Clinical Use: Lenzilumab has completed Phase II clinical trial for uncontrolled asthma, whereas a Phase II study in patients with inadequately controlled rheumatoid arthritis has been terminated. A Phase I trial in patients with previously treated chronic myelomonocytic leukemia (CMML) is ongoing [4].
Immuno Disease Comments: Phase 1 clinical candidate for CLL (see NCT02546284).
acalabrutinib  [ FDA (2017) (Drugs.com) ]
Clinical Use: Having already received FDA Orphan Drug Designation and Breakthrough Therapy Designation for mantle cell lymphoma (MCL: a rare and fast-growing type of non-Hodgkin lymphoma), in August 2017 the FDA granted priority review for acalabrutinib's New Drug Application (NDA), based on results from a Phase 2 study in relapsed/refractory MCL (NCT02213926). This resulted in full FDA approval in October 2017 (link to FDA announcement). This approval is for the treatment of MCL patients who have received at least one prior therapy.

Additional trials are evaluating acalabrutinib in other cancers. For example: Phase 3 trial in patients with chronic lymphocytic leukemia (CLL)- see NCT02475681 and NCT02477696; Phase 2 clinical trials to assess acalabrutinib's efficacy against other B cell malignancies and a variety of solid tumours (such as bladder, prostate and non-small cell lung cancers). In total, more than 25 acalabrutinib clinical trials are underway or have completed. For a list of all registered trials, link here to ClinicalTrials.gov. Phase 1/2 trial results in patients with CLL are reported by Byrd et al. (2015) [1].

In the European Union, the EMA has granted acalabrutinib orphan designation for three rare diseases (as of 2016): chronic lymphocytic leukaemia / small lymphocytic lymphoma, lymphoplasmacytic lymphoma and mantle cell lymphoma.
Immuno Disease Comments: Phase 3 clinical candidate for CLL.
Clinical Use: Spebrutinib has been granted orphan drug designation by the EMA (using the chemical name n-(3-(5-fluoro-2-(4-(2-methoxyethoxy)phenylamino)pyrimidin-4-ylamino)phenyl)acrylamide benzenesulfonic acid salt) for the treatment of B-cell chronic lymphocytic leukemia (CLL). Spebrutinib (as research code CC-292) has been compared with placebo as a co-therapy with methotrexate for active rheumatoid arthritis, in completed clinical trial NCT01975610. In addition it is in various Phase I trials for B-cell lymphomas. Click here to view these trials at ClinicalTrials.gov.
Immuno Disease Comments: Phase 1 clinical candidate for B cell malignancies (see NCT01732861).
Clinical Use: Bafetinib has been assessed in two completed Phase II clinical trials for hormone-refractory prostate cancer (NCT01215799) and relapsed or refractory B-cell chronic lymphocytic leukemia (CLL; NCT01144260).
Both the US FDA and EMA have granted bafetinib orphan drug status for the treatment of Philadelphia chromosome-positive CML.
Immuno Disease Comments: FDA and EMA orphan drug for Philadelphia chromosome-positive CML. Phase 2 clinical trial in B cell CLL has been completed (see NCT01144260).
Clinical Use: GDC-0853 has reached Phase 2 clinical trial in patients with rheumatoid arthritis (RA: see NCT02833350), and Phase 1 in patients with resistant B-cell lymphoma or chronic lymphocytic leukemia (CLL).
Immuno Disease Comments: Phase 2 clinical candidate for CLL (see NCT01991184).
