  • Patients must have recurrent and/or disease not amenable to other curative intent therapy.
  • At least 4 weeks must have elapsed since the end of prior systemic treatment and/or 2 weeks since completion of radiotherapy with resolution of all treatment related toxicity to Version 5.0 grade \<1 (or tolerable grade 2) or back to baseline (except for alopecia, lymphopenia, or hypothyroidism) prior to starting study drug treatment.
  • Patients must have V1.1 , defined as at least one nonnodal lesion measuring ≥ 20 mm with conventional techniques or as ≥10mm with CT scan, MRI, or calipers by clinical exam in the longest dimension AND/OR a nodal lesion measuring ≥ 15 mm in the shortest dimension. Tumors in previously irradiated fields may be considered measurable if there is evidence of tumor progression after radiation treatment.
  • Patients must have documentation of a new or progressive lesion on radiologic imaging study performed within 6 months prior to study enrollment (progression of disease over any interval is allowed) and/or new/worsening disease related symptoms within 6 months prior to study enrollment. Note: This assessment will be performed by the treating investigator and evidence of progression by RECIST criteria is not required.
  • Age ≥ 18 years of age on the day of signing .
  • performance status 0 or 1 (or ≥ 70%).
  • Patients must have tissue from the primary tumor or metastases available for correlative studies. Either a paraffin block or at least 20 unstained slides are acceptable (paraffin block or at 30 unstained slides would be ideal). Patients without available tissue for submission may still be eligible if approved by the Principal Investigator. Additional tissue collection is not a requirement for this study.
  • Screening laboratory values must meet the following criteria:

    • Neutrophils ≥ 1500/μL
    • ≥ 100x10\^3/μL
    • > 9.0 g/dL (without packed red blood cell (pRBC) transfusion within the last 2 weeks)
    • and ALT ≤ 2.5 x (if liver metastases are present, AST and ALT ≤ 5x ULN)
    • Total ≤ 1.5 x ULN OR direct bilirubin ≤ ULN for participants with total bilirubin levels >1.5 x ULN (except participants with Gilbert Syndrome, who can have a total bilirubin \< 3.0 mg/dL)
    • Serum creatinine ≤ 1.5 x ULN OR (CrCl) ≥ 40 mL/min per the Cockcroft-Gault formula if creatinine is >1.5 x ULN
    • Female CrCl = (140 - age in years) x weight in kg x 0.85 72 x serum creatinine in mg/dL
    • Male CrCl = (140 - age in years) x weight in kg x 1.00 72 x serum creatinine in mg/dL
  • Participants must be willing to sign the written informed consent form. A signed informed consent form must be appropriately obtained prior to the conduct of any trial specific procedure.
  • Male participants must agree to use adequate and refrain from donating sperm from start of therapy through 4 months after last dose of trial treatment.
  • Female participants must agree not to donate ova starting at screening and throughout the study period, and for at least 3 weeks after the final dose of study drug.
  • A female participant is eligible to participate if 1) she is not pregnant (for women of , a pregnancy test must be negative within 72 hours prior to initiation; if a urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required) OR 2) she is not a woman of child bearing potential as defined by one of the following criteria:

    • Pre-menopausal with one of the following: documented hysterectomy, documented bilateral salpingectomy, documented bilateral oophorectomy
    • females defined as no menses for 12 months without an alternative medical cause. However, in the absence of 12 months of amenorrhea, confirmation with two FSH measurements in the postmenopausal range is required.
  • A woman of childbearing potential must use highly effective contraception from the start of therapy through 2 months after the last dose of study medication.

Exclusion criteria

Exclusion Criteria:

  • Untreated (subjects with treated brain metastases will be eligible, provided that they are radiographically stable, i.e. without evidence of progression for at least 4 weeks by repeat imaging [note that the repeat imaging should be performed during study screening], clinically stable and without requirement of treatment for at least 14 days prior to the first dose of study treatment).
  • Prior if diagnosed and treated within 2 years of trial drug initiation. Patients may be included if they have completed therapy for a prior malignancy >2 years prior to drug initiation and are currently no evidence of disease (NED). Exception: Participants with non-melanoma skin cancer or carcinoma in situ (breast DCIS, or cervical CIS) that have undergone potentially curative therapy at any time are not excluded from trial participation.
  • Prior systemic anti-cancer therapy within 4 weeks of start of study treatment.
  • ≥ Grade 2 peripheral neuropathy per v5.0 criteria.
  • Dry eyes, keratitis, keratopathy, and active conjunctivitis.
  • congestive heart failure of grade II or above, unstable angina, myocardial infarction within the past 6 months, or serious cardiac arrhythmia associated with significant cardiovascular impairment within the past 6 months (baseline echocardiogram is not required unless clinically indicated).
  • Active infection, defined as any infection requiring systemic treatment
  • Subject is known to be positive for (HIV) or active Virus (HCV) or active (HBV) infection (positive viral load). Testing for HIV, HCV, or HBV prior to initiation of the study drug is not required. If patient's have a known history of treated HCV, then a viral load is required to confirm clearance of infection.
  • Has a history of (non-infectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
  • Renal failure requiring active hemo- or peritoneal dialysis.
  • Breast feeding is not allowed from the start of treatment through 3 weeks after the last dose of study drug.
  • Has a history or current evidence of any medical or other condition, therapy or laboratory abnormality which, in the opinion of the investigator, might confound the results of the study, or preclude participation in a clinical study.
Terms in these criteria, in plain language(24)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

CTCAE grade

The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.

1
Mild.
2
Moderate.
3
Severe.
4
Life-threatening.
5
Death due to the event.

“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.

RECIST

The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.

“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
