DOXIL Dailymed

3 Dosage Forms And Strengths

DOXIL (doxorubicin hydrochloride liposome injection): 20 mg/10 mL (2 mg/mL) and 50 mg/25 mL (2 mg/mL) translucent, red liposomal dispersion in single dose vials.


Doxorubicin hydrochloride liposomal injection: 20 mg/10 mL (2 mg/mL) and 50 mg/25 mL (2 mg/mL) in single dose vials (3)

4 Contraindications

DOXIL liposomal infusion is contraindicated in patients who have a history of severe hypersensitivity reactions, including anaphylaxis, to doxorubicin hydrochloride [see Warnings and Precautions (5.2)].

• •Hypersensitivity reactions to doxorubicin hydrochloride or the components of DOXIL liposomal infusion (4, 5.2)

5 Warnings And Precautions

• •Hand-Foot Syndrome may occur. Dose modification or discontinuation may be required (5.3)
• •Embryo-Fetal Toxicity: Can cause fetal harm. Advise of potential risk to a fetus. Use effective contraception (5.5, 8.1, 8.3)

5.1 Cardiomyopathy

Doxorubicin hydrochloride can cause myocardial damage, including acute left ventricular failure. The risk of cardiomyopathy with doxorubicin hydrochloride is generally proportional to the cumulative exposure. Include prior use of other anthracyclines or anthracenediones in calculations of cumulative dose. The risk of cardiomyopathy may be increased at lower cumulative doses in patients with prior mediastinal irradiation.

In a clinical study in 250 patients with advanced cancer who were treated with DOXIL liposomal infusion, the risk of cardiomyopathy was 11% when the cumulative anthracycline dose was between 450 mg/m² to 550 mg/m². Cardiomyopathy was defined as >20% decrease in resting left ventricular ejection fraction (LVEF) from baseline where LVEF remained in the normal range or a >10% decrease in LVEF from baseline where LVEF was less than the institutional lower limit of normal. Two percent of patients developed signs and symptoms of congestive heart failure without documented evidence of cardiomyopathy.

Assess left ventricular cardiac function (e.g. MUGA or echocardiogram) prior to initiation of DOXIL liposomal infusion, during treatment to detect acute changes, and after treatment to detect delayed cardiomyopathy. Administer DOXIL liposomal infusion to patients with a history of cardiovascular disease only when the potential benefit of treatment outweighs the risk.

5.2 Infusion-Related Reactions

Serious, life-threatening, and fatal infusion-related reactions characterized by one or more of the following symptoms can occur with DOXIL liposomal infusion: flushing, shortness of breath, facial swelling, headache, chills, chest pain, back pain, tightness in the chest and throat, fever, tachycardia, pruritus, rash, cyanosis, syncope, bronchospasm, asthma, apnea, and hypotension. Of 239 patients with ovarian cancer treated with DOXIL liposomal infusion in Trial 4, 7% of patients experienced acute infusion-related reactions resulting in dose interruption. All occurred during cycle 1 and none during subsequent cycles. Across multiple studies of DOXIL liposomal infusion monotherapy including this and other studies enrolling 760 patients with various solid tumors, 11% of patients had infusion-related reactions. The majority of infusion-related events occurred during the first infusion.

Ensure that medications to treat infusion-related reactions and cardiopulmonary resuscitative equipment are available for immediate use prior to initiation of DOXIL liposomal infusion. Initiate DOXIL liposomal infusions at a rate of 1 mg/min and increase rate as tolerated [see Dosage and Administration (2.6)]. Withhold DOXIL liposomal infusion for Grade 1, 2, or 3 infusion-related reactions and resume at a reduced infusion rate. Discontinue DOXIL liposomal infusion for serious or life-threatening infusion-related reactions.

