition, due to the high cost, some patients can't afford the long-term use. Flumatinib is the first approved second generation TKI in China and a derivative of imatinib. Compared with imatinib, it introduced trifluoromethyl, substituted pyridine ring for benzene ring, and kept the direction of amide bond, which made the inhibitory effect of flumatinib on common kinase mutations significantly better than that of imatinib. In addition, compared with the second-generation TKI recommended in the first line of current guidelines, the incidence of quality of life related adverse reactions of flumatinib is lower, and no specific adverse reactions of the second-generation TKI have been reported. We plan to enroll 28 patients with Ph positive ALL. All patients are diagnosed by morphology, immunology, cytogenetics and molecular biology (MICM). According to subjects' age, we will divide them into two groups. Subjects aged 60 years or older are received flumatinib and dose-adjusted VDCP or prednisone regimen. Subjects younger than 60 years are received flumatinib and hyper-CVAD regimen. MRD are examined on the 8th, 15th and 29th day after chemotherapy. Then, MRD will be monitored in the third, 6th, 9th, 12th, 15th, 18th, 21th and 24th months after chemotherapy to evaluate the effect.

This is a single arm, open-label, single-center, phase I/II study to determine the safety and efficacy of CD19 CAR-T( ssCART-19) combined with feeding T cells (FTCs) as consolidation therapy in patients diagnosed with de novo Philadelphia chromosome positive CD19+ B-ALL. The study will contain the following sequential phases: screening, lymphocyte apheresis, induction and consolidation chemotherapies combined with tyrosine kinase inhibitors. Once in complete response, patients will receive four cycles of ssCART-19s, namely one cycle of ssCART-19 infusion followed by another three cycles of ssCART-19 and FTC infusion. The role of FTCs is to mimic leukemia cells. Therefore, they are expected to stimulate in vivo expansion and persistence of ssCART-19. Considering the limited number of lymphocytes obtained by a single apheresis from patients and cost-efficacy, in addition to safety, we will explore the range of biologically active doses of FTCs in a phase I study. Based on preclinical data, FTCs stimulation of ssCART-19 at a ratio of 1:1 could achieve the best activation response, so 5×106/kg dosage of FTCs was set as the initial dosage in the study, and lower dose was also evaluated. In this study, FTCs will be administered at the dose of 5×106/kg, 3.25×106/kg or 2×106/kg two hours after ssCART-19 infusion on day 1 and once again administered at the same dose on day 8. After ssCART-19 and FTCs infusion, efficacy will be assessed by detecting molecular response for 6 months, PFS and OS will be followed up for 2 years. In phase II, we will expand the study at optimal biological doses of FTCs, and further evaluate the efficacy and safety of the innovative combination therapy of CD19 CAR-T and FTCs.

This Phase 1 Study is an open-label, non-randomized, dose escalation, safety, efficacy, pharmacokinetic, and pharmacodynamic evaluation study of INA03 administered as a single agent IV infusion every 2 weeks to patients ≥18 years of age with R/R AML, MLL, or ALL. The study will be performed in 2 parts: a Dose Titration for Day 1 study (Part 1) followed by a Dose Escalation Part (Part 2) of INA03 used as monotherapy.
