  • NOTE: If participant is unable to walk due to paralysis, but is mobile in a wheelchair, participants considered to be ambulatory for the purpose of assessing their performance status.
  • Age (at the time of consent/assent): . 18 years
  • Consent to MD Anderson companion laboratory protocols LAB02-152, PA17-0577 and PA11-1045.
  • Participants must have adequate organ and marrow function as defined below:
  • Hemoglobina ≥9 g/dl (treatment allowed) Absolute neutrophil countb ≥1,500/.L Platelets ≥100,000/.L Total bilirubin ≤1.5 mg/dl AST(SGOT) or ALT (SGPT) ≤2.5 X institutional ULN,except in known hepatic metastasis, wherein may be ≤5 x ULN Estimated GFR (eGFR) >30 mL/kg/1.73 m2 by Cockcroft- Gault methods or local institutional standard Coagulation: INR or PT aPTT ≤ 1.5 x ULN unless participant is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants May receive transfusion within the screening period Without growth factor support (filgrastim or pegfilgrastim) for at least 14 days
  • Participants with controlled brain metastases are allowed on protocol if the brain metastases were surgically resected or treated with radiosurgery or Gamma knife, and are radiologically stable without recurrence or edema for at least 1 month (4 weeks) as confirmed by repeat imaging performed during study screening. Participants actively requiring glucocorticoids for uncontrolled brain or leptomeningeal metastases are not eligible.
  • Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [HCG]) within 24 hours prior to the start of the study drug.
  • Women must not be breastfeeding.
  • WOCBP must agree to follow instructions for method(s) of contraception from the time of registration for treatment for the duration of treatment with study drug (s) plus 5 half-lives of study drug (s) plus 30days (duration of ovulatory cycle) for a total of 5 months post treatment completion. Men must agree to effective contraception from the time of registration for treatment to 210 days post last protocol treatment.
  • Investigators shall counsel WOCBP and male participants who are sexually active with WOCBP on the importance of pregnancy prevention and the implications of an unexpected pregnancy Investigators shall advise WOCBP and male participants who are sexually active with WOCBP on the use of highly effective methods of contraception. Highly effective methods of contraception have a failure rate of < 1% per year when used consistently and correctly. Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), Intrauterine device (IUD), Tubal Ligation or hysterectomy, Patient/Partner post vasectomy, Implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
  • Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 120 days after completion of sacituzumab tirumotecan administration:
  • Refrain from donating sperm
  • Uses a penile/external condom when having penile-vaginal intercourse with a nonparticipant of childbearing potential who is not currently pregnant PLUS partner use of an additional contraceptive metho as a condom may break or leak
  • The effects of sacituzumab tirumotecan on the developing human fetus are unknown. For this reason and because immunotherapy agents as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception(hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. (Refer to Pregnancy Assessment Policy MD Anderson Institutional Policy # CLN1114). This includes all female participants, between the onset of menses (as early as 8 years of age) and 55 years unless the participant presents with an applicable exclusionary factor which may be one of the following:
  • Postmenopausal (no menses in greater than or equal to 12 consecutive months).
  • History of hysterectomy or bilateral salpingo-oophorectomy.
  • Ovarian failure (Follicle Stimulating Hormone and Estradiol in menopausal range, who have received Whole Pelvic Radiation Therapy).
  • History of bilateral tubal ligation or another surgical sterilization procedure.
  • Ability to understand and the willingness to sign a written informed consent document.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Sacituzumab tirumotecan in people with Phase II and Sacituzumab, run by M.D. Anderson Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 25 inclusion and 28 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 24 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Pavlos Msaouel, MD (713-563-4585, pmsaouel@mdanderson.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety and adverse events (AEs). (time frame: Through study completion; an average of 1 year.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07438626.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Sep 2026.