5.3 Hand-Foot Syndrome (HFS)

In Trial 4, the incidence of HFS was 51% of patients in the DOXIL liposomal infusion arm and 0.9% of patients in the topotecan arm, including 24% Grade 3 or 4 cases of HFS in DOXIL liposomal infusion-treated patients and no Grade 3 or 4 cases in topotecan-treated patients. HFS or other skin toxicity required discontinuation of DOXIL liposomal infusion in 4.2% of patients.

HFS was generally observed after 2 or 3 cycles of treatment but may occur earlier. Delay DOXIL liposomal infusion for the first episode of Grade 2 or greater HFS [see Dosage and Administration (2.5)]. Discontinue DOXIL liposomal infusion if HFS is severe and debilitating.

5.4 Secondary Oral Neoplasms

Secondary oral cancers, primarily squamous cell carcinoma, have been reported from post-marketing experience in patients with long-term (more than one year) exposure to DOXIL liposomal infusion. These malignancies were diagnosed both during treatment with DOXIL liposomal infusion and up to 6 years after the last dose. Examine patients at regular intervals for the presence of oral ulceration or with any oral discomfort that may be indicative of secondary oral cancer.

The altered pharmacokinetics and preferential tissue distribution of liposomal doxorubicin that contributes to enhanced skin toxicity and mucositis compared to free doxorubicin may play a role in the development of oral secondary malignancies with long-term use.

5.5 Embryo-Fetal Toxicity

Based on findings in animals and its mechanism of action, DOXIL liposomal infusion can cause fetal harm when administered to a pregnant woman; avoid the use of DOXIL liposomal infusion during the 1^st trimester. Available human data do not establish the presence or absence of major birth defects and miscarriage related to the use of doxorubicin hydrochloride during the 2^nd and 3^rd trimesters. At doses approximately 0.12 times the recommended clinical dose, DOXIL liposomal infusion was embryotoxic and abortifacient in rabbits. Advise pregnant women of the potential risk to a fetus. Advise females and males of reproductive potential to use effective contraception during and for 6 months after treatment with DOXIL liposomal infusion [see Use in Specific Populations (8.1, 8.3)].

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed cannot be directly compared to rates on other clinical trials and may not reflect the rates observed in clinical practice.

The safety data reflect exposure to DOXIL liposomal infusion in 1310 patients including: 239 patients with ovarian cancer, 753 patients with AIDS-related Kaposi’s sarcoma, and 318 patients with multiple myeloma.

The most common adverse reactions (>20%) observed with DOXIL liposomal infusion are asthenia, fatigue, fever, nausea, stomatitis, vomiting, diarrhea, constipation, anorexia, hand-foot syndrome, rash and neutropenia, thrombocytopenia and anemia.

The following tables present adverse reactions from clinical trials of single-agent DOXIL liposomal infusion in ovarian cancer and AIDS-Related Kaposi’s sarcoma.

Patients With Ovarian Cancer

The safety data described below are from Trial 4, which included 239 patients with ovarian cancer treated with DOXIL liposomal infusion 50 mg/m² once every 4 weeks for a minimum of four courses in a randomized, multicenter, open-label study. In this trial, patients received DOXIL liposomal infusion for a median number of 3.2 months (range 1 day to 25.8 months). The median age of the patients is 60 years (range 27 to 87), with 91% Caucasian, 6% Black, and 3% Hispanic or Other.

Patients With AIDS-Related Kaposi’s Sarcoma

The safety data described is based on the experience reported in 753 patients with AIDS-related Kaposi’s sarcoma (KS) enrolled in four open-label, uncontrolled trials of DOXIL liposomal infusion administered at doses ranging from 10 to 40 mg/m² every 2 to 3 weeks. Demographics of the population were: median age 38.7 years (range 24–70); 99% male; 88% Caucasian, 6% Hispanic, 4% Black, and 2% Asian/other/unknown. The majority of patients were treated with 20 mg/m² of DOXIL liposomal infusion every 2 to 3 weeks with a median exposure of 4.2 months (range 1 day to 26.6 months). The median cumulative dose was 120 mg/m² (range 3.3 to 798.6 mg/m²); 3% received cumulative doses of greater than 450 mg/m².

