  • Participants must have at least one measurable site of disease per RECIST version 1.1. This is defined as a lesion that can be accurately measured in at least one dimension (longest diameter to be recorded). For non-lymph node tumor lesions, they must be a minimum size of ≥ 10 mm. For malignant lymph node lesions, they must be at least ≥ 15 mm in short axis with conventional techniques or ≥10 mm with more sensitive techniques such as MRI or spiral CT scan. If the participant has had previous radiation to the marker lesion(s), there must be evidence of progression since the radiation.
  • ECOG performance status ≤2
  • Age ≥ 18 years
  • Participants must have adequate organ and marrow function prior to study entry as defined below:
  • INR and PT ≤ 1.5 x ULN and partial prothrombin time (PTT) or activated partial thromboplastin time (aPTT) ≤1.5 ULN (unless abnormalities are unrelated to coagulopathy). Therapeutic anticoagulation is permitted if: on a stable dose of low molecular weight heparin (LMWH) for > 2 weeks (14 days) at the time of enrollment or on a direct oral anticoagulant (DOAC) for > 2 weeks at time of enrollment.
  • Participants with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, participants should be class 2B or better.
  • For participants with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated.
  • Participants with a history of hepatitis C virus (HCV) infection must have been treated and cured. For participants with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load. Patients who are Hepatitis C virus antibody positive (HCV Ab
  • +) who have controlled infection (undetectable HCV RNA by PCR either spontaneously or in response to a successful prior course of anti-HCV therapy) are permitted.
  • Participants with a history of major psychiatric illness must be judged (by the treating physician) able to fully understand the investigational nature of the study and the risks associated with the therapy.
  • The effects of Ivonescimab on the developing human fetus are unknown. For this reason, 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 8years of age) and 55 years unless the participants presents with an applicable exclusionary factor which may be one of the following: i. Postmenopausal (no menses in greater than or equal to 12 consecutive months). ii. History of hysterectomy or bilateral salpingo-oophorectomy. iii. Ovarian failure (Follicle Stimulating Hormone and Estradiol in menopausal range, who have received Whole Pelvic Radiation Therapy). iv. History of bilateral tubal ligation or another surgical sterilization procedure.
  • Female participants of childbearing potential (not postmenopausal for at least 12 months and not surgically sterile) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) before study entry. Pregnancy test must be repeated on the day of first infusion, if test performed > 14 days before starting study drug.
  • Female participants of childbearing potential having sex with an unsterilized male partner must agree to use a highly effective method of contraception from the beginning of screening until 90 days after the last dose of the ivonescimab. Unsterilized male patients having sex with a female partner of childbearing potential, or a pregnant or breastfeeding partner must agree to use barrier contraception (male condom) for the duration of the treatment period until 90 days after the last dose of ivonescimab. Male patients with female partners of childbearing potential must have the female partner agree to use at least 1 form of highly effective contraception for the duration of the treatment period until 90 days after the last dose of ivonescimab.
  • 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, Subject/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.
  • Ability to understand and the willingness to sign a written informed consent document for this clinical trial and the companion Trials LAB02-152 and PA17-0577

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ivonescimab in people with Ivonescimab and Clear Cell Renal Carcinoma, 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 22 inclusion and 34 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 20 Aug 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 (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 NCT06940518.

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 20 Aug 2026.
