Study summary

This phase I/Ib trial tests the safety and best dose of ipatasertib in combination with the usual treatment approach using chemotherapy together with radiation therapy ("chemo-radiation") in patients with head and neck cancer. Ipatasertib is in a class of medications called protein kinase B (AKT) inhibitors. It may stop the growth of tumor cells and may kill them. Cisplatin, which is a chemotherapy used in this trial, is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Radiation therapy uses high energy to kill tumor cells and shrink tumors. Giving ipatasertib in combination with chemo-radiation may be better than chemo-radiation alone in treating patients with advanced head and neck cancer.

Read the detailed description

PRIMARY OBJECTIVE:

I. To determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of ipatasertib in combination with definitive chemoradiation in locally advanced head and neck squamous cell carcinoma (HNSCC) based on dose-limiting toxicities (DLTs).

SECONDARY OBJECTIVES:

I. To assess acute and late toxicities, based on Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.

II. To assess long-term swallowing function, based on gastric tube dependency at 6 and 12 months that is different from baseline.

III. To determine duration and completion rate of prescribed radiation and chemotherapy.

IV. To determine pharmacokinetic profile of ipatasertib in combination with cisplatin and radiation therapy, based on peak and trough blood levels in patients administered ipatasertib orally.

V. To determine pharmacodynamic effects of ipatasertib at the MTD, based on pAKT, pS6 and pPRAS40 as markers of AKT pathway inhibition, and gamma-H2AX as a marker of radiosensitization.

VI. To observe and record anti-tumor activity (objective response rate by Response Evaluation Criteria in Solid Tumors [RECIST] criteria, locoregional control, relapse-free survival, and overall survival) of the combination of ipatasertib, cisplatin, and radiation therapy in patients with HNSCC.

VII. To correlate efficacy outcomes with tumor genotype, based on whole exome sequencing of pre-treatment biopsy specimens.

OUTLINE: This is a phase I, dose-escalation study of ipatasertib in combination with fixed-dose cisplatin and radiation therapy followed by a dose-expansion study.

DOSE ESCALATION:

Patients receive ipatasertib orally (PO) once daily (QD) or Monday, Wednesday, and Friday depending on dose level on days 1-28 of each cycle. Patients also receive cisplatin intravenously (IV) weekly on day 1 of cycle 1, weeks 1-4 and day 1 of cycle 2, weeks 1-3 for 7 doses. Patients undergo radiation therapy (RT) daily (Monday-Friday) for 35 fractions during weeks 1-7. Treatment repeats every 28 days for a total of 2 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo positron emission tomography (PET)/computed tomography (CT), CT, or magnetic resonance imaging (MRI) during screening, follow-up, and as clinically indicated. Patients undergo blood sample collection on trial.

DOSE EXPANSION:

Patients receive ipatasertib PO MTD on days 2-28 or 3-28 of cycle 1 and 1-28 of subsequent cycles. Patients also receive cisplatin IV weekly on day 1 of cycle 1, weeks 1-4 and day 1 of cycle 2, weeks 1-3 for 7 doses. Patients undergo RT daily (Monday-Friday) for 35 fractions during weeks 1-7. Treatment repeats every 28 days for a total of 2 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo PET/CT, CT, or MRI during screening, follow-up, and as clinically indicated. Patients undergo blood sample collection and tumor biopsy on trial.

After completion of study treatment, patients are followed for 30 days and then every 3 months for up to 2 years.

Exclusion criteria

Exclusion Criteria:

  • Primary tumor of nasopharynx, salivary, thyroid or parathyroid glands, or skin
  • Distant from the current HNSCC
  • Prior treatment (e.g., chemotherapy, radiation, or definitive surgery) for the current locally advanced HNSCC is not permitted. , including those performed under anesthesia, are not considered surgery. Patients who underwent prior definitive surgery alone for an early stage (T1-2N0) HNSCC which has now recurred with stage III-IVB disease at least 3 months after the initial surgery are eligible
  • For patients with a prior history of another , no prior chemotherapy or radiation may have been administered within 6 weeks prior to study entry. Among patients who received prior radiation to the head and neck or adjacent anatomical site for another malignancy, there may be no overlap with current area to be irradiated
  • Current use of any other agents

  • Treatment with strong inhibitors or inducers of or P-glycoprotein within 2 weeks or 5 drug-elimination half-lives, whichever is longer, prior to initiation of study drug. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/ procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
  • Patients with uncontrolled intercurrent illness, including active infection
  • Pregnant women are excluded from this study because ipatasertib is an oral AKT inhibitor 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 ipatasertib, breastfeeding should be discontinued if the mother is treated with ipatasertib. These potential risks may also apply to other agents used in this study
  • Patients with type I or type II diabetes mellitus requiring insulin at study entry. Patients with non-insulin dependent type II diabetes mellitus are eligible, as are patients who are on a stable dose of oral diabetes medication >= 4 weeks prior to initiation of study treatment.