Disease characteristics were: 61% poor risk for KS tumor burden, 91% poor risk for immune system, and 47% poor risk for systemic illness; 36% were poor risk for all three categories; median CD4 count 21 cells/mm³ (51% less than 50 cells/mm³); mean absolute neutrophil count at study entry approximately 3,000 cells/mm³.

Of the 693 patients with concomitant medication information, 59% were on one or more antiretroviral medications [35% zidovudine (AZT), 21% didanosine (ddI), 16% zalcitabine (ddC), and 10% stavudine (D4T)]; 85% received PCP prophylaxis (54% sulfamethoxazole/trimethoprim); 85% received antifungal medications (76% fluconazole); 72% received antivirals (56% acyclovir, 29% ganciclovir, and 16% foscarnet) and 48% patients received colony-stimulating factors (sargramostim/filgrastim) during their course of treatment.

Adverse reactions led to discontinuation of treatment in 5% of patients with AIDS-related Kaposi’s sarcoma and included myelosuppression, cardiac adverse reactions, infusion-related reactions, toxoplasmosis, HFS, pneumonia, cough/dyspnea, fatigue, optic neuritis, progression of a non-KS tumor, allergy to penicillin, and unspecified reasons. Table 5 and Table 6 summarize adverse reactions reported in patients treated with DOXIL liposomal infusion for AIDS-related Kaposi’s sarcoma in a pooled analysis of the four trials.

Patients With Multiple Myeloma

The safety data described are from 318 patients treated with DOXIL liposomal infusion (30 mg/m²) administered on day 4 following bortezomib (1.3 mg/m² i.v. bolus on days 1, 4, 8 and 11) every 3 weeks, in a randomized, open-label, multicenter study (Trial 6). In this trial, patients in the DOXIL liposomal infusion + bortezomib combination group were treated for a median number of 4.5 months (range 21 days to 13.5 months). The population was 28 to 85 years of age (median age 61), 58% male, 90% Caucasian, 6% Black, and 4% Asian and Other. Table 7 uls adverse reactions reported in 10% or more of patients treated with DOXIL liposomal infusion in combination with bortezomib for multiple myeloma.

6.2 Postmarketing Experience

The following additional adverse reactions have been identified during postapproval use of DOXIL liposomal infusion. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Musculoskeletal and Connective Tissue Disorders: muscle spasms

Respiratory, Thoracic and Mediastinal Disorders: pulmonary embolism (in some cases fatal)

Hematologic Disorders: Secondary acute myelogenous leukemia

Skin and Subcutaneous Tissue Disorders: erythema multiforme, Stevens‑Johnson syndrome, toxic epidermal necrolysis, lichenoid keratosis

Secondary Oral Neoplasms: [see Warnings and Precautions (5.4)].

7 Drug Interactions

No formal drug interaction studies have been conducted with DOXIL liposomal infusion.

8 Use In Specific Populations

• •Lactation: Discontinue breastfeeding (8.2).

8.1 Pregnancy

Risk Summary

Based on findings in animals and its mechanism of action, DOXIL liposomal infusion can cause fetal harm when administered to a pregnant woman; avoid the use of DOXIL liposomal infusion during the 1^st trimester. In animal reproduction studies, DOXIL liposomal infusion was embryotoxic in rats and abortifacient in rabbits following intravenous administration during organogenesis at doses approximately 0.12 times the recommended clinical dose (see Data). Available human data do not establish the presence or absence of major birth defects and miscarriage related to the use of doxorubicin hydrochloride during the 2^nd and 3^rd trimesters. Advise pregnant women of the potential risk to a fetus.

The background risk of major birth defects and miscarriage for the indicated populations are unknown. However, the background risk in the U.S. general population of major birth defects is 2–4% and of miscarriage is 15–20% of clinically recognized pregnancies.

