Trial Summary

What is the purpose of this trial?

This research study is evaluating a new drug called IPI-145 in combination with the standard drugs fludarabine, cyclophosphamide, and rituximab (FCR), as a possible treatment for chronic lymphocytic leukemia (CLL).

Will I have to stop taking my current medications?

The trial requires that you stop taking foods or medications that strongly affect CYP3A enzymes (which help process drugs in the body) at least one week before starting the study and throughout its duration.

What data supports the effectiveness of the drug combination IPI-145 + FCR for Chronic Lymphocytic Leukemia?

Research shows that the combination of fludarabine, cyclophosphamide, and rituximab (FCR) is highly effective for treating chronic lymphocytic leukemia, with a 95% overall response rate and 72% complete remission in patients. This suggests that adding IPI-145 to this regimen could potentially enhance its effectiveness.12345

Is the combination of IPI-145, fludarabine, cyclophosphamide, and rituximab safe for humans?

The combination of fludarabine, cyclophosphamide, and rituximab (FCR) has been shown to cause significant blood-related side effects, such as myelosuppression (a decrease in bone marrow activity leading to fewer blood cells), which can lead to infections and other complications. This treatment is generally less well tolerated in older patients, especially those over 70 years old.678910

What makes the IPI-145 + FCR drug unique for treating chronic lymphocytic leukemia?

The IPI-145 + FCR drug is unique because it combines a novel agent, IPI-145, with the established FCR regimen (fludarabine, cyclophosphamide, and rituximab), potentially enhancing the treatment's effectiveness while aiming to reduce the high toxicity levels associated with traditional FCR therapy.1351112

Eligibility Criteria

This trial is for younger patients aged 18-65 with confirmed chronic lymphocytic leukemia (CLL) who need treatment but haven't had any yet. They should be relatively healthy, not pregnant, and free from other cancers unless it's low-risk or treated within the past 5 years. People with poor liver or kidney function, heart issues, certain infections or diseases like HIV are excluded.

Inclusion Criteria

I have been diagnosed with CLL and need treatment.
I have not received any treatment for chronic lymphocytic leukemia.
I can carry out all my self-care but cannot do heavy physical work.

Exclusion Criteria

My cancer has spread to my brain or spinal cord.
I do not have any severe illnesses or social situations that would stop me from following the study's requirements.
I've been cancer-free for 5 years, except for certain low-risk types.

Treatment Details

Interventions

  • Cyclophosphamide
  • Fludarabine
  • IPI-145
  • Rituximab
Trial Overview The study tests a new drug called IPI-145 combined with standard CLL treatments: fludarabine, cyclophosphamide, and rituximab (FCR). It aims to see if adding IPI-145 improves outcomes for those who have never been treated for CLL before.
Participant Groups

Experimental Treatment
Group I: IPI-145Experimental Treatment4 Interventions
Phase I-Dose escalation will occur using a standard 3-3 dose escalation beginning in dose level 1 with dose cohorts and escalation. * Each treatment cycle lasts 28 days (except cycle 1, which is 35 days) during which time IPI-145 will be taken twice daily. The study begins with 1 week of IPI-145 monotherapy. * Fludarabine, cyclophosphamide, rituximab (iFCR) - FCR will subsequently be introduced after 1 week and administered at standard dosing for up to 6 cycles, with dose reductions permitted. IPI-145 will be continued through the course of chemotherapy and for up to 2 years maintenance after completing chemotherapy Phase II - 20 additional patients treated with IPI-145 at the Recommended Phase II Dose (RP2D) + fludarabine, cyclophosphamide, rituximab (FCR) with standard dosing.

Findings from Research

The combination therapy of fludarabine, cyclophosphamide, and rituximab (FCR) achieved a high complete remission (CR) rate of 70% in 224 previously untreated patients with chronic lymphocytic leukemia (CLL), indicating its efficacy as an initial treatment.
Despite the high response rate, the treatment was associated with significant side effects, including grade 3 to 4 neutropenia in 52% of treatment courses and a notable incidence of infections, highlighting the need for careful monitoring during therapy.

In a study involving 561 patients with chronic lymphocytic leukaemia, the standard treatment of fludarabine, cyclophosphamide, and rituximab showed a longer median progression-free survival of 55.2 months compared to 41.7 months for the bendamustine and rituximab combination, indicating that the standard therapy is more effective.
However, the bendamustine and rituximab combination was associated with significantly fewer severe side effects, such as neutropenia and infections, making it a potentially safer alternative for patients, especially those over 65 years.
