Study summary

To find out if the combination of HC-7366 and nivolumab (with or without ipilimumab) can help to control ccRCC. The

Read the detailed description

Primary Objectives

To assess two combinations of HC-7366:

  • Doublet Cohort: HC-7366 with nivolumab monotherapy
  • Triplet Cohort: HC-7366 with nivolumab/ipilimumab dual immune checkpoint inhibition

    • For safety through assessment of trial-limiting toxicities including need for high dose corticosteroids (= 40 mg prednisone equivalents for two weeks or more)
    • For antitumor activity through assessment of Overall response rate (ORR) and Disease control rate (DCR: CR or partial response (PR) or stable disease (SD)) per RECIST v1.1

Secondary Objectives The secondary objectives of the study are to estimate median progression free survival (mPFS) and PFS at six months, duration of response (DOR), primary PD rate (progressive disease as best response), Time to response (TTR), overall survival (OS) median and at one year, immune related Adverse Event (irAE) rate, and to evaluate participant reported outcomes using the FKSI-23 and the FACT-ICM Subscale.

  7. (ECOG) performance status of 0 or 1 )
  8. At least one as defined by 1.1

    • A tumor lesion situated in a previously irradiated area is considered a measurable/target lesion only if subsequent disease progression has been documented in the lesion
  9. Has pathology-confirmed RCC. Extra tissue should be submitted if available for correlatives. Formalin-fixed paraffin-embedded tissue blocks are preferred to slides. Details pertaining to tumor tissue submission can be found in the Lab Procedures Manual.
  10. Willing and able to undergo bone and brain scans at baseline and continue to have scans performed if positive at screening.

    • (ALT) and aspartate aminotransferase (AST) ≤ 3 x ULN
  12. Women must not be breastfeeding while taking the study drug and for up to five months after the last dose of study drug
  13. Women of (WOCBP) must have a negative serum or urine pregnancy test within 24 hours prior to receiving first dose of protocol-indicated treatment

    • "Women of childbearing potential" (WOCBP) is defined as any female who has experienced menarche who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or is not
    • Menopause is defined clinically as 12 months of amenorrhea in a woman over 45 years of age in the absence of other biological or physiological causes
    • If menopausal status is considered for the purpose of evaluating childbearing potential, women \< 62 years of age must have a documented serum follicle stimulating hormone (FSH) level within laboratory reference range for postmenopausal women, in order to be considered postmenopausal and not of childbearing potential
  14. Women of childbearing potential (WOCBP) must agree to follow instructions for acceptable prior to the study and from the time of signing consent, for the duration of the study participation and for 23 weeks after their last dose of protocol-indicated treatment

    • The effects of HC-7366 on the developing human fetus are unknown. For this reason and because first-in-class, first-in-human 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).
    • 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 study and the drug 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.
  15. Men not azoospermic who are sexually active with WOCBP must agree to follow instructions for acceptable contraception prior to the study and from the time of signing consent, for the duration of the study participation, and for 31 weeks after their last dose of protocol-indicated treatment
  16. Participant s with evidence of chronic virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
  17. Participant s with a history of 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
  18. Participant s with previously treated may be eligible provided they are radiologically (by MRI) and clinically stable (i.e., without evidence of disease progression) for at least 4 weeks (28 days) by repeat imaging (repeat imaging should be performed during study screening), with no evidence of new or enlarging brain metastases, and without requirement for treatment for at least 28 days prior to the first dose of study drug or study therapy. (CT is acceptable if MRI is )
  19. Participant s with a prior or concurrent whose natural history or treatment does not interfere with the safety or efficacy assessment of the regimen are eligible for this study
  20. Participant s 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 Functional Classification. To be eligible for this study, participant s should be class 2B or better

Exclusion Criteria

1. For the Triplet Cohort (Nivo/Ipi/HC-7366):

  • Prior systemic treatment including neoadjuvant or adjuvant therapy including an or TKI 2. For the Doublet Cohort (Nivo/HC-7366):
  • No more than 3 prior lines of systemic therapy allowed
  • Has received any type of small molecule kinase inhibitor (including investigational kinase inhibitor) ≤ 2 weeks before start of study drug or study therapy 3. ≤ 28 days before first dose of protocol-indicated treatment:
  • Major surgery requiring general anesthesia 4. ≤ 14 days before first dose of protocol-indicated treatment:
  • Radiosurgery or radiotherapy
  • Minor surgery. (Note: Placement of a vascular access device is not considered minor or major surgery)
  • Active infection requiring systemic treatment 5. Known or suspected active bleeding including active hemoptysis 6. Inability to swallow oral medication; or the presence of a poorly controlled gastrointestinal disorder that could significantly affect the absorption of oral study drug - e.g. Crohn's disease, ulcerative colitis, chronic diarrhea (defined as > 4 loose stools per day), malabsorption, or bowel obstruction 7. Central nervous system (CNS) metastasis, unless asymptomatic and radiologically (by MRI) and clinically stable (i.e., without evidence of disease progression) for at least 4 weeks (28 days) by repeat imaging (repeat imaging should be performed during study screening), with no evidence of new or enlarging brain metastases, and without requirement for steroid treatment for at least 28 days prior to the first dose of study drug or study therapy. (CT is acceptable if MRI is contraindicated 8. Any condition requiring systemic treatment with either corticosteroids (> 10 mg/day prednisone or equivalent daily) or other medications within 14 days prior to initiating protocol-indicated treatment
  • In the absence of active disease: Subjects are permitted the use of corticosteroids with minimal systemic absorption (e.g. topical, ocular, intraarticular, intranasal, and inhalational) ≤ 10 mg/day prednisone or equivalent daily; and physiologic replacement doses of systemic corticosteroids ≤ 10 mg/day prednisone or equivalent daily (e.g. hormone replacement therapy needed in participants with hypophysitis) 9. Active, known or suspected autoimmune disease
  • Subjects with type I diabetes mellitus; hypothyroidism only requiring hormone replacement; skin disorders such as vitiligo, psoriasis or alopecia not requiring systemic treatment; or conditions not expected by the investigator to recur in the absence of an external trigger are permitted to enroll 10. Known psychiatric condition, social circumstance, or other medical condition reasonably judged by the investigator to unacceptably increase the risk of study participation; or to prohibit the understanding or rendering of informed consent or anticipated compliance with and interpretation of scheduled visits, treatment schedule, laboratory tests and other study requirements 11. Pregnant women are excluded from this study because HC-7366 is novel, first-in-class small molecule agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with HC-7366, breastfeeding should be discontinued if the mother is treated with HC-7366. These potential risks may also apply to other agents used in this study 12. (HIV)-infected participants on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this study 13. Participants who are receiving any other investigational agents
Terms in these criteria, in plain language(31)

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.

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.

Metastases

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

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

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.

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.

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.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

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).

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.

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.

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.

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.

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).

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.

Washout period

A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.

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.

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.

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.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

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.

PD-1, PD-L1 and checkpoint inhibitors

PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.

PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

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.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