Data

Animal Data

DOXIL liposomal infusion was embryotoxic at doses of 1 mg/kg/day in rats and was embryotoxic and abortifacient at 0.5 mg/kg/day in rabbits (both doses are about 0.12 times the recommended dose of 50 mg/m² human dose on a mg/m² basis). Embryotoxicity was characterized by increased embryo-fetal deaths and reduced live litter sizes.

8.2 Lactation

Risk Summary

It is not known whether DOXIL liposomal infusion is present in human milk. Because many drugs, including anthracyclines, are excreted in human milk and because of the potential for serious adverse reactions in breastfed infants from DOXIL liposomal infusion, discontinue breastfeeding during treatment with DOXIL liposomal infusion.

8.3 Females and Males of Reproductive Potential

Pregnancy Testing

Verify the pregnancy status of females of reproductive potential prior to initiating DOXIL liposomal infusion.

Contraception

Females

DOXIL liposomal infusion can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during and for 6 months after treatment with DOXIL liposomal infusion.

Males

DOXIL liposomal infusion may damage spermatozoa and testicular tissue, resulting in possible genetic fetal abnormalities. Males with female sexual partners of reproductive potential should use effective contraception during and for 6 months after treatment with DOXIL liposomal infusion [see Non-clinical Toxicology (13.1)].

Infertility

Females

In females of reproductive potential, DOXIL liposomal infusion may cause infertility and result in amenorrhea. Premature menopause can occur with doxorubicin hydrochloride. Recovery of menses and ovulation is related to age at treatment.

Males

DOXIL liposomal infusion may result in oligospermia, azoospermia, and permanent loss of fertility. Sperm counts have been reported to return to normal levels in some men. This may occur several years after the end of therapy [see Non-clinical Toxicology (13.1)].

8.4 Pediatric Use

The safety and effectiveness of DOXIL liposomal infusion in pediatric patients have not been established.

8.5 Geriatric Use

Clinical studies of DOXIL liposomal infusion conducted in patients with either epithelial ovarian cancer (Trial 4) or with AIDS-related Kaposi’s sarcoma (Trial 5) did not contain sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger subjects.

In Trial 6, of 318 patients treated with DOXIL liposomal infusion in combination with bortezomib for multiple myeloma, 37% were 65 years of age or older and 8% were 75 years of age or older. No overall differences in safety or efficacy were observed between these patients and younger patients.

8.6 Hepatic Impairment

The pharmacokinetics of DOXIL liposomal infusion has not been adequately evaluated in patients with hepatic impairment. Doxorubicin is eliminated in large part by the liver. Reduce DOXIL liposomal infusion for serum bilirubin of 1.2 mg/dL or higher.

10 Overdosage

Acute overdosage with doxorubicin hydrochloride causes increased risk of severe mucositis, leukopenia, and thrombocytopenia.

11 Description

The active ingredient in DOXIL liposomal infusion is doxorubicin hydrochloride, an anthracycline topoisomerase inhibitor, that is encapsulated in STEALTH liposomes for intravenous use.

The chemical name of doxorubicin hydrochloride is (8S,10S)-10-[(3-amino-2,3,6‑trideoxy-α-L-lyxo-hexopyranosyl)oxy]-8-glycolyl-7,8,9,10-tetrahydro-6,8,11‑trihydroxy-1-methoxy-5,12-naphthacenedione hydrochloride. The molecular formula is C27-H29 -NO11•HCl and the molecular weight is 579.99.

The structural formula is:

DOXIL liposomal infusion is a sterile, translucent, red liposomal dispersion. Each single- dose vial contains 20 mg or 50 mg doxorubicin hydrochloride at a concentration of 2 mg/mL (equivalent to 1.87 mg/mL of doxorubicin). The STEALTH liposome carriers are composed of cholesterol, 3.19 mg/mL; fully hydrogenated soy phosphatidylcholine (HSPC), 9.58 mg/mL; and N-(carbonyl-methoxypolyethylene glycol 2000)-1,2-distearoyl-sn-glycero-3-phosphoethanolamine sodium salt (MPEG-DSPE), 3.19 mg/mL. Each mL also contains ammonium sulfate, approximately 0.6 mg; histidine, 1.55 mg as a buffer; hydrochloric acid and/or sodium hydroxide may have been added for pH adjustment (6.0 to 7.0); and sucrose, 94 mg to maintain isotonicity. Greater than 90% of the drug is encapsulated in the STEALTH liposomes.