  • Lung disease: pneumonitis, interstitial lung disease, idiopathic pulmonary fibrosis, cystic fibrosis, aspergillosis, active tuberculosis, or history of opportunistic infections (pneumocystis pneumonia or cytomegalovirus pneumonia)
  • Known history of liver disease consistent with Class B or C, including active viral or other hepatitis (e.g., positive for surface antigen [HBsAg] or virus [HCV] antibody at screening), or cirrhosis
  • Grade >= 2 uncontrolled or untreated hypercholesterolemia (cholesterol > 300 mg/dL or > 7.75 mmol/L) or hypertriglyceridemia (triglycerides > 300 mg/dL or > 3.42 mmol/L)
Terms in these criteria, in plain language(27)

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.

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.

Metastases

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

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.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

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.

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).

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.

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.

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.

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.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

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.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

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 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.

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.

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.

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.

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.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

CYP3A (CYP3A4) inhibitors and inducers

CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

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.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

What researchers measure

Primary outcomes

  1. Maximum tolerated dose (MTD) and recommended phase 2 dose of ipatasertib in combination with definitive chemo-radiation

    Patients who receive at least 70% of the prescribed course of ipatasertib on radiation days will be evaluable for dose limiting toxicity assessment. After the escalation phase of the trial is completed, the MTD will be selected using the pooled-adjacent-violators algorithm, a type of isotonic regression, as specified in Liu and Yuan (2015).

    Time frame: At the completion of dose escalation phase, up to 56 days from treatment start date

Secondary outcomes

  1. Acute and late toxicities

    Will be assessed according to Common Terminology Criteria for Adverse Events version 5.0. Toxicities occurring \> 90 days from the end of radiation will be considered late toxicities. This will include assessment of long-term swallowing function, based on gastric tube dependency at 6 and 12 months as compared to baseline due to the effects of the primary tumor. Descriptive statistics will be used to summarize these toxicities.

    Time frame: From 90 days after the end of radiation treatment up to 1 year from treatment completion date

  2. Duration and completion rate of prescribed radiation and chemotherapy

    Descriptive statistics will also be used to summarize the duration and completion rate of prescribed radiation and chemotherapy.

    Time frame: Up to 2 years

  3. Objective response rate

    Assessed based on Response Evaluation Criteria in Solid Tumors, as well as locoregional control, relapse-free survival, and overall survival. Two-sample t-test, Mann-Whitney U test, or log rank test will be used where appropriate to analyze the correlation between efficacy outcomes and pre-treatment genotypic abnormalities in the AKT pathway based on whole exome sequencing and PTEN immunohistochemistry (IHC).

    Time frame: Up to 2 years

  4. Pharmacokinetic (PK) profile of ipatasertib in combination with cisplatin

    Will be assessed using peak and trough blood levels in patients administered ipatasertib orally during weeks 2 and 3 of study treatment. The combined therapy will be compared to historical PK data for drug alone, in order to assess for a drug-drug interaction.

    Time frame: Up to 2 years

  5. Pharmacodynamic effects of ipatasertib

    Based on pAKT, pS6 and PRAS40 as markers of AKT pathway inhibition, and gamma-H2AX as a marker of radiosensitization. Two-sample t-test and Mann-Whitney U test will be used where appropriate to compare values before and after the addition of ipatasertib to chemoradiation.

    Time frame: Up to 2 years

  6. Locoregional control

    Two-sample t-test, Mann-Whitney U test, or log rank test will be used where appropriate to analyze the correlation between efficacy outcomes and pre-treatment genotypic abnormalities in the AKT pathway based on whole exome sequencing and PTEN IHC.

    Time frame: From start of treatment to cancer recurrence at the site of the primary tumor or the regional lymph nodes, assessed up to 2 years

  7. Relapse-free survival

    Two-sample t-test, Mann-Whitney U test, or log rank test will be used where appropriate to analyze the correlation between efficacy outcomes and pre-treatment genotypic abnormalities in the AKT pathway based on whole exome sequencing and PTEN IHC.

    Time frame: From start of treatment to the time of cancer recurrence or death, whichever occurs first, assessed up to 2 years

  8. Overall survival

    Two-sample t-test, Mann-Whitney U test, or log rank test will be used where appropriate to analyze the correlation between efficacy outcomes and pre-treatment genotypic abnormalities in the AKT pathway based on whole exome sequencing and PTEN IHC.

    Time frame: From the start of treatment that patients are still alive, assessed up to 2 years

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.
No changes since tracking began. The registry record was last updated on Sep 22, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
