Brief Summary:

Study Phase III Randomized Study to Investigate the Use of Acalabrutinib in the Treatment of Patients with Early Stage CLL With High Risk of Early Disease Progression.

The study will consist of a screening phase, a treat¬ment/observation phase until progression, and a follow-up phase for progression in patients who discontinue treatment with Acalabrutinib without confirmed progression. Patients who progress will be followed for survival and initiation of subsequent antileukemic therapy. In the study, 130 patients from 20 centers in Spain with intermediate, high or very high risk will be randomized (1:1) to receive Acalabrutinib (n=65) or clinical observation (n=65). Acalabrutinib will be administered orally 100 mg twice daily on a continuous schedule.

Even though the majority of patients with CLL are currently diagnosed at early stages of the disease, there is a consensus that the standard of care in these patients is clinical observation (watch & wait) despite of the presence of risk factors for premature disease progression. Early treatment in patients with adverse prognostic parameters could prevent a disease evolving to a more advanced stage, and therefore more difficult to treat. So far, conventional chemotherapy did not show any benefit in terms of overall survival in patients with early stage CLL. (Dighiero 1998, Hoechstetter Leukemia 2017) Alongside this, treatment with chemotherapy may provoke two undesired effects: first, the occurrence of bone marrow toxicity that may hamper the subsequent administration of other treatments during the course of the disease; second, but not less relevant, genotoxic drug delivery may elicit a phenomenon of clonal selection leading to the appearance of CLL cells with genetic aberrations associated with refractoriness and aggressive outcome (i.e., TP53).

Against this background, it is of interest to investigate the role of new non-genotoxic drugs in the treatment of patients with CLL in early stages. Among different scores for selecting cases that are likely to progress rapidly, the German CLL Study Group (GCLLSG) risk score that includes 8 independent predictors for OS and PFS, differentiates patients with low-risk PFS vs. those with risk of early disease progression (median PFS 87 months vs. less than 27 months), allowing for a risk-adapted treatment approach in early stage CLL. (Pflug 2014, Langerbeins 2015).

Acalabrutinib, a second-generation, selective inhibitor of BTK, has shown substantial activity in patients with CLL. Acalabrutinib is a non-genotoxic drug active in cases with genetic lesions associated with chemorefratoriness and adverse outcome, including patients with alterations of TP53. Therefore, acalabrutinib represents a suitable compound for the treatment of patients with CLL in early stages with risk of early disease progression, including the high-risk CLL patient population with TP53 alterations.

Primary Outcome Measures :
  1. Event-Free Survival (EFS) [ Time Frame: From randomization to 60 months ]
    EFS is defined as the time between the date of randomization and time point of symptomatic disease progression with treatment indication according to the iwCLL-Guidelines, initiation of subsequent treatment for CLL or death by any cause, whichever occurs first.


Secondary Outcome Measures :
  1. Progression-Free Survival (PFS) [ Time Frame: From randomization to 60 months ]
    Time between the date of randomization and progression of disease or death from any cause, whichever occurs first.

  2. Overall Survival (OS) [ Time Frame: From randomization to 60 months ]
    Time between the date of randomization and death from may cause.

  3. Time To Next Treatment (TTNT) [ Time Frame: From randomization to 60 months ]
    Time from randomization until the date of initiation of subsequent treatment for CLL or death from any cause.

  4. Objetive Response Rate (ORR) [ Time Frame: From randomization to 60 months ]
    Is defined as the proportion of patients who achieve a CR (Complete Remission), CRi (CR with incomplete bone marrow recovery), nPR (nodular Partial Remission) or PR (Partial Response) over the course of the study. Patients who achieve a PR with lymphocytosis will be included in the ORR. The rate of MRD-negative disease (MRD: Minimal Residual Disease) will also be calculated. The IWCLL guidelines (Hallek, 2018) will be used to measure response in CLL.

    • Evidence of progressive marrow failure as manifested by the development of, or worsening of, anemia and/or thrombocytopenia.
    • Massive (i.e. ≥6 cm below the left costal margin) or progressive or symptomatic splenomegaly.
    • Massive nodes (i.e. ≥10 cm in longest diameter) or progressive or symptomatic lymphadenopathy.
    • Progressive lymphocytosis with an increase of ≥50% over a 2-month period, or lymphocyte doubling time (LDT) of less than 6 months.
    • A minimum of any one of the following disease-related symptoms: unintentional weight loss ≥10% within the previous 6 months, significant fatigue (i.e., ECOG PS 2 or worse; cannot work or unable to perform usual activities), fevers of ≥38.0°C for 2 or more weeks without other evidence of infection, or night sweats for more than 1 month without evidence of infection.
    • Autoimmune complications including anemia or thrombocytopenia poorly responsive to corticosteroids.
    • Symptomatic or functional extranodal involvement (e.g., skin, kidney, lung, spine).
  7. GCLLSG prognostic index with intermediate (3-5), high (6-10) or very high (11-14) risk scores.
  8. Must have an Eastern Cooperative Oncology Group (ECOG) performance status score of ≤1.
  9. All sexually active subjects with the capacity to reproduce (male and female) must use high-efficacy contraceptive methods during the course of the study. These restrictions apply for 3 months after the last dose of acalabrutinib. High-efficacy contraceptive methods include:

    • Total abstinence when consistent with the subject's typical and preferred lifestyle (periodic abstinence [e.g. calendar methods, ovulation, symptothermal and post-ovulation methods] and the withdrawal method are not acceptable contraceptive methods).
    • Female sterilisation defined as surgical hysterectomy, bilateral oophorectomy, or tubal ligation at least six weeks prior to the study treatment (a simple oophorectomy does not meet the definition of female sterilisation).
    • Male sterilisation (at least six months before screening). A man who has undergone a vasectomy must be the only partner who is a study subject.
    • Combination of two of the following methods (a+b or a+c or b+c):

      1. Use of oral, injected or implanted hormonal contraceptives, or other hormonal contraceptive methods that have a comparable efficacy (failure rate < 1%), for example, hormonal vaginal ring or transdermal hormonal contraceptive. If an oral contraceptive is used, women must use the same pill for a minimum of three months before taking the study treatment.
      2. Placement of an intrauterine device (IUD) or an intrauterine system (IUS).
      3. Barrier contraceptive methods: condom or cervical cap (cervical/vault diaphragm or cap) with foam/gel/film/spermicidal cream/vaginal suppository.
  10. Female subjects of childbearing potential must have a negative serum pregnancy test at screening. Females of child bearing potential are defined as sexually mature women without prior hysterectomy or who have had any evidence of menses in the past 12 months. However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to other causes, including prior chemotherapy, anti-estrogens, or ovarian suppression.