MPEG-DSPE has the following structural formula:

HSPC has the following structural formula:

12 Clinical Pharmacology

12.1 Mechanism of Action

The active ingredient of DOXIL liposomal infusion is doxorubicin hydrochloride. The mechanism of action of doxorubicin hydrochloride is thought to be related to its ability to bind DNA and inhibit nucleic acid synthesis. Cell structure studies have demonstrated rapid cell penetration and perinuclear chromatin binding, rapid inhibition of mitotic activity and nucleic acid synthesis, and induction of mutagenesis and chromosomal aberrations.

12.3 Pharmacokinetics

The pharmacokinetic parameters for total doxorubicin following a single dose of DOXIL infused over 30 minutes are presented in Table 8.

Table 8: Pharmacokinetic Parameters of Total Doxorubicin from DOXIL Liposomal Infusion in Patients With AIDS-Related Kaposi’s Sarcoma

	Dose
Parameter (units)	10 mg/m2	20 mg/m2
N=23Mean ± Standard Error
Peak Plasma Concentration (µg/mL)	4.12 ± 0.215	8.34 ± 0.49
Plasma Clearance (L/h/m2)	0.056 ± 0.01	0.041 ± 0.004
Steady State Volume of Distribution (L/m2)	2.83 ± 0.145	2.72 ± 0.120
AUC (µg/mL∙h)	277 ± 32.9	590 ± 58.7
First Phase (λ1) Half-Life (h)	4.7 ± 1.1	5.2 ± 1.4
Second Phase (λ1) Half-Life (h)	52.3 ± 5.6	55.0 ± 4.8

DOXIL liposomal infusion displayed linear pharmacokinetics over the range of 10 to 20 mg/m². Relative to DOXIL liposomal infusion doses at or below 20 mg/m², the pharmacokinetics of total doxorubicin following a 50 mg/m² DOXIL liposomal infusion dose are nonlinear. At this dose, the elimination half-life of DOXIL liposomal infusion is longer and the clearance lower compared to a 20 mg/m² dose.

Distribution

Direct measurement of liposomal doxorubicin shows that at least 90% of the drug (the assay used cannot quantify less than 5–10% free doxorubicin) remains liposome-encapsulated during circulation.

In contrast to doxorubicin, which displays a large volume of distribution (range 700 to 1100 L/m²), the small steady state volume of distribution of liposomal doxorubicin suggests that DOXIL liposomal infusion is largely confined to vascular fluid. Doxorubicin becomes available after the liposomes are extravasated. Plasma protein binding of DOXIL liposomal infusion has not been determined; the plasma protein binding of doxorubicin is approximately 70%.

Metabolism

Doxorubicinol, the major metabolite of doxorubicin, was detected at concentrations of 0.8 to 26.2 ng/mL in the plasma of patients who received 10 or 20 mg/m² DOXIL liposomal infusion.

Elimination

The plasma clearance of total doxorubicin from DOXIL liposomal infusion was 0.041 L/h/m² at a dose of 20 mg/m². Following administration of doxorubicin hydrochloride, the plasma clearance of doxorubicin is 24 to 35 L/h/m².

