The primary objective of this study is to evaluate the safety and tolerability of TAK-981 as a single agent in participants with advanced or metastatic solid tumors or lymphomas.

Official Title

An Open Label, Dose-Escalation Phase I Study to Evaluate the Safety, Tolerability and Pharmacokinetics of TAK-981 in Adult Patients With Metastatic Solid Tumors or Lymphomas


The drug being tested in this study is called TAK-981. TAK-981 is being tested to evaluate safety, tolerability, and PK in participants who have locally advanced or metastatic solid tumors or relapsed or refractory lymphomas for whom there is no standard therapeutic alternative with established clinical benefit is available. The study will include a dose escalation phase and a dose expansion phase.

The study will enroll approximately 80 participants, approximately 40 to 50 participants in the dose escalation phase and approximately 15 participants in each of the 2 cohorts of dose expansion phase.

In the dose escalation phase, dose levels will be escalated based on safety, and available PK and pharmacodynamic data. This study will also determine the single agent recommended phase 2 dose (RP2D). Participants in dose expansion phase will be enrolled, once maximum tolerated dose (MTD) or biological effective dose (BED) is determined. One of the 2 cohorts in dose expansion phase will consist of participants with relapsed/refractory lymphomas, and other cohort will consist of participants with solid tumors with no standard therapeutic option available with established clinical benefit.

This multi-center trial will be conducted in the United States and Canada. The overall time to participate in this study is approximately 3 years. The overall time to receive treatment in this study is approximately 1 year. Based on decision of sponsor, participants with demonstrated clinical benefit can continue treatment beyond 1 year. Participants will make multiple visits to the clinic, and will make a final visit 30 days after receiving their last dose of drug or before the start of subsequent anticancer therapy, whichever occurs first for a follow-up assessment.

Open to people ages 18 years and up

  1. Adult male or female participants greater than or equal to (>=)18 years old.
  2. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
  3. Population for dose escalation and expansion.
  4. Has histologically confirmed advanced (local regionally recurrent not amenable to curative therapy) or metastatic solid tumors that have no standard therapeutic option with a proven clinical benefit, are intolerant or have refused them, OR
  5. Has relapsed/refractory lymphoma not amenable to therapies with proven clinical benefit or who are intolerant or who refuse them. Participants with low grade lymphomas such as follicular lymphoma, small lymphocytic lymphoma, lymphoplasmacytoid lymphoma, and marginal zone lymphomas, may not need to exhaust all available therapy. These participants can be enrolled after failure of at least 2 prior systemic therapies, provided that there is not an immediate need for cytoreduction. In these cases, participants who need immediate therapy for tumor bulk are not eligible for this trial.
  6. If enrolled before a dose level for which there is consistent evidence of TAK-981 pharmacodynamic effect (DLx) will not be required to have measurable disease. But once that DLx is determined, participants enrolling in dose escalation and expansion cohorts will be required to have measurable disease per RECIST version 1.1 for participants with solid tumors or RECIL 2017 for participants with lymphoma.
  7. Screening and post-dose tumor biopsies are required from all participants in the expansion cohorts and are optional during dose escalation, however once a DLx is identified at which there is clear evidence of TAK-981 biological effect (that is, observation of peripheral lymphopenia, induction of cytokines/chemokines, type 1 interferon (IFN) signature in blood, drug-related toxicity or antitumor effect), subsequent participants must agree in providing a fresh tumor biopsy during the screening period and a second tumor biopsy as requested in the schedule of events (SOE). The lesion accessible for biopsy may not be the only target lesion and should not be located in a previously irradiated field (unless this index lesion has progressive disease >=20% post radiation). Ideally, the same lesion should be biopsied before treatment and on treatment whenever possible.
  8. Adequate bone marrow reserve and renal and hepatic function.
  9. Recovered to Grade 1, baseline or established as sequela, from all toxic effects of previous therapy (except alopecia, neuropathy, or autoimmune endocrinopathies with stable endocrine replacement therapy).
  10. Left ventricular ejection fraction (LVEF) >=40 percent (%); as measured by echocardiogram or multiple gated acquisition scan (MUGA).
  11. Consented to undergo serial skin punch biopsies unless the sponsor decided that there are already enough biopsies for proper target engagement assessment.
  12. . Suitable venous access for safe drug administration and the study-required PK and pharmacodynamics sampling.
  13. . Women of child-bearing potential participating in this study should avoid becoming pregnant, and male participants should avoid impregnating a female partner. Nonsterilized female participants of reproductive age and male participants should use effective methods of contraception through defined periods during and after study treatment as specified below. Female participants must meet 1 of the following:
  14. Postmenopausal for at least 1 year before the screening visit, or
  15. Surgically sterile, or
  16. If they are of childbearing potential, agree to practice 1 highly effective method and 1additional effective (barrier) method of contraception at the same time, from the time of signing of the informed consent form (ICF) through 90 days after the last dose of study drug (whichever is longer), or
  17. Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the participant. (Periodic abstinence [example, calendar, ovulation, symptothermal, postovulation methods], withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception. Female and male condoms should not be used together.)
  18. . Male participants, even if surgically sterilized (that is, status postvasectomy) must agree to 1 of the following:
  19. Agree to practice effective barrier contraception during the entire study treatment period and through 120 days after the last dose of study drug, or
  20. Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the participant. (Periodic abstinence [example, calendar, ovulation, symptothermal, postovulation methods], withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception. Female and male condoms should not be used together.)
