Plain English summary of protocol
Background and study aims
Relapsed or refractory multiple myeloma (MM) is a blood cancer that forms in a type of white blood cells (WBC) called plasma cells. Drugs that activate T-cells (a type of WBC) to attack cancer cells may be an effective way to destroy them. Cancer is called relapsed if it comes back after treatment and is called ‘refractory’ if does not respond to treatment. Talquetamab (JNJ-64407564) binds to proteins called cluster of differentiation 3 (CD3) receptor, found on T-cells and G protein-coupled receptor family C group 5 member D (GPRC5D), found on myeloma cells. This activates the T-cells and leads to the killing of myeloma cells. In this study, researchers want to learn how preventive measures started before the first dose of talquetamab and continued throughout the treatment phase may reduce the number, intensity, or length of time for oral taste changes incidents related to talquetamab compared to no preventive measures for oral taste changes. This study aims to assess preventive measures for the side effects of an approved myeloma therapy (talquetamab).
Who can participate?
Male and female healthy participants 18 years or older with relapsed or refractory MM who have disease progression after receiving at least 1 of each of the following medication classes. PI, IMIDs, and anti-CD38 mAb.
What does the study involve?
The study will be conducted as:
1. Screening (Up to 28 days): Confirm if the participants can take part in the study.
2. Treatment Phase (Up to 12 months)*: Participants will be divided into either of the 4 treatment groups in a random way to receive the treatment:
• Cohort A (control): Talquetamab as an injection under the skin
• Cohort B: Prophylaxis mouth wash plus talquetamab
• Cohort C: Prophylaxis by mouth plus talquetamab
• Cohort D: Prophylaxis by mouth plus talquetamab
*Prophylaxis Treatment Phase duration could be longer than 12 months, if there are clinical benefits relevant to the participant and part of the objectives of the study, at treating physician’s discretion.
Talquetamab Treatment Phase: Until disease progression, death, talquetamab treatment discontinuation for any other reason (e.g. unacceptable toxicity, withdrawal of consent), or end of study, whichever occurs first.
3. Follow-up Phase (Up to approximately 12 months): Participants will be followed up for their overall health throughout the study.
During the study, some tests such as blood and urine tests, neurological examination, and physical examination will be performed. Side effects will be recorded until the study ends (Up to 12 to 30 months).
What are the possible benefits and risks of participating?
Taking talquetamab may or may not improve multiple myeloma. The benefit to study participants receiving talquetamab in this study cannot be guaranteed.
Participants may experience some benefit from participation in the study that is not due to receiving talquetamab but rather is due to regular visits and assessments monitoring overall health. Participation in the study may help other people with multiple myeloma in the future.
Participants may have side effects from the drug(s) or procedures used in this study that may be mild to severe and even life-threatening, and they can vary from person to person. The most common, known risks are getting symptoms such as cytokine release syndrome (CRS), cytopenias, skin and nail changes, oral side-effects, infection, injection-site reactions, and increased risk for immune effector cell-associated neurotoxicity syndrome (ICANS). The participant information sheet and informed consent form, which will be signed by every participant agreeing to participate in the study, includes a detailed section outlining the known risks of participating in the study. Not all possible side effects and risks related to talquetamab are known at this moment. During the study, the sponsor may learn new information about talquetamab. The study doctor will tell participants as soon as possible about any new information that might make them change their minds about being in the study, such as new risks.
To minimise the risk associated with taking part in the study, participants are frequently looked at and asked about any side effects and other medical events. Participants are educated to report any such events to the study doctor who will provide appropriate medical care. Any serious side effects that are reported to the sponsor are thoroughly reviewed by a safety team. There are no costs to participants to be in the study. The sponsor will pay for the study drug and tests that are part of the study. The participant will receive reasonable reimbursement for study-related costs (for example, travel/parking costs).

| Scientific title | A phase II, open-label, randomized study to evaluate prophylactic interventions on talquetamab-related oral toxicity |
| Study acronym | TALISMAN |
| Study objectives | Primary objectives: 1. To find preventive measures that can reduce number, intensity, and length of time for taste change incidents related to talquetamab during treatment phase. 2. To better understand the signs and symptoms of taste changes related to talquetamab. Secondary objectives: 1. To find out the impact of preventive measures on problems with sense of taste. 2. To assess harmful effects in the mouth due to treatment-related side effects. 3. To assess quality of life parameters related to overall health and specific impact of taste changes, xerostomia (dry mouth), dysphagia (difficulty swallowing), oral mucositis (mouth ulcers), and other harmful effects in mouth. 4. To assess the impact of preventive measures on change in body weight. 5. To assess participants’ ability to follow the talquetamab treatment schedule. 6. To assess the impact of preventive measures on smell function. 7. To determine how well (efficacy) talquetamab works. 8. To determine safety of talquetamab and preventive measures. |

| Intervention | Cohort A: Talquetamab. Participants with relapsed or refractory multiple myeloma (RRMM) (previously exposed to at least 1 proteasome inhibitor (PI), 1 immunomodulatory drug(s) [IMiD]), and an anti-CD38 monoclonal antibody [mAb]) will be treated with talquetamab subcutaneously until progressive disease, death, lost to follow-up, withdrawal of consent, discontinuation because of toxicity, or until 12 months after the start of talquetamab treatment, whichever occurs first. Cohort B: Prophylaxis A and Talquetamab. Participants with RRMM (previously exposed to at least 1 PI, 1 IMiD, and an anti-CD38 mAb) will receive prophylaxis A along with talquetamab therapy. Participants will start the assigned prophylaxis 1 week before starting talquetamab treatment. After step-up dosing of talquetamab therapy, participants will be treated with talquetamab until progressive disease, death, lost to follow-up, withdrawal of consent, discontinuation because of toxicity, or until 12 months after the start of talquetamab treatment, whichever occurs first. Cohort C: Prophylaxis B and Talquetamab. Participants with RRMM (previously exposed to at least 1 PI, 1 IMiD, and an anti-CD38 mAb) will receive prophylaxis B along with talquetamab therapy. Participants will start the assigned prophylaxis 1 week before starting talquetamab treatment. After step-up dosing of talquetamab therapy, participants will be treated with talquetamab until progressive disease, death, lost to follow-up, withdrawal of consent, discontinuation because of toxicity, or until 12 months after the start of talquetamab treatment, whichever occurs first. Cohort D: Prophylaxis C and Talquetamab. Participants with RRMM (previously exposed to at least 1 PI, 1 IMiD, and an anti-CD38 mAb) will receive prophylaxis C along with talquetamab therapy. Participants will start the assigned prophylaxis 1 week before starting talquetamab treatment. After step-up dosing of talquetamab therapy, participants will be treated with talquetamab until progressive disease, death, lost to follow-up, withdrawal of consent, discontinuation because of toxicity, or until 12 months after the start of talquetamab treatment, whichever occurs first. |
