Study summary

This Phase III randomized controlled trial evaluates the effectiveness and toxicity profile of a modified DHAP regimen compared to the standard DHAP regimen in adult patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). The DHAP regimen (cisplatin, cytarabine, dexamethasone) is widely used as salvage therapy but is associated with significant toxicities, including renal dysfunction and severe myelosuppression. The modified DHAP protocol fractionates cisplatin and cytarabine administration to reduce nephrotoxicity, improve tolerability, and potentially allow outpatient treatment.

A total of 74 patients will be randomized (37 per arm) to receive either the modified or standard DHAP regimen. The primary endpoint is overall response rate (ORR) assessed by RECIL 2017 criteria. Secondary endpoints include progression-free survival (PFS), toxicity incidence and severity graded by CTCAE, and quality of life measured by EORTC QLQ-C30.

The study anticipates that the modified DHAP regimen will demonstrate comparable or superior efficacy with reduced severe toxicities, shorter hospital stays, and improved patient satisfaction. Findings may support transitioning DHAP into outpatient administration, optimizing healthcare resource utilization in Pakistan.

Read the detailed description

This study is a randomized controlled trial designed to compare the effectiveness and toxicity profile of a modified DHAP regimen versus the standard DHAP regimen in adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL).

DLBCL is the most common subtype of non-Hodgkin lymphoma, with a significant proportion of patients experiencing relapse or refractory disease after initial therapy. The standard DHAP regimen (cisplatin, cytarabine, dexamethasone) has been widely used as salvage therapy, achieving response rates of up to 70%. However, its use is limited by severe toxicities, including renal dysfunction, infections, and profound myelosuppression.

The modified DHAP regimen alters the administration schedule of cisplatin and cytarabine. Cisplatin is fractionated into smaller doses over multiple days rather than a single 24-hour continuous infusion, and cytarabine is administered over two consecutive days. This modification is hypothesized to reduce nephrotoxicity, improve tolerability, and allow outpatient administration, while maintaining or enhancing cytotoxic synergy between cisplatin and cytarabine.

A total of 74 patients will be enrolled and randomized into two arms (37 per arm):

  • Arm A (Modified DHAP): Dexamethasone 40 mg PO/IV days 1-4; Cisplatin 50 mg/m² over 6 hours days 1-2; Cytarabine 2 g/m² IV over 3 hours days 1-2.
  • Arm B (Standard DHAP): Dexamethasone 40 mg PO/IV days 1-4; Cisplatin 100 mg/m² continuous infusion over 24 hours day 1; Cytarabine 2×2 g/m² IV over 3 hours day 2.

Primary endpoint: Overall response rate (ORR), defined as complete or partial response per RECIL 2017 criteria.

Secondary endpoints: Progression-free survival (PFS), toxicity incidence and severity graded by CTCAE, and quality of life (QoL) assessed using the EORTC QLQ-C30 questionnaire.

Patients will be followed for treatment response, adverse events, and QoL changes. Toxicities will be documented using CTCAE forms, with particular attention to hematological toxicities (anemia, neutropenia, thrombocytopenia) and non-hematological toxicities (renal dysfunction, hepatotoxicity, mucositis, neuropathy).

The study anticipates that the modified DHAP regimen will demonstrate comparable or superior efficacy with a reduced incidence of severe toxicities, shorter hospital stays, and improved patient satisfaction. If successful, this regimen could support the transition of DHAP into outpatient administration, optimizing healthcare resource utilization in Pakistan and improving access to therapy for patients with poor prognoses.

Terms in these criteria, in plain language(13)

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.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

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.

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.

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.

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.

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.

Metastases

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

Primary outcomes

  1. Overall Response rate (ORR)

    The Overall Response Rate (ORR) is defined as the percentage of patients achieving either a Complete Response (CR) or a Partial Response (PR), assessed according to RECIL 2017 criteria. * Complete Response (CR): * Disappearance of all target lesions * Lymph nodes \<10 mm * Normalization of FDG-PET (Deauville 1-3) * No bone marrow involvement, no new lesions * Partial Response (PR): * ≥30% decrease in the sum of longest diameters of target lesions * FDG-PET positive (Deauville 4-5) * May still have bone marrow involvement * No new lesions

    Time frame: From enrollment to the end of treatment at 12 weeks

Secondary outcomes

  1. Complete Response (CR)

    * Complete Response (CR): * Disappearance of all target lesions * Lymph nodes \<10 mm * Normalization of FDG-PET (Deauville 1-3) * No bone marrow involvement, no new lesions

    Time frame: From enrollment to the end of treatment at 12 weeks

  2. Partial Response (PR)

  5. Progressive Disease

    * \>20% increase in the sum of longest diameters of target lesions * For small lymph nodes (\<15 mm post-therapy), a minimum absolute increase of 5 mm and long diameter \>15 mm is required * Appearance of new lesions automatically qualifies as PD * Any FDG-PET finding consistent with progression * Bone marrow involvement may persist or newly appear

    Time frame: From enrollment to the end of treatment at 12 weeks

  6. Progression free Survival (PFS)

    the time from randomization (or study entry) until objective disease progression or death from any cause, whichever occurs first as assessed using standardized tumor response criteria (RECIL)
