BEQALZI is indicated for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL) after at least two lines of systemic therapy, including a Bruton's tyrosine kinase (BTK) inhibitor.
This indication is approved under accelerated approval based on response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s) [see Clinical Studies (14.1)].
BEQALZI dosing begins with a 4-week ramp-up. The ramp-up dosing schedule is designed to gradually reduce tumor burden (debulk) and decrease the risk of TLS.
Administer BEQALZI orally once daily, according to the ramp-up dosing schedule shown in Table 1.
Table 1. Dosing Schedule for 4-Week Ramp-Up Phase:
| Week Number | Days | Daily Dose | Number of Tablets per Dose |
| Week 1 | Days 1 to 3 | 1 mg | One 1 mg tablet |
| Days 4 to 7 | 2 mg | Two 1 mg tablets | |
| Week 2 | Days 1 to 3 | 5 mg | One 5 mg tablet |
| Days 4 to 7 | 10 mg | Two 5 mg tablets | |
| Week 3 | Days 1 to 3 | 20 mg | One 20 mg tablet |
| Days 4 to 7 | 40 mg | Two 20 mg tablets | |
| Week 4 | Days 1 to 3 | 80 mg | One 80 mg tablet |
| Days 4 to 7 | 160 mg | Two 80 mg tablets |
The Starter Pack provides the first 4 weeks of BEQALZI according to the ramp-up schedule [see How Supplied/Storage and Handling (16)].
After completion of the 4-week ramp-up phase, the recommended dosage of BEQALZI is 320 mg (four 80 mg tablets) taken orally once daily until disease progression or unacceptable toxicity.
Dosing after treatment interruption greater than 7 days is described in Table 3 [see Dosage Modifications for Adverse Reactions (2.3)].
Table 2 provides recommended BEQALZI dosage modifications for adverse reactions.
Table 3 provides temporary dose modifications upon restart after dose interruptions lasting more than 7 days.
Table 4 provides recommended modifications to the target dose after adverse reactions are resolved.

| Second and subsequent | Interrupt BEQALZI.b Upon recovery to Grade 1 or baseline level, resume BEQALZI and follow dose reduction guidelines in Table 3 and Table 4. | |
| Nonhematologic Toxicity | ||
| Grade 3 nonhematologic toxicityc | First | Interrupt BEQALZI. Upon recovery to Grade 1 or baseline level, resume BEQALZI at the same dose. |
| Second and subsequent | Interrupt BEQALZI.b Upon recovery to Grade 1 or baseline level, resume BEQALZI and follow dose reduction guidelines in Table 3 and Table 4. | |
| Grade 4 nonhematologic toxicity | First | Interrupt BEQALZI. Upon recovery to Grade 1 or baseline level, resume BEQALZI and follow dose reduction guidelines in Table 3 and Table 4. |
| Second and subsequent | Interrupt BEQALZI.b Upon recovery to Grade 1 or baseline level, resume BEQALZI and follow dose reduction guidelines in Table 3 and Table 4. | |
a Adverse reactions were graded using NCI CTCAE version 5.0.
b A maximum of 2 dose reductions is recommended.
c Patients may continue taking BEQALZI for the following:
* Grade 3 gastrointestinal toxicity (i.e., nausea, vomiting, diarrhea) unless unresponsive to treatment ≥3 days.
* Asymptomatic biochemical laboratory abnormalities, other than TLS, that resolve in 7 days or less.
For patients with a dose interruption lasting 7 days or less:
For patients with a dose interruption lasting more than 7 days:

a The physician may restart at a lower dose than noted.
b Resume on Day 1 of the individual restart pack. Instruct patients to follow the dosing schedule printed on the blister card starting on Day 1 (1 tablet daily on Days 1 through 3, then 2 tablets daily on Days 4 through 7).
c Resume on Day 4 of the individual restart pack. Instruct patients to remove and dispose of single tablets labeled Days 1 through 3 and restart taking tablets labeled Day 4 (2 tablets daily) of the individual restart pack.

Concomitant strong CYP3A inhibitors are contraindicated at initiation and during ramp-up of BEQALZI. For dose adjustments after ramp-up, see Table 5. Avoid moderate CYP3A inhibitors during initiation and at the 1 mg and 2 mg dose of sonrotoclax.
Table 5. Management of Potential BEQALZI Interactions with CYP3A Inhibitors:
| Concomitant Drug | During Initiation and Ramp-Up Phase | Target Daily Dose (after ramp-up phase) |
| Strong CYP3A inhibitors | Contraindicated | Reduce BEQALZI dose to 20 mg. |
| Moderate CYP3A inhibitorsa | Avoid concomitant use of moderate CYP3A inhibitors at 1 mg and 2 mg dose of sonrotoclax. Reduce all other doses of sonrotoclax by at least 4-fold (see Table 6). | Reduce BEQALZI dose to 80 mg. |
a Consider alternative medicinal products or reduce the sonrotoclax dose as described in Table 6.
Resume the BEQALZI dosage that was used prior to treatment with a strong or moderate CYP3A inhibitor at least 5 days after discontinuation of the inhibitor.

| 5 mg | 1 mg |
| 10 mg | 2 mg |
| 20 mg | 5 mg |
| 40 mg | 10 mg |

Take BEQALZI tablets with a meal once a day at the same approximate time. Swallow tablets whole with a glass of water. Do not break, chew, or crush the tablets.
If a dose of BEQALZI is missed within 8 hours of when it is usually taken, instruct the patient to take the missed dose as soon as possible with a meal and resume the normal daily dosing schedule. If a dose is missed by more than 8 hours, instruct the patient to not take the missed dose, and resume the usual dosing schedule the next day.
If the patient vomits following a dose, instruct the patient to not take an additional dose that day, and resume the usual dosing schedule the next day.
Store at 20°C to 25°C (68°F to 77°F); excursions permitted between 15°C and 30°C (59°F to 86°F) [See USP Controlled Room Temperature].