13 Non-clinical Toxicology

13.1 Carcinogenesis, Mutagenesis, and Impairment of Fertility

Mutagenicity or carcinogenicity studies have not been conducted with DOXIL liposomal infusion, however doxorubicin was shown to be mutagenic in the in vitro Ames assay, and clastogenic in multiple in vitro assays (CHO cell, V79 hamster cell, human lymphoblast, and SCE assays) and the in vivo mouse micronucleus assay. The possible adverse effects on fertility in animals have not been adequately evaluated. DOXIL liposomal infusion resulted in mild to moderate ovarian and testicular atrophy in mice after administration of a single dose of 36 mg/kg (about 2 times the 50 mg/m² human dose on a mg/m² basis). Decreased testicular weights and hypospermia were observed in rats after repeat doses ≥ 0.25 mg/kg/day (about 0.03 times the 50 mg/m² human dose on a mg/m² basis), and diffuse degeneration of the seminiferous tubules and a marked decrease in spermatogenesis were observed in dogs after repeat doses of 1 mg/kg/day (about 0.4 times the 50 mg/m² human dose on a mg/m² basis).

14 Clinical Studies

14.1 Ovarian Cancer

DOXIL liposomal infusion was studied in three open-label, single-arm, clinical studies of 176 patients with metastatic ovarian cancer (Trials 1, 2, and 3). One hundred forty-five of these patients were refractory to both paclitaxel- and platinum-based chemotherapy regimens, defined as disease progression while on treatment or relapse within 6 months of completing treatment. Patients received DOXIL liposomal infusion at 50 mg/m² every 3 or 4 weeks for 3–6+ cycles in the absence of dose-limiting toxicity or disease progression.

The median age at diagnosis ranged from 52 to 64 years in the 3 studies, and the range was 22 to 85. Most patients had International Federation of Obstetricians and Gynecologists (FIGO) stage III or IV disease (ranging from 83% to 93%). Approximately one third of the patients had three or more prior lines of therapy (ranging from 22% to 33%).

The primary outcome measure was confirmed response rate based on Southwestern Oncology Group (SWOG) criteria for patients refractory to both paclitaxel- and a platinum-containing regimen. Secondary efficacy parameters were time to response, duration of response, and time to progression.

The response rates for the individual single arm trials are given in Table 9 below.

Table 9: Response Rates in Patients With Refractory Ovarian Cancer From Single Arm Ovarian Cancer Trials

	Trial 1 (U.S.) N=27	Trial 2 (U.S.) N=82	Trial 3 (non-U.S.) N=36
Response Rate	22.2%	17.1%	0%
95% Confidence Interval	8.6% – 42.3%	9.7% – 27.0%	0.0% – 9.7%

In a pooled analysis of Trials 1–3, the response rate for all patients refractory to paclitaxel and platinum agents was 13.8% (95% CI 8.1% to 19.3%). The median time to progression was 15.9 weeks, the median time to response was 17.6 weeks, and the duration of response was 39.4 weeks.

In Trial 4, a randomized, multicenter, open-label, trial in 474 patients with epithelial ovarian cancer after platinum-based chemotherapy, patients were randomized to receive either DOXIL liposomal infusion 50 mg/m² every 4 weeks (n=239) or topotecan 1.5 mg/m² daily for 5 consecutive days every 3 weeks (n=235). Patients were stratified according to platinum sensitivity (response to initial platinum-based therapy and a progression-free interval of greater than 6 months off treatment) and the presence of bulky disease (tumor mass greater than 5 cm in size). The primary outcome measure was time to progression (TTP). Other endpoints included overall survival and objective response rate.

Of the 474 patients, the median age at diagnosis was 60 years (range 25 to 87), 90% were FIGO stage III and IV; 46% were platinum sensitive; and 45% had bulky disease.

There was no statistically significant difference in TTP between the two arms. Results are provided in Table 10.

14.2 AIDS-Related Kaposis Sarcoma

DOXIL liposomal infusion was studied in an open-label, single-arm, multicenter study at a dose of 20 mg/m² every 3 weeks, until disease progression or unacceptable toxicity (Trial 5).

Data is described for a cohort of 77 patients retrospectively identified as having disease progression on prior systemic combination chemotherapy (at least two cycles of a regimen containing at least two of three treatments: bleomycin, vincristine or vinblastine, or doxorubicin) or as being intolerant to such therapy. Forty-nine of the 77 (64%) patients had received prior doxorubicin hydrochloride.

The median time on study was 5.1 months (range 1 day to 15 months). The median cumulative dose of DOXIL liposomal infusion was 154 mg/m² (range 20 to 620 mg/m²). Among the 77 patients, mean age was 38 years (range 24 to 54); 87% were Caucasian, 5% Hispanic, 4% Black, and 4% Asian/Other/Unknown; median CD4 count was 10 cells/mm³; ACTG staging criteria were 78% poor risk for tumor burden, 96% poor risk for immune system, and 58% poor risk for systemic illness at baseline; and mean Karnofsky status score was 74%. All patients had cutaneous or subcutaneous lesions, 40% also had oral lesions, 26% pulmonary lesions, and 14% had lesions of the stomach/intestine.

Two analyses of tumor response were used: one based on investigator assessment of changes in lesions based on modified ACTG criteria (partial response defined as no new lesions, sites of disease, or worsening edema; flattening of ≥50% of previously raised lesions or area of indicator lesions decreasing by ≥50%; and response lasting at least 21 days with no prior progression), and one based on changes in up to five prospectively indentified representative indicator lesions (partial response defined as flattening of ≥50% of previously raised indicator lesions, or >50% decrease in the area of indicator lesions and lasting at least 21 days with no prior progression).

Of the 77 patients, 34 were evaluable for investigator assessment and 42 were evaluable for indicator lesion assessment; analyses of tumor responses are shown in Table 11.

Retrospective efficacy analyses were performed in two trials that had subsets of patients who received single-agent DOXIL liposomal infusion and who were on stable antiretroviral therapy for at least 60 days prior to enrollment and until a response was demonstrated. In one trial, 7 of 17 (40%) patients had a durable response (median duration not reached but was longer than 11.6 months). In the second trial, 4 of 11 patients (40%) on a stable antiretroviral therapy demonstrated durable responses.

14.3 Multiple Myeloma

The efficacy of DOXIL liposomal infusion in combination with bortezomib was evaluated in Trial 6, a randomized, open-label, international, multicenter study in 646 patients who had not previously received bortezomib and whose disease progressed during or after at least one prior therapy. Patients were randomized (1:1) to receive either DOXIL liposomal infusion (30 mg/m²) administered IV on day 4 following bortezomib (1.3 mg/m² IV on days 1, 4, 8 and 11) or bortezomib alone every 3 weeks for up to 8 cycles or until disease progression or unacceptable toxicity. Patients who maintained a response were allowed to receive further treatment. The median number of cycles in each treatment arm was 5 (range 1–18).

The baseline demographics and clinical characteristics of the patients with multiple myeloma were similar between treatment arms (Table 12).

The primary outcome measure was time to progression (TTP). TTP was defined as the time from randomization to the first occurrence of progressive disease or death due to progressive disease. The combination arm demonstrated significant improvement in TTP. As the prespecified primary objective was achieved at the interim analysis, patients in the bortezomib monotherapy group were then allowed to receive the DOXIL liposomal infusion + bortezomib combination. Efficacy results are as shown in Table 13 and Figure 1 .

Figure 1- Time to Progression Kaplan-Meier Curve

At the final analysis of survival, 78% of subjects in the DOXIL liposomal infusion and bortezomib combination therapy group and 80% of subjects in the bortezomib monotherapy group had died after a median follow up of 8.6 years. The median survival was 33 months in the DOXIL liposomal infusion and bortezomib combination therapy group and 31 months in the bortezomib monotherapy group. There was no difference observed in overall survival at the final analysis [HR for DOXIL liposomal infusion + bortezomib vs. bortezomib = 0.96 (95% CI 0.80, 1.14)].

Seventy-eight percent of subjects in the DOXIL liposomal infusion and bortezomib combination therapy group and 80% of subjects in the bortezomib monotherapy group had received subsequent therapy.
